Understanding the 2023 Federal Mileage Reimbursement Rates
The Federal Mileage Reimbursement Rate 2023 Calculator is designed to help employees, self-employed individuals, and business owners calculate the deductible value of vehicle use for the 2023 tax year. The Internal Revenue Service (IRS) sets these standard mileage rates annually to simplify the calculation of automobile expenses for business, charitable, medical, or moving purposes.
Official IRS Rates for 2023
For the calendar year 2023 (effective January 1, 2023), the IRS issued Notice 2023-03 detailing the optional standard mileage rates. These rates increased from 2022 due to rising fuel and maintenance costs.

How to Use This Calculator
Calculating your reimbursement or tax deduction is straightforward using the tool above:
Enter Miles Driven: Input the total number of miles driven specifically for the qualified purpose. Do not include personal commuting miles (driving from home to your regular place of work), as these are generally not deductible.
Select Deduction Type: Choose the category that fits your trip. The Business rate is the highest as it accounts for fuel, insurance, wear and tear, and depreciation. The Medical rate covers variable costs like gas and oil.
Review the Result: The calculator multiplies your miles by the 2023 mandated rate to provide the total deductible amount or expected reimbursement.
Important Rules for Mileage Reimbursement
To claim these rates on your taxes or receive reimbursement from an employer, you must adhere to strict record-keeping guidelines:
Logbook: Maintain a timely log containing the date, mileage, destination, and business purpose of every trip.
Odometer Readings: It is recommended to record the starting and ending odometer readings for the year.
Standard Rate vs. Actual Expenses: You generally have the choice to use the standard mileage rate (calculated above) or deduct actual vehicle expenses (gas, insurance, repairs). However, if you choose the standard mileage rate, you must usually choose it in the first year the car is available for business use.
Note: This calculator uses the rates specifically for the 2023 tax year. If you are calculating mileage for a different year, please ensure you use the specific rates assigned by the IRS for that period, as they fluctuate based on economic conditions.
