SECTION 9. APPLICATION

.01 If a payor pays a mileage allowance in lieu of reimbursing actual transportation expenses incurred or to be incurred by an employee, the amount of the expenses that is deemed substantiated to the payor is either:

(1) for any mileage allowance other than a FAVR allowance, the lesser of the

.04 An employee is not required to include in gross income the portion of a mileage allowance received from a payor that is less than or equal to the amount deemed substantiated under section 9.01 of this revenue procedure, provided the employee substantiates in accordance with section 9.02. See § 1.274–5(f)(2)(i). In addition, such portion of the allowance is treated as paid under an accountable plan, is not reported as wages or other compensation on the employee’s Form W-2, and is exempt from the withholding and payment of employment taxes. See §§ 1.62–2(c)(2) and (c)(4).

stantiates in accordance with section 9.02 of this revenue procedure. See § 1.274– 5(f)(2)(ii). In addition, the excess portion of the allowance is treated as paid under a nonaccountable plan, is reported as wages or other compensation on the employee’s Form W-2, and is subject to withholding and payment of employment taxes. See §§ 1.62–2(c)(3)(ii), (c)(5), and (h)(2)(i)(B).

which the advance was paid are substantiated. See § 1.62–2(h)(2)(i)(B)(3). If some or all of the business miles with respect to which the advance was paid are not substantiated within a reasonable period of time and the employee does not return the portion of the allowance that relates to those miles within a reasonable period of time, the portion of the allowance that relates to those miles is subject to withholding and payment of employment taxes no later than the first payroll period following the end of the reasonable period. See § 1.62–2(h)(2)(i)(A).

(3) In the case of a mileage allowance that is not computed on the basis of a fixed amount per mile of travel ( e.g., a mileage allowance that combines periodic fixed and variable rate payments, but that does not satisfy the requirements of section 8 of this revenue procedure), the payor must compute periodically (no less frequently than quarterly) the amount, if any, that exceeds the amount deemed substantiated under section 9.01(1) of this revenue procedure by comparing the total mileage allowance paid for the period to the applicable standard mileage rate in section 5.01 of this revenue procedure multiplied by the number of business miles substantiated by the employee for the period. Any excess is subject to withholding and payment of employment taxes no later than the first payroll period following the payroll period in which the excess is computed. See § 1.62–2(h)(2)(i)(B)(4).

(4) For example, assume an employer pays its employees a mileage allowance at a rate of 40 cents per mile (when the business standard mileage rate is 34.5 cents per mile). The employer does not require the return of the portion of the allowance that exceeds the business standard mileage rate for the business miles substantiated (5.5 cents). In June, the employer advances an employee $200 for 500 miles to be traveled during the month. In July, the employee substantiates to the employer 400 business miles traveled in June and returns $40 to the employer for the 100 business miles not traveled. The amount deemed substantiated for the 400 miles traveled is $138 and the employee is not required to return the remaining $22. No later than the first payroll period following the payroll period in which the 400 business miles traveled are substantiated, the employer must

(1) Except as otherwise provided in section 9.06(2) of this revenue procedure with respect to leased automobiles, if the amount of the expenses deemed substantiated under the rules provided in section 9.01 of this revenue procedure is less than the amount of the employee’s business transportation expenses, the employee may claim an itemized deduction for the amount by which the business transportation expenses exceed the amount that is deemed substantiated, provided the employee substantiates all the business transportation expenses, includes on Form 2106, Employee Business Expenses, the deemed substantiated portion of the mileage allowance received from the payor, and includes in gross income the portion (if any) of the mileage allowance received from the payor that exceeds the amount deemed substantiated. See § 1.274–5(f)(2)(iii). However, for purposes of claiming this itemized deduction, substantiation of the amount of the expenses is not required if the employee is claiming a deduction that is equal to or less than the applicable standard mileage rate multiplied by the number of business miles substantiated by the employee minus the amount deemed substantiated under section 9.01 of this revenue procedure. The itemized deduction is subject to the 2-percent floor on miscellaneous itemized deductions provided in § 67.

ated under section 9.01(2) of this revenue procedure (relating to a FAVR allowance) may not claim a deduction based on actual expenses.

.07 An employee may deduct an amount computed pursuant to section 5.01 of this revenue procedure only as an itemized deduction. This itemized deduction is subject to the 2-percent floor on miscellaneous itemized deductions provided in § 67.

.08 A self-employed individual may deduct an amount computed pursuant to section 5.01 of this revenue procedure in determining adjusted gross income under § 62(a)(1).

.09 If a payor’s reimbursement or other expense allowance arrangement evidences a pattern of abuse of the rules of § 62(c) and the regulations thereunder, all payments under the arrangement will be treated as made under a nonaccountable plan. Thus, such 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. See §§ 1.62–2(c)(3), (c)(5), and (h)(2).
