"Big Beautiful Bill": $4.5T tax cuts, +$3.4T deficit

Summary

On July 4, 2025, President Trump signed the budget-reconciliation law widely called the "One Big Beautiful Bill Act" (H.R. 1, Public Law 119-21). It makes the expiring 2017 tax cuts permanent and adds new temporary deductions - about $4.5 trillion in tax cuts over a decade - partly offset by roughly $1.4 trillion in cuts to Medicaid, SNAP, and student aid. CBO scored it as increasing the federal deficit by about $3.4 trillion through 2034 ($4.1 trillion including interest).

What happened

H.R. 1 passed the House 215-214 on May 22, 2025 and the Senate 51-50 on July 1 with Vice President Vance breaking the tie, after the parliamentarian's "Byrd bath" stripped dozens of provisions - including the bill's own "One Big Beautiful Bill Act" short title, so the enacted law (P.L. 119-21) technically has no short title. Senate Republicans used a "current-policy baseline" to score the ~$3.8 trillion tax-cut extension as costing $0; under CBO's conventional scoring the law increases deficits by ~$3.4 trillion. The law also raised the statutory debt ceiling by $5 trillion. The tax provisions took effect for tax year 2025; the offsetting Medicaid and SNAP cuts phase in through 2026-2028.

Impact on the United States

The Penn Wharton Budget Model found the top 10% of the income distribution receives about 80 percent of the law's total value, while, once the Medicaid and SNAP cuts are counted, the lowest-income households are net worse off - losing about 1.1% of income in 2027, deepening to roughly 7.4% by 2033. The ~$3.4 trillion in added deficits ($4.1 trillion with interest) raise debt-service costs borne by all taxpayers.

Documented effects

1. Jul 2025CBO estimated the law increases the deficit by ~$3.4 trillion over 2025-2034 (conventional), composed of ~$4.5 trillion in lost revenue offset by ~$1.1 trillion in net spending cuts; ~$4.1 trillion including interest.[1]
2. Permanently extending the 2017 law's lower individual income tax rates is the largest single piece (~$2.2 trillion); new temporary deductions - no tax on tips and overtime and a $6,000 senior deduction - expire after 2028, while the SALT cap rises to $40,000 through 2029 before reverting to $10,000 in 2030.[2][5]
3. The Penn Wharton Budget Model projected the lowest-income quintile is net worse off after the Medicaid and SNAP cuts - about -1.1% of income in 2027, worsening to -7.4% by 2033 - while the top 10% of the income distribution receives about 80 percent of the total value.[3]
4. Jul 4, 2025The law raised the statutory debt limit by $5 trillion.[5]

Why this is rated critical

The largest single fiscal action of the administration: ~$4.5T in tax cuts, with the top 10% receiving about 80% of the value (Penn Wharton Budget Model), partly offset by ~$1.4T in Medicaid/SNAP/student-aid cuts; CBO scores it as adding ~$3.4T to the deficit ($4.1T with interest). It raised the debt ceiling $5T, and PWBM projects the lowest-income households end up net worse off.

1. Sep 29, 2026CorrectedKey facts

   The effect described the ~$2.2 trillion item as the whole permanent extension of the 2017 individual tax cuts; in the Bipartisan Policy Center's JCT-based table it is the lower individual income tax rates alone (seven major 2017-law extensions total ~$3.7 trillion net). It also said the $40,000 SALT cap sunsets after 2028; under section 70120 of the law the higher cap applies through 2029 and reverts to $10,000 for 2030 onward. The tips, overtime and $6,000 senior deductions do expire after 2028. The debt-limit effect was cited to CRFB, which does not mention it; the law's text raises the limit by $5,000,000,000,000 (the "$36.1T to $41.1T" levels are not in either source and are removed).[2][5]

2. Sep 29, 2026ClarifiedSource

   Added the official roll calls for the vote counts (House 215-214 on May 22, 2025; Senate 50-50 with the Vice President voting yea on July 1, 2025). Reworded "masking", which characterized intent, to a neutral description. Relabeled the Bipartisan Policy Center, Penn Wharton Budget Model and CRFB as Tier 3 (nonpartisan analysis, not news outlets) and corrected their publication dates.[1][2][6][7]

3. Sep 29, 2026CorrectedUS impact

   Two claims had no cited source: that the Tax Policy Center found the top 1% gain about 3.5% of after-tax income (no TPC source is cited; the Penn Wharton Budget Model table shows a 3.5% gain for the 95th-99th percentiles in 2027, not the top 1%), and that "about 16 million more Americans are projected to be uninsured by 2034" (not in any cited source). Both are removed. The effect saying "top earners capture roughly 80%" is made precise: PWBM says the top 10% of the income distribution receives about 80 percent of the total value. "Sharply regressive" is replaced with the sourced distribution figures.[1][3]

4. Sep 29, 2026ClarifiedSeverity rationale

   The severity rationale called the tax cuts 'mostly regressive' without attribution; it now states the Penn Wharton Budget Model's distributional finding. Severity unchanged.

   Previously

   The largest single fiscal action of the administration: ~$4.5T in mostly regressive tax cuts, partly paid for by ~$1.4T in Medicaid/SNAP/student-loan cuts, adding ~$3.4T to the deficit ($4.1T with interest) and raising the debt ceiling $5T - while leaving the lowest-income Americans net worse off.

   Now

   The largest single fiscal action of the administration: ~$4.5T in tax cuts, with the top 10% receiving about 80% of the value (Penn Wharton Budget Model), partly offset by ~$1.4T in Medicaid/SNAP/student-aid cuts; CBO scores it as adding ~$3.4T to the deficit ($4.1T with interest). It raised the debt ceiling $5T, and PWBM projects the lowest-income households end up net worse off.

5. Sep 29, 2026CorrectedCost estimate

   The booked-so-far figure (~$300B) had no source; it now uses CBO's official estimate of the law's revenue loss for FY2025 plus three quarters of FY2026, through mid-2026 ($130.9B + 0.75 x $460.5B). The 10-year figure now uses CBO's exact total ($4,485.8B). The 2040 projection was unsourced and implied the permanent tax cuts would cost only ~$170B a year after 2034; it now extends CBO's FY2033-34 revenue loss (~$463B a year) through 2040.

   Previously

   $300B booked; $4.5T by 2035; $5.5T by 2040

   Now

   $476.3B booked; $4.49T by 2035; $7.27T by 2040
