The Impact of the OBBBA on R&D Tax Deductions

The realm of tax strategies plays a vital role in fostering innovation through Research and Experimental (R&E) activities. Businesses have long relied on tax treatment that allows for the deduction of R&E expenditures to spur innovation and reduce taxable income.

Enacted on July 4, 2025, the One Big Beautiful Bill Act (OBBBA) has reinstated the immediate deduction for domestic R&E expenditures, overturning the restrictive measures set by the 2017 Tax Cuts and Jobs Act (TCJA). This change, under the newly introduced Internal Revenue Code (IRC) Section 174A, provides strong incentives for businesses conducting R&D in the U.S., while maintaining stricter terms for foreign R&E activities.

Defining R&E Expenses
Also known as R&D costs, these include any expenditures related to product or software development. Typical expenses cover:

  • Employee wages for research-related activities.
  • Costs for materials and supplies used during research.
  • Expenses for third-party research services.
  • Overhead related to research facilities, including rent and utilities.

The IRS broadly defines these costs to promote a wide array of innovative efforts.

The Evolution of R&E Expensing
Pre-TCJA, businesses could either deduct R&E expenses immediately or opt for capitalization and amortization over 60 months. Post-TCJA from 2022 onwards, mandatory capitalization over five or fifteen years for domestic or foreign research, respectively, imposed hefty financial burdens, especially on startups and early-phase companies.

OBBBA's Favorable Revisions for Domestic R&E
Starting from the 2025 tax year, Section 174A allows for 100% immediate deduction of domestic R&E costs, restoring pre-2022 benefits and encouraging U.S.-based research. Businesses can also choose to capitalize these expenses if preferred.

Considerations for Foreign R&E
The previous requirement of 15-year capitalization for foreign R&E remains. Although this poses challenges for multinational firms, it may prompt reevaluations of where to conduct research to optimize tax benefits.

Accelerating Current Amortizations
The OBBBA introduces options for expenses capitalized between 2022 and 2024:

  • Full Expensing in 2025: Deduct all remaining domestic R&E costs immediately.
  • Two-Year Amortization: Spread deductions over two years, starting 2025.
  • Continued Amortization: Retain the original five-year schedule.
  • Eligible Small Businesses: Can opt for retroactive full expensing via amended returns to adjust previous tax years (2022-2024), coordinating with R&D credits per Section 280C(c).

Comprehensive Tax Planning
The updated provisions significantly interact with the tax code elements like net operating losses (NOLs) and business interest expenses. Hence, expert modeling is essential to align R&E deductions with other tax strategies, enhancing cash flow and minimizing liabilities.

Simplified Compliance through Accounting Changes
The IRS offers a streamlined approach for transitioning R&E expenses under Rev Proc 2025-28. Businesses can alter accounting methods seamlessly, potentially reclaiming considerable cash from prior capitalization mandates.
