SECTION 5. BUSINESS STANDARD

MILEAGE RATE

.01 In general . The standard mileage rate for transportation expenses is 48.5 cents per mile for all miles of use for business purposes.

.02 Use of the business standard mileage rate . A taxpayer may use the business standard mileage rate with respect to an automobile that is either owned or leased by the taxpayer. A taxpayer generally may deduct an amount equal to either the business standard mileage rate times the number of business miles traveled or the actual costs (both fixed and variable) paid or incurred by the taxpayer that are allocable to traveling those business miles.

.03 Business standard mileage rate in lieu of fixed and variable costs . A deduction using the business standard mileage rate is computed on a yearly basis and is in lieu of all fixed and variable costs of the automobile allocable to business purposes (except as provided in section 9.06 of this revenue procedure). Items such as depre

proximating the actual expenses employees receiving the allowance would incur as owners of the standard automobile.

.02 Computation of FAVR allowance . (1) FAVR allowance . A FAVR allowance includes periodic fixed payments and periodic variable payments. A payor may maintain more than one FAVR allowance. A FAVR allowance that uses the same payor, standard automobile (or an automobile of the same make and model that is comparably equipped), retention period, and business use percentage is considered one FAVR allowance, even though other features of the allowance may vary. A FAVR allowance also includes any optional high mileage payments; however, optional high mileage payments are included in the employee’s gross income, are reported as wages or other compensation on the employee’s Form W–2, and are subject to withholding and payment of employment taxes when paid. See section 9.05 of this revenue procedure. An optional high mileage payment covers the additional depreciation for a standard automobile attributable to business miles driven and substantiated by the employee for a calendar year in excess of the annual business mileage for that year. If an employee is covered by the FAVR allowance for less than the entire calendar year, the annual business mileage may be prorated on a monthly basis for purposes of the preceding sentence.

(2) Periodic fixed payment . A periodic fixed payment covers the projected fixed costs (including depreciation (or lease payments), insurance, registration and license fees, and personal property taxes) of driving the standard automobile in connection with the performance of services as an employee of the employer in a base locality, and must be paid at least quarterly. A periodic fixed payment may be computed by (a) dividing the total projected fixed costs of the standard automobile for all years of the retention period, determined at the beginning of the retention period, by the number of periodic fixed payments in the retention period, and (b) multiplying the resulting amount by the business use percentage.

(3) Periodic variable payment . A periodic variable payment covers the projected variable costs (including gasoline and all taxes thereon, oil, tires, and routine maintenance and repairs) of driving a standard

business expenses of an automobile leased by a taxpayer unless the taxpayer uses either the business standard mileage rate or a fixed and variable rate allowance (FAVR allowance) (as provided in section 8 of this revenue procedure) to compute the deductible business expenses of the automobile for the entire lease period (including renewals). For a lease commencing on or before December 31, 1997, the “entire lease period” means the portion of the lease period (including renewals) remaining after that date.

(3) The business standard mileage rate may not be used to compute the deductible expenses of an automobile for which the taxpayer has (a) claimed depreciation using a method other than straight-line for its estimated useful life, (b) claimed a § 179 deduction, (c) claimed the special depreciation allowance under § 168(k), or (d) used the Accelerated Cost Recovery System (ACRS) under former § 168 or the Modified Accelerated Cost Recovery System (MACRS) under current § 168. By using the business standard mileage rate, the taxpayer has elected to exclude the automobile (if owned) from MACRS pursuant to § 168(f)(1). If, after using the business standard mileage rate, the taxpayer uses actual costs, the taxpayer must use straight-line depreciation for the automobile’s remaining estimated useful life (subject to the applicable depreciation deduction limitations under § 280F).

(4) The business standard mileage rate and this revenue procedure may not be used to compute the amount of the deductible automobile expenses of an employee of the United States Postal Service incurred in performing services involving the collection and delivery of mail on a rural route if the employee receives qualified reimbursements (as defined in § 162(o)) for the expenses. See § 162(o) for the rules that apply to these qualified reimbursements.
