TREASURY REGULATIONS

(a) Sections 503(e) and 681(b)(5) provides that no deduction which would otherwise be allowable under section 2055 for the value of property transferred by the decedent during his lifetime or by will for religious, charitable, scientific, literary, or educational purposes (including the encouragement of art and the prevention of cruelty to children or animals) is allowed if (1) the transfer is made in trust, and, for income tax purposes for the taxable year of the trust in which the transfer is made, the deduction otherwise allowable to the trust under section 642(c) is limited by section 681(b)(1) by reason of the trust having engaged in a prohibited transaction described in section 681(b)(2), or (2) the transfer is made to a corporation, community chest, fund or foundation which, for its taxable year in which the transfer is made, is not exempt from income tax under section 501(a) by reason of having engaged in a prohibited transaction described in section 503(c).

(b) For purposes of section 681(b)(5) and section 503(e), the term “transfer” includes any gift, contribution, bequest, devise, legacy, or other disposition. In applying such sections for estate tax purposes, a transfer, whether made during the decedent's lifetime or by will, is considered as having been made at the moment of the decedent's death.

(c) The income tax regulations contain the rules for the determination of the taxable year of the trust for which the deduction under section 642(c) is limited by section 681(b) and for the determination of the taxable year of the organization for which an exemption is denied under section 503(a). Generally, such taxable year is a taxable year subsequent to the taxable year during which the trust or organization has been notified by the Commissioner of Internal Revenue that it has engaged in a prohibited transaction. However, if the trust or organization during or prior to the taxable year entered into the prohibited transaction for the purpose of diverting its corpus or income from the charitable or other purposes by reason of which it is entitled to a deduction or exemption, and the transaction involves a substantial part of the income or corpus, then the deduction of the trust under section 642(c) for such taxable year is limited by section 681(b), or exemption of the organization for such taxable year is denied under section 503(a), whether or not the organization has previously received notification by the Commissioner of Internal Revenue that it is engaged in a prohibited transaction. In certain cases, the limitation of section 681 or 503 may be removed or the exemption may be reinstated for certain subsequent taxable years under the rules set forth in the income tax regulations under sections 681 and 503. In cases in which prior notification by the Commissioner of Internal Revenue is not required in order to limit the deduction of the trust under section 681(d) or to deny exemption of the organization under section 503, the deduction otherwise allowable under section 2055 is not disallowed in respect of transfers made during the same taxable year of the trust or organization in which a prohibited transaction occurred or in a prior taxable year unless the decedent or a member of his family was a party to the prohibited transaction. For the purpose of the preceding sentence, the members of the decedent's family include only his brothers and sisters, whether by whole or half blood, spouse, ancestors, and lineal descendants.

(d) This section applies only in the case of decedents dying before January 1, 1970. In the case of decedents dying after December 31, 1969, see § 20.2055-5.
