SECTION 3. BACKGROUND AND

CHANGES

.01 Section 162(a) of the Internal Revenue Code allows a deduction for all the ordinary and necessary expenses paid or incurred during the taxable year in carrying on any trade or business. Under that provision, an employee or self-employed individual may deduct the cost of operating an automobile to the extent that it is used in a trade or business. However, under § 262, no portion of the cost of operating an automobile that is attributable to personal use is deductible.

.02 Section 274(d) provides, in part, that no deduction shall be allowed under § 162 with respect to any listed property (as defined in § 280F(d)(4) to include passenger automobiles and any other property used as a means of transportation) unless the taxpayer complies with certain substantiation requirements. The section further provides that regulations may prescribe that some or all of the substantiation requirements do not apply to an expense that does not exceed an amount prescribed by such regulations.

.03 Section 1.274(d)–1T, in part, grants the Commissioner the authority to prescribe rules relating to mileage allowances for ordinary and necessary expenses of local travel and transportation away from home. Pursuant to this grant of authority, the Commissioner may prescribe rules under which such allowances, if in accordance with reasonable business practice, will be regarded as (1) equivalent to substantiation, by adequate records or other sufficient evidence, of the amount of such travel and transportation

(1) paid with respect to the ordinary and necessary business expenses incurred, or which 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 Servicespecified 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. Such 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 such 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.
