SECTION 8. WITHHOLDING AND

PAYMENT OF EMPLOYMENT TAXES

.01 The portion of a per diem allowance, if any, that relates to the days of business travel substantiated and that exceeds the amount deemed substantiated for those days under section 4.01, 4.02, or 5 of this revenue procedure is treated as paid under a nonaccountable plan and is subject to withholding and payment of employment taxes. See § 1.62–2(h)(2)(i)(B).

.02 In the case of a per diem allowance paid as a reimbursement, the excess described in section 8.01 of this revenue procedure is subject to withholding and payment of employment taxes in the payroll period in which the payor reimburses the expenses for the days of travel substantiated. See § 1.62–2(h)(2)(i)(B)(2).

.03 In the case of a per diem allowance paid as an advance, the excess described in section 8.01 of this revenue procedure is subject to withholding and payment of employment taxes no later than the first

required to return within a reasonable period of time (as defined in § 1.62–2(g)) the portion of the allowance that is attributable to the 2 unsubstantiated days of travel ($100), even though the employee is not required to return the portion of the allowance ($33) that exceeds the amount of the employee’s expenses deemed substantiated under section 4.02 of this revenue procedure ($117) for the 3 substantiated days of travel. However, the $33 excess portion of the allowance is treated as paid under a nonaccountable plan as discussed in section 7.04 of this revenue procedure.

.03 An employee is not required to include in gross income the portion of a per diem allowance received from a payor that is less than or equal to the amount deemed substantiated under the rules provided in section 4 or 5 of this revenue procedure if the employee substantiates the business travel expenses covered by the per diem allowance in accordance with section 7.01 of this revenue procedure. See § 1.274–5T(f)(2)(i). Assuming that the remaining requirements for an accountable plan provided in § 1.62–2 are satisfied, that 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).

.04 An employee is required to include in gross income only the portion of the per diem allowance received from a payor that exceeds the amount deemed substantiated under the rules provided in section 4 or 5 of this revenue procedure if the employee substantiates the business travel expenses covered by the per diem allowance in accordance with section 7.01 of this revenue procedure. See § 1.274–5T(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).

.05 If the amount of the expenses that is deemed substantiated under the rules provided in section 4.01, 4.02, or 5 of this revenue procedure is less than the amount of the employee’s business expenses for travel away from home, the employee may claim an itemized deduction for the amount by which the business travel ex

penses exceed the amount that is deemed substantiated, provided the employee substantiates all the business travel expenses (not just the excess over the federal per diem rate), includes on Form 2106, “ Em- ployee Business Expenses,” the deemed substantiated portion of the per diem allowance received from the payor, and includes in gross income the portion (if any) of the per diem allowance received from the payor that exceeds the amount deemed substantiated. See § 1.274–5T(f)(2)(iii). However, for purposes of claiming this itemized deduction with respect to meal and incidental expenses, 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 amount computed under section 4.03 of this revenue procedure minus the amount deemed substantiated under sections 4.02 and 7.01 of this revenue procedure. The itemized deduction is subject to the appropriate limitation (see section 2.02 of this revenue procedure) on meal and entertainment expenses provided in § 274(n) and the 2-percent floor on miscellaneous itemized deductions provided in § 67.

.06 An employee who pays or incurs amounts for meal expenses and does not receive a per diem allowance for meal and incidental expenses may deduct an amount computed pursuant to section 4.03 of this revenue procedure only as an itemized deduction. This itemized deduction is subject to the appropriate limitation on meal and entertainment expenses provided in § 274(n) and the 2-percent floor on miscellaneous itemized deductions provided in § 67. See section 7.07 of this revenue procedure for the treatment of an employee who does not pay or incur amounts for meal expenses and does not receive a per diem allowance for incidental expenses.

.07 An employee who does not pay or incur amounts for meal expenses and does not receive a per diem allowance for incidental expenses may deduct an amount computed pursuant to section 4.05 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. See section 7.06 of this revenue procedure for the treatment of an employee who pays or incurs amounts for meal expenses and does not receive a per diem allowance for meal and incidental expenses.
