Home Mortgage Interest Credit Act of 2026

This Act may be cited as the Home Mortgage Interest Credit Act of 2026.
Subpart A of part IV of subchapter A of chapter 1 of the Internal Revenue Code of 1986 is amended by inserting after section 25F the following new section:
There shall be allowed as a credit against the tax imposed by this chapter for the taxable year an amount equal to the aggregate amount of qualified residence interest paid or accrued by the taxpayer during such taxable year.
For purposes of this section—
The term qualified residence interest means any interest on acquisition indebtedness with respect to the qualified residence of the taxpayer. For purposes of the preceding sentence, the determination of whether any property is the qualified residence of the taxpayer shall be made as of the time the interest is accrued.
The term acquisition indebtedness means any indebtedness which—
is incurred in acquiring, constructing, or substantially improving any qualified residence of the taxpayer, and
is secured by such residence.
The term qualified residence means the principal residence (within the meaning of section 121) of the taxpayer.
The credit allowed under subsection (a) to any taxpayer for any taxable year shall not exceed $2,000.
In the case of a married individual filing a separate return, subparagraph (A) shall be applied by substituting $1,000 for $2,000.
If two or more individuals who are not married own and use the same residence as their qualified residence and pay or accrue qualified residence interest with respect to such residence, the amount of the credit allowed under subsection (a) shall be allocated among such individuals in such manner as the Secretary may prescribe, except that the total amount of the credits allowed to all such individuals for any taxable year shall not exceed $2,000.
The amount of the credit allowed under subsection (a) for any taxable year shall be reduced (but not below zero) by $20 for each $1,000 (or fraction thereof) by which the taxpayer’s modified adjusted gross income exceeds the threshold amount. For purposes of the preceding sentence, the term modified adjusted gross income means adjusted gross income increased by any amount excluded from gross income under section 911, 931, or 933.
For purposes of subparagraph (A), the term threshold amount means—
$300,000 in the case of a joint return or a surviving spouse (as defined in section 2(a)),
$200,000 in the case of a head of household (as defined in section 2(b)), and
$150,000 in the case of a taxpayer not described in clause (i) or (ii).
No credit or deduction shall be allowed under this chapter for any qualified residence interest taken into account in determining the credit under this section.
In the case of any taxable year beginning after 2027, each dollar amount in subsection (c) shall be increased by an amount equal to—
such dollar amount, multiplied by
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 2026 for calendar year 2016 in subparagraph (A)(ii) thereof.
No credit shall be allowed under this section to any nonresident alien.
The Secretary shall issue such regulations or other guidance as may be necessary to carry out the purposes of this section.
The table of sections for subpart A of part IV of subchapter A of chapter 1 of such Code is amended by inserting after the item relating to section 25F the following new item:
The amendments made by this section shall apply to taxable years beginning after December 31, 2026.
