SECTION 6. LIMITATIONS AND
Internal Revenue Bulletin 2004-42 · 2026-10-03 edition · updated 2026-10-04 · United States
SPECIAL RULES
.01 In general . The federal per diem rate and the federal M&IE rate described in section 3.02 of this revenue procedure for the locality of travel will be applied in the same manner as applied under the Federal Travel Regulations, 41 C.F.R. Part 301–11 (2004), except as provided in sections 6.02 through 6.04 of this revenue procedure.
.02 Federal per diem rate . A receipt for lodging expenses is not required in determining the amount of expenses deemed substantiated under section 4.01 or 5.01 of this revenue procedure. See section 7.01 of this revenue procedure for the requirement that the employee substantiate the time, place, and business purpose of the expense.
.03 Federal per diem or M&IE rate . A payor is not required to reduce the federal per diem rate or the federal M&IE rate for the locality of travel for meals provided in kind, provided the payor has a reasonable belief that meal and incidental expenses were or will be incurred by the employee during each day of travel.
.04 Proration of the federal per diem or M&IE rate . Pursuant to the Federal Travel Regulations, in determining the federal per diem rate or the federal M&IE rate for the locality of travel, the full applicable federal M&IE rate is available for a full day of travel from 12:01 a.m. to 12:00 midnight. The method described in section 6.04(1) of this revenue procedure must be used for purposes of determining the amount deemed substantiated under section 4.03 or 4.05 of this revenue procedure for partial days of travel away from home. For purposes of determining the amount deemed substantiated under section 4.01, 4.02, 4.04, or 5 of this revenue procedure
for partial days of travel away from home, either of the following methods may be used to prorate the federal M&IE rate to determine the federal per diem rate or the federal M&IE rate for the partial days of travel:
(1) The rate may be prorated using the method prescribed by the Federal Travel Regulations. Currently the Federal Travel Regulations allow three-fourths of the applicable federal M&IE rate for each partial day during which the employee or self-employed individual is traveling away from home in connection with the performance of services as an employee or self-employed individual. The same ratio may be applied to prorate the allowance for incidental expenses described in section 4.05 of this revenue procedure; or
(2) The rate may be prorated using any method that is consistently applied and in accordance with reasonable business practice. For example, if an employee travels away from home from 9 a.m. one day to 5 p.m. the next day, a method of proration that results in an amount equal to two times the federal M&IE rate will be treated as being in accordance with reasonable business practice (even though only one and a half times the federal M&IE rate would be allowed under the Federal Travel Regulations).
.05 Application of the appropriate § 274(n) limitation on meal expenses . Except as provided in section 6.05(4), all or part of the amount of an expense deemed substantiated under this revenue procedure is subject to the appropriate limitation under § 274(n) (see section 2.02 of this revenue procedure) on the deductibility of food and beverage expenses.
(1) If an amount for meal and incidental expenses is computed pursuant to section 4.03 of this revenue procedure, the taxpayer must treat that amount as an expense for food and beverages.
(2) If a per diem allowance is paid only for meal and incidental expenses, the payor must treat an amount equal to the lesser of the allowance or the federal M&IE rate for the locality of travel for each day (or partial day, see section 6.04 of this revenue procedure) as an expense for food and beverages.
(3) If a per diem allowance is paid for lodging, meal, and incidental expenses, the payor must treat an amount equal to the federal M&IE rate for the locality of travel
2004–42 I.R.B. 690 October 18, 2004
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 § 1.274–5(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.
.08 A self-employed individual who pays or incurs meal expenses for a calendar day (or partial day) of travel away from home may deduct an amount computed pursuant to section 4.03 of this revenue procedure in determining adjusted gross
employee’s Form W–2, and is subject to withholding and payment of employment taxes.
.07 Related parties . Sections 4.01 and 5 of this revenue procedure do not apply if a payor and an employee are related within the meaning of § 267(b), but for this purpose the percentage of ownership interest referred to in § 267(b)(2) shall be 10 percent.
