Sec. 1.1015-4 Transfers in part a gift and in part a sale.

(1) Whichever of the following is the greater:

(2) The amount of increase, if any, in basis authorized by section 1015(d) for gift tax paid (see section 1.1015-5). For determining loss, the unadjusted basis of the property in the hands of the transferee shall not be greater than the fair market value of the property at the time of such transfer. For determination of gain or loss of the transferor, see section 1.1001-1(e) and section 1.1011-2. For special rule where there has been a charitable contribution of less than a taxpayer's entire interest in property, see section 170(e)(2) and section 1.170A-4(c).

Example (1). If A transfers property to his son for $30,000, and such property at the time of the transfer has an adjusted basis of $30,000 in A's hands (and a fair market value of $60,000), the unadjusted basis of the property in the hands of the son is $30,000.

Example (2). If A transfers property to his son for $60,000, and such property at the time of transfer has an adjusted basis of $30,000 in A's hands (and a fair market value of $90,000), the unadjusted basis of such property in the hands of the son is $60,000.

Example (3). If A transfers property to his son for $30,000, and such property at the time of transfer has an adjusted basis in A's hands of $60,000 (and a fair market value of $90,000), the unadjusted basis of such property in the hands of the son is $60,000.

Example (4). If A transfers property to his son for $30,000 and such property at the time of transfer has an adjusted basis of $90,000 in A's hands (and a fair market value of $60,000), the unadjusted basis of the property in the hands of the son ins $90,000. However, since the adjusted basis of the property in A's hands at the time of the transfer was greater than the fair market value at that time, for the purpose of determining any loss on a later sale or other disposition of the property by the son its unadjusted basis in his hands is $60,000.
