§ 1.1441-5. Withholding on payments to partnerships, trusts, and estates.

¶(i) U.S. partnerships—

¶(ii) U.S. simple trusts. A U.S. trust that is described in section 651(a) (a U.S. simple trust) is required to withhold under chapter 3 of the Internal Revenue Code as a withholding agent on the distributable net income includible in the gross income of a foreign beneficiary to the extent the distributable net income is an amount subject to withholding (as defined in § 1.1441-2(a)). A U.S. simple trust shall withhold when a distribution is made to a foreign beneficiary. The U.S. trust may make a reasonable estimate of the portion of the distribution that constitutes distributable net income consisting of an amount subject to withholding and apply the appropriate rate of withholding to the estimated amount. If, at the end of the taxable year in which the distribution is made, the U.S. simple trust determines that it underwithheld under section 1441 or 1442, the trust shall be liable as a withholding agent for the amount under withheld under section 1461. No penalties shall be imposed for failure to withhold and deposit the tax if the U.S. simple trust's estimate was reasonable and the trust pays the underwithheld amount on or before the due date of Form 1042 under section 1461. Any payment of underwithheld amounts by the U.S. simple trust shall not be treated as income subject to additional withholding even if that amount is treated as additional income to the foreign beneficiary, unless the additional amount is income to the foreign beneficiary as a result of a contractual arrangement between the parties regarding the satisfaction of the foreign beneficiary's tax liability. To the extent a U.S. simple trust is required to, but does not, distribute such income to a foreign beneficiary, the U.S. trust must withhold on the foreign beneficiary's allocable share at the time the income is required (without extension) to be reported on Form 1042-S under § 1.1461-1(c).

¶(iii) U.S. complex trusts and U.S. estates. A U.S. trust that is not a trust described in section 651(a) (see paragraph (b)(2)(ii) of this section) or sections 671 through 679 (see paragraph (b)(2)(iv) of this section) (a U.S. complex trust) is required to withhold under chapter 3 of the Internal Revenue Code (Code) as a withholding agent on the distributable net income includible in the gross income of a foreign beneficiary to the extent the distributable net income consists of an amount subject to withholding (as defined in § 1.1441-2(a)) that is, or is required to be, distributed currently. The U.S. complex trust shall withhold when a distribution is made to a foreign beneficiary. The trust may use the same procedures regarding an estimate of the amount subject to withholding as a U.S. simple trust under paragraph (b)(2)(ii) of this section. To the extent an amount subject to withholding is required to be, but is not actually, distributed, the U.S. complex trust must withhold on the foreign beneficiary's allocable share at the time the income is required to be reported on Form 1042-S under § 1.1461-1(c), without extension. A U.S. estate is required to withhold under chapter 3 of the Code on the distributable net income includible in the gross income of a foreign beneficiary to the extent the distributable net income consists of an amount subject to withholding (as defined in § 1.1441-2(a)) that is actually distributed. A U.S. estate may also use the reasonable estimate procedures of paragraph (b)(2)(ii) of this section. However, those procedures apply to an estate that has a taxable year other than a calendar year only if the estate files an amended return on Form 1042 for the calendar year in which the distribution was made and pays the underwithheld tax and interest within 60 days after the close of the taxable year in which the distribution was made.

¶(iv) U.S. grantor trusts. A U.S. trust that is described in section 671 through 679 (a U.S. grantor trust) must withhold on any income includible in the gross income of a foreign person that is treated as an owner of the grantor trust to the extent the amount includible consists of an amount that is subject to withholding (as described in § 1.1441-2(a)). The withholding must occur at the time the income is received by, or credited to, the trust.

¶(v) Subsequent distribution. If a U.S. partnership or U.S. trust withholds on a foreign partner, beneficiary, or owner's share of an amount subject to withholding before the amount is actually distributed to the partner, beneficiary, or owner, withholding is not required when the amount is subsequently distributed.

¶(vi) Coordination with chapter 4 requirements for U.S. partnerships, trusts, and estates. To the extent that a U.S. partnership is required to withhold on an amount under chapter 4 with respect to a partner, beneficiary, or owner, the partnership, trust, or estate must apply the rules described in § 1.1473-1(a)(5) to determine when it must withhold on the amount under chapter 4. In a case in which withholding applies under chapter 4 to such an amount, see § 1.1441-3(a)(2) to coordinate with withholding that otherwise applies to such an amount under this paragraph (b).

¶(i) Payments treated as made to partners. Except as otherwise provided in paragraph (c)(1)(ii) or (iv) of this section, the payees of a payment to a person that the withholding agent may treat as a nonwithholding foreign partnership under paragraph (c)(3)(i) or (d)(2) of this section are the partners (looking through partners that are foreign intermediaries or flow-through entities) as follows—

¶(ii) Payments treated as made to the partnership. A payment to a person that the withholding agent may treat as a foreign partnership is treated as a payment to the foreign partnership and not to its partners only if—

¶(iii) Rules for reliably associating a payment with documentation. For rules regarding the reliable association of a payment with documentation, see § 1.1441-1(b)(2)(vii). In the absence of documentation, see §§ 1.1441-1(b)(3) and 1.6049-5(d) and paragraphs (d) and (e)(6) of this section for applicable presumptions.

¶(iv) Coordination with chapter 4 for payments made to foreign partnerships. A withholding agent that makes a payment of U.S. source FDAP income to a foreign partnership that is a withholdable payment to which withholding under chapter 4 applies must apply the rules described in § 1.1473-1(a)(5)(vi) to determine when the payment is treated as made to a partner in the partnership for purposes of chapter 4. In a case in which withholding applies under chapter 4 to a withholdable payment made to a foreign partnership, see § 1.1441-3(a)(2) to coordinate with withholding otherwise required under this paragraph (c) with respect to the amount of the payment included in the gross income of a partner. For when a withholding agent may reliably associate a withholdable payment with a chapter 4 withholding rate pool in lieu of obtaining documentation for each payee include in the pool, see § 1.1441-1(e)(3)(iv)(C)(2) (substituting the term nonwithholding foreign partnership for the term nonqualified intermediary).

¶(v) Examples. The rules of paragraphs (c)(1)(i) and (ii) of this section are illustrated by the following examples. Each example assumes that all payments are not withholdable payments and thus no withholding applies under chapter 4.

¶(i) Reliance on claim of withholding foreign partnership status. A withholding foreign partnership is a foreign partnership that has entered into an agreement with the IRS, as described in paragraph (c)(2)(ii) of this section, with respect to distributions and guaranteed payments it makes to its partners. A withholding agent that can reliably associate a payment with a certificate described in paragraph (c)(2)(iv) of this section may treat the person to whom it makes the payment as a withholding foreign partnership for purposes of withholding under chapters 3 and 4 of the Code, information reporting under chapter 61 of the Code, backup withholding under section 3406, and withholding under other provisions of the Code. Furnishing such a certificate is in lieu of transmitting to a withholding agent withholding certificates or other appropriate documentation for its partners. Although the withholding foreign partnership generally will be required to obtain withholding certificates or other appropriate documentation from its partners pursuant to its agreement with the IRS, it generally will not be required to attach such documentation to its withholding foreign partnership withholding certificate to the extent it is permitted to act as a withholding foreign partnership with respect to the payment under its agreement. In addition, the IRS may permit a foreign partnership to act as a qualified intermediary under § 1.1441-1(e)(5)(ii)(D) with respect to its partners in appropriate circumstances.

¶(ii) Withholding agreement. The IRS may, upon request, enter into a withholding agreement with a foreign partnership pursuant to such procedures as the IRS may prescribe in published guidance (see § 601.601(d)(2) of this chapter). Under the withholding agreement, a foreign partnership shall generally be subject to the applicable withholding and reporting provisions applicable to withholding agents and payors as defined in § 1.6049-4(a) under chapters 3, 4, and 61 of the Code, section 3406, the regulations under those provisions, and other withholding provisions of the Code, except to the extent provided under the withholding agreement. Under the withholding agreement, a foreign partnership may agree to act as an acceptance agent to perform the duties described in § 301.6109-1(d)(3)(iv)(A) of this chapter. For a foreign partnership that is an FFI, the withholding agreement will require the partnership to assume the requirements of a participating FFI, a registered deemed-compliant FFI, or an FFI treated as a deemed-compliant FFI under an applicable IGA that is subject to due diligence and reporting requirements with respect to its U.S. accounts similar to those applicable to a registered deemed-compliant FFI under § 1.1471-5(f)(1). The withholding agreement may specify the manner in which applicable procedures for adjustments for underwithholding and overwithholding, including refund procedures, apply to the withholding foreign partnership and its partners and the extent to which applicable procedures may be modified. In particular, the withholding agreement may allow a withholding foreign partnership to claim refunds of overwithheld amounts on behalf of its customers. In addition, the withholding agreement must specify the manner in which the IRS will verify the partnership's compliance with its agreement, including the requirements for a periodic review of the partnership's compliance with the withholding agreement and the procedures for the partnership to certify to its compliance with the withholding agreement. A withholding foreign partnership must file a return on Form 1042, “Annual Withholding Tax Return for U.S. Source Income of Foreign Persons,” and information returns on Form 1042-S, “Foreign Person's U.S. Source Income Subject to Withholding.” The withholding agreement may also require a withholding foreign partnership to file a partnership return under section 6031(a) and partner statements under 6031(b), including for each U.S. partner to the extent required in the agreement. Additionally, a partnership that is an FFI will be required to file Form 8966, “FATCA Report” to the extent provided in the withholding agreement.

¶(iii) Withholding responsibility. A withholding foreign partnership must assume primary withholding responsibility under both chapters 3 and 4 of the Code to the extent required in the withholding agreement. It is not required to provide information to the withholding agent regarding each partner's distributive share of the payment (including a withholdable payment). The withholding foreign partnership will be responsible for reporting the payments under §§ 1.1461-1(c), 1.1474-1(d), and chapter 61 of the Code and filing Form 1042 (to the extent required in the withholding agreement). A withholding agent making a payment to a withholding foreign partnership is not required to withhold any amount under chapters 3 and 4 of the Code on the payment unless it has actual knowledge or reason to know that the foreign partnership is not acting as a withholding foreign partnership with respect to the payment or has not withheld to the extent required. The withholding foreign partnership shall withhold the payments under the same procedures and at the same time as prescribed for withholding by a U.S. partnership under paragraph (b)(2) of this section, except that, for purposes of determining the partner's status, the provisions of paragraph (d)(4) of this section shall apply.

¶(iv) Withholding certificate from a withholding foreign partnership. The rules of § 1.1441-1(e)(4) shall apply to withholding certificates described in this paragraph (c)(2)(iv). A withholding certificate furnished by a withholding foreign partnership is valid with regard to any partner on whose behalf the certificate is furnished only if it is furnished on a Form W-8, an acceptable substitute form, or such other form as the IRS may prescribe, it is signed under penalties of perjury by a partner with authority to sign for the partnership, its validity has not expired, and it contains the information, statement, and certifications described in this paragraph (c)(2)(iv) as follows—

¶(i) Reliance on claim of foreign partnership status. A withholding agent may treat a person as a nonwithholding foreign partnership if it receives from that person a nonwithholding foreign partnership withholding certificate as described in paragraph (c)(3)(iii) of this section. A withholding agent that does not receive a nonwithholding foreign partnership withholding certificate or does not receive a valid withholding certificate from an entity it knows, or has reason to know, is a foreign partnership must apply the presumption rules of §§ 1.1441-1(b)(3) and 1.6049-5(d) and paragraphs (d) and (e)(6) of this section. In addition, to the extent a withholding agent cannot, prior to a payment, reliably associate the payment with valid documentation from a payee that is associated with the nonwithholding foreign partnership withholding certificate or has insufficient information to report the payment on Form 1042-S or Form 1099, to the extent reporting is required, the withholding agent must apply the presumption rules. See § 1.1441-1(b)(2)(vii)(A) and (B) for rules regarding reliable association. See, however, § 1.1441-1(e)(3)(iv)(C)(2) for when a withholding agent may reliably associate a withholdable payment with a chapter 4 withholding rate pool in lieu of obtaining documentation for each payee included in the pool (substituting the term nonwithholding foreign partnership for the term nonqualified intermediary). See also § 1.1441-1(e)(3)(iv)(A) for when a withholding agent may reliably associate a payment with a chapter 4 withholding rate pool of U.S. payees. See paragraph (c)(3)(iv) of this section and § 1.1441-1(e)(3)(iv) for alternative procedures permitting allocation information to be received after a payment is made.

¶(ii) Reliance on claim of reduced withholding by a partnership for its partners. This paragraph (c)(3)(ii) describes the manner in which a withholding agent may rely on a claim of reduced withholding when making a payment to a nonwithholding foreign partnership. To the extent that a withholding agent treats a payment to a nonwithholding foreign partnership as a payment to the nonwithholding foreign partnership's partners (whether direct or indirect) in accordance with paragraph (c)(1)(i) of this section, it may rely on a claim for reduced withholding by the partner if, prior to the payment, the withholding agent can reliably associate the payment (within the meaning of § 1.1441-1(b)(2)(vii)) with a valid withholding certificate or other appropriate documentation from the partner that establishes entitlement to a reduced rate of withholding. A withholding certificate or other appropriate documentation that establishes entitlement to a reduced rate of withholding is a beneficial owner withholding certificate described in § 1.1441-1(e)(2)(i), documentary evidence described in § 1.1441-6(c)(3) or (4) or § 1.6049-5(c)(1) (for a partner claiming to be a foreign person and a beneficial owner, determined under the provisions of § 1.1441-1(c)(6)), a Form W-9 described in § 1.1441-1(d) (for a partner claiming to be a U.S. payee), a withholding foreign partnership withholding certificate described in paragraph (c)(2)(iv) of this section, or a withholding statement allocating the payment to a chapter 4 withholding rate pool of U.S. payees. For when the withholding agent can reliably associate the payment with a chapter 4 withholding rate pool, see paragraph (c)(3)(i) of this section. See also § 1.1441-3(a)(2) (coordinating withholding under chapter 3 when withholding under chapter 4 is applied to a payment). Unless a nonwithholding foreign partnership withholding certificate is provided for income claimed to be effectively connected with the conduct of a trade or business in the United States, a claim must be presented for each portion of the payment that represents an item of income includible in the distributive share of a partner as required under paragraph (c)(3)(iii)(C) of this section. When making a claim for several partners, the partnership may present a single nonwithholding foreign partnership withholding certificate to which the partners' certificates or other appropriate documentation are associated. Where the nonwithholding foreign partnership withholding certificate is provided for income claimed to be effectively connected with the conduct of a trade or business in the United States under paragraph (c)(3)(iii)(D) of this section, the claim may be presented without having to identify any partner's distributive share of the payment.

¶(iii) Withholding certificate from a nonwithholding foreign partnership. A nonwithholding foreign partnership shall provide a nonwithholding foreign partnership withholding certificate with respect to reportable amounts received by the nonwithholding foreign partnership. A nonwithholding foreign partnership withholding certificate is valid only to the extent it is furnished on a Form W-8 (or an acceptable substitute form or such other form as the IRS may prescribe), it is signed under penalties of perjury by a partner with authority to sign for the partnership, its validity has not expired, and it contains the information, statements, and certifications described in this paragraph (c)(3)(iii) and paragraph (c)(3)(iv) of this section, and the withholding certificates and other appropriate documentation for all the persons to whom the certificate relates are associated with the certificate. The rules of § 1.1441-1(e)(4) shall apply to withholding certificates described in this paragraph (c)(3)(iii). No withholding certificates or other appropriate documentation from persons who derive income through a partnership (whether or not U.S. exempt recipients) are required to be associated with the nonwithholding foreign partnership withholding certificate if the certificate is furnished solely for income claimed to be effectively connected with the conduct of a trade or business in the United States. Withholding certificates and other appropriate documentation that may be associated with the nonwithholding foreign partnership withholding certificate consist of beneficial owner withholding certificates under § 1.1441-1(e)(2)(i), intermediary withholding certificates under § 1.1441-1(e)(3)(i), withholding foreign partnership withholding certificates under paragraph (c)(2)(iv) of this section, nonwithholding foreign partnership withholding certificates under this paragraph (c)(3)(iii), withholding certificates from foreign trusts or estates under paragraph (e) of this section, documentary evidence described in § 1.1441-6(c)(3) or (4) or documentary evidence described in § 1.6049-5(c)(1), and any other documentation or certificates applicable under other provisions of the Internal Revenue Code or regulations that certify or establish the status of the payee or beneficial owner as a U.S. or a foreign person. Nothing in this paragraph (c)(3)(iii) shall require a nonwithholding foreign partnership to furnish original documentation. Copies of certificates or documentary evidence may be transmitted to the U.S. withholding agent, in which case the nonwithholding foreign partnership must retain the original documentation for the same time period that the copy is required to be retained by the withholding agent under § 1.1441-1(e)(4)(iii) and must provide it to the withholding agent upon request. The information, statement, and certifications required on the withholding certificate are as follows—

¶(iv) Withholding statement provided by nonwithholding foreign partnership and coordination with chapter 4. The provisions of § 1.1441-1(e)(3)(iv) (regarding a withholding statement) shall apply to a nonwithholding foreign partnership by substituting the term nonwithholding foreign partnership for the term nonqualified intermediary, including when a nonwithholding foreign partnership may provide to a withholding agent a withholding statement that includes a chapter 4 withholding rate pool in lieu of information with respect to each partner that is a payee of a payment.

¶(v) Withholding and reporting by a foreign partnership. A nonwithholding foreign partnership described in this paragraph (c)(3) that receives an amount subject to withholding (as defined in § 1.1441-2(a)) shall be required to withhold and report such payment under chapter 3 of the Code and the regulations thereunder except as otherwise provided in this paragraph (c)(3)(v). A nonwithholding foreign partnership shall not be required to withhold and report if it has provided a valid nonwithholding foreign partnership withholding certificate, it has provided all of the information required by paragraph (c)(3)(iv) of this section (withholding statement), and it does not know, and has no reason to know, that another withholding agent failed to withhold the correct amount or failed to report the payment correctly under § 1.1461-1(c). A nonwithholding foreign partnership is also not required to withhold and report under this paragraph (c)(3) to the extent that withholding under chapter 4 was applied to a payment that is includible in the gross income of a partner in the partnership. See also § 1.1441-3(a)(2) for coordination rules when withholding under chapter 4 has been applied to a withholdable payment. A withholding foreign partnership's obligations to withhold and report shall be determined in accordance with its withholding foreign partnership agreement.

¶(i) Payments for which beneficiaries and owners are payees. For purposes of the regulations under chapters 3 and 61 of the Internal Revenue Code and section 3406, a foreign simple trust is not a beneficial owner or a payee of a payment. Also, a foreign grantor trust (or a portion of a trust that is a foreign grantor trust) is not considered a beneficial owner or a payee of a payment. Except as otherwise provided in paragraph (e)(3)(ii) of this section, the payees of a payment made to a person that the withholding agent may treat as a foreign simple trust or a foreign grantor trust (or a portion of a trust that is a foreign grantor trust) are determined under the rules of this paragraph (e)(3)(i). The payees shall be treated as the beneficial owners if they may be so treated under § 1.1441-1(c)(6)(ii)(C) and they provide documentation supporting their status as the beneficial owners. The payees of a payment to a foreign simple trust or foreign grantor trust are determined as follows—

¶(ii) Payments for which trust is payee. A payment to a person that the withholding agent may treat as made to a foreign trust under paragraph (e)(5)(iii) of this section is treated as a payment to the trust, and not to a beneficiary of the trust, only if—

¶(iii) Coordination with chapter 4 for payments made to foreign simple trusts and foreign grantor trusts. A withholding agent that makes a payment of U.S. source FDAP income to a foreign simple trust or foreign grantor trust that is a withholdable payment to which withholding under chapter 4 applies must apply the rules described in § 1.1473-1(a)(5)(vi) to determine when the payment is treated as made to a beneficiary or owner of the trust for purposes of chapter 4. In a case in which withholding applies under chapter 4 to a withholdable payment made to a foreign simple trust or foreign grantor trust, see § 1.1441-3(a)(2) to coordinate withholding otherwise required under this paragraph (e) with respect to the amount of the payment included in the gross income of the payee of the payment. For when a withholding agent may reliably associate a withholdable payment with a chapter 4 withholding rate pool in lieu of obtaining documentation for each payee included in the pool, see § 1.1441-1(e)(3)(iv)(C)(2) (substituting the term nonwithholding foreign trust for the term nonqualified intermediary).

¶(i) Reliance on claim of foreign simple trust or foreign grantor trust status. A withholding agent may treat a person as a foreign simple trust or foreign grantor trust if it receives from that person a foreign simple trust or foreign grantor trust withholding certificate as described in paragraph (e)(5)(iii) of this section. A withholding agent must apply the presumption rules of §§ 1.1441-1(b)(3) and 1.6049-5(d) and paragraphs (d) and (e)(6) of this section to the extent it cannot, prior to the payment, reliably associate a payment (within the meaning of § 1.1441-1(b)(2)(vii)) with a valid foreign simple trust or foreign grantor trust withholding certificate, it cannot reliably determine how much of the payment relates to valid documentation provided by a payee (e.g., a person that is not itself a nonqualified intermediary, flow-through entity, or U.S. branch) associated with the foreign simple trust or foreign grantor trust withholding certificate, or it does not have sufficient information to report the payment on Form 1042-S or Form 1099, if reporting is required. See § 1.1441-1(b)(2)(vii)(A) and (B). See, however, § 1.1441-1(e)(3)(iv)(C)(2) for when a withholding agent may reliably associate a withholdable payment with a chapter 4 withholding rate pool in lieu of obtaining documentation for each payee included in a pool (substituting the term nonwithholding foreign trust for the term nonqualified intermediary). See also § 1.1441-1(e)(3)(iv)(A) for when a withholding agent may reliably associate a payment with a chapter 4 withholding rate pool of U.S. payees.

¶(ii) Reliance on claim of reduced withholding by a foreign simple trust or foreign grantor trust for its beneficiaries or owners. This paragraph (e)(5)(ii) describes the manner in which a withholding agent may rely on a claim of reduced withholding when making a payment to a foreign simple trust or foreign grantor trust. To the extent that a withholding agent treats a payment to a foreign simple trust or foreign grantor trust as a payment to payees other than the trust in accordance with paragraph (e)(3)(i) of this section, it may rely on a claim for reduced withholding by a beneficiary or owner if, prior to the payment, the withholding agent can reliably associate the payment (within the meaning of § 1.1441-1(b)(2)(vii)) with a valid withholding certificate or other appropriate documentation from a payee or beneficial owner that establishes entitlement to a reduced rate of withholding. A withholding certificate or other appropriate documentation that establishes entitlement to a reduced rate of withholding is a beneficial owner withholding certificate described in § 1.1441-1(e)(2)(i) or documentary evidence described in § 1.1441-6(c)(3) or (4) or in § 1.6049-5(c)(1) (for a beneficiary or owner claiming to be a foreign person and a beneficial owner, determined under the provisions of § 1.1441-1(c)(6)), a Form W-9 described in § 1.1441-1(d) (for a beneficiary or owner claiming to be a U.S. payee), a withholding foreign partnership withholding certificate described in paragraph (c)(2)(iv) of this section, or a withholding statement allocating the payment to a chapter 4 withholding rate pool of U.S. payees. For when the withholding agent can reliably associate the payment with a chapter 4 withholding rate pool, see paragraph (c)(3)(i) of this section. See also § 1.1441-3(a)(2) (coordinating withholding under chapter 3 when withholding under chapter 4 is applied to a withholdable payment). Unless a foreign simple trust or foreign grantor trust withholding certificate is provided for income treated as income effectively connected with the conduct of a trade or business in the United States, a claim must be presented for each payee's portion of the payment. When making a claim for several payees, the trust may present a single foreign simple trust or foreign grantor trust withholding certificate with which the payees' certificates or other appropriate documentation are associated. Where the foreign simple trust or foreign grantor trust withholding certificate is provided for income that is treated as effectively connected with the conduct of a trade or business in the United States under paragraph (e)(5)(iii)(D) of this section, the claim may be presented without having to identify any beneficiary's or grantor's distributive share of the payment.

¶(iii) Withholding certificate from foreign simple trust or foreign grantor trust. A withholding certificate furnished by a foreign simple trust or a foreign grantor trust that is not a withholding foreign trust (within the meaning of paragraph (e)(5)(v) of this section) is valid only if it is furnished on a Form W-8, an acceptable substitute form, or such other form as the IRS may prescribe, it is signed under penalties of perjury by a trustee, its validity has not expired, it contains the information, statements, and certifications required by this paragraph (e)(5)(iii) and § 1.1441-1(e)(3)(iv), and the withholding certificates or other appropriate documentation for all of the payees (as determined under paragraph (e)(3)(i) of this section) to whom the certificate relates are associated with the foreign simple trust or foreign grantor trust withholding certificate. The rules of § 1.1441-1(e)(4) shall apply to withholding certificates described in this paragraph (e)(5)(iii). No withholding certificates or other appropriate documentation from persons who derive income through a foreign simple trust or a foreign grantor trust (whether or not U.S. exempt recipients) are required to be associated with the foreign simple trust or foreign grantor trust withholding certificate if the certificate is furnished solely for income that is treated as effectively connected with the conduct of a trade or business in the United States. Withholding certificates and other appropriate documentation (as determined under paragraph (e)(3)(i) of this section) that may be associated with a foreign simple trust or foreign grantor trust withholding certificate consist of beneficial owner withholding certificates under § 1.1441-1(e)(2)(i), intermediary withholding certificates under § 1.1441-1(e)(3)(i), withholding foreign partnership withholding certificates under paragraph (c)(2)(iv) of this section, nonwithholding foreign partnership withholding certificates under paragraph (c)(3)(iii) of this section, withholding certificates from foreign trusts or estates under paragraph (e)(4) or (5)(iii) of this section, documentary evidence described in §§ 1.1441-6(c)(3) or (4), or 1.6049-5(c)(1), and any other documentation or certificates applicable under other provisions of the Internal Revenue Code or regulations that certify or establish the status of the payee or beneficial owner as a U.S. or a foreign person. Nothing in this paragraph (e)(5)(iii) shall require a foreign simple trust or foreign grantor trust to provide original documentation. Copies of certificates or documentary evidence may be passed up to the U.S. withholding agent, in which case the foreign simple trust or foreign grantor trust must retain the original documentation for the same time period that the copy is required to be retained by the withholding agent under § 1.1441-1(e)(4)(iii) and must provide it to the withholding agent upon request. The information, statement, and certifications required on a foreign simple trust or foreign grantor trust withholding certificate are as follows—

¶(iv) Withholding statement provided by a foreign simple trust or foreign grantor trust and coordination with chapter 4. The provisions of § 1.1441-1(e)(3)(iv) (regarding a withholding statement) shall apply to a foreign simple trust or foreign grantor trust by substituting the term foreign simple trust or foreign grantor trust for the term nonqualified intermediary, including when a withholding statement provided by a foreign simple trust or foreign grantor trust may include a chapter 4 withholding rate pool in lieu of information with respect to each owner or beneficiary that is a payee of a payment.

¶(v) Withholding foreign trusts. The IRS may enter into a withholding agreement with a foreign trust to treat the trust or estate as a withholding foreign trust. Such a withholding agreement shall generally follow the same principles as a withholding agreement with a withholding foreign partnership under paragraph (c)(2)(ii) of this section. A withholding agent may treat a payment to a withholding foreign trust in the same manner the withholding agent would treat a payment (including a withholdable payment) to a withholding foreign partnership. See § 1.1441-1(e)(5)(ii)(D). For a withholding foreign trust that is an FFI, the withholding agreement will require the withholding foreign trust to assume the requirements of either a participating FFI, registered deemed-compliant FFI, or an FFI treated as a deemed-compliant FFI under an applicable IGA that is subject to due diligence and reporting requirements with respect to its U.S. accounts similar to those applicable to a registered deemed-compliant FFI under § 1.1471-5(f)(1).

¶(i) In general. This paragraph (e)(6) contains the applicable presumptions for a withholding agent (including a trust or estate) to determine the classification and status of a trust or estate and its beneficiaries or owners in the absence of valid documentation. The provisions of § 1.1441-1(b)(3)(iv) (regarding the 90-day grace period) and § 1.1441-1(b)(3)(vii) through (ix) shall apply for purposes of this paragraph (e)(6).

¶(ii) Determination of status as U.S. or foreign trust or estate in the absence of documentation. In the absence of valid documentation that establishes the U.S. status of a trust or estate under paragraph (b)(1) of this section and of documentation that establishes the foreign status of a trust or estate under paragraph (e)(4) or (e)(5)(iii) of this section, the withholding agent shall determine the classification of the payee based upon the presumptions set forth in § 1.1441-1(b)(3)(ii). If, based upon those presumptions, the withholding agent classifies the payee as a trust or estate, the withholding agent shall apply the presumptions set forth in § 1.1441-1(b)(3)(iii)(A)(1) (applied by substituting the term trust for the term exempt recipient) to determine whether the trust or estate is a U.S. person or foreign person. An undocumented payee presumed to be a foreign trust shall be presumed to be a foreign complex trust. If a withholding agent has documentary evidence that establishes that an entity is a foreign trust, but the withholding agent cannot determine whether the foreign trust is a complex trust, a simple trust, or foreign grantor trust, the withholding agent shall presume that the trust is a foreign complex trust. Notwithstanding the preceding sentence, in the case of a foreign trust with a settlor that is a U.S. person for which a withholding agent has both a U.S. address and TIN, the withholding agent shall presume that the trust is a grantor trust when it cannot determine the status of the trust as a simple trust, complex trust, or grantor trust. See § 1.1471-3(f)(4) and (5) to determine the status of the payee for purposes of chapter 4.

¶(iii) Determination of beneficiary or owner's status in the absence of certain documentation. If a foreign simple trust or foreign grantor trust has provided a foreign simple trust or foreign grantor trust withholding certificate under paragraph (e)(5)(iii) of this section but the payment to such trust cannot be reliably associated with valid documentation from a specific beneficiary or owner of the trust, then any portion of a payment that a withholding agent cannot treat as reliably associated with valid documentation from a beneficiary or owner may be presumed made to a foreign payee. As a result, any payment of an amount subject to withholding is subject to withholding at a rate of 30 percent. Any such payment that is presumed to be made to an undocumented foreign person must be reported on Form 1042-S. See § 1.1461-1(c).
