26 CFR § 1.1223-1 - Determination of period for which capital assets are held.
(a) The holding period of property received in an exchange by a taxpayer includes the period for which the property which he exchanged was held by him, if the property received has the same basis in whole or in part for determining gain or loss in the hands of the taxpayer as the property exchanged. However, this rule shall apply, in the case of exchanges after March 1, 1954, only if the property exchanged was at the time of the exchange a capital asset in the hands of the taxpayer or property used in his trade or business as defined in section 1231(b). For the purposes of this paragraph, the term exchange includes the following transactions:
(1) An involuntary conversion described in section 1033, and
(2) A distribution to which section 355 (or so much of section 356 as relates to section 355) applies.
(b) The holding period of property in the hands of a taxpayer shall include the period during which the property was held by any other person, if such property has the same basis in whole or in part in the hands of the taxpayer for determining gain or loss from a sale or exchange as it would have in the hands of such other person. For example, the period for which property acquired by gift after December 31, 1920, was held by the donor must be included in determining the period for which the property was held by the taxpayer if, under the provisions of section 1015, such property has, for the purpose of determining gain or loss from the sale or exchange, the same basis in the hands of the taxpayer as it would have in the hands of the donor. Similarly, the period for which property acquired from a decedent who died in 2010 was held by the decedent must be included in determining the period during which the property was held by the recipient, if the recipient's basis in the property is determined under section 1022.
(c) In determining the period for which the taxpayer has held stock or securities received upon a distribution where no gain was recognized to the distributee under section 1081(c) (or under section 112(g) of the Revenue Act of 1928 (45 Stat. 818) or the Revenue Act of 1932 (47 Stat. 197)), there shall be included the period for which he held the stock or securities in the distributing corporation before the receipt of the stock or securities on such distribution.
(d) If the acquisition of stock or securities resulted in the nondeductibility (under section 1091, relating to wash sales) of the loss from the sale or other disposition of substantially identical stock or securities, the holding period of the newly acquired securities shall include the period for which the taxpayer held the securities with respect to which the loss was not allowable.
(e) The period for which the taxpayer has held stock, or stock subscription rights, received on a distribution shall be determined as though the stock dividend, or stock right, as the case may be, were the stock in respect of which the dividend was issued if the basis for determining gain or loss upon the sale or other disposition of such stock dividend or stock right is determined under section 307. If the basis of stock received by a taxpayer pursuant to a spin-off is determined under so much of section 1052(c) as refers to section 113(a)(23) of the Internal Revenue Code of 1939, and such stock is sold or otherwise disposed of in a taxable year which is subject to the Internal Revenue Code of 1954, the period for which the taxpayer has held the stock received in such spin-off shall include the period for which he held the stock of the distributing corporation with respect to which such distribution was made.
(f) The period for which the taxpayer has held stock or securities issued to him by a corporation pursuant to the exercise by him of rights to acquire such stock or securities from the corporation will, in every case and whether or not the receipt of taxable gain was recognized in connection with the distribution of the rights, begin with and include the day upon which the rights to acquire such stock or securities were exercised. A taxpayer will be deemed to have exercised rights received from a corporation to acquire stock or securities therein where there is an expression of assent to the terms of such rights made by the taxpayer in the manner requested or authorized by the corporation.
(g) The period for which the taxpayer has held a residence, the acquisition of which resulted under the provisions of section 1034 in the nonrecognition of any part of the gain realized on the sale or exchange of another residence, shall include the period for which such other residence had been held as of the date of such sale or exchange. For purposes of this paragraph, the term sale or exchange includes an involuntary conversion occurring after December 31, 1950, and before January 1, 1954.
(h) If a taxpayer accepts delivery of a commodity in satisfaction of a commodity futures contract, the holding period of the commodity shall include the period for which the taxpayer held the commodity futures contract, if such futures contract was a capital asset in his hands.
(i) If shares of stock in a corporation are sold from lots purchased at different dates or at different prices and the identity of the lots cannot be determined, the rules prescribed by the regulations under section 1012 for determining the cost or other basis of such stocks so sold or transferred shall also apply for the purpose of determining the holding period of such stock.
(j) In the case of a person acquiring property, or to whom property passed, from a decedent (within the meaning of section 1014(b)) dying after December 31, 1970, such person shall be considered to have held the property for more than 1 year (6 months for taxable years beginning before 1977; 9 months for taxable years beginning in 1977) if the property:
(1) Has a basis in the hands of such person which is determined in whole or in part under section 1014, and
(2) Is sold or otherwise disposed of by such person within 6 months after the decedent's death.
(k) Any reference in section 1223 or this section to another provision of the Internal Revenue Code of 1954 is, where applicable, to be deemed a reference to the corresponding provision of the Internal Revenue Code of 1939, or prior internal revenue laws. The provisions of prior internal revenue laws here intended are the sections referred to in the sections of the Internal Revenue Code of 1939 which correspond to the sections of the Internal Revenue Code of 1954 referred to in section 1223. Thus, the sections corresponding to section 1081(c) are section 371(c) of the Revenue Act of 1938 (52 Stat. 553) and section 371(c) of the Internal Revenue Code of 1939. The sections corresponding to section 1091 are section 118 of each of the following: The Revenue Acts of 1928 (45 Stat. 826), 1932 (47 Stat. 208), 1934 (48 Stat. 715), 1936 (49 Stat. 1692), 1938 (52 Stat. 503), and the Internal Revenue Code of 1939.
