How Mileage Reimbursement Works
Mileage reimbursement compensates employees for using personal vehicles for business travel. The reimbursement is calculated by multiplying the miles driven by the per-mile rate. The IRS sets a standard rate that covers gas, maintenance, insurance, and depreciation.
IRS Standard Mileage Rates
The IRS updates the standard mileage rate annually. For 2024, the business rate is 67 cents per mile. Medical and moving (military only) is 21 cents per mile. Charitable driving is 14 cents per mile (set by statute).
Standard Mileage Rate vs Actual Expenses
You can deduct either the standard mileage rate or your actual vehicle expenses (gas, oil, repairs, insurance, depreciation, registration). Track both and use whichever method gives you the larger deduction. Once you choose actual expenses for a vehicle, you generally cannot switch back.
Record Keeping Requirements
The IRS requires a written log of each trip including the date, destination, business purpose, and miles driven. Apps like MileIQ can automate tracking. Keep records for at least three years in case of an audit.
