What Changed: R&D Expenses Are Immediately Deductible Again
For decades, businesses could immediately deduct their research and development (R&D) expenses in the year they were incurred. That changed in 2022, when a provision of the Tax Cuts and Jobs Act (TCJA) kicked in requiring businesses to amortize R&D costs over 5 years (15 years for foreign research) instead of deducting them immediately.
The One Big Beautiful Bill Act (OBBBA) reverses that change. Starting in 2026, domestic R&D expenses are once again immediately and fully deductible in the year they’re incurred — and the fix is retroactive, providing relief for costs that were forced into amortization during 2022-2025.
This is one of the most impactful OBBBA changes for businesses that invest in innovation, product development, or technology.
Why This Matters: The 2022-2025 Amortization Problem
When Section 174 amortization took effect in 2022, it created a cash flow nightmare for many businesses:
- Before 2022: Spend $100,000 on R&D → deduct $100,000 that year
- 2022-2025: Spend $100,000 on R&D → deduct only $10,000 per year over 5 years (using the midpoint convention, ~$10,000 in year one)
- 2026 onward (OBBBA): Spend $100,000 on R&D → deduct $100,000 that year again
The amortization requirement increased taxable income significantly for R&D-heavy businesses, even though their actual cash spending hadn’t changed. Some businesses saw their tax bills double or triple despite no change in revenue or profitability.
Key OBBBA Provisions for R&D Expenses
1. Immediate Deductibility Restored
Starting with tax years beginning in 2026, all domestic research and experimental expenditures under Section 174 can be fully deducted in the year incurred. This applies to:
- Employee wages for R&D activities
- Materials and supplies used in research
- Contract research costs (domestic only)
- Software development costs
- Prototype and testing expenses
- Patent-related costs
2. Retroactive Relief for Unamortized Costs
The OBBBA provides retroactive treatment for R&D costs that were amortized during 2022-2025. Businesses can deduct any remaining unamortized Section 174 costs — meaning if you had $500,000 in R&D expenses during 2022-2025 that you were forced to amortize, you can deduct the unamortized balance on your 2026 return.
This is a significant one-time deduction for businesses that accumulated amortized R&D costs over the past four years.
3. Foreign R&D Remains on 15-Year Amortization
Important distinction: the OBBBA restores immediate deductibility only for domestic R&D expenses. Research conducted outside the United States still must be amortized over 15 years under Section 174(b). If your business conducts research in multiple countries, you’ll need to separate domestic from foreign R&D costs.
Who Qualifies for the R&D Deduction?
The R&D deduction isn’t just for large tech companies or pharmaceutical firms. Any business that develops or improves products, processes, software, or techniques may qualify. Common industries and activities include:
Technology Companies
- Software development (new features, platforms, apps)
- Cloud infrastructure development
- AI and machine learning model development
- Cybersecurity research
Manufacturing
- New product design and prototyping
- Process improvement and automation
- Material science testing
- Quality improvement initiatives
Small Businesses and Startups
- Developing a new product or service
- Building custom software tools
- Improving existing products based on customer feedback
- Testing new manufacturing methods
Freelancers and Consultants
- Developing proprietary tools or methodologies
- Creating custom software for client delivery
- Building internal automation systems
The key test is whether the activity involves discovering information that is technological in nature and the work involves a process of experimentation. If you’re trying to eliminate uncertainty about a product’s capability, methodology, or design, your expenses likely qualify.
R&D Deduction vs. R&D Tax Credit
Don’t confuse the R&D expense deduction with the R&D tax credit — they’re separate benefits, and you can potentially use both:
| Feature | R&D Expense Deduction (Section 174) | R&D Tax Credit (Section 41) |
|---|---|---|
| What it does | Reduces taxable income | Reduces tax liability dollar-for-dollar |
| How it works | Deduct R&D expenses from revenue | Calculate credit based on qualified research expenses |
| Who benefits | All businesses with R&D expenses | Businesses meeting the 4-part test |
| Complexity | Relatively straightforward | Requires detailed documentation and calculations |
| OBBBA change | Immediate deductibility restored | No change — credit continues as before |
Pro tip: If you claim the R&D tax credit, you must reduce your Section 174 deduction by the amount of the credit (or elect the reduced credit method). Work with your accountant to optimize which combination produces the best result.
How to Track R&D Expenses
Proper tracking is essential to claim the full R&D deduction. The IRS expects you to substantiate your R&D expenses with records that show:
- What the research activity was: Document the project, its goals, and the uncertainty being addressed
- Who performed the work: Track employee time spent on R&D activities
- What was spent: Keep receipts and records for all materials, supplies, and contracted services
- When the work occurred: Date your activities and expenditures
Categories of R&D Expenses to Track
| Expense Category | Examples | Documentation Needed |
|---|---|---|
| Labor | Developer salaries, researcher wages | Time logs, project assignments |
| Materials | Prototyping supplies, testing materials | Receipts, purchase orders |
| Contract Research | Third-party testing, lab services | Invoices, contracts, statements of work |
| Software/Tools | Development tools, cloud computing costs | Subscription invoices, usage records |
| Equipment | Lab equipment, testing devices | Purchase receipts (may also qualify for Section 179) |
Use SparkReceipt’s AI receipt scanner to capture and categorize R&D-related receipts as you incur them. Create a dedicated category or tag for R&D expenses so they’re easy to pull at tax time. The expense report feature can generate a clean summary of all R&D spending for your accountant.
Handling Unamortized Costs from 2022-2025
If your business had R&D expenses during 2022-2025 that were subject to the 5-year amortization rule, here’s what to do:
Step 1: Calculate Your Unamortized Balance
Review your tax returns from 2022 through 2025. For each year’s Section 174 costs, determine how much has been amortized and how much remains unamortized.
Example: You spent $200,000 on R&D in 2023. Using the 5-year midpoint amortization:
- 2023: Deducted $20,000 (10% — half-year convention)
- 2024: Deducted $40,000 (20%)
- 2025: Deducted $40,000 (20%)
- Remaining unamortized: $100,000
Step 2: Deduct the Remaining Balance in 2026
Under the OBBBA’s retroactive provisions, you can deduct the full unamortized balance ($100,000 in this example) on your 2026 tax return. This is in addition to any new R&D expenses you incur in 2026.
Step 3: Work with Your Accountant
The retroactive calculations can be complex, especially if you had R&D expenses in multiple years during 2022-2025. Your accountant can help ensure you’re capturing the full deduction and filing any necessary amended returns or adjustments.
R&D Deduction for Small Businesses
Small businesses often overlook R&D deductions because they assume “research and development” only applies to large corporations. In reality, many everyday small business activities qualify:
- Developing a new app or website feature: If you’re building something new and solving technical challenges, the development costs likely qualify
- Improving a manufacturing process: Testing new methods, materials, or equipment to improve efficiency
- Creating custom software: Building tools for internal use or client projects that involve solving technical uncertainty
- Developing a new recipe or formula: Food, cosmetics, chemical, or material formulations involving experimentation
Combined with the Section 179 deduction (now up to $2.5 million) and 100% bonus depreciation, small businesses can write off equipment purchases AND R&D costs immediately — significantly reducing their 2026 tax burden.

Common R&D Deduction Mistakes
- Not separating domestic from foreign R&D: Only domestic R&D qualifies for immediate deductibility. Foreign research must still be amortized over 15 years.
- Confusing R&D deduction with R&D credit: They’re different benefits with different rules. You can often use both, but coordinate with your accountant.
- Poor documentation: The IRS can disallow R&D deductions if you can’t substantiate the expenses. Keep detailed records of what was done, who did it, and what was spent.
- Forgetting unamortized costs: If you had R&D expenses in 2022-2025, don’t forget to deduct the remaining unamortized balance in 2026.
- Excluding qualifying activities: Many businesses don’t realize their product development, process improvement, or software work qualifies as R&D.

Bottom Line
The restoration of immediate R&D expense deductibility is one of the OBBBA’s most important changes for businesses that invest in innovation. If you’ve been struggling with the 5-year amortization rule since 2022, 2026 brings significant relief — both for new R&D spending and for unamortized costs from prior years.
The key to maximizing this deduction is meticulous expense tracking. Document every R&D-related expense, from material purchases to contractor invoices, and keep records of the research activities themselves. SparkReceipt’s expense tracker can help you categorize and organize R&D expenses throughout the year, so when tax time arrives, you have everything you need.
