Effective July 1, the Internal Revenue Service (IRS) has revised the standard mileage reimbursement rate to $0.76 per mile. Please note this is an increase from the $0.725 IRS rate during the first half of 2026. All state agencies may use the new $0.76 rate for travel incurred on and after July 1.
The Trip Optimizer law is still in place for determining the lowest cost of transportation for travel on state business. The new $0.76 rate is now used for the mileage calculation and for the OMES mileage reimbursement amount referenced in paragraphs E and F of 74 O.S. § 85.45l.
