Reportable barter exchanges and gross proceeds of sales of securities, commodities, or digital assets by brokers

(ii) Rules concerning withdrawals. A withdrawal includes the use of money (including both gross proceeds and variation margin) or property in the account to purchase any property other than property acquired in connection with the closing of a contract. For this purpose, the acceptance of a warehouse receipt or other taking of delivery to close a contract is in connection with the closing of a contract only if the property acquired is disposed of by the close of the seventh trading day following the trading day that the customer takes delivery under the contract. In addition, making delivery to close a contract is in connection with the closing of a contract only if the broker is able to determine that the property used to close the contract was acquired no earlier than the seventh trading day prior to the trading day on which delivery is made. Withdrawals do not include repayments of debt incurred in connection with making or taking delivery that meets the requirements of this paragraph (b)(2). Withdrawals also do not include payments of commissions, fees, transfers of cash from the account to another futures account that is subject to this paragraph (b)(2) or cash withdrawals traceable to dispositions of property other than futures (not including profit on the contract separately reportable under § 1.6045-1(c)(5)(i)(b) of this chapter).

(iii) Special rule for forward contracts, including foreign currency contracts, and regulated futures contracts. The determination of whether the customer is subject to withholding under section 3406 with respect to an account containing forward contracts, including foreign currency contracts, or regulated futures contracts must be made at the time of the cash or property withdrawals or the relevant year-end, whichever is applicable.

(3) Security sales made through a margin account. The amount described in paragraph (a) of this section that is subject to withholding under section 3406 in the case of a security sale made through a margin account (as defined in 12 CFR part 220 (Regulation T)) is the gross proceeds (as defined in § 1.6045-1(d)(5) of this chapter) of the sale. The amount required to be withheld with respect to the sale, however, is limited to the amount of cash available for withdrawal by the customer immediately after the settlement of the sale. For this purpose, the amount available for withdrawal by the customer does not include amounts required to satisfy margin maintenance under Regulation T, rules and regulations of the National Association of Securities Dealers and national securities exchanges, and generally applicable self-imposed rules of the margin account carrier.

(4) Security short sales—(i) Amount subject to backup withholding. The amount subject to withholding under section 3406 with respect to a short sale of securities is the gross proceeds (as defined in § 1.6045-1(d)(5) of this chapter) of the short sale. At the option of the broker, however, the amount subject to withholding may be the gain upon the closing of the short sale (if any); consequently, the obligation to withhold under section 3406 would be deferred until the closing transaction. A broker may use this alternative method of determining the amount subject to withholding under section 3406 with respect to a short sale only if at the time the short sale is initiated, the broker expects that the amount of gain realized upon the closing of the short sale will be determinable from the broker's records. If, due to events unforeseen at the time the short sale was initiated, the broker is unable to determine the basis of the property used to close the short sale, the property must be assumed for this purpose to have a basis of zero.

(ii) Time of backup withholding. The determination of whether a short seller is subject to withholding under section 3406 must be made on the date of the initiation or closing, as the case may be, or on the date that the initiation or closing, as the case may be, is entered on the broker's books and records.

(5) Fractional shares. A broker is not required to withhold under section 3406 with respect to a sale of a fractional share of stock resulting in less than $20 of gross proceeds (as described in § 1.6045-1(c)(3)(x) of this chapter).

(6) Amount subject to backup withholding in the case of reporting under § 1.6045-1(d)(2)(i)(C) and (d)(10) of this chapter—(i) Optional reporting method for sales of qualifying stablecoins and specified nonfungible tokens—(A) In general. The amount subject to withholding under section 3406 for a broker that reports sales of digital assets under the optional method for reporting qualifying stablecoins or specified nonfungible tokens under § 1.6045-1(d)(10) of this chapter is the amount of gross proceeds from designated sales of qualifying stablecoins as defined in § 1.6045-1(d)(10)(i)(C) of this chapter and sales of specified nonfungible tokens without regard to the amount which must be paid to the broker's customer before reporting is required.

(B) Backup withholding on non-designated sales of qualifying stablecoins—(1) In general. A broker is not required to withhold under section 3406 on non-designated sales of qualifying stablecoins as defined under § 1.6045-1(d)(10)(i)(C) of this chapter.

(2) Non-qualifying events. In the case of a digital asset that would satisfy the definition of a non-designated sale of a qualifying stablecoin as defined under § 1.6045-1(d)(10)(i)(C) of this chapter for a calendar year but for a non-qualifying event during that year, a broker is not required to withhold under section 3406 on such sale if it occurs no later than the end of the day that is 30 days after the first non-qualifying event with respect to such digital asset during such year. A non-qualifying event is the first date during a calendar year on which the digital asset no longer satisfies all three conditions described in § 1.6045-1(d)(10)(ii)(A) through (C) of this chapter to be a qualifying stablecoin. For purposes of this paragraph (b)(6)(i)(B)(2), the date on which a non-qualifying event has occurred with respect to a digital asset and the date that is no later than 30 days after such non-qualifying event must be determined using Coordinated Universal Time (UTC).

(ii) Applicable threshold for sales by processors of digital asset payments. For purposes of determining the amount subject to withholding under section 3406, the amount subject to reporting under section 6045 is determined without regard to the minimum gross proceeds which must be paid to the customer under § 1.6045-1(d)(2)(i)(C) of this chapter before reporting is required.

(c) Applicability date. This section applies to reportable payments made on or after January 1, 2025. For the rules applicable to reportable payments made prior to January 1, 2025, see § 31.3406(b)(3)-2 in effect and contained in 26 CFR part 1 revised April 1, 2024.
