What Is the One Big Beautiful Bill Act?

The One Big Beautiful Bill Act is a federal budget reconciliation bill signed into law by President Donald Trump on July 4, 2025, addressing tax policy, border security and immigration, defense, energy production, the debt limit, and adjustments to SNAP and Medicaid.

The Senate passed the bill in a 51-50 vote on July 1, with Vice President J.D. Vance casting the tie-breaking vote. It cleared the House of Representatives on July 3, 2025, in a 218-214 vote.

The bill passed through the budget reconciliation process, which meant it required only a simple Senate majority rather than 60 votes, bypassing the filibuster. That procedural choice was itself politically significant and drew sharp criticism from Democrats.

Key Tax Provisions: Who Benefits and What It Costs

Permanent TCJA Extensions

The OBBBA addressed the looming expiration of the 2017 Tax Cuts and Jobs Act tax cuts at the end of 2025 by making those tax changes permanent. It also enacted many of President Trump's campaign proposals to exempt certain types of income from tax, including tips and overtime.

Key individual tax changes include:

  • Permanent extension of lower income tax rates from the 2017 TCJA.
  • Increased standard deduction retained permanently.
  • Temporary tax exemptions on tip income, overtime pay, and senior income.
  • A private school choice tax credit and an expanded child tax credit.

Business Tax Cuts

The Act enacts large business tax cuts, most notably by providing permanent full expensing of many forms of investment.

The Fiscal Cost

The major tax provisions will reduce federal tax revenue by nearly $5.2 trillion between 2025 and 2034 on a conventional basis. Combined with nearly $1.1 trillion in net spending reductions estimated by the Congressional Budget Office, the OBBBA will increase federal budget deficits by $3.3 trillion from 2025 through 2034 on a dynamic basis.

The recently enacted law will increase borrowing by $4.1 trillion through 2034 on a conventional basis, according to CBO estimates. This includes $5.9 trillion of tax cuts and spending increases, $2.5 trillion of offsets, and over $700 billion of interest costs.

Spending Cuts and Border Policy: The Other Half of the Bill

Medicaid and SNAP Reductions

This is where the legislation has drawn the fiercest opposition. The OBBBA includes an estimated $863 billion in Medicaid cuts over the next ten years, projected to reduce enrollment by 10.3 million people by 2034.

The nonpartisan Congressional Budget Office estimated that the One Big Beautiful Bill Act will reduce federal Medicaid spending by more than $900 billion over a decade. Health policy experts noted that total spending on Medicaid is expected to still grow because of population changes and an increase in healthcare costs, but that the cuts reduce what would otherwise have been spent.

The law saves $540 billion from restricting and phasing out tax credits for clean energy and electric vehicles enacted by the Inflation Reduction Act, and nearly $300 billion from SNAP reductions.

Impacts on vulnerable populations include:

  • Work requirements tightened for Medicaid eligibility.
  • SNAP benefit access narrowed with stricter rules.
  • Reproductive health funding withheld from certain nonprofit providers.
  • More than 300 rural hospitals are currently at immediate risk of closure as the OBBBA is projected to cut Medicaid spending by over $1 trillion.

Border Security Funding

The bill provides more than $70 billion in supplemental funding over four years for U.S. Customs and Border Protection to increase border security operations, available until September 30, 2029.

Additional border measures include:

  • Physical barrier construction funding.
  • A $5,000 apprehension fee on inadmissible aliens.
  • A 1% excise tax on cash remittance transfers.
  • Funding for a biometric entry and exit system.

Around $150 billion increase in funding for the Defense Department and national security.
