(a) In general. Section 2523(e) provides that if an interest in property is transferred by a donor to his spouse (whether or not in trust) and the spouse is entitled for life to all the income from a specific portion of the entire interest, with a power in her to appoint the entire interest of all the income from interest or the specific portion, the interest transferred to her is a deductible interest, to the extent that it satisfies all five of the conditions set forth below (see paragraph (b) of this section if one or more of the conditions is satisfied as to only a portion of the interest):

(1) The donee spouse must be entitled for life to all of the income from the entire interest or a specific portion of the entire interest, or to a specific portion of all the income from the entire interest.

(2) The income payable to the donee spouse must be payable annually or at more frequent intervals.

(3) The donee spouse must have the power to appoint the entire interest of the specific portion to either herself or her estate.

(4) The power in the donee spouse must be exercisable by her alone and (whether exercisable by will or during life) must be exercisable in all events.

(5) The entire interest or the specific portion must not be subject to a power in any other person to appoint any part to any person other than the donee spouse.

(b) Specific portion; deductible amount. If either the right to income or the power of appointment given to the donee spouse pertains only to a specific portion of a property interest, the portion of the interest which qualifies as a deductible interest is limited to the extent that the rights in the donee spouse meet all of the five conditions described in paragraph (a) of this section. While the rights over the income and the power must coexist as to the same interest in property, it is not necessary that the rights over the income or the power as to such interest be in the same proportion. However, if the rights over income meeting the required conditions set forth in paragraph (a) (1) and (2) of this section extend over a smaller share of the property interest than the share with respect to which the power of appointment requirements set forth in paragraph (a) (3) through (5) of this section are satisfied, the deductible interest is limited to the smaller share. Conversely, if a power of appointment meeting all the requirements extends to a smaller portion of the property interest than the portion over which the income rights pertain, the deductible interest cannot exceed the value of the portion to which such power of appointment applies. Thus, if the donor gives to the donee spouse the right to receive annually all of the income from a particular property interest and a power of appointment meeting the specifications prescribed in paragraph (a) (3) through (5) of this section as to only one-half of the property interest, then only one-half of the property interest is treated as a deductible interest. Correspondingly, if the income interest of the spouse satisfying the requirements extends to only one-fourth of the property interest and a testamentary power of appointment satisfying the requirements extends to all of the property interest, then only one-fourth of the interest in the spouse qualifies as a deductible interest. Further, if the donee spouse has no right to income from a specific portion of a property interest but a testamentary power of appointment which meets the necessary conditions over the entire interest, then none of the interest qualifies for the deduction. In addition, if, from the time of the transfer, the donee spouse has a power of appointment meeting all of the required conditions over three-fourths of the entire property interest and the prescribed income rights over the entire interest, but with a power in another person to appoint one-half of the entire interest, the value of the interest in the donee spouse over only one-half of the property interest will qualify as a deductible interest.

(c) Meaning of specific portion—(1) In general. Except as provided in paragraphs (c)(2) and (c)(3) of this section, a partial interest in property is not treated as a specific portion of the entire interest. In addition, any specific portion of an entire interest in property is nondeductible to the extent the specific portion is subject to invasion for the benefit of any person other than the donee spouse, except in the case of a deduction allowable under section 2523(e), relating to the exercise of a general power of appointment by the donee spouse.

(2) Fraction or percentage share. Under section 2523(e), a partial interest in property is treated as a specific portion of the entire interest if the rights of the donee spouse in income, and the required rights as to the power described in §25.2523(e)-1(a), constitute a fractional or percentage share of the entire property interest, so that the donee spouse's interest reflects its proportionate share of the increase or decrease in the value of the entire property interest to which the income rights and the power relate. Thus, if the spouse's right to income and the spouse's power extend to a specified fraction or percentage of the property, or its equivalent, the interest is in a specific portion of the property. In accordance with paragraph (b) of this section, if the spouse has the right to receive the income from a specific portion of the trust property (after applying paragraph (c)(3) of this section) but has a power of appointment over a different specific portion of the property (after applying paragraph (c)(3) of this section), the marital deduction is limited to the lesser specific portion.

(3) Special rule in the case of gifts made on or before October 24, 1992. In the case of gifts within the purview of the effective date rule contained in paragraph (c)(3)(iii) of this section:

(i) A specific sum payable annually, or at more frequent intervals, out of the property and its income that is not limited by the income of the property is treated as the right to receive the income from a specific portion of the property. The specific portion, for purposes of paragraph (c)(2) of this section, is the portion of the property that, assuming the interest rate generally applicable for the valuation of annuities at the time of the donor's gift, would produce income equal to such payments. However, a pecuniary amount payable annually to a donee spouse is not treated as a right to the income from a specific portion of trust property for purposes of this paragraph (c)(3)(i) if any person other than the donee spouse may receive, during the donee spouse's lifetime, any distribution of the property. To determine the applicable interest rate for valuing annuities, see sections 2512 and 7520 and the regulations under those sections.

(ii) The right to appoint a pecuniary amount out of a larger fund (or trust corpus) is considered the right to appoint a specific portion of such fund or trust in an amount equal to such pecuniary amount.

(iii) The rules contained in paragraphs (c)(3) (i) and (ii) of this section apply with respect to gifts made on or before October 24, 1992.

(4) Local law. A partial interest in property is treated as a specific portion of the entire interest if it is shown that the donee spouse has rights under local law that are identical to those the donee spouse would have acquired had the partial interest been expressed in terms satisfying the requirements of paragraph (c)(2) of this section (or paragraph (c)(3) of this section if applicable).

(5) Examples. The following examples illustrate the application of paragraphs (b) and (c) of this section, where D, the donor, transfers property to D's spouse, S:

(d) Definition of “entire interest”. Since a marital deduction is allowed for each qualifying separate interest in property transferred by the donor to the donee spouse, for purposes of paragraphs (a) and (b) of this section, each property interest with respect to which the donee spouse received some rights is considered separately in determining whether her rights extend to the entire interest or to a specific portion of the entire interest. A property interest which consists of several identical units of property (such as a block of 250 shares of stock, whether the ownership is evidenced by one or several certificates) is considered one property interest, unless certain of the units are to be segregated and accorded different treatment, in which case each segregated group of items is considered a separate property interest. The bequest of a specified sum of money constitutes the bequest of a separate property interest if immediately following the transfer and thenceforth it, and the investments made with it, must be so segregated or accounted for as to permit its identification as a separate item of property. The application of this paragraph may be illustrated by the following examples:

(e) Application of local law. In determining whether or not the conditions set forth in paragraphs (a) (1) through (5) of this section are satisfied by the instrument of transfer, regard is to be had to the applicable provisions of the law of the jurisdiction under which the interest passes and, if the transfer is in trust, the applicable provisions of the law governing the administration of the trust. For example, silence of a trust instrument as to the frequency of payment will not be regarded as a failure to satisfy the condition set forth in paragraph (a)(2) of this section that income must be payable to the donee spouse annually or more frequently unless the applicable law permits payment to be made less frequently than annually. The principles outlined in this paragraph and paragraphs (f) and (g) of this section which are applied in determining whether transfers in trust meet such conditions are equally applicable in ascertaining whether, in the case of interests not in trust, the donee spouse has the equivalent in rights over income and over the property.

(f) Right to income.

(1) If an interest is transferred in trust, the donee spouse is “entitled for life to all of the income from the entire interest or a specific portion of the entire interest,” for the purpose of the condition set forth in paragraph (a)(1) of this section, if the effect of the trust is to give her substantially that degree of beneficial enjoyment of the trust property during her life which the principles of the law of trust accord to a person who is unqualifiedly designated as the life beneficiary of a trust. Such degree of enjoyment is given only if it was the donor's intention, as manifested by the terms of the trust instrument and the surrounding circumstances, that the trust should produce for the donee spouse during her life such an income, or that the spouse should have such use of the trust property as is consistent with the value of the trust corpus and with its preservation. The designation of the spouse as sole income beneficiary for life of the entire interest or a specific portion of the entire interest will be sufficient to qualify the trust unless the terms of the trust and the surrounding circumstances considered as a whole evidence an intention to deprive the spouse of the requisite degree of enjoyment. In determining whether a trust evidences that intention, the treatment required or permitted with respect to individual items must be considered in relation to the entire system provided for the administration of the trust. In addition, the spouse's interest shall meet the condition set forth in paragraph (a)(1) of this section if the spouse is entitled to income as defined or determined by applicable local law that provides for a reasonable apportionment between the income and remainder beneficiaries of the total return of the trust and that meets the requirements of §1.643(b)-1 of this chapter.

(2) If the over-all effect of a trust is to give to the donee spouse such enforceable rights as will preserve to her the requisite degree of enjoyment, it is immaterial whether that result is effected by rules specifically stated in the trust instrument, or, in their absence, by the rules for the management of the trust property and the allocation of receipts and expenditures supplied by the State law. For example, a provision in the trust instrument for amortization of bond premium by appropriate periodic charges to interest will not disqualify the interest transferred in trust even though there is no State law specifically authorizing amortization or there is a State law denying amortization which is applicable only in the absence of such a provision in the trust instrument.

(3) In the case of a trust, the rules to be applied by the trustee in allocation of receipts and expenses between income and corpus must be considered in relation to the nature and expected productivity of the assets transferred in trust, the nature and frequency of occurrence of the expected receipts, and any provisions as to change in the form of investments. If it is evident from the nature of the trust assets and the rules provided for management of the trust that the allocation to income of such receipts as rents, ordinary cash dividends and interest will give to the spouse the substantial enjoyment during life required by the statute, provisions that such receipts as stock dividends and proceeds from the conversion of trust assets shall be treated as corpus will not disqualify the interest transferred in trust. Similarly, provision for a depletion charge against income in the case of trust assets which are subject to depletion will not disqualify the interest transferred in trust, unless the effect is to deprive the spouse of the requisite beneficial enjoyment. The same principle is applicable in the case of depreciation, trustees' commissions, and other charges.

(4) Provisions granting administrative powers to the trustees will not have the effect of disqualifying an interest transferred in trust unless the grant of powers evidences the intention to deprive the donee spouse of the beneficial enjoyment required by the statute. Such an intention will not be considered to exist if the entire terms of the instrument are such that the local courts will impose reasonable limitations upon the exercise of the powers. Among the powers which if subject to reasonable limitations will not disqualify the interest transferred in trust are the power to determine the allocation or apportionment of receipts and disbursements between income and corpus, the power to apply the income or corpus for the benefit of the spouse, and the power to retain the assets transferred to the trust. For example, a power to retain trust assets which consist substantially of unproductive property will not disqualify the interest if the applicable rules for the administration of the trust require, or permit the spouse to require, that the trustee either make the property productive or convert it within a reasonable time. Nor will such a power disqualify the interest if the applicable rules for administration of the trust require the trustee to use the degree of judgment and care in the exercise of the power which a prudent man would use if he were owner of the trust assets. Further, a power to retain a residence for the spouse or other property for the personal use of the spouse will not disqualify the interest transferred in trust.

(5) An interest transferred in trust will not satisfy the condition set forth in paragraph (a)(1) of this section that the donee spouse be entitled to all the income if the primary purpose of the trust is to safeguard property without providing the spouse with the required beneficial enjoyment. Such trusts include not only trusts which expressly provide for the accumulation of the income but also trusts which indirectly accomplish a similar purpose. For example, assume that the corpus of a trust consists substantially of property which is not likely to be income producing during the life of the donee spouse and that the spouse cannot compel the trustee to convert or otherwise deal with the property as described in subparagraph (4) of this paragraph. An interest transferred to such a trust will not qualify unless the applicable rules for the administration require, or permit the spouse to require, that the trustee provide the required beneficial enjoyment, such as by payments to the spouse out of other assets of the trust.

(6) If a trust may be terminated during the life of the donee spouse, under her exercise of a power of appointment or by distribution of the corpus to her, the interest transferred in trust satisfies the condition set forth in paragraph (a)(1) of this section (that the spouse be entitled to all the income) if she (i) is entitled to the income until the trust terminates, or (ii) has the right, exercisable in all events, to have the corpus distributed to her at any time during her life.

(7) An interest transferred in trust fails to satisfy the condition set forth in paragraph (a)(1) of this section, that the spouse be entitled to all the income, to the extent that the income is required to be accumulated in whole or in part or may be accumulated in the discretion of any person other than the donee spouse; to the extent that the consent of any person other than the donee spouse is required as a condition precedent to distribution of the income; or to the extent that any person other than the donee spouse has the power to alter the terms of the trust so as to deprive her of her right to the income. An interest transferred in trust will not fail to satisfy the condition that the spouse be entitled to all the income merely because its terms provide that the right of the donee spouse to the income shall not be subject to assignment, alienation, pledge, attachment or claims of creditors.

(8) In the case of an interest transferred in trust, the terms “entitled for life” and “payable annually or at more frequent intervals”, as used in the conditions set forth in paragraph (a) (1) and (2) of this section, require that under the terms of the trust the income referred to must be currently (at least annually; see paragraph (e) of this section) distributable to the spouse or that she must have such command over the income that it is virtually hers. Thus, the conditions in paragraph (a) (1) and (2) of this section are satisfied in this respect if, under the terms of the trust instrument, the donee spouse has the right exercisable annually (or more frequently) to require distribution to herself of the trust income, and otherwise the trust income is to be accumulated and added to corpus. Similarly, as respects the income for the period between the last distribution date and the date of the spouse's death, it is sufficient if that income is subject to the spouse's power to appoint. Thus, if the trust instrument provides that income accrued or undistributed on the date of the spouse's death is to be disposed of as if it had been received after her death, and if the spouse has a power of appointment over the trust corpus, the power necessarily extends to the undistributed income.

(g) Power of appointment in donee spouse.

(1) The conditions set forth in paragraphs (a) (3) and (4) of this section, that is, that the donee spouse must have a power of appointment exercisable in favor of herself or her estate and exercisable alone and in all events, are not met unless the power of the donee spouse to appoint the entire interest or a specific portion of it falls within one of the following categories:

(i) A power so to appoint fully exercisable in her own favor at any time during her life (as, for example, an unlimited power to invade); or

(ii) A power so to appoint exercisable in favor of her estate. Such a power, if exercisable during life, must be fully exercisable at any time during life, or if exercisable by will, must be fully exercisable irrespective of the time of her death; or

(iii) A combination of the powers described under subdivisions (i) and (ii) of this subparagraph. For example, the donee spouse may, until she attains the age of 50 years, have a power to appoint to herself and thereafter have a power to appoint to her estate. However, the condition that the spouse's power must be exercisable in all events is not satisfied unless irrespective of when the donee spouse may die the entire interest or a specific portion of it will at the time of her death be subject to one power or the other.

(2) The power of the donee spouse must be a power to appoint the entire interest or a specific portion of it as unqualified owner (and free of the trust if a trust is involved, or free of the joint tenancy if a joint tenancy is involved) or to appoint the entire interest or a specific portion of it as a part of her estate (and free of the trust if a trust is involved), that is, in effect, to dispose of it to whomsoever she pleases. Thus, if the donor transferred property to a son and the donee spouse as joint tenants with right of survivorship and under local law the donee spouse has a power of severance exercisable without consent of the other joint tenant, and by exercising this power could acquire a one-half interest in the property as a tenant in common, her power of severance will satisfy the condition set forth in paragraph (a)(3) of this section that she have a power of appointment in favor of herself or her estate. However, if the donee spouse entered into a binding agreement with the donor to exercise the power only in favor of their issue, that condition is not met. An interest transferred in trust will not be regarded as failing to satisfy the condition merely because takers in default of the donee spouse's exercise of the power are designated by the donor. The donor may provide that, in default of exercise of the power, the trust shall continue for an additional period.

(3) A power is not considered to be a power exercisable by a donee spouse alone and in all events as required by paragraph (a)(4) of this section if the exercise of the power in the donee spouse to appoint the entire interest or a specific portion of it to herself or to her estate requires the joinder or consent of any other person. The power is not “exercisable in all events”, if it can be terminated during the life of the donee spouse by any event other than her complete exercise or release of it. Further, a power is not “exercisable in all events” if it may be exercised for a limited purpose only. For example, a power which is not exercisable in the event of the spouse's remarriage is not exercisable in all events. Likewise, if there are any restrictions, either by the terms of the instrument or under applicable local law, on the exercise of a power to consume property (whether or not held in trust) for the benefit of the spouse, the power is not exercisable in all events. Thus, if a power of invasion is exercisable only for the spouse's support, or only for her limited use, the power is not exercisable in all events. In order for a power of invasion to be exercisable in all events, the donee spouse must have the unrestricted power exercisable at any time during her life to use all or any part of the property subject to the power, and to dispose of it in any manner, including the power to dispose of it by gift (whether or not she has power to dispose of it by will).

(4) If the power is in existence at all times following the transfer of the interest, limitations of a formal nature will not disqualify the interest. Examples of formal limitations on a power exercisable during life are requirements that an exercise must be in a particular form, that it must be filed with a trustee during the spouse's life, that reasonable notice must be given, or that reasonable intervals must elapse between successive partial exercises. Examples of formal limitations on a power exercisable by will are that it must be exercised by a will executed by the donee spouse after the making of the gift or that exercise must be by specific reference to the power.

(5) If the donee spouse has the requisite power to appoint to herself or her estate, it is immaterial that she also has one or more lesser powers. Thus, if she has a testamentary power to appoint to her estate, she may also have a limited power of withdrawal or of appointment during her life. Similarly, if she has an unlimited power of withdrawal, she may have a limited testamentary power.

(h) Existence of a power in another. Paragraph (a)(5) of this section provides that a transfer described in paragraph (a) is nondeductible to the extent that the donor created a power in the trustee or in any other person to appoint a part of the interest to any person other than the donee spouse. However, only powers in other persons which are in opposition to that of the donee spouse will cause a portion of the interest to fail to satisfy the condition set forth in paragraph (a)(5) of this section. Thus, a power in a trustee to distribute corpus to or for the benefit of the donee spouse will not disqualify the trust. Similarly, a power to distribute corpus to the spouse for the support of minor children will not disqualify the trust if she is legally obligated to support such children. The application of this paragraph may be illustrated by the following examples:
