IRS Mileage Reimbursement Calculator

This IRS Mileage Reimbursement Calculator helps you accurately determine the deductible value of your business, medical, or charitable driving for the 2026 tax year. Understanding your eligible mileage deductions is crucial for minimizing your tax liability and ensuring you're properly compensated for work-related expenses. Our calculator incorporates the specific 2026 IRS standard mileage rates, which are projected to be $0.69 per mile for business, $0.23 per mile for medical and moving, and $0.16 per mile for charity.

The calculation methodology is straightforward: the total miles driven for a specific category are multiplied by the corresponding 2026 IRS standard mileage rate. For instance, if you input 100 business miles, the calculator will apply the 2026 business rate of $0.69/mile to arrive at your reimbursement. This method simplifies record-keeping as it accounts for average costs of fuel, maintenance, insurance, and depreciation without requiring detailed expense tracking.

Remember to maintain meticulous records of your mileage, including dates, destinations, and the purpose of each trip, as the IRS may request documentation. A common mistake is to include personal errands or commuting mileage as deductible business expenses, which is not permitted. Also, be aware that you cannot claim both actual expenses and the standard mileage rate for the same vehicle in the same year if you started with the standard mileage rate.
