Can a Project Involving Known Technology Still Be R&D?

A project involving known technology may constitute qualified research if it involves a technical uncertainty and a process of experimentation. The use of known technology does not disqualify the work, but the uncertainty must be genuine.

A common question is whether a project involving known technology can still qualify as R&D for the federal R&D tax credit. The short answer is that a project involving known technology may constitute qualified research if it involves a technical uncertainty and a process of experimentation. The use of known technology does not disqualify the work, but the uncertainty must be genuine. 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.

Known Technology May Be Used

The Treasury Regulations provide that a taxpayer may employ existing technologies and may rely on existing principles of the hard sciences, engineering, or computer science. The technological-in-nature element does not require inventing new scientific principles — only that the process of inquiry fundamentally relies on them. For more, see our page on technological in nature.

The Uncertainty Must Be Genuine

While known technology may be used, the work must involve a genuine technical uncertainty about the capability, method, or appropriate design of a business component. If the information available to the taxpayer already establishes the capability, method, or design, there may be no qualifying uncertainty — even if known technology is being applied. For more, see our page on elimination of uncertainty.

The Distinction: Applying Known Technology vs. Resolving Uncertainty

The distinction is between applying known technology to a known problem and resolving a technical uncertainty:

  • Applying known technology — using known technology to solve a known problem with a known approach. There is no technical uncertainty. This is application, not research.
  • Resolving uncertainty — using known technology to resolve a technical uncertainty about whether a new or improved business component can achieve a required performance. This may warrant review.

The key question is whether there is a genuine technical uncertainty about the capability, method, or design of the business component, not whether the technology is known.

Hypothetical Example

Consider a company that uses known engineering principles to develop a new product and is uncertain whether the product can achieve the required performance. The company evaluates alternative designs, tests each, and systematically varies the approach to resolve the uncertainty. This work may warrant review as qualified research, even though the engineering principles are known.

By contrast, if the company applies known technology to a known problem with a known approach, that is application, not research.

These examples are illustrative only and do not state whether any particular activity qualifies.

Key Takeaway

A project involving known technology may constitute qualified research if it involves a technical uncertainty and a process of experimentation. The use of known technology does not disqualify the work, but the uncertainty must be genuine. Because the analysis is fact-specific, professional review is appropriate before claiming the credit.
