Standard-mileage deduction
-
Show the math
The standard mileage method multiplies miles by the IRS rate:
deduction = miles × rate per mile
Uses the 2026 IRS standard mileage rates, which changed mid-year. From July 1 – December 31, 2026: business 76¢, medical & moving 23.5¢, charity 14¢ per mile. From January 1 – June 30, 2026: business 72.5¢, medical & moving 20.5¢, charity 14¢. If you drove in both periods, total each period separately. Business and medical mileage need a log; the actual-expense method may give a larger deduction. Estimate only, not tax advice. All math runs locally in your browser.
What this does
A mileage deduction calculator works out your standard-mileage tax deduction for business, medical, moving, or charitable driving using the current IRS rates.
How it works
Each category has its own per-mile rate. Multiplying your qualifying miles by that rate gives the deduction. The standard rate bundles fuel, repairs, and depreciation into one figure.
Deduction = miles × IRS rate
How to use it
- Choose the driving category.
- Enter your qualifying miles.
- Read your standard-mileage deduction.
- Keep a contemporaneous mileage log.
Understanding your result
The standard rate is simplest, but tracking actual costs sometimes yields a larger deduction, you generally choose one method. The IRS requires a log of dates, miles, and purpose.
Example
At the July–December 2026 business rate of 76¢, 5,000 business miles is a $3,800 deduction.
