26 CFR § 1.691(c)-1 - Deduction for estate tax attributable to income in respect of a decedent.
(a) In general. A person who is required to include in gross income for any taxable year an amount of income in respect of a decedent may deduct for the same taxable year that portion of the estate tax imposed upon the decedent's estate which is attributable to the inclusion in the decedent's estate of the right to receive such amount. The deduction is determined as follows:
(1) Ascertain the net value in the decedent's estate of the items which are included under section 691 in computing gross income. This is the excess of the value included in the gross estate on account of the items of gross income in respect of the decedent (see § 1.691(a)-1 and paragraph (c) of this section) over the deductions from the gross estate for claims which represent the deductions and credit in respect of the decedent (see § 1.691(b)-1). But see section 691(d) and paragraph (b) of § 1.691(d)-1 for computation of the special value of a survivor's annuity to be used in computing the net value for estate tax purposes in cases involving joint and survivor annuities.
(2) Ascertain the portion of the estate tax attributable to the inclusion in the gross estate of such net value. This is the excess of the estate tax over the estate tax computed without including such net value in the gross estate. In computing the estate tax without including such net value in the gross estate, any estate tax deduction (such as the marital deduction) which may be based upon the gross estate shall be recomputed so as to take into account the exclusion of such net value from the gross estate. See example 2, paragraph (e) of § 1.691(d)-1.
(b) Prior decedent. If a person is required to include in gross income an amount of income in respect of a prior decedent, such person may deduct for the same taxable year that portion of the estate tax imposed upon the prior decedent's estate which is attributable to the inclusion in the prior decedent's estate of the value of the right to receive such amount. This deduction is computed in the same manner as provided in paragraph (a) of this section and is in addition to the deduction for estate tax imposed upon the decedent's estate which is attributable to the inclusion in the decedent's estate of the right to receive such amount.
(c) Amounts deemed to be income in respect of a decedent. For purposes of allowing the deduction under section 691(c), the following items are also considered to be income in respect of a decedent under section 691(a):
(1) The value for estate tax purposes of stock options in respect of which amounts are includible in gross income under section 421(b) (prior to amendment by section 221(a) of the Revenue Act of 1964), in the case of taxable years ending before January 1, 1964, or under section 422(c)(1), 423(c), or 424(c)(1), whichever is applicable, in the case of taxable years ending after December 31, 1963. See section 421(d)(6) (prior to amendment by sec. 221(a) of the Revenue Act of 1964), in the case of taxable years ending before January 1, 1964, and section 421(c)(2), in the case of taxable years ending after December 31, 1963.
(2) Amounts received by a surviving annuitant during his life expectancy period as an annuity under a joint and survivor annuity contract to the extent included in gross income under section 72. See section 691(d).
