How the OBBBA Revitalizes U.S. R&D Tax Breaks

The landscape of Research and Experimental (R&E) tax regulations has seen a significant transformation, thanks to the new One Big Beautiful Bill Act (OBBBA). This legislation, effective from July 4, 2025, reestablishes immediate deductions for domestic R&E expenditures—reversing the 2017 Tax Cuts and Jobs Act’s (TCJA) mandates that required these expenses to be amortized over a set period.

R&E Expenses Defined
R&E costs, often synonymous with R&D expenses, encompass expenditures that encourage innovation. They include wages for personnel involved in research, material costs, third-party contractor fees for research services, and overhead costs such as rent and utilities. These costs are crucial for companies seeking to develop new or improved products, including software.

The IRS encourages a broad interpretation of qualifying expenses to promote innovation. Before TCJA's changes in 2022, businesses could choose to either deduct these expenses immediately or amortize them over time, helping companies with significant innovation investments achieve favorable cash flow benefits.

Impacts of TCJA Amendments
The TCJA required capitalization of R&E expenses over five years for domestic activities and fifteen years for international activities. This shift resulted in increased tax burdens, particularly impacting startups and pre-revenue enterprises by delaying the realization of tax benefits.

With the introduction of the OBBBA, though, businesses have regained the ability to immediately deduct their domestic R&E costs—revitalizing the incentive to invest in U.S.-based research. The legislation introduces IRC Section 174A, allowing 100% immediate expensing for domestic R&E expenditures, which positions the U.S. as a favorable environment for innovation.

Domestic vs. Foreign Research
The OBBBA maintains the stricter 15-year amortization requirement for foreign research-related expenses, compelling multinational corporations to reconsider their research strategies for optimal tax benefits. This disparity suggests that significant portions of innovation activities may gradually shift stateside.

Transition Options for Prior Amortized Expenses
For taxpayers who capitalized R&E expenditures from 2022-2024, the OBBBA provides varied options for expensing these costs: full expensing in 2025, a two-year amortization, or continuing the existing amortization schedule. Furthermore, eligible small businesses can retroactively apply full expensing going back to 2022 by amending previous returns to claim refunds.

Holistic Tax Planning Opportunities
The new R&E expense deductions are interlinked with other tax provisions such as net operating losses, bonus depreciation, and international tax considerations. Taxpayers should approach planning with a comprehensive view to maximize benefits. It's critical to model the outcomes of these deductions as part of strategic planning and regulatory compliance.

Streamlined Compliance
With IRS guidance under Rev Proc 2025-28, the OBBBA offers simplified compliance as businesses transition to the new rules, allowing "catch-up" opportunities through reduced administrative burdens. Companies should consider consulting with tax professionals to navigate these changes effectively and secure potential advantages offered by the act.
