The Internal Revenue Service (IRS) mileage rate is a standard rate set by the U.S. government for reimbursing automobile expenses incurred while conducting official business. The rate is adjusted annually to reflect changes in the cost of fuel, maintenance, and depreciation. For 2025, the IRS mileage rate is 65.5 cents per mile.
The IRS mileage rate is important because it provides a consistent and fair method for reimbursing employees for their automobile expenses. It is also used by businesses to calculate deductible expenses for tax purposes. The rate is based on a study of the fixed and variable costs of operating an automobile, and it is updated annually to reflect changes in these costs.
