Refundable personal credit for disaster mitigation expenditures (a) In general Subpart C of part IV of subchapter A of chapter 1 of the Internal Revenue Code of 1986 (relating to refundable credits) is amended by inserting after section 36B the following new section: 36C. Disaster mitigation expenditures (a) Allowance of credit In the case of an individual, there shall be allowed as a credit against the tax imposed by this chapter for the taxable year an amount equal to 50 percent of the qualified disaster mitigation expenditures made by the taxpayer during such taxable year. (b) Maximum credit (1) In general Subject to paragraphs (2) and (3), the credit allowed under subsection (a) to any taxpayer for any taxable year shall not exceed the excess of— (A) $25,000 (or, in the case of a married individual filing a separate return, 50 percent of such amount), over (B) the amount of credit allowed to the taxpayer under this section for all preceding taxable years. (2) Phaseout The amount under paragraph (1) for the taxable year shall be reduced (but not below zero) by an amount which bears the same ratio to the amount under such paragraph as— (A) the excess (if any) of— (i) the taxpayer’s adjusted gross income for such taxable year, over (ii) $200,000, bears to (B) $100,000. (3) Limitation in the case of joint occupancy In the case of any dwelling unit with respect to which qualified disaster mitigation expenditures are made and which is jointly occupied and used during any calendar year as a residence by two or more individuals, the following rules shall apply: (A) Maximum expenditures The maximum amount of such expenditures which may be taken into account under subsection (a) by all such individuals with respect to such dwelling unit during such calendar year shall be $25,000. (B) Allocation of expenditures The expenditures allocated to any individual for the taxable year in which such calendar year ends shall be an amount equal to the lesser of— (i) the amount of expenditures made by such individual with respect to such dwelling during such calendar year, or (ii) the maximum amount of such expenditures set forth in subparagraph (A) multiplied by a fraction— (I) the numerator of which is the amount of such expenditures with respect to such dwelling made by such individual during such calendar year, and (II) the denominator of which is the total expenditures made by all such individuals with respect to such dwelling during such calendar year. (4) Inflation adjustment (A) In general In the case of any taxable year after 2025, the $25,000 dollar amounts under paragraphs (1)(A) and (3), the $200,000 amount under paragraph (2)(A)(ii), and the $100,000 amount under paragraph (2) (B) shall each be increased by an amount equal to— (i) such dollar amount, multiplied by (ii) the cost-of-living adjustment determined under section 1(f)(3) for the calendar year in which the taxable year begins, determined by substituting calendar year 2024 for calendar year 2016 in subparagraph (A)(ii) thereof. (B) Rounding If any reduction determined under subparagraph (A) is not a multiple of $50, or any increase under subparagraph (B) is not a multiple of $50, such amount shall be rounded to the nearest multiple of $50.
