Qualified Research Expenses

How Do Reimbursed Research Costs Affect the R&D Tax Credit?

Reimbursed research costs may be excluded as funded research if the reimbursement means the taxpayer does not bear the economic risk of failure.

A common question is how reimbursed research costs affect the R&D tax credit under Section 41. The short answer is that reimbursed research costs may be excluded as funded research if the reimbursement means the taxpayer does not bear the economic risk of failure. 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 expenses.

Key Considerations

The analysis depends on the specific facts and circumstances. Under the four-part test, qualified research must be for a permitted purpose, be technological in nature, be intended to eliminate uncertainty, and be conducted through a process of experimentation.

Common scenarios that may warrant review include:

  • New development — evaluating alternative approaches to resolve uncertainty about whether a new approach can achieve the required performance.
  • New arrangement — testing alternative approaches to resolve uncertainty about whether a new arrangement can achieve the required outcome.
  • New application — evaluating alternative approaches to resolve uncertainty about whether an existing approach can perform in a new context.
  • New requirement — testing alternative approaches to resolve uncertainty about whether a new requirement can be met.

Funded-Research Considerations

The funded-research exclusion under Section 41(d)(4)(H) may apply. The analysis examines whether the taxpayer bears the economic risk of failure and retains substantial rights in the research results. The specific contract terms control, not the label.

Hypothetical Example

Consider a company that is evaluating a new approach and is uncertain whether any available method can achieve the required outcome. The company evaluates alternative approaches, tests each, and systematically varies the approach to resolve the uncertainty. This may warrant review as qualified research.

By contrast, if the same company performs routine work using established methods, that is routine work, not research.

This example is illustrative only and does not state that the activity definitely qualifies.

Documentation That May Help

Records that can help support this work include records identifying the uncertainty and alternative approaches, test results, and records of how results informed decisions. For more, see our page on R&D tax credit documentation.

Key Takeaway

Reimbursed research costs may be excluded as funded research if the reimbursement means the taxpayer does not bear the economic risk of failure. Because the analysis is fact-specific, professional review is appropriate before claiming the credit.
