2026 IRS Mileage Rates
The IRS updated its standard mileage rates effective January 1, 2026. The business rate increased to 72.5 cents per mile, up from 70 cents in 2025. This rate covers all costs of operating your vehicle for business, including gas, insurance, maintenance, depreciation, and registration fees. You cannot claim these expenses separately if you use the standard mileage rate.
The medical and moving rate dropped slightly to 20.5 cents per mile. The charitable rate stays at 14 cents per mile, which is set by Congress and has not changed since 1998. The rates for 2026 are published in IRS Notice 2026-10.
How to Track Your Miles
The IRS requires what they call "contemporaneous records," meaning you need to log your miles at or near the time you drive them. A mileage log should include the date, starting location, destination, business purpose, and total miles for each trip. You can use a notebook in your car, a spreadsheet, or a mileage tracking app.
You do not need to keep gas receipts or repair bills when using the standard mileage rate. The rate already covers those costs. However, you do need to track your actual miles driven and be able to show that each trip had a legitimate business purpose if the IRS asks.
At the end of the year, add up all your qualifying business miles and multiply by the rate. That total is your deduction or the basis for your employer reimbursement. If your employer reimburses you at the IRS rate, the reimbursement is not taxable income.
