New R&D Tax Credit Changes Explained: Save Your Business Thousands
The R&D tax credit changes from the One Big Beautiful Bill Act of 2025 give businesses a real opportunity to save thousands in tax liability. Starting in 2025, businesses can again immediately and fully deduct domestic research and development expenses in the year they occur. This policy reversal provides substantial financial relief to companies investing in innovation.
The Section 174 tax treatment has changed fundamentally with the creation of new Section 174A, bringing back the pre-TCJA expense treatment for domestic R&D activities. Businesses now have options – they can choose immediate expensing or elect to amortize costs over at least five years. The financial impact is significant, with the average R&D tax credit typically ranging from 6-10% of qualified costs.
We see particular value in the retroactive relief provisions for small businesses with average annual gross receipts under $31 million for tax years 2022-2024. This allows eligible companies to file amended returns or claim catch-up deductions. We’ll walk you through exactly how these changes affect your business, the steps to maximize your tax savings, and strategic approaches to optimize both the R&D deduction and credit benefits.
What the One Big Beautiful Bill Act Changed

On July 4, 2025, President Trump signed the One Big Beautiful Bill Act (OBBBA) into law. The changes affect how your business handles research and development expenses. We see these modifications as a reversal of Tax Cuts and Jobs Act provisions that created cash flow challenges for innovative companies since 2022.
Restoring full expensing for domestic R&D
The most impactful change restores immediate expensing for domestic research expenditures. Your business can now fully deduct qualified domestic R&D costs in the year they occur, starting with tax years beginning after December 31, 2024. This eliminates the mandatory five-year capitalization and amortization requirements that had been in place since 2022.
We find this particularly beneficial for businesses investing in innovation. The OBBBA also creates permanent treatment for software development costs as R&E expenditures. Technology companies and startups no longer face uncertainty about classifying these expenses.
Section 174A vs. old Section 174 rules
Rather than simply reverting to old rules, Congress created new Section 174A with enhanced flexibility. Immediate expensing becomes the default option, but your business retains the choice to capitalize and amortize these costs over at least 60 months.
We notice a key difference from old Section 174 rules regarding when amortization begins. Previously, amortization started at the midpoint of the tax year when expenses occurred. Under Section 174A, companies choosing amortization can begin in the month they “first realize benefits” from the expenditures.
The law introduces an optional 10-year write-off for domestic R&D costs, providing another planning opportunity.
Why foreign R&D still follows 15-year amortization
Despite favorable changes for domestic research, foreign R&D expenditures must still be capitalized and amortized over 15 years. This approach creates clear incentives for conducting research activities within the United States rather than overseas.
We see this contrast between immediate domestic expensing and required foreign amortization as a deliberate policy choice to promote U.S.-based innovation. Multinational organizations might consider shifting research activities to domestic locations or engaging U.S.-based contract researchers to maximize tax benefits.
R&D Expense Treatment Options That Work for Your Business

Your business now has three distinct ways to handle R&D expenses under the One Big Beautiful Bill Act. Each option offers different benefits depending on your company’s financial situation.
Option 1: Take the full deduction with Section 174A
Section 174A lets you deduct all domestic research and experimental costs in the year you pay them. This option maximizes your cash flow and works best for companies with fluctuating R&D spending. The qualifying expenses include more than most businesses realize – wages for R&D employees, research supplies and materials, contractor payments at 100% of contract value, and software development costs.
Option 2: Spread costs over 60+ months
You can elect to capitalize and amortize domestic R&D costs over at least 60 months instead of taking the immediate deduction. The amortization starts in the month you first see benefits from the research – not at the tax year midpoint like the old rules required. This election helps companies dealing with alternative minimum tax issues or Section 163(j) income limitations.
Option 3: Use the 10-year write-off
Under Section 59(e) amendments, you can elect to deduct domestic R&D costs ratably over 10 years starting with the expenditure year. Unlike the 60-month choice, you can make this election annually for maximum flexibility.
Relief for 2022-2024 expenses you already capitalized
For R&D costs you’ve already capitalized from previous years, you have three paths:
- Full deduction: Claim your entire remaining balance in 2025
- Two-year spread: Take 50% in 2025 and 50% in 2026
- Continue current schedule: Keep your original five-year amortization
Small businesses with average gross receipts of $31 million or less for 2022-2024 can apply Section 174A retroactively by filing amended returns through July 6, 2026. This retroactive election delivers immediate cash flow through tax refunds.
How to Claim the R&D Tax Credit in 2025 and Beyond

Your business needs to meet specific qualification criteria and maintain proper documentation to successfully claim the R&D tax credit. With Form 6765 changes coming in 2025, smart preparation now sets you up for success.
Understanding the four-part test
Your R&D activities must satisfy all four parts of the IRS test to qualify for the credit:
- Permitted Purpose: Research must aim to develop or improve a business component’s function, performance, reliability, or quality.
- Technological in Nature: Activities must rely on principles of engineering, computer science, biological science, or physical science.
- Elimination of Uncertainty: You must be attempting to resolve uncertainty about capability, method, or design.
- Process of Experimentation: You must evaluate alternatives through modeling, simulation, or systematic trial and error.
The Phoenix Design Group ruling made clear that general complexity or design iteration doesn’t automatically qualify – you must identify specific technical challenges not readily resolvable using existing knowledge.
Section 280C election: full vs. reduced credit
You must make the Section 280C election on your original timely filed return (including extensions). This decision affects how you treat R&D expenses:
- Full Credit Option: Claim the entire credit but reduce Section 174A deductions by the credit amount
- Reduced Credit Option: Claim approximately 87% of the credit (credit minus credit × 21% corporate tax rate) but keep full deductions
Once made, this election is irrevocable for that tax year. Most C Corporations find both methods result in identical tax liability.
Updated Form 6765 requirements
Section G of Form 6765 becomes mandatory for most taxpayers in 2026. This section requires:
- Identification of business components accounting for 80% of QREs or your top 50 components
- Breaking down qualified wages into categories of direct performance, supervision, and support
- Detailing the specific information being sought for discovery
For 2025, Section G remains optional, giving you time to prepare for the new requirements.
Documentation and substantiation tips
Contemporaneous documentation is critical – retroactive creation significantly weakens your claim. We recommend maintaining:
- Technical documentation identifying specific uncertainties at project outset
- Records showing process of experimentation with alternatives evaluated
- Time tracking for employee activities on qualifying projects
- Supply receipts with allocation methodology
- Contracts and detailed invoices for contractor research
A simple general ledger line item saying “research expenses” is insufficient. Your documentation should connect expenses to specific qualified research activities at the business component level to establish nexus.
Strategic Planning for Businesses
Smart tax planning for the R&D tax credit changes can save your business thousands. We recommend these strategic approaches to maximize your benefits while maintaining compliance.
Evaluating deduction vs. credit optimization
The interaction between R&D tax credits and Section 174A deductions demands careful modeling. With the restored reduction requirement, companies must evaluate whether making the Section 280C election to reduce the credit rather than taking the deduction would provide better overall tax results. Moreover, businesses should develop multiple financial models based on different elections and timing strategies to understand the range of impacts on cash flow, NOLs, and overall tax liability.
Amending past returns for retroactive benefits
Small businesses should immediately evaluate whether they qualify for retroactive relief and assess the potential benefits of amending returns for 2022 through 2024. Effective June 18, 2024, the IRS waived two documentation requirements for R&D credit refund claims, now requiring only: identification of business components, research activities performed, and a breakdown of qualified expenses. This change simplifies the amendment process considerably.
Preparing for 2026 mandatory reporting
Section G of Form 6765 is optional for tax year 2025 but becomes mandatory in 2026. Exceptions exist for Qualified Small Businesses electing the payroll tax credit or taxpayers with QREs ≤ $1.5M and gross receipts ≤ $50M. Use 2025 as your preparation year to:
- Map business components to R&D projects
- Standardize activity narratives tied to qualification criteria
- Tag QREs at source to wages/supplies/contract research
Small business considerations under Section 174A
Does your business have average annual gross receipts under $31 million? You can elect to retroactively apply Section 174A to domestic R&D expenditures from 2022-2024. The deadline is July 6, 2026, or your statute of limitations date—whichever comes first. This election must include retroactive application of Section 280C(c) conforming amendments.
Conclusion
The R&D tax credit changes brought by the One Big Beautiful Bill Act represent a significant win for businesses investing in innovation. After years of mandatory capitalization, companies can finally return to immediate expensing of domestic research costs starting in 2025. This shift alone could save your business thousands in tax liability while improving cash flow.
Beyond the default immediate expensing option, the creation of Section 174A offers unprecedented flexibility. Your business can now choose between full deduction, 60+ month amortization, or even the optional 10-year write-off depending on your specific financial situation. Small businesses benefit particularly from retroactive relief provisions, allowing eligible companies to file amended returns for 2022-2024 by July 6, 2026.
Companies must remember that foreign R&D expenditures still require 15-year amortization. This stark contrast clearly incentivizes keeping research activities domestic, potentially reshaping how multinational corporations allocate their R&D resources.
Strategic planning becomes essential when maximizing these new opportunities. Careful evaluation of the Section 280C election, proper documentation of qualified research activities, and preparation for the upcoming mandatory Form 6765 requirements will determine how much your business actually saves. Businesses should use 2025 as a preparation year before the stricter reporting requirements take effect in 2026.
These legislative changes signal strong government support for domestic innovation and technological advancement. We encourage businesses of all sizes to thoroughly assess their R&D activities against the four-part test and work with qualified tax professionals to optimize both deductions and credits under these new rules. Undoubtedly, companies that act quickly to understand and implement these changes stand to gain significant competitive advantages through substantial tax savings in the years ahead.
