SECTION 4. DEFINITIONS

.01 Standard mileage rate . The term “standard mileage rate” means the applicable amount provided by the Service for optional use by employees or self-employed individuals in computing the deductible costs of operating automobiles (including vans, pickups, or panel trucks) they own or lease for business purposes, or by taxpayers in computing the deductible costs of operating automobiles for charitable, medical, or moving expense purposes.

.02 Transportation expenses . The term “transportation expenses” means the expenses of operating an automobile for local travel or transportation away from home.

.03 Mileage allowance . The term “mileage allowance” means a payment under a reimbursement or other expense allowance arrangement that meets the requirements specified in § 1.62–2(c)(1) and that is:

(1) paid with respect to the ordinary and necessary business expenses incurred, or that the payor reasonably anticipates will be incurred, by an employee for transportation expenses in connection with the performance of services as an employee of the employer,

(2) reasonably calculated not to exceed the amount of the expenses or the anticipated expenses, and

(3) paid at the applicable standard mileage rate, a flat rate or stated schedule, or in accordance with any other Service-specified rate or schedule.

.04 Flat rate or stated schedule . A mileage allowance is paid at a flat rate or stated schedule if it is provided on a uniform and objective basis with respect to the expenses described in section 4.03 of this revenue procedure. The allowance may be paid periodically at a fixed rate, at a cents-per-mile rate, at a variable rate based on a stated schedule, at a rate that combines any of these rates, or on any other basis that is consistently applied and in accordance with reasonable business practice. Thus, for example, a periodic payment at a fixed rate to cover the fixed costs (including depreciation (or lease payments), insurance, registration and license fees, and personal property taxes) of driving an automobile in connection with the performance of services as an employee of the employer, coupled with a periodic payment at a cents-per-mile rate to cover the operating costs (including gasoline and all taxes thereon, oil, tires, and routine maintenance and repairs) of using an automobile for those purposes, is an allowance paid at a flat rate or stated schedule. Likewise, a periodic payment at a variable rate based on a stated schedule for different locales to cover the costs of driving an automobile in connection with the performance of services as an employee is an allowance paid at a flat rate or stated schedule.
