Withholding certificate
(2) Withholding certificate. A withholding certificate under this paragraph (b)(2) is valid only if it is a Form W-8 and if, in addition to other applicable requirements, the Form W-8 includes the taxpayer identifying number of the organization whose name is on the certificate, and it certifies that the Internal Revenue Service (IRS) has issued a favorable determination letter (and the date thereof) that is currently in effect, what portion, if any, of the amounts paid constitute income includible under section 512 in computing the organization's unrelated business taxable income, and, if the organization is described in section 501(c)(3), whether it is a private foundation described in section 509. Notwithstanding the preceding sentence, if the organization cannot certify that it has been issued a favorable determination letter that is still in effect, its withholding certificate is nevertheless valid under this paragraph (b)(2) if the organization attaches to the withholding certificate an opinion that is acceptable to the withholding agent from a U.S. counsel (or any other person as the IRS may prescribe in published guidance (see 601.601(d)(2) of this chapter)) concluding that the organization is described in section 501(c). If the determination letter or opinion of counsel to which the withholding certificate refers concludes that the organization is described in section 501(c)(3), and the certificate further certifies that the organization is not a private foundation described in section 509, an affidavit of the organization setting forth sufficient facts concerning the operations and support of the organization for the Internal Revenue Service (IRS) to determine that such organization would be likely to qualify as an organization described in section 509(a)(1), (2), (3), or (4) must be attached to the withholding certificate. An organization that provides an opinion of U.S. counsel or an affidavit may provide the same opinion or affidavit to more than one withholding agent provided that the opinion is acceptable to each withholding agent who receives it in conjunction with a withholding certificate. Any such opinion of counsel or affidavit must be renewed whenever there is a change in facts or circumstances that are relevant to determine the organization's status under section 501(c) or, if relevant, that the organization is or is not a private foundation described in section 509. (3) Presumptions in the absence of documentation. Notwithstanding paragraph (b)(1) of this section, if the organization's certification with respect to whether amounts paid constitute income includable under section 512 in computing the organization's unrelated business taxable income is not reliable or is lacking but all other certifications are reliable, the withholding agent may rely on the certificate but the amounts paid are presumed to be income includable under section 512 in computing the organization's unrelated business taxable income. If the certification regarding private foundation status is not reliable, the withholding agent may rely on the certificate but the amounts paid are presumed to be paid to a foreign beneficial owner that is a private foundation. (4) Reason to know. Reliance by a withholding agent on the information and certifications stated on a withholding certificate is subject to the agent's actual knowledge or reason to know that such information or certification is incorrect as provided in 1.1441-7(b). For example, a withholding agent must cease to treat a foreign organization's claim for exemption from withholding based on the organization's tax-exempt status as valid beginning on the earlier of the date on which such agent knows that the IRS has given notice to such foreign organization that it is not an organization described in section 501(c) or the date on which the IRS gives notice to the public that such foreign organization is not an organization described in section 501(c). Similarly, a withholding agent may no longer rely on a certification that an amount is not subject to tax under section 4948 beginning on the earlier of the date on which such agent knows that the IRS has given notice to such foreign organization that it is subject to tax under section 4948 or the date on which the IRS gives notice that such foreign organization is a private foundation within the meaning of section 509(a).
