Yes. You do not need an R&D department to claim the federal R&D tax credit. The credit under IRC Section 41 is based on the work your people do, not on job titles or how your company is organized.
Key takeaways
- The R&D credit follows the activity, not the department.
- Work qualifies when it passes the IRS four-part test.
- Engineers, developers, and technicians in normal roles often do qualifying work.
- Wages, supplies, and outside research costs can all count.
- Records your team already keeps are usually the best documentation.
How does the IRS decide what counts as R&D?
The IRS looks at each product, process, software, technique, formula, or invention you worked on and asks whether the work behind it meets the four-part test. Nothing in the law requires a research budget, a lab, or a team labeled R&D.
What is the four-part test for the R&D tax credit?
The four-part test is how the IRS decides whether work is qualified research. All four parts must be met:
- Permitted purpose. The goal is a new or improved function, performance, reliability, or quality.
- Technological in nature. The work relies on engineering, physical or biological science, or computer science.
- Elimination of uncertainty. At the start, the team did not know how to achieve the result or which design would work.
- Process of experimentation. The team tested alternatives through modeling, prototyping, simulation, or trial and error.
The work does not have to succeed. Failed prototypes and abandoned designs can qualify.
Which employees do qualifying R&D work?
The people solving technical problems as part of their regular jobs. Common examples include:
- Manufacturing: manufacturing, process, and controls engineers, CNC programmers, and tooling specialists. See R&D credits for manufacturers.
- Software: developers and architects building new features or solving performance problems. See R&D credits for SaaS companies.
- Engineering and design firms: engineers and designers working through new system designs. See R&D credits for architecture and MEP firms.
People who directly supervise or directly support the research, such as a technician who builds and runs test samples, can qualify too.
What expenses count toward the R&D tax credit?
Three categories of spending count as qualified research expenses:
- Wages for time spent performing, supervising, or supporting qualified research.
- Supplies used up in the research, such as prototype materials and test samples.
- Contract research, generally 65 percent of what you pay outside firms to do qualified research for you.
For companies without an R&D department, wages are usually the largest category.
What work does not qualify for the R&D tax credit?
Common exclusions include:
- Routine production after a product is finished
- Customizing an existing product for one customer without new technical uncertainty
- Copying an existing product
- Routine quality control testing
- Market research and surveys
- Research paid for by a customer when you carry no risk of failure
- Research done outside the United States
How do you document R&D without an R&D department?
Use the records your team already creates. Design files and revision history, engineering change orders, test reports, project tickets, and meeting notes show what was uncertain and how the team tested its way to an answer. Records made while the work happened carry much more weight than summaries written later.
To get started:
- List last year's projects where the team did not know at the start how to get the result.
- Note who worked on each one and roughly how much of their time it took.
- Gather the records that show what was tried and what changed.
If your team solves technical problems as part of everyday work, the credit may be worth more than you expect. Our R&D tax credit overview explains how a study works, and our industry guides show what qualifying work looks like in your field.
Frequently asked questions
No. The IRS looks at what the work involved, not what it was called. Your records should show the technical uncertainty the team faced and how it tested its way to an answer.
Yes. The credit rewards the process of experimentation, not the outcome. A scrapped design or an abandoned process change can qualify if the work met all four parts of the test.
Often, yes. A qualified small business, generally one with less than $5,000,000 in gross receipts and no gross receipts more than five years back, can apply up to $500,000 of the credit each year against its payroll taxes.
Often, yes. Open tax years can generally be amended, usually within three years of filing the original return. Refund claims must include specific detail about the research and the expenses claimed.
