Mileage reimbursement calculator
The IRS sets standard mileage rates that employers use to reimburse driving and that self-employed people use to deduct it.
In 2026 the IRS raised the business and medical rates from July 1 because of fuel prices, so the date of your trips matters.
How it's calculated
- Pick the purpose and the date of the trips to get the right rate.
- Business miles are worth $0.76 each today. Medical and military moving miles are worth $0.235. Charity miles are worth $0.14, a rate fixed by law.
- Multiply the miles by the rate.
An example
1,000 business miles driven in March 2026 are worth $725. The same miles driven in August 2026 are worth $760.
Frequently asked questions
What is the IRS mileage rate for 2026?
Since July 1, 2026 it is $0.76 per business mile and $0.235 per medical or moving mile. Both rates were lower in the first half of the year. Charity stays at $0.14.
Does my employer have to pay the IRS rate?
Federal law doesn't require it. Many employers use it anyway because reimbursements up to that rate under an accountable plan aren't taxed. A few states have their own reimbursement rules.
Can I deduct commuting miles?
No. Driving between your home and your regular workplace is personal commuting, not business travel.
