SEC. 3. BACKGROUND

.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 a passenger automobile to the extent that it is used in a trade or business. However, under § 262, no portion of the cost of operating a passenger 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)–1 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 expenses for purposes of § 1.274–5T(c), and (2) satisfying the requirements of an adequate accounting to the employer of the amount of such expenses for purposes of § 1.274–5T(f).

.04 Section 62(a)(2)(A) allows an employee, in determining adjusted

gross income, a deduction for the expenses allowed by Part VI (§ 161 and following), subchapter B, chapter 1 of the Code, paid or incurred by the employee in connection with the performance of services as an employee under a reimbursement or other expense allowance arrangement with a payor.

.05 Section 62(c) provides that an arrangement will not be treated as a reimbursement or other expense allowance arrangement for purposes of § 62(a)(2)(A) if it—

(1) does not require the employee to substantiate the expenses covered by the arrangement to the payor, or

(2) provides the employee with the right to retain any amount in excess of the substantiated expenses covered under the arrangement. Section 62(c) further provides that the substantiation requirements described therein shall not apply to any expense to the extent that, under the grant of regulatory authority prescribed in § 274(d), the Commissioner has provided that substantiation is not required for such expense.

.06 Under § 1.62–2(c)(1) a reimbursement or other expense allowance arrangement satisfies the requirements of § 62(c) if it meets the requirements of business connection, substantiation, and returning amounts in excess of expenses as specified in the regulations. Section 1.62–2(e)(2) specifically provides that substantiation of certain business expenses in accordance with rules prescribed under the authority of § 1.274(d)–1 will be treated as substantiation of the amount of such expenses for purposes of § 1.62–2. Under § 1.62–2(f)(2), the Commissioner may prescribe rules under which an arrangement providing mileage allowances will be treated as satisfying the requirement of returning amounts in excess of expenses, even though the arrangement does not require the employee to return the portion of such an allowance that relates to miles of travel substantiated and that exceeds the amount of the employee’s expenses deemed substantiated pursuant to rules prescribed under § 274(d), provided the allowance is reasonably calculated not to exceed the amount of the employee’s expenses or anticipated expenses and the employee is required to return any portion of such an allowance that relates to miles of travel not substantiated.

.07 Section 1.62–2(h)(2)(i)(B) provides that if a payor pays a mileage

(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. Such allowance may be paid periodically at a fixed rate, at a cents-permile 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, 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.
