This subparagraph shall be applied separately with respect to property to which subclause (I) does not apply by reason of the preceding sentence prior to its application to property to which subclause (I) does apply.
For purposes of clause (iv), the term “qualified farmer or rancher” means a taxpayer whose gross income from the trade or business of farming (within the meaning of section 2032A(e)(5)) is greater than 50 percent of the taxpayer’s gross income for the taxable year.
If the aggregate amount of contributions described in clause (i) exceeds the applicable limitation under clause (i) for any taxable year described in such clause, such excess shall be treated (in a manner consistent with the rules of subsection (d)(1)) as a charitable contribution to which clause (i) applies in each of the 5 succeeding years in order of time.
Contributions taken into account under this subparagraph shall not be taken into account under subparagraph (A).
For each taxable year described in clause (i), and each taxable year to which any contribution under this subparagraph is carried over under clause (ii), subparagraph (A) shall be applied by reducing (but not below zero) the contribution limitation allowed for the taxable year under such subparagraph by the aggregate contributions allowed under this subparagraph for such taxable year.
For purposes of this section, the term “contribution base” means adjusted gross income (computed without regard to any net operating loss carryback to the taxable year under section 172).
If the aggregate amount of contributions described in clause (i) exceeds the limitation of clause (i), such excess shall be treated (in a manner consistent with the rules of subsection (d)(2) other than subparagraph (C) thereof) as a charitable contribution to which clause (i) applies in each of the 15 succeeding taxable years in order of time.
If the aggregate amount of contributions described in clause (i) exceeds the limitation of clause (i), such excess shall be treated (in a manner consistent with the rules of subsection (d)(2) other than subparagraph (C) thereof) as a charitable contribution to which clause (i) applies in each of the 15 succeeding taxable years in order of time.

In applying subparagraph (A), the excess determined under subparagraph (A) for the contribution year shall be reduced to the extent that such excess reduces taxable income (as computed for purposes of the second sentence of section 172(b)(2)) and increases the net operating loss deduction for a taxable year succeeding the contribution year.
In the case of any taxable year from which an excess is carried forward (determined without regard to this subparagraph) under any carryover rule, the applicable carryover rule shall be applied by increasing the excess determined under such applicable carryover rule for the contribution year (before the application of subparagraph (B)) by the amount attributable to the charitable contributions to which such rule applies which is not allowed as a deduction for the contribution year by reason of subsection (b)(1)(I).
Any charitable contribution taken into account under subsection (b)(2)(A) for any taxable year which is not allowed as a deduction by reason of clause (ii) thereof shall be taken into account as a charitable contribution for the succeeding taxable year, except that, for purposes of determining under this subparagraph whether such contribution is allowed in such succeeding taxable year, contributions in such succeeding taxable year (determined without regard to this paragraph) shall be taken into account under subsection (b)(2)(A) before any contribution taken into account by reason of this paragraph.
No charitable contribution may be carried forward under subparagraph (A) to any taxable year following the fifth taxable year after the taxable year in which the charitable contribution was first taken into account. For purposes of the preceding sentence, contributions shall be treated as allowed on a first-in first-out basis.
In the case of any taxable year from which a charitable contribution is carried forward under subparagraph (A) (determined without regard this subparagraph), subparagraph (A) shall be applied by substituting “clause (i) or (ii)” for “clause (ii)”.
The amount of charitable contributions carried forward under subparagraph (A) shall be reduced to the extent that such carryfoward would (but for this subparagraph) reduce taxable income (as computed for purposes of the second sentence of section 172(b)(2)) and increase a net operating loss carryover under section 172 to a succeeding taxable year.

For purposes of subsection (b)(2)(B), such contributions shall be treated as allowable under subsection (b)(2)(A).
For purposes of this subparagraph, the term “apparently wholesome food” has the meaning given to such term by section 22(b)(2) of the Bill Emerson Good Samaritan Food Donation Act (42 U.S.C. 1791(b)(2)), as in effect on the date of the enactment of this subparagraph.

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.

In the case of a contribution (not made by a transfer in trust) of an interest in property which consists of less than the taxpayer’s entire interest in such property, a deduction shall be allowed under this section only to the extent that the value of the interest contributed would be allowable as a deduction under this section if such interest had been transferred in trust. For purposes of this subparagraph, a contribution by a taxpayer of the right to use property shall be treated as a contribution of less than the taxpayer’s entire interest in such property.
For purposes of this section, in determining the value of a remainder interest in real property, depreciation (computed on the straight line method) and depletion of such property shall be taken into account, and such value shall be discounted at a rate of 6 percent per annum, except that the Secretary may prescribe a different rate.
No deduction shall be allowed under this section for an out-of-pocket expenditure made by any person on behalf of an organization described in subsection (c) (other than an organization described in section 501(h)(5) (relating to churches, etc.)) if the expenditure is made for the purpose of influencing legislation (within the meaning of section 501(c)(3)).

There is hereby imposed on any organization described in subsection (c) an excise tax equal to the premiums paid by such organization on any life insurance, annuity, or endowment contract if the payment of premiums on such contract is in connection with a transfer for which a deduction is not allowable under subparagraph (A), determined without regard to when such transfer is made.
For purposes of clause (i), payments made by any other person pursuant to an understanding or expectation referred to in subparagraph (A) shall be treated as made by the organization.
