Contributions of property placed in trust

(A) Remainder interest In the case of property transferred in trust, no deduction shall be allowed under this section for the value of a contribution of a remainder interest unless the trust is a charitable remainder annuity trust or a charitable remainder unitrust (described in section 664), or a pooled income fund (described in section 642(c)(5)).

(B) Income interests, etc. No deduction shall be allowed under this section for the value of any interest in property (other than a remainder interest) transferred in trust unless the interest is in the form of a guaranteed annuity or the trust instrument specifies that the interest is a fixed percentage distributed yearly of the fair market value of the trust property (to be determined yearly) and the grantor is treated as the owner of such interest for purposes of applying section 671. If the donor ceases to be treated as the owner of such an interest for purposes of applying section 671, at the time the donor ceases to be so treated, the donor shall for purposes of this chapter be considered as having received an amount of income equal to the amount of any deduction he received under this section for the contribution reduced by the discounted value of all amounts of income earned by the trust and taxable to him before the time at which he ceases to be treated as the owner of the interest. Such amounts of income shall be discounted to the date of the contribution. The Secretary shall prescribe such regulations as may be necessary to carry out the purposes of this subparagraph.

(C) Denial of deduction in case of payments by certain trusts In any case in which a deduction is allowed under this section for the value of an interest in property described in subparagraph (B), transferred in trust, no deduction shall be allowed under this section to the grantor or any other person for the amount of any contribution made by the trust with respect to such interest.

(D) Exception This paragraph shall not apply in a case in which the value of all interests in property transferred in trust are deductible under subsection (a).
