The R&D Tax Credit: Is Your Business Eligible?

The R&D tax credit isn't just for tech giants. Many small businesses qualify for this significant credit. Here's what counts as qualifying research.

Research & Development (R&D) Tax Credit

What Is the R&D Tax Credit?

Section 41 allows businesses to claim a credit for qualified research expenses. It can be a substantial, often overlooked credit.

The Four-Part Test for Qualified Research

  1. Technological uncertainty: There's uncertainty about how to develop or improve the product/process
  2. Process of experimentation: You evaluate alternatives through trial and error
  3. Technological in nature: Activities rely on hard sciences (engineering, physics, chemistry, biology, computer science)
  4. Qualified purpose: Developing a new or improved product, process, formula, invention, or software

What Qualifies

  • Developing new products or prototypes
  • Designing and testing new manufacturing processes
  • Developing or improving software (if it meets the 4-part test)
  • Engineering and architectural design work
  • Environmental testing related to development

What Doesn't Qualify

  • Research after commercial production begins
  • Adaptation of existing products to a customer's needs
  • Duplication of existing products
  • Social science research
  • Management studies or surveys
  • Reverse engineering

Credit Amount

  • Regular method: 20% of expenses above a base amount
  • Alternative Simplified Credit (ASC): 14% of expenses exceeding 50% of average prior 3 years

Payroll Tax Offset for Startups

Qualified small businesses (under $5M gross receipts, under 5 years old) can offset up to $500,000/year in payroll taxes with the R&D credit.


Innovation happening in your business? You may qualify for R&D credits you've never claimed.
