Section 174 Domestic R&E Expensing in 2025: What’s Changed and How You Can Benefit

Section 174 reform under the One Big Beautiful Bill Act (OBBB) was a major turning point for companies heavily invested in R&E. 

As of the 2025 tax year, R&E expenses can be claimed immediately rather than being capitalized and amortized over several years. 

The OBBB introduced Section 174A, which separates foreign and domestic research. 

Domestic R&E expenses are eligible for immediate deduction, while foreign R&E is still subject to a 15-year capitalization under Section 174. However, there is still an option to capitalize and amortize domestic R&E if it makes more sense. 

Ultimately, the reform provides greater flexibility for domestic R&D, improving cash flow by eliminating the five-year spread. 

Section 174A also provides mechanisms for companies to amend returns for 2022 to 2024 to align with the update, enabling significant retroactive tax reductions on unamortized domestic R&E expenses. Alternatively, taxpayers can apply a change in accounting (using Form 3115) to transfer these expenses to the 2025 tax year. 

Bracing for Impact

Though the Section 174 reform is advantageous, it is also more nuanced. There is a distinct need to analyze deductions, credits, and how state law intersects with them. Planning is essential, and most companies will need to reexamine their tax strategy from every angle.

Since the change will affect taxable income, companies will need to reexamine their Section 41 base calculation, which must exceed a specified amount to be eligible for the federal R&D tax credit. 

The legislation also modified Section 280C. Now, taxpayers are required to reduce R&E expenses by the amount of their research tax credit. 

Speaking with a qualified tax professional experienced in research-heavy sectors can provide you with the advice you need to leverage Section 174 changes to their best advantage. 

Tax Planning Tips to Maximize the Benefits of Section 174

While Section 174 reforms mean that tax relief is on the horizon, proactive planning is essential to maximize the advantage. 

Case in point: there are significant issues with how Section 280C interacts with tax credits. Under the current regime, Section 280C prevents taxpayers from claiming a full deduction and a full tax credit for the same expenses. 

Now, companies must reduce the amount of the credit by the expenses claimed, dollar-for-dollar. Going forward, this isn’t so much of an issue. However, when reassessing previous tax years to claim retroactively, some complex calculations are required. 

Companies may choose to reduce their R&D credit to avoid having to reduce their R&E deduction. To summarize, for the 2025 tax year and onward, 174A allows immediate expensing of R&E costs, thereby reducing the R&D credit under 280C. 

Defining qualified research under the new rule

At its most basic, the new rule distinguishes between domestic and foreign research. The differences here, for tax purposes, are significant and warrant consideration when planning new projects or enhancements to current research. 

Documentation is critical

Research expense data must be captured immediately, even if categorization is unclear. R&D activities conducted outside the U.S. should be tracked separately from those conducted domestically to simplify filing. You may need to adjust your systems to accommodate separate tracking, storage, and documentation of R&D related expenses. 

Consider amending returns

You have two choices: amend returns from 2022 through 2024 for a retroactive adjustment or amortize them into 2025 or 2026. Analyze which option is more advantageous, particularly given the need to adjust tax credits.

280C considerations 

As mentioned above, the interaction between 280C and 174A must be carefully considered to ensure optimal tax results. 

Develop financial models based on various scenarios

Understanding the effects of various tax scenarios is essential, as each will affect cash flow, tax liability, and net losses. Timing is everything, and being able to visualize the outcome will provide a more accurate picture of the future. 

How Companies Can Benefit from Section 174A

Despite the complexities of the R&E expensing rules under the amended Section 174A, there are many benefits to consider, not the least of which is improved cash flow. Without the need to amortize R&E expenses over several years, companies can, as of the 2025 tax year, deduct the expenses immediately to reduce their tax burden. 

Companies that qualify can also amend their 2022 – 2024 returns and claim full deductions retroactively or bring them forward into 2025 – 2026. Qualification is limited to companies with annual gross receipts of less than $31 million in 2025. 

If there is a residual balance on a Section 174 amortization, it can be accelerated into 2025 returns rather than being spread out over future years. 

As a result of these new expensing rules, Section 41 R&D tax credits could become more valuable – being mindful, of course, of the need to reduce tax credits already received based on retroactive claims. 

Steps you can take immediately include the following:

• Analyze previously capitalized expenses between 2022 and 2024. Create modeling scenarios and choose whether it would be beneficial to bring those expenses into 2025 or split them over 2025 and 2026.

• Segregate foreign and domestic R&E expenses. Domestic expenses are now eligible for deduction, while foreign expenses still require 15-year amortization. Consider moving foreign R&E activities back to the U.S. to reduce costs and gain a tax advantage.
