AI-generated · Source-checked by AI · Nov 5, 2026
Based on the full Introduced in House · 2025-03-04 text. This explanation has not received human editorial review. This overview describes the proposal’s major provisions; it does not establish what its real-world effects would be.
What it would do
This proposal would rename the standard federal income tax deduction the “guaranteed deduction” and temporarily increase it for tax years beginning in 2026 and 2027. The extra deduction would vary by filing status and shrink for taxpayers above specified income thresholds. These amounts would increase the deduction used in calculating taxable income; they are not promised dollar-for-dollar tax savings.

by striking standard deduction each place it appears and inserting guaranteed deduction
In the case of a taxable year beginning after December 31, 2025, and before January 1, 2028, the guaranteed deduction shall be increased by the amount of the bonus guaranteed deduction.
(i) $4,000 in the case of a joint return or a surviving spouse (as defined in section 2(a)), (ii) $3,000 in the case of a head of household, and (iii) $2,000 in any other case.
The bonus guaranteed deduction determined under subparagraph (B) shall be reduced (but not below zero) by 5 percent of so much of the taxpayer's modified adjusted gross income as exceeds the threshold amount.
Section 2 would replace “standard deduction” with “guaranteed deduction” in Internal Revenue Code section 63 and make corresponding terminology changes elsewhere in the Code. The renaming would apply to tax years beginning after December 31, 2025.

Section 63 of the Internal Revenue Code of 1986 is amended— (1) by striking standard deduction each place it appears and inserting guaranteed deduction
Section 3 would add a bonus deduction for tax years beginning in 2026 or 2027: $4,000 for joint returns or qualifying surviving spouses, $3,000 for heads of household, and $2,000 in other cases, before inflation adjustments and income-based reductions. The bonus would not apply to tax years beginning in 2028 or later.

In the case of a taxable year beginning after December 31, 2025, and before January 1, 2028, the guaranteed deduction shall be increased by the amount of the bonus guaranteed deduction.
the bonus guaranteed deduction is— (i) $4,000 in the case of a joint return or a surviving spouse (as defined in section 2(a)), (ii) $3,000 in the case of a head of household, and (iii) $2,000 in any other case.
For 2027, the bonus amounts would receive an inflation adjustment using the referenced tax-code formula with 2025 substituted for its 2016 base year. Any increase would be rounded down to a multiple of $50.
Check the source
In the case of a taxable year beginning after 2026, each dollar amount in subparagraph (B) 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 2025 for 2016 in subparagraph (A)(ii) thereof. If any increase under this subparagraph is not a multiple of $50, such increase shall be rounded to the next lowest multiple of $50.
The bonus would decrease by 5 percent of income above $400,000 for joint filers or qualifying surviving spouses, $300,000 for heads of household, and $200,000 for other filers. This means a $50 reduction for each $1,000 above the applicable threshold. The bonus could fall to zero but could not become negative.

The bonus guaranteed deduction determined under subparagraph (B) shall be reduced (but not below zero) by 5 percent of so much of the taxpayer's modified adjusted gross income as exceeds the threshold amount.
the threshold amount is— (I) $400,000 in the case of a joint return or a surviving spouse (as defined in section 2(a)), (II) $300,000 in the case of a head of household, and (III) $200,000 in any other case.
For the income-based reduction, the bill would use “modified adjusted gross income”: adjusted gross income plus amounts excluded from gross income under tax-code sections 911, 931, or 933.
Check the source
the term modified adjusted gross income means adjusted gross income increased by any amount excluded from gross income under section 911, 931, or 933.

What this analysis cannot establish
The supplied full text is the introduced House version dated March 4, 2025. Its provisions are proposals, not evidence of enacted law. The May 8, 2025 actions snapshot does not establish subsequent advancement, amendment, or enactment.
The bundle does not reproduce the existing tax-code provisions being amended or referenced. It therefore does not establish the underlying deduction amounts, complete eligibility rules, surviving-spouse definition, or details of the income exclusions.
The exact inflation-adjusted 2027 bonus amounts and individual taxpayers’ tax savings cannot be determined from the supplied evidence.
No member earmark disclosures, committee reports, or conference materials are supplied; the category reviews are limited to the introduced bill text.
