The IRS announced an increase in the mileage reimbursement rate effective Jan. 1, 2025, to $0.70 per mile. This is an increase from the $0.67 IRS rate for 2024. (Refer to Internal Revenue Notice 2024-312, released Dec. 19, 2024.) All state agencies may use the IRS rate for travel incurred on and after Jan. 1, 2025.
The Trip Optimizer law is still in place for determining the lowest cost of transportation for travel on state business. The new $0.70 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.
