One Big Beautiful Bill Act: what this law changes in taxes
This law amends federal tax law in 321 places, in 108 sections of the law.
Changes to tables of contents, and conforming changes
Each provision below is one sentence of the law that says a part of a federal tax law is amended or repealed. The words are the law’s own. The tax type comes from the number of the Code section the sentence names.
- Title VII, Subtitle B, Section 71305: ELIMINATING LIMITATION ON RECAPTURE OF ADVANCE PAYMENT OF PREMIUM TAX CREDIT (b)Table of contents or conforming change
Amends section 35(g)(12)(B)(ii) of the Internal Revenue Code of 1986.
“Section 35(g)(12)(B)(ii) is amended by striking ``then section 36B(f)(2)(B) shall be applied by substituting the amount determined under clause (i) for the amount determined under section 36B(f)(2)(A)'' and inserting ``then the amount determined under clause (i) shall be substituted for the amount determined under section 36B(f)(2)''.”
Effective date, in the law’s words (subsection (c)): “The amendments made by this section shall apply to taxable years beginning after December 31, 2025. Subchapter C--Enhancing Choice for Patients”
Official estimate, and an estimate of your own
Official estimate: Joint Committee on Taxation
Confirmed from the official recordThe Joint Committee on Taxation is the tax staff of Congress. It published this table for the tax provisions of this law. Amounts are in billions of dollars for one calendar year. “Proposal” is the committee’s word for those provisions.
| Income category | Change in federal taxes, billions | Change, percent | Average tax rate, present law | Average tax rate, proposal |
|---|---|---|---|---|
| Less than $15,000 | $0.5 | 9.3% | 4.0% | 4.4% |

| $1,000,000 and Above | -$114.0 | -10.1% | 31.1% | 27.8% |
| Total, All Taxpayers | -$547.4 | -10.7% | 20.9% | 18.7% |
A negative number is a tax cut for that income category as a whole. The table gives no amount for one household. The committee’s footnotes say what counts as income and as federal taxes. They are in the file.

How the estimate is worked out, and what it leaves out
- Taxable income = income before the standard deduction, minus the standard deduction (never below zero).
- Income tax = the amount the 2025 tax rate table gives for that taxable income.
- Difference = income tax under the law minus income tax without it.
The estimate leaves out:
- the added deduction for people 65 and older or blind, and the law's new deduction for seniors
- the law's new deductions for tips, overtime pay and car loan interest
- the child tax credit and every other credit
- itemized deductions, including the limit on the deduction for State and local taxes
- capital gains and qualified dividends, which have their own rates
- the alternative minimum tax, payroll taxes and State taxes
- every change that starts in tax year 2026 or later
For taxable income under $100,000 the tax table of the Internal Revenue Service works in $50 steps, so the tax on a return can differ from this estimate by a few dollars.
Where this comes from
The provisions are read from our own saved copy of the law. The code beside it is its fingerprint, a short code that changes if the file’s contents change.

How we read a law for this section
- A provision is one sentence of the law that says a part of a tax law "is amended" or "is repealed". The words are quoted from our saved copy of the law. Words inside text the law inserts into another law are not read as provisions.
- A sentence counts when it names the Internal Revenue Code of 1986 or title 26 of the United States Code; when it says "such Code" and the last Code named in that section of the law is the Internal Revenue Code of 1986; when the law says that its amendments are to be read as amendments to the Internal Revenue Code of 1986 and the sentence names no other law; or when the sentence names no law at all and the amending sentence before it, in the same section of the law, amended the Internal Revenue Code of 1986.
- A sentence that amends the Harmonized Tariff Schedule of the United States or the Tariff Act of 1930 is listed under "Tariffs and customs duties".
- The tax type comes from the number of the Code section the sentence names. Sections 1 to 5, 21 to 26, 32, 35, 36, 36B, 62, 63, 67, 68, 151 to 153 and 211 to 224 apply to individuals: "Individual income tax". Sections 11, 12, 59A, 241 to 250, 301 to 385, 531 to 565 and 1501 to 1564 apply to corporations: "Corporate income tax". Every other section from 1 to 1400Z and 1411 to 1564 is "Income tax, individuals and businesses". Sections 1401 to 1403 and 3101 to 3512: "Payroll taxes". Sections 2001 to 2801: "Estate and gift taxes". Sections 4001 to 5891: "Excise taxes". Every other section, such as the rules on returns, penalties and trust funds: "Other tax law".
- A sentence that names a chapter or subtitle of the Code and no section is sorted by that chapter or subtitle. A sentence that adds a new section is sorted by the new section's number.
- "Old and new" is shown only where the law says both: "striking X and inserting Y". Other dollar amounts and percentages in the sentence are listed as printed.
- A change to a table of contents or a change headed "Conforming" or "Clerical" is listed apart.
- A law reads "This law changes no tax" only when our saved copy reaches the end of the law, no sentence above is found, the text does not name the Internal Revenue Code of 1986, the Internal Revenue Service, the Harmonized Tariff Schedule of the United States, a tariff, a duty or a named tax, and the margin of the official print cites title 26 of the United States Code nowhere.
- Nothing here says how much tax anyone pays. That takes figures the law's text does not state.
