Technology companies have finally achieved tax relief for domestic research and experimentation (R & E) expenses. Certain “small businesses” can elect to currently deduct them on their extended or superseding 2024 income tax returns and amending or filing an administrative adjustment request for their 2022 – 2023 return.

In order to achieve budget goals, the Tax Cuts and Jobs Act of 2017 included a provision requiring that research and experimental expenses incurred after December 31, 2021 be capitalized and amortized over a 60-month period. The plan was for the amortization requirement to be repealed before it became effective. From that time, technology companies have been lobbying Congress to restore the election to currently expense R & E expenses.

Finally, the expense election was restored for domestic R & E expenses by Section 70302 of the One Big, Beautiful Bill Act of 2025 (OBBBA), effective for tax years beginning after December 31, 2024. https://www.congress.gov/bill/119th-congress/house-bill/1

Most corporations may elect to deduct the unamortized balance of domestic R & E expenses that were previously capitalized for 2022 through 2024 over a one- or two-year period, starting for 2025. (OBBBA Section 70302(f)(2).)

Alternatively, certain small businesses that have average gross receipts of $31,000,000 or less for a taxable year beginning in 2025 may elect to amend their tax returns for 2022 – 2024 and currently deduct amounts that were previously capitalized and amortized. The election must be made by Monday, July 6, 2026. (Note the due date for filing an amended return supersedes that date. For example, a corporation that timely filed its 2022 income tax return, with no extension filed, on April 15, 2023 may not file an amended income tax return after April 15, 2026.) (OBBBA Section 70302(f)(1), Revenue Procedure 2025-28, Sections 3.02(1) and 3.03(3).) (Instead of filing amended income tax returns, partnerships file administrative adjustment requests (AARs).)

According to OBBBA Section 70302(f)(1)(A), the small business expense election should be made on an amended income tax return or an AAR. Many corporations still haven’t filed their 2024 income tax returns, with an extended due date of October 15, 2025. The American Institute of Certified Public Accountants and technology companies asked the IRS to allow them to make the election for 2024 on an originally-filed income tax return.

On August 28, 2025, the IRS issued Revenue Procedure 2025-28. https://www.irs.gov/pub/irs-drop/rp-25-28.pdf According to the Revenue Procedure, certain small business taxpayers may make the election to currently deduct R & E expenses on an originally-filed income tax return. (Rev. Proc. 2025-28, Section 3.03.) In addition, the IRS said that a six-month automatic extension of time to file is granted to any business that didn’t previously request one, and a business that previously filed a 2024 income tax return without electing to currently deduct R & E expenses may make the election by timely filing a superseding income tax return that includes the election. (Rev. Proc. 2025-28, Section 8.)

A business that deducts domestic R & E expenses on an original federal income tax return and complies with the requirements of Rev. Proc. 2025-28, Section 3.03 for all other applicable tax years will be deemed to have made a current-expense election. (Rev. Proc. 2025-28, Section 3.03(4).)

Instead of filing a change of accounting Form 3115, the taxpayer should attach a statement to the income tax return with similar information specified in the Revenue Procedure. (Rev. Proc. 2025-28, Sections 3.03(2) and 3.04.)

Taxpayers should consider the cost of preparing amended income tax returns and AARs, and that the IRS takes about a year to process them, when making the decision whether take to amended return/AAR route, including deducting the expenses currently on the 2024 income tax return, or simply deducting unamortized domestic R & E expenses on their 2025, or 2025 and 2026, income tax returns.

I highly recommend consulting with a qualified tax return preparer when implementing this change.
