In Montana, navigating mileage reimbursement involves understanding federal guidelines, specific state rules for public employees and workers' compensation, and common practices among private employers.
For businesses and employees in Montana, knowing these rates and rules is crucial for ensuring fair compensation and maintaining compliance.
Montana 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 Montana 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 Montana include:
- Montana State and Local Government Employee Rate: Montana Code Annotated (MCA) 2-18-503 provides that the mileage rate for state and local government employees using personal vehicles for official business is set by the Department of Administration. This rate typically aligns with the IRS standard business rate. Therefore, for 2026, the rate is 72.5 cents per mile (it was 70 cents per mile in 2025). The Montana Operations Manual for state employee travel also reflects this policy.
- Workers' Compensation Medical Travel: Montana law requires employers to reimburse injured employees for reasonable travel expenses incurred to obtain necessary medical services 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 20265 (and was 70 cents per mile in 2025).

Some Important Montana Mileage Reimbursement Laws
While Montana 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. Montana Minimum Wage Law
Montana's minimum wage is $10.55 per hour as of January 1, 2025. 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 state minimum wage threshold.
If it does, the employer could be in violation of Montana's wage laws.
Quick note: Businesses not covered by FLSA with gross annual sales of $110,000 or less may have a different rate, but FLSA-covered employees must receive the higher state or federal minimum.
2. Workers' Compensation (Montana Code Annotated Title 39, Chapter 71)
Montana 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
Montana 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. Public Employee Travel Regulations (MCA 2-18-503 & MOM Policy)
Montana has specific statutes and policies governing how public officers and state/local government employees are reimbursed for travel expenses, including mileage.
These mandate that the state mileage rate align with the IRS standard rate, ensuring public employees are reimbursed at a nationally recognized level.
Montana Mileage Reimbursement Law vs. Federal Law
Understanding the interplay between Montana'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 a Montana employee's unreimbursed mileage costs effectively reduce their pay below this federal threshold, the employer must provide sufficient reimbursement to meet the minimum wage.
However, since Montana's minimum wage is significantly higher, compliance with the state minimum usually ensures compliance with the federal minimum in this regard.
Montana State Law
- Montana's Minimum Wage Law establishes a rate higher than the federal standard, with annual adjustments.
- Specific provisions mandate mileage reimbursement for travel related to workers' compensation medical treatment, aligning with the IRS rate.
- The travel reimbursement rate for state and local government employees also aligns 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 Montana, the state minimum wage law provides a robust wage floor. State law aligns both workers' compensation and public 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 Montana employers.
