R&D Tax Credit HubQualifying Activities

You Don't Need a Lab Coat.

The most common reason businesses miss out on the R&D Tax Credit is a misconception about what "R&D" means. The IRS definition is broad — and if your company solves technical problems, you're likely doing qualifying work right now.

What the IRS Actually Means by "R&D"

When most people hear "R&D," they picture pharmaceutical companies running clinical trials or aerospace engineers testing rocket engines. That's not the IRS definition.

The IRS defines qualifying research as any activity that attempts to develop or improve a product, process, technique, formula, or software — where the outcome was technically uncertain when you started, and where you used a systematic process (testing, iteration, evaluation) to resolve that uncertainty.

That covers a lot of ground. A manufacturer designing a custom fixture. A software company building a new integration. A construction firm testing a new structural approach. A food company reformulating a product. All of these are qualifying R&D activities.

Activities That Typically Qualify

This is not an exhaustive list — qualifying activities vary by industry and business. But these are the most common types of work that meet the IRS criteria:

Developing or improving products, processes, or software
Designing prototypes or pilot models
Testing and evaluating new materials or techniques
Writing new code or improving existing software
Solving technical problems through experimentation
Improving manufacturing efficiency or yield
Developing new formulations or compounds
Designing and testing custom tools or equipment
Iterating on designs based on test results
Evaluating alternative approaches to a technical problem
Developing new algorithms or data processing methods
Building or improving APIs and system integrations
Designing innovative structural or mechanical systems
Testing new crop strains or agricultural techniques
Developing medical devices or diagnostic tools

Activities That Don't Qualify

Not all technical work qualifies. The IRS excludes certain activities even when they require skilled labor:

Routine maintenance and repairs

No technical uncertainty — the process is known.

Quality control testing of finished products

Testing after production, not during development.

Market research and consumer surveys

Not technological in nature.

Style or cosmetic changes only

Must involve functional improvement.

Adapting existing products for a specific customer

Unless it involves genuine technical uncertainty.

Research funded by another party

The credit goes to whoever bears the financial risk.

Improvement Counts — Not Just Invention

One of the most important things to understand: you don't need to be creating something new to the world. The IRS explicitly includes activities that improve existing products, processes, or software.

If you redesigned a component to reduce failure rates, improved a manufacturing process to cut waste, or refactored software to improve performance — those are qualifying activities. The key is that the outcome was technically uncertain when you started, and you used a systematic process to figure it out.
