Treasury and the IRS have taken a significant step toward easing the compliance burden associated with the Section 987 foreign currency rules for multinational groups. Proposed regulations (PDF - 415.17KB) issued on Aug. 14 would allow controlled foreign corporations (CFCs) to elect out of computing and recognizing foreign currency gains and losses on certain transfers involving their foreign branches, an approach first previewed in February’s Notice 2026-17 (PDF - 217.22KB).
While the election is broadly taxpayer-favorable and generally reduces the ongoing administrative complexity created by the 2024 final Section 987 regulations, it does not provide a complete exemption. Electing CFCs must still comply with key Section 987 income and earnings-and-profits calculations, and certain pre-election gains, losses and transaction-related adjustments remain subject to recognition rules.
The proposed regulations also implement a 120-month amortization rule for pre-election Section 987 gains and losses, announced in Notice 2025-72. The remaining items previewed in the February 2026 notice, including the equity-pool and basis-pool method and the narrowed loss suspension rules, are expected to be addressed in a separate notice of proposed rulemaking. (See our prior coverage of the 2024 final regulations here and our discussion of Notice 2026-17 here.)
Background
Section 987 applies to any taxpayer that owns a qualified business unit (QBU) with a functional currency other than the U.S. dollar. Sections 987(1) and (2) provide rules for determining and translating a QBU’s taxable income or loss, while Section 987(3) requires taxpayers to recognize foreign currency gains and losses that arise on transfers of property between QBUs using different functional currencies, including transfers between a CFC and its QBUs. Under Section 987(3), the owner of a QBU generally must recognize a Section 987 gain or loss upon a remittance from the QBU.
On Dec. 11, 2024, Treasury and the IRS published final regulations (PDF - 909.14KB) that retained the foreign exchange exposure pool framework and applied Section 987(3) to CFCs. In the preamble to the concurrent 2024 proposed regulations, Treasury and the IRS requested comments on whether Section 987(3) should apply to CFCs at all, recognizing that a CFC is permitted under Section 985 to compute its income in a non-dollar functional currency, such that its income is not necessarily measured by an accession to wealth in U.S. dollars.
At the same time, Treasury and the IRS expressed concern that turning off Section 987(3) for CFCs could allow asset basis attributable to currency appreciation to be imported into the U.S. in an inbound nonrecognition transaction without a corresponding income inclusion.
On Feb. 25, 2026, Treasury and the IRS issued Notice 2026-17, announcing a package of simplification measures, including the CFC exemption election. The notice described the election and its consistency requirements but did not provide the operative rules in detail or permit taxpayers to rely on the CFC election.
Key elements
The CFC exemption election
Under the proposed regulations, a taxpayer may elect to limit the application of Section 987(3) with respect to its CFCs. In a taxable year to which the election applies, an electing CFC (an “exempt CFC”) generally does not compute or recognize a Section 987 gain or loss, and the rules of Section 1.987-4 through 1.987-6 and Section 1.987-11 through 1.987-14 generally do not apply to it.
The determination of Section 987 taxable income or loss under Section 1.987-3 continues to apply, and the regulations deem a current rate election to be in effect for each exempt CFC, so that historic exchange rates do not need to be tracked. QBU income is translated at the yearly average exchange rate, and transfers between a QBU and its owner are translated at the spot rate.
Certain partnerships and their QBUs also can qualify for exempt treatment, generally where at least 80% of the capital or profits interests are owned, directly or indirectly, by exempt CFCs in the same controlled group.
The election is a Section 987 election within the meaning of Section 1.987-1(g) and is made by the authorized person for the relevant Section 987 electing group. The election generally must be made on a timely filed return, although special transition rules permit the election to be made on an amended return in certain cases for taxable years beginning before 2027. The election generally cannot be revoked without the consent of the IRS commissioner, which may be obtained through a private letter ruling.
Consistency requirements
The Section 987 election consistency rules apply to the CFC exemption election, subject to two modifications. Under the general rule, a Section 987 election must be made consistently for all members of a Section 987 electing group, which includes each CFC in which the relevant U.S. shareholder owns, within the meaning of Section 958(a), more than 50% of the stock by vote or value. A CFC that joins an electing group is deemed to make or revoke elections as necessary to conform.
The two modifications broaden the group that must conform. First, all domestic corporations that are affiliated generally must make consistent CFC exemption elections with respect to their majority-owned CFCs. This requires consistency between certain related but non-consolidated corporations, including separate consolidated groups that are commonly owned by a foreign parent, and corporations that would be members of the same consolidated group but for the interposition of a partnership.
Second, a U.S. person is treated as owning CFC stock that it holds indirectly through a domestic partnership, as the domestic partnership is treated in the same manner as a foreign partnership in applying Section 958(a).
The proposed regulations also include anti-avoidance rules that can treat the election as made, or disregard a purported revocation, where a related-party transaction is undertaken with a principal purpose of avoiding the consistency requirements or triggering a deemed revocation.
Pre-election Section 987 gain or loss
A taxpayer that makes the election generally must compute their pre-election Section 987 gain or loss and may not elect out of doing so. Treasury and the IRS declined to permit an election to eliminate these amounts, reasoning that a “fresh start” approach would expose the government to whipsaw, because taxpayers with a pre-election gain could eliminate it while taxpayers with a pre-election loss could preserve and amortize it. A pre-election Section 987 gain or loss is generally recognized ratably over 120 months beginning with the first month of the first taxable year in which the election applies.
A de minimis exception generally applies to QBUs with average assets of less than $50 million during the three taxable years preceding the first election year, based on the total assets reported on Schedule F of Form 8858, allowing these taxpayers to treat a pre-election Section 987 gain or loss as zero.
Inbound nonrecognition transactions
Special rules are intended to require recognition of a Section 987 gain when excess asset basis is imported into the U.S. in certain transactions. The rules generally apply when a domestic corporation acquires the assets of a transferor CFC in an inbound nonrecognition transaction — generally a Section 332 liquidation or a Section 368 reorganization — and the transferor CFC was subject to a CFC exemption election for any taxable year ending during the 72-month period preceding the transaction. Thus, the rule may apply even if the election is no longer in effect when the inbound transaction occurs.
A de minimis exception applies if the transferor CFC’s aggregate tax basis in its assets is less than $25 million, in which case the Section 987 gain calculation and recognition are not required.
The amount of the gain generally equals the CFC’s “Section 987 asset basis,” which represents the increase in the basis of the transferred assets attributable to appreciation in the QBU’s functional currency. Only gain, and not loss, is recognized, consistent with the longstanding treatment of inbound nonrecognition transactions under Section 367(b). Importantly, the Section 987 gain is recognized immediately before, rather than as part of, the inbound transaction. As a result, the gain does not increase the domestic acquiring corporation’s basis in the acquired assets.
The proposed regulations provide two methods for computing the Section 987 asset basis:
- A lookback method based on annual unrecognized Section 987 gain or loss computed under the simplified method of Section 1.987-10(e)(3) for taxable years ending during the 72-month period in which the election was in effect
- A method based on the transferor CFC’s excess asset basis determined under Section 1.367(b)-3
Applicability dates
The proposed regulations generally are proposed to apply to taxable years ending on or after the date the final regulations are filed with the Federal Register. Proposed Section 1.987-16 applies to transactions completed within taxable years of the domestic acquiring corporation ending on or after that finalization date. The pre-transition amortization rule in proposed Section 1.987-10(e)(5)(ii) applies to taxable years beginning after Dec. 31, 2024, and ending on or after Nov. 25, 2025.
Taxpayers may rely on the proposed regulations for a taxable year beginning after Dec. 31, 2024, and ending before the finalization date, provided that the taxpayer and all members of its consolidated group and Section 987 electing group consistently follow the proposed regulations for that year and all subsequent taxable years ending before finalization.
Special election procedures apply during the transition period. For taxable years beginning after Dec. 31, 2024, and ending on or before Dec. 31, 2026, the election generally is made on an original, timely filed return. An election for a taxable year beginning in 2025 may instead be made on an amended return filed by Oct. 15, 2027.
For a taxable year ending in 2027, the election statement generally must be filed with the IRS by Oct. 15, 2027, with a copy attached to the return. For later taxable years, the general rule requires the statement to be filed on or before the first day of the election year. A separate exception permits the election to be made on the original, timely filed return for the first taxable year in which the election becomes relevant.
Next steps
Taxpayers that own CFCs with Section 987 QBUs should identify their Section 987 electing groups, quantify pre-election (pre-transition) gain or loss pools, model the affected CFCs' Section 987 profiles, and evaluate the potential impact of any contemplated transactions involving those CFCs. Calendar-year taxpayers considering the election for 2025 through 2027 should make it on either an original or amended return filed no later than Oct. 15, 2027.
