Standard mileage rate vs. actual vehicle expenses
Taxpayers have two choices for deducting vehicle costs: the standard mileage rate or actual expenses (gas, oil, repairs, insurance, registration, depreciation, and lease payments). The standard mileage rate is easier because it replaces individual receipts with a single per-mile multiplier published annually by the IRS.
For 2025, the business mileage rate is 70 cents per mile (IRS Notice 2024-84), up from 67 cents in 2024 (Notice 2024-08). Medical and military moving rates remain 21 cents per mile, while charitable volunteer travel is set by federal statute at 14 cents per mile. To use the standard rate for a personal car you own, you must choose it in the first year the car is available for business use.
