U.S. payor, U.S. middleman, non-U.S. payor, and non-U.S. middleman. The terms payor and middleman have the meanings ascribed to them under §1.6049-4(a).

(A) A person described in section 7701(a)(30) (including a foreign branch or office of such person);

(F) [Reserved] For further guidance, see § 1.6049-5T(c)(5)(i)(F).
(ii) Reporting by U.S. payors in U.S. possessions. U.S. payors are not required to report on Form 1099 income that is from sources within a possession of the United States and that is exempt from taxation under section 931, 932, or 933, each of which sections exempts certain income from sources within a possession of the United States paid to a bona fide resident of that possession. For purposes of this paragraph (c)(5)(ii), a U.S. payor may treat the beneficial owner as a bona fide resident of the possession of the United States from which the income is sourced if, prior to payment of the income, the U.S. payor can reliably associate the payment with valid documentation that supports the claim of residence in the possession of the United States from which the income is sourced. This paragraph (c)(5)(ii) shall not apply if the U.S. payor has actual knowledge or reason to know that the documentation is unreliable or incorrect or that the income does not satisfy the requirements for exemption under section 931, 932, or 933. For the rules determining whether income is from sources within a possession of the United States, see section 937(b) and the regulations thereunder.
