Businesses have a narrow window to recover R&D tax deductions from prior years. Here are the top 3 things to know.
For many businesses, research and development expenses have been a source of frustration since 2022.
Under prior rules, companies were required to capitalize and amortize domestic research and experimental expenses over five years instead of deducting them immediately. That created cash-flow challenges for businesses investing in software development, product improvements, process innovation, engineering, testing, and other qualifying research activities.
The One Big Beautiful Bill Act changed that.
Beginning with tax years after December 31, 2024, many businesses can once again immediately deduct domestic R&D expenses. But for eligible small businesses, the bigger opportunity may be retroactive relief for 2022, 2023, and 2024.
That opportunity comes with a deadline.
For many eligible businesses, July 6, 2026 is the final date to make the retroactive election and pursue potential refunds. Some businesses may have an even earlier deadline depending on the statute of limitations for their prior-year returns.
Here are the top three questions businesses should be asking now.
1. What changed with R&D expensing?
The new law restored immediate expensing for domestic research and experimental expenses beginning in 2025. That means businesses with qualifying U.S.-based R&D activities may be able to deduct those costs in the year they are incurred instead of spreading the deduction over five years.
This can be a meaningful improvement for businesses that invest in:
- Software development
- Product design or improvement
- Engineering and testing
- Manufacturing or process improvements
- Technology integration
- New or improved internal systems
- Prototyping or experimentation
Foreign research expenses are still treated differently and generally remain subject to longer amortization rules.
For businesses planning ahead, this change may simplify future tax treatment and improve cash flow. But the more urgent issue is whether prior-year domestic R&D costs from 2022 through 2024 can be revisited.
2. Who may qualify for retroactive R&D relief?
Eligible small businesses may be able to apply the new domestic R&D expensing rules retroactively to tax years 2022, 2023, and 2024.
In general, this opportunity applies to businesses with average annual gross receipts of $31 million or less, calculated under the applicable small business rules. That gross receipts test can be more complicated than it sounds, especially when related entities, common ownership, partnerships, or controlled groups are involved.
A business should not assume it is ineligible just because one year exceeded $31 million or because it does not think of itself as a “research” company.
Many companies conduct qualifying R&D without calling it R&D. The activity does not have to involve a laboratory, a patent, or a new invention. It may include work done to improve products, processes, software, formulas, techniques, or performance.
The key question is whether the business incurred qualifying domestic research or experimental expenses during the affected years and whether it meets the eligibility rules for retroactive relief.
3. Why does the July 6, 2026 deadline matter?
The retroactive relief window is limited.
For many eligible businesses, July 6, 2026 is the deadline to file amended returns or take other required action to make the retroactive election. However, the deadline may be earlier if the normal refund claim statute of limitations expires first.
That is why timing matters.
A business that waits too long may lose the ability to recover deductions from prior years. After the window closes, capitalized R&D expenses from 2022 through 2024 may have to remain on their original amortization schedule, even if the business would otherwise have qualified for relief.
This is not a “look at it later” issue. Businesses need time to evaluate eligibility, review prior-year R&D expenses, coordinate the deduction with any R&D credits claimed, prepare amended filings if appropriate, and consider how the change impacts current and future tax planning.
What should businesses do now?
If your business capitalized domestic R&D expenses in 2022, 2023, or 2024, now is the time to review your options.
A strong review should answer four questions:
- Did the business incur qualifying domestic R&D or experimental expenses?
- Does the business meet the gross receipts and eligibility requirements?
- Would amended returns create a meaningful cash refund or tax benefit?
- How does retroactive expensing interact with any R&D tax credits already claimed?
The answer will not be the same for every business. In some cases, retroactive relief may create a significant refund opportunity. In others, the better strategy may involve current-year deductions, remaining unamortized costs, or future planning.
The important thing is to assess the opportunity before the deadline passes.

Frequently Asked Questions
What is the July 6, 2026 R&D tax deadline?
The July 6, 2026 deadline is the general deadline for many eligible small businesses to make a retroactive election to immediately expense certain domestic R&D costs from 2022, 2023, and 2024. Some businesses may face an earlier deadline if the statute of limitations for claiming a refund expires before July 6, 2026.
What changed under the One Big Beautiful Bill Act?
The OBBBA restored immediate expensing for many domestic research and experimental expenses beginning with tax years after December 31, 2024. It also created a retroactive relief opportunity for certain eligible small businesses that capitalized domestic R&D expenses in 2022, 2023, and 2024.
Who qualifies as an eligible small business for retroactive R&D relief?
In general, eligible small businesses must meet a gross receipts test of $31 million or less in average annual gross receipts, calculated under applicable tax rules. Related-party aggregation, ownership structure, and entity type can affect the analysis, so businesses should review eligibility carefully before assuming they do or do not qualify.
Does my business have to be a technology company to qualify?
No. R&D tax opportunities are not limited to technology companies. Manufacturers, construction-related businesses, engineering firms, software companies, product developers, and many other businesses may conduct qualifying research activities even if they do not describe the work as “R&D.”
Can a business amend prior-year tax returns for R&D expensing?
Yes, eligible businesses may be able to amend prior-year tax returns or take other required filing steps to apply immediate expensing to qualifying domestic R&D costs from 2022 through 2024. The filing approach depends on the entity type, prior filings, credits claimed, and applicable IRS procedures.
