Mileage Calculator
Calculate mileage reimbursement at standard IRS or custom rates.
About Mileage Calculator
The IRS publishes standard mileage rates each year for business, medical/moving, and charitable driving. Taxpayers using the standard rate cannot also deduct actual vehicle expenses. The charity rate of $0.14/mile is set by statute (26 U.S.C. § 170(i)) and is fixed in every year. Rates for the selected tax year are shown; for 2026 a mid-year rate increase applies — see the FAQ.

Assumptions and limits
- The result is derived only from the 6 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation or fees or charges into account.
- Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
What are the IRS mileage rates for each year?
2024: business $0.67/mi, medical $0.21/mi, charity $0.14/mi. 2025: business $0.70/mi, medical $0.21/mi, charity $0.14/mi. 2026: business $0.725/mi (Jan–Jun) or $0.76/mi (Jul–Dec), medical $0.205/mi or $0.235/mi, charity $0.14/mi. Always verify at IRS.gov before filing.
Why are there two different rates for 2026?
The IRS issued a mid-year rate increase effective July 1, 2026, raising the business rate from 72.5¢ to 76¢ per mile (and medical from 20.5¢ to 23.5¢). Miles driven before July 1 use the lower rate; miles on or after July 1 use the higher rate. The Travel Period field appears when you select 2026 so you can pick the correct rate. If you drove in both halves of 2026, run the calculator twice and add the results.
Should I use the standard mileage rate or actual expenses?
If your vehicle gets reasonably good mileage and you drive a lot for business, the standard rate is usually simpler and sometimes more advantageous. If you drive a high-cost vehicle with high actual expenses, tracking actual costs may yield a larger deduction. You cannot switch methods within the same vehicle's life once you choose actual.
Do I need a mileage log?
Yes. The IRS requires contemporaneous records: date, destination, business purpose, and miles for each trip. Apps like MileIQ or a simple spreadsheet satisfy this requirement.
Are mileage reimbursements taxable?
Employer reimbursements at or below the IRS standard rate are excluded from taxable income (accountable plan rules). Reimbursements above the standard rate, or under a non-accountable plan, are taxable wages.
Which tax year does this use?
You can select 2024, 2025, or 2026 from the Tax Year field at the top. The calculator uses that year's IRS-published rates. For 2026, a period selector also appears because rates changed mid-year.
