26 CFR 1.267A-1: A-1 Disallowance of certain interest and royalty deductions.

(a) Scope. This section and §§ 1.267A-2 through 1.267A-5 provide rules regarding when a deduction for any interest or royalty paid or accrued is disallowed under section 267A. Section 1.267A-2 describes hybrid and branch arrangements. Section 1.267A-3 provides rules for determining income inclusions and provides that certain amounts are not amounts for which a deduction is disallowed. Section 1.267A-4 provides an imported mismatch rule. Section 1.267A-5 sets forth definitions and special rules that apply for purposes of section 267A. Section 1.267A-6 illustrates the application of section 267A through examples. Section 1.267A-7 provides applicability dates.

(b) Disallowance of deduction. This paragraph (b) sets forth the exclusive circumstances in which a deduction is disallowed under section 267A. Except as provided in paragraph (c) of this section, a specified party's deduction for any interest or royalty paid or accrued (the amount paid or accrued with respect to the specified party, a specified payment) is disallowed under section 267A to the extent that the specified payment is described in this paragraph (b). See also § 1.267A-5(b)(5) (treating structured payments as interest paid or accrued for purposes of section 267A and the regulations in this part under section 267A). A specified payment is described in this paragraph (b) to the extent that it is—

(1) A disqualified hybrid amount, as described in § 1.267A-2 (hybrid and branch arrangements);

(2) A disqualified imported mismatch amount, as described in § 1.267A-4 (payments offset by a hybrid deduction); or

(3) A specified payment for which the requirements of the anti-avoidance rule of § 1.267A-5(b)(6) are satisfied.

(c) De minimis exception. Paragraph (b) of this section does not apply to a specified party for a taxable year in which the sum of the specified party's specified payments that but for this paragraph (c) would be described in paragraph (b) of this section is less than $50,000. For purposes of this paragraph (c), specified parties that are related (within the meaning of § 1.267A-5(a)(14)) are treated as a single specified party.
