Frequently asked questions
Why did the rate change mid-year in 2026?
The IRS increased the business standard mileage rate from 72.5¢ to 76¢ per mile effective July 1, 2026, citing rising vehicle costs — use whichever period matches when the trip actually happened.
What about medical, moving, or charitable mileage?
Those use different rates that this calculator doesn't preset (to avoid showing an unverified number) — use the custom rate option with your own figure for those purposes.
