Recent tax law changes now allow small and mid-sized businesses to retroactively reverse the mandatory five-year amortization of domestic R&D expenses incurred between 2022 and 2024. Eligible companies with average gross receipts under $31 million can amend prior returns to restore full, immediate expensing, potentially unlocking significant tax refunds. However, this planning window is narrow, as businesses must file their amended returns by the July 6, 2026 deadline to capture these benefits.
Over the past few years, the R&D tax credit has undergone a series of volatile changes that left many businesses uncertain about how and when they can benefit.
What started with the Tax Cuts and Jobs Act (TCJA), introduced a requirement to capitalize and amortize R&D costs over five years. This effectively "delayed" deductions, leading to higher taxable income and tighter cash flow beginning in 2022.
However, the recently enacted One Big Beautiful Bill Act (OBBBA), paired with new IRS guidance, has created a rare "second chance" for businesses to reclaim those lost deductions. But for small and mid-sized businesses, this window is closing fast.
When the original Section 174 capitalization rules took effect, businesses were forced to spread R&D expenses:
- 5 years for domestic research
- 15 years for foreign research
This significantly reduced the immediate cash-flow value of innovation. Under the OBBBA and IRS Rev. Proc. 2025-28, eligible businesses can now choose to retroactively reverse that treatment.
For eligible companies, this "Small Business Retroactive" (SBR) election means:
- Amending returns for tax years 2022 through 2024.
- Reversing prior capitalization of domestic R&D costs.
- Returning to full expensing (100% deduction) in the year the costs were incurred.
- Ability to change previously elected 280C treatment
Who Qualifies for This Opportunity?
The IRS has specifically carved out this retroactive relief for small and mid-sized businesses. To qualify for the retroactive SBR election, a company generally must:
- Average annual gross
- Have incurred domestic
Average annual gross receipts of $31 million or less over the 2022–2024 period).
Have incurred domestic R&D expenses that were previously capitalized.
The July Deadline: July 6, 2026
This is not a "soft" target. The deadline to file amended returns and make the retroactive election is July 6, 2026.
Missing this deadline could mean:
- Missed Refunds: Forfeiting immediate tax refunds from the 2022 and 2023 tax years.
- Forfeited Elections: Missing the chance to make a late Section 280C(c) election, which can optimize the value of the R&D credit itself.
Additional Planning Opportunities
Even if you choose not to amend prior years, the OBBBA has permanently changed the landscape for 2025 and beyond:
- If the retroactive election is not made, the taxpayer may still recover the remaining unamortized domestic Section 174 amounts, either deducting the full balance in 2025 or deducting it equally over 2025 and 2026.
- Immediate Expensing is Back: Domestic R&D costs no longer require capitalization for tax years beginning after Dec 31, 2024.
- Alignment: You can now align your R&D credit (Section 41) with your R&D deduction (Section 174A) in the same year, simplifying your tax strategy.
Why Action is Needed Now
We are seeing many businesses that capitalized R&D costs between 2022 and 2024 sometimes unnecessarily resulting in significant dollars left on the table. Because this involves amending prior-year returns, the documentation requirements are higher than ever. The IRS now expects business-component-level detail to support these claims.
