Understanding Standard Mileage Reimbursement
Rather than tracking every gas receipt and repair bill, many tax authorities let taxpayers and employers use a flat "standard mileage rate" per mile driven for qualifying purposes. Multiplying miles driven by the applicable rate gives a simple, defensible reimbursement or deduction amount.
Business Mileage
The business rate is typically the highest, since it's meant to cover gas, maintenance, insurance, and depreciation on top of fuel alone.
Medical, Moving & Charitable
These purposes typically use a lower rate that reflects only variable operating costs like fuel and oil, not full vehicle ownership costs.
Standard Rate vs. Actual Expenses
Taxpayers generally have the option to deduct actual vehicle expenses (a portion of gas, insurance, repairs, and depreciation) instead of the standard rate. The standard rate is simpler and requires far less recordkeeping — just a mileage log — but may not always yield the largest deduction.
Keep a Mileage Log
Record the date, purpose, starting/ending odometer readings, and total miles for every trip you plan to claim.
Key Takeaways
