In the case of any straddle which is an identified straddle—

Any loss with respect to 1 or more positions shall be taken into account for any taxable year only to the extent that the amount of such loss exceeds the unrecognized gain (if any) with respect to 1 or more positions which were offsetting positions with respect to 1 or more positions from which the loss arose.

(A) In general Any loss with respect to 1 or more positions shall be taken into account for any taxable year only to the extent that the amount of such loss exceeds the unrecognized gain (if any) with respect to 1 or more positions which were offsetting positions with respect to 1 or more positions from which the loss arose.

(B) Carryover of loss Any loss which may not be taken into account under subparagraph (A) for any taxable year shall, subject to the limitations under subparagraph (A), be treated as sustained in the succeeding taxable year.

In the case of any straddle which is an identified straddle—

(A) In generalIn the case of any straddle which is an identified straddle— (i) paragraph (1) shall not apply with respect to positions comprising the identified straddle, (ii) if there is any loss with respect to any position of the identified straddle, the basis of each of the offsetting positions in the identified straddle shall be increased by an amount which bears the same ratio to the loss as the unrecognized gain with respect to such offsetting position bears to the aggregate unrecognized gain with respect to all such offsetting positions, (iii) if the application of clause (ii) does not result in an increase in the basis of any offsetting position in the identified straddle, the basis of each of the offsetting positions in the identified straddle shall be increased in a manner which— (I) is reasonable, consistent with the purposes of this paragraph, and consistently applied by the taxpayer, and (II) results in an aggregate increase in the basis of such offsetting positions which is equal to the loss described in clause (ii), and (iv) any loss described in clause (ii) shall not otherwise be taken into account for purposes of this title.

(B) Identified straddleThe term “identified straddle” means any straddle— (i) which is clearly identified on the taxpayer’s records as an identified straddle before the earlier of— (I) the close of the day on which the straddle is acquired, or (II) such time as the Secretary may prescribe by regulations. (ii) to the extent provided by regulations, the value of each position of which (in the hands of the taxpayer immediately before the creation of the straddle) is not less than the basis of such position in the hands of the taxpayer at the time the straddle is created, and (iii) which is not part of a larger straddle. A straddle shall be treated as clearly identified for purposes of clause (i) only if such identification includes an identification of the positions in the straddle which are offsetting with respect to other positions in the straddle.

(C) Application to liabilities and obligations Except as otherwise provided by the Secretary, rules similar to the rules of clauses (ii) and (iii) of subparagraph (A) shall apply for purposes of this paragraph with respect to any position which is, or has been, a liability or obligation.

(B) Special rule for identified straddles For purposes of paragraph (2)(A)(ii), the unrecognized gain with respect to any offsetting position shall be the excess of the fair market value of the position at the time of the determination over the fair market value of the position at the time the taxpayer identified the position as a position in an identified straddle.

(ii) Reports not required in certain casesClause (i) shall not apply— (I) to any position which is part of an identified straddle, (II) to any position which, with respect to the taxpayer, is property described in paragraph (1) or (2) of section 1221(a) or to any position which is part of a hedging transaction (as defined in section 1256(e)), or (III) with respect to any taxable year if no loss on a position (including a regulated futures contract) has been sustained during such taxable year or if the only loss sustained on such position is a loss described in subclause (II).

(B) Limitation on net gain or net loss from mixed straddle accountIn the case of any mixed straddle account referred to in subparagraph (A)(i)(II)— (i) Not more than 50 percent of net gain may be treated as long-term capital gain In no event shall more than 50 percent of the net gain from such account for any taxable year be treated as long-term capital gain.
