Your R&D Spend Is Cheaper Than It Looks — After the Credit
Companies that spend money developing new or improved products, processes, or software can generally claim the federal R&D tax credit under Section 41 of the tax code, using the Alternative Simplified Credit (ASC) method. If this is your first year claiming the credit and you don't have three years of qualified research expense (QRE) history, the ASC rate is about 6% of current-year QREs; once you've built that history, it climbs to about 14% of QREs above 50% of your prior three-year average. For pre-revenue startups with little or no income tax liability, the credit isn't wasted — qualified small businesses can apply up to $500,000 per year against payroll tax instead, turning R&D spend into real cash savings even before the company is profitable.
How It's Calculated
| Step | Item | Detail |
|---|---|---|
| 1 | Choose method | No QRE history ~6% / With QRE history ~14% |
| 2 | Tax credit | QRE spend × selected credit rate |
| 3 | Net cost | QRE spend − tax credit |
This calculator shows a simplified base-rate estimate only. It doesn't account for the incremental QRE base calculation, alternative credit methods, or state R&D credits, which can further change your actual refund. Confirm your exact QRE eligibility and credit amount with a tax professional.
