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.

Code of Federal Regulations

For purposes of this section, the term estate tax means the tax imposed under section 2001 or 2101 (or the corresponding provisions of the Internal Revenue Code of 1939), reduced by the credits against such tax. Each person including in gross income an amount of income in respect of a decedent may deduct as his share of the portion of the estate tax (computed under subparagraph (2) of this paragraph) an amount which bears the same ratio to such portion as the value in the gross estate of the right to the income included by such person in gross income (or the amount included in gross income if lower) bears to the value in the gross estate of all the items of gross income in respect of the decedent.
(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).
(d) Examples. Paragraphs (a) and (b) of this section may be illustrated by the following examples:

Code of Federal Regulations

Example 1. X, an attorney who kept his books by use of the cash receipts and disbursements method, was entitled at the date of his death to a fee for services rendered in a case not completed at the time of his death, which fee was valued in his estate at $1,000, and to accrued bond interest, which was valued in his estate at $500. In all, $1,500 was included in his gross estate in respect of income described in section 691(a)(1). There were deducted as claims against his estate $150 for business expenses for which his estate was liable and $50 for taxes accrued on certain property which he owned. In all, $200 was deducted for claims which represent amounts described in section 691(b) which are allowable as deductions to his estate or to the beneficiaries of his estate. His gross estate was $185,000 and, considering deductions of $15,000 and an exemption of $60,000, his taxable estate amounted to $110,000. The estate tax on this amount is $23,700 from which is subtracted a $75 credit for State death taxes leaving an estate tax liability of $23,625. In the year following the closing of X's estate, the fee in the amount of $1,200 was collected by X's son, who was the sole beneficiary of the estate. This amount was included under section 691(a)(1)(C) in the son's gross income. The son may deduct, in computing his taxable income for such year, $260 on account of the estate tax attributable to such income, computed as follows:
(1) (i) Value of income described in section 691(a)(1) included in computing gross estate $1,500
(ii) Deductions in computing gross estate for claims representing deductions described in section 691(b) 200
(iii) Net value of items described in section 691(a)(1) 1,300
(2) (i) Estate tax 23,625
(ii) Less: Estate tax computed without including $1,300 (item (1)(iii)) in gross estate 23,235
(iii) Portion of estate tax attributable to net value of items described in section 691(a)(1) 390
(3) (i) Value in gross estate of items described in section 691(a)(1) received in taxable year (fee) 1,000
(ii) Value in gross estate of all income items described in section 691(a)(1) (item (1)(i)) 1,500
(iii) Part of estate tax deductible on account of receipt of $1,200 fee (1,000/1,500 of $390) 260
Although $1,200 was later collected as the fee, only the $1,000 actually included in the gross estate is used in the above computations. However, to avoid distortion, section 691(c) provides that if the value included in the gross estate is greater than the amount finally collected, only the amount collected shall be used in the above computations. Thus, if the amount collected as the fee were only $500, the estate tax deductible on the receipt of such amount would be 500/1,500 of $390, or $130. With respect to taxable years ending before January 1, 1964, see paragraph (d)(3) of § 1.421-5 for a similar example involving a restricted stock option. With respect to taxable years ending after December 31, 1963, see paragraph (c)(3) of § 1.421-8 for a similar example involving a stock option subject to the provisions of part II of subchapter D.

Code of Federal Regulations

Example 2. Assume that in example 1 the fee valued at $1,000 had been earned by prior decedent Y and had been inherited by X who died before collecting it. With regard to the son, the fee would be considered income in respect of a prior decedent. Assume further that the fee was valued at $1,000 in Y's estate, that the net value in Y's estate of items described in section 691 (a)(1) was $5,000 and that the estate tax imposed on Y's estate attributable to such net value was $550. In such case, the portion of such estate tax attributable to the fee would be 1,000/5,000 of $550, or $110. When the son collects the $1,200 fee, he will receive for the same taxable year a deduction of $110 with respect to the estate tax imposed on the estate of prior decedent Y as well as the deduction of $260 (as computed in example 1) with respect to the estate tax imposed on the estate of decedent X.
