How Much Is Mileage Reimbursement? IRS Rates, Taxes, and Records

The IRS standard mileage reimbursement rate for business driving in 2026 is 72.5 cents per mile, up from 70 cents in 2025.¹ That figure is what most employers pay employees who drive their own cars for work, and what self-employed workers deduct on their tax returns. Lower rates apply to medical trips, qualified military moves, and charitable driving. How much you actually receive, and whether it’s taxed, depends on the type of travel, your employer’s reimbursement plan, and how well you document each trip.

2026 IRS Mileage Rates

The IRS updates the business rate each year based on an independent study of what it costs to own and operate a vehicle, including fuel, insurance, depreciation, maintenance, and registration. For 2026:

Business driving: 72.5 cents per mile.¹
Medical care and qualified moves by active-duty members of the Armed Forces: 20.5 cents per mile.¹
Charitable volunteering: 14 cents per mile. This rate is set by federal statute and does not change year to year unless Congress acts.²

The medical and moving rate is lower because it reflects only variable costs like fuel and oil, not the fixed ownership costs built into the business rate. The IRS applies the same rates to gasoline, diesel, hybrid, and fully electric vehicles.³

Business parking fees and tolls are not included in the per-mile figure. You can claim or be reimbursed for those on top of your mileage.⁴ Parking at your regular workplace is a personal commuting cost and does not qualify.⁵

Which Miles Qualify

Not every trip in your personal car counts. The line between business travel and commuting is where most disputed reimbursements fall apart.

Business miles include trips between two work locations, drives from your office to a client site, travel between job sites during the day, and trips from a home office that serves as your principal place of business to another work location. Your daily drive from home to your regular workplace is a personal expense, no matter how far it is or whether you take business calls along the way.⁵

There’s an exception for temporary work locations. If your employer sends you to a job site outside the metro area where you live and the assignment is temporary, the drive from home to that site can qualify. If your home is your principal place of business, trips from home to any other work location in the same trade or business qualify as well, even when the other location is permanent.⁵

How the Payment Is Taxed

Mileage reimbursement can arrive completely tax-free, or it can be treated as ordinary wages. The difference is whether your employer runs an accountable plan.

Accountable Plans

An accountable plan meets three tests: the expense has a business connection, the employee reports it to the employer within a reasonable time, and the employee returns any overpayment within a reasonable time.⁵ The IRS treats these deadlines as reasonable:

Advances received within 30 days of the expense.
Expenses reported to the employer within 60 days of being incurred.
Excess reimbursement returned within 120 days of the expense.

When the employer pays at or below the IRS rate and all three rules are satisfied, the reimbursement does not appear as wages on your W-2 and no tax is owed on it.⁵

Payments Above the IRS Rate

Some employers pay more than 72.5 cents per mile. The portion up to the IRS rate stays tax-free and is reported under code L in box 12 of your W-2. The excess is taxable wages, shows up in box 1, and is subject to income tax and payroll tax withholding.⁶

Nonaccountable Plans

If the employer skips any of the three accountable-plan rules, for example by paying a flat monthly car allowance without requiring expense reports, the whole payment is taxable wages. It goes into box 1 of your W-2, and you owe income tax and payroll taxes on all of it.⁵

Whether Your Employer Has to Pay

No federal law requires every employer to reimburse mileage. The Fair Labor Standards Act sets an indirect floor: if unreimbursed vehicle expenses push an employee’s effective pay below the federal minimum wage of $7.25 per hour, the Department of Labor treats it as an illegal deduction from wages and can order back pay.⁷

In practice, the minimum-wage floor mostly protects lower-paid workers who drive heavily, such as delivery drivers and home health aides. A higher-paid employee could absorb significant vehicle costs without triggering an FLSA violation.

A handful of states require employers to reimburse all necessary business expenses, including mileage, regardless of the employee’s pay. Violations under those state laws can lead to lawsuits for the unreimbursed amount plus penalties. Checking your state’s rules matters more now because employees who pay for business driving out of pocket no longer have a federal tax deduction to fall back on. The Tax Cuts and Jobs Act suspended the miscellaneous itemized deduction for unreimbursed employee expenses starting in 2018, and the One Big Beautiful Bill Act signed in 2025 made that suspension permanent.

If You’re Self-Employed

If you work for yourself as a freelancer, gig worker, or business owner, no one reimburses you. You deduct business miles directly on Schedule C (Form 1040) at the same 72.5-cent rate, and you add parking and tolls on top.⁸

Clients are not required to reimburse independent contractors for mileage. When they do, the payment is generally treated as part of the contractor’s gross income on a 1099, and the contractor offsets it with the mileage deduction on Schedule C. The tax result is roughly the same as an employee receiving tax-free reimbursement under an accountable plan, but the paperwork sits with the contractor.

What the IRS Wants You to Document

Whether you’re seeking reimbursement or claiming a deduction, the IRS expects a written record made at or near the time of each trip. A valid mileage log includes four items for every trip:⁵

The date of the trip.
The destination (city, town, or area).
The business purpose, such as “client meeting” or “site inspection.”
The mileage, either as starting and ending odometer readings or as total miles driven.

The IRS does not require a specific format, only the specific information. A spreadsheet, a dedicated app, or a paper notebook all work. GPS trackers and mapping tools are widely accepted for confirming distances, but you still have to record the business purpose yourself. Log each trip the same day or within a few days. Reconstructing a year of driving from memory at tax time is the kind of estimate auditors routinely reject.

Standard Rate or Actual Expenses

The standard mileage rate is the simpler method: multiply your business miles by 72.5 cents. The alternative is the actual expense method, where you total what you spend on gas, oil, tires, repairs, insurance, registration, and depreciation or lease payments, then multiply by the percentage of miles you drove for business.⁴ The actual expense method sometimes produces a bigger deduction if your vehicle costs are unusually high.

If you own the car, you have to pick the standard mileage rate in the first year the vehicle is available for business use to keep the option of switching between methods later. If you lease the car, you’re locked into whichever method you choose for the entire lease term, including renewals.⁴

Doing the Math

The calculation is straightforward. For an employee who drove 800 business miles in a month at the 2026 rate:

800 × $0.725 = $580.00¹

Add any business parking and toll receipts on top. If the employer runs an accountable plan and pays at or below 72.5 cents per mile, the full $580 is tax-free. Most employers include mileage as a separate non-taxable line item on a regular paycheck or send it as a separate payment on a monthly or biweekly cycle.
