Introduction

If you drive your own car for work, medical visits, or charity, you can get money back for each mile you drive. This is called mileage reimbursement. The IRS sets standard mileage rates each year that tell you how much each mile is worth. Our free Mileage Reimbursement Calculator uses these official IRS rates to figure out your total reimbursement.

Just pick your tax year, enter the miles you drove in each category, and the calculator works out your total. It covers business miles, medical and moving miles, and charitable miles, all at the correct per-mile rate. You can also log individual trips, use custom employer rates, and generate a printable report to keep with your records.

This tool helps you find the exact dollar amount you are owed, from business drives to expense reports to volunteer charity miles. It supports IRS mileage rates from 2019 through 2026, so you can calculate reimbursements for past and current tax years.

How to Use Our Mileage Reimbursement Calculator

Enter the miles you drove and the tax year, and this calculator will show you how much money you can get back using IRS standard mileage rates.

Tax Year: Pick the tax year for your trips. The calculator will use the correct IRS mileage rate for that year.

Vehicle Type: Choose the type of vehicle you drove. IRS standard rates are made for cars, SUVs, and pickup trucks. If you pick a different vehicle, you may need to enter a custom rate from your employer.

Business / Work Miles: Type the total miles you drove for work or business purposes.

Medical / Moving Miles: Type the total miles you drove to get medical care or for a qualified military move.

Charitable Miles: Type the total miles you drove while doing volunteer work for a charity.

Trip Date & Time: Pick the date and time of your trip. This only shows up on your report and does not change your total.

Custom Rates: Open this section if your employer gives you a different per-mile rate. Give it a name, type the rate in dollars per mile, and enter how many miles you drove at that rate.

City / Highway Split: Open this section to note how many of your miles were on city streets and how many were on the highway. This is for your records only and does not change the total.

Calculate Distance by Coordinates: Open this section if you want to find the distance between two places. Enter the latitude and longitude of your start point and end point, or click "My location" to use your current spot. You can also add stops along the way. Check "Round trip" if you drove there and back. Pick which mileage category the distance should count toward, then click "Get Distance."

Trip Log Mode: Click the "Trip Log" tab to log each trip one by one. For each trip, type a short description, the date, the miles driven, and pick the IRS category. The rate fills in on its own, but you can change it. Click "Add Trip" to add more rows.

Calculate: Click the "Calculate" button to see your total mileage reimbursement, a breakdown by category, a bar chart, and a step-by-step explanation of the math.

Generate Report: Click "Generate Report" to open a clean, printable page with all your mileage reimbursement details that you can save as a PDF or print.

What Is Mileage Reimbursement?

Mileage reimbursement is money you get back for using your own car for work, medical trips, or charity. When you drive your personal vehicle for these purposes, you can claim a set amount for each mile you drove. This helps cover the cost of gas, oil, tires, and general wear on your car.

How IRS Mileage Rates Work

Each year, the IRS sets standard mileage rates. These rates tell you how much each mile is worth based on the reason you drove. There are three categories:

  • Business / Work: Driving for your job, such as visiting a client or going to a second work site. This rate is the highest. From July 1 to December 31, 2026, it is 76 cents per mile.1
  • Medical / Moving: Driving to a doctor, hospital, or for a qualified military move. From July 1 to December 31, 2026, this rate is 23.5 cents per mile.1
  • Charitable: Driving to do volunteer work for a qualified nonprofit. This rate has been 14 cents per mile in every year the IRS lists, back to 2011.1

How to Calculate Your Reimbursement

The math is simple. Multiply the number of miles you drove by the rate for that category. For example, if you drove 100 miles for work in 2025, you would multiply 100 × $0.70 to get $70.00 in reimbursement. If you drove for more than one reason, you calculate each category separately and then add them together for your total.

Who Can Claim Mileage Reimbursement?

Self-employed workers can deduct business mileage on their tax return and estimate their overall self-employment tax obligation with our Self Employment Tax Calculator. Employees may get reimbursed directly by their employer, but most cannot deduct unreimbursed car costs on their federal return, because that miscellaneous itemized deduction is no longer allowable.2 Driving for charity or medical care may still be deductible for people who qualify.1

Tips for Tracking Your Miles

The IRS requires records to prove car expenses.2 For each business use, write down the date, your destination, the business purpose, and the miles driven, and keep your total miles for the year.2 Keep this log all year long. Good records make filing taxes easier and protect you if the IRS ever asks for proof, and our Mileage Calculator can help you track and verify total miles between locations.

Frequently asked questions

Can I use a custom rate from my employer instead of the IRS rate?

Yes. Open the Use Custom Rates section, type your employer's rate in dollars per mile, and enter the miles you drove at that rate. The calculator adds the custom amount to your grand total.

Does the City / Highway split change my total reimbursement?

No. The City / Highway split is for your records only. It shows how your miles break down by road type, but it does not change the dollar amount you are owed.

Is the coordinate distance an exact driving distance?

No. It is a straight-line estimate based on GPS coordinates. Actual road distance may be longer because roads curve and follow streets. Use it as a quick estimate, and adjust the miles if needed.

Why does the rate change when I pick a different tax year?

The IRS updates its standard mileage rates each year based on driving costs like gas, insurance, and car wear. When you pick a different year, the calculator loads that year's official rates so your total is correct.

What is the 2026 IRS mileage rate for business driving?

For 2026 the IRS business rate is 72.5 cents per mile from January 1 to June 30 and 76 cents per mile from July 1 to December 31.1 Pick the matching half of 2026 in the Tax Year list.

Can employees still deduct mileage on their taxes?

Most employees cannot deduct unreimbursed mileage on their federal tax return, because that miscellaneous itemized deduction is no longer allowable.2 However, your employer can still reimburse you directly. Self-employed workers can still claim the deduction.

Does the trip date and time affect my reimbursement total?

No. The trip date and time are only used on the printed report. They help you keep good records but do not change the calculated amount.

Can I calculate mileage reimbursement for past tax years?

Yes. Select any year from 2019 to 2026 in the Tax Year dropdown. The calculator will use the IRS rates that were in effect for that year, with 2022 and 2026 split into their two half-year periods.

What records should I keep for mileage reimbursement?

For each trip, record the date, destination, business purpose, and miles driven, plus your total miles for the year.2 You need these records to prove car expenses if the IRS asks, and employers that reimburse under an accountable plan may require them too.2 The Trip Log and Generate Report features help you create this record.
