Kentucky does not set a general mileage reimbursement rate that private employers must pay employees who use their personal vehicles for work.
That means private employers can choose a reimbursement method that fits their workforce, provided they follow the applicable federal tax rules and any other employment requirements that apply to their organization.
The IRS standard mileage rate is one common benchmark. In 2026, the business mileage rate changed midyear:
- 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 business mileage rate to 76 cents per mile beginning July 1 following increases in fuel prices.
Kentucky state employees follow a separate reimbursement system. For July 1 through September 30, 2026, the Kentucky state employee mileage reimbursement rate is 47 cents per mile.
Here’s what Kentucky employers should know about mileage reimbursement rates, taxes, and reimbursement options in 2026.
What Is the Kentucky Mileage Reimbursement Rate for 2026?
There is no single Kentucky mileage reimbursement rate that applies to every employer.
For private employers, Kentucky does not establish a generally applicable cents-per-mile rate for employees using personal vehicles for work.
Companies can instead develop a mileage reimbursement policy based on their employees, business-driving patterns, and reimbursement strategy.
The IRS standard mileage rate is often used as a reference point.
The IRS originally set the 2026 business rate at 72.5 cents per mile. It later increased that rate to 76 cents per mile effective July 1, 2026 because of recent increases in fuel prices.
The IRS business rate applies to the business use of cars, vans, pickups, and panel trucks. It reflects more than fuel alone.
The IRS determines the business rate using a study of the fixed and variable costs associated with operating a vehicle.
That makes the IRS rate a useful federal tax benchmark, but it does not mean every Kentucky employer needs to reimburse every employee at 76 cents per mile.
Do Employers Have to Reimburse Mileage in Kentucky?
Kentucky does not establish a general statewide cents-per-mile reimbursement requirement for private employers.
The state mileage rules discussed below apply to public-sector travel and state employees.
Private organizations therefore need to determine their own reimbursement approach based on applicable tax rules, company policy, employee driving patterns, and any contractual or industry-specific obligations.
An employer might:
- reimburse employees using the IRS standard mileage rate,
- establish another cents-per-mile rate,
- reimburse actual vehicle expenses, or
- use a structured reimbursement program such as FAVR.
Whatever method an organization chooses, its policy should clearly explain which trips qualify as business mileage, how employees document those trips, how reimbursement is calculated, and when claims need to be submitted.
Employers should also distinguish business driving from ordinary commuting.
For federal tax purposes, travel between an employee’s home and regular workplace is generally considered commuting rather than deductible business transportation.
Kentucky’s state employee rules make a similar distinction. 200 KAR 2:006 states that commuting between a residence and an official or alternate work station generally is not reimbursable mileage.
What Is the Kentucky State Employee Mileage Rate?
Kentucky state employees follow a separate reimbursement system from private-sector employees.
Under 200 KAR 2:006, reimbursement for authorized use of a privately owned vehicle is paid at a rate designated by the Office of the Controller.
The regulation states that the rate is adjusted based on the AAA Daily Fuel Gauge Report for Kentucky for regular gasoline.
Kentucky publishes the rate quarterly through the state’s Finance and Administration Cabinet.
For 2026, the published rates so far are:
The October through December 2026 rate had not yet been published as of September 17, 2026. The state travel page is updated quarterly.
These rates apply to eligible state travel. Private Kentucky employers should not treat the state employee mileage rate as a required rate for their own employees.
Is the IRS Mileage Rate Required in Kentucky?
No. The IRS standard mileage rate is an optional federal rate, not a Kentucky law requiring private employers to pay employees that amount.
For July 1 through December 31, 2026, the business mileage rate is 76 cents per mile. The IRS describes the standard mileage rate as an optional method for calculating the deductible costs of operating an automobile for business purposes. Taxpayers may generally use actual vehicle costs instead when permitted.
For employers, the rate also functions as an important deemed-substantiation rate for mileage allowances under federal tax rules.
That distinction matters.
The IRS rate helps answer a tax and substantiation question. Employers still need to answer a separate reimbursement design question:
What method makes sense for the way our employees actually drive?
An employee driving a few hundred business miles a month can have a very different cost profile from a field employee driving 20,000 business miles a year.
Fuel prices, insurance costs, vehicle requirements, geography, and annual mileage can all affect the real cost of using a personal vehicle for work.
Is Mileage Reimbursement Taxable in Kentucky?
Mileage reimbursement can generally be excluded from taxable wages when it is paid under a qualifying accountable plan.
Under IRS rules, an accountable plan must meet three basic requirements:
- The expenses must have a business connection.
- Employees must adequately account for the expenses within a reasonable period.
- Employees must return amounts that exceed their substantiated expenses within a reasonable period.
Amounts properly paid under an accountable plan are not treated as wages and generally are not subject to federal income tax withholding, Social Security, Medicare, or FUTA taxes.
For a mileage allowance, employees still need to substantiate the underlying business use, including information such as the number of business miles driven and the business purpose of the travel.
If an employer pays a standard mileage allowance above the federal deemed-substantiated amount, the excess generally must be treated as wages unless another qualifying reimbursement method applies.
This is one reason accurate business mileage tracking matters. Good records help employers support both reimbursement calculations and tax treatment.
What Mileage Reimbursement Methods Can Kentucky Employers Use?
The IRS standard mileage rate is one option, but it is not the only way to reimburse employees who drive personal vehicles for work.
Cents-Per-Mile (CPM)
A Cents-Per-Mile reimbursement pays employees a set amount for each eligible business mile.
It is easy to understand and can work well for employees with occasional or relatively low business mileage.
Because reimbursement increases directly with miles driven, however, program costs can fluctuate significantly for high-mileage workforces.
Fixed and Variable Rate (FAVR)
A Fixed and Variable Rate reimbursement separates vehicle costs into fixed and variable components.
Fixed costs can include expenses such as depreciation, insurance, registration, and license fees.
Variable costs can include fuel, oil, tires, maintenance, and repairs. IRS guidance specifically recognizes this fixed-plus-variable structure.
This allows reimbursement to reflect factors such as geography and mileage rather than applying one identical rate to every driver.
FAVR is an IRS-recognized reimbursement method with its own requirements. For 2026, the IRS sets the maximum standard automobile cost used to calculate a qualifying FAVR allowance at $61,700.
Employers considering FAVR should make sure the program satisfies the requirements in IRS Revenue Procedure 2019-46.
Tax-Free Car Allowance
A Tax-Free Car Allowance can give employers the predictability of an allowance while using mileage substantiation and accountable-plan rules to support tax-free treatment.
Tax-Free Car Allowance is a way of structuring vehicle reimbursement rather than a separate IRS-defined reimbursement category.
The tax treatment depends on whether the arrangement satisfies the applicable accountable-plan and substantiation requirements.
For organizations currently providing a flat taxable allowance, an accountable reimbursement arrangement can reduce the amount of reimbursement treated as wages when it is properly structured and documented.
How Should Kentucky Employers Build a Mileage Reimbursement Policy?
A strong mileage reimbursement policy starts by defining how business driving works within the organization.
The policy should explain:
- what counts as reimbursable business mileage,
- how commuting and personal driving are treated,
- which reimbursement method the company uses,
- what documentation employees need to provide, and
- how and when mileage claims are submitted and approved.
Employers should also review the program periodically.
Fuel prices, insurance premiums, maintenance costs, and other vehicle expenses change over time.
The IRS’s midyear mileage rate increase in 2026 is a good example of how quickly vehicle-cost assumptions can change.
Accurate records matter as well.
Accountable-plan reimbursements require employees to substantiate their business expenses, so organizations should have a consistent process for recording business mileage and business purpose.
Find the Right Mileage Reimbursement Program for Your Kentucky Workforce
Kentucky employers have room to choose a reimbursement approach that fits their workforce.
For employees who drive occasionally, a straightforward cents-per-mile program may be enough. Organizations with frequent or high-mileage drivers may benefit from a FAVR program that accounts separately for fixed and variable vehicle costs. Others may prefer an accountable allowance model that provides more predictable payments.
The goal is to match reimbursement to the way employees actually drive while maintaining accurate mileage records and appropriate tax treatment.
