Oklahoma Mileage Reimbursement 2026: Up to 76 Cents, Capped by Statute

Oklahoma's State Travel Reimbursement Act speaks in limits. Section 500.4 lets an agency head approve a privately owned vehicle for official travel, and caps what that driver can be paid at the federal business rate.

An agency may pay less than the cap. The law fixes the top of the range and leaves the amount to the agency that approved the travel, which is why a claim should record both the rate and the approval.

• Actual business miles, taken from a GPS reading or from a map and the vicinity of the business.
• A state vehicle or a motor pool rental first, when one is available.
• An agency head's approval for a personal vehicle on official travel.
• One fiscal year per claim, so miles from an earlier year need their own claim.
• The agency's travel claim form, signed by the traveler and by the approving official.

The statute points at the Internal Revenue Code rather than at a state schedule, so the cap moved on July 1 without a rule change or an agency decision.

The act binds state agencies and the travelers they reimburse. It says nothing about a private payroll, and the state publishes no private mileage rate, so the employer's policy decides. Most policies take the federal business rate, which is 72.5 cents per mile through June 30, 2026 and 76 cents per mile from July 1.

• Ask which figure the employer authorized, because the state's own rule sets a ceiling and not a rate.
• Keep the GPS track or the map printout, since the act measures miles that way rather than by estimate.
• File before the fiscal year closes, because a claim cannot carry miles from two years.

The Oklahoma Office of Management and Enterprise Services publishes these figures. It covers state agencies and the travelers they reimburse, through the cap in the State Travel Reimbursement Act. A private employer owes nothing under it.

The amounts are ceilings. An agency may reimburse less, and the approval for the trip is what fixes the figure it pays.

The cap follows the federal business rate because the statute points at the Internal Revenue Code, not at a state schedule.

The IRS moved the business standard mileage rate mid-year, so a 2026 trip prices by its date. This is the benchmark an employer's rate method usually follows.

The IRS has not published a standard mileage rate for 2027. Until it does, two things decide what a trip pays: the year you drove it and the date within that year. A 2026 trip pays 72.5 cents per mile through June 30 and 76 cents per mile from July 1. Miles driven from January 1, 2027 will use whatever figure the IRS publishes next.

The next year's rate has arrived in December in each of the last nine years, between December 14 and December 31. An announcement is not always the last word. The IRS raised the 2026 figure on July 1, halfway through the year, so a 2027 claim may need two rate periods.

A state that publishes a rate for its own travelers follows its own calendar, so it can publish the next period before the IRS does. A private employer's rate changes when its own policy changes, or when the benchmark that policy follows moves. It does not change because the calendar year turns.
