IR-2021-225, November 16, 2021 WASHINGTON — The Internal Revenue Service today issued Notice 2021-63 PDF to make clear how the temporary 100% business deduction for food or beverages from restaurants applies to taxpayers properly applying the rules of Revenue Procedure 2019-48 PDF for using per diem rates. Previously, the IRS issued Notice 2021-25 PDF providing guidance under the Taxpayer Certainty and Disaster Relief Act of 2020, which added a temporary exception to the 50% limit on the amount that businesses may deduct for food or beverages. The temporary exception allows a 100% deduction for food or beverages from restaurants, as long as the expense is paid or incurred in 2021 or 2022. For a taxpayer properly applying the rules of Revenue Procedure 2019-48, Notice 2021-63 provides a special rule that allows the taxpayer to treat the full meal portion of a per diem rate or allowance as being attributable to food or beverages from a restaurant beginning January 1, 2021, through December 31, 2022. Taxpayers should refer to section 6.05 of Revenue Procedure 2019-48 to determine the meal portion of a per diem rate or allowance paid or incurred.
