Mileage Deduction Calculator
Self-employed? Track your business miles and deduct them at the IRS standard rate. This calculator applies the 2026 rate to any mileage — instantly.
How this calculator works
The IRS sets a per-mile rate that covers gas, oil, repairs, insurance, and depreciation — so you cannot deduct those costs separately on top of it. The 2026 business rate is 76¢ per mile from July 1, 2026 (it was 72.5¢ from January through June; split your miles if they span both periods). The calculator multiplies your miles by the rate you enter.
Frequently asked questions
What counts as business mileage?
Miles driven for work-related travel — client visits, errands for your business, travel to a second job or temporary work site. Commuting between home and your regular workplace does not count, though the 2026 rules keep the commuting deduction for certain trades like electricians and construction workers.
Standard mileage or actual expenses?
Standard mileage is simpler: one rate, no receipts beyond a mileage log. Actual expenses (gas, repairs, insurance, depreciation allocated by business use) can be larger for expensive or heavily driven vehicles. Once you choose standard mileage in the first year you own the car, you can switch to actual later — but not the other way around.
What is the 2026 medical mileage rate?
23.5¢ per mile for medical and moving purposes (down a half cent from the start of the year). Medical miles are deductible as part of itemized medical expenses above 7.5% of AGI — keep the log whether you use the standard or actual method.
