A common question is whether comparing or testing existing products counts as research and development for the federal R&D tax credit under Section 41. This is an important distinction page. The short answer is that the answer depends heavily on the purpose and nature of the testing. Merely testing commercially available options to select one is generally a weak fact pattern. Using testing to identify technical failures, modify specifications or designs, evaluate alternatives, and develop an improved business component is a potentially stronger fact pattern. This page explains the framework in general terms. It is educational and is not individualized advice. For the foundational framework, see our page on qualified research.
The Weak Fact Pattern: Selecting Among Options
The weak fact pattern is a company that tests or compares commercially available products merely to select one for purchase or use. For example, a company that tests three commercially available adhesives to determine which performs best, and then purchases the best-performing one, is generally performing a purchasing evaluation, not qualified research. There is no process of experimentation directed at developing or improving a business component; the company is selecting among existing products. The permitted-purpose element — which requires that the work be directed at developing or improving a business component — is generally not satisfied, because the company is not developing or improving anything; it is selecting.
This is true even if the testing is thorough, uses sophisticated equipment, or produces detailed results. The question is not whether the testing is rigorous, but whether it is part of a process of experimentation directed at developing or improving a business component.
The Stronger Fact Pattern: Using Testing to Develop an Improved Component
The stronger fact pattern is a company that uses testing of existing products to identify technical failures, understand why they fail, modify specifications or designs, evaluate alternatives, and develop an improved business component. In this scenario, the testing is part of a process of experimentation — the company is not merely selecting; it is using the test results to inform the development of something new or improved. The four-part test is applied to the development activity, and the testing is part of the evaluative process.
For example, a company that tests competing products to identify their failure modes, uses the failure analysis to design an improved product, and then tests its own improved design against the failure modes may be conducting qualified research. The testing of existing products is part of the process of experimentation directed at developing an improved business component.
Treasury Regulation Examples
The Treasury Regulations (§1.41-4) describe a process of experimentation as an evaluative process designed to evaluate alternatives to resolve a technical uncertainty. The regulations do not categorically exclude testing of existing products; the question is whether the testing is part of such an evaluative process. Where the testing is merely evaluative comparison for selection, it generally does not fit the framework. Where the testing is part of a process of identifying uncertainties, evaluating alternatives, and developing improvements, it may.
Hypothetical Example
Consider a company that is developing a new type of industrial valve and wants to understand why competing valves fail prematurely in a specific application. The company purchases several competing valves, tests them to failure in simulated operating conditions, analyzes the failure modes, uses the analysis to design an improved valve, and then tests its own improved design. The testing of the competing products — used to identify failure modes and inform the improved design — is part of the process of experimentation directed at developing an improved valve. The wages of the engineers and the materials consumed in the testing may warrant review as qualified research expenses, provided the other elements are met.
By contrast, if the same company simply tests three competing valves to determine which lasts the longest and then purchases that valve for its own use, that is a purchasing evaluation, not qualified research.
This example is illustrative only and does not state that the activity definitely qualifies.
Documentation That May Help
Records that can help support product-comparison testing claims include test plans describing the purpose (development vs. selection), records of failure analysis, records of how test results informed design changes, records of alternatives evaluated, and records connecting the work to the specific business component being developed or improved. For more, see our page on R&D tax credit documentation.
Key Takeaway
Comparing or testing existing products is a weak fact pattern for the R&D tax credit when the purpose is merely to select among commercially available options. A stronger fact pattern exists when testing is used to identify technical failures, modify specifications or designs, evaluate alternatives, and develop an improved business component. Because the distinction turns on the purpose and nature of the testing, professional review is appropriate before claiming the credit.
