(i) * * * Further, a withholding agent is not required to withhold on a payment that it can reliably associate with documentation indicating that the payee is a U.S. branch treated as a U.S. person (as defined in § 1.1471-1(b)(135)) or is a U.S. branch of an FFI that is not treated as a U.S. person but that applies the rules described in § 1.1471-4(d)(2)(iii)(C). * * *

(3) Determination of whether the payment is made to a QI, WP, or WT. A withholding agent may treat the person who receives a payment as a QI, WP, or WT if the withholding agent can reliably associate the payment with a valid Form W-8IMY, as described in paragraph (c)(3)(iii) of this section, that indicates that the person who receives the payment is a QI, WP, or WT, provides the person's QI-EIN, WP-EIN, or WT-EIN, and the person's GIIN, if applicable.

(G) Combined reporting on Form 8966 following merger or bulk acquisition. If a participating FFI (successor) acquires accounts of another participating FFI (predecessor) in a merger or bulk acquisition of accounts, the successor may assume the predecessor's obligations to report the acquired accounts under paragraph (d) of this section with respect the calendar year in which the merger or acquisition occurs (acquisition year), provided that the requirements in paragraphs (d)(2)(ii)(G)( 1) through ( 4) of this section are satisfied. If the requirements of paragraphs (d)(2)(ii)(G)( 1) through ( 4) of this section are not satisfied, both the predecessor and the successor are required to report the acquired accounts for the portion of the acquisition year that it maintains the account.

( 2) If the U.S. branch of an FFI is not treated as a U.S. person and applies the rules described in § 1.1471-4(d)(2)(iii)(C) and provides the withholding agent with a withholding certificate that transmits information regarding its reporting pools referenced in paragraph (d)(4)(i)(B) of this section or information regarding each recipient that is an account holder or payee of the U.S. branch, the withholding agent must complete a separate Form 1042-S issued to the U.S. branch for each such pool to the extent required on the form and its accompanying instructions or must complete a separate Form 1042-S issued to each recipient whose documentation is associated with the U.S. branch's withholding certificate as described in paragraph (d)(4)(ii)(A) of this section and report the U.S. branch as an entity not treated as a recipient; or

( 3) If the U.S. branch of an FFI is not treated as a U.S. person and applies the rules described in § 1.1471-4(d)(2)(iii)(C) to the extent it fails to provide sufficient information regarding its account holders or payees, the withholding agent shall report the recipient of the payment as an unknown recipient to the extent recipient information is not provided and report the U.S. branch as provided in paragraph (d)(4)(ii)(A) of this section for an entity not treated as a recipient.

(ii) * * *

(C) Disregarded entities. If a U.S. withholding agent makes a payment to a disregarded entity and receives a valid withholding certificate or other documentary evidence from the person that is the single owner of such disregarded entity, the withholding agent must file a Form 1042-S treating the single owner as the recipient in accordance with the instructions to the Form 1042-S.

(iii) Reporting by participating FFIs and deemed-compliant FFIs (including QIs, WPs, and WTs) and U.S. branches of FFIs not treated as U.S. persons —(A) In general. Except as otherwise provided in paragraph (d)(4)(iii)(B) (relating to NQIs, NWPs, NWTs, and FFIs electing under section 1471(b)(3)) and § 1.1471-4(d)(2)(ii)(F) (relating to transitional payee-specific reporting for payments to nonparticipating FFIs), a participating FFI or deemed-compliant FFI (including a QI, WP, or WT), and a U.S. branch of an FFI that is not treated as a U.S. person that applies the rules described in § 1.1471-4(d)(2)(iii)(C) that makes a payment that is a chapter 4 reportable amount to a recalcitrant account holder or nonparticipating FFI must complete a Form 1042-S to report such payments. A participating FFI or registered deemed-compliant FFI (including a QI, WP, or WT), and a U.S. branch of an FFI that is not treated as a U.S. person that applies the rules described in § 1.1471-4(d)(2)(iii)(C) may report in pools consisting of its recalcitrant account holders and payees that are nonparticipating FFIs. With respect to recalcitrant account holders, the FFI may report in pools consisting of recalcitrant account holders within a particular status described in § 1.1471-4(d)(6) and within a particular income code. Except as otherwise provided in § 1.1471-4(d)(2)(ii)(F), with respect to payees that are nonparticipating FFIs, the FFI may report in pools consisting of one or more nonparticipating FFIs that fall within a particular income code and within a particular status code described in the instructions to Form 1042-S. Alternatively, a participating FFI or registered deemed-compliant FFI (including a QI, WP, or WT) and a U.S. branch of an FFI that is not treated as a U.S. person that applies the rules described in § 1.1471-4(d)(2)(iii)(C) may (and a certified deemed-compliant FFI is required to) perform payee-specific reporting to report a chapter 4 reportable amount paid to a recalcitrant account holder or a nonparticipating FFI when withholding was applied (or should have applied) to the payment.

(B) Special reporting requirements of participating FFIs, deemed-compliant FFIs, FFIs that make an election under section 1471(b)(3), and U.S. branches of FFIs not treated as U.S. persons. Except as otherwise provided in § 1.1471-4(d)(2)(ii)(F), a participating FFI or deemed-compliant FFI that is an NQI, NWP, or NWT, and a U.S. branch of an FFI that is not treated as a U.S. person that applies the rules described in § 1.1471-4(d)(2)(iii)(C) or an FFI that has made an election under section 1471(b)(3) and has provided sufficient information to its withholding agent to withhold and report the payment is not required to report the payment on Form 1042-S as described in paragraph (d)(4)(iii)(A) of this section if the payment is made to a nonparticipating FFI or recalcitrant account holder and its withholding agent has withheld the correct amount of tax on such payment and correctly reported the payment on a Form 1042-S. Such FFI or branch is required to report a payment, however, when the FFI knows, or has reason to know, that less than the required amount has been withheld by the withholding agent on the payment or the withholding agent has not correctly reported the payment on Form 1042-S. In such case, the FFI or branch must report on Form 1042-S to the extent required under paragraph (d)(4)(iii)(A) of this section. See, however, § 1.1471-4(d)(6) for the requirement to report certain aggregate information regarding accounts held by recalcitrant account holders on Form 8966, “FATCA Report,” regardless of whether withholdable payments are made to such accounts.
