How Much Is the R&D Tax Credit Worth?
The federal R&D tax credit is typically worth 6% to 14% of your qualified research expenses. The exact amount depends on which calculation method you use and your historical spending patterns.
Credit calculation methods
There are two ways to calculate the credit. You choose one each year on Form 6765:
Regular Research Credit — IRC §41(a)
20% of current-year QREs exceeding a base amount. The base amount uses your historical ratio of research expenses to gross receipts. For businesses claiming for the first time (no base period data), the minimum base is 50% of current-year QREs, yielding an effective rate of about 10% of QREs.
Alternative Simplified Credit (ASC) — IRC §41(c)(5)
14% of current-year QREs exceeding 50% of your average QREs over the prior three years. For businesses with no prior-year QREs, the credit is 6% of current-year QREs.
Examples by business size
| Annual qualifying expenses | Estimated credit (Regular, first-time) | Estimated credit (ASC, no prior QREs) |
|---|---|---|
| $200,000 | ~$20,000 | ~$12,000 |
| $500,000 | ~$50,000 | ~$30,000 |
| $1,000,000 | ~$100,000 | ~$60,000 |
| $2,000,000 | ~$200,000 | ~$120,000 |
These are simplified estimates for first-time claimants. Your actual credit depends on your specific base amount calculation. Use the free calculator for a personalized estimate.
What makes the credit larger?
- More qualifying employees: The more employees performing R&D, the higher your QREs
- Higher wages: Employee compensation is typically the largest QRE category
- Contractor spending: Contract research payments add to QREs (at 65%)
- Multiple years: If you have never claimed, you may be able to amend prior years and recover credits going back three years
Credit vs. deduction
The R&D credit is a dollar-for-dollar reduction in tax, not a deduction. A $50,000 credit saves you $50,000 in taxes. A $50,000 deduction saves you $50,000 times your tax rate (for example, $10,500 at a 21% corporate rate). Credits are significantly more valuable.
Payroll tax offset for startups
Qualified small businesses can apply up to $500,000 of the credit against payroll taxes each year. See Startup Payroll Tax Credit for eligibility.
