(a) In general—(1) Surviving spouse only noncharitable beneficiary. With respect to estates of decedents dying after December 31, 1981, subject to section 2056(d), if the surviving spouse of the decedent is the only noncharitable beneficiary of a charitable remainder annuity trust or a charitable remainder unitrust described in section 664 (qualified charitable remainder trust), section 2056(b)(1) does not apply to the interest in the trust that is transferred to the surviving spouse. Thus, the value of the annuity or unitrust interest passing to the spouse qualifies for a marital deduction under section 2056(b)(8) and the value of the remainder interest qualifies for a charitable deduction under section 2055. If an interest in property qualifies for a marital deduction under section 2056(b)(8), no election may be made with respect to the property under section 2056(b)(7). For purposes of this section, the term non-charitable beneficiary means any beneficiary of the qualified charitable remainder trust other than an organization described in section 170(c).

(2) Interest for life or term of years. The surviving spouse's interest need not be an interest for life to qualify for a marital deduction under section 2056(b)(8). However, for purposes of section 664, an annuity or unitrust interest payable to the spouse for a term of years cannot be payable for a term that exceeds 20 years.

(3) Payment of state death taxes. A deduction is allowed under section 2056(b)(8) even if the transfer to the surviving spouse is conditioned on the spouse's payment of state death taxes, if any, attributable to the qualified charitable remainder trust. See § 20.2056(b)-4(c) for the effect of such a condition on the amount of the deduction allowable.

(b) Charitable remainder trusts where the surviving spouse is not the only noncharitable beneficiary. In the case of a charitable remainder trust where the decedent's spouse is not the only noncharitable beneficiary (for example, where the noncharitable interest is payable to the decedent's spouse for life and then to another individual for life), the qualification of the interest as qualified terminable interest property is determined solely under section 2056(b)(7) and not under section 2056(b)(8). Accordingly, if the decedent died on or before October 24, 1992, or the trust otherwise comes within the purview of the transitional rules contained in § 20.2056(b)-7(e)(5), the spousal annuity or unitrust interest may qualify under § 20.2056(b)-(7)(e) as a qualifying income interest for life.
