Vance Casts Tiebreaker Passing the One Big Beautiful Bill Act: Enabling Event for Project 2025 Treasury/Tax Chapter and Endowment-Tax Implementation

On July 1, 2025, Vice President JD Vance cast the tiebreaking vote passing the One Big Beautiful Bill Act (H.R. 1) in the U.S. Senate, 51-50 (Senate Roll Call Vote 372, 119th Congress, 1st Session, 11:56 AM). This is a VANCE-PERSONAL footprint event: the bill failed on a 50-50 deadlock until Vance’s vote made passage possible. This was Vance’s fifth tiebreaking vote of his Vice Presidency.

The Vote

Three Republicans — Rand Paul (KY), Thom Tillis (NC), and Susan Collins (ME) — joined all 45 Democrats and both independents in opposing the bill. The Senate had completed a 24-hour vote-a-rama beginning June 30, with votes on 40+ amendments; Vance also cast tiebreaking votes on two perfecting amendments during that process. The House passed the amended bill 218-214 on July 3. Trump signed it into law on July 4, 2025 (Public Law 119-21).

Why This Is Load-Bearing for Project 2025

The vance-project-2025-alignment-audit identifies this vote as the structural enabling event for Project 2025 Chapter 11 (Department of the Treasury, Stephen Moore / William Walton framework) — and for elements of Chapters 2, 5, and 6:

Chapter 11 — Treasury / Tax Policy (Moore / Walton)

• Permanent extension of the 2017 Tax Cuts and Jobs Act individual rates (~$4.5 trillion over 10 years)
• New deductions for overtime pay and tips
• IRS enforcement capacity cuts
• Tariff-alignment framework endorsed

Chapter 6 — Education (Burke framework) — Vance co-architect, not merely ratifier

• 8% tiered excise tax on university endowment net investment income for institutions with assets over $500,000 per student
• Directly derived from Vance’s December 2023 College Endowment Accountability Act (which proposed 35% on institutions over $10B; see 2023-12-14–vance-college-endowment-accountability-act-senate-bill)
• Harvard Crimson confirmed the law imposed the 8% tax on Harvard’s endowment, effective 2025. At Vance’s originally-proposed 35% rate, Harvard alone would have owed $1.79B annually.
• This is the one OBBBA provision where Vance is documented as the intellectual originator of the policy, not a ratifier of someone else’s chapter.

Chapter 5 — DHS / Immigration (Cuccinelli framework)

• $170.1 billion in new immigration enforcement appropriations
• Operationalizes the Cuccinelli-chapter infrastructure for 100,000+ ICE detention beds and mass deportation logistics

Chapter 2 — EOP / OMB (Vought framework)

• Spending restructuring aligned with Vought impoundment and “radical constitutionalist” OMB framework

Safety-net destruction (cross-chapter)

• $911 billion in Medicaid cuts over 10 years (CBO estimate)
• 11.8 million projected to lose health coverage by 2034
• New work requirements for Medicaid and SNAP recipients

Vance’s Personal Footprint Framing

This is the most consequential single legislative act in Vance’s VP tenure. Without his vote, the bill fails entirely. The OBBBA is the omnibus legislative vehicle for Project 2025’s core fiscal and institutional restructuring agenda.

Two distinct layers of Vance-personal ownership:

1. Tiebreaker vote — structurally necessary for passage. Vance’s role is analogous to his January 24, 2025 Hegseth tiebreaker but far larger in dollar and policy scope.

2. Co-architect of the endowment-tax provision — Vance’s December 2023 Senate bill is the documented predecessor of the 8% tiered tax. The alignment audit records this as the one chapter where Vance is not merely the ideological ratifier but the named policy author. His bill was blocked by Senate Democrats in December 2023; the OBBBA enacted a version (reduced from 35% to 8%) 19 months later.

See vance-project-2025-alignment-audit: “On the endowment-tax piece, Vance is the named author of the Project 2025-aligned policy, not merely a ratifier.” And: “His July 1, 2025 tiebreaking vote on the One Big Beautiful Bill Act [is] the most ideologically explicit VP policy footprint in modern US history.”

This single vote is the most consequential VP-era policy action of the entire Trump 2 term by dollar volume and breadth of Project 2025 chapter implementation.
