When Michigan employees use personal vehicles for work, there is no single state mileage rate that applies to every driver.
Private employers have flexibility in how they reimburse business driving. The IRS standard mileage rate is a common benchmark, while Michigan has separate rules for state employee travel and workers’ compensation.
Here’s what employers and drivers should know about Michigan mileage reimbursement in 2026.
What is the Michigan Mileage Reimbursement Rate for 2026?
Michigan does not set a single mileage reimbursement rate for private employers.
In practice, many employers look to the IRS standard mileage rate as a benchmark when reimbursing employees who drive personal vehicles for work.
The federal business mileage rate changed midway through 2026:
- 72.5 cents per mile from January 1 through June 30
- 76 cents per mile from July 1 through December 31
The IRS increased the rate following recent volatility in fuel prices. The revised 76-cent rate applies to qualifying business transportation expenses incurred on or after July 1, 2026.
For Michigan employers, 76 cents per mile is the current federal business mileage rate. It is a useful benchmark, but it is not a state-mandated rate for private employers.
Do Employers Have to Reimburse Mileage in Michigan?
Michigan does not establish a general cents-per-mile reimbursement requirement for private employers.
Employers therefore have room to create a mileage reimbursement policy that reflects how their employees drive and the needs of the business.
Federal wage requirements can still matter. Under the Fair Labor Standards Act, costs that are primarily for an employer’s benefit cannot reduce a covered employee’s earnings below the applicable minimum wage or cut into required overtime compensation.
For employers with drivers using their own vehicles regularly, a clear reimbursement policy can make business expenses easier to manage.
It should explain which trips qualify, how mileage is documented, how reimbursement is calculated, and when employees are paid.
Does Michigan Require Employers to Use the IRS Mileage Rate?
No. Michigan does not require private employers to use the IRS standard mileage rate.
The IRS rate is an optional method used to calculate certain deductible vehicle costs and amounts deemed substantiated under qualifying mileage allowance arrangements.
An employer might use the current 76-cent rate for a Cents-Per-Mile (CPM) program.
Another employer may use a reimbursement method that accounts for vehicle costs differently.
The right approach depends on factors such as how frequently employees drive, where they operate, and the vehicle costs associated with their work.
What Is the Michigan State Employee Mileage Rate?
Michigan has separate mileage reimbursement rules for qualifying state employee travel.
Under Michigan Civil Service rules, approved use of a personal vehicle can qualify for either a premium or standard mileage rate.
The premium reimbursement rate follows the IRS standard mileage rate unless otherwise ordered by the Civil Service Commission.
That makes the current premium rate 76 cents per mile following the IRS increase on July 1, 2026.
The standard mileage rate works differently. Michigan bases it on the average per-mile cost of a midsize state vehicle.
The state’s FY2026 Fleet Plan reports that the standard rate was 44 cents per mile in FY2025, but it does not publish a new FY2026 standard rate.
These rates apply to qualifying state employee travel. They do not establish what private Michigan employers must reimburse employees who use personal vehicles for work.
What Counts as Business Mileage in Michigan?
For federal tax purposes, business mileage generally means driving for a legitimate work-related purpose.
That can include traveling between work locations, visiting customers, making service calls, completing deliveries, or traveling to an off-site business meeting.
The main distinction is business use versus personal use. Business use involves driving connected to an employee’s work, while personal use includes trips made for personal reasons.
A regular trip between home and a main or regular workplace is generally considered personal commuting.
The IRS treats those commuting costs as personal even when the same vehicle is used for business driving during the workday.
Certain temporary work locations and qualifying home offices can follow different rules.
Employers should define business and personal mileage clearly so drivers understand which trips qualify under the company’s reimbursement policy.
What Mileage Records Should Michigan Employees Keep?
Accurate records help employers reimburse qualifying business driving and support the intended tax treatment of those payments.
IRS Publication 463 explains that vehicle records should document details including the mileage for each business use, the date, business destination, and business purpose.
Records should generally be created at or near the time the driving occurs.
A weekly mileage log can qualify as timely kept when it accurately accounts for vehicle use during the week. A mileage tracking app can also make recordkeeping easier for employees who drive frequently.
Whatever method an employer uses, consistency matters. Clear records make it easier to distinguish reimbursable business mileage from personal driving.
When Is Mileage Reimbursement Tax-Free in Michigan?
Federal accountable-plan rules are central to determining whether qualifying mileage reimbursements can be excluded from an employee’s taxable wages.
Under an accountable plan, three basic requirements apply:
- The expense has a business connection.
- The employee adequately accounts for the expense within a reasonable period.
- The employee returns any excess reimbursement within a reasonable period.
The IRS generally treats expenses accounted for within 60 days and excess reimbursements returned within 120 days as occurring within a reasonable period.
When accountable-plan requirements are satisfied, qualifying reimbursements generally are not reported as employee pay.
Michigan law also addresses withholding for certain employee expense reimbursements.
Michigan Compiled Laws § 141.652 provides that employers should not withhold Michigan tax from amounts paid to employees as reimbursement for expenses necessarily and actually incurred in performing their services when those expenses are deductible by the employer.
For mileage allowances, simply choosing a rate at or below the IRS benchmark does not establish the intended tax treatment. Documentation and program structure still matter.
What Is the Michigan Workers’ Compensation Mileage Rate for 2026?
Michigan workers’ compensation has separate mileage reimbursement rules for injured employees who travel in connection with their claims.
The Michigan Workers’ Disability Compensation Agency publishes travel reimbursement rates for injured employees.
The mileage rate was 72.5 cents per mile beginning January 1, 2026, and increased to 76 cents per mile effective July 1, 2026.
That makes 76 cents per mile the current Michigan workers’ compensation mileage rate for qualifying travel.
Workers’ compensation travel should be treated separately from an employer’s regular vehicle reimbursement program because it operates under its own rules and eligibility requirements.
Is There an Average Car Allowance in Michigan?
There is no official statewide average car allowance that Michigan private employers are expected to follow.
Vehicle costs can vary considerably between employees.
Annual business mileage, location, vehicle requirements, fuel consumption, insurance, maintenance, and other costs all affect what an employee spends to use a personal vehicle for work.
For employers, looking at the actual driving population provides a more useful starting point than relying on a generic statewide allowance.
An employee making occasional customer visits has a different cost profile from a salesperson or service technician who spends several days each week on the road.
What Reimbursement Programs Can Michigan Employers Use?
Michigan employers have several ways to reimburse employees who use personal vehicles for work.
Cents-Per-Mile (CPM) reimburses employees according to substantiated business mileage and a set per-mile rate. Employers can use the IRS standard mileage rate, although Michigan does not require private employers to match it.
Fixed and Variable Rate (FAVR) reimbursement accounts for two categories of vehicle costs. Fixed costs include expenses such as insurance and depreciation, while variable costs reflect expenses that change with driving, such as fuel and maintenance. The IRS recognizes FAVR arrangements and establishes specific requirements for qualifying programs.
A Tax-Free Car Allowance (TFCA) can use an accountable-plan structure to reimburse employees for qualifying business-related vehicle costs.
Each approach can reimburse employees for the business-related cost of using a personal vehicle for work, but the way reimbursement is calculated and administered differs.
Organizations with several types of drivers can also use a mixed program, assigning reimbursement methods based on driving patterns and job requirements.
How Should Michigan Employers Choose a Reimbursement Approach?
Start with how employees actually drive.
Consider annual business mileage, employee locations, vehicle requirements, regional costs, tax treatment, and how much administration the business wants to manage.
CPM can be straightforward for occasional drivers. FAVR can be useful for employees who drive regularly and face different fixed and operating costs.
A mixed approach can work for organizations with several distinct driver groups.
The goal is to choose a reimbursement approach that reflects business driving costs while remaining clear for employees and manageable for administrators.
