The terms
(B) Conservation contributions. The terms defined in 1.170A-14(j)(3) apply for purposes of this paragraph (f)(4)(iii)(B). In the case of a qualified conservation contribution that is made by a partnership or S corporation, an ultimate member's separate Form 8283 must include their own relevant basis. An upper-tier partnership's or upper-tier S corporation's separate Form 8283 must include the sum of each of its ultimate member's relevant basis (as computed in accordance with 1.170A-14(j) through (m)). This paragraph (f)(4)(iii)(B) does not apply to contributions described in section 170(h)(7)(C) and 1.170A-14(n)(2) (for contributions made outside of the three-year holding period) or section 170(h)(7)(D) and 1.170A-14(n)(3) (for contributions made by certain family partnerships or S corporations), provided that they are not also described in section 170(h)(7)(E) and 1.170A-14(n)(4) (for contributions to preserve certified historic structures), in which case this paragraph (f)(4)(iii)(B) does apply. (5) Determination of deduction amount for purposes of substantiation rules(i) In general. In determining whether the amount of a donor's deduction exceeds the amounts set forth in section 170(f)(11)(B) (noncash contributions exceeding $500), 170(f)(11)(C) (noncash contributions exceeding $5,000), or 170(f)(11)(D) (noncash contributions exceeding $500,000), the rules of paragraphs (f)(5)(ii) and (iii) of this section apply. (ii) Similar items of property must be aggregated. Under section 170(f)(11)(F), the donor must aggregate the amount claimed as a deduction for all similar items of property, as defined in 1.170A-13(c)(7)(iii), contributed during the taxable year. For rules regarding the number of qualified appraisals and Forms 8283 (Section A or Section B) required if similar items of property are contributed, see 1.170A-13(c)(3)(iv)(A) and (4)(iv)(B). (iii) For contributions of certain inventory and scientific property, excess of amount claimed over cost of goods sold taken into account(A) In general. In determining the amount of a donor's contribution of property to which section 170(e)(3) (relating to contributions of inventory and other property) or (e)(4) (relating to contributions of scientific property used for research) applies, the donor must take into account only the excess of the amount claimed as a deduction over the amount that would have been treated as the cost of goods sold if the donor had sold the contributed property to the donee.
