Ohio employees who drive their own cars for work take on real costs along the way, from fuel and maintenance to insurance and depreciation.
Mileage reimbursement is one way employers can help cover those business-related expenses.
In Ohio, private employers have flexibility in how they approach reimbursement. Many look to the IRS standard mileage rate as a benchmark, but it is not a state-required rate.
Here’s what employers and drivers need to know about Ohio mileage reimbursement in 2026.
What Is the Ohio Mileage Reimbursement Rate for 2026?
Ohio does not set a single mileage reimbursement rate for private employers.
Many employers use 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 to 76 cents per mile for qualifying business transportation expenses incurred on or after July 1, 2026.
For private Ohio employers, that rate is a federal benchmark. Companies can choose another reimbursement method based on their workforce and business driving needs.
Do Employers Have to Reimburse Mileage in Ohio?
Ohio does not establish a general mileage reimbursement requirement for private employers.
That means employers have flexibility in deciding whether to reimburse employees for business driving and how that reimbursement is calculated.
Many businesses create a clear mileage reimbursement policy so employees know what travel qualifies and what documentation they need to provide.
Employers that choose to reimburse mileage can use the IRS standard mileage rate as a benchmark, set another cents-per-mile rate, or use a different reimbursement structure.
Whatever approach a company chooses, the policy should clearly explain which trips qualify, how employees track business mileage, how reimbursement is calculated, and when payments are made.
Does Ohio Require Employers to Use the IRS Mileage Rate?
No. Private Ohio employers are not required to use the IRS standard mileage rate.
The IRS describes the standard mileage rate as an optional method for calculating certain vehicle costs.
Employers can use it as a benchmark for a Cents-Per -Mile (CPM) reimbursement program, but other reimbursement structures are available.
For employers, the right approach depends on how employees actually drive.
Business mileage, location, vehicle requirements, fuel costs, insurance, and other operating expenses can all affect the cost of using a personal vehicle for work.
What Is the Ohio State Employee Mileage Rate?
Ohio has separate rules for state employees who use privately owned vehicles for official state business.
Under Ohio Administrative Code Rule 126-1-02, mileage reimbursement can be authorized at a rate up to the IRS business standard mileage rate, at the discretion of the director of the Office of Budget and Management.
The rule generally prevents the reimbursement rate from falling below 45 cents per mile unless the IRS rate itself falls below that amount.
The current version of the rule requires the director to review the rate at least annually.
This distinction matters. Ohio's rule does not say that the state employee mileage rate automatically becomes whatever rate the IRS publishes.
The rule also says employees generally cannot receive mileage reimbursement for travel between their residence and assigned work location.
When an employee travels from home to an alternate work location, reimbursement is limited based on the distance to that location minus the employee's normal commute.
Ohio also limits personal-vehicle reimbursement when using a state-owned vehicle would be more cost-effective. Additional approval requirements can apply when an employee exceeds that threshold.
These rules apply to qualifying state travel. They do not establish a required reimbursement rate for private Ohio employers.
What Counts as Business Mileage in Ohio?
For federal tax purposes, business mileage generally involves driving for a legitimate work-related purpose.
That can include traveling between work locations, visiting customers, making service calls, completing deliveries, or attending an off-site business meeting.
The important distinction is business use versus personal use.
A regular trip between an employee's home and regular workplace is generally considered personal commuting rather than business transportation.
Different rules can apply to temporary work locations and employees whose homes qualify as their principal place of business.
Employers should define these categories clearly in their mileage policies so employees understand which trips qualify for reimbursement.
What Mileage Records Should Ohio Employees Keep?
Accurate mileage records help employers reimburse qualifying business travel and support the intended tax treatment of those payments.
IRS Publication 463 explains that records for vehicle expenses should include information such as the mileage for each business use, the date, destination, and business purpose.
Records should generally be created at or near the time of the trip.
The IRS also says that a weekly mileage log can qualify as a timely kept record when it accurately accounts for vehicle use during the week.
Employees who drive frequently can use a mileage tracking app to make this easier. Whatever method an employer chooses, the goal is consistent documentation that clearly separates business driving from personal mileage.
When Is Mileage Reimbursement Tax-Free in Ohio?
Mileage reimbursement can generally be excluded from an employee's taxable wages when it meets federal accountable-plan requirements.
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 provides timing safe harbors for these requirements.
Expenses accounted for within 60 days and excess reimbursements returned within 120 days are generally treated as occurring within a reasonable period.
When the accountable-plan requirements are met, qualifying reimbursements generally are not reported as employee pay.
Using the IRS mileage rate by itself does not establish the intended tax treatment. Documentation and the structure of the reimbursement arrangement still matter.
For most employees, unreimbursed business mileage also cannot simply be deducted on a federal tax return.
Federal law now permanently disallows miscellaneous itemized deductions for unreimbursed employee travel expenses.
Specific exceptions and separate deductions remain available for certain workers and expenses, so employees with unusual circumstances should review the current IRS rules.
What Is the Ohio Workers' Compensation Mileage Rule?
Ohio workers’ compensation handles qualifying travel separately from ordinary business mileage.
Under Ohio Administrative Code Rule 4123-6-40, an injured worker can receive reimbursement for reasonable and necessary travel expenses in specified circumstances.
For example, reimbursement can apply when an injured worker is ordered or authorized to undergo a medical examination outside their city or community.
It can also apply when necessary, pre-authorized treatment for an allowed work-related condition is unavailable within the worker’s city or community.
In those situations, travel generally must exceed 45 miles round trip to qualify.
A different rule applies when an employer asks an injured worker to attend an examination by a physician of the employer’s choice.
In that situation, the 45-mile minimum does not apply, and the employer is responsible for the travel expenses outlined by the rule.
For qualifying automobile travel, reimbursement is calculated on a per-mile basis using the applicable Ohio Bureau of Workers’ Compensation payment rate.
Because workers’ compensation travel follows its own eligibility and payment rules, employers should treat it separately from their regular vehicle reimbursement program.
Is There an Average Car Allowance in Ohio?
There is no official statewide average car allowance that Ohio private employers are expected to follow.
Vehicle costs can vary significantly from one employee to another.
Annual business mileage, location, vehicle requirements, insurance, fuel, maintenance, and depreciation all affect what an employee spends to use a personal vehicle for work.
An employee who drives to a customer meeting a few times per month has a very different cost profile from a field employee who spends several days each week on the road.
For employers, looking at the actual driving population provides a more useful starting point than relying on a generic Ohio average.
What Reimbursement Programs Can Ohio Employers Use?
Ohio employers have several options for reimbursing employees who use personal vehicles for work.
Cents-Per-Mile (CPM) reimburses employees based on substantiated business mileage and a set per-mile rate. The IRS standard mileage rate can serve as a benchmark, although private Ohio employers do not have to match it.
Fixed and Variable Rate (FAVR) reimbursement separates vehicle expenses into fixed and variable costs. Fixed costs can include insurance and depreciation, while variable costs include expenses such as fuel and maintenance. IRS rules establish specific requirements for qualifying FAVR arrangements.
A Tax-Free Car Allowance (TFCA) can use an accountable-plan structure to reimburse qualifying business-related vehicle costs.
Each approach can reimburse employees for the business-related cost of using a personal vehicle for work. The way those costs are calculated and administered differs.
Organizations with different types of drivers can also use a mixed program that assigns reimbursement methods based on driving patterns and job requirements.
How Should Ohio Employers Choose a Reimbursement Approach?
Start with how employees actually drive.
Consider annual business mileage, driver locations, vehicle requirements, regional costs, tax treatment, and how much administration the business wants to manage.
CPM can be straightforward for employees who drive occasionally.
FAVR can be useful for regular drivers whose fixed and operating costs vary by location. A mixed program can work for organizations with several distinct driver groups.
The goal is a reimbursement approach that reflects business driving costs while remaining clear for employees and manageable for administrators.
