Businesses Regain Immediate Deduction for R&E Expenses

Mar 3, 2026 | Business, Newsletter, Tax

If your business conducts research or product development, a significant tax law change could unlock tax savings. The 2025 tax legislation, commonly known as the One Big Beautiful Bill Act (OBBBA), reinstated the ability to immediately deduct domestic research and experimental (R&E) expenses.

This change reversed a key provision of the Tax Cuts and Jobs Act (TCJA) that required businesses to capitalize and amortize domestic R&E expenses over five years and foreign R&E expenses over 15 years. As a result, you may have new tax-saving opportunities as you prepare your 2025 tax return and plan for 2026.

What the Change Means for Your 2025 Filing

Beginning with eligible 2025 expenses, businesses can once again deduct U.S.-based R&E costs in full in the year they’re incurred. This can significantly reduce taxable income and improve cash flow.

The law also provides flexibility for prior-year R&E expenses. You can potentially accelerate deductions that previously you would have had to spread over multiple years.

Strategies to Maximize R&E Tax Benefits

Businesses should consider the following when assessing R&E expenditures:

Amend returns for prior years. Small businesses (generally those with average annual gross receipts of $31 million or less over the past three years) may be able to apply the rule retroactively. If eligible, you can file amended returns for 2022, 2023 and/or 2024 to claim immediate deductions for domestic R&E expenses previously amortized and, potentially, receive a tax refund for those years. You must file the amended return(s) by July 4, 2026.

More quickly claim remaining deductions. Businesses of any size that capitalized and began amortizing R&E expenses in 2022, 2023 and/or 2024 can accelerate their deductions for the remaining unamortized balance. You can deduct it entirely on your 2025 return or split it ratably between your 2025 and 2026 returns, rather than continuing amortization over the original five-year period.

Bring research activities back onshore. The immediate deduction makes domestic research activities significantly more attractive from a tax perspective. While under prior law, U.S.-based R&E already benefited from shorter amortization periods, the difference between an immediate deduction and a 15-year amortization schedule for foreign research further strengthens the incentive to locate R&E activities in the United States.

Consider the research credit. A tax deduction reduces your taxable income, while a tax credit reduces your tax bill dollar-for-dollar and is generally more valuable. You may be eligible for the credit for “increasing research activities,” but fewer types of expenses qualify for the credit than for the R&E deduction. While you can benefit from both, you can’t receive a double tax benefit for the same costs.

The return of the immediate deduction for R&E expenses can bring planning opportunities for businesses. Contact the office for help determining what applies to your situation.
