What Is the R&D Tax Credit?
Short answer
The R&D tax credit is a federal (and often state-level) tax credit that rewards companies for qualified research activities — like developing or improving products, software, or processes — by directly reducing the tax they owe, sometimes even before the company is profitable.

How the R&D tax credit works
Unlike a deduction, which reduces taxable income, a tax credit reduces the tax owed dollar for dollar — which makes the R&D credit one of the most valuable incentives available to growing companies. It’s calculated based on qualified research expenses (QREs): generally wages for employees doing qualifying research, supplies used in that research, and a portion of contract research costs.
To qualify, activities generally need to meet a four-part test: they must be intended to develop or improve a business component (a product, process, software, technique, or formula), be technological in nature, involve a process of experimentation, and aim to eliminate technical uncertainty. Software development, engineering, and product iteration frequently qualify — including work that doesn’t feel like traditional “R&D.”
Who benefits most
- Pre-revenue and early-stage startups. Qualified small businesses can often apply a portion of the federal R&D credit against payroll taxes, generating real cash savings even before the company owes income tax.
- Software and technology companies. Product development work often qualifies even when it doesn’t look like a traditional research lab.
- Companies that have never claimed it. The credit isn’t automatic — it requires documentation and a study to substantiate the claim, which is exactly why many eligible companies leave it unclaimed.
