How the OBBBA Revamp Impacts R&D Tax Deductions

Research and Experimental (R&E) expenditures are vital for fostering innovation across various industries. Historically, these expenses have played a significant role in incentivizing innovation through tax deductions, allowing businesses to lower their taxable income significantly.

The One Big Beautiful Bill Act (OBBBA), enacted on July 4, 2025, marks a pivotal shift by reinstating the immediate deduction of domestic Research and Experimental (R&E) expenses, a reversal of the Tax Cuts and Jobs Act (TCJA) changes of 2017. This legislation, under the new Internal Revenue Code (IRC) Section 174A, rejuvenates an essential incentive for U.S.-based innovation. However, it still imposes more stringent requirements for foreign R&E activities.

Defining R&E Expenses Research and Experimental expenses, often synonymous with research and development (R&D) costs, are broadly defined as costs incurred during the enhancement or development of a product, including software. Key expenses include:

  • Employee wages for research activities
  • Costs for materials and supplies used in research
  • Third-party contractor research services
  • Overhead costs for facilities and equipment, such as rent and utilities

The IRS's broad definition encourages diverse innovative activities across sectors.

The Historical Context of R&E Expensing Prior to 2022, businesses could either immediately deduct R&E expenses or amortize them over at least 60 months. This was financially advantageous for innovation-driven companies. However, post-TCJA amendments required R&E expenditures to be capitalized and amortized over five years domestically and 15 years internationally, increasing cash tax burdens significantly, particularly for startups and pre-revenue firms.

OBBBA's Impact Post-2024 With the OBBBA in effect for tax years starting after December 31, 2024, the landscape for domestic R&E has transformed significantly via Section 174A.

Domestic versus Foreign R&E Considerations

  • Domestic R&E Expenditures: Taxpayers may opt to permanently deduct 100% of these costs annually, restoring pre-2022 favorable treatment and encouraging U.S.-based research. Alternatively, amortizing over 60 months remains an option.
  • Foreign R&E Expenditures: These continue to require 15-year amortization, with no immediate recovery for unamortized foreign R&E upon asset disposition post-May 12, 2025. This distinction may drive multinationals to relocate research within U.S. borders for tax benefits.

Transitional Relief for 2022-2024 Expenses The OBBBA offers pathways for expediating deductions of domestic R&E costs from the 2022-2024 period under old TCJA guidelines starting the first tax year after December 31, 2024:

  • Full Expensing: Deduct the entire unamortized balance in 2025.
  • Two-Year Amortization: Deduct 50% of the balance in both 2025 and 2026.
  • Continued Amortization: Follow the original five-year schedule.
  • Retroactive Expensing for Small Businesses: Eligible businesses (with $31 million or less in gross receipts over three years) can amend returns for 2022-2024 for refunds, requiring alignment with R&D tax credit provisions (Section 280C(c)).

Intersection with Broader Tax Provisions These tax changes interact notably with net operating loss (NOL) rules, bonus depreciation, business interest limitations, and international taxes for larger enterprises. Holistic evaluation of these interplays is essential, especially as new deduction opportunities arise in 2025, presenting unique strategic tax planning prospects.

Adoption as an Accounting Change Treated as an automatic accounting method change, these transition rules simplify compliance, offering a significant cash infusion opportunity for affected businesses. The IRS released guidance via Rev Proc 2025-28 for implementing these changes by attaching a brief statement to returns, eliminating Form 3115 requirements.
