26 CFR § 20.2207A-1 - Right of recovery of estate taxes in the case of certain marital deduction property.
(a) In general -
(1) Right of recovery from person receiving the property. If the gross estate includes the value of property that is includible by reason of section 2044 (relating to certain property in which the decedent had a qualifying income interest for life under sections 2056(b)(7) or 2523(f)), the estate of the surviving spouse is entitled to recover from the person receiving the property (as defined in paragraph (d) of this section) the amount of Federal estate tax attributable to that property. The right of recovery arises when the Federal estate tax with respect to the property includible in the gross estate by reason of section 2044 is paid by the estate. There is no right of recovery from any person for the property received by that person for which a deduction was allowed from the gross estate if no tax is attributable to that property.
(2) Failure to exercise right of recovery. Failure of an estate to exercise a right of recovery under this section upon a transfer subject to section 2044 is treated as a transfer for Federal gift tax purposes of the unrecovered amounts from the persons who would benefit from the recovery to the persons from whom the recovery could have been obtained. See § 25.2511-1 of this chapter. The transfer is considered made when the right of recovery is no longer enforceable under applicable law. A delay in the exercise of the right of recovery without payment of sufficient interest is a below-market loan. Section 1.7872-5T of the Temporary Income Tax regulations describes factors that are used to determine, based on the facts and circumstances of a particular case, whether a loan otherwise subject to imputation under section 7872 (relating to the treatment of below-market loans) is exempted from its provisions.
(3) Waiver of right of recovery. The provisions of § 20.2207A-1(a)(2) do not apply to the extent that the surviving spouse's will provides that a recovery shall not be made or to the extent that the beneficiaries cannot otherwise compel recovery. Thus, e.g., if the surviving spouse gives the executor of the estate discretion to waive the right of recovery and the executor waives the right, no gift occurs under § 25.2511-1 of this chapter if the persons who would benefit from the recovery cannot compel the executor to exercise the right of recovery.
(b) Amount of estate tax attributable to property includible under section 2044. The amount of Federal estate tax attributable to property includible in the gross estate under section 2044 is the amount by which the total Federal estate tax (including penalties and interest attributable to the tax) under chapter 11 of the Internal Revenue Code that has been paid, exceeds the total Federal estate tax (including penalties and interest attributable to the tax) under chapter 11 of the Internal Revenue Code that would have been paid if the value of the property includible in the gross estate by reason of section 2044 had not been so included.
(c) Amount of estate tax attributable to a particular property. An estate's right of recovery with respect to a particular property is an amount equal to the amount determined in paragraph (b) of this section multiplied by a fraction. The numerator of the fraction is the value for Federal estate tax purposes of the particular property included in the gross estate by reason of section 2044, less any deduction allowed with respect to the property. The denominator of the fraction is the total value of all properties included in the gross estate by reason of section 2044, less any deductions allowed with respect to those properties.
(d) Person receiving the property. If the property is in a trust at the time of the decedent's death, the person receiving the property is the trustee and any person who has received a distribution of the property prior to the expiration of the right of recovery if the property does not remain in trust. This paragraph (d) does not affect the right, if any, under local law, of any person with an interest in property to reimbursement or contribution from another person with an interest in the property.
(e) Example. The following example illustrates the application of paragraphs (a) through (d) of this section.
