                Covered Asset Acquisitions
                AGENCY: Internal Revenue Service (IRS), Treasury.
                ACTION: Final regulations and removal of temporary regulations.
                -----------------------------------------------------------------------
                SUMMARY: This document contains final Income Tax Regulations under
                section 901(m) of the Internal Revenue Code (Code) with respect to
                transactions that generally are treated as asset acquisitions for U.S.
                income tax purposes and either are treated as stock acquisitions or are
                disregarded for foreign income tax purposes. These regulations are
                necessary to provide guidance on applying section 901(m). These
                regulations affect taxpayers claiming foreign tax credits.
                DATES:
                 Effective date: These regulations are effective on March 23, 2020.
                 Applicability dates: For dates of applicability, see Sec. Sec.

                SUPPLEMENTARY INFORMATION:
                Background
                 On December 7, 2016, both a notice of proposed rulemaking by cross-
                reference in part to temporary regulations (REG-129128-14) (2016
                proposed regulations) under sections 901(m) and 704 of the Code and
                temporary regulations (TD 9800) under section 901(m) were published in
                the Federal Register at 81 FR 88562 and 81 FR 88103. The temporary and
                proposed regulations include the rules described in Notice 2014-44
                (2014-32 I.R.B. 270 (August 4, 2014)) and Notice 2014-45 (2014-34
                I.R.B. 388 (August 18, 2014).
                 A public hearing was not requested, and none was held. However, the
                Department of the Treasury (Treasury Department) and the IRS received
                written comments in response to the notice of proposed rulemaking.
                After consideration of all the comments, the 2016 proposed regulations
                under section 901(m) are adopted as revised by this Treasury decision.
                The revisions are discussed in this preamble. This Treasury decision
                also adopts the 2016 proposed regulations under section 704 without
                revision. The regulations adopted by this Treasury decision are
                referred to herein as the ``final regulations.'' Defined terms used in
                this preamble but not defined herein have the meaning provided in the
                final regulations.
                Summary of Comments and Explanation of Revisions
                1. Scope of Covered Asset Acquisitions (CAAs)
                 Proposed Sec. 1.901(m)-2(b) identifies six categories of
                transactions that constitute CAAs, three of which are specified in the
                statute and three of which are additional categories of transactions
                that are identified as CAAs pursuant to the authority granted under
                section 901(m)(2)(D).
                 One comment requested that an exemption to section 901(m) be
                provided for CAAs in which all or substantially all of the gains and
                losses with respect to the relevant foreign assets (RFAs) are
                recognized by members of the U.S.-parented group that includes the
                section 901(m) payor. The comment suggested that the policies of
                section 901(m) are not implicated in such a situation because if the
                same group takes into account the gains on the RFAs up front and then,
                in the future recognizes offsetting cost recovery items on those
                assets, over time, the U.S. income tax base is unchanged.
                 The Treasury Department and IRS agree that an exemption would be
                appropriate in certain cases, but have determined that the comment's
                suggestion is overbroad. As proposed by the comment, the exemption
                would apply to U.S. members of an affiliated group that do not file a
                consolidated return and to related controlled foreign corporations.
                This leaves open the possibility of manipulation of foreign tax
                credits. For example, in the case of affiliated but non-consolidated
                U.S. entities, the entity recognizing the U.S. gain on the assets up
                front may be an entity that is exempt from tax under section 501 while
                the entity recognizing the offsetting cost recovery items may be in a
                position to take advantage of the excess foreign taxes related to the
                basis difference.
                 The Treasury Department and IRS have determined that the exemption
                should apply only if a domestic section 901(m) payor or a member of its
                consolidated group recognized the gains or losses or took into account
                a distributive share of the gains or losses recognized by a partnership
                for U.S. tax purposes as part of the original CAA. Accordingly, the
                definition of aggregate basis difference is modified to take into
                account allocated basis difference adjustments determined based on gain
                or loss recognized with respect to an RFA as a result of a CAA. See
                Sec. 1.901(m)-1(a)(1), (6), (48), and (49). For example, if one
                domestic corporation, USS1, sold a foreign disregarded entity (FDE)
                that held an asset to another member of its consolidated group, USS2,
                the transaction is a CAA, because it is an asset sale for U.S. income
                tax purposes and an acquisition of stock of the FDE for foreign tax
                purposes. As a result, the asset is an RFA owned by USS2 subject to
                section 901(m). However, any aggregate basis difference USS2 determines
                with respect to the RFA will be adjusted to take into account the gain
                recognized for U.S. income tax purposes by USS1 on the original sale,
                provided USS1 and USS2 are still members of the same consolidated group
                in the year the allocated basis difference is determined.
                 Another comment suggested that the final category of transactions,
                which includes any asset acquisition for U.S. and foreign income tax
                purposes that results in an increase in the U.S. basis
                [[Page 16246]]
                without a corresponding increase in the foreign basis, be replaced with
                one or more specifically defined transactions. The comment recommended
                that new CAAs be limited to specific transactions that are likely to
                achieve the same hyping of foreign tax credits as the three categories
                of CAAs specified in the statute and that typically involve intensive
                U.S. tax planning. The comment also suggested that if the Treasury
                Department and IRS found a list of specific transactions to be too
                limited, they could add an anti-abuse rule that would treat any
                transaction as a CAA if it was structured with a principal purpose of
                avoiding the specific categories of transactions set forth in the
                revised list of transactions.
                 The Treasury Department and IRS do not agree that the final
                category of transactions is overbroad. Section 901(m) is designed to
                address transactions that result in a basis difference for U.S. and
                foreign income tax purposes. There is no intent test. Proposed Sec.
                1.901(m)-7 provides a de minimis exception that relieves the burden of
                applying section 901(m) to ordinary course transactions below the
                threshold provided in that rule. The Treasury Department and IRS have
                determined there is no policy justification for exempting transactions
                to which this exception does not apply on the grounds that the
                transaction lacked an intent to hype foreign taxes, and replacing this
                category of transactions with an anti-abuse rule would inappropriately
                introduce an intent component that is not required by the statute.
                Accordingly, the comment is not adopted.
                2. Aggregate Basis Difference Carryover
                 Proposed Sec. 1.901(m)-3(c) provides rules for determining the
                amount of aggregate basis difference carryover for a given U.S. taxable
                year of a section 901(m) payor that will be included in the section
                901(m) payor's aggregate basis difference for the next U.S. taxable
                year. The carryover reflects the extent to which the aggregate basis
                difference for a U.S. taxable year has not yet given rise to a
                disqualified tax amount.
                 A comment requested that the aggregate basis difference carryover
                rule be eliminated due to the increased compliance costs resulting from
                the added complexity of tracking the carryover amounts. The comment
                argued that these compliance costs are unjustified, given that Congress
                enacted an administrable approach in the statute and did not express
                any intent that carryover rules could apply.
                 The Treasury Department and IRS have determined that the aggregate
                basis difference carryover rule is necessary to prevent the avoidance
                of the purpose of section 901(m), particularly in the case of timing
                differences. For example, assume a section 901(m) payor that is also a
                foreign payor has a foreign taxable year ending on March 31 and a U.S.
                taxable year ending on December 31. Assume further that the section
                901(m) payor recognizes foreign gain on the disposition of an RFA on
                November 30, in U.S. tax year 1. For U.S. income tax purposes, because
                the disposition occurs in U.S. tax year 1, the section 901(m) payor
                will have allocated basis difference in U.S. tax year 1, requiring a
                calculation of a disqualified tax amount. For foreign income tax
                purposes, the foreign tax on the gain is not imposed until the end of
                the foreign taxable year, which is March 31, in U.S. tax year 2.
                Assuming the section 901(m) payor does not pay any other foreign taxes,
                the disqualified tax amount for U.S. tax year 1 will be zero, because
                the foreign taxes are not taken into account by the section 901(m)
                payor for U.S. income tax purposes until U.S. tax year 2. Because the
                allocated basis difference in U.S. tax year 1 does not give rise to a
                disqualified tax amount, the aggregate basis difference carryover rule
                requires that the allocated basis difference be carried into U.S. tax
                year 2 and be used to calculate a disqualified tax amount with respect
                to the foreign taxes taken into account in U.S. tax year 2. Without the
                aggregate basis difference carryover rule, there would be no
                disqualified tax amount in U.S. tax year 1, because there are not
                foreign taxes taken into account in that year, and no disqualified tax
                amount in U.S. tax year 2, because there is no allocated basis
                difference in that year. This would allow avoidance of the application
                of section 901(m) to a fact pattern that is clearly meant to be covered
                by the statute. The aggregate basis difference carryover rule also
                prevents taxpayers from avoiding the application of section 901(m) by
                timing dispositions of RFAs to coincide with offsetting unrelated
                foreign losses. For these reasons, the comment is not adopted.
                3. Foreign Basis Election
                 Basis difference with respect to an RFA is generally equal to the
                U.S. basis in the RFA immediately after a CAA less the U.S. basis in
                the RFA immediately before the CAA. Proposed Sec. 1.901(m)-4(c)
                provides that a taxpayer may instead elect to determine basis
                difference as the U.S. basis in the RFA immediately after the CAA less
                the foreign basis in the RFA immediately after the CAA. This is
                referred to as the foreign basis election. Paragraphs (c) and (g)(3) of
                proposed Sec. 1.901(m)-4 provide that taxpayers may apply the foreign
                basis election retroactively to CAAs that have occurred on or after
                January 1, 2011, provided that the taxpayer applies all of the rest of
                the rules in the 2016 proposed regulations retroactively, with a few
                limited exceptions.
                 One comment suggested that though this consistency requirement is
                appropriate for tax years that remain open, the requirement is unfair
                if some tax years of the taxpayer or its affiliates are already closed.
                The comment recommended the consistency requirement be modified to
                permit taxpayers to apply the foreign basis election as long as they
                apply the rules in the 2016 proposed regulations consistently to all
                relevant tax years that remain open.
                 The Treasury Department and IRS agree that taxpayers should not be
                denied the choice to retroactively apply the foreign basis election
                because a closed tax year is preventing them from satisfying the
                consistency requirement. However, because the statute of limitations
                for refunds attributable to foreign tax credits is ten years while the
                statute of limitations for assessment is generally only three years,
                the only relevant tax years of the taxpayer or its affiliates that
                would be closed are the tax years in which a consistent application of
                the regulations would result in an assessment. The Treasury Department
                and IRS do not believe taxpayers should be able to obtain the benefits
                of retroactive application of the regulations while avoiding the
                negative consequences. Accordingly, while the consistency requirement
                has been modified to apply only for tax years that remain open, an
                additional requirement is added that any deficiencies be taken into
                account that would have resulted from the consistent application of the
                final regulations for a tax year that is closed. See Sec. 1.901(m)-
                4(g)(3). For example, assume a taxpayer chooses to make a retroactive
                foreign basis election that would give rise to a $6 million refund in a
                prior year that is open under the statute of limitations for refunds
                but that a consistent retroactive application of another provision of
                the final regulations would give rise to a $1 million deficiency in
                another prior year that is closed under the statute of limitations for
                assessment. In this case, in order to meet the consistency requirement,
                the taxpayer would need to reduce its refund claim in the open year
                from $6 million to $5 million to take into account the $1 million
                deficiency that would have resulted in the closed tax year.
                [[Page 16247]]
                4. Successor Rules
                 The successor rules in proposed Sec. 1.901(m)-6(b) provide that
                section 901(m) continues to apply to any unallocated basis difference
                with respect to an RFA after there is a transfer of the RFA for U.S.
                income tax purposes, regardless of whether the transfer is a
                disposition, a CAA, or a non-taxable transaction. For example, if a
                section 901(m) payor contributes an RFA with respect to a prior CAA to
                a partnership, any unallocated basis difference in the RFA remains
                subject to the section 901(m) in the hands of the partnership. One
                comment suggested that the Treasury Department and IRS consider whether
                it would be appropriate to apply principles similar to those of section
                704(c) to treat the section 901(m) ``taint'' in the RFA as a built-in
                item that is allocated back to the contributing partner.
                 The Treasury Department and IRS have considered this comment and
                determined that the provisions in proposed Sec. 1.901(m)-5 for
                allocating basis difference to partners in a partnership that owns RFAs
                reflect the most appropriate approach, whether the RFAs are contributed
                to the partnership in a successor transaction or the partnership
                acquires them directly in a CAA. These allocation rules are based on
                the principle that the partner that takes into account the basis
                difference is the one that should be subject to section 901(m). For
                example, if there is a cost recovery amount of 20x due to increased
                depreciation deductions related to a U.S. basis step-up in a CAA,
                section 901(m) basically operates to disallow a credit for foreign
                taxes on that 20x differential created between income for U.S. and
                foreign tax purposes. The 2016 proposed regulations take the approach
                that the partner to whom the 20x of increased depreciation is allocated
                is the one that benefits from the income differential and is therefore
                the one to whom the section 901(m) disallowance should apply. If some
                other partner contributed the RFA to the partnership but does not get
                an allocation of the increased depreciation deductions, the Treasury
                Department and IRS see no policy reason to nevertheless subject the
                contributing partner to the section 901(m) disallowance.
                5. De Miminis Threshold
                 Proposed Sec. 1.901(m)-7 describes de minimis rules under which
                certain basis differences are not taken into account for purposes of
                section 901(m). In general, under the 2016 proposed regulations, a
                basis difference with respect to an RFA is not taken into account for
                purposes of section 901(m) if either (i) the sum of the basis
                differences for all RFAs with respect to the CAA is less than the
                greater of $10 million or 10 percent of the total U.S. basis of all
                RFAs immediately after the CAA; or (ii) the RFA is part of a class of
                RFAs for which the sum of the basis differences of all RFAs in the
                class is less than the greater of $2 million or 10 percent of the total
                U.S. basis of all RFAs in the class immediately after the CAA. The
                threshold dollar amounts and percentages to meet the de minimis
                exemptions for related-party CAAs are lower than those for unrelated
                party CAAs, replacing the terms ``$10 million,'' ``10 percent,'' and
                ``$2 million'' with the terms ``$5 million,'' ``5 percent,'' and ``$1
                million,'' respectively.
                 One comment expressed the view that the threshold amounts for the
                de minimis rules were too low, noting that the potential basis
                differential with respect to transactions of those magnitudes would not
                generate a sufficient foreign tax credit benefit to justify intensive
                tax planning. The comment suggested raising the $10 million threshold
                to $15 million. The comment also recommended eliminating the reduced de
                minimis thresholds in the context of related-party transactions. The
                comment argued that the test should be different for related parties
                only if the fact that the parties are related somehow makes the rules
                less burdensome than they are for unrelated parties or makes the
                likelihood of tax arbitrage higher. The comment suggested that this was
                unlikely to be the case in the context of section 901(m).
                 Although the Treasury Department and the IRS do not believe that
                the comment made a compelling argument for increasing the threshold for
                the cumulative basis difference exemption, the Treasury Department and
                IRS agree that it is appropriate to extend the scope of the de minimis
                rules in order to further reduce the burden of compliance with the
                rules. However, rather than increasing the threshold amount, the
                Treasury Department and IRS have decided to add an additional
                exclusion, such that a basis difference with respect to an individual
                RFA is not taken into account for purposes of section 901(m) if the
                basis difference is less than $20,000. See Sec. 1.901(m)-7(b)(4). Like
                the de minimis exceptions contained in the 2016 proposed regulations,
                this de minimis exception applies independently of the other de minimis
                exceptions. Moreover, the reduced thresholds for related-party
                transactions are eliminated, as suggested by the comment. See Sec.
                1.901(m)-7(c).
                6. Interaction With Section 909
                 One comment requested adding a priority rule to the regulations to
                address transactions to which both section 901(m) and section 909
                apply, such as, for example, the acquisition of a reverse hybrid with
                respect to which a section 338 election is made. The acquisition is a
                CAA under section 901(m), and the reverse hybrid structure is a
                specified foreign tax credit splitting event under the section 909
                regulations. The comment recommended that, given the complexity of the
                calculation of disqualified tax amounts under section 901(m), those
                calculations should be made first and section 909 should then be
                applied to determine whether any of the remaining foreign taxes are
                suspended.
                 The Treasury Department and IRS agree with the comment that if
                section 901(m) and section 909 apply to the same transaction, the
                section 901(m) calculations should be undertaken before applying
                section 909. However, the comment's recommendation implied that only
                the portion of the foreign taxes that are not disqualified under
                section 901(m) are subject to potential suspension under section 909.
                The Treasury Department and IRS disagree with this implication. Section
                909 defers taking into account foreign taxes for purposes of claiming a
                foreign tax credit or claiming a deduction. Foreign taxes that are
                disqualified for foreign tax credit purposes under section 901(m) but
                remain eligible to be deducted may be subject to deferral under section
                909 as well. The comment's suggestion is adopted with these
                clarifications. See Sec. 1.901(m)-8(d).
                7. Changes Related to the Tax Cuts and Jobs Act (TCJA)
                 The final regulations reflect modifications to the rules contained
                in the 2016 proposed regulations necessary to reflect statutory changes
                by the TCJA, Public Law 115-97 (2017). References to section 902
                corporations are replaced with references to applicable foreign
                corporations, which consist of section 902 corporations before the
                applicability of the TCJA modifications to the foreign tax credit rules
                and controlled foreign corporations thereafter. See Sec. 1.901(m)-
                1(a)(7). In addition, a definition of separate category is added and
                utilized to address the income groupings required under section 960
                following TCJA. See Sec. 1.901(m)-1(a)(42).

                8. Applicability Dates
                 The 2016 proposed regulations were generally proposed to apply to
                CAAs occurring on or after the date of publication of the final
                regulations. However, the 2016 proposed regulations also provided that
                taxpayers could rely on the rules therein before they would otherwise
                be applicable, provided that taxpayers consistently applied proposed
                Sec. 1.901(m)-2 (excluding Sec. 1.901(m)-2(d)) to all CAAs occurring
                on or after December 7, 2016, and consistently applied Sec. 1.704-
                1(b)(4)(viii)(c)(4)(v) through (vii), Sec. 1.901(m)-1, and Sec. Sec.
                1.901(m)-3 through 1.901(m)-8 (excluding Sec. 1.901(m)-4(e)) to all
                CAAs occurring on or after January 1, 2011. For this purpose, persons
                that are related (within the meaning of section 267(b) or 707(b)) were
                treated as a single taxpayer.
                 In order to be consistent with the revised applicability of the
                foreign basis election, as discussed in Part 3 of this Summary of
                Comments and Explanation of Revisions section, and allow the rules in
                the final regulations to be applied retroactively, the final
                regulations provide that taxpayers may choose to apply the rules before
                they would otherwise be applicable, provided that the consistency
                requirements described in the preceding paragraph are met, on any
                original or amended tax return for each taxable year for which the
                application of the provisions affects the tax liability and for which
                the statute of limitations does not preclude assessment or the filing
                of a claim for refund, as applicable. The relevant tax returns for
                taxable years ending before March 23, 2020, must be filed no later than
                March 23, 2021. In the case of taxable years that are not open for
                assessment, appropriate adjustments must be made to take into account
                deficiencies that would have resulted from the consistent application
                of the applicable provisions.
                Special Analyses
                 These final regulations are not subject to review under section
                6(b) of Executive Order 12866 pursuant to the Memorandum of Agreement
                (April 11, 2018) between the Department of the Treasury and the Office
                of Management and Budget regarding review of tax regulations.
                 Pursuant to the Regulatory Flexibility Act (5 U.S.C. chapter 6), it
                is hereby certified that this regulation will not have a significant
                economic impact on a substantial number of small entities. In general,
                foreign corporations are not considered small entities. Nor are U.S.
                taxpayers considered small entities to the extent the taxpayers are
                natural persons or entities other than small entities. Small entities
                are significantly less likely to engage in the types of transactions
                addressed by the regulations than U.S. multinational corporations.
                Moreover, the de minimis rules discussed in Part 5 of the Summary of
                Comments and Explanation of Revisions section further limit the number
                of small entities likely to be subject to the regulations.
                 Pursuant to section 7805(f), the notice of proposed rulemaking
                preceding this regulation was submitted to the Chief Counsel for
                Advocacy of the Small Business Administration for comment on its impact
                on small business. No comments were received.
                Drafting Information
                 The principal author of these regulations is Jeffrey L. Parry of
                the Office of Associate Chief Counsel (International). However, other
                personnel from the Treasury Department and the IRS participated in
                their development.

                occurring on or after March 23, 2020. Taxpayers may, however, choose to
                apply paragraphs (b)(4)(viii)(c)(4)(v) through (vii) of this section
                before the date paragraphs (b)(4)(viii)(c)(4)(v) through (vii) of this

                occurring on or after January 1, 2011, and consistently apply Sec.
                1.901(m)-2 (excluding Sec. 1.901(m)-2(d)) to all CAAs occurring on or
                after December 7, 2016, on any original or amended tax return for each
                taxable year for which the application of the provisions listed in this
                paragraph (b)(1)(ii)(b)(4)(i) affects the tax liability and for which
                the statute of limitations does not preclude assessment or the filing
                of a claim for refund, as applicable;
                 (ii) File all tax returns described in paragraph
                (b)(1)(ii)(b)(4)(i) of this section for any taxable year ending on or
                before March 23, 2020, no later than March 23, 2021; and
                 (iii) Make appropriate adjustments to take into account
                deficiencies that would have resulted from the consistent application
                under paragraph (b)(1)(ii)(b)(4)(i) of this section for taxable years
                that are not open for assessment.

                 (v) Adjustments related to section 901(m). If one or more assets
                owned by a partnership are relevant foreign assets (or RFAs) with
                respect to a foreign income tax, then, solely for purposes of applying
                the safe harbor provisions of paragraph (b)(4)(viii)(a)(1) of this
                section to allocations of CFTEs with respect to that foreign income
                tax, the net income in a CFTE category that includes partnership items
                of income, deduction, gain, or loss attributable to the RFA shall be
                increased by the amount described in paragraph (b)(4)(viii)(c)(4)(vi)
                of this section and reduced by the amount described in paragraph
                (b)(4)(viii)(c)(4)(vii) of this section. Similarly, a partner's CFTE
                category share of income shall be increased by the portion of the
                amount described in paragraph (b)(4)(viii)(c)(4)(vi) of this section
                that is allocated to the partner under Sec. 1.901(m)-5(d) and reduced
                by the
                [[Page 16249]]
                portion of the amount described in paragraph (b)(4)(viii)(c)(4)(vii) of
                this section that is allocated to the partner under Sec. 1.901(m)-
                5(d). The principles of this paragraph (b)(4)(viii)(c)(4)(v) apply
                similarly when a partnership owns an RFA indirectly through one or more
                other partnerships. For purposes of this paragraph
                (b)(4)(viii)(c)(4)(v) and paragraphs (b)(4)(viii)(c)(4)(vi) and
                (b)(4)(viii)(c)(4)(vii) of this section, basis difference is defined in
                Sec. 1.901(m)-4, cost recovery amount is defined in Sec. 1.901(m)-
                5(b)(2), disposition amount is defined in Sec. 1.901(m)-5(c)(2),
                foreign income tax is defined in Sec. 1.901(m)-1(a)(26), RFA is
                defined in Sec. 1.901(m)-2(c), U.S. disposition gain is defined in
                Sec. 1.901(m)-1(a)(52), and U.S. disposition loss is defined in Sec.
                1.901(m)-1(a)(53).
                 (vi) Adjustment amounts for RFAs with a positive basis difference.
                With respect to RFAs with a positive basis difference, the amount
                referenced in paragraph (b)(4)(viii)(c)(4)(v) of this section is the
                sum of any cost recovery amounts and disposition amounts attributable
                to U.S. disposition loss that correspond to partnership items that are
                included in the net income in the CFTE category and that are taken into
                account for the U.S. taxable year of the partnership under Sec.
                1.901(m)-5(d).
                 (vii) Adjustment amounts for RFAs with a negative basis difference.
                With respect to RFAs with a negative basis difference, the amount
                referenced in paragraph (b)(4)(viii)(c)(4)(v) of this section is the
                sum of any cost recovery amounts and disposition amounts attributable
                to U.S. disposition gain that correspond to partnership items that are
                included in the net income in the CFTE category and that are taken into
                account for the U.S. taxable year of the partnership under Sec.
                1.901(m)-5(d).

                Par. 3. Section 1.901(m)-1 is added to read as follows:
                Sec. 1.901(m)-1 Definitions.
                 (a) Definitions. For purposes of section 901(m), this section, and
                Sec. Sec. 1.901(m)-2 through 1.901(m)-8, the following definitions
                apply:
                 (1) The term aggregate basis difference means, with respect to a
                foreign income tax and a foreign payor, the sum of the allocated basis
                differences and the allocated basis difference adjustments for a U.S.
                taxable year of a section 901(m) payor, plus any aggregate basis
                difference carryover from the immediately preceding U.S. taxable year
                of the section 901(m) payor with respect to the foreign income tax and
                foreign payor, as adjusted under Sec. 1.901(m)-6(c). For purposes of
                this definition, if foreign law imposes tax on the combined income
                (within the meaning of Sec. 1.901-2(f)(3)(ii)) of two or more foreign
                payors, all foreign payors whose items of income, deduction, gain, or
                loss are included in the U.S. taxable income or earnings and profits of
                the section 901(m) payor are treated as a single foreign payor.
                Aggregate basis difference is determined with respect to each separate

                combined taxable income (or loss) of such foreign payors, regardless of
                whether such income (or loss) is reflected on a single foreign tax

                adjusted). If foreign law imposes tax on the combined income (within
                the meaning of Sec. 1.901-2(f)(3)(ii)) of two or more foreign payors,
                however, a foreign income tax amount means the amount of tax imposed on
                the combined income, regardless of whether the tax is reflected on a
                single foreign tax return.

                to change its entity classification, or a transaction in which a
                foreign payor that is a partnership terminates under section 708(b)(1),
                provided in each case that the foreign payor's foreign taxable year
                does not close as a result of the transaction, and, if the foreign
                payor is a corporation or a partnership, the foreign payor's U.S.

                 (ii) File all tax returns described in paragraph (b)(3)(i) of this
                section for any taxable year ending on or before March 23, 2020, no
                later than March 23, 2021; and
                 (iii) Make appropriate adjustments to take into account
                deficiencies that would have resulted from the consistent application
                under paragraph (b)(3)(i) of this section for taxable years that are
                not open for assessment.

                0
                Par. 4. Section 1.901(m)-1T is removed.
                0
                Par. 5. Section 1.901(m)-2 is added to read as follows:
                Sec. 1.901(m)-2 Covered asset acquisitions and relevant foreign
                assets.
                 (a) In general. Paragraph (b) of this section sets forth the
                transactions that are covered asset acquisitions (or CAAs). Paragraph
                (c) of this section provides rules for identifying assets that are
                relevant foreign assets (or RFAs) with respect to a CAA. Paragraph (d)
                of this section provides special rules for identifying CAAs and RFAs
                with respect to transactions to which paragraphs (b) and (c) of this
                section do not apply. Paragraph (e) of this section provides examples
                illustrating the rules of this section, and paragraph (f) of this
                section provides applicability dates.
                 (b) Covered asset acquisitions. Except as provided in paragraph (d)
                of this section, the transactions set forth in this paragraph (b) are
                CAAs.
                 (1) A qualified stock purchase (as defined in section 338(d)(3)) to
                which section 338(a) applies (section 338 CAA);
                 (2) Any transaction that is treated as an acquisition of assets for
                U.S. income tax purposes and treated as an acquisition of stock of a
                corporation (or disregarded) for foreign income tax purposes;
                 (3) Any acquisition of an interest in a partnership that has an
                election in effect under section 754 (section 743(b) CAA);
                 (4) Any transaction (or series of transactions occurring pursuant
                to a plan) to the extent it is treated as an acquisition of assets for
                purposes of U.S. income tax and as the acquisition of an interest in a
                fiscally transparent entity for purposes of a foreign income tax;
                 (5) Any transaction (or series of transactions occurring pursuant
                to a plan) to the extent it is treated as a partnership distribution of
                one or more assets the U.S. basis of which is determined by section
                732(b) or 732(d) or to the extent it causes the U.S. basis of the
                partnership's remaining assets to be adjusted under section 734(b),
                provided the transaction results in an increase in the U.S. basis of
                one or more of the assets distributed by the partnership or retained by
                the partnership without a corresponding increase in the foreign basis
                of such assets; and
                 (6) Any transaction (or series of transactions occurring pursuant
                to a plan) to the extent it is treated as an acquisition of assets for
                purposes of both U.S. income tax and a foreign income tax, provided the
                transaction results in an increase in the U.S. basis without a
                corresponding increase in the foreign basis of one or more assets.
                 (c) Relevant foreign asset--(1) In general. Except as provided in
                paragraph (d) of this section, an RFA means, with respect to a foreign
                income tax and a CAA, any asset (including goodwill, going concern
                value, or other intangible) subject to the CAA that is relevant in
                determining foreign income for purposes of the foreign income tax.
                 (2) RFA status with respect to a foreign income tax. An asset is
                relevant in determining foreign income if income, deduction, gain, or
                loss attributable to the asset is taken into account in determining
                foreign income immediately after the CAA, or would be taken into
                account in determining foreign income immediately after the CAA if the
                asset were to give rise to income, deduction, gain, or loss at such
                time.
                 (3) Subsequent RFA status with respect to another foreign income
                tax. After a CAA, an asset will become an RFA with respect to another
                foreign income tax if, pursuant to a plan or series of related
                transactions that have a principal purpose of avoiding the application
                of section 901(m), an asset that was not relevant in determining
                foreign income for purposes of that foreign income tax immediately
                after the CAA becomes relevant in determining such foreign income. A
                principal purpose of avoiding section 901(m) will be deemed to exist if
                income, deduction, gain, or loss attributable to the asset is taken
                into account in determining such foreign income within the one-year
                period following the CAA, or would be taken into account in determining
                such foreign income during such time if the asset were to give rise to
                income, deduction, gain, or loss within the one-year period.
                 (d) Identifying covered asset acquisitions and relevant foreign
                assets to which paragraphs (b) and (c) of this section do not apply.
                For transactions occurring on or after January 1, 2011, and before July
                21, 2014, other than transactions occurring before July 21, 2014,
                resulting from an entity classification election made under Sec.
                301.7701-3 of this chapter that is filed on or after July 29, 2014, and
                that is effective on or before July 21, 2014, the transactions set
                forth under section
                [[Page 16252]]
                901(m)(2) are CAAs and the assets that are relevant foreign assets with
                respect to the CAA under section 901(m)(4) are RFAs.
                 (e) Examples. The following examples illustrate the rules of this
                section:
                 (1) Example 1: CAA involving an acquisition of a partnership
                interest for foreign income tax purposes--(i) Facts. (A) FPS is an
                entity organized in Country F that is treated as a partnership for
                both U.S. and Country F income tax purposes. FPS is owned equally by
                FC1 and FC2, each of which is a corporation organized in Country F
                and treated as a corporation for both U.S. and Country F income tax
                purposes. FPS has a single asset, Asset A. USP, a domestic
                corporation, owns all the interests in DE, a disregarded entity.
                 (B) Pursuant to the same transaction, USP acquires FC1's
                interest in FPS, and DE acquires FC2's interest in FPS. For U.S.
                income tax purposes, with respect to USP, the acquisition of the
                interests in FPS is treated as the acquisition of Asset A by USP.
                See Rev. Rul. 99-6, 1999-1 C.B. 432. For Country F tax purposes, the
                acquisitions of the interests of FPS by USP and DE are treated as
                acquisitions of partnership interests.
                 (ii) Result. The transaction is a CAA under paragraph (b)(4) of
                this section because it is treated as the acquisition of Asset A for
                U.S. income tax purposes and the acquisition of interests in a
                fiscally transparent entity for Country F tax purposes.
                 (2) Example 2: CAA involving an asset acquisition for purposes
                of both U.S. income tax and a foreign income tax--(i) Facts. (A)
                USP, a domestic corporation, wholly owns CFC1, a foreign
                corporation, and CFC1 wholly owns CFC2, also a foreign corporation.
                CFC1 and CFC2 are organized in Country F. CFC1 owns Asset A.
                 (B) In an exchange described in section 351, CFC1 transfers
                Asset A to CFC2 in exchange for CFC2 common stock and cash. CFC1
                recognizes gain on the exchange under section 351(b). Under section
                362(a), CFC2's U.S. basis in Asset A is increased by the gain
                recognized by CFC1. For Country F tax purposes, gain or loss is not
                recognized on the transfer of Asset A to CFC2, and therefore there
                is no increase in the foreign basis in Asset A.
                 (ii) Result. The transaction is a CAA under paragraph (b)(6) of
                this section because it is treated as an acquisition of Asset A by
                CFC2 for both U.S. and Country F income tax purposes, and it results
                in an increase in the U.S. basis of Asset A without a corresponding
                increase in the foreign basis of Asset A.
                 (3) Example 3: RFA status determined immediately after CAA;
                application of principal purpose rule--(i) Facts. (A) USP1 and USP2
                are unrelated domestic corporations. USP1 wholly owns USSub, also a
                domestic corporation. On January 1 of Year 1, USP2 acquires all of
                the stock of USSub from USP1 in a qualified stock purchase (as
                defined in section 338(d)(3)) to which section 338(a) applies.
                Immediately after the acquisition, none of the income, deduction,
                gain, or loss attributable to any of the assets of USSub is taken
                into account in determining foreign income for purposes of a foreign
                income tax nor would such items be taken into account in determining
                foreign income for purposes of a foreign income tax immediately
                after the acquisition if such assets were to give rise to income,
                deduction, gain, or loss immediately after the acquisition.
                 (B) On December 1 of Year 1, USSub contributes all its assets to
                FSub, its wholly owned subsidiary, which is a corporation for both
                U.S. and Country X income tax purposes, in a transfer described in
                section 351 (subsequent transfer). USSub recognizes no gain or loss
                for U.S. or Country X income tax purposes as a result of the
                subsequent transfer. As a result of the subsequent transfer, income,
                deduction, gain, or loss attributable to the assets of USSub that
                were transferred to FSub is taken into account in determining
                foreign income of FSub for Country X tax purposes.
                 (ii) Result. (A) Under paragraph (b)(1) of this section, the
                acquisition by USP2 of the stock of USSub is a section 338 CAA.
                Under paragraph (c)(1) of this section, none of the assets of USSub
                are RFAs immediately after the CAA, because none of the income,
                deduction, gain, or loss attributable to such assets is taken into
                account for purposes of determining foreign income with respect to
                any foreign income tax immediately after the CAA (nor would such
                items be taken into account for purposes of determining foreign
                income immediately after the CAA if such assets were to give rise to
                income, deduction, gain, or loss at such time).
                 (B) Although the subsequent transfer is not a CAA under
                paragraph (b) of this section, the subsequent transfer causes the
                assets of USSub to become relevant in the hands of FSub in
                determining foreign income for Country X tax purposes. Because the
                subsequent transfer occurred within the one-year period following
                the CAA, it is presumed to have a principal purpose of avoiding
                section 901(m) under paragraph (c)(3) of this section. Accordingly,
                the assets of USSub with respect to the CAA occurring on January 1
                of Year 1 become RFAs with respect to Country X tax as a result of
                the subsequent transfer. Thus, a basis difference with respect to
                Country X tax must be computed for the RFAs and taken into account
                under section 901(m).
                 (f) Applicability dates. (1) Except as provided in paragraph (f)(2)
                of this section, this section applies to CAAs occurring on or after
                March 23, 2020.
                 (2) Paragraphs (a), (b)(1) through (3), and (c)(1) of this section
                apply to transactions occurring on or after July 21, 2014, and to
                transactions occurring before that date resulting from an entity
                classification election made under Sec. 301.7701-3 of this chapter
                that is filed on or after July 29, 2014, and that is effective on or
                before July 21, 2014. Paragraph (d) of this section applies to
                transactions occurring on or after January 1, 2011, and before July 21,
                2014, other than transactions occurring before July 21, 2014, resulting
                from an entity classification election made under Sec. 301.7701-3 of
                this chapter that is filed on or after July 29, 2014, and that is
                effective on or before July 21, 2014.
                 (3) Taxpayers may, however, choose to apply provisions in this
                section before the date such provisions are applicable pursuant to
                paragraph (f)(1) or (2) of this section, provided that they (along with
                any persons that are related (within the meaning of section 267(b) or
                707(b)) to the taxpayer)--
                 (i) Consistently apply this section (excluding paragraph (d) of
                this section) to all CAAs occurring on or after December 7, 2016 and
                consistently apply Sec. 1.704-1(b)(4)(viii)(c)(4)(v) through (vii),
                Sec. 1.901(m)-1, and Sec. Sec. 1.901(m)-3 through 1.901(m)-8
                (excluding Sec. 1.901(m)-4(e)) to all CAAs occurring on or after
                January 1, 2011, on any original or amended tax return for each taxable
                year for which the application of the provisions listed in this
                paragraph (f)(3)(i) affects the tax liability and for which the statute
                of limitations does not preclude assessment or the filing of a claim
                for refund, as applicable;
                 (ii) File all tax returns described in paragraph (f)(3)(i) of this
                section for any taxable year ending on or before March 23, 2020, no
                later than March 23, 2021; and
                 (iii) Make appropriate adjustments to take into account
                deficiencies that would have resulted from the consistent application
                under paragraph (f)(3)(i) of this section for taxable years that are
                not open for assessment.

                0
                Par. 6. Section 1.901(m)-2T is removed.
                0
                Par. 7. Section 1.901(m)-3 is added to read as follows:
                Sec. 1.901(m)-3 Disqualified tax amount and aggregate basis
                difference carryover.
                 (a) In general. If a section 901(m) payor has an aggregate basis
                difference, with respect to a foreign income tax and a foreign payor,
                for a U.S. taxable year, the section 901(m) payor must determine the
                portion of a foreign income tax amount that is disqualified under
                section 901(m) (disqualified tax amount). Paragraph (b) of this section
                provides rules for determining the disqualified tax amount. Paragraph
                (c) of this section provides rules for determining what portion, if
                any, of aggregate basis difference will be carried forward to the next
                U.S. taxable year (aggregate basis difference carryover). Paragraph (d)
                of this section provides applicability dates.
                [[Page 16253]]
                 (b) Disqualified tax amount--(1) In general. A section 901(m)
                payor's disqualified tax amount is not taken into account in
                determining the credit allowed under section 901(a). If the section
                901(m) payor is an applicable foreign corporation, the disqualified tax
                amount is not taken into account for purposes of section 902 (for tax
                years of foreign corporations beginning before January 1, 2018) or 960.
                Sections 78 and 275 do not apply to the disqualified tax amount. The
                disqualified tax amount is allowed as a deduction to the extent
                otherwise deductible. See sections 164, 212, and 964 and the
                regulations under those sections.
                 (2) Determination of disqualified tax amount--(i) In general.
                Except as provided in paragraph (b)(2)(iv) of this section, the
                disqualified tax amount is equal to the lesser of the foreign income
                tax amount that is paid or accrued by, or considered paid or accrued
                by, the section 901(m) payor for the U.S. taxable year or the tentative
                disqualified tax amount. All calculations are determined with respect
                to each separate category.
                 (ii) Tentative disqualified tax amount. The tentative disqualified
                tax amount is equal to the amount determined under paragraph
                (b)(2)(ii)(A) of this section reduced (but not below zero) by the
                amount described in paragraph (b)(2)(ii)(B) of this section.
                 (A) The product of--
                 (1) The sum of the foreign income tax amount and the FCCTs that are
                paid or accrued by, or considered paid or accrued by, the section
                901(m) payor, and
                 (2) A fraction, the numerator of which is the aggregate basis
                difference, but not in excess of the allocable foreign income, and the
                denominator of which is the allocable foreign income.
                 (B) The amount of the FCCT that is a disqualified tax amount of the
                section 901(m) payor with respect to another foreign income tax.
                 (iii) Allocable foreign income--(A) No allocation required. Except
                as provided in paragraph (b)(2)(iii)(D) of this section, if the entire
                foreign income tax amount is paid or accrued by, or considered paid or
                accrued by, a single section 901(m) payor, then the allocable foreign
                income is equal to the entire foreign income, determined with respect
                to each separate category.
                 (B) Allocation required. Except as provided in paragraph
                (b)(2)(iii)(D) of this section, if the foreign income tax amount is
                allocated to, and considered paid or accrued by, more than one person,
                a section 901(m) payor's allocable foreign income is equal to the
                portion of the foreign income that relates to the foreign income tax
                amount allocated to that section 901(m) payor, determined with respect
                to each separate category.
                 (C) Rules for allocations. This paragraph (b)(2)(iii)(C) provides
                allocation rules that apply to determine allocable foreign income in
                certain cases.
                 (1) If the foreign payor is involved in a mid-year transaction and
                the foreign income tax amount is allocated under Sec. 1.336-
                2(g)(3)(ii), Sec. 1.338-9(d), or Sec. 1.901-2(f)(4), then, to the
                extent any portion of the foreign income tax amount is allocated to,
                and considered paid or accrued by, a section 901(m) payor, the
                allocable foreign income of the section 901(m) payor is determined in
                accordance with the principles of Sec. 1.1502-76(b). To the extent the
                foreign income tax amount is allocated to an entity that is a
                partnership for U.S. income tax purposes, a portion of the foreign
                income is first allocated to the partnership in accordance with the
                principles of Sec. 1.1502-76(b), which is then allocated under the
                rules of paragraph (b)(2)(iii)(C)(2) of this section to determine the
                allocable foreign income of a section 901(m) payor that owns an
                interest in the partnership directly or indirectly through one or more
                other partnerships for U.S. income tax purposes.
                 (2) If the foreign income tax amount is considered paid or accrued
                by a section 901(m) payor for a U.S. taxable year under Sec. 1.702-
                1(a)(6), the determination of the allocable foreign income must be
                consistent with the allocation of the foreign income tax amount that
                relates to the foreign income. See Sec. 1.704-1(b)(4)(viii).
                 (3) If the foreign income tax amount that is allocated to, and
                considered paid or accrued by, a section 901(m) payor for a U.S.
                taxable year is determined under Sec. 1.901-2(f)(3)(i), the allocable
                foreign income is determined in accordance with Sec. 1.901-
                2(f)(3)(iii).
                 (D) Failure to substantiate allocable foreign income. If, pursuant
                to section 901(m)(3)(A), a section 901(m) payor fails to substantiate
                its allocable foreign income to the satisfaction of the Secretary, then
                allocable foreign income will equal the amount determined by dividing
                the sum of the foreign income tax amount and the FCCTs that are paid or
                accrued by, or considered paid or accrued by, the section 901(m) payor,
                by the highest marginal tax rate applicable to income of the foreign
                payor under foreign tax law.
                 (iv) Special rule. A section 901(m) payor's disqualified tax amount
                is zero for a U.S. taxable year if:
                 (A) The section 901(m) payor's aggregate basis difference for the
                U.S. taxable year is a negative amount;
                 (B) Foreign income is less than or equal to zero for the foreign
                taxable year of the foreign payor; or
                 (C) The foreign income tax amount that is paid or accrued by, or
                considered paid or accrued by, the section 901(m) payor for the U.S.
                taxable year is zero.
                 (3) Examples. The following examples illustrate the rules of
                paragraph (b)(2) of this section. For purposes of all the examples,
                unless otherwise specified: USP is a domestic corporation. CFC1, CFC2,
                DE1, and DE2 are organized in Country F and are treated as corporations
                for Country F tax purposes. CFC1 and CFC2 are applicable foreign
                corporations. DE1 and DE2 are disregarded entities. USP, CFC1, and CFC2
                each have a calendar year for both U.S. and Country F income tax
                purposes, and DE1 and DE2 each have a calendar year for Country F tax
                purposes. Country F and Country G each impose a single tax that is a
                foreign income tax. CFC1, CFC2, DE1, and DE2 each have a functional
                currency of the u with respect to all activities. At all relevant
                times, 1u equals $1. All amounts are stated in millions. The examples
                assume that the applicable cost recovery method for property results in
                basis being recovered ratably over the life of the property beginning
                on the first day of the U.S. taxable year in which the property is
                acquired or placed into service; there is a single separate category
                with respect to a foreign income and foreign income tax amount; and a
                section 901(m) payor properly substantiates its allocable foreign
                income to the satisfaction of the Secretary.
                 (i) Example 1: Determining aggregate basis difference; multiple
                foreign payors--(A) Facts. CFC1 wholly owns CFC2 and DE1. DE1 wholly
                owns DE2. Assume that the tax laws of Country F do not allow
                combined income reporting or the filing of consolidated income tax
                returns. Accordingly, CFC1, CFC2, DE1, and DE2 file separate tax
                returns for Country F tax purposes. USP acquires all of the stock of
                CFC1 in a qualified stock purchase (as defined in section 338(d)(3))
                to which section 338(a) applies for both CFC1 and CFC2.
                 (B) Result. (1) The acquisition of CFC1 gives rise to four
                separate CAAs under Sec. 1.901(m)-2(b). The acquisition of the
                stock of CFC1 and the deemed purchase of the stock of CFC2 under
                section 338(h)(3)(B) are each a section 338 CAA under Sec.
                1.901(m)-2(b)(1). Furthermore, because the deemed purchase of the
                assets of DE1 and DE2 for U.S. income tax purposes is disregarded
                for Country F tax purposes, each acquisition is a CAA under Sec.
                1.901(m)-2(b)(2). Because these four CAAs occur pursuant to a plan,
                under Sec. 1.901(m)-1(a)(3) they are part of an
                [[Page 16254]]
                aggregated CAA transaction. Under Sec. 1.901(m)-1(a)(37), CFC1 is
                the RFA owner (U.S.) with respect to its assets and those of DE1 and
                DE2. CFC2 is the RFA owner (U.S.) with respect to its assets. Under
                Sec. 1.901(m)-1(a)(28), CFC1, CFC2, DE1, and DE2 are each a foreign
                payor for Country F tax purposes. Under Sec. 1.901(m)-1(a)(41),
                CFC1 is the section 901(m) payor with respect to foreign income tax
                amounts for which CFC1, DE1, and DE2 are the foreign payors (see
                Sec. 1.901-2(f)(1) and (f)(4)(ii)). CFC2 is the section 901(m)
                payor with respect to foreign income tax amounts for which CFC2 is
                the foreign payor (see Sec. 1.901-2(f)(1)).
                 (2) In determining aggregate basis difference under Sec.
                1.901(m)-1(a)(1) for a U.S. taxable year of CFC1, CFC1 has three
                computations with respect to Country F tax, because there are three
                foreign payors for Country F tax purposes whose foreign income tax
                amount, if any, is considered paid or accrued by CFC1 as the section
                901(m) payor. Furthermore, for each U.S. taxable year, CFC1 will
                compute a separate disqualified tax amount and aggregate basis
                difference carryover (if any) under paragraph (b)(2) of this
                section, with respect to each foreign payor.
                 (3) In determining aggregate basis difference for a U.S. taxable
                year of CFC2 under Sec. 1.901(m)-1(a)(1), CFC2 has a single
                computation with respect to Country F tax, because there is a single
                foreign payor (CFC2) for Country F tax purposes whose foreign income
                tax amount, if any, is considered paid or accrued by CFC2 as the
                section 901(m) payor. Furthermore, for each U.S. taxable year, CFC2
                will compute a disqualified tax amount and aggregate basis
                difference carryover (if any) under paragraph (b)(2) of this
                section.
                 (C) Alternative facts. Assume the same facts as in paragraph
                (b)(3)(i)(A) of this section (paragraph (A) of this Example 1),
                except that foreign income for Country F tax purposes is based on
                combined income (within the meaning of Sec. 1.901-2(f)(3)(ii)) of
                CFC1, CFC2, DE1, and DE2. For purposes of determining an aggregate
                basis difference for a U.S. taxable year of CFC1 under Sec.
                1.901(m)-1(a)(1), CFC1, DE1, and DE2 are treated as a single foreign
                payor because all of the items of income, deduction, gain, or loss
                with respect to CFC1, DE1, and DE2 are included in the earnings and
                profits of CFC1 for U.S. income tax purposes. For each U.S. taxable
                year, CFC1 will therefore compute a single aggregate basis
                difference, disqualified tax amount, and aggregate basis difference
                carryover. The result for CFC2 under the alternative facts is the
                same as in paragraph (b)(3)(i)(B)(3) (paragraph (B)(3) of this
                Example 1).
                 (ii) Example 2: Computation of disqualified tax amount--(A)
                Facts. On December 31 of Year 0, USP acquires all of the stock of
                CFC1 in a qualified stock purchase (as defined in section 338(d)(3))
                to which section 338(a) applies (Acquisition). CFC1 owns four assets
                (Asset A, Asset B, Asset C, and Asset D, and collectively, Assets)
                and conducts activities in Country F and in a Country G branch. The
                activities conducted by CFC1 in Country G are not subject to tax in
                Country F. The tax rate is 25% in Country F and 30% in Country G.
                For Country F tax purposes, CFC1's foreign income and foreign income
                tax amount for each foreign taxable year 1 through 15 is 100u and
                $25 (25u translated at the exchange rate of $1 = 1u), respectively.
                For Country G tax purposes, CFC1's foreign income and foreign income
                tax amount for each foreign taxable year 1 through 5 is 400u and
                $120 (120u translated at the exchange rate of $1 = 1u),
                respectively. No dispositions occur for any of the Assets during the
                applicable cost recovery period. Additional facts relevant to each
                of the Assets are summarized below.
                
                --------------------------------------------------------------------------------------------------------------------------------------------------------
                 Applicable cost
                 Assets Relevant foreign income Basis recovery period Cost recovery amount
                 tax difference (years)
                --------------------------------------------------------------------------------------------------------------------------------------------------------
                Asset A............................... Country F tax............ 150u 15 10u (150u/15).
                Asset B............................... Country F tax............ 50u 5 10u (50u/5).
                Asset C............................... Country G tax............ 300u 5 60u (300u/5).
                Asset D............................... Country G tax............ (100u) 5 negative 20u (negative 100/5).
                --------------------------------------------------------------------------------------------------------------------------------------------------------
                 (B) Result. (1) Under Sec. 1.901(m)-2(b)(1), the acquisition of
                the stock of CFC1 is a section 338 CAA. Under Sec. 1.901(m)-
                2(c)(1), Assets A and B are RFAs with respect to Country F tax,
                because they are relevant in determining foreign income of CFC1 for
                Country F tax purposes and were owned by CFC1 when the Acquisition
                occurred. Assets C and D are RFAs with respect to Country G tax,
                because they are relevant in determining foreign income of CFC1 for
                Country G tax purposes and were owned by CFC1 when the Acquisition
                occurred. Under Sec. 1.901(m)-1(a)(37), CFC1 is the RFA owner
                (U.S.) with respect to all of the RFAs. Under Sec. 1.901(m)-
                1(a)(41) and (28), CFC1 is the section 901(m) payor and the foreign
                payor for Country F and Country G tax purposes.
                 (2) In determining aggregate basis difference for a U.S. taxable
                year of CFC1, CFC1 has two computations, one with respect to Country
                F tax and one with respect to Country G tax. Under Sec. 1.901(m)-
                1(a)(1), the aggregate basis difference for a U.S. taxable year with
                respect to Country F tax is equal to the sum of the allocated basis
                differences and allocated basis difference adjustments with respect
                to Assets A and B for the U.S. taxable year. Under Sec. 1.901(m)-
                1(a)(5), allocated basis differences are the sum of cost recovery
                amounts and disposition amounts. Because there are no dispositions,
                the only allocated basis differences taken into account in
                determining an aggregate basis difference are cost recovery amounts.
                Under Sec. 1.901(m)-5(b), any cost recovery amounts are attributed
                to CFC1, because CFC1 is the section 901(m) payor and RFA owner
                (U.S.) with respect to all of the Assets. For each U.S. taxable
                year, CFC1 will compute a separate disqualified tax amount and
                aggregate basis difference carryover (if any) with respect to
                Country F tax and Country G tax under paragraph (b)(2) of this
                section. For purposes of both disqualified tax amount computations,
                because CFC1 is the section 901(m) payor and foreign payor, the
                foreign income tax amount paid or accrued by CFC1 with respect to
                Country F tax and Country G tax, respectively, will be the entire
                foreign income tax amount and CFC1's allocable foreign income will
                be the entire foreign income.
                 (3) With respect to Country F tax, in U.S. taxable years 1
                through 5, CFC1 has an aggregate basis difference of 20u each year
                (10u cost recovery amount with respect to Asset A plus 10u cost
                recovery amount with respect to Asset B). For U.S. taxable years 1
                through 5, under paragraph (b)(2) of this section, the disqualified
                tax amount each year is $5, the lesser of two amounts: the tentative
                disqualified tax amount, in this case, $5 ($25 foreign income tax
                amount x (20u aggregate basis difference/100u allocable foreign
                income)), or the foreign income tax amount paid or accrued by CFC1,
                in this case, $25. After U.S. taxable year 5, Asset B has no
                unallocated basis difference with respect to Country F tax.
                Accordingly, in U.S. taxable years 6 through 15, CFC1 has an
                aggregate basis difference of 10u each year. Accordingly, for U.S.
                taxable years 6 through 15, the disqualified tax amount each year is
                $2.50, the lesser of two amounts: the tentative disqualified tax
                amount, in this case, $2.50 ($25 foreign income tax amount x (10u
                aggregate basis difference/100u allocable foreign income)), or the
                foreign income tax amount paid or accrued by CFC1, in this case,
                $25. After U.S. taxable year 15, Asset A has no unallocated basis
                difference with respect to Country F tax and, therefore, CFC1 has no
                disqualified tax amount with respect to Country F Tax.
                 (4) With respect to Country G tax, in U.S. taxable years 1
                through 5, CFC1 has an aggregate basis difference of 40u each year
                (60u cost recovery amount with respect to Asset C + (20u) cost
                recovery amount with respect to Asset D). For U.S. taxable years 1
                through 5, under paragraph (b)(2) of this
                [[Page 16255]]
                section, the disqualified tax amount each year is $12, the lesser of
                two amounts: the tentative disqualified tax amount, in this case,
                $12 ($120 foreign income tax amount x (40u aggregate basis
                difference/400u allocable foreign income)), or the foreign income
                tax amount paid or accrued by CFC1, in this case, $120. After U.S.
                taxable year 5, Asset C and Asset D have no unallocated basis
                difference with respect to Country G tax. Accordingly, in U.S.
                taxable years 6 through 15, CFC1 has no disqualified tax amount with
                respect to Country G Tax.
                 (iii) Example 3: FCCT--(A) Facts. In U.S. taxable year 1, USP
                acquires all of the interests in DE1 in a transaction (Transaction)
                that is treated as a stock acquisition for Country F tax purposes.
                Immediately after the Transaction, DE1 owns assets (Pre-Transaction
                Assets), all of which are used in a Country G branch and give rise
                to income that is taken into account for Country F tax and Country G
                tax purposes. After the Transaction, DE1 acquires additional assets
                (Post-Transaction Assets), which are not used by the Country G
                branch. Both Country F and Country G have a tax rate of 30%. Country
                F imposes worldwide tax on its residents and provides a foreign tax
                credit for taxes paid to other jurisdictions. In foreign taxable
                year 3, 100u of income is attributable to DE1's Post-Transaction
                Assets and 100u of income is attributable to DE1's Pre-Transaction
                Assets. For Country G tax purposes, the foreign income is 100u and
                foreign income tax amount is 30u (30% x 100u). For Country F tax
                purposes, the foreign income is 200u and the pre-foreign tax credit
                tax is 60u (30% x 200u). The 60u of Country F pre-foreign tax credit
                tax is reduced by the 30u foreign income tax amount imposed for
                Country G tax purposes. Thus, the foreign income tax amount for
                Country F tax purposes is $30 (30u translated into dollars at the
                exchange rate of $1 = 1u). Assume that for U.S. taxable year 3 USP
                has 100u aggregate basis difference with respect to Country F tax
                and 100u aggregate basis difference with respect to Country G tax.
                USP does not dispose of DE1 or any assets of DE1 in U.S. taxable
                year 3.
                 (B) Result. (1) Under Sec. 1.901(m)-2(b)(2), the Transaction is
                a CAA. Under Sec. 1.901(m)-2(c)(1), the Pre-Transaction Assets are
                RFAs with respect to both Country F tax and Country G tax, because
                they are relevant in determining the foreign income of DE1 for
                Country F tax and Country G tax purposes and were owned by DE1 when
                the Transaction occurred. Under Sec. 1.901(m)-1(a)(37), USP is the
                RFA owner (U.S.) with respect to the RFAs. Under Sec. 1.901(m)-
                1(a)(28), DE1 is a foreign payor for Country F tax and Country G tax
                purposes. Under Sec. 1.901(m)-1(a)(41), USP is the section 901(m)
                payor with respect to foreign income tax amounts for which DE1 is
                the foreign payor (see Sec. 1.901-2(f)(4)(ii)). Because the Country
                G foreign income tax amount is claimed as a credit for purposes of
                determining the Country F foreign income tax amount, the Country G
                foreign income tax amount is an FCCT under Sec. 1.901(m)-1(a)(22).
                 (2) Under Sec. 1.901(m)-1(a)(1), for each U.S. taxable year,
                USP will separately compute the aggregate basis difference with
                respect to Country F tax and with respect to Country G tax and will
                use those amounts to separately compute a disqualified tax amount
                and aggregate basis difference carryover (if any) with respect to
                each foreign income tax. Because DE1 is a disregarded entity owned
                by USP during the entire U.S. taxable year 3, the foreign income tax
                amount paid or accrued by DE1 is not subject to allocation.
                Accordingly, for purposes of each of the disqualified tax amount
                computations, the foreign income tax amount paid or accrued by USP
                with respect to Country F tax and Country G tax, respectively, is
                the entire foreign income tax amount paid or accrued by DE1, and,
                under paragraph (b)(2)(iii)(A) of this section, USP's allocable
                foreign income will be equal to DE1's entire foreign income.
                 (3) As stated in paragraph (b)(3)(iii)(A) of this section
                (paragraph (A) of this Example 3), for U.S. taxable year 3 USP has
                100u aggregate basis difference with respect to Country F tax and
                100u aggregate basis difference with respect to Country G tax. With
                respect to Country G tax, in U.S. taxable year 3, under paragraph
                (b)(2) of this section, the disqualified tax amount is $30, the
                lesser of the two amounts: the tentative disqualified tax amount, in
                this case, $30 ($30 foreign income tax amount x (100u aggregate
                basis difference/100u allocable foreign income)), or the foreign
                income tax amount considered paid or accrued by USP, in this case,
                $30.
                 (4) With respect to Country F tax, in U.S. taxable year 3, under
                paragraph (b)(2) of this section, the disqualified tax amount is $0,
                the lesser of two amounts: the tentative disqualified tax amount, in
                this case $0 (($30 foreign income tax amount + $30 Country G FCCT) x
                (100u aggregate basis difference/200u foreign income) = $30 reduced
                by $30 Country G FCCT that is a disqualified tax amount of USP), or
                the foreign income tax amount considered paid or accrued by USP, in
                this case, $30.
                 (c) Aggregate basis difference carryover--(1) In general. If a
                section 901(m) payor has an aggregate basis difference carryover for a
                U.S. taxable year, as determined under this paragraph (c), the
                aggregate basis difference carryover is taken into account in computing
                the section 901(m) payor's aggregate basis difference for the next U.S.
                taxable year. For successor rules that apply to an aggregate basis
                difference carryover, see Sec. 1.901(m)-6(c).
                 (2) Amount of aggregate basis difference carryover. (i) If a
                section 901(m) payor's disqualified tax amount is zero, all of the
                section 901(m) payor's aggregate basis difference (positive or
                negative) for the U.S. taxable year gives rise to an aggregate basis
                difference carryover to the next U.S. taxable year.
                 (ii) If a section 901(m) payor's disqualified tax amount is not
                zero, then aggregate basis difference carryover can arise in either or
                both of the following two situations:
                 (A) If a section 901(m) payor's aggregate basis difference for the
                U.S. taxable year exceeds its allocable foreign income, the excess
                gives rise to an aggregate basis difference carryover.
                 (B) If the tentative disqualified tax amount exceeds the
                disqualified tax amount, the excess tentative disqualified tax amount
                is converted into aggregate basis difference carryover by multiplying
                such excess by a fraction, the numerator of which is the allocable
                foreign income, and the denominator of which is the sum of the foreign
                income tax amount and the FCCTs that are paid or accrued by, or
                considered paid or accrued by, the section 901(m) payor.
                 (3) Example. The following example illustrates the rules of
                paragraph (c) of this section.
                 (i) Facts. (A) On July 1 of Year 1, CFC1 acquires all of the
                interests of DE1 in a transaction (Transaction) that is treated as a
                stock acquisition for Country F tax purposes. CFC1 and DE1 are
                organized in Country F and are treated as corporations for Country F
                tax purposes. CFC1 is an applicable foreign corporation, and DE1 is
                a disregarded entity. CFC1 has a calendar year for U.S. income tax
                purposes, and DE1 has a June 30 year-end for Country F tax purposes.
                Country F imposes a single tax that is a foreign income tax. CFC1
                and DE1 each have a functional currency of the u with respect to all
                activities. Immediately after the Transaction, DE1 owns one asset,
                Asset A, that gives rise to income that is taken into account for
                Country F tax purposes. For the first U.S. taxable year (U.S.
                taxable year 1) there is a cost recovery amount with respect to
                Asset A of 9u, and for each subsequent U.S. taxable year until the
                U.S. basis is fully recovered, there is a cost recovery amount with
                respect to Asset A of 18u. There is no disposition of Asset A.
                 (ii) Result. (A) Under Sec. 1.901(m)-2(b)(2), the Transaction
                is a CAA. Under Sec. 1.901(m)-2(c)(1), Asset A is an RFA with
                respect to Country F tax because it is relevant in determining the
                foreign income of DE1 for Country F tax purposes and was owned by
                DE1 when the Transaction occurred. Under Sec. 1.901(m)-1(a)(37),
                CFC1 is the RFA owner (U.S.) with respect to Asset A. Under Sec.
                1.901(m)-1(a)(28), DE1 is a foreign payor for Country F tax
                purposes. Under Sec. 1.901(m)-1(a)(41), CFC1 is the section 901(m)
                payor with respect to foreign income tax amounts for which DE1 is
                the foreign payor (see Sec. 1.901-2(f)(4)(ii)).
                 (B) Under Sec. 1.901(m)-1(a)(1), in determining the aggregate
                basis difference for U.S. taxable year 1, CFC1 has one computation
                with respect to Country F tax. Under Sec. 1.901(m)-1(a)(1),
                aggregate basis difference with respect to Country F tax is equal to
                the sum of allocated basis differences and allocated basis
                difference adjustments with respect to all RFAs, which, in this
                case, is only Asset A. Under Sec. 1.901(m)-1(a)(5), allocated basis
                differences are the sum of cost recovery amounts and disposition
                amounts. Because there is no
                [[Page 16256]]
                disposition of Asset A, the only allocated basis difference taken
                into account in determining an aggregate basis difference are cost
                recovery amounts with respect to Asset A. Under Sec. 1.901(m)-5(b),
                any cost recovery amounts are assigned to a U.S taxable year of
                CFC1, because CFC1 is the section 901(m) payor and RFA owner (U.S.)
                with respect to Asset A. Under paragraph (b)(2) of this section, for
                each U.S. taxable year, CFC1 will compute a disqualified tax amount
                and aggregate basis difference carryover with respect to the
                aggregate basis difference. Because DE1 is a disregarded entity
                owned by CFC1, the foreign income tax amount paid or accrued by DE1
                is not subject to allocation. Accordingly, for purposes of the
                disqualified tax amount computation, the foreign income tax amount
                paid or accrued by CFC1 with respect to Country F tax is the entire
                foreign income tax amount paid or accrued by DE1, and under
                paragraph (b)(2)(iii)(A) of this section, CFC1's allocable foreign
                income will be equal to DE1's entire foreign income.
                 (C) In U.S. taxable year 1, CFC1 has an aggregate basis
                difference of 9u (the 9u cost recovery amount with respect to Asset
                A for U.S. taxable year 1). However, because the foreign taxable
                year of DE1, the foreign payor, will not end between July 1 and
                December 31, there will not be a foreign income tax amount for U.S.
                taxable year 1. Because the foreign income tax amount considered
                paid or accrued by CFC1 for U.S. taxable year 1 is zero, under
                paragraph (b)(2)(iv) of this section, the disqualified tax amount
                for U.S. taxable year 1 of CFC1 is also zero. Furthermore, because
                the disqualified tax amount is zero, under paragraph (c)(2)(i) of
                this section, CFC1 has an aggregate basis difference carryover equal
                to 9u, the entire amount of the aggregate basis difference for U.S.
                taxable year 1. Under paragraph (c)(1) of this section, the 9u
                aggregate basis difference carryover is taken into account in
                computing CFC1's aggregate basis difference for U.S. taxable year 2.
                Accordingly, in U.S. taxable year 2, CFC1 has an aggregate basis
                difference of 27u (18u cost recovery amount for U.S. taxable year 2,
                plus 9u aggregate basis difference carryover from U.S. taxable year
                1).
                 (d) Applicability dates. This section applies to CAAs occurring on
                or after March 23, 2020. Taxpayers may, however, choose to apply this
                section before the date this section is applicable provided that they
                (along with any persons that are related (within the meaning of section
                267(b) or 707(b)) to the taxpayer)--
                 (1) Consistently apply this section, Sec. 1.704-
                1(b)(4)(viii)(c)(4)(v) through (vii), Sec. 1.901(m)-1, and Sec. Sec.
                1.901(m)-4 through 1.901(m)-8 (excluding Sec. 1.901(m)-4(e)) to all
                CAAs occurring on or after January 1, 2011, and consistently apply
                Sec. 1.901(m)-2 (excluding Sec. 1.901(m)-2(d)) to all CAAs occurring
                on or after December 7, 2016, on any original or amended tax return for
                each taxable year for which the application of the provisions listed in
                this paragraph (d)(1) affects the tax liability and for which the
                statute of limitations does not preclude assessment or the filing of a
                claim for refund, as applicable
                 (2) File all tax returns described in paragraph (d)(1) of this
                section for any taxable year ending on or before March 23, 2020, no
                later than March 23, 2021; and
                 (3) Make appropriate adjustments to take into account deficiencies
                that would have resulted from the consistent application under
                paragraph (d)(1) of this section for taxable years that are not open
                for assessment.

                0
                Par. 9. Section 1.901(m)-4 is added to read as follows:
                Sec. 1.901(m)-4 Determination of basis difference.
                 (a) In general. This section provides rules for determining for
                each RFA the basis difference that arises as a result of a CAA. A basis
                difference is computed separately with respect to each foreign income
                tax for which an asset subject to a CAA is an RFA. Paragraph (b) of
                this section provides the general rule for determining basis difference
                that references only U.S. basis in the RFA. Paragraph (c) of this
                section provides for an election to determine basis difference by
                reference to foreign basis and sets forth the procedures for making the
                election. Paragraph (d) of this section provides special rules for
                determining basis difference in the case of a section 743(b) CAA.
                Paragraph (e) of this section provides a special rule for determining
                basis difference in an RFA with respect to a CAA to which paragraphs
                (b) through (d) of this section do not apply. Paragraph (f) of this
                section provides examples illustrating the rules of this section, and
                paragraph (g) of this section provides applicability dates.
                 (b) General rule. Except as otherwise provided in paragraphs (c),
                (d), and (e) of this section, basis difference is the U.S. basis in the
                RFA immediately after the CAA, less the U.S. basis in the RFA
                immediately before the CAA. Basis difference is an attribute that
                attaches to an RFA.
                 (c) Foreign basis election. (1) An election (foreign basis
                election) may be made to apply section 901(m)(3)(C)(i)(II) by reference
                to the foreign basis immediately after the CAA instead of the U.S.
                basis immediately before the CAA. Accordingly, if a foreign basis
                election is made, basis difference is the U.S. basis in the RFA
                immediately after the CAA, less the foreign basis in the RFA
                immediately after the CAA. For this purpose, the foreign basis
                immediately after the CAA takes into account any adjustment to that
                foreign basis resulting from the CAA for purposes of the foreign income
                tax.
                 (2) Except as otherwise provided in this paragraph (c), a foreign
                basis election is made by the RFA owner (U.S.). If, however, the RFA
                owner (U.S.) is a partnership, each partner in the partnership (and not
                the partnership) may independently make a foreign basis election. In
                the case of one or more tiered partnerships, the foreign basis election
                is made at the level at which a partner is not also a partnership.
                 (3) The foreign basis election may be made separately for each CAA,
                and with respect to each foreign income tax and each foreign payor. For
                purposes of making the foreign basis election, all CAAs that are part
                of an aggregated CAA transaction are treated as a single CAA.
                Furthermore, for purposes of making the foreign basis election, if
                foreign law imposes tax on the combined income (within the meaning of
                Sec. 1.901-2(f)(3)(ii)) of two or more foreign payors, all foreign
                payors whose items of income, deduction, gain, or loss for U.S. income
                tax purposes are included in the U.S. taxable income or earnings and
                profits of a single section 901(m) payor are treated as a single
                foreign payor.
                 (4) A foreign basis election is made by using foreign basis to
                determine basis difference for purposes of computing a disqualified tax
                amount and an aggregate basis difference carryover for the U.S. taxable
                year, as provided under Sec. 1.901(m)-3. A separate statement or form
                evidencing the foreign basis election need not be filed. Except as
                provided in paragraphs (c)(5) and (6) of this section, in order for a
                foreign basis election to be effective, the election must be reflected
                on a timely filed original federal income tax return (taking into
                account extensions) for the first U.S. taxable year that the foreign
                basis election is relevant to the computation of any amounts reported
                on such return, including on any required schedules.
                 (5) If the RFA owner (U.S.) is a partnership, a foreign basis
                election reflected on a partner's timely filed amended federal income
                tax return is also effective if all of the following conditions are
                satisfied:
                 (i) The partner's timely filed original federal income tax return
                (taking into account extensions) for the first U.S. taxable year of the
                partner in which a foreign basis election is relevant to the
                computation of any amounts reported
                [[Page 16257]]
                on such return, including on any required schedules, does not reflect
                the application of section 901(m);
                 (ii) The information provided by the partnership to the partner for
                purposes of applying section 901(m) and any information required to be
                reported by the partnership is based solely on computations that use
                foreign basis to determine basis difference; and
                 (iii) Before the due date of the original federal income tax return
                described in paragraph (c)(5)(i) of this section, the partner delegated
                the authority to the partnership to choose whether to provide the
                partner with information to apply section 901(m) using foreign basis,
                either pursuant to a written partnership agreement (within the meaning
                of Sec. 1.704-1(b)(2)(ii)(h)) or written notice provided by the
                partner to the partnership.
                 (6) If, pursuant to paragraph (g)(3) of this section, a taxpayer
                chooses to have this section apply to CAAs occurring on or after
                January 1, 2011, a foreign basis election will be effective if the
                election is reflected on a timely filed amended federal income tax
                return (or tax returns, as applicable) filed no later than March 23,
                2021.
                 (7) The foreign basis election is irrevocable. Relief under Sec.
                301.9100-1 is not available for the foreign basis election.
                 (d) Determination of basis difference in a section 743(b) CAA--(1)
                In general. Except as provided in paragraphs (d)(2) and (e) of this
                section, if there is a section 743(b) CAA, basis difference is the
                resulting basis adjustment under section 743(b) that is allocated to
                the RFA under section 755.
                 (2) Foreign basis election. If a foreign basis election is made
                with respect to a section 743(b) CAA, then, for purposes of paragraph
                (d)(1) of this section, the section 743(b) adjustment is determined by
                reference to the foreign basis of the RFA, determined immediately after
                the CAA.
                 (e) Determination of basis difference in an RFA with respect to a
                CAA with respect to which paragraphs (b), (c), and (d) of this section
                do not apply. For CAAs occurring on or after January 1, 2011, and
                before July 21, 2014, other than CAAs occurring before July 21, 2014,
                resulting from an entity classification election made under Sec.
                301.7701-3 of this chapter that is filed on or after July 29, 2014, and
                that is effective on or before July 21, 2014, basis difference in an
                RFA with respect to the CAA is the amount of any basis difference
                (within the meaning of section 901(m)(3)(C)(i)) that had not been taken
                into account under section 901(m)(3)(B) either as of July 21, 2014, or,
                in the case of an entity classification election made under Sec.
                301.7701-3 of this chapter that is filed on or after July 29, 2014, and
                that is effective on or before July 21, 2014, before the transactions
                that are deemed to occur under Sec. 301.7701-3(g) as a result of the
                change in classification.
                 (f) Examples. The following examples illustrate the rules of this
                section:
                 (1) Example 1: Scope of basis choice; identifying separate CAAs,
                RFA owners (U.S.), and foreign payors in an aggregated CAA
                transaction--(i) Facts. CFC1 wholly owns CFC2, both of which are
                applicable foreign corporations, organized in Country F, and treated
                as corporations for Country F tax purposes. CFC1 also wholly owns
                DE1, and DE1 wholly owns DE2. DE1 and DE2 are entities organized in
                Country F treated as corporations for Country F tax purposes and as
                disregarded entities for U.S. income tax purposes. Country F imposes
                a single tax that is a foreign income tax. All of the stock of CFC1
                is acquired in a qualified stock purchase (within the meaning of
                section 338(d)(3)) to which section 338(a) applies for both CFC1 and
                CFC2. For Country F tax purposes, the transaction is treated as an
                acquisition of the stock of CFC1.
                 (ii) Result. (A) The acquisition of CFC1 gives rise to four
                separate CAAs described in Sec. 1.901(m)-2. Under Sec. 1.901(m)-
                2(b)(1), the acquisition of the stock of CFC1 and the deemed
                acquisition of the stock of CFC2 under section 338(h)(3)(B) are each
                a section 338 CAA. Furthermore, because the deemed acquisition of
                the assets of each of DE1 and DE2 for U.S. income tax purposes is
                disregarded for Country F tax purposes, the deemed acquisitions are
                CAAs under Sec. 1.901(m)-2(b)(2). Because the four CAAs occurred
                pursuant to a plan, under Sec. 1.901(m)-1(a)(3), all of the CAAs
                are part of an aggregated CAA transaction. Under Sec. 1.901(m)-
                1(a)(37), CFC1 is the RFA owner (U.S.) with respect to its assets
                and the assets of DE1 and DE2 that are RFAs. CFC2 is the RFA owner
                (U.S.) with respect to its assets that are RFAs. Under Sec.
                1.901(m)-1(a)(28), CFC1, CFC2, DE1, and DE2 are each a foreign payor
                for Country F tax purposes.
                 (B) Under paragraph (c) of this section, a foreign basis
                election may be made by the RFA owner (U.S.). The election is made
                separately with respect to each CAA (for this purpose, treating all
                CAAs that are part of an aggregated CAA transaction as a single CAA)
                and with respect to each foreign income tax and foreign payor. Thus,
                in this case, CFC1 can make a separate foreign basis election for
                one or more of the following three groups of RFAs: RFAs that are
                relevant in determining foreign income of CFC1; RFAs that are
                relevant in determining foreign income of DE1; and RFAs that are
                relevant in determining foreign income of DE2. Furthermore, CFC2 can
                make a foreign basis election for all of its RFAs that are relevant
                in determining its foreign income.
                 (2) Example 2: Scope of basis choice; RFA owner (U.S.) is a
                partnership--(i) Facts. USPS is a domestic partnership for which a
                section 754 election is in effect. USPS owns two assets, the stock
                of DE1 and DE2. DE1 is an entity organized in Country X and treated
                as a corporation for Country X tax purposes. DE2 is an entity
                organized in Country Y and treated as a corporation for Country Y
                tax purposes. DE1 and DE2 are disregarded entities. Country X and
                Country Y each impose a single tax that is a foreign income tax. US1
                and US2, unrelated domestic corporations, and FP, a foreign person
                unrelated to US1 and US2, acquire partnership interests in USPS from
                existing partners of USPS pursuant to the same plan.
                 (ii) Result. Under Sec. 1.901(m)-2(b)(3), the acquisitions of
                the partnership interests in USPS by US1, US2, and FP each give rise
                to separate section 743(b) CAAs, but under Sec. 1.901(m)-1(a)(3),
                they are treated as an aggregated CAA transaction because they occur
                as part of a plan. Under Sec. 1.901(m)-1(a)(37), USPS is the RFA
                owner (U.S.) with respect to the assets of DE1 and DE2 that are
                RFAs. Under Sec. 1.901(m)-1(a)(28), DE1 is a foreign payor for
                Country X tax purposes, and DE2 is a foreign payor for Country Y tax
                purposes. Because the RFA owner (U.S.) is a partnership, paragraph
                (c)(2) of this section provides that US1, US2, and FP (the relevant
                partners in USPS) separately choose whether to make a foreign basis
                election for purposes of determining basis difference. Furthermore,
                under paragraph (c)(3) of this section, the choice to make the
                election is made separately by each partner with respect to each
                foreign payor. Thus, in this case, each partner may make separate
                elections for the RFAs that are relevant in determining foreign
                income of DE1 for Country X tax purposes and the RFAs that are
                relevant in determining foreign income of DE2 for Country Y tax
                purposes.
                 (g) Applicability dates. (1) Except as provided in paragraph (g)(2)
                of this section, this section applies to CAAs occurring on or after
                March 23, 2020.
                 (2) Paragraphs (a), (b), and (d)(1) of this section apply to CAAs
                occurring on or after July 21, 2014, and to CAAs occurring before that
                date resulting from an entity classification election made under Sec.
                301.7701-3 that is filed on or after July 29, 2014, and that is
                effective on or before July 21, 2014. Paragraph (e) of this section
                applies to CAAs occurring on or after January 1, 2011, and before July
                21, 2014, other than CAAs occurring before July 21, 2014, resulting
                from an entity classification election made under Sec. 301.7701-3 of
                this chapter that is filed on or after July 29, 2014, and that is
                effective on or before July 21, 2014. Taxpayers may, however,
                consistently apply paragraph (d)(1) of this section to all section
                743(b) CAAs occurring on or after January 1, 2011. For this purpose,
                persons that are related (within the meaning of section 267(b) or
                707(b)) will be treated as a single taxpayer.
                 (3) Taxpayers may, however, choose to apply provisions in this
                section before the date such provisions are applicable pursuant to
                paragraph (g)(1)
                [[Page 16258]]
                or (2) of this section, provided that they (along with any persons that
                are related (within the meaning of section 267(b) or 707(b)) to the
                taxpayer)--
                 (i) Consistently apply this section (excluding paragraph (e) of
                this section), Sec. 1.704-1(b)(4)(viii)(c)(4)(v) through (vii), Sec.
                1.901(m)-1, Sec. 1.901(m)-3, and Sec. Sec. 1.901(m)-5 through
                1.901(m)-8 to all CAAs occurring on or after January 1, 2011, and
                consistently apply Sec. 1.901(m)-2 (excluding Sec. 1.901(m)-2(d)) to
                all CAAs occurring on or after December 7, 2016, on any original or
                amended tax return for each taxable year for which the application of
                the provisions listed in this paragraph (g)(3)(i) affects the tax
                liability and for which the statute of limitations does not preclude
                assessment or the filing of a claim for refund, as applicable;
                 (ii) File all tax returns described in paragraph (g)(3)(i) of this
                section for any taxable year ending on or before March 23, 2020, no
                later than March 23, 2021; and
                 (iii) Make appropriate adjustments to take into account
                deficiencies that would have resulted from the consistent application
                under paragraph (g)(3)(i) of this section for taxable years that are
                not open for assessment.

                0
                Par. 10. Section 1.901(m)-4T is removed.
                0
                Par. 11. Section 1.901(m)-5 is added to read as follows:
                Sec. 1.901(m)-5 Basis difference taken into account.
                 (a) In general. This section provides rules for determining the
                amount of basis difference with respect to an RFA that is taken into
                account in a U.S. taxable year for purposes of determining the
                disqualified portion of a foreign income tax amount. Paragraph (b) of
                this section provides rules for determining a cost recovery amount and
                assigning that amount to a U.S. taxable year of a single section 901(m)
                payor when the RFA owner (U.S.) is the section 901(m) payor. Paragraph
                (c) of this section provides rules for determining a disposition amount
                and assigning that amount to a U.S. taxable year of a single section
                901(m) payor when the RFA owner (U.S.) is the section 901(m) payor.
                Paragraph (d) of this section provides rules for allocating cost
                recovery amounts and disposition amounts when the RFA owner (U.S.) is a
                fiscally transparent entity for U.S. income tax purposes. Paragraph (e)
                of this section provides special rules for allocating cost recovery
                amounts and disposition amounts with respect to certain section 743(b)
                CAAs. Paragraph (f) of this section provides special rules for
                allocating certain disposition amounts when a foreign payor is
                transferred in a mid-year transaction. Paragraph (g) of this section
                provides special rules for allocating both cost recovery amounts and
                disposition amounts in certain cases in which the RFA owner (U.S.)
                either is a reverse hybrid or a fiscally transparent entity for both
                U.S. and foreign income tax purposes that is directly or indirectly
                owned by a reverse hybrid. Paragraph (h) of this section provides
                examples illustrating the application of this section. Paragraph (i) of
                this section provides the applicability dates.
                 (b) Basis difference taken into account under applicable cost
                recovery method--(1) In general. When the RFA owner (U.S.) is a section
                901(m) payor, all of a cost recovery amount is attributed to the
                section 901(m) payor and assigned to the U.S. taxable year of the
                section 901(m) payor in which the corresponding U.S. basis deduction is
                taken into account under the applicable cost recovery method. This is
                the case regardless of whether the deduction is deferred or disallowed
                for U.S. income tax purposes. If instead the RFA owner (U.S.) is a
                fiscally transparent entity for U.S. income tax purposes, a cost
                recovery amount is allocated to one or more section 901(m) payors under
                paragraph (d) of this section, except as provided in paragraphs (e) and
                (g) of this section. If a cost recovery amount arises from an RFA with
                respect to a section 743(b) CAA, in certain cases the cost recovery
                amount is allocated to a section 901(m) payor under paragraph (e) of
                this section. In certain cases in which the RFA owner (U.S.) either is
                a reverse hybrid or a fiscally transparent entity for both U.S. and
                foreign income tax purposes that is directly or indirectly owned by a
                reverse hybrid, a cost recovery amount is allocated to one or more
                section 901(m) payors under paragraph (g) of this section.
                 (2) Determining a cost recovery amount--(i) General rule. A cost
                recovery amount for an RFA is determined by applying the applicable
                cost recovery method to the basis difference rather than to the U.S.
                basis.
                 (ii) U.S. basis subject to multiple cost recovery methods. If the
                entire U.S. basis is not subject to the same cost recovery method, the
                applicable cost recovery method for determining the cost recovery
                amount is the cost recovery method that applies to the portion of the
                U.S. basis that corresponds to the basis difference.
                 (3) Applicable cost recovery method. For purposes of section
                901(m), an applicable cost recovery method includes any method for
                recovering the cost of property over time for U.S. income tax purposes
                (each application of a method giving rise to a U.S. basis deduction).
                Such methods include depreciation, amortization, or depletion, as well
                as a method that allows the cost (or a portion of the cost) of property
                to be expensed in the year of acquisition or in the placed-in-service
                year, such as under section 179. Applicable cost recovery methods do
                not include any provision allowing the U.S. basis to be recovered upon
                a disposition of an RFA.
                 (c) Basis difference taken into account as a result of a
                disposition--(1) In general. Except as provided in paragraph (f) of
                this section, when the RFA owner (U.S.) is a section 901(m) payor, all
                of a disposition amount is attributed to the section 901(m) payor and
                assigned to the U.S. taxable year of the section 901(m) payor in which
                the disposition occurs. If instead the RFA owner (U.S.) is a fiscally
                transparent entity for U.S. income tax purposes, except as provided in
                paragraphs (e), (f), and (g) of this section, a disposition amount is
                allocated to one or more section 901(m) payors under paragraph (d) of
                this section. If a disposition amount arises from an RFA with respect
                to a section 743(b) CAA, in certain cases the disposition amount is
                allocated to a section 901(m) payor under paragraph (e) of this
                section. If there is a disposition of an RFA in a foreign taxable year
                of a foreign payor during which there is a mid-year transaction, in
                certain cases a disposition amount is allocated under paragraph (f) of
                this section. In certain cases in which the RFA owner (U.S.) either is
                a reverse hybrid or a fiscally transparent entity for both U.S. and
                foreign income tax purposes that is directly or indirectly owned by a
                reverse hybrid, a disposition amount is allocated to one or more
                section 901(m) payors under paragraph (g) of this section.
                 (2) Determining a disposition amount--(i) Disposition is fully
                taxable for purposes of both U.S. income tax and the foreign income
                tax. If a disposition of an RFA is fully taxable (that is, results in
                all gain or loss, if any, being recognized with respect to the RFA) for
                purposes of both U.S. income tax and the foreign income tax, the
                disposition amount is equal to the unallocated basis difference with
                respect to the RFA.
                 (ii) Disposition is not fully taxable for purposes of U.S. income
                tax or the foreign income tax (or both). If the disposition of an RFA
                is not fully taxable for purposes of both U.S. income tax and the
                foreign income tax, the disposition amount is determined under
                [[Page 16259]]
                this paragraph (c)(2)(ii). See Sec. 1.901(m)-6 for rules regarding the
                continued application of section 901(m) if the RFA has any unallocated
                basis difference after determining the disposition amount under
                paragraph (c)(2)(ii)(A) or (B) of this section, as applicable.
                 (A) Positive basis difference. If the disposition of an RFA is not
                fully taxable for purposes of both U.S. income tax and the foreign
                income tax, and the RFA has a positive basis difference, the
                disposition amount equals the lesser of:
                 (1) Any foreign disposition gain plus any U.S. disposition loss
                (for this purpose, expressed as a positive amount), or
                 (2) Unallocated basis difference with respect to the RFA.
                 (B) Negative basis difference. If the disposition of an RFA is not
                fully taxable for purposes of both U.S. income tax and the foreign
                income tax, and the RFA has a negative basis difference, the
                disposition amount equals the greater of:
                 (1) Any U.S. disposition gain (for this purpose, expressed as a
                negative amount) plus any foreign disposition loss, or
                 (2) Unallocated basis difference with respect to the RFA.
                 (iii) Disposition of an RFA after a section 743(b) CAA. If an RFA
                was subject to a section 743(b) CAA and subsequently there is a
                disposition of the RFA, then, for purposes of determining the
                disposition amount, foreign disposition gain or foreign disposition
                loss are specially defined to mean the amount of gain or loss
                recognized for purposes of the foreign income tax on the disposition of
                the RFA that is allocable to the partnership interest that was
                transferred in the section 743(b) CAA. In addition, U.S. disposition
                gain or U.S. disposition loss are specially defined to mean the amount
                of gain or loss recognized for U.S. income tax purposes on the
                disposition of the RFA that is allocable to the partnership interest
                that was transferred in the section 743(b) CAA, taking into account the
                basis adjustment under section 743(b) that was allocated to the RFA
                under section 755.
                 (d) General rules for allocating and assigning a cost recovery
                amount or a disposition amount when the RFA owner (U.S.) is a fiscally
                transparent entity--(1) In general. Except as provided in paragraphs
                (e), (f), and (g) of this section, this paragraph (d) provides rules
                for allocating a cost recovery amount or a disposition amount when the
                RFA owner (U.S.) is a fiscally transparent entity for U.S. income tax
                purposes in which a section 901(m) payor directly or indirectly owns an
                interest, as well as for assigning the allocated amount to a U.S.
                taxable year of the section 901(m) payor. For purposes of this
                paragraph (d), unless otherwise indicated, a reference to direct or
                indirect ownership in an entity means for U.S. income tax purposes. For
                purposes of this paragraph (d), a person indirectly owns an interest in
                an entity for U.S. income tax purposes if the person owns the interest
                through one or more fiscally transparent entities for U.S. income tax
                purposes, and at least one of the fiscally transparent entities is not
                a disregarded entity. For purposes of this paragraph (d), a person
                indirectly owns an interest in an entity for foreign income tax
                purposes if the person owns the interest through one or more fiscally
                transparent entities for foreign income tax purposes. If the RFA owner
                (U.S.) is a lower-tier fiscally transparent entity for U.S. income tax
                purposes in which the section 901(m) payor indirectly owns an interest,
                the rules of this section apply in a manner consistent with the
                application of these rules when the section 901(m) payor directly owns
                an interest in the RFA owner (U.S.).
                 (2) Allocation of a cost recovery amount. A cost recovery amount is
                allocated to a section 901(m) payor that directly or indirectly owns an
                interest in the RFA owner (U.S.) to the extent the U.S. basis deduction
                that corresponds to the cost recovery amount is (or will be) included
                in the section 901(m) payor's distributive share of the income of the
                RFA owner (U.S.) for U.S. income tax purposes.
                 (3) Allocation of a disposition amount attributable to foreign
                disposition gain or foreign disposition loss--(i) In general. Except as
                provided in paragraph (f) of this section, a disposition amount
                attributable to foreign disposition gain or foreign disposition loss
                (as determined under paragraph (d)(5) of this section) is allocated
                under paragraph (d)(3)(ii) or (d)(3)(iii) of this section to a section
                901(m) payor that directly or indirectly owns an interest in the RFA
                owner (U.S.).
                 (ii) First allocation rule. This paragraph (d)(3)(ii) applies when
                a section 901(m) payor, or a disregarded entity directly owned by a
                section 901(m) payor, is the foreign payor whose foreign income
                includes a distributive share of the foreign income of the RFA owner
                (foreign) and, therefore, all of the foreign income tax amount of the
                foreign payor is paid or accrued by, or considered paid by, the section
                901(m) payor. Thus, this paragraph (d)(3)(ii) applies when the RFA
                owner (U.S.) is a fiscally transparent entity for both U.S. and foreign
                income tax purposes and a section 901(m) payor either directly owns an
                interest in the RFA owner (U.S.) or directly owns an interest in
                another fiscally transparent entity for U.S. and foreign income tax
                purposes, which, in turn, directly or indirectly owns an interest in
                the RFA owner (U.S.) for both U.S. and foreign income tax purposes. In
                these cases, the section 901(m) payor is allocated the portion of a
                disposition amount that is equal to the product of the disposition
                amount attributable to foreign disposition gain or foreign disposition
                loss, as applicable, and a fraction, the numerator of which is the
                portion of the foreign disposition gain or foreign disposition loss
                recognized by the RFA owner (foreign) for foreign income tax purposes
                that is (or will be) included in the foreign payor's distributive share
                of the foreign income of the RFA owner (foreign), and the denominator
                of which is the foreign disposition gain or foreign disposition loss.
                 (iii) Second allocation rule. This paragraph (d)(3)(iii) applies
                when neither a section 901(m) payor nor a disregarded entity directly
                owned by a section 901(m) payor is the foreign payor with respect to
                the foreign income of the RFA owner (foreign). Instead, a section
                901(m) payor directly or indirectly owns an interest in the foreign
                payor, which is a fiscally transparent entity for U.S. income tax
                purposes (other than a disregarded entity directly owned by the section
                901(m) payor), and, therefore, the section 901(m) payor is considered
                to pay or accrue only its allocated portion of the foreign income tax
                amount of the foreign payor. This will be the case when the foreign
                payor is either the RFA owner (U.S.), another fiscally transparent
                entity for U.S. income tax purposes (other than a disregarded entity
                directly owned by a section 901(m) payor) that directly or indirectly
                owns an interest in the RFA owner (U.S.) for both U.S. and foreign
                income tax purposes, or a disregarded entity directly owned by the RFA
                owner (U.S.). In these cases, the section 901(m) payor is allocated the
                portion of a disposition amount that is equal to the product of the
                disposition amount attributable to foreign disposition gain or foreign
                disposition loss, as applicable, and a fraction, the numerator of which
                is the portion of the foreign disposition gain or foreign disposition
                loss that is included in the allocable foreign income of the section
                901(m) payor, and the denominator of which is the foreign disposition
                gain or foreign disposition loss. If allocable
                [[Page 16260]]
                foreign income is not otherwise required to be determined because there
                is no foreign income tax amount, the numerator is the portion of the
                foreign disposition gain or foreign disposition loss that would be
                included in the allocable foreign income of the section 901(m) payor if
                there were a foreign income tax amount.
                 (4) Allocation of a disposition amount attributable to U.S.
                disposition gain or U.S. disposition loss. A section 901(m) payor that
                directly or indirectly owns an interest in the RFA owner (U.S.) is
                allocated the portion of a disposition amount that is equal to the
                product of the disposition amount attributable to U.S. disposition gain
                or U.S. disposition loss (as determined under paragraph (d)(5) of this
                section), as applicable, and a fraction, the numerator of which is the
                portion of the U.S. disposition gain or U.S. disposition loss that is
                (or will be) included in the section 901(m) payor's distributive share
                of income of the RFA owner (U.S.) for U.S. income tax purposes, and the
                denominator of which is the U.S. disposition gain or U.S. disposition
                loss.
                 (5) Determining the extent to which a disposition amount is
                attributable to foreign or U.S. disposition gain or loss--(i) RFA with
                a positive basis difference. When there is a disposition of an RFA with
                a positive basis difference and the disposition results in either a
                foreign disposition gain or a U.S. disposition loss, but not both, the
                entire disposition amount is attributable to foreign disposition gain
                or U.S. disposition loss, as applicable, even if the disposition amount
                exceeds the foreign disposition gain or the absolute value of the U.S.
                disposition loss. If the disposition results in both a foreign
                disposition gain and a U.S. disposition loss, the disposition amount is
                attributable first to foreign disposition gain to the extent thereof,
                and the excess disposition amount, if any, is attributable to the U.S.
                disposition loss, even if the excess disposition amount exceeds the
                absolute value of the U.S. disposition loss.
                 (ii) RFA with a negative basis difference. When there is a
                disposition of an RFA with a negative basis difference and the
                disposition results in either a foreign disposition loss or a U.S.
                disposition gain, but not both, the entire disposition amount is
                attributable to foreign disposition loss or U.S. disposition gain, as
                applicable, even if the absolute value of the disposition amount
                exceeds the absolute value of the foreign disposition loss or the U.S.
                disposition gain. If the disposition results in both a foreign
                disposition loss and a U.S. disposition gain, the disposition amount is
                attributable first to foreign disposition loss to the extent thereof,
                and the excess disposition amount, if any, is attributable to the U.S.
                disposition gain, even if the absolute value of the excess disposition
                amount exceeds the U.S. disposition gain.
                 (6) U.S. taxable year of a section 901(m) payor to which an
                allocated cost recovery amount or disposition amount is assigned. A
                cost recovery amount or a disposition amount allocated to a section
                901(m) payor under paragraph (d) of this section is assigned to the
                U.S. taxable year of the section 901(m) payor that includes the last
                day of the U.S. taxable year of the RFA owner (U.S.) in which, in the
                case of a cost recovery amount, the RFA owner (U.S.) takes into account
                the corresponding U.S. basis deduction (without regard to whether the
                deduction is deferred or disallowed for U.S. income tax purposes), or
                in the case of a disposition amount, the disposition occurs.
                 (e) Special rules for certain section 743(b) CAAs. If a section
                901(m) payor acquires a partnership interest in a section 743(b) CAA,
                including a section 743(b) CAA with respect to a lower-tier partnership
                that results from a direct acquisition by the section 901(m) payor of
                an interest in an upper-tier partnership, and subsequently there is a
                cost recovery amount or a disposition amount that arises from an RFA
                with respect to that section 743(b) CAA, all of the cost recovery
                amount or the disposition amount is allocated to that section 901(m)
                payor. The U.S. taxable year of the section 901(m) payor to which the
                cost recovery amount or the disposition amount is assigned is the U.S.
                taxable year in which, in the case of a cost recovery amount, the
                section 901(m) payor takes into account the corresponding U.S. basis
                deduction (without regard to whether the deduction is deferred or
                disallowed for U.S. income tax purposes), or in the case of a
                disposition amount, the disposition occurs.
                 (f) Mid-year transactions--(1) In general. When a disposition of an
                RFA occurs in the same foreign taxable year that a foreign payor is
                involved in a mid-year transaction, the portion of the disposition
                amount that is attributable to foreign disposition gain or foreign
                disposition loss (as determined under paragraph (d)(5) of this section)
                is allocated to a section 901(m) payor and assigned to a U.S. taxable
                year of the section 901(m) payor under this paragraph (f). To the
                extent the disposition amount is attributable to U.S. disposition gain
                or U.S. disposition loss (as determined under paragraph (d)(5) of this
                section), see paragraph (c)(1) or (d) of this section, as applicable.
                 (2) Allocation rule. To the extent a disposition amount is
                attributable to foreign disposition gain or foreign disposition loss, a
                section 901(m) payor is allocated the portion of the disposition amount
                equal to the product of the disposition amount attributable to foreign
                disposition gain or foreign disposition loss, as applicable, and a
                fraction, the numerator of which is the portion of the foreign
                disposition gain or foreign disposition loss that is included in the
                allocable foreign income of the section 901(m) payor, and the
                denominator of which is the foreign disposition gain or foreign
                disposition loss. If allocable foreign income is not otherwise required
                to be determined because there is no foreign income tax amount, the
                numerator is the portion of the foreign disposition gain or foreign
                disposition loss that would be included in the allocable foreign income
                of the section 901(m) payor if there were a foreign income tax amount.
                 (3) Assignment to a U.S. taxable year of a section 901(m) payor. A
                disposition amount allocated to a section 901(m) payor under paragraph
                (f)(2) of this section is assigned to the U.S. taxable year of the
                section 901(m) payor in which the foreign disposition gain or foreign
                disposition loss (or portion thereof) is included in allocable foreign
                income of the section 901(m) payor or, if allocable foreign income is
                not otherwise required to be determined because there is no foreign
                income tax amount, the U.S. taxable year in which the foreign
                disposition gain or foreign disposition loss would be included in
                allocable foreign income if there were a foreign income tax amount.
                 (g) Reverse hybrids--(1) In general. This paragraph (g) provides
                rules for allocating a cost recovery amount or a disposition amount
                when the RFA owner (U.S.) is either a reverse hybrid or a fiscally
                transparent entity for U.S. and foreign income tax purposes that is
                directly or indirectly owned by a reverse hybrid for U.S. and foreign
                income tax purposes, and in each case, the foreign payor whose foreign
                income includes a distributive share of the foreign income of the RFA
                owner (foreign) directly or indirectly owns an interest in the reverse
                hybrid for foreign income tax purposes. Application of the allocation
                rules under paragraphs (g)(2) and (g)(3) of this section depend upon
                whether a section 901(m) payor or a disregarded entity directly owned
                by a section 901(m) payor is the foreign payor, or, instead, a section
                901(m) payor directly or indirectly owns an interest in the foreign
                payor. For purposes of this
                [[Page 16261]]
                paragraph (g), unless otherwise indicated, a reference to direct or
                indirect ownership in an entity means for U.S. income tax purposes. For
                purposes of this paragraph (g), a person indirectly owns an interest in
                an entity for U.S. income tax purposes if the person owns the interest
                through one or more fiscally transparent entities for U.S. income tax
                purposes, and at least one of the fiscally transparent entities is not
                a disregarded entity. For purposes of this paragraph (g), a person
                indirectly owns an interest in an entity for foreign income tax
                purposes if the person owns the interest through one or more fiscally
                transparent entities for foreign income tax purposes. If the RFA owner
                (U.S.) is a lower-tier fiscally transparent entity for U.S. income tax
                purposes in which the reverse hybrid indirectly owns an interest, the
                rules of this section apply in a manner consistent with the application
                of these rules when the reverse hybrid directly owns an interest in the
                RFA owner (U.S.).
                 (2) First allocation rule--(i) Allocation to a section 901(m)
                payor. This paragraph (g)(2)(i) applies when a section 901(m) payor, or
                a disregarded entity directly owned by a section 901(m) payor, is the
                foreign payor whose foreign income includes a distributive share of the
                foreign income of the RFA owner (foreign), and, therefore, all of the
                foreign income tax amount of the foreign payor is paid or accrued by,
                or considered paid or accrued by, the section 901(m) payor. Thus, this
                paragraph (g)(2)(i) applies when a section 901(m) payor either directly
                owns an interest in the reverse hybrid or directly owns an interest in
                a fiscally transparent entity for U.S. and foreign income tax purposes,
                which, in turn, directly or indirectly owns an interest in the reverse
                hybrid for both U.S. and foreign income tax purposes. In these cases,
                the section 901(m) payor is allocated the portions of cost recovery
                amounts or disposition amounts (or both) with respect to RFAs that are
                equal to the product of the sum of the cost recovery amounts and the
                disposition amounts and a fraction, the numerator of which is the
                portion of the foreign income of the RFA owner (foreign) that is
                included in the foreign income of the foreign payor, and the
                denominator of which is the foreign income of the RFA owner (foreign).
                 (ii) Assignment to a U.S. taxable year of a section 901(m) payor.
                This paragraph (g)(2)(ii) applies when a cost recovery amount or a
                disposition amount, or portion thereof, is allocated to a section
                901(m) payor under paragraph (g)(2)(i) of this section. If the reverse
                hybrid is the RFA owner (U.S.), a cost recovery amount or disposition
                amount, or portion thereof, is assigned to the U.S. taxable year of the
                section 901(m) payor that includes the last day of the U.S. taxable
                year of the reverse hybrid in which, in the case of a cost recovery
                amount, the reverse hybrid takes into account the corresponding U.S.
                basis deduction (without regard to whether the deduction is deferred or
                disallowed for U.S. income tax purposes), or, in the case of a
                disposition amount, the disposition occurs. If the reverse hybrid is
                not the RFA owner (U.S.) but instead the reverse hybrid directly or
                indirectly owns an interest in the RFA owner (U.S.) for both U.S. and
                foreign income tax purposes, a cost recovery amount or disposition
                amount, or portion thereof, is assigned to the U.S. taxable year of the
                section 901(m) payor that includes the last day of the U.S. taxable
                year of the reverse hybrid, which, in turn, includes the last day of
                the U.S. taxable year of the RFA owner (U.S.) in which, in the case of
                a cost recovery amount, the RFA owner (U.S.) takes into account the
                corresponding U.S. basis deduction (without regard to whether the
                deduction is deferred or disallowed for U.S. income tax purposes), or,
                in the case of a disposition amount, the disposition occurs.
                 (3) Second allocation rule--(i) Allocation to a section 901(m)
                payor. This paragraph (g)(3)(i) applies when neither a section 901(m)
                payor nor a disregarded entity directly owned by a section 901(m) payor
                is the foreign payor with respect to the foreign income of the RFA
                owner (foreign). Instead, a section 901(m) payor directly or indirectly
                owns an interest in the foreign payor, which is a fiscally transparent
                entity for U.S. income tax purposes (other than a disregarded entity
                directly owned by the section 901(m) payor), and, therefore, the
                section 901(m) payor is considered to pay or accrue only its allocated
                portion of the foreign income tax amount of the foreign payor. In these
                cases, the section 901(m) payor is allocated the portions of cost
                recovery amounts or disposition amounts (or both) with respect to RFAs
                that are equal to the product of the sum of the cost recovery amounts
                and the disposition amounts and a fraction, the numerator of which is
                the portion of the foreign income of the RFA owner (foreign) that is
                included in the foreign income of the foreign payor and included in the
                allocable foreign income of the section 901(m) payor, and the
                denominator of which is the foreign income of the RFA owner (foreign).
                If allocable foreign income is not otherwise required to be determined
                for a section 901(m) payor because there is no foreign income tax
                amount, the numerator is the foreign income of the RFA owner (foreign)
                that is included in the foreign income of the foreign payor and that
                would be included in allocable foreign income of the section 901(m)
                payor if there were a foreign income tax amount.
                 (ii) Assignment to a U.S. taxable year of a section 901(m) payor. A
                cost recovery amount or a disposition amount, or portion thereof, that
                is allocated to a section 901(m) payor under paragraph (g)(3)(i) of
                this section is assigned to the U.S. taxable year of the section 901(m)
                payor in which the foreign income of the RFA owner (foreign) described
                in paragraph (g)(3)(i) of this section is included in the allocable
                foreign income of the section 901(m) payor, or, if there is no foreign
                income tax amount, the U.S. taxable year of the section 901(m) payor in
                which the foreign income of the RFA owner (foreign) described in
                paragraph (g)(3)(i) of this section would be included in allocable
                foreign income if there were a foreign income tax amount.
                 (h) Examples. The following examples illustrate the rules of this
                section. In addition to any facts described in a particular example,
                the following facts apply to all the examples unless otherwise
                specified: CFC1, CFC2, and DE are organized in Country F and treated as
                corporations for Country F tax purposes. CFC1 and CFC2 are each an
                applicable foreign corporation that is wholly owned by the same U.S.
                corporation, and DE is a disregarded entity. CFC1 and CFC2 each have a
                U.S. taxable year that is a calendar year, and CFC1, CFC2, and DE each
                have a foreign taxable year that is a calendar year. Country F imposes
                a single tax that is a foreign income tax. CFC1, CFC2, and DE each have
                a functional currency of the u with respect to all activities. At all
                relevant times, 1u equals $1. All amounts are stated in millions. The
                examples assume that the applicable cost recovery method for property
                results in basis being recovered ratably over the life of the property
                beginning on the first day of the U.S. taxable year in which the
                property is acquired or placed into service.
                 (1) Example 1: CAA followed by disposition: Fully taxable for
                both U.S. income tax and foreign income tax purposes--(i) Facts. (A)
                On January 1, Year 1, USP acquires all of the stock of CFC1 in a
                qualified stock purchase (as defined in section 338(d)(3)) to which
                section 338(a) applies (Section 338 Acquisition). At the time of the
                Section 338 Acquisition, CFC1 owns a single asset (Asset A) that is
                located
                [[Page 16262]]
                in Country F. Asset A gives rise to income that is taken into
                account for Country F tax purposes. Asset A is tangible personal
                property that, under the applicable cost recovery method in the
                hands of CFC1, is depreciable over 5 years. There are no cost
                recovery deductions available for Country F tax purposes with
                respect to Asset A. Immediately before the Section 338 Acquisition,
                Asset A has a U.S. basis of 10u and a foreign basis of 40u.
                Immediately after the Section 338 Acquisition, Asset A has a U.S.
                basis of 100u and foreign basis of 40u.
                 (B) On July 1, Year 2, Asset A is transferred to an unrelated
                thirdparty in exchange for 120u in a transaction in which all
                realized gainis recognized for both U.S. income tax and Country F
                tax purposes(subsequent transaction). For U.S. income tax purposes,
                CFC1recognizes U.S. disposition gain of 50u (amount realized of
                120u, lessU.S. basis of 70u (100u cost basis, less 30u of
                accumulateddepreciation)) with respect to Asset A. The 30u of
                accumulateddepreciation is the sum of 20u of depreciation in Year 1
                (100u costbasis/5 years) and 10u of depreciation in Year 2 ((100u
                cost basis/5years) x 6/12). For Country F tax purposes, CFC1
                recognizes foreigndisposition gain of 80u (amount realized of 120u,
                less foreign basisof 40u) with respect to Asset A. Immediately after
                the subsequenttransaction, Asset A has a U.S. basis and a foreign
                basis of 120u.
                 (ii) Result. (A) Under Sec. 1.901(m)-2(b)(1), USP's acquisition
                of the stock of CFC1 in the Section 338 Acquisition is a section 338
                CAA. Under Sec. 1.901(m)-2(c)(i), Asset A is an RFA with respect to
                Country F tax because it is relevant in determining the foreign
                income of CFC1 for Country F tax purposes. Under Sec. 1.901(m)-
                4(b), the basis difference with respect to Asset A is 90u (100u-
                10u). Under Sec. 1.901(m)-1(a)(37), CFC1 is the RFA owner (U.S.)
                with respect to Asset A. Under Sec. 1.901(m)-1(a)(28), CFC1 is a
                foreign payor for Country F tax purposes. Under Sec. 1.901(m)-
                1(a)(41), CFC1 is the section 901(m) payor with respect to a foreign
                income tax amount for which CFC1 is the foreign payor (see Sec.
                1.901-2(f)(1)).
                 (B) Under Sec. 1.901(m)-1(a)(5), allocated basis differences
                are the sum of cost recovery amounts and disposition amounts. In
                Year 1, Asset A has an allocated basis difference that includes only
                a cost recovery amount. Under paragraph (b)(2) of this section, the
                cost recovery amount for Year 1 is determined by applying the
                applicable cost recovery method of Asset A in the hands of CFC1 to
                the basis difference with respect to Asset A. Accordingly, the cost
                recovery amount is 18u (90u basis difference/5 years). Under
                paragraph (b)(1) of this section, all of the 18u cost recovery
                amount is attributed to CFC1 and assigned to Year 1, because CFC1 is
                a section 901(m) payor and RFA owner (U.S.) with respect to Asset A
                and Year 1 is the U.S. taxable year of CFC1 in which it takes into
                account the corresponding 20u of depreciation. Immediately after
                Year 1, under Sec. 1.901(m)-1(a)(47), unallocated basis difference
                is 72u with respect to Asset A (90u-18u).
                 (C) In Year 2, Asset A has an allocated basis difference that
                includes both a cost recovery amount and a disposition amount. Under
                paragraph (b)(2) of this section, the cost recovery amount for Year
                2, as of the date of the subsequent transaction, is 9u ((90u basis
                difference/5 years) x 6/12). Under Sec. 1.901(m)-1(a)(15), the
                subsequent transaction is a disposition of Asset A, because the
                subsequent transaction is an event that results in an amount of gain
                being recognized for U.S. income tax and Country F tax purposes.
                Because all realized gain in Asset A is recognized for U.S. income
                tax and Country F tax purposes, the rule in paragraph (c)(2)(i) of
                this section applies to determine the disposition amount. Under that
                rule, the disposition amount for Year 2 is the unallocated basis
                difference of 63u (90u basis difference, less total 27u taken into
                account as cost recovery amounts in Year 1 and Year 2). Accordingly,
                the allocated basis difference for Year 2 is 72u (9u of cost
                recovery amount, plus 63u of disposition amount). Under paragraphs
                (b)(1) and (c)(1) of this section, all of the 72u of allocated basis
                difference is attributed to CFC1 and assigned to Year 2, because
                CFC1 is a section 901(m) payor and the RFA owner (U.S.) with respect
                to Asset A and Year 2 is the U.S. taxable year of CFC1 in which it
                takes into account the corresponding 10u of depreciation and in
                which the disposition occurred.
                 (D) Unallocated basis difference with respect to Asset A, as
                determined immediately after the subsequent transaction, is 0u (90u
                basis difference less 90u basis difference taken into account as 27u
                total cost recovery amount in Year 1 and Year 2 and as a 63u
                disposition amount in Year 2). Accordingly, because there is no
                unallocated basis difference with respect to Asset A attributable to
                the Section 338 Acquisition, the subsequent transaction is not a
                successor transaction as defined in Sec. 1.901(m)-6(b)(2).
                Furthermore, the subsequent transaction is not a CAA under Sec.
                1.901(m)-2(b). For these reasons, section 901(m) no longer applies
                to Asset A.
                 (2) Example 2: CAA followed by disposition: nontaxable for U.S.
                income tax purposes and taxable for foreign income tax purposes--(i)
                Facts. The facts are the same as in paragraph (h)(1)(i)(A) of this
                section (paragraph (i)(A) of Example 1) but the facts in paragraph
                (h)(1)(i)(B) of this section (paragraph (i)(B) of Example 1) are
                instead that on July 1, Year 2, Asset A is transferred to CFC2, in
                exchange for 100u of stock of CFC2 (subsequent transaction). For
                U.S. income tax purposes, CFC1 does not recognize any U.S.
                disposition gain or U.S. disposition loss with respect to Asset A.
                For Country F tax purposes, CFC1 recognizes foreign disposition gain
                of 60u (amount realized of 100u, less foreign basis of 40u) with
                respect to Asset A. Immediately after the subsequent transaction,
                Asset A has a U.S. basis of 70u (100u cost basis less 30u
                accumulated depreciation) and a foreign basis of 100u. The 30u of
                accumulated depreciation is the sum of 20u of depreciation in Year 1
                (100u cost basis/5 years) and 10u in Year 2 ((100u cost basis/5
                years) x 6/12).
                 (ii) Result. (A) The results described in paragraph
                (h)(1)(ii)(A) of this section (paragraph (ii)(A) of Example 1) also
                apply to this paragraph (h)(2)(ii) (the results of this Example 2).
                 (B) The result for Year 1 is the same as in paragraph
                (h)(1)(ii)(B) of this section (paragraph (ii)(B) of Example 1).
                 (C) In Year 2, Asset A has an allocated basis difference that
                includes both a cost recovery amount and a disposition amount. Under
                paragraph (b)(2) of this section, the cost recovery amount for Year
                2, as of the date of the subsequent transaction, is 9u ((90u basis
                difference/5 years) x 6/12). Under Sec. 1.901(m)-1(a)(15), the
                subsequent transaction is a disposition of Asset A, because the
                subsequent transaction is an event that results in an amount of gain
                being recognized for Country F tax purposes. Because the disposition
                is not also fully taxable for U.S. income tax purposes, the rule in
                paragraph (c)(2)(ii) of this section applies to determine the
                disposition amount. Under that rule, the disposition amount is 60u,
                the lesser of (i) 60u (60u foreign disposition gain plus absolute
                value of 0u U.S. disposition loss), and (ii) 63u unallocated basis
                difference (90 basis difference less total 27u taken into account as
                cost recovery amounts, 18u in Year 1 and 9u in Year 2). Accordingly,
                the allocated basis difference for the first half of Year 2 is 69u
                (9u of cost recovery amount, plus 60u of disposition amount). Under
                paragraphs (b)(1) and (c)(1) of this section, all of the 69u of
                allocated basis difference is attributed to CFC1 and assigned to
                Year 2, because CFC1 is a section 901(m) payor and the RFA owner
                (U.S.) with respect to Asset A and Year 2 is the U.S. taxable year
                of CFC1 in which it takes into account the corresponding 10u of
                depreciation and in which the disposition occurred.
                 (D) Unallocated basis difference with respect to Asset A
                immediately after the subsequent transaction is 3u (90u basis
                difference less 87u basis difference taken into account as a 27u
                total cost recovery amount in Year 1 and Year 2 and as a 60u
                disposition amount in Year 2). Accordingly, because there is
                unallocated basis difference of 3u with respect to Asset A
                attributable to the Section 338 Acquisition, as determined
                immediately after the subsequent transaction, the subsequent
                transaction is a successor transaction as defined in Sec. 1.901(m)-
                6(b)(2). Following the subsequent transaction, the unallocated basis
                difference of 3u must be taken into account as cost recovery amounts
                or disposition amounts (or both) by CFC2, the new section 901(m)
                payor and RFA owner (U.S.) of Asset A. See Sec. 1.901(m)-
                6(b)(3)(ii). Because the subsequent transaction is not a CAA under
                Sec. 1.901(m)-2(b), there is no additional basis difference with
                respect to Asset A as a result of the subsequent transaction.
                 (3) Example 3: CAA followed by disposition: nontaxable for both
                U.S. income tax and foreign income tax purposes--(i) Facts. The
                facts are the same as in paragraph (h)(1)(i)(A) of this section
                (paragraph (i)(A) of Example 1) but the facts in paragraph
                (h)(1)(i)(B) of this section (paragraph (i)(B) of Example 1) are
                instead that on July 1, Year 2, CFC1 transfers Asset A to CFC2, in
                exchange for 110u of stock of CFC2 (subsequent transaction). For
                U.S. income tax purposes, CFC1 does not recognize any U.S.
                [[Page 16263]]
                disposition gain or U.S. disposition loss with respect to Asset A as
                a result of the subsequent transaction. Furthermore, for Country F
                tax purposes, CFC1 recognizes no foreign disposition gain or foreign
                disposition loss with respect to Asset A as a result of the
                subsequent transaction. Immediately after the subsequent
                transaction, Asset A has a U.S. basis of 70u (100u cost basis less
                30u accumulated depreciation) and a foreign basis of 40u. The 30u of
                accumulated depreciation is the sum of 20u of depreciation in Year 1
                (100u cost basis/5 years) and 10u in Year 2 ((100u cost basis/5
                years) x 6/12).
                 (ii) Result. (A) The result for Year 1 is the same as in
                paragraph (h)(1)(ii)(A) of this section (paragraph (ii)(A) of
                Example 1).
                 (B) The result for Year 1 is the same as in paragraph
                (h)(1)(ii)(B) of this section (paragraph (ii)(B) of Example 1).
                 (C) In Year 2, Asset A has an allocated basis difference that
                includes only a cost recovery amount. Under paragraph (b)(2) of this
                section, the cost recovery amount for Year 2, as of the date of the
                subsequent transaction, is 9u ((90u basis difference/5 years) x 6/
                12). Under Sec. 1.901(m)-1(a)(15), the subsequent transaction does
                not constitute a disposition of Asset A, because the subsequent
                transaction is not an event that results in an amount of gain or
                loss being recognized for U.S. income tax or for Country F tax
                purposes. Therefore, no disposition amount is taken into account for
                Asset A in Year 2. Under paragraph (b)(1) of this section, all of
                the 9u of allocated basis difference is attributed to CFC1 and
                assigned to Year 2, because CFC1 is a section 901(m) payor and RFA
                owner (U.S.) with respect to Asset A and Year 2 is the U.S. taxable
                year of CFC1 in which it takes into account the corresponding 10u of
                depreciation.
                 (D) Unallocated basis difference with respect to Asset A
                immediately after the subsequent transaction is 63u (90u basis
                difference, less 27u total cost recovery amounts, 18u in Year 1 and
                9u in Year 2). Accordingly, because there is unallocated basis
                difference of 63u with respect to Asset A attributable to the CAA,
                as determined immediately after the subsequent transaction, the
                subsequent transaction is a successor transaction as defined in
                Sec. 1.901(m)-6(b)(2). Following the subsequent transaction, the
                unallocated basis difference of 63u must be taken into account as
                cost recovery amounts or disposition amounts (or both) by CFC2, the
                new section 901(m) payor and RFA owner (U.S.) of Asset A. See Sec.
                1.901(m)-6(b)(3)(ii). Because the subsequent transaction is not a
                CAA under Sec. 1.901(m)-2(b), there is no additional basis
                difference with respect to Asset A as a result of the subsequent
                transaction.
                 (i) Applicability dates. (1) Except as provided in paragraph (i)(2)
                of this section, this section applies to CAAs occurring on or after
                March 23, 2020.
                 (2) Paragraphs (b)(2)(i) and (c)(2) of this section apply to CAAs
                occurring on or after July 21, 2014, and to CAAs occurring before that
                date resulting from an entity classification election made under Sec.
                301.7701-3 of this chapter that is filed on or after July 29, 2014, and
                that is effective on or before July 21, 2014. Paragraphs (b)(2)(i) and
                (c)(2) of this section also apply to CAAs occurring on or after January
                1, 2011, and before July 21, 2014, other than CAAs occurring before
                July 21, 2014, resulting from an entity classification election made
                under Sec. 301.7701-3 that is filed on or after July 29, 2014, and
                that is effective on or before July 21, 2014, but only with respect to
                basis difference determined under Sec. 1.901(m)-4T(e) with respect to
                the CAA.
                 (3) Taxpayers may, however, choose to apply provisions in this
                section before the date such provisions are applicable pursuant to
                paragraphs (i)(1) and (2) of this section, provided that they (along
                with any persons that are related (within the meaning of section 267(b)
                or 707(b)) to the taxpayer)--
                 (i) Consistently apply this section, Sec. 1.704-
                1(b)(4)(viii)(c)(4)(v) through (vii), Sec. 1.901(m)-1, Sec. 1.901(m)-
                3, Sec. 1.901(m)-4 (excluding Sec. 1.901(m)-4(e)), Sec. 1.901(m)-6,
                Sec. 1.901(m)-7, and Sec. 1.901(m)-8 to all CAAs occurring on or
                after January 1, 2011, and consistently apply Sec. 1.901(m)-2
                (excluding Sec. 1.901(m)-2(d)) to all CAAs occurring on or after
                December 7, 2016, on any original or amended tax return for each
                taxable year for which the application of the provisions listed in this
                paragraph (i)(3)(i) affects the tax liability and for which the statute
                of limitations does not preclude assessment or the filing of a claim
                for refund, as applicable;
                 (ii) File all tax returns described in paragraph (i)(3)(i) of this
                section for any taxable year ending on or before March 23, 2020, no
                later than March 23, 2021; and
                 (ii) Make appropriate adjustments to take into account deficiencies
                that would have resulted from the consistent application under
                paragraph (i)(3)(i) of this section for taxable years that are not open
                for assessment.

                0
                Par. 12. Section 1.901(m)-5T is removed.
                0
                Par. 13. Section 1.901(m)-6 is added to read as follows:
                Sec. 1.901(m)-6 Successor rules.
                 (a) In general. This section provides successor rules applicable to
                section 901(m). Paragraph (b) of this section provides rules for the
                continued application of section 901(m) after an RFA that has
                unallocated basis difference has been transferred, including special
                rules applicable to successor transactions that are also CAAs or that
                involve partnerships. Paragraph (c) of this section provides rules for
                determining when an aggregate basis difference carryover of a section
                901(m) payor either becomes an aggregate basis difference carryover of
                the section 901(m) payor with respect to another foreign payor or is
                transferred to another section 901(m) payor, and paragraph (d) of this
                section provides applicability dates.
                 (b) Successor rules for unallocated basis difference--(1) In
                general. Except as provided in paragraph (b)(4) of this section,
                section 901(m) continues to apply after a successor transaction to any
                unallocated basis difference attached to a transferred RFA until the
                entire basis difference has been taken into account as a cost recovery
                amount or a disposition amount (or both) under Sec. 1.901(m)-5.
                 (2) Definition of a successor transaction. A successor transaction
                occurs with respect to an RFA if, after a CAA (prior CAA), there is a
                transfer of the RFA for U.S. income tax purposes and the RFA has
                unallocated basis difference with respect to the prior CAA, determined
                immediately after the transfer. A successor transaction may occur
                regardless of whether the transfer of the RFA is a disposition, a CAA,
                or a non-taxable transaction for purposes of U.S. income tax. If the
                RFA was subject to multiple prior CAAs, a separate determination must
                be made with respect to each prior CAA as to whether the transfer is a
                successor transaction.
                 (3) Special considerations. (i) If an asset is an RFA with respect
                to more than one foreign income tax, this paragraph (b) applies
                separately with respect to each foreign income tax.
                 (ii) Any subsequent cost recovery amount for an RFA transferred in
                a successor transaction is determined based on the post-transaction
                applicable cost recovery method, as described in Sec. 1.901(m)-
                5(b)(3), that applies to the U.S. basis (or portion thereof) that
                corresponds to the unallocated basis difference.
                 (4) Successor transaction is a CAA--(i) In general. An asset may be
                an RFA with respect to multiple CAAs if a successor transaction is also
                a CAA (subsequent CAA). Except as otherwise provided in this paragraph
                (b)(4), if there is a subsequent CAA, unallocated basis difference with
                respect to any prior CAAs will continue to be taken into account under
                section 901(m) after the subsequent CAA. Furthermore, the subsequent
                CAA may give rise to additional basis difference subject to section
                901(m).
                [[Page 16264]]
                 (ii) Foreign basis election. If a foreign basis election is made
                under Sec. 1.901(m)-4(c) with respect to a foreign income tax in a
                subsequent CAA, any unallocated basis difference with respect to one or
                more prior CAAs will not be taken into account under section 901(m).
                The only basis difference that will be taken into account after the
                subsequent CAA with respect to that foreign income tax is the basis
                difference with respect to the subsequent CAA.
                 (iii) Multiple section 743(b) CAAs. If an RFA is subject to two
                section 743(b) CAAs (prior section 743(b) CAA and subsequent section
                743(b) CAA) and the same partnership interest is acquired in both the
                CAAs, the RFA will be treated as having no unallocated basis difference
                with respect to the prior section 743(b) CAA if the basis difference
                for the section 743(b) CAA is determined independently from the prior
                section 743(b) CAA. In this regard, see generally Sec. 1.743-1(f). If
                the subsequent section 743(b) CAA results from the acquisition of only
                a portion of the partnership interest acquired in the prior section
                743(b) CAA, then the transferor will be required to equitably apportion
                the unallocated basis difference attributable to the prior section
                743(b) CAA between the portion retained by the transferor and the
                portion transferred. In this case, with respect to the portion
                transferred, the RFAs will be treated as having no unallocated basis
                difference with respect to the prior section 743(b) CAA if basis
                difference for the subsequent section 743(b) CAA is determined
                independently from the prior section 743(b) CAA.
                 (5) Example. The following example illustrates the rules of
                paragraph (b) of this section.
                 (i) Facts. USP, a domestic corporation, wholly owns CFC, a
                foreign corporation organized in Country A and treated as a
                corporation for both U.S. and Country A tax purposes. FT is an
                unrelated foreign corporation organized in Country A and treated as
                a corporation for both U.S. and Country A tax purposes. FT owns one
                asset, a parcel of land (Asset). Country A imposes a single tax that
                is a foreign income tax. On January 1, Year 1, CFC acquires all of
                the stock of FT in exchange for 300u in a qualified stock purchase
                (as defined in section 338(d)(3)) to which section 338(a) applies
                (Acquisition). Immediately before the Acquisition, Asset had a U.S.
                basis of 100u, and immediately after the Acquisition, Asset had a
                U.S. basis of 300u. Effective on February 1, Year 1, FT elects to be
                a disregarded entity pursuant to Sec. 301.7701-3. As a result of
                the election, FT is deemed, for U.S. income tax purposes, to
                distribute Asset to CFC in liquidation (Deemed Liquidation)
                immediately before the closing of the day before the election is
                effective pursuant to Sec. 301.7701-3(g)(1)(iii) and (3)(ii). The
                Deemed Liquidation is disregarded for Country A tax purposes. No
                gain or loss is recognized on the Deemed Liquidation for either U.S.
                or Country A tax purposes.
                 (ii) Result. Under Sec. 1.901(m)-2(b)(1), the acquisition by
                CFC of the stock of FT is a section 338 CAA. Under Sec. 1.901(m)-
                2(c)(1), Asset is an RFA with respect to Country A tax and the
                Acquisition, because immediately after the Acquisition, Asset is
                relevant in determining foreign income of FT for Country A tax
                purposes, and FT owned Asset when the Acquisition occurred. Under
                Sec. 1.901(m)-4(b), the basis difference with respect to Asset is
                200u (300u--100u). Under Sec. 1.901(m)-2(b)(2), the Deemed
                Liquidation is a CAA (subsequent CAA) because the Deemed Liquidation
                is treated as an acquisition of assets for U.S. income tax purposes
                and is disregarded for Country A tax purposes. Because the U.S.
                basis in Asset is 300u immediately before and after the Deemed
                Liquidation, the subsequent CAA does not give rise to any additional
                basis difference. The Deemed Liquidation is not a disposition under
                Sec. 1.901(m)-1(a)(15) because it did not result in gain or loss
                being recognized with respect to Asset for U.S. or Country A tax
                purposes. Accordingly, no basis difference with respect to Asset is
                taken into account under Sec. 1.901(m)-5 as a result of the Deemed
                Liquidation, and the unallocated basis difference with respect to
                Asset immediately after the Deemed Liquidation is 200u (200u--0u).
                Under paragraph (b)(2) of this section, the Deemed Liquidation is a
                successor transaction because there is a transfer of Asset for U.S.
                income tax purposes from FT to CFC and Asset has unallocated basis
                difference with respect to the Acquisition immediately after the
                Deemed Liquidation. Accordingly, under paragraph (b)(1) of this
                section, section 901(m) will continue to apply to the unallocated
                basis difference with respect to Asset until the entire 200u basis
                difference has been taken into account under Sec. 1.901(m)-5.
                 (c) Successor rules for aggregate basis difference carryover--(1)
                Transfers of a section 901(m) payor's aggregate basis difference
                carryover to another person. If a corporation acquires the assets of a
                section 901(m) payor in a transaction to which section 381 applies,
                that corporation succeeds to any aggregate basis difference carryovers
                of the section 901(m) payor.
                 (2) Transfers of a section 901(m) payor's aggregate basis
                difference carryover with respect to a foreign payor to another foreign
                payor. If a section 901(m) payor has an aggregate basis difference
                carryover, with respect to a foreign income tax and a foreign payor,
                and substantially all of the assets of the foreign payor are
                transferred to another foreign payor in which the section 901(m) payor
                owns an interest, the section 901(m) payor's aggregate basis difference
                carryover with respect to the first foreign payor is transferred to the
                section 901(m) payor's aggregate basis difference carryover with
                respect to the other foreign payor. In such a case, the section 901(m)
                payor's aggregate basis difference carryover with respect to the first
                foreign payor is reduced to zero.
                 (3) Anti-abuse rule. If a section 901(m) payor has an aggregate
                basis difference carryover with respect to a foreign income tax and a
                foreign payor and, with a principal purpose of avoiding the application
                of section 901(m), assets of the foreign payor are transferred to
                another foreign payor in a transaction not described in paragraph
                (c)(1) or (2) of this section, then a portion of the aggregate basis
                difference carryover of the section 901(m) payor is transferred either
                to the aggregate basis difference carryover of the section 901(m) payor
                with respect to the other foreign payor or to another section 901(m)
                payor, as appropriate. The portion of the aggregate basis difference
                carryover transferred is determined based on the ratio of fair market
                value of the assets transferred to the fair market value of all of the
                assets of the foreign payor that transferred the assets. Similar
                principles apply when, with a principal purpose of avoiding the
                application of section 901(m), there is a change in the allocation of
                foreign income for foreign income tax purposes or the allocation of
                foreign income tax amounts for U.S. income tax purposes that would
                otherwise separate foreign income tax amounts from the related
                aggregate basis difference carryover.
                 (4) Ownership. For purposes of this paragraph (c), a section 901(m)
                payor owns an interest in a foreign payor if the section 901(m) payor
                owns the interest directly or indirectly through one or more fiscally
                transparent entities for U.S. income tax purposes.
                 (d) Applicability dates--(1) Except as provided in paragraph (d)(2)
                of this section, this section applies to CAAs occurring on or after
                March 23, 2020.
                 (2) Paragraphs (a), (b)(1) and (2), (b)(4)(i) and (iii), and (b)(5)
                of this section apply to CAAs occurring on or after July 21, 2014, and
                to CAAs occurring before that date resulting from an entity
                classification election made under Sec. 301.7701-3 of this chapter
                that is filed on or after July 29, 2014, and that is effective on or
                before July 21, 2014. Paragraphs (a), (b)(1) and (2), (b)(4)(i) and
                (iii), and (b)(5) of this section also apply to CAAs occurring on or
                after January 1, 2011, and before July 21, 2014, other than CAAs
                occurring before July 21, 2014, resulting from an entity classification
                election made under Sec. 301.7701-3 that is filed on or after July 29,
                2014, and that is effective on or before July 21, 2014, but only with
                [[Page 16265]]
                respect to basis difference determined under Sec. 1.901(m)-4T(e) with
                respect to the CAA.
                 (3) Taxpayers may, however, choose to apply provisions in this
                section before the date such provisions are applicable pursuant to
                paragraphs (d)(1) and (2) of this section, provided that they (along
                with any persons that are related (within the meaning of section 267(b)
                or 707(b)) to the taxpayer)--
                 (i) Consistently apply this section, Sec. 1.704-
                1(b)(4)(viii)(c)(4)(v) through (vii), Sec. 1.901(m)-1, Sec. Sec.
                1.901(m)-3 through 1.901(m)-5 (excluding Sec. 1.901(m)-4(e)), Sec.
                1.901(m)-7, and Sec. 1.901(m)-8 to all CAAs occurring on or after
                January 1, 2011, and consistently apply Sec. 1.901(m)-2 (excluding
                Sec. 1.901(m)-2(d)) to all CAAs occurring on or after December 7,
                2016, on any original or amended tax return for each taxable year for
                which the application of the provisions listed in this paragraph
                (d)(3)(i) affects the tax liability and for which the statute of
                limitations does not preclude assessment or the filing of a claim for
                refund, as applicable;
                 (ii) File all tax returns described in paragraph (d)(3)(i) of this
                section for any taxable year ending on or before March 23, 2020, no
                later than March 23, 2021; and
                 (iii) Make appropriate adjustments to take into account
                deficiencies that would have resulted from the consistent application
                under paragraph (d)(3)(i) of this section for taxable years that are
                not open for assessment.

                0
                Par. 15. Section 1.901(m)-7 is added to read as follows:
                Sec. 1.901(m)-7 De minimis rules.
                 (a) In general. This section provides rules describing basis
                difference that is not taken into account under section 901(m) because
                a CAA results in a de minimis amount of basis difference. Paragraph (b)
                of this section sets forth the general rule for determining whether the
                de minimis threshold is met. Paragraph (c) of this section modifies the
                general rule in the case of CAAs that are part of an aggregated CAA
                transaction. Paragraph (d) of this section provides rules for applying
                this section, and paragraph (e) of this section provides an anti-abuse
                rule applicable to related persons. Paragraph (f) of this section
                provides examples that illustrate the application of this section.
                Paragraph (g) of this section provides applicability dates.
                 (b) General rule--(1) In general. A basis difference with respect
                to an RFA and a foreign income tax is not taken into account under
                section 901(m) if the requirements under the cumulative basis
                difference exemption, the RFA class exemption, or the RFA exemption are
                satisfied.
                 (2) Cumulative basis difference exemption. Except as provided in
                paragraph (c) of this section, a basis difference, with respect to an
                RFA and a foreign income tax, is not taken into account under section
                901(m) (cumulative basis difference exemption) if the sum of that basis
                difference and all other basis differences (including negative basis
                differences), with respect to a single CAA and a single RFA owner
                (U.S.), is less than the greater of:
                 (i) $10 million, or
                 (ii) 10 percent of the total U.S. basis of all the RFAs immediately
                after the CAA.
                 (3) RFA class exemption--(i) Except as provided in paragraph (c) of
                this section, a basis difference, with respect to an RFA and a foreign
                income tax, is not taken into account under section 901(m) (RFA class
                exemption) if the RFA is part of a class of RFAs and the absolute value
                of the sum of the basis differences (including negative basis
                differences), with respect to a single CAA and a single RFA owner, for
                all the RFAs in that class is less than the greater of:
                 (A) $2 million, or
                 (B) 10 percent of the total U.S. basis of all the RFAs in that
                class of RFAs immediately after the CAA.
                 (ii) For purposes of this paragraph (b)(3), the classes of RFAs are
                the seven asset classes defined in Sec. 1.338-6(b), regardless of
                whether the CAA is a section 338 CAA.
                 (4) RFA exemption. A basis difference, with respect to an RFA and a
                foreign income tax, is not taken into account under section 901(m) (RFA
                exemption) if the absolute value of the basis difference with respect
                to the RFA is less than $20,000.
                 (c) Special rule if a CAA is part of an aggregated CAA transaction.
                If a CAA is part of an aggregated CAA transaction and a single RFA
                owner (U.S.) does not own all the RFAs attributable to the CAAs that
                are part of the aggregated CAA transaction, the cumulative basis
                difference exemption and the RFA class exemption apply to such CAA only
                if, in addition to satisfying the requirements of paragraph (b)(2) or
                (b)(3) of this section, respectively, determined without regard to this
                paragraph (c), the cumulative basis difference exemption or the RFA
                class exemption, as modified by this paragraph (c), is satisfied.
                Solely for purposes of this paragraph (c), the cumulative basis
                difference exemption and the RFA class exemption are applied taking
                into account all the basis differences with respect to all the RFAs
                owned by all the RFA owners (U.S.) that are attributable to the CAAs
                that are part of the aggregated CAA transaction.
                 (d) Rules of application. The following rules apply for purposes of
                this section.
                 (1) Whether a basis difference qualifies for the cumulative basis
                difference exemption, the RFA class exemption, or the RFA exemption is
                determined when an asset first becomes an RFA with respect to a CAA. In
                the case of a subsequent CAA described in Sec. 1.901(m)-6(b)(4), the
                application of the cumulative basis difference exemption, the RFA class
                exemption, and the RFA exemption is based on basis difference, if any,
                that results from the subsequent CAA.
                 (2) If there is an aggregated CAA transaction, the cumulative basis
                difference exemption and each RFA class exemption are applied by
                treating all CAAs that are part of the aggregated CAA transaction as a
                single CAA.
                 (3) Basis difference is computed in accordance with Sec. 1.901(m)-
                4 except that a foreign basis election need not be evidenced if the
                cumulative basis difference exemption, an RFA class exemption, or the
                RFA exemption apply to all RFAs with respect to the CAA.
                 (4) Basis difference is translated into U.S. dollars (if necessary)
                using the spot rate determined under the principles of Sec. 1.988-1(d)
                on the date of the CAA.
                 (e) Anti-abuse rule. The cumulative basis difference exemption, an
                RFA class exemption, and the RFA exemption are not available if the
                transferor and transferee in the CAA are related persons (as described
                in section 267(b) or 707(b)) and the CAA was entered into, or
                structured, with a principal purpose of avoiding the application of
                section 901(m). See also Sec. 1.901(m)-8(c), which provides that
                certain built-in loss assets are not taken into account for purposes of
                applying this section.
                 (f) Examples. The following examples illustrate the rules of this
                section:
                 (1) Example 1: De minimis; cumulative basis difference
                exemption--(i) Facts. USP, a domestic corporation, as part of a
                plan, purchases all of the stock of CFC1 and CFC2 from a single
                seller. CFC1 and CFC2 are applicable foreign corporations, organized
                in Country F, and treated as corporations for Country F tax
                purposes. Country F imposes a single tax that is a foreign income
                tax. Each acquisition is a qualified stock purchase (as defined in
                section 338(d)(3)) to which section
                [[Page 16266]]
                338(a) applies. A foreign basis election is not made under Sec.
                1.901(m)-4(c). Immediately after the acquisition of the stock of
                CFC1 and CFC2, the assets of CFC1 and CFC2 give rise to income that
                is taken into account for Country F tax purposes, and those assets
                are in a single class, as defined in Sec. 1.338-6(b). Assume that
                the absolute value of the basis difference with respect to any
                single RFA is greater than $20,000. At all relevant times, 1u equals
                $1. All amounts are stated in millions. The additional facts are
                summarized below.

                ----------------------------------------------------------------------------------------------------------------
                 (ii) Result. (A) Under Sec. 1.901(m)-2(b)(1), USP's
                acquisitions of the stock of CFC1 and CFC2 are each a section 338
                CAA. Under 1.901(m)-1(a)(3), the two section 338 CAAs constitute an
                aggregated CAA transaction because the acquisitions occur as part of
                a plan. Under Sec. 1.901(m)-2(c)(1), the assets of CFC1 and CFC2
                are RFAs for Country F tax purposes because they are relevant in
                determining foreign income of CFC1 and CFC 2, respectively, for
                Country F tax purposes. Under Sec. 1.901(m)-1(a)(37), CFC1 is the
                RFA owner (U.S.) with respect to its assets, and CFC2 is the RFA
                owner (U.S.) with respect to its assets.
                 (B) Under paragraph (b)(2) of this section, the application of
                the cumulative basis difference exemption is based on a single CAA
                and a single RFA owner (U.S.), subject to the requirements under
                paragraph (c) of this section that apply when there is an aggregated
                CAA transaction. In the case of the section 338 CAA with respect to
                CFC1, without regard to paragraph (c) of this section, the
                requirements of the cumulative basis difference exemption are
                satisfied if the sum of the basis differences is less than the
                threshold of $10 million, the greater of $10 million or $6 million
                (10% of the total U.S. basis of $60 million (60 million u translated
                into dollars at the exchange rate of $1 = 1u)). In this case, the
                sum of the basis differences is $12 million (12 million u translated
                into dollars at the exchange rate of $1 = 1 u). Because the sum of
                the basis differences of $12 million is not less than the threshold
                of $10 million, the requirements of the cumulative basis difference
                exemption are not satisfied. Because the requirements of the
                cumulative basis difference exemption are not satisfied, without
                regard to paragraph (c) of this section, paragraph (c) of this
                section is not applicable. The RFA class exemption is not relevant
                because all of the RFAs of CFC1 are in a single class. Finally,
                because the absolute value with respect to each RFA is greater than
                $20,000, the RFA exemption does not apply. Accordingly, the basis
                differences with respect to all of the RFAs of CFC1 must be taken
                into account under section 901(m).
                 (C) In the case of the section 338 CAA with respect to CFC2,
                without regard to paragraph (c) of this section, the requirements of
                the cumulative basis difference exemption are satisfied if the sum
                of the basis differences is less than the threshold of $10 million,
                the greater of $10 million or $ 9.6 million (10% of the total U.S.
                basis of $96 million (96 million u translated into dollars at the
                exchange rate of $1 = 1u)) In this case, the sum of the basis
                differences is ($4) million ((4) million u translated into dollars
                at the exchange rate of $1 = 1 u). Because the sum of the basis
                differences of ($4) million is less than the threshold of $10
                million, the requirements of the cumulative basis difference
                exemption are satisfied. However, because the section 338 CAA with
                respect to CFC2 is part of an aggregated CAA transaction that
                includes the section 338 CAA with respect to CFC1, paragraph (c) of
                this section is applicable. Under paragraph (c) of this section, the
                requirements of the cumulative basis difference exemption must also
                be satisfied taking into account all of the RFAs of both CFC2 and
                CFC1. In this case, the requirements of the cumulative basis
                difference exemption for purposes of paragraph (c) of this section
                are satisfied if the sum of the basis differences with respect to
                all of the RFAs of CFC2 and CFC1 is less than the threshold of $15.6
                million, the greater of $10 million or $15.6 million (10% of the
                total U.S. basis of $156 million (156 million u translated into
                dollars at the exchange rate of $1 = 1u)). In this case, the sum of
                the basis differences is $8 million (8 million u translated into
                dollars at the exchange rate of $1 = 1 u). Because the sum of the
                basis differences of $8 million is less than the threshold of $15.6
                million, the requirements of the cumulative basis difference
                exemption are satisfied in the case of the section 338 CAA with
                respect to CFC2. Accordingly, none of the basis differences with
                respect to the RFAs of CFC2 are taken into account under section
                901(m).
                 (2) Example 2: De minimis; RFA Class Exemption--(i) Facts. USP,
                a domestic corporation, acquires all the stock of CFC, an applicable
                foreign corporation organized in Country F and treated as a
                corporation for Country F tax purposes, in a qualified stock
                purchase (as defined in section 338(d)(3)) to which section 338(a)
                applies. Country F imposes a single tax that is a foreign income
                tax. A foreign basis election is not made under Sec. 1.901(m)-4(c).
                Immediately after the acquisition of CFC, the assets of CFC give
                rise to income that is taken into account for Country F tax
                purposes. Assume that the absolute value of the basis difference
                with respect to any single RFA is greater than $20,000. At all
                relevant times, 1u equals $1. All amounts are stated in millions.
                The additional facts are summarized below.

                ----------------------------------------------------------------------------------------------------------------
                 (ii) Result. (A) Under Sec. 1.901(m)-2(b)(1), USP's acquisition
                of the stock of CFC is a section 338 CAA. Under Sec. 1.901(m)-
                2(c)(1), the assets of CFC are RFAs for Country F tax purposes
                because they are relevant in determining foreign income of CFC for
                Country F tax purposes.
                 (B) Under paragraph (b)(2) of this section, the requirements of
                the cumulative basis difference exemption are satisfied if the sum
                of the basis differences is less than the threshold of $10 million,
                the greater of $10 million or $5.5 million (10% of the total U.S.
                basis of $55 million (55 million u translated into dollars at the
                exchange rate of $1 = 1u)). In this case, the sum of the basis
                differences is $12 million (12 million u translated into dollars at
                the exchange rate of $1 = 1 u). Because the sum of the basis
                differences of $12 million is not less than the threshold of $10
                million, the requirements of the cumulative basis difference
                exemption are not satisfied.
                 (C) Under paragraph (b)(3) of this section, each of CFC's assets
                is allocated to its class under Sec. 1.338-6(b) for purposes of the
                RFA class exemption. The requirements of the
                [[Page 16267]]
                RFA class exemption with respect to the Class IV RFAs (in this case,
                inventory) are satisfied if the absolute value of the sum of the
                basis differences with respect to the Class IV RFAs is less than the
                threshold of $2 million, the greater of $2 million or $1.5 million
                (10% of the total U.S. basis of Class IV RFAs of $15 million (15
                million u translated into dollars at the exchange rate of $1 = 1u)).
                In this case, the absolute value of the sum of the basis differences
                is $1 million (1 million u translated into dollars at the exchange
                rate of $1 = 1 u). Because the sum of the basis differences of $1
                million is less than the threshold of $2 million, the requirements
                of the RFA class exemption are satisfied. Accordingly, the basis
                differences with respect to the Class IV RFAs are not taken into
                account under section 901(m).
                 (D) The requirements of the RFA class exemption with respect to
                the Class V RFAs (in this case, buildings) is satisfied if the
                absolute value of the sum of the basis differences with respect to
                the Class V RFAs is less than the threshold of $3 million, the
                greater of $2 million or $3 million (10% of the total U.S. basis of
                Class V RFAs of $30 million (30 million u translated into dollars at
                the exchange rate of $1 = 1u)). In this case, the absolute value of
                the sum of the basis differences is $11 million (11 million u
                translated into dollars at the exchange rate of $1 = 1 u). Because
                the sum of the basis differences of $11 million is not less than the
                threshold of $3 million, the requirements of the RFA class exemption
                are not satisfied. Finally, because the absolute value with respect
                to each RFA is greater than $20,000, the RFA exemption does not
                apply. Accordingly, the basis differences with respect to the Class
                V RFAs are taken into account under section 901(m).
                 (E) The Class I RFAs (in this case, cash) are irrelevant because
                there are no basis differences with respect to those RFAs.
                 (g) Applicability dates. This section applies to CAAs occurring on
                or after March 23, 2020. Taxpayers may, however, choose to apply this
                section before the date this section is applicable provided that they
                (along with any persons that are related (within the meaning of section
                267(b) or 707(b)) to the taxpayer)--
                 (1) Consistently apply this section, Sec. 1.704-
                1(b)(4)(viii)(c)(4)(v) through (vii), Sec. 1.901(m)-1, Sec. Sec.
                1.901(m)-3 through 1.901(m)-6 (excluding Sec. 1.901(m)-4(e)), and
                Sec. 1.901(m)-8 to all CAAs occurring on or after January 1, 2011, and
                consistently apply Sec. 1.901(m)-2 (excluding Sec. 1.901(m)-2(d)) to
                all CAAs occurring on or after December 7, 2016, on any original or
                amended tax return for each taxable year for which the application of
                the provisions listed in this paragraph (g)(1) affects the tax
                liability and for which the statute of limitations does not preclude
                assessment or the filing of a claim for refund, as applicable;
                 (2) File all tax returns described in paragraph (g)(1) of this
                section for any taxable year ending on or before March 23, 2020, no
                later than March 23, 2021; and
                 (3) Make appropriate adjustments to take into account deficiencies
                that would have resulted from the consistent application under
                paragraph (g)(1) of this section for taxable years that are not open
                for assessment.

                Par. 17. Section 1.901(m)-8 is added to read as follows:
                Sec. 1.901(m)-8 Miscellaneous.
                 (a) In general. This section provides guidance on other matters
                under section 901(m). Paragraph (b) of this section provides guidance
                on the application of section 901(m) to pre-1987 foreign income taxes.
                Paragraph (c) of this section provides anti-abuse rules relating to
                built-in loss assets. Paragraph (d) of this section provides guidance
                on the interaction of section 901(m) and section 909. Paragraph (e) of
                this section provides applicability dates.
                 (b) Application of section 901(m) to pre-1987 foreign income taxes.
                Section 901(m) and Sec. Sec. 1.901(m)-1 through 1.901-8 apply to pre-
                1987 foreign income taxes (as defined in Sec. 1.902-1(a)(10)(iii)) of
                an applicable foreign corporation.
                 (c) Anti-abuse rule for built-in loss RFAs. A basis difference with
                respect to an RFA described in section 901(m)(3)(C)(ii) (built-in loss
                RFA) will not be taken into account for purposes of computing an
                allocated basis difference for a U.S. taxable year of a section 901(m)
                payor if any RFA, including an RFA other than built-in loss RFAs, is
                acquired with a principal purpose of using one or more built-in loss
                RFAs to avoid the application of section 901(m). Furthermore, a basis
                difference with respect to a built-in loss RFA will not be taken into
                account for purposes of the cumulative basis difference exemption or
                the RFA class exemption under Sec. 1.901(m)-7 if any RFAs, including
                RFAs other than built-in loss RFAs, are acquired with a principal
                purpose of avoiding the application of section 901(m).
                 (d) Interaction with section 909. The amount of a foreign income
                tax that is disqualified under section 901(m) is determined before
                applying section 909. However, section 909 may apply to suspend a
                deduction for the amount of a foreign income tax that is disqualified
                under section 901(m).
                 (e) Applicability dates. This section applies to CAAs occurring on
                or after March 23, 2020. Taxpayers may, however, choose to apply this
                section before the date this section is applicable provided that they
                (along with any persons that are related (within the meaning of section
                267(b) or 707(b)) to the taxpayer)--
                 (1) Consistently apply this section, Sec. 1.704-
                1(b)(4)(viii)(c)(4)(v) through (vii), Sec. 1.901(m)-1, and Sec. Sec.
                1.901(m)-3 through 1.901(m)-7 (excluding Sec. 1.901(m)-4(e)) to all
                CAAs occurring on or after January 1, 2011, and consistently apply
                Sec. 1.901(m)-2 (excluding Sec. 1.901(m)-2(d)) to all CAAs occurring
                on or after December 7, 2016, on any original or amended tax return for
                each taxable year for which the application of the provisions listed in
                this paragraph (e)(1) affects the tax liability and for which the
                statute of limitations does not preclude assessment or the filing of a
                claim for refund, as applicable;
                 (2) File all tax returns described in paragraph (e)(1) of this
                section for any taxable year ending on or before March 23, 2020, no
                later than March 23, 2021; and
                 (3) Make appropriate adjustments to take into account deficiencies
                that would have resulted from the consistent application under
                paragraph (e)(2) of this section for taxable years that are not open
                for assessment.
