Oklahoma mileage reimbursement rates & calculator

Did you know? Under Oklahoma's State Travel Reimbursement Act (74 O.S. § 500.4), mileage for state employees is reimbursed at rates aligned with IRS standards, and yes, it's mandatory. 

However, while not compulsory for private employers like you, it's a common practice when aligning with federal rates. Additionally, Oklahoma's Administrative Workers' Compensation Law (§85A-50) mandates mileage reimbursement for job-related medical visits, which is essential for your employees' financial well-being.

Furthermore, adopting fair mileage reimbursement practices, even though state law doesn't make it a legal mandate for you, will offer dual benefits.

  • Keep your business aligned with the Minimum Wage Law

Oklahoma mileage reimbursement laws

In Oklahoma, mileage reimbursement is governed by specific statutes, each catering to different groups such as state employees, county officers, Workers' Compensation claimants, and individuals covered under the Minimum Wage Act. 

Below is a detailed exploration of these codes you must know as an employer.

State employees’ mileage reimbursement code §74-500.4[1]

If you are an employer within the Oklahoma state system, you must reimburse state employees for mileage at 67 cents per mile when they use their private vehicles for official state business. 

Remember, the rate is aligned with the IRS standard mileage rate. When employees submit their mileage claims, make sure the distances they report do not exceed those listed on the latest Transportation Commission road map. 

It's also important to note that vicinity travel — those little trips made around the primary place of business — must be documented separately. 

Code §85A-50 of the administrative workers' compensation act[2]

As a private employer in Oklahoma, it's crucial to be aware that if one of your employees is injured on the job and needs to travel outside their hometown for medical treatment, you are responsible for reimbursing their travel expenses. 

You must do the following. 

  • Cover mileage for any travel over 20 miles round-trip
  • Offer reimbursement claims up to 600 miles round-trip. 

This policy ensures your employees can access necessary medical care without undue financial burden.

Oklahoma minimum wage act 40 O.S. § 197.1

Understanding the Oklahoma Administrative Minimum Wage Act is crucial whether you're managing state employees or running a private business. The act sets the minimum wage at $7.25 per hour, matching the federal rate, and outlines mileage reimbursement exemptions for: 

  • Agricultural workers
  • Domestic employees in private homes
  • Newspaper carriers
  • Employees of certain interstate carriers and volunteers. 

Your non-compliance with these wage requirements, including mileage reimbursements, could result in:

  • Fines up to $500
  • Misdemeanor charges

Federal vs. Oklahoma mileage reimbursement rules

While the federal guideline sets the 2024 mileage rate at $0.67 per mile, which Oklahoma adopts, the state also mandates certain reimbursements not covered federally. For example, under Oklahoma's Administrative Workers' Compensation Act, you must reimburse employees for medical travel over 20 miles round trip, up to 600 miles. 

Additionally, Oklahoma permits reimbursement for county officers and employees at potentially lower rates decided by the Board of County Commissioners, differing from the federal standard.
