Short answer
Use this page when you need a fast IRS-based mileage reimbursement estimate for 2023. It covers business, self-employed business, medical, moving, and charitable mileage so you can choose the right category before multiplying miles by the rate.
At a glance
- The 2023 IRS business rate is 65.5 cents per mi.
- The 2023 medical and moving rate is 22.0 cents per mi, and both categories use the same published IRS amount.
- The 2023 charitable rate remains 14.0 cents per mi.
Current 2023 IRS mileage categories
Business and self-employed business
65.5 cents per mi for ordinary business travel. This is the rate most employers benchmark when they reimburse employees for using a personal car on work trips.
Medical and moving
22.0 cents per mi for qualified medical travel and 22.0 cents per mi for eligible active-duty moving travel. The calculator keeps this separate because the IRS rate is much lower than the business category. See our medical mileage guide for details on the 7.5% AGI floor.
Charitable
14.0 cents per mi for mileage tied to qualified charitable service. This rate is set by statute and has not changed since 1998. See our charitable mileage article for why.

Common questions
Is this page for reimbursement or deduction estimates?
Both. The IRS mileage categories are the same rate inputs, but the workflow differs. Employers usually use the business category for reimbursement planning, while self-employed taxpayers use the same business rate for deduction estimates.
Does this calculator use the latest IRS rate for 2023?
Yes. The default year uses the 2023 IRS rates stored in the rate catalog, and the result block links back to the underlying IRS source used for the estimate.
Are gas, maintenance, and insurance added separately?
Not in the standard mileage method. The IRS mileage rate is meant to stand in for the ordinary costs of operating the vehicle. Parking and tolls can still be tracked separately when the underlying rule allows them.
Which trips should not be entered here?
Do not enter ordinary commuting. This page is for business, qualified medical, charitable, or eligible moving mileage only. If the trip is not in one of those buckets, the estimate will not match the IRS rule you actually need.
What should I do after I get the estimate?
Keep the trip records, confirm the rate year and category, and move into a mileage log or reimbursement form workflow if the estimate is going to support payroll, expense approval, or tax records.
