Confidentiality of information.

# (b)

Permissible use of information—(1) In general. A payor or broker may transmit information on a Form W-9, Form W-8, or other acceptable form relating to withholding to the department, institution, or firm (or to any employee therein) responsible for withholding or processing of taxpayer identification numbers, certifications described in § 31.3406(h)-3, or other substitute forms. In addition, a broker may notify the payor with respect to a readily tradable instrument of the requirement to withhold and the condition or conditions for imposing withholding (as described in § 31.3406(d)-4) that exist with respect to the payee. A payor or broker may, without violating the Internal Revenue Code, close an account of, refuse to open an account for, issue an instrument to, or redeem an instrument for, a person solely because the person fails to furnish the person's taxpayer identification number or documentation of foreign status in the manner required in § 31.3406(d)-1 and § 31.3406(g)-1, respectively. A payor who closes an account of a payee in the calendar year in which the account was opened and during which no taxpayer identification number or evidence of foreign status was provided for that account will be presumed in the absence of evidence to the contrary to have closed the account without violating section 3406(f) even though the payee is subject to backup withholding under section 3406(a)(1)(A). A payor, except as provided in §§ 31.3406(d)-3 and 31.3406(g)-3, may not prohibit a payee who fails to furnish the payee's taxpayer identification number in the manner required in § 31.3406(d)-1 from withdrawing any funds in the account.

(2) Window transactions. In the case of a window transaction (as defined in § 31.3406(b)(2)-3(b)), a payor may, without violating the Internal Revenue Code, refuse to redeem or may refuse to make payment if the payee fails to provide a taxpayer identification number regardless of when the obligation was issued or acquired.
