IRS Tightens Documentation Requirements for Refund Claims

May 17, 2022

Research credits

In recent guidance, the IRS has imposed strict new documentation requirements on businesses that file refund claims for federal research credits. These tax breaks are often referred to as “research and development,” “R&D” or “research and experimentation” credits. 


Currently, businesses may claim the research credit on an originally filed return or an amended return. The new requirements apply to the latter, although it’s possible that the IRS will attempt to enhance the documentation requirements for originally filed returns down the road.

Overview of the credit

While the research credit and related regulations are complex, in a nutshell, they allow a business to claim a credit for a portion of its increased expenses attributable to qualified research activities (QRAs). Generally, QRAs are activities that:

  • Are incurred in connection with the taxpayer’s trade or business,
  • Strive to discover information that’s technological in nature, 
  • Relate to a new or improved business component, such as a product, process, computer software, technique, formula or invention, and
  • Are part of a process of experimentation.


Historically, a business claiming the research credit — whether on an originally filed return or an amended return — didn’t need to include specific documentation with its filing. Rather, the business was required to “retain records in sufficiently usable form and detail to substantiate that the expenditures claimed are eligible for the credit.”

New requirements

The new guidance is based on the specificity requirement in the IRS regulations. Under this requirement, a taxpayer claiming a refund must “set forth in detail each ground upon which a credit or refund is claimed and facts sufficient to apprise the Commissioner of the exact basis thereof.” Accordingly, for a research credit refund claim to be valid, a taxpayer must, at a minimum, follow these three steps:

  1. Identify all business components to which its research credit claim relates for that year.
  2. For each business component, identify all research activities performed, all individuals who performed each research activity and all the information each individual sought to discover.
  3. Provide the total qualified employee wage expenses, total qualified supply expenses and total qualified contract research expenses for the claim year (for example, using Form 6765, “Credit for Increasing Research Activities”).


This is a significant departure from previous guidance. Previously, businesses had to retain records to substantiate the research credit, but they weren’t required to include such documentation with their amended returns. Not only does the new guidance place additional burdens on businesses filing refund claims for the research credit, but it also increases the risk that the credit will be denied. 


Suppose, for example, that a business files a refund claim shortly before the statute of limitations expires (generally, three years after the original filing or two years after the tax was paid, whichever is later). If the IRS rejects the claim for failure to meet the new documentation requirements, the business will lose the opportunity to refile its claim to supply the missing information.

Temporary relief

The new requirements apply to refund claims postmarked after January 10, 2022. During a one-year transition period that runs through January 9, 2023, the guidance provides some relief for taxpayers that file deficient claims. 


These taxpayers will receive a letter from the IRS detailing the missing information and providing them with 45 days to “perfect” the filing. So long as the initial refund claim was filed on a timely basis, a claim that’s perfected within this 45-day period will also be considered timely, even if the statute of limitations has expired.

Get your papers in order

If you plan to file an amended return to claim the research credit, familiarize yourself with the new documentation requirements and be sure you have all the information to include with your return. Once the transition period ends, there will be no do-overs. Contact your tax advisor for assistance.

Sidebar: What’s happening with research expense deductions?

Traditionally, there have been two distinct tax benefits for businesses that conduct research: the research credit and the deduction for research expenses. Previously, businesses had the option of deducting these expenses immediately in the year they’re paid or incurred. But under the Tax Cuts and Jobs Act (TCJA), starting this year, most research expenditures must be capitalized and amortized over at least five years (15 years for research conducted outside the United States).


This requirement will affect not only the deductibility of research expenses but also the value of the research credit. Be aware, however, that legislation pending in Congress would delay the requirement until 2026. Stay tuned.

The Corporate Transparency Act (CTA) which took effect on January 1, 2024 required "reporting companies" in the United States to disclose information about their beneficial owners to the Treasury Department's Financial Crimes Enforcement Network (FinCEN). In May 2024, a lawsuit was filed claiming that Congress exceeded its authority under the Constitution in passing the CTA. Background: December 3, 2024 in the Texas Top Cop Shop, Inc., et al. v. Merrick Garland, Attorney General of the United States, et al., Judge Amos Mazzant of the United States District Court (Eastern District of Texas/Sherman Division) issued a preliminary nationwide injunction barring the enforcement of the Corporate Transparency Act (CTA). December 23, 2024 the Nationwide Injunction is lifted and filing deadlines are reinstated. Financial Crimes Enforcement Network of the U.S. Department of Treasury (FinCEN) may again enforce the CTA. FinCEN has not extended any filing deadlines. Therefore, all reporting companies should file immediately any beneficial ownership information reports (BOIRs) that were already due, and reporting companies formed prior to 2024 should file their BOIRs by January 13, 2025 (extended from January 1, 2025). December 27, 2024 the federal appeals court on Thursday reinstated a nationwide injuction halting enforcement of beneficial ownership information (BOI) reporting requirements, reversing an order the same court issued earlier this week. FinCEN issued an updated alert on its BOI information page , saying that companies can voluntarily submit BOI reports. February 7, 2025 FinCEN will consider changes to the BOI reporting requirements if a court grants the government's request for a stay of a nationwide injunction in a Texas case, according to a motion filed Wednesday, February 5th. If the stay is granted, FinCEN will extend BOI filing deadlines for 30 days, the government said in its filing in Samantha Smith and Robert Means v. U.S. Department of the Treasury, No. 6:24-CV-336 (E.D. Texas 1/7/25). BOI reporting is currently voluntary, pending further legal developments. Businesses and stakeholders should stay alert for additional updates as the situation evolves. Current Status: February 18, 2025 A federal court lifted the last remaining nationwide injunction stopping BOI reporting requirements. FinCEN which enforces BOI requirements under the CTA said it would extend filing deadline for initial, updated, and/or corrected BOI reports to March 21. However, reporting companies that were previously given a deadline later than March 21 may file their initial BOI report by that later deadline. Resources for consideration: March 21 BOI reporting deadline set; further delay possible BOI Injunction Lifted FinCEN BOI Center
