OBBBA Section 174 Small Business Election: How to Refund 2022-2024 R&D Taxes Before July 6, 2026

A small software business in Provo paid roughly $400,000 in extra federal tax across its 2022, 2023, and 2024 returns. The business wasn't more profitable than expected. It just had to capitalize its domestic engineering payroll under the TCJA version of IRC §174 and amortize it over five years instead of deducting it immediately. Founders across the country lived this story for three filing seasons. The One Big Beautiful Bill Act ended it on July 4, 2025, and for qualified small businesses the OBBBA Section 174 small business election turns the prior three returns into a refund. The filing window closes on July 6, 2026.

The IRS published the procedural roadmap in Revenue Procedure 2025-28 on August 28, 2025. It is unusually generous guidance, but the mechanics are not casual. A small business that wants the refund has to thread an accounting method change, amended returns, and a recoupling calculation with the §280C(c) R&D credit, all inside a single filing season. OBBBA also rewrote Section 1202 QSBS and made 100% bonus depreciation permanent. The §174 fix is the line item with the tightest deadline.

OBBBA Section 70302 added a new IRC §174A, effective for tax years beginning after December 31, 2024. Domestic research or experimental expenditures are immediately deductible in the year paid or incurred. A taxpayer can also elect to capitalize and amortize the cost over a chosen period of 60 months or more, or over 10 years under §59(e), but the default is current deduction. Foreign R&E stays under the old §174 with the 15-year amortization period intact, so multinational R&D groups still need to track the geographic split.

For prior years, OBBBA did two things. It opened a retroactive door for small businesses, and it gave everyone else an acceleration election for the remaining unamortized balance. Both elections close on July 6, 2026, one year after the bill was signed.

The retroactive election is limited to a 'qualified small business taxpayer,' defined by reference to the §448(c) gross receipts test. For tax years beginning in 2025, the test is met if average annual gross receipts for the prior three years (2022, 2023, and 2024) do not exceed $31 million, indexed each year for inflation. The test aggregates gross receipts across the §448(c) controlled group and across single-employer affiliates, so the founder who runs three separate LLCs cannot stack each entity under its own cap.

For an eligible taxpayer, the election applies §174A retroactively to every tax year beginning after December 31, 2021. That is 2022, 2023, and 2024 for almost every calendar-year filer. Capitalized §174 amounts from those years are deducted in the year originally paid. Any resulting net operating losses flow through the amended returns, and the refund returns with statutory interest under §6611.

Rev. Proc. 2025-28 gives the small business two filing paths. The first is to amend the 2022, 2023, and 2024 returns inside the §6511 statute of limitations. The election is made on each amended return, the §174 capitalization is reversed, the §174A deduction is taken in the year originally paid, and any R&D credit is recomputed under the new §280C(c). The second path is an accounting method change for a taxpayer that has not yet filed the 2024 return. A statement in lieu of Form 3115 is filed with the original 2024 return, §174A is adopted retroactively, and a §481(a) catch-up adjustment runs through 2024 to capture the prior years' difference. The IRS granted a six-month automatic filing extension specifically so a superseding 2024 return can include the election.

Whichever path you choose, every domestic R&E year in the window has to go the same way. You cannot apply §174A retroactively to 2024 only. It is all three years or none for 2022 through 2024. The same is true for the deadline. A return amended one day after July 6, 2026 forfeits the position the prior amendments preserved.

Most software, biotech, and manufacturing businesses that capitalized §174 also claimed the §41 research credit on the same expenses. The reduced-credit election under §280C(c) coordinates the credit with the underlying deduction. When §174 deductibility moves from amortized to immediate, the §280C calculation moves with it for every year inside the retroactive election. Skipping the recomputation is the most common drafting error in the amended returns I have reviewed since the procedure dropped. The gross credit doesn't change, but the §280C(c) addback (and therefore the net federal refund) does. Rev. Proc. 2025-28 explicitly requires the recomputation, and IRS examiners running these claims will check for it.

For taxpayers above the $31 million gross receipts threshold, the retroactive door is closed. OBBBA's transition rule instead lets the unamortized §174 balance from 2022 through 2024 be deducted in full on the 2025 return, or ratably across 2025 and 2026. The election sits on the 2025 return as a method change for §481 purposes, but on a cut-off basis with no §481(a) catch-up adjustment. The math is just the remaining unamortized balance, accelerated. A C corporation sitting on $4 million of unamortized 2022 through 2024 §174 capitalizations can drop the full $4 million into 2025 or split it 50/50 across 2025 and 2026. Which one is right depends on projected 2025 and 2026 taxable income, §163(j) interest limits, and any NOL constraints.

The federal refund is the headline, but the state picture varies widely. California never conformed to TCJA's §174 capitalization, so domestic R&E has always been immediately deductible at the state level there. That means California offers no retroactive state refund, only the federal one. Pennsylvania and Tennessee decoupled from TCJA §174 for their corporate income tax and end up in the same spot. Utah, by contrast, uses federal taxable income as its starting point and picks up §174A automatically, which is where the Utah refund column in the worked example above comes from.

Texas is an outlier in the opposite direction. The Texas franchise tax under Tex. Tax Code §171.0001 is fixed to a 2007 version of the IRC for its cost of goods sold deduction, so Texas never picked up TCJA §174 capitalization and is not picking up §174A either. New York, Illinois, and most rolling-conformity states adopted §174A automatically when their conformity statutes refreshed. The right answer for any specific client depends on the apportionment factor across states and whether a federal refund is worth the multi-state amended-return cascade that follows. For a multi-state SaaS company with serious R&D credits, the answer is almost always yes. For a single-state filer in California, the federal refund is the whole prize.
