Shelter Act

Subpart A of part IV of subchapter A of chapter 1 of the Internal Revenue Code of 1986, as amended by section 70411 of Public Law 119–21, is amended by inserting after section 25F the following new section:

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 25 percent of the qualified disaster mitigation expenditures made by the taxpayer during such taxable year.

Subject to subsection (b), the credit allowed to a taxpayer under paragraph (1) for any taxable year shall not exceed $3,750 (or, in the case of a joint return, $7,500).

Subject to subsection (b), the credit allowed under paragraph (1) with respect to a qualified dwelling unit of the taxpayer for any taxable year shall not exceed the excess (if any) of $15,000 over the aggregate credits allowed under such paragraph with respect to such qualified dwelling unit for all prior taxable years ending after December 31, 2025.

The amount of the credit allowed under subsection (a)(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 subsection as—

(A) the amount (not less than zero) equal to the adjusted gross income of the taxpayer for such taxable year minus $100,000, bears to

(B) $50,000.

In the case of any taxable year after 2026, each of the dollar amounts under paragraph (1) shall be increased by an amount equal to—

(A) such dollar amount, multiplied by

(B) 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 2025 for calendar year 2016 in subparagraph (A)(ii) thereof.

If any reduction determined under paragraph (1) is not a multiple of $50, or any increase under paragraph (2) is not a multiple of $50, such amount shall be rounded to the nearest multiple of $50.

If a joint return is filed by the taxpayer for the taxable year, for purposes of determining the amount of any reduction under paragraph (1) for such taxable year, the dollar amounts under such paragraph (after application of paragraphs (2) and (3)) shall be doubled.

For purposes of this section—

The Secretary, in consultation with the Administrator of the Federal Emergency Management Agency, may publish a list of inapplicable expenditures which are region-specific in order to prohibit the application of subsection (a) for expenditures relating to hazards which are not relevant to the location of the qualified dwelling unit.

The term qualified disaster mitigation expenditure shall not include any expenditure or portion thereof which is paid, funded, or reimbursed by a Federal, State, or local government entity, or any political subdivision, agency, or instrumentality thereof.

The term qualified dwelling unit means a dwelling unit which is located—

(A) in the United States or in a territory of the United States, and

In the case of an expenditure described in clause (i) or (ii) of subsection (c)(1)(A), such expenditure shall be taken into account in determining the qualified disaster mitigation expenditures made by the taxpayer during the taxable year only if the onsite preparation, assembly, or original installation of the property with respect to which such expenditure is made has been completed in a manner that is deemed to be in compliance with the latest published editions of relevant consensus-based codes, specifications, and standards or any more restrictive Federal, State, or local floodplain management standards and consistent with floodplain management regulations for the local jurisdiction in which the qualified dwelling unit is located.

The term latest published editions means, with respect to relevant consensus-based codes, specifications, and standards, either of the 2 most recently published editions.

For purposes of this section, expenditures for labor costs properly allocable to the onsite preparation, assembly, or original installation of the property described in clause (i) or (ii) of subsection (c)(1)(A) shall be taken into account in determining the qualified disaster mitigation expenditures made by the taxpayer during the taxable year.

For purposes of this section, expenditures for the cost of any inspection required under subsection (d) which is properly allocable to the inspection of the preparation, assembly, or installation of the property described in clause (i) or (ii) of subsection (c)(1)(A) shall be taken into account in determining the qualified disaster mitigation expenditures made by the taxpayer during the taxable year.

If the credit allowable under subsection (a)(1) for any taxable year exceeds the applicable tax limit for such taxable year, such excess shall be a carryover to each of the 5 succeeding taxable years and, subject to the limitations of paragraph (2), shall be added to the credit allowable by subsection (a)(1) for such succeeding taxable year.

The amount of the unused credit which may be taken into account under paragraph (1) for any taxable year shall not exceed the amount (if any) by which the applicable tax limit for such taxable year exceeds the sum of—

(A) the credit allowable under subsection (a)(1) for such taxable year determined without regard to this subsection, and

(B) the amounts which, by reason of this subsection, are carried to such taxable year and are attributable to taxable years before the unused credit year.

For purposes of this subsection, the term applicable tax limit means the limitation imposed by section 26(a) for the taxable year reduced by the sum of the credits allowable under this subpart (other than this section).

Any taxpayer claiming the credit under this section shall provide the Secretary with adequate documentation regarding the specific qualified disaster mitigation expenditures made by the taxpayer during the taxable year, as well as such other information or documentation as the Secretary may require.

Subject to paragraph (2), the amount of the credit determined under subsection (a) for any taxable year shall not exceed $5,000.

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—

(ii) $5,000,000.

In the case of any taxable year after 2026, each of the dollar amounts under subparagraph (A) shall 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 2025 for calendar year 2016 in subparagraph (A)(ii) thereof.

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.

For purposes of this section, the term qualified disaster mitigation expenditure has the same meaning given such term under paragraph (1) of section 25G(c), except that place of business shall be substituted for qualified dwelling unit each place it appears in such paragraph.

For purposes of this section, an expenditure shall not be treated as a qualified disaster mitigation expenditure (as defined in paragraph (1)) unless the taxpayer's place of business is located—

(A) in the United States or in a territory of the United States, and
