The Research and Experimentation (R&E) Credit, also known as the Research and Development (R&D) Credit, is submitted on federal form 6765. It compiles the amounts of Qualified Research Expenses (QREs) and computes the total credit for the tax year. Taxpayers seeking to amend a prior year’s return to claim the R&D tax credit are now required to provide the IRS with additional documentation at the time of filing rather than waiting for IRS review.
Historically, the IRS only required that the company maintain data to support the claim upon examination (audit) for credits claimed on either a timely filed or amended return. The IRS has stated that reviewing claims is consuming substantial resources and released a memo in October 2021 with new guidelines. The new guidance, which does not currently apply to timely filed returns, is intended to diminish this burden on taxpayers and the agency. However, the effect is actually the opposite for taxpayers who now bear an additional reporting burden.
Information You Need To Provide
In addition to the traditional filing of the 6765 and maintaining documentation, taxpayers will need to provide the following when filing the claim for refund:
- Identify all the business components to which the Section 41 research credit claim relates for that year,
- Identify all research activities performed for each business component, and
- Provide the total qualified employee wage expenses, total qualified supply expenses, and total qualified contract research expenses for the claim year. Taxpayers may use Form 6765, Credit for Increasing Research Activities for this purpose.
This supporting information must be provided using a written statement, not just submitting a stack of documents. The IRS is also allowing the new Form 6765, Credit for Increasing Research Activities to be used for companies provide this information. Claims that do not comply with the new guidance will be rejected.
What if a Claim Does Not Provide Sufficient Information?
The IRS has again, as of October 2025, extended the research credit claim transition period to January 10, 2027. This gives taxpayers 45 days to perfect a research credit claim for refund prior to the IRS’s final determination on the claim.
Next Steps for Taxpayers
The landscape for claims for R&D Credit refunds has changed dramatically in the last several months. This enhanced documentation requirement may add significant administrative efforts for taxpayers and preparers. Even though the memorandum was released with no period for public commentary, practitioners and taxpayers will likely see additional publications from the IRS in the upcoming months and years.
