(a)
In general— Section 1091 of the Internal Revenue Code of 1986 is amended to read as follows:
“1091. Loss from wash sales of specified assets
“(a) Disallowance of loss deduction
“(1) In general—No deduction shall be allowed with respect to any loss claimed to have been sustained from any sale or other disposition (including any termination) of specified assets where it appears that, within a period beginning 30 days before the date of such sale or other disposition and ending 30 days after such date, the taxpayer has—
“(A) acquired (by purchase, by an exchange on which the entire amount of gain or loss was recognized by law, or by entering into) substantially identical specified assets, or
“(B) entered into a contract or option to acquire, or notional principal contract in respect of, substantially identical specified assets.
“(2) Exception for dealers—Paragraph (1) shall not apply if—
“(A) the taxpayer is a dealer in specified assets,
“(B) the loss is sustained in a transaction made in the ordinary course of its business as a dealer, and
“(C) the acquisition (or the entering into of the contract or option to acquire or notional principal contract) which (without regard to this paragraph) would have resulted in the non-deductibility of the loss was similarly made in the ordinary course of such business.
“(3) Exception for stablecoins
“(A) In general—Except as otherwise provided by the Secretary, paragraph (1) shall not apply to a loss from the sale or disposition of a payment stablecoin or other stablecoin.
“(B) In general—Subject to subparagraph (C), for purposes of this paragraph, the term payment stablecoin means a digital asset—
“(i) that is, or is designed to be, used as a means of payment or settlement, and
“(ii) the issuer of which—
“(I) is obligated to convert, redeem, or repurchase for a fixed amount of monetary value (not including a digital asset denominated in a fixed amount of monetary value), and
“(II) represents that such issuer will maintain, or creates the reasonable expectation that such issuer will maintain, a stable value relative to the value of a fixed amount of monetary value.
“(C) Exception—The term payment stablecoin shall not include a digital asset that is—
“(i) a national currency,
“(ii) a deposit (as defined in section 3 of the Federal Deposit Insurance Act (12 U.S.C. 1813)), including a deposit recorded using distributed ledger technology, or
“(iii) a security, as defined in section 2 of the Securities Act of 1933 (15 U.S.C. 77b), section 3 of the Securities Exchange Act of 1934 (15 U.S.C. 78c), or section 2 of the Investment Company Act of 1940 (15 U.S.C. 80a–2).
“(b) Specified assets acquired less than specified assets sold—If the amount of specified assets acquired (or covered by the contract or option to acquire or notional principal contract) is less than the amount of specified assets sold or otherwise disposed of, then the particular specified assets the loss from the sale or other disposition of which is not deductible shall be determined under regulations prescribed by the Secretary.
“(c) Specified assets acquired not less than specified assets sold—If the amount of specified assets acquired (or covered by the contract or option to acquire or notional principal contract) is not less than the amount of specified assets sold or otherwise disposed of, then the particular specified assets the acquisition of which (or the entering into of the contract or option to acquire or notional principal contract of which) resulted in the non-deductibility of the loss shall be determined under regulations prescribed by the Secretary.
“(d) Adjustment to basis in case of wash sale
“(1) In general—The basis of the specified asset acquired (or the contract, option, or notional principal contract entered into) shall be increased by the amount of the deduction disallowed under subsection (a).
“(2) Rules with respect to certain acquisitions
“(A) In general—In any case in which—
“(i) the taxpayer enters into a contract or option to acquire, or notional principal contract in respect of, substantially identical specified assets (within the period specified in subsection (a)),
“(ii) the taxpayer also acquires (within the period specified in subsection (a)) substantially identical specified assets and such acquisition would, but for the entering into of the contract, option, or notional principal contract described in clause (i), have triggered a disallowance under subsection (a), and
“(iii) the contract, option, or notional principal contract matures, expires, is exercised, or otherwise terminates without the delivery or receipt of money or property during the term of the contract, option, or notional principal contract (other than at the time the contract, option, or notional principal contract is entered into) or upon such termination,
“(B) Special rule for contracts and options—Subject to such exceptions as the Secretary shall prescribe (including with respect to non-abusive wash sale basis adjustment practices), if the acquisition of any substantially identical specified asset is pursuant to a contract or option described in subparagraph (A)(i), then, notwithstanding whether such asset was acquired within the period specified in subsection (a), paragraph (1) shall apply to the substantially identical specified asset acquired pursuant to the contract or option and not to the contract or option.
“(e) Certain short sales of specified assets and contracts To sell—Rules similar to the rules of subsection (a) shall apply to any loss realized on the closing of a short sale of (or the sale, disposition, or termination of a contract or option to sell or a short notional principal contract in respect of) specified assets if, within a period beginning 30 days before the date of such closing and ending 30 days after such date, another such short sale of (or contract or option to sell or short notional principal contract in respect of) substantially identical specified assets was entered into by the taxpayer.
“(f) Cash settlement—This section shall not fail to apply to a contract or option to acquire or sell specified assets solely by reason of the fact that the contract or option settles in (or could be settled in) cash or property other than such specified assets.
“(g) Specified asset—For purposes of this section, the term specified asset means any of the following:
“(1) Any security (as defined in section 475(c)(2)), including contracts or options to acquire or sell securities.
“(2) Except as otherwise provided by the Secretary—
“(A) any digital asset,
“(B) any notional principal contract with respect to any digital asset described in subparagraph (A), and
“(C) any evidence of an interest in, or a derivative instrument in, any digital asset described in subparagraph (A) or (B), including any option, forward contract, futures contract, short position, and any similar instrument in such a digital asset.
“(h) Regulations—The Secretary may prescribe such regulations or other guidance as may be necessary to carry out the purposes of this section, including relating to abusive basis adjustment practices.”
