Enter your R&D wages, contractor costs and supplies below to get an instant estimate using the Alternative Simplified Credit method - the calculation method used by most small businesses.
ASC method · 2026 tax year · Federal only
The ASC method needs your average QREs from the past 3 years. If this is your first year or you have no prior R&D history, leave these blank and we'll use the startup rate of 6%.
Profitable business applying credit against income tax.
Estimate only - not tax advice. Actual credit depends on your full qualified research expenses, tax situation and IRS guidelines.
The number above is a starting point, not a guarantee. But it gives you a real sense of the scale before you invest time talking to a specialist. Most businesses are surprised how large the estimate is, because the credit is calculated on total R&D spend, not just profit.
There are two IRS-approved methods. This calculator uses the Alternative Simplified Credit (ASC) - the method chosen by the vast majority of small and mid-size businesses because it's simpler and doesn't require historical gross receipts data going back decades.
The ASC gives you 14% of the QREs that exceed 50% of your average QREs over the prior 3 years. If you have no prior-year QREs (first-year claimant or startup), the rate is a flat 6% of all current-year QREs.
QRE stands for Qualified Research Expenses - the total of your qualifying wages, 65% of contractor costs and qualifying supplies. That's what the calculator builds up from your inputs.
The other method gives 20% of QREs above a base amount tied to your historical R&D intensity (QREs as a % of gross receipts over a fixed base period). For companies that spent very little on R&D in the past but are spending heavily now, this can produce a larger credit. A specialist will model both and use whichever is higher.
| Expense Type | Qualifies? | How Much Counts |
|---|---|---|
| Employee wages (R&D time only) | Yes | 100% of qualifying time |
| Contractor / CRO payments | Yes | 65% of amount paid |
| Lab supplies & reagents | Yes | 100% if consumed in research |
| Cloud computing (R&D use) | Yes | 100% of qualifying usage |
| Prototype materials | Yes | 100% if consumed in testing |
| Capital equipment | No | Depreciated separately |
| Grant-funded research | No | Must bear financial risk |
| Foreign research | No | US-based only |
| Management / admin time | No | Must be direct research activity |
If your business is under 5 years old with under $5M in annual gross receipts, you don't need to be profitable to benefit. You can apply up to $500,000 per year of your R&D credit directly against employer payroll taxes - real cash out of your quarterly 941 payments.
This is why the calculator separates established businesses from startups. For a startup, even a $40,000 credit is $40,000 off your next payroll tax bill - actual money back in your operating account.
The number this calculator gives you is based on the expenses you know about and enter. A specialist typically finds more because:
The average first-year recovery for businesses working with a specialist is typically 30–50% higher than owner-estimated figures.
The number from the calculator is a conversation starter, not a filing number. Here's what to do with it:
Specialist firms like TaxTaker and more work on contingency - they take a percentage of what they recover, so there's no upfront cost and no risk if they find nothing. The free review takes about 15 minutes.
Yes. Form 6765 is the IRS form for the R&D credit and you or your CPA can complete it. The risk is underclaiming (missing qualifying expenses), miscalculating the base amount or creating audit exposure with insufficient documentation. For credits over $25,000 a specialist study is generally worth it.
No, these are two different tax benefits. The Section 41 credit (what this calculator estimates) reduces your tax dollar-for-dollar. The Section 174 deduction reduces your taxable income. They work differently, have different qualifying rules and can sometimes be used together. See our R&D credit vs deduction guide for the full breakdown.
This calculator covers federal only. 36 states offer their own R&D credit ranging from 5% to 24% of QREs. California, Massachusetts, New York, Texas, Maryland and New Jersey all have meaningful state credits that stack on top of the federal amount. Your total combined credit could be significantly higher.
Double-check that you're entering only the portion of wages spent on qualifying R&D - not total payroll. Engineers who spend 40% of their time on development contribute 40% of their wages to your QRE, not 100%.
Yes, you can amend tax returns for the prior 3 years. If you've been doing qualifying R&D work for several years without claiming, your first recovery often includes multiple years stacked together.
