100% deduction for trucker per diem in COVID-19 Pandemic Relief Package confirmed by the IRS in Notice 2021-63 (12/6/2021)

[Update: The temporary 100% deduction for per diem expired on December 31, 2022]

Full Deduction for Business Meals

Congress used a single line on page 4871 of the Consolidated Appropriations Act, 2021 (CAA) to allow the full deduction for per diem. Section 210 of the act temporarily raised the allowance of business meals (for food or beverages provided by a restaurant) under IRC § 274(n) to 100% from 50% for tax years 2021 and 2022.

The IRS issued Notice 2021-25 on April 8, 2021 (updated by Notice 2021-63 on December 6, 2021) that explains when the temporary 100-percent deduction applies and when the 50-percent limitation continues to apply for purposes of § 274 of the Internal Revenue Code (Code), as amended by § 210 of the Taxpayer Certainty and Disaster Tax Relief Act of 2020 (Act), enacted as Division EE of the Consolidated Appropriations Act, 2021, Pub. L. No. 116- 260, 134 Stat. 1182 (December 27, 2020)

The IRS previously allowed motor carriers and self-employed truckers using the Special Transportation Industry per diem to deduct business meals at 80% under 274(n)(3). Unfortunately, Congress omitted any commentary on the interplay of 274(n)(1) and (3) in the CAA. On April 9, 2021, I called the Office of Associate Chief Counsel (Income Tax & Accounting) and obtained confirmation the temporary 100-percent deduction for business meal expenses applied to the transportation industry as well. The Associate Chief Counsel's opinion was affirmed by issuance of IRS Notice 2021-63 on December 6, 2021.

"Absolutely yes, we tried to allow as many taxpayers to use it as possible"
