How Much Is Gas Reimbursement Per Mile: Rate, Rules, and Records

Gas reimbursement per mile in 2026 follows the IRS standard business mileage rate of 72.5 cents per mile, up from 70 cents in 2025.¹ That figure is the number most employers use to pay workers who drive personal vehicles for the job, and it’s the same rate self-employed people use to deduct business driving on Schedule C. One thing to know up front: despite the “gas reimbursement” label, the rate isn’t just fuel. It bundles gas, insurance, depreciation, maintenance, and registration into a single per-mile amount, so a check calculated at 72.5 cents is meant to cover the full cost of putting your car on the road for work.

What the 2026 Rate Covers and Who Sets It

The IRS updates the rate each December for the following year. An independent contractor studies fixed and variable vehicle operating costs on the agency’s behalf to arrive at the business figure.¹ Because the number folds every ownership cost together, you don’t need to keep gas receipts to claim it or receive it; miles are the unit that matters.

Parking fees and tolls paid on a business trip are reimbursable or deductible on top of the mileage rate. Parking at your regular workplace is not; the IRS treats that as personal commuting.²

Two other rates exist for different situations. Medical driving and qualifying military moves reimburse at 20.5 cents per mile in 2026, and charitable volunteer driving pays 14 cents per mile.¹ Those aren’t what employers use for on-the-job driving, but they come up on personal tax returns.

Who Can Actually Get Paid or Claim the Rate

The rate exists for everyone, but who benefits from it looks very different depending on how you’re paid.

Self-Employed Drivers

If you work for yourself, you deduct business miles at 72.5 cents on Schedule C. Rideshare drivers, freelancers, sole proprietors, and independent contractors all qualify. The deduction reduces both income tax and self-employment tax, so a mile driven is worth more than the rate suggests once payroll taxes are factored in.

W-2 Employees

Regular employees cannot deduct unreimbursed mileage on their federal returns. The Tax Cuts and Jobs Act suspended that deduction starting in 2018, and Congress made the suspension permanent through Section 70110 of the One Big Beautiful Bill Act.¹ It is not coming back.

A narrow group of employees can still claim mileage as an adjustment to income: Armed Forces reservists, state or local government officials paid on a fee basis, qualified performing artists, employees with impairment-related work expenses, and eligible educators (subject to a dollar cap).³ Everyone else with a W-2 is entirely dependent on the employer to pay them back.

How Employer Reimbursement Works

Since most employees can’t deduct anything, the structure of the employer’s reimbursement plan is what determines whether the money is actually tax-free.

Accountable Plans

Under an accountable plan, reimbursements are tax-free and don’t appear as wages. The plan must meet three requirements: a business connection for the expenses, substantiation with adequate records, and return of any excess reimbursement within a reasonable time.⁴

When an employer pays exactly 72.5 cents per mile through an accountable plan, the full amount is tax-free. If the employer pays more, the portion up to 72.5 cents is tax-free and reported under code L in box 12 of your W-2, while the excess is added to your wages in box 1 and taxed.² An employer paying less than the federal rate is allowed to do so; the employee simply gets less money and has no way to deduct the shortfall.

Nonaccountable Plans

If the plan fails any of the three requirements, the entire reimbursement becomes taxable wages. It shows up in box 1 of the W-2 and is subject to income tax withholding and employment taxes.⁵ The gap is significant. Ten thousand business miles reimbursed at 72.5 cents equals $7,250. Under an accountable plan, that $7,250 lands in your pocket. Under a nonaccountable plan, it lands in your paycheck as taxable income, and there is no offsetting deduction available.

Is Reimbursement Required?

Federal law does not require private employers to reimburse mileage. A few states, including California, Illinois, and Massachusetts, do mandate it. Outside those states, whether you get paid for driving depends on your employer’s policy.

There is one federal backstop under the Fair Labor Standards Act. If unreimbursed vehicle expenses push an employee’s effective pay below the federal minimum wage in any workweek, the employer has violated the law. The Department of Labor has confirmed that when employees must use personal vehicles for the employer’s benefit, those costs cannot eat into minimum wage or overtime pay.⁶

Which Miles Count

Reimbursable business miles include travel between two work locations, trips from a home office to a client site, and drives to temporary work locations. Your “tax home” is generally the city or area where your main place of business is, not necessarily where you live.²

Commuting miles never qualify. Driving from home to your regular workplace is personal, no matter the distance, and taking business calls along the way doesn’t change that.²

There’s one useful exception. If you have a regular workplace and drive to a temporary job site in the same trade or business, that round trip from home is deductible or reimbursable regardless of distance. A location is “temporary” if the assignment is realistically expected to last one year or less. Once it crosses that line, the site becomes your new tax home and the drive becomes personal.²

Records You Need

Whether you’re submitting to an employer or claiming a deduction, the IRS expects contemporaneous records, meaning entries made at or near the time of the trip rather than reconstructed later. Each trip should show:

The date of the trip.
The destination, including the city or address.
The business purpose, such as the client name or meeting topic.
The miles driven.

Also record odometer readings at the start and end of each tax year, and when you begin or stop using a vehicle for business.⁷ A paper notebook is acceptable, but GPS-based tracking apps produce timestamped, location-verified entries that hold up better under scrutiny.

Keep mileage records for at least three years after filing the return that uses them. If you underreport income by more than 25%, the IRS has six years to audit, so hang onto records longer when your finances are complicated.⁸

Running the Numbers

The calculation is one multiplication. Take your qualifying business miles and multiply by 72.5 cents.

A self-employed consultant driving 12,000 business miles in 2026 would claim 12,000 × $0.725 = $8,700 on Schedule C.¹ An employee who submits a log showing 800 miles in a pay period would receive 800 × $0.725 = $580, tax-free under an accountable plan.² Submit the log and the calculation to payroll on your employer’s normal expense-report cycle.
