What Is the R&D Tax Credit?
Learn what the R&D tax credit is, how it works, what qualifies as research, and how businesses use it to reduce income or payroll taxes.

The Research and Development (R&D) Tax Credit, formally known as the Credit for Increasing Research Activities, is a federal tax incentive designed to reward companies for investing in innovation.
If your business develops or improves products, software, processes, formulas, or technologies, you may qualify for a dollar-for-dollar reduction of federal taxes. The credit is calculated on IRS Form 6765 and filed with your annual tax return.
Despite the name, the R&D credit is not limited to labs, scientists, or white coats. Many companies claim it every year without realizing their work qualifies.
How the R&D Credit Works
The R&D tax credit reduces your tax liability based on Qualified Research Expenses (QREs) incurred during the year.
For profitable companies, the credit typically offsets income taxes owed.
For early-stage companies, Congress created a way to access the credit even before profitability.
Payroll Tax Offset for Small Businesses
If your business:
Is less than five years old, and
Has under $5 million in gross receipts,
you may be able to use the R&D credit to offset payroll taxes instead of income taxes. This provides real cash benefit today, not later.
Unused R&D credits can also be carried forward for up to 20 years and applied when taxes are due in the future.
What Counts as R&D for Tax Purposes?
The tax definition of research is much broader than most people expect.
For R&D credit purposes, research generally means:
Using a trial-and-error process
To eliminate technical uncertainty
In the development or improvement of a product, process, software, formula, or invention
The research must be conducted within the United States, including Puerto Rico and Guam.
If that sounds complex, it is. It took the federal government more than 20 years to finalize the rules.
The Four-Part R&D Test
To qualify, activities must meet all four parts of the R&D test under the Internal Revenue Code.
1. Uncertainty Test
The activity must seek to eliminate uncertainty related to:
Capability
Method
Appropriate design
The goal must be to discover information that resolves that uncertainty.
2. Technological in Nature Test
The research must rely on principles of:
Engineering
Computer science
Physical sciences
Biological sciences
3. New or Improved Business Component Test
The research must relate to developing or improving a:
Product
Process
Software
Technique
Formula
Invention
4. Process of Experimentation Test
At least 80 percent of the activities must involve a process of experimentation, meaning systematic trial and error, modeling, simulation, or testing alternatives.
What Costs Qualify for the R&D Credit?
Qualified Research Expenses generally fall into four categories.
Wages paid to employees for time spent on:
Direct research activities
Supervising research
Supporting research
Note: Only the portion of time related to qualified research is included.
Supplies Costs used in research, including:
Raw materials
Utilities
Prototype materials
Pilot models used for testing
Contract Research - Generally, 65 percent of payments to third parties for qualified research performed on your behalf.
Computer Usage - Amounts paid for the right to use computers in the conduct of qualified research.
How Much Is the R&D Credit Worth?
The value of the credit depends on your facts, history, and calculation method. There are two primary federal calculation methods.
Method 1: Regular Credit Method
Gross credit equals 20 percent of qualified expenses above a base amount
For many companies, this equates to roughly 10 percent of QREs
Net benefit is often around 8 percent, depending on tax rate
Method 2: Alternative Simplified Credit (ASC)
Gross credit equals 14 percent of current year QREs minus 50 percent of the prior three-year average
If spending is consistent, this typically equals about 7 percent
First-year filers often receive around 6 percent
State R&D Credits
Many states offer their own R&D credits. Rules and rates vary widely.
States like California and Utah offer credits comparable to the federal program
Other states offer smaller incentives
When federal and state credits are combined, total net benefits often average around 12 percent of qualified research costs.
Why the R&D Credit Is Often Missed
Most missed R&D credits are not caused by a lack of innovation. They are caused by:
Incomplete analysis
Overreliance on prior-year assumptions
Manual, spreadsheet-based studies
Misinterpretation of the qualification rules
Understanding the rules is the first step. Applying them correctly is where most providers fall short.
Not Sure If You Qualify? Let’s Find Out.
Most companies that qualify never claim the full credit. Not because they lack innovation, but because the analysis stops short.
