Why Your Section 174 Capitalization Strategy Might Be Wrong [Expert Guide]
Section 174 capitalization requirements will soon revolutionize. Businesses can write off all their domestic research and experimental costs in the same year starting 2025. This change reverses the five-year amortization rule from 2022.
Many businesses still use outdated or flawed strategies that could rob them of valuable tax benefits. The One Big Beautiful Bill Act brings Section 174A, letting taxpayers write off all domestic R&E expenditures for tax years after December 31, 2024. Small businesses that earn $31 million or less yearly can apply these changes back to tax years after December 31, 2021. This opens up chances for amended returns and refunds that companies might miss.
The law changes Section 280C too. Now domestic R&E expenditures must be reduced by the research credit amount. This key shift brings new tax planning needs for businesses that claim R&D credits with Section 174 deductions. Your current capitalization approach needs a fresh look, whether you stick with amortizing 2022-2024 Section 174 costs or switch to the new rules.
Let us help you learn about the changing Section 174 capitalization rules and check if your strategy lines up with these tax law updates.
Understanding the Evolution of Section 174

The history of section 174 capitalization shows how tax policy has changed toward research and breakthroughs. You should know these changes to make your tax strategy work better.
From immediate expensing to TCJA amortization
Businesses since 1954 could deduct qualified research and experimental (R&E) expenditures right away in the same year. Companies also had the choice to spread these costs over at least 60 months. This business-friendly approach helped promote breakthroughs in many industries.
The Tax Cuts and Jobs Act (TCJA) altered this setup completely. All taxpayers had to capitalize R&E expenditures and spread them over five years for domestic research and 15 years for foreign research starting in 2022. The TCJA made software development costs part of section 174’s scope.
Impact of the One Big Beautiful Bill Act
President Trump’s signature on the “One Big Beautiful Bill Act” (OBBBA) on July 4, 2025, brought much-needed relief through new Section 174A. Businesses can now deduct domestic R&E expenditures in the same year starting January 1, 2025. Foreign R&E expenditures still must be spread over 15 years.
The law gives multiple accounting choices for domestic R&E. Businesses can expense costs right away under Section 174A(a) or choose to capitalize under Sections 174A(c) or 59(e). The OBBBA also tells companies how to handle costs they already capitalized from 2022-2024.
Why the 2025 changes matter now
These changes need your attention right now, even though they start in 2025. Companies must choose what to do with their leftover R&E costs from 2022-2024. Most can either deduct everything in 2025 or split it between 2025 and 2026.
Small businesses that make $31 million or less yearly get special help. They can go back and expense costs by fixing their 2022-2024 returns. The IRS explained how to do this in Revenue Procedure 2025-28.
Your business should quickly review whether fixing old returns or taking bigger deductions in 2025-2026 fits better with your tax plans and expected income.
What the New Section 174A Rules Really Mean

The most important aspect of new section 174 capitalization provisions completely changes how R&E taxes work. Let’s get into what these changes mean for businesses.
Immediate expensing for domestic R&E
Section 174A brings back immediate expensing for domestic research and experimental expenditures. We focused on letting businesses fully deduct domestic R&E costs in the year they spend them for tax years starting after December 31, 2024. This change gives businesses better cash flow than the mandatory five-year capitalization they’ve dealt with since 2022.
Continued amortization for foreign R&E
Foreign R&E expenditures face tougher TCJA rules, even though domestic R&E gets better treatment. These costs need capitalization and amortization over 15 years. On top of that, Section 174(d) blocks quick recovery of unamortized foreign R&E costs when property gets disposed of, retired, or abandoned.
Optional elections under Section 174A(c) and 59(e)
Businesses have flexibility through two different methods, even with immediate expensing back:
- Section 174A(c) Election: You can choose to capitalize domestic R&E costs and amortize them over at least 60 months. This starts when you first see benefits.
- Section 59(e) Election: You also have the option to amortize domestic R&E costs evenly over 10 years.
You must make these elections by your tax return due date, including extensions. They apply now and in future years unless you get permission to change.
Software development and Section 174A(d)(3)
Software development costs stay classified as R&E expenditures under these rules. This means you can immediately expense domestic software development, but foreign software development needs 15-year amortization. Section 174A(d)(3) keeps the TCJA’s approach but adds the great benefit of immediate deductions for domestic work.
Why Your Current Capitalization Strategy Might Be Flawed
Businesses still need to adjust their section 174 capitalization strategies based on recent law changes. You might be missing out on valuable tax benefits.
Problems with updated Section 174 capitalization rules
Your current strategy might not account for OBBBA changes that allow immediate expensing of domestic R&E costs starting in 2025. Companies that set up five-year amortization systems now need completely different tracking methods. The rules get even more specific for software development costs under Section 174A(d)(3).
Section 280C implications you might miss
OBBBA changed Section 280C(c)(1), which now asks businesses to lower their domestic research cost deductions by the claimed research credit amount. You must apply this coordinating provision retroactively if you choose retroactive expensing. Tax uncertainty in 2022-2024 led many taxpayers to skip reduced credit amounts because they weren’t sure how disallowance worked with capitalized research costs.
Missing retroactive deduction chances
Small businesses with average annual gross receipts under $31 million can opt for retroactive treatment until July 4, 2026. This could mean refunds that many companies don’t know about.
Tax and cash flow modeling gaps
Tax projections across multiple years help you compare full expensing versus amortization. AMT calculations, business interest limits under Section 163(j), and state tax rules need careful analysis. Companies might miss chances to optimize quarterly payments without proper modeling.
How to Fix Your Section 174 Capitalization Approach

The OBBBA has revolutionized section 174 capitalization, making a well-planned approach vital for tax optimization. Here’s how you can adjust your strategy:
Should you amend or defer?
Small businesses need to check their potential retroactive relief benefits right away. Businesses that qualify (under $31 million average gross receipts) can get refunds by amending their 2022-2024 returns. Another option is to speed up remaining unamortized amounts into 2025 or split them between 2025-2026. Your best path depends on weighing the permanent tax cost of reduced R&D credits against timing benefits.
Make R&D tax credits work together
You should map out how R&D credits interact with Section 174A deductions carefully. The restored Section 280C reduction requirement means you need to review whether choosing reduced credit instead of reduced deduction works better. A centralized system that tracks R&D activities becomes vital.
State taxes and SALT effects matter
States handle Section 174 conformity differently. Some states automatically follow federal changes, while others stick to fixed-date conformity or completely separate approaches. Keep track of these differences to avoid surprises and find planning opportunities.
Get partnerships and flow-through entities ready
Partnerships must use administrative adjustment requests (AARs) instead of simple amended returns. Pass-through entities should analyze immediate deductions versus deferral based on their owners’ individual tax rates.
Follow Rev. Proc. 2025-28 guidelines
Rev. Proc. 2025-28 shows you how to handle accounting method changes and election statements. Automatic six-month extensions let you file superseding returns with proper elections if you’ve already submitted 2024 returns.
Conclusion
Tax rules are changing for businesses doing research and development. The change in Section 174 capitalization rules marks a key moment that needs quick action to review tax strategies. The One Big Beautiful Bill Act brings big changes to R&E tax treatment through new Section 174A. Companies can now fully expense domestic research costs starting in 2025. The 15-year amortization rule stays in place for foreign expenditures.
Small businesses can benefit by a lot from retroactive relief options. Many might miss this chance. The connection between Section 174A deductions and R&D tax credits needs careful review under the restored Section 280C rules. You’ll probably need to revise your current approach to get the most tax benefits.
You need to act fast. The main changes start in 2025, but you must decide now about unamortized costs from 2022-2024. Your business should choose between fixing past returns or pushing deductions to future years based on expected income and tax situation.
State tax rules add more complexity that could affect your overall tax position. It also brings special challenges for partnerships and flow-through entities when implementing these changes.
The switch back to immediate expensing for domestic R&E costs brings welcome relief after years of required capitalization. But this relief comes with new planning challenges and chances. Companies that act now to review their Section 174 capitalization strategies will end up in better positions as these tax law changes roll out.
Key Takeaways
The Section 174 tax landscape is undergoing major changes that could unlock significant savings for businesses engaged in R&D activities. Here are the critical insights every company needs to understand:
• Domestic R&E expensing returns in 2025: The One Big Beautiful Bill Act allows immediate deduction of domestic research costs starting January 1, 2025, reversing the mandatory five-year amortization rule.
• Small businesses can claim retroactive refunds: Companies with under $31 million average gross receipts can amend 2022-2024 returns by July 4, 2026, to claim immediate expensing and generate potential refunds.
• Foreign R&E still requires 15-year amortization: While domestic research enjoys favorable treatment, foreign R&E expenditures must continue following the stricter TCJA capitalization rules.
• Section 280C creates new R&D credit coordination requirements: Domestic research deductions must now be reduced by claimed research credits, requiring careful planning between Section 174A benefits and R&D tax credits.
• State conformity varies significantly: Different states handle Section 174 changes differently—some automatically adopt federal rules while others maintain separate approaches, creating compliance complexity.
The window for optimizing your Section 174 strategy is narrow. Companies should immediately evaluate whether to amend past returns or accelerate remaining unamortized costs into 2025-2026, while carefully coordinating with their R&D credit strategy to maximize overall tax benefits.
