If employees use their personal vehicles for work in Mississippi, there is no single mileage reimbursement rate that every private employer is required to pay.
Many employers use the IRS standard mileage rate as a benchmark. In 2026, that rate changed mid-year.
The optional business standard mileage rate is 72.5 cents per mile for January 1 through June 30, 2026, and 76 cents per mile beginning July 1, 2026.
The IRS says the mid-year adjustment resulted from recent increases in fuel prices.
Mississippi also has separate mileage reimbursement rules for state employees, local government employees, and workers’ compensation travel.
Here is what employers and employees should know about Mississippi mileage reimbursement in 2026.
What Is the Mississippi Mileage Reimbursement Rate for 2026?
Mississippi does not have a mandatory mileage reimbursement rate for private employers in 2026.
Employers that reimburse business mileage often use the IRS standard mileage rate as a benchmark, which is 72.5 cents per mile through June 30, 2026, and 76 cents per mile beginning July 1, 2026.
The two IRS business mileage rates for 2026 are:
- January 1 through June 30, 2026: 72.5 cents per business mile
- July 1 through December 31, 2026: 76 cents per business mile
The IRS increased the rate mid-year because of recent increases in fuel prices. The revised rate applies to deductible business transportation expenses paid or incurred on or after July 1.
For employee mileage allowances, it applies when the allowance is paid on or after July 1 and relates to transportation expenses the employee paid or incurred on or after July 1.
The IRS standard mileage rate is optional. It provides a federal benchmark for calculating business vehicle costs rather than establishing a mandatory Mississippi reimbursement rate.

Do Private Employers Have to Reimburse Mileage in Mississippi?
Mississippi does not have a general state law establishing a mandatory per-mile reimbursement rate for ordinary business driving by private-sector employees.
That gives private employers flexibility in how they structure mileage reimbursement.
Employers should still consider employment agreements, collective bargaining agreements, written company policies, and any other requirements that apply to a particular workforce or type of travel.
For employers whose employees regularly use personal vehicles for work, a clear mileage reimbursement policy can establish which trips qualify, how mileage should be documented, which reimbursement method applies, and when payments are made.
It is also important to distinguish ordinary private-sector business mileage from the specific reimbursement rules governing Mississippi public employees and workers’ compensation travel.
When Can Mileage Reimbursement Be Tax-Free?
Mileage reimbursement can generally be excluded from federal taxable wages when an employer's reimbursement arrangement meets IRS accountable-plan requirements.
Under IRS rules, an accountable plan generally requires that the expense have a business connection, the employee adequately account for the expense within a reasonable period, and the employee return excess reimbursement or allowances within a reasonable period.
When those requirements are satisfied, qualifying reimbursements generally are not treated as wages.
Employees also need adequate records supporting their business driving. IRS rules require sufficient documentation of qualifying vehicle expenses and business use.
The reimbursement rate alone does not determine whether a payment is tax-free. Program structure, substantiation, and treatment of excess reimbursements all matter.

What Counts as Business Mileage in Mississippi?
Business mileage generally involves driving for a legitimate business purpose.
An employee's ordinary commute between home and a regular workplace is generally considered personal travel for federal tax purposes.
Qualifying business travel can include driving from an office to a customer location, traveling between work locations during the day, making deliveries or service calls, and traveling to certain temporary work locations.
IRS rules contain additional requirements for temporary work locations and qualifying home offices, so employers should clearly define eligible trips in their mileage reimbursement policies.
Clearly distinguishing business versus personal vehicle use can make mileage reporting easier for employees while helping employers calculate reimbursements consistently.
What Is the Mississippi State Employee Mileage Rate for 2026?
Mississippi has specific mileage reimbursement rules for state officers and employees.
Under Mississippi Code § 25-3-41, authorized state officers and employees traveling on official business in privately owned vehicles receive the mileage reimbursement rate allowed to federal employees for privately owned vehicle travel.
For the first half of 2026, the federal privately owned automobile rate was 72.5 cents per mile when a personal automobile was authorized or no government automobile was available, with a lower 20.5-cent rate when a government automobile was authorized and available.
GSA adjusted the federal privately owned vehicle rates mid-year. For federal travel on or after July 1, 2026, the rates are:
76 cents per mile when a personal automobile is authorized or no government-owned automobile is available.
23.5 cents per mile when a government-owned automobile is authorized and available but the traveler chooses to use a personal automobile.
The distinction matters because the 23.5-cent rate is not simply another version of the IRS business mileage rate.
It applies to the specific federal travel situation in which a government-furnished automobile was authorized and available.
Current federal privately owned vehicle rates are published by the U.S. General Services Administration.
Mississippi law also addresses county and municipal employees.
Section 25-3-41 establishes a base reimbursement of 20 cents per mile for authorized official travel in a privately owned vehicle.
A county or municipality may authorize a higher rate, up to the mileage reimbursement rate authorized for Mississippi state employees.
These public-sector rules do not establish a reimbursement rate for private Mississippi employers.
How Does Workers’ Compensation Mileage Work in Mississippi?
Workers’ compensation travel is handled separately from ordinary employee mileage reimbursement.
Mississippi Workers’ Compensation Commission guidance states that a claimant must be reimbursed for travel to obtain medical treatment under Mississippi workers’ compensation law.
That includes qualifying travel to a pharmacy to obtain medication or supplies needed to treat a compensable injury.
Because workers’ compensation mileage is governed separately from private-employer mileage reimbursement and state employee travel, employers and injured workers should check the Mississippi Workers’ Compensation Commission for the current rate and requirements that apply when the travel occurs.
What Mileage Reimbursement Options Can Mississippi Employers Use?
Private employers can choose from several approaches for reimbursing employees for the real, business-required costs of owning and operating personal vehicles for work.
Cents-Per-Mile (CPM)
Cents-Per-Mile (CPM) reimburses employees for the real, business-required costs of using a personal vehicle for work through a set amount for each qualifying business mile.
Employers may use the IRS standard mileage rate or another rate appropriate for their program. CPM can be straightforward for occasional drivers because reimbursement directly follows documented business mileage.
Employers using an accountable mileage allowance should also consider the applicable IRS rules for substantiation and excess reimbursements.
Fixed and Variable Rate (FAVR)
Fixed and Variable Rate (FAVR) reimburses employees for the real, business-required fixed and variable costs of owning and operating personal vehicles for work.
Fixed costs can include depreciation, insurance, registration, and related ownership expenses. Variable costs can include fuel, maintenance, and tires.
FAVR is an IRS-recognized mileage allowance methodology with specific requirements.
The IRS also establishes an annual maximum standard automobile cost for qualifying FAVR plans. For 2026, that amount is $61,700, according to IRS guidance for 2026.
Separating fixed and variable expenses can help account for differences in employee mileage and geographically variable vehicle costs.
Tax-Free Car Allowance (TFCA)
Tax-Free Car Allowance (TFCA) is an accountable reimbursement arrangement designed to reimburse employees for the real, business-required costs of using personal vehicles for work.
Tax-free treatment depends on satisfying applicable IRS accountable-plan requirements, including adequate substantiation and appropriate treatment of excess payments.
Companies with different driver populations can also consider a mixed mileage reimbursement strategy.
For example, an employer may use FAVR for employees with substantial recurring business mileage and CPM for employees who drive less frequently.
How Should Mississippi Employers Manage Mileage Reimbursement?
A clear mileage reimbursement policy gives employees and administrators a consistent process to follow.
The policy should explain which trips qualify as business mileage, how employees record those trips, which reimbursement method applies, and when payments are processed.
Accurate mileage records also support accountable-plan requirements and give Finance, HR, and Operations teams better visibility into business driving.
Employers should review their programs regularly.
The IRS's mid-year adjustment in 2026 shows why reimbursement benchmarks need ongoing attention.
Fuel, insurance, maintenance, driving patterns, and tax requirements can also change over time.
