2026 business mileage reimbursement
Mileage reimbursement in 2026: 76¢ IRS business rate from July 1
The current IRS business mileage rate is 76¢ per mile. It was 72.5¢ through June 30. Employers can use the IRS rate as a reimbursement benchmark, but it is not a blanket federal mandate to pay that exact amount.
Quick answer
Two IRS business mileage rates apply in 2026
The midyear change matters when a reimbursement policy uses the IRS standard mileage rate. Keep the trip date attached to every business mile so the correct period can be applied.
Important: the IRS rate is a tax benchmark. An employer may reimburse at a different rate, while state law or company policy may impose separate requirements.
Is 76¢ per mile the required employer reimbursement rate?
Not as a general federal rule. The IRS standard mileage rate is an optional federal rate used to calculate deductible vehicle costs and, under qualifying reimbursement arrangements, the amount of a mileage allowance treated as substantiated. Employers can set a different mileage reimbursement policy.
That means two questions should be kept separate:
Tax benchmark
What rate does the IRS publish?
76¢ per business mile from July 1 through Dec. 31, 2026, after 72.5¢ in the first half of the year.
Employer obligation
What must my employer reimburse?
That depends on the employer's policy and any applicable state expense-reimbursement rules. The IRS rate itself is not a universal federal reimbursement requirement.
How mileage reimbursement works under an accountable plan
IRS accountable-plan rules are designed to separate legitimate business expense reimbursement from taxable wages. The arrangement must have a business connection, the employee must adequately account for the expense within a reasonable period, and any excess reimbursement must be returned within a reasonable period.

IRS Publication 463 says the exact meaning of a “reasonable period” depends on the circumstances. It also provides safe-harbor timing: adequately accounting within 60 days after an expense and returning excess reimbursement within 120 days are treated as reasonable.
What should a mileage reimbursement record include?
A strong mileage claim is built from individual trips, not just a monthly odometer total. Publication 463 says car-expense records should support the date, business destination, business purpose and mileage for each business use.

What if an employer pays more or less than the IRS rate?
An employer can reimburse below the federal rate, at the federal rate, or above it. Under an accountable plan, mileage allowances up to the federal rate can generally be excluded from wages when the employee adequately accounts for the business travel. Amounts above the federal rate can become taxable wages unless handled under the applicable rules.
For employees, reimbursement and personal tax deduction are also different issues. Most employees cannot simply deduct unreimbursed business mileage on their federal return; limited exceptions apply. Self-employed taxpayers follow different deduction rules.
Why automatic Tesla trip capture helps
The reimbursement formula is easy. Reconstructing the underlying trips at month-end is not. DriveQuery is designed to capture Tesla journeys automatically, preserve the trip date and mileage, remember user-defined places, and surface the trips that still need a business/personal decision.
Vehicle data does not determine tax eligibility. DriveQuery can capture trip facts, but the driver or business still needs to confirm the business purpose and whether a trip qualifies under its policy and applicable rules.

Does an employer have to reimburse mileage at the IRS rate?
No general federal rule requires every employer to reimburse at the exact IRS rate. The IRS rate is a federal tax benchmark. Employer policy and applicable state law can create different reimbursement obligations.
What is an accountable plan for mileage reimbursement?
Under IRS rules, an accountable plan requires a business connection, adequate accounting within a reasonable period, and return of any excess reimbursement or allowance within a reasonable period.
How soon should employees submit mileage records?
The facts and circumstances control, but IRS Publication 463 treats accounting within 60 days after the expense and returning excess reimbursement within 120 days as occurring within a reasonable period.
What should a business mileage reimbursement record include?
Records should support the date, business destination, business purpose and mileage for each business use. Trip-level records are much stronger than trying to recreate a month from one odometer total.
Can Tesla trip data replace the business purpose?
No. Tesla vehicle data can capture facts such as mileage and route context, but the driver or business still needs to identify why the trip was business-related.
The reimbursement rate is one line. The trip record behind it is the real work.
DriveQuery captures Tesla journeys automatically so business mileage can be reviewed while the purpose is still fresh.
