Amend CSSB 340 as follows: (1) Between SECTIONS 5 and 6 of the bill (committee printing page 4, between lines 33 and 34), insert the following section, appropriately numbered, and renumber the subsequent sections of the bill accordingly: SECTION __. Section 23.23, Tax Code, is amended by adding Subsection (f) to read as follows: (f) Notwithstanding Subsections (a) and (e) and except as provided by Subdivision (2), an improvement to property that would otherwise constitute a new improvement is not treated as a new improvement if the improvement is a replacement structure for a structure that was rendered uninhabitable or unusable by a casualty or by mold or water damage. For purposes of appraising the property in the tax year in which the structure would have constituted a new improvement: (1) the last year in which the property was appraised for taxation before the casualty or damage occurred is considered to be the last year in which the property was appraised for taxation for purposes of Subsection (a)(2)(A); and (2) the replacement structure is considered to be a new improvement only to the extent it is a significant improvement over the replaced structure as that structure existed before the casualty or damage occurred. (2) At the end of SECTION 8 of the bill (committee printing page 4, following line 64) add the following: (c) Subsection (f), Section 23.23, Tax Code, as added by this Act, applies to the appraisal of property for a tax year beginning on or after the effective date of this Act regardless of whether the casualty or mold or water damage occurred before, on, or after the effective date of this Act.
