(a) Section 691(a)(2) provides the rules governing the treatment of income in respect of a decedent (or a prior decedent) in the event a right to receive such income is transferred by the estate or person entitled thereto by bequest, devise, or inheritance, or by reason of the death of the decedent. In general, the transferor must include in his gross income for the taxable period in which the transfer occurs the amount of the consideration, if any, received for the right or the fair market value of the right at the time of the transfer, whichever is greater. Thus, upon a sale of such right by the estate or person entitled to receive it, the fair market value of the right or the amount received upon the sale, whichever is greater, is included in the gross income of the vendor. Similarly, if such right is disposed of by gift, the fair market value of the right at the time of the gift must be included in the gross income of the donor. In the case of a satisfaction of an installment obligation at other than face value, which is likewise considered a transfer under section 691(a)(2), see § 1.691(a)-5.
(b) If the estate of a decedent or any person transmits the right to income in respect of a decedent to another who would be required by section 691(a)(1) to include such income when received in his gross income, only the transferee will include such income when received in his gross income. In this situation, a transfer within the meaning of section 691(a)(2) has not occurred. This paragraph may be illustrated by the following:
(1) If a person entitled to income in respect of a decedent dies before receiving such income, only his estate or other person entitled to such income by bequest, devise, or inheritance from the latter decedent, or by reason of the death of the latter decedent, must include such amount in gross income when received.
(2) If a right to income in respect of a decedent is transferred by an estate to a specific or residuary legatee, only the specific or residuary legatee must include such income in gross income when received.
(3) If a trust to which is bequeathed a right of a decedent to certain payments of income terminates and transfers the right to a beneficiary, only the beneficiary must include such income in gross income when received.
If the transferee described in subparagraphs (1), (2), and (3) of this paragraph transfers his right to receive the amounts in the manner described in paragraph (a) of this section, the principles contained in paragraph (a) are applied to such transfer. On the other hand, if the transferee transmits his right in the manner described in this paragraph, the principles of this paragraph are again applied to such transfer.
