(a) In general. Section 2056(b)(5) provides that if an interest in property passes from the decedent to his surviving spouse (whether or not in trust) and the spouse is entitled for life to all the income from the entire interest or all the income from a specific portion of the entire interest, with a power in her to appoint the entire interest or the specific portion, the interest which passes 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 surviving 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 surviving spouse must be payable annually or at more frequent intervals.

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

(4) The power in the surviving 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 surviving spouse.

(b) Specific portion; deductible amount. If either the right to income or the power of appointment passing to the surviving spouse pertains only to a specific portion of a property interest passing from the decedent, the marital deduction is allowed only to the extent that the rights in the surviving 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 the 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. Correspondingly, 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 decedent leaves to his surviving 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 surviving 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 decedent's death, the surviving 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 surviving 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 surviving spouse, except in the case of a deduction allowable under section 2056(b)(5), relating to the exercise of a general power of appointment by the surviving spouse.

(2) Fraction or percentage share. Under section 2056(b)(10), a partial interest in property is treated as a specific portion of the entire interest if the rights of the surviving spouse in income, and the required rights as to the power described in §20.2056(b)-5(a), constitute a fractional or percentage share of the entire property interest, so that the surviving 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 the 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 estates of decedents dying on or before October 24, 1992, and certain decedents dying after October 24, 1992, with wills or revocable trusts executed on or prior to that date.

(i) In the case of estates of decedents within the purview of the effective date and transitional rules contained in paragraphs (c)(3) (ii) and (iii) of this section:

(A) 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 decedent's death, would produce income equal to such payments. However, a pecuniary amount payable annually to a surviving spouse is not treated as a right to the income from a specific portion of the trust property for purposes of this paragraph (c)(3)(i)(A) if any person other than the surviving spouse may receive, during the surviving spouse's lifetime, any distribution of the property. To determine the applicable interest rate for valuing annuities, see sections 2031 and 7520 and the regulations under those sections.

(B) 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 for purposes of paragraph (c)(2) in an amount equal to such pecuniary amount.

(ii) The rules contained in paragraphs (c)(3)(i) (A) and (B) of this section apply with respect to estates of decedents dying on or before October 24, 1992.

(iii) The rules contained in paragraphs (c)(3)(i) (A) and (B) of this section apply in the case of decedents dying after October 24, 1992, if property passes to the spouse pursuant to a will or revocable trust agreement executed on or before October 24, 1992, and either—

(A) On that date, the decedent was under a mental disability to change the disposition of the property and did not regain competence to dispose of such property before the date of death; or

(B) The decedent dies prior to October 24, 1995.

(iv) Notwithstanding paragraph (c)(3)(iii) of this section, paragraphs (c)(3)(i) (A) and (B) of this section do not apply if the will or revocable trust is amended after October 24, 1992, in any respect that increases the amount of the transfer qualifying for the marital deduction or alters the terms by which the interest so passes to the surviving spouse of the decedent.

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

(5) Examples. The following examples illustrate the application of paragraphs (a) through (c)(4) of this section:

(d) Meaning of entire interest. Because a marital deduction is allowed for each separate qualifying interest in property passing from the decedent to the decedent's surviving spouse (subject to any applicable limitations in §20.2056(a)-l(c)), for purposes of paragraphs (a) and (b) of this section, each property interest with respect to which the surviving spouse received any rights is considered separately in determining whether the surviving spouse's 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 distribution by the executor 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 paragraph (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 jursidiction 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 surviving 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 surviving 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 surviving 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 trusts 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 decedent's intention, as manifested by the terms of the trust instrument and the surrounding circumstances, that the trust should produce for the surviving 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 surviving spouse's interest shall meet the condition set forth in paragraph (a)(1) of this section if the spouse is entitled to income as 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 surviving 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 passing 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 passing 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 passing 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 passing 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 trustee will not have the effect of disqualifying an interest passing in trust unless the grant of powers evidences the intention to deprive the surviving 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 passing 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 passing 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 or other property for the personal use of the spouse will not disqualify the interest passing in trust.

(5) An interest passing in trust will not satisfy the condition set forth in paragraph (a)(1) of this section that the surviving 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 surviving 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 passing 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 is created during the decedent's life, it is immaterial whether or not the interest passing in trust satisfied the conditions set forth in paragraph (a) (1) through (5) of this section prior to the decedent's death. If a trust may be terminated during the life of the surviving spouse, under her exercise of a power of appointment or by distribution of the corpus to her, the interest passing 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 passing 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 surviving spouse; to the extent that the consent of any person other than the surviving spouse is required as a condition precedent to distribution of the income; or to the extent that any person other than the surviving spouse has the power to alter the terms of the trust so as to deprive her of her right to the income. An interest passing 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 surviving spouse to the income shall not be subject to assignment, alienation, pledge, attachment or claims of creditors.

(8) In the case of an interest passing 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 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.

(9) An interest is not to be regarded as failing to satisfy the conditions set forth in paragraph (a) (1) and (2) of this section (that the spouse be entitled to all the income and that it be payable annually or more frequently) merely because the spouse is not entitled to the income from estate assets for the period before distribution of those assets by the executor, unless the executor is, by the decedent's will, authorized or directed to delay distribution beyond the period reasonably required for administration of the decedent's estate. As to the valuation of the property interest passing to the spouse in trust where the right to income is expressly postponed, see §20.2056(b)-4.

(g) Power of appointment in surviving spouse.

(1) The conditions set forth in paragraph (a) (3) and (4) of this section, that is, that the surviving 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 surviving 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 following the decedent's death (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 (subject in either case to the provisions of §20.2053(b)-3, relating to interests conditioned on survival for a limited period); or

(iii) A combination of the powers described under subdivisions (i) and (ii) of this subparagraph. For example, the surviving 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 surviving 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 (subject to the exception in §20.2053(b)-3, relating to interests contingent on survival for a limited period).

(2) The power of the surviving 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 decedent devised property to a son and the surviving spouse as joint tenants with right of survivorship and under local law the surviving 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 conditions 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 surviving spouse entered into a binding agreement with the decedent to exercise the power only in favor of their issue, that condition is not met. An interest passing in trust will not be regarded as failing to satisfy the condition merely because takers in default of the surviving spouse's exercise of the power are designated by the decedent. The decedent 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 surviving spouse alone and in all events as required by paragraph (a)(4) of this section if the exercise of the power in the surviving 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 surviving 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 surviving 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) The power in the surviving spouse is exercisable in all events only if it exists immediately following the decedent's death. For example, if the power given to the surviving spouse is exercisable during life, but cannot be effectively exercised before distribution of the assets by the executor, the power is not exercisable in all events. Similarly, if the power is exercisable by will, but cannot be effectively exercised in the event the surviving spouse dies before distribution of the assets by the executor, the power is not exercisable in all events. However, an interest will not be disqualified by the mere fact that, in the event the power is exercised during administration of the estate, distribution of the property to the appointee will be delayed for the period of administration. If the power is in existence at all times following the decedent's death, limitations of a formal nature will not disqualify an 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 surviving spouse after the decedent's death or that exercise must be by specific reference to the power.

(5) If the surviving 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) Requirement of survival for a limited period. A power of appointment in the surviving spouse will not be treated as failing to meet the requirements of paragraph (a)(3) of this section even though the power may terminate, if the only conditions which would cause the termination are those described in paragraph (a) of §20.2056(b)-3, and if those conditions do not in fact occur. Thus, the entire interest or a specific portion of it will not be disqualified by reason of the fact that the exercise of the power in the spouse is subject to a condition of survivorship described in §20.2056(b)-3 if the terms of the condition, that is, the survivorship of the surviving spouse, or the failure to die in a common disaster, are fulfilled.

(i) [Reserved]

(j) 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 decedent created a power in the trustee or in any other person to appoint a part of the interest to any person other than the surviving spouse. However, only powers in other persons which are in opposition to that of the surviving 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 a surviving 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:
