Existing Treasury Regulations require that for a claim for refund to be valid, it must set forth sufficient facts to apprise the IRS of the basis of the claim. The IRS has set forth the items of information that taxpayers are required to include for a claim for refund that includes an IRC Section 41 research credit to be considered valid. Applying advice provided in a recent Chief Counsel legal memorandum, the IRS will be improving tax administration with clearer directions for eligible taxpayers whose claim for refund includes an IRC Section 41 research credit while reducing the number of disputes over such claims. Effective tax administration entails ensuring taxpayers understand what is required to support an IRC Section 41 research credit claim for refund. Each year, the IRS receives thousands of IRC Section 41 research credit claims for refund in the hundreds of millions of dollars from corporations, businesses, and individual taxpayers. IRC Section 41 research credit claims for refund are currently examined in a substantial number of cases and consume significant resources for both the IRS and taxpayers. The Chief Counsel legal memorandum released on October 15, 2021, was the result of ongoing efforts to manage IRC Section 41 research credit issues and resources in the most effective and efficient manner.
