How the mileage deduction works
Every business mile you drive in 2026 is worth 72.5 cents as a deduction against your self-employment profit. Instead of saving every gas receipt and repair bill, the IRS lets you multiply your business miles by one flat rate. Drive 8,000 business miles and the math is 8,000 × $0.725 = $5,800 off your taxable profit. For a typical rideshare or delivery driver, that single line item often beats every other deduction combined.
The standard rate is a stand-in for the real costs of running the car: gas, oil, maintenance, insurance, registration, and depreciation. The alternative is the actual expense method, deducting the business-use share of what the car truly cost you. Actual expenses can win for newer or pricier vehicles, but it demands every receipt plus a depreciation calculation, and there’s a catch: to keep the standard rate as an option for a car you own, you must choose it in the first year you use that car for business.
None of it survives an audit without records. The IRS expects a contemporaneous log showing the date, miles, destination, and business purpose of each trip. A tracking app or a weekly spreadsheet works; a year-end reconstruction doesn’t. Our mileage log guide covers exactly what to record and which shortcuts the IRS accepts.
Mileage is one piece of the picture. To see what you actually keep after platform fees, vehicle costs, and taxes, run your numbers through the gig earnings calculator.
These are estimates, not tax advice. The savings figure is an approximation that combines self-employment tax with your selected marginal bracket; it does not model bracket boundaries crossed mid-deduction or state income tax, which would add to the savings in most states.
Where these numbers come from
The deduction is business miles multiplied by the IRS standard mileage rate, plus parking and tolls. The savings estimate applies the effective SE-tax rate plus your selected marginal bracket. Every figure is transcribed from these sources:
- IRS Newsroom, 2026 standard mileage rate: 72.5 cents per business mile for 2026, Notice 2026-10
- IRS Publication 463, Travel, Gift, and Car Expenses: substantiation rules: what a mileage log must contain
Constants last verified against these sources on June 11, 2026. Every value is also pinned by an automated test suite that fails if a rate in the calculator drifts from the figure we transcribed from the source.
