The IRS has released its 2026–2027 per diem rates for certain business travel expenses, effective Oct. 1, 2026. Under the high-low substantiation method, the rate for lodging, meals and incidental expenses for travel to high-cost localities within the continental United States (CONUS) rises to $329 per day, from $319. The rate for other CONUS localities rises to $230, from $225. The portion attributable to meals remains $86 for high-cost areas and $74 for other areas. The incidental-expenses-only rate remains $5. Employers can pay more than the IRS per diem rates, but excess amounts generally must be substantiated or treated as taxable wages.
