Sec. 1.1446-1 Withholding tax on foreign partners' share of effectively connected taxable income.

(A) U.S. person.

A partner that is a U.S. person (other than a grantor trust described in this paragraph (c)(2)), including a domestic partnership and domestic simple or complex trust (including an estate), shall provide a valid Form W-9.

(B) Nonresident alien.

A Form W-8 (e.g., Form W-8BEN) submitted by a nonresident alien for purposes of withholding under section 1441 will generally be accepted for purposes of section 1446. If no such form is submitted for purposes of section 1441, such nonresident alien shall submit Form W-8BEN for purposes of section 1446.

(C) Foreign partnership.

A partner that is a foreign partnership generally shall provide a valid Form W-8IMY for purposes of section 1446. See § 1.1446-5 (permitting a lower-tier partnership to look through an upper-tier foreign partnership in certain circumstances when computing 1446 tax).

(D) Disregarded entities.

An entity that is disregarded as an entity separate from its owner under § 301.7701-3 of this chapter (whether domestic or foreign) shall not submit a Form W-8 (e.g., Form W-8BEN) or Form W-9. Instead, the owner of such entity for Federal tax purposes shall submit appropriate documentation to comply with this section. See §§ 301.7701-1 through 301.7701-3 of this chapter for determining the U.S. Federal tax classification of a partner.

(E) Domestic and foreign grantor trusts.

To the extent that a grantor or other person is treated as the owner of any portion of a trust under subpart E of subchapter J of the Internal Revenue Code, such trust shall provide documentation under this paragraph (c)(2) to identify the trust as a grantor trust and provide documentation on behalf of the grantor or other person treated as the owner of all or a portion of such trust as required by this paragraph (c)(2). If such trust is a foreign trust, the trust shall submit Form W-8IMY to the partnership identifying itself as a foreign grantor trust and shall provide such documentation (e.g., Forms W-8BEN, W-8IMY, W-8ECI, W-8EXP, or W-9) and information pertaining to its grantor or other owner to the partnership that permits the partnership to reliably associate (within the meaning of § 1.1441-1(b)(2)(vii)) such portion of the trust's allocable share of partnership ECTI with the grantor or other person that is the owner of such portion of the trust. If such trust is a domestic trust, the trust shall furnish the partnership a statement under penalty of perjury that the trust is, in whole or in part, a domestic grantor trust and such statement shall identify that portion of the trust that is treated as owned by a grantor or another person under subpart E of subchapter J of the Internal Revenue Code. The trust shall also provide such documentation and information (e.g., Forms W-8BEN, W-8IMY, W-8ECI, W-8EXP, or W-9) pertaining to its grantor or other owner(s) to the partnership that permits the partnership to reliably associate (within the meaning of § 1.1441-1(b)(2)(vii)) such portion of the trust's allocable share of partnership ECTI with the grantor or other person that is the owner of such portion of the trust.

(F) Nominees.

Where a nominee holds an interest in a partnership on behalf of another person, the beneficial owner of the partnership interest, not the nominee, shall submit a Form W-8 (e.g., Form W-8BEN) or Form W-9 to the partnership or nominee that is the withholding agent.

(G) Foreign governments, foreign tax-exempt organizations and other foreign persons.

A Form W-8 (e.g., Form W-8EXP) submitted by a partner that is a foreign government, foreign tax-exempt organization, or other foreign person for purposes of withholding under §§ 1441 through 1443 will also operate to establish the foreign status of such partner under this section. However, except as set forth in § 1.1446-3(c)(3) (regarding certain tax-exempt organizations described in section 501(c)), the submission of Form W-8EXP will have no effect on whether there is a 1446 tax due with respect to such partner's allocable share of partnership ECTI. However, except as set forth in §1.1446-2(b)(4)(iii) (regarding withholding qualified holders (as defined in §1.1445-1(g)(11)) and §1.1446-3(c)(3) (regarding certain tax-exempt organizations described in section 501(c)), the submission of Form W-8EXP (or successor) will have no effect on whether there is a 1446 tax due with respect to such partner's allocable share of partnership ECTI. If no Form W-8 is submitted for purposes of withholding under sections 1441 through 1443, then such government, tax-exempt organization, or person must generally submit Form W-8BEN.

(H) Foreign corporations, certain foreign trusts, and foreign estates. Consistent with the rules of this paragraph (c)(2) and paragraph (c)(3) of this section, a foreign corporation, a foreign trust (other than a foreign grantor trust described in paragraph (c)(2)(ii)(E) of this section), or a foreign estate may generally submit any appropriate Form W-8 (for example, Form W-8BEN-E or Form W-8IMY) to the partnership to establish its foreign status for purposes of section 1446. In addition, a foreign entity may also submit a certification of non-foreign status (including a Form W-8EXP) described in §1.1445-5(b)(3)(ii) for purposes of documenting itself as a withholding qualified holder (as defined in §1.1445-1(g)(11)).

(A) Partnership reliance on withholding certificate.

In general, for purposes of this section, a partnership may rely on a valid Form W-8 (e.g., Form W-8BEN) or Form W-9, or statement described in this paragraph (c)(2) from a partner, beneficial owner, or grantor trust to determine whether that person, beneficial owner, or the owner of a grantor trust, is a non-foreign or foreign partner for purposes of computing 1446 tax, and if such person is a foreign partner, to determine whether or not such person is a corporation for U.S. tax purposes. The rules of paragraph (c)(3) of this section shall apply to a partnership that receives a Form W-8IMY from a foreign grantor trust or a statement described in this paragraph (c)(2) from a domestic grantor trust, but does not receive a Form W-8 (e.g., Form W-8BEN) or Form W-9 identifying such grantor or other person. Further, a partnership may not rely on a Form W-8 or Form W-9, or statement described in this paragraph (c)(2), and such form or statement is therefore not valid for any installment period or Form 8804 filing date during which the partnership has actual knowledge or has reason to know that any information on the withholding certificate or statement is incorrect or unreliable and, if based on such knowledge or reason to know, the partnership should pay 1446 tax in an amount greater than would be the case if it relied on the certificate or statement.

(B) Reason to know.

A partnership has reason to know that information on a withholding certificate or statement is incorrect or unreliable if its knowledge of relevant facts or statements contained on the form or other documentation is such that a reasonably prudent person in the position of the withholding agent would question the claims made. See §§ 1.1441-1(e)(4)(viii) and 1.1441-7(b)(1) and (2).

(C) Subsequent knowledge and impact on penalties.

If the partnership does not have actual knowledge or reason to know that a Form W-8BEN, Form W-8IMY, Form W-8ECI, Form W-8EXP, Form W-9, or statement received from a partner, beneficial owner, or grantor trust contains incorrect or unreliable information, but it subsequently determines that the certificate or statement contains incorrect or unreliable information, and, based on such knowledge the partnership should pay 1446 tax in an amount greater than would be the case if it relied on the certificate or statement, then the partnership will not be subject to penalties for its failure to pay the 1446 tax in reliance on such certificate or statement for any installment payment date prior to the date that the determination is made. See §§ 1.1446-1(c)(4) and 1.1446-3 concerning penalties for failure to pay the withholding tax when a partnership knows or has reason to know that a withholding certificate or statement is incorrect or unreliable.

(A) When period of validity expires.

For purposes of this section, a Form W-8BEN, Form W-8IMY, Form W-8ECI, or Form W-8EXP submitted by a partner shall be valid until the end of the period of validity determined for such form under § 1.1441-1(e). With respect to a foreign partnership submitting Form W-8IMY, the period of validity of such form shall be determined under § 1.1441-1(e) as if such foreign partnership submitted the form required of a nonwithholding foreign partnership. See § 1.1441-1(e)(4)(ii).

(B) Required information for Forms W-8BEN, W-8IMY, W-8ECI, and W-8EXP.

Forms W-8BEN, W-8IMY, W-8ECI, and W-8EXP submitted under this section must contain the partner's name, permanent address and Taxpayer Identification Number (TIN), the country under the laws of which the partner is formed, incorporated or governed (if the person is not an individual), the classification of the partner for U.S. Federal tax purposes (e.g., partnership, corporation), and any other information required to be submitted by the forms or instructions for such form, as applicable.
