The Impact of the OBBBA on R&E Tax Strategy for U.S. Businesses

Research and Experimental (R&E) expenses play a pivotal role in fostering innovation and development across various sectors. Historically, these expenditures have been incentivized through tax laws, enabling businesses to deduct them, thereby reducing their taxable income.

The One Big Beautiful Bill Act (OBBBA), enacted on July 4, 2025, permanently restores the privilege for businesses to instantly deduct domestic R&E expenditures, counteracting the Tax Cuts and Jobs Act (TCJA) of 2017's controversial revision. Under the newly introduced Internal Revenue Code (IRC) Section 174A, this key incentive supports U.S.-based innovation, yet retains tough capitalization rules for international R&E activities.

Defining R&E Costs - R&E expenses, often synonymous with R&D costs, typically cover expenditures tied to product development or enhancement, such as software creation. Specific examples encompass:

Employee wages linked to research tasks.
Research-related material and supply costs.
Expenses for contracted third-party research.
Overhead linked to R&E facilities and equipment, including rent, utilities, insurance, and repairs.

Broad IRS definitions of these expenditures aim to promote a spectrum of innovative efforts.

R&E Expense History - Prior to the TCJA amendments effective for tax years starting after December 31, 2021, businesses could either deduct R&E expenses in the incurred year or opt for capitalization and amortization over at least 60 months, enhancing cash flow for innovation-centric firms.

The TCJA's 2022 rule change necessitated the capitalization and five-year amortization of all R&E expenses domestically, and 15 years for foreign research. This shift imposed substantial cash tax burdens on businesses, notably startups and early-stage ventures incurring hefty R&D costs pre-revenue.

The OBBBA's Impact on R&E Expensing - Effective for tax years commencing after December 31, 2024, Section 174A of the OBBBA dramatically modifies domestic R&E incentives.

Domestic vs. Foreign Classification - The OBBBA distinctly categorizes research expenses by location:

Domestic R&E Expenditures: Taxpayers can fully and immediately deduct 100% of these expenses in the year they occur, reviving pre-2022 benefits to encourage domestic research. Alternatively, taxpayers may capitalize and amortize over at least 60 months, if preferred.
Foreign R&E Expenditures: The requirement to capitalize and amortize over 15 years for foreign research persists. The act prohibits instant recovery of any unamortized basis for abandoned foreign R&E post-May 12, 2025. This policy may prompt multinational entities to reconsider research sites to optimize tax benefits.

Strategies to Accelerate Amortized Costs - Transition relief under the OBBBA applies to R&E costs capitalized during 2022-2024 under TCJA rules. Taxpayers with unamortized domestic R&E costs from this period can accelerate deductions starting with the first tax year post-December 31, 2024:

Option 1: Full Expensing in 2025: Deduct the entire remaining unamortized balance of domestic R&E costs in the first tax year after December 31, 2024.
Option 2: Two-Year Amortization: Deduct the unamortized balance evenly over two years (50% in the 2025 tax year and 50% in 2026).
Option 3: Continued Amortization: Elect to sustain the amortization over the original remaining five-year timeframe.
Small Business Eligibility: Qualified small businesses (generally with average annual gross receipts of $31 million or less over three preceding tax years) have additional options:
- Retroactive Expensing via Amended Returns: Electing to retroactively apply full expensing rules to post-December 31, 2021 tax years by amending returns (e.g., for 2022, 2023, and 2024) to procure tax refunds based on prior rules. This election must occur by July 4, 2026, and coordinate with R&D tax credits (Section 280C(c)) requiring an R&D credit amount reduction.

Interaction with Other Tax Codes - New research and experimental expense provisions considerably interact with the tax code's other parts, like net operating loss (NOL), bonus depreciation, business interest expense limits, and international taxation for large corporations. It's crucial to evaluate these holistically. Taxpayers should model outcomes when considering other available 2025 deductions. These can dramatically reduce regular tax duties, unlocking strategic planning avenues.

Change in Accounting Practice - Transition regulations treat these as automatic accounting method changes, easing compliance. This deduction "catch-up" opportunity presents a significant cash influx for affected firms, offering instant relief from previous capitalization requirements. The IRS offers initial guidance through Rev Proc 2025-28, on executing changes via a return-attachment statement, bypassing Form 3115, Application for Change in Accounting Method.
