In Oklahoma, understanding mileage reimbursement involves looking at federal guidelines, specific state rules for public employees and workers' compensation, and common practices among private employers.
For businesses and employees in Oklahoma, knowing these rates and rules is crucial for ensuring fair compensation and maintaining compliance.
Oklahoma Mileage Reimbursement Rate
The most frequently referenced standard for business mileage reimbursement is the rate set by the Internal Revenue Service (IRS). For 2026, this rate changed mid-year: the IRS set the business rate at 72.5 cents per mile for the first half of the year, then raised it to 76 cents per mile effective July 1, 2026.
While Oklahoma private employers are not generally mandated by a specific state law to use the IRS rate for all business mileage, many choose to do so because:
- It provides a nationally recognized standard calculated to reflect the average costs associated with operating a vehicle for business, including fuel, maintenance, insurance, and depreciation.
- Reimbursements made at or below the current IRS standard business rate are generally non-taxable income for the employee, provided that proper and accurate records are maintained.
- It offers a consistent and transparent method for compensating employees fairly for the business use of their personal vehicles.
For 2026, the standard IRS mileage rates are different for H1 and H2.
For H1 2026 (Jan - June):
- Business Use: 72.5 cents per mile
- Medical/Moving: 20.5 cents per mile (Note: Moving expenses deduction is generally only available for active-duty military members)
- Charitable: 14 cents per mile
For H2 2026 (July - Dec):
- Business Use: 76 cents per mile, up 3.5 cents from H1 2026.
- Medical/Moving: 23.5 cents per mile, up 3 cents from H1 2026. (Note: Moving expenses deduction is generally only available for active-duty military members)
- Charitable: 14 cents per mile, no change.
Other relevant rates in Oklahoma include:
- Oklahoma State Employee Rate: The State of Oklahoma, under the State Travel Reimbursement Act (74 O.S. Supp. 2023, § 500.4), sets the reimbursement rate for state employees using personal vehicles for official business. This rate is aligned with the current IRS standard business rate. Therefore, for 2026, the rate is 72.5 cents per mile.
- Workers' Compensation Medical Travel: Oklahoma law (Title 85A, Administrative Workers' Compensation Act) requires employers to reimburse injured employees for reasonable travel expenses to obtain necessary medical treatment for work-related injuries. The mileage reimbursement rate for this purpose is the same as the rate allowed for state employees, meaning it is 72.5 cents per mile for 2026.

Some Important Oklahoma Mileage Reimbursement Laws
While Oklahoma doesn't have a statewide law mandating mileage reimbursement for all private-sector employees in every instance, several state laws and federal regulations influence how employers should handle these expenses:
1. Oklahoma Minimum Wage Act (Title 40, Oklahoma Statutes)
Oklahoma's primary minimum wage is $7.25 per hour for employers with ten or more full-time employees or with annual gross sales over $100,000. Most employers are also subject to the federal minimum wage of $7.25 per hour.
A critical point is that any unreimbursed business expenses an employee is required to incur, such as mileage for using a personal vehicle for work, should not cause their effective hourly earnings to fall below this applicable minimum wage threshold. I
f it does, the employer could be in violation of Oklahoma and/or federal wage laws.
2. Workers' Compensation (Title 85A, Oklahoma Statutes)
Oklahoma law ensures that employees injured on the job receive reimbursement for necessary travel to obtain medical treatment.
The mileage rate for this is tied to the state employee travel reimbursement rate, which aligns with the IRS standard business rate (76 cents per mile for 2026).
3. No General Mandate for Private Employers
Oklahoma law does not specifically obligate private employers to offer mileage reimbursement for general business use of personal vehicles. Therefore, a company's internal policy plays a significant role.
However, many employers choose to reimburse as a good business practice and to avoid potential minimum wage complications.
4. State Travel Reimbursement Act (74 O.S. § 500.1 et seq.)
This act governs how state officers and employees are reimbursed for travel expenses, including mileage.
It mandates that the state mileage rate align with the IRS standard rate, ensuring state employees are reimbursed at a nationally recognized level.
Oklahoma Mileage Reimbursement Law vs. Federal Law
Understanding the interplay between Oklahoma's state context and federal laws is essential for proper mileage reimbursement:
Federal Law (FLSA)
The Fair Labor Standards Act (FLSA) is the primary federal law affecting this area. It mandates that employees receive at least the federal minimum wage ($7.25 per hour) "free and clear" of any business expenses incurred primarily for the employer's benefit.
If an Oklahoma employee's unreimbursed mileage costs effectively reduce their pay below this federal threshold, the employer must provide sufficient reimbursement to meet the minimum wage.
Since Oklahoma's primary minimum wage is the same as the federal rate, compliance with one generally ensures compliance with the other.
Oklahoma State Law
- Oklahoma's Minimum Wage Act establishes a rate of $7.25 per hour for most employers.
- Specific provisions mandate mileage reimbursement for travel related to workers' compensation medical treatment, aligning with the IRS rate.
- The State Travel Reimbursement Act also aligns the reimbursement rate for state employees with the IRS standard rate.
IRS Regulations
The IRS sets the standard mileage rates (e.g., 76 cents/mile for business in 2026) for tax purposes.
These rates are not legal mandates for employers to reimburse but are crucial for determining the non-taxable amount of reimbursement under an accountable plan.
Using these rates helps ensure that reimbursements aren't considered taxable income for employees and are deductible for employers.
In Oklahoma, federal and state minimum wage laws provide a foundational wage floor. State law aligns both workers' compensation and state employee travel reimbursement with the IRS standard rates. IRS guidelines offer a practical framework for the amount and tax treatment of reimbursements, commonly adopted by Oklahoma employers.
