The IRS announced per diem rates for lodging, meals, and incidental expenses within the continental U.S. (CONUS) and outside CONUS for the government’s fiscal year 2023, which began on October 1, 2022. The CONUS rate for FY 2023 is $297 per day ($1 more than in FY 2022) to areas designated as high-cost localities and $202 per day for all other areas within CONUS ($2 more than in FY 2022). Employers that use the IRS’s per diem rates to reimburse employees for business travel may continue to use the rates applicable for the first 9 months of 2022 or change to the new rates for the last quarter of 2022. The per diem rates substantiate cost; all other substantiation (recordkeeping) rules found in IRS Publication 463 apply. #IdeaoftheDay
