Involuntary conversion
(N) Involuntary conversion has the same meaning as that term is defined in 1.168(i)-6(b)(12). (iii) Computation(A) In general. If the replacement MACRS property or the replacement computer software, as applicable, meets the original use requirement in paragraph (b)(3)(ii) of this section and all other requirements of section 168(k) and this section, the remaining exchanged basis for the year of replacement and the remaining excess basis, if any, for the year of replacement for the replacement MACRS property or the replacement computer software, as applicable, are eligible for the additional first year depreciation deduction under this section. If the replacement MACRS property or the replacement computer software, as applicable, meets the used property acquisition requirements in paragraph (b)(3)(iii) of this section and all other requirements of section 168(k) and this section, only the remaining excess basis for the year of replacement for the replacement MACRS property or the replacement computer software, as applicable, is eligible for the additional first year depreciation deduction under this section. See paragraph (b)(3)(iii)(A)(3) of this section. The additional first year depreciation deduction applies to the remaining exchanged basis and any remaining excess basis, as applicable, of the replacement MACRS property or the replacement computer software, as applicable, if the time of replacement is after September 27, 2017, and before January 1, 2027; or, in the case of replacement MACRS property or replacement computer software, as applicable, described in section 168(k)(2)(B) or (C), the time of replacement is after September 27, 2017, and before January 1, 2028. The additional first year depreciation deduction is computed separately for the remaining exchanged basis and any remaining excess basis, as applicable. (B) Year of disposition and year of replacement. The additional first year depreciation deduction is allowable for the replacement MACRS property or replacement computer software in the year of replacement.

For purposes of paragraph (g)(5)(iii)(A) of this section, the remaining excess basis, if any, of the replacement MACRS property that is qualified property described in section 168(k)(2)(B) and meets the used property acquisition requirements in paragraph (b)(3)(iii) of this section is limited to the property's remaining excess basis, if any, attributable to the property's manufacture, construction, or production after September 27, 2017, and before January 1, 2027.
