San Francisco Tax Preparation / CPA: Streamlined Procedures Provided for Research and Experimental Expenditure Elections and Accounting Method Changes (Rev. Proc. 2025-28)

Revenue Procedure 2025-28 instructs taxpayers on how to make various elections, file amended returns or change accounting methods for research or experimental expenditures as provided under the One, Big, Beautiful Bill Act (P.L. 119-21). The revenue procedure also provides transitional rules, modifies Rev. Proc. 2025-23, and grants an extension of time for partnerships, S corporations, C corporations, individuals, estates and trusts, and exempt organizations to file superseding 2024 federal income tax returns.

Background

The Tax Cuts and Jobs Act (TCJA) required taxpayers to capitalize and amortize specified research or experimental expenditures over 5 years for domestic research or 15 years for foreign research, beginning with taxable years after December 31, 2021. The OBBB Act, enacted July 4, significantly modified these rules by adding new Code Sec. 174A to allow immediate deduction of domestic research or experimental expenditures while retaining the capitalization and amortization requirements only for foreign research expenditures.

Code Sec. 174A provides that domestic research or experimental expenditures paid or incurred in taxable years beginning after December 31, 2024, are generally deductible when paid or incurred. Alternatively, taxpayers may elect under Code Sec. 174A(c) to capitalize these expenditures and amortize them over at least 60 months, beginning when the taxpayer first realizes benefits from the expenditures.

The OBBB Act also provides transition relief, including retroactive application options for small business taxpayers and methods for recovering previously capitalized amounts.

Code Sec. 280C(c)(2) Elections and Revocations

Eligible small business taxpayers may make late elections under Code Sec. 280C(c)(2) to reduce their research credit in lieu of reducing their deductible research expenditures or revoke prior Code Sec. 280C(c)(2) elections. These are available for applicable taxable years where the original return was filed before September 15, 2025.

Elections are made by adjusting the research credit amount on amended returns, attaching amended Form 6765 marked with the appropriate revenue procedure reference, and including required declarations.

Code Sec. 174A(c) Election Procedures

For domestic research or experimental expenditures paid or incurred in taxable years beginning after December 31, 2024, taxpayers may elect to capitalize and amortize these expenditures under Code Sec. 174A(c). The election must be made by the due date of the return for the first applicable taxable year by attaching a statement specifying the amortization period (not less than 60 months) and the month when benefits are first realized.

Automatic Consent for Accounting Method Changes

Rev. Proc. 2025-28 modifies Rev. Proc. 2025-23 to provide automatic consent procedures for various accounting method changes related to research expenditures:

changes to comply with Code Sec. 174 for expenditures paid or incurred before January 1, 2025;

changes to implement the new Code Sec. 174A deduction or amortization methods for expenditures paid or incurred after December 31, 2024; and

changes to comply with modified Code Sec. 174 requirements for foreign research expenditures.

For the first taxable year beginning after December 31, 2024, taxpayers may use statements in lieu of Form 3115 for certain accounting method changes, with simplified procedures and waived duplicate filing requirements.

Small Business Retroactive Election

Small business taxpayers meeting the Code Sec. 448(c) gross receipts test (average annual gross receipts of $31,000,000 or less for 2025) may elect to retroactively apply Code Sec. 174A to domestic research or experimental expenditures paid or incurred in taxable years beginning after December 31, 2021. This election allows eligible taxpayers to either deduct these expenditures in the year paid or incurred or elect the Code Sec. 174A(c) amortization method.

The election is made by attaching a statement entitled “FILED PURSUANT TO SECTION 3.03 OF REV. PROC. 2025-28” to the taxpayer’s original or amended federal income tax return for each applicable taxable year. The statement must include the taxpayer’s identification information, declarations regarding tax shelter status and gross receipts test compliance, and specification of the chosen method.

Elections made on amended returns must be filed by July 6, 2026, subject to the normal statute of limitations under Code Sec. 6511 for refund claims.

Relief for Previously Filed Returns

Rev. Proc. 2025-28 grants automatic six-month extensions for eligible taxpayers to file superseding returns for 2024 taxable years. This relief is available to taxpayers who filed returns before September 15, 2025, without extensions, and need to make elections or method changes provided by the revenue procedure.

The extension applies to partnerships, S corporations, C corporations, individuals, trusts, estates, and exempt organizations with 2024 taxable years ending before September 15, 2025, where the original due date was before September 15, 2025.

Effective Date

Most provisions of Rev. Proc. 2025-28 are effective August 28, 2025. The modified automatic change procedures apply to Forms 3115 filed after August 28, 2025, with transition rules for taxpayers who properly filed duplicate copies before November 15, 2025.
