26 CFR § 1.1015-1 - Basis of property acquired by gift after December 31, 1920.
(a) General rule.
(1) In the case of property acquired by gift after December 31, 1920 (whether by a transfer in trust or otherwise), the basis of the property for the purpose of determining gain is the same as it would be in the hands of the donor or the last preceding owner by whom it was not acquired by gift. The same rule applies in determining loss unless the basis (adjusted for the period prior to the date of gift in accordance with sections 1016 and 1017) is greater than the fair market value of the property at the time of the gift. In such case, the basis for determining loss is the fair market value at the time of the gift.
(2) The provisions of subparagraph (1) of this paragraph may be illustrated by the following example.
(3) If the facts necessary to determine the basis of property in the hands of the donor or the last preceding owner by whom it was not acquired by gift are unknown to the donee, the district director shall, if possible, obtain such facts from such donor or last preceding owner, or any other person cognizant thereof. If the district director finds it impossible to obtain such facts, the basis in the hands of such donor or last preceding owner shall be the fair market value of such property as found by the district director as of the date or approximate date at which, according to the best information the district director is able to obtain, such property was acquired by such donor or last preceding owner. See paragraph (e) of this section for rules relating to fair market value.
(b) Uniform basis; proportionate parts of. Property acquired by gift has a single or uniform basis although more than one person may acquire an interest in such property. The uniform basis of the property remains fixed subject to proper adjustment for items under sections 1016 and 1017. However, the value of the proportionate parts of the uniform basis represented, for instance, by the respective interests of the life tenant and remainderman are adjustable to reflect the change in the relative values of such interest on account of the lapse of time. The portion of the basis attributable to an interest at the time of its sale or other disposition shall be determined under the rules provided in § 1.1014-5. In determining gain or loss from the sale or other disposition after October 9, 1969, of a term interest in property (as defined in § 1.1001-1(f)(2)) the adjusted basis of which is determined pursuant, or by reference, to section 1015, that part of the adjusted uniform basis assignable under the rules of § 1.1014-5(a) to the interest sold or otherwise disposed of shall be disregarded to the extent and in the manner provided by section 1001(e) and § 1.1001-1(f).
(c) Time of acquisition. The date that the donee acquires an interest in property by gift is when the donor relinquishes dominion over the property and not necessarily when title to the property is acquired by the donee. Thus, the date that the donee acquires an interest in property by gift where he is a successor in interest, such as in the case of a remainderman of a life estate or a beneficiary of the distribution of the corpus of a trust, is the date such interests are created by the donor and not the date the property is actually acquired.
(d) Property acquired by gift from a decedent dying after December 31, 1953. If an interest in property was acquired by the taxpayer by gift from a donor dying after December 31, 1953, under conditions which required the inclusion of the property in the donor's gross estate for estate tax purposes, and the property had not been sold, exchanged, or otherwise disposed of by the taxpayer before the donor's death, see the rules prescribed in section 1014 and the regulations thereunder.
(e) Fair market value. For the purposes of this section, the value of property as appraised for the purpose of the Federal gift tax, or, if the gift is not subject to such tax, its value as appraised for the purpose of a State gift tax, shall be deemed to be the fair market value of the property at the time of the gift.
(f) Reinvestments by fiduciary. If the property is an investment by the fiduciary under the terms of the gift (as, for example, in the case of a sale by the fiduciary of property transferred under the terms of the gift, and the reinvestment of the proceeds), the cost or other basis to the fiduciary is taken in lieu of the basis specified in paragraph (a) of this section.
(g) Records. To insure a fair and adequate determination of the proper basis under section 1015, persons making or receiving gifts of property should preserve and keep accessible a record of the facts necessary to determine the cost of the property and, if pertinent, its fair market value as of March 1, 1913, or its fair market value as of the date of the gift.
