Our Mileage Reimbursement Calculator helps to determine the compensation of travel while you are on official business. This amount is calculated as a baseline or minimum by IRS to ensure employees are fairly compensated for their travel expenses.

Mileage Reimbursement Basics

If you frequently drive your car for work, you can deduct vehicle expenses on your tax return in one of two ways. The first and most comprehensive method is to document all of your car expenses, including gas, maintenance, insurance, and depreciation. Then deduct the portion of those total costs that apply to your business miles. If that sounds too daunting, you can choose the second method, which allows you to deduct a flat rate for every business mile you drive. That is known as the standard mileage deduction, and the rate varies from year to year.

You can also write off car expenses related to charity work or moving purposes. But, you still must choose between one of the two methods to calculate the deduction.

The table below shows standard mileage deduction rates for business, moving and charitable purposes.

Note that your ability to claim standard deductions for moving or medical expenses may depend on your tax situation.
