California Billionaire Tax Act Faces Wealthy Opposition and Political Pushback
6/16/2026, 11:15:42 PM
Core Event
California’s proposed 2026 Billionaire Tax Act would levy a one-time 5 % tax on the net worth of residents with assets over $1 billion, targeting roughly 200 individuals with payments due in 2027, payable over five years.
Background & Context
The SEIU-UHW filed the billionaire-tax initiative in Oct 2025. By Apr 2026 it reported 1.55 million signatures, far above the 874,641 required. State officials must verify signatures by June 25. Gov. Gavin Newsom leads a campaign urging withdrawal. Key actors include SEIU-UHW chief of staff Suzanne Jimenez, Gov. Newsom, tax advisor Andrew Katzenstein, law professor David Gamage, and billionaires Larry Page, Sergey Brin, Mark Zuckerberg and Peter Thiel, who are restructuring assets to stay below $1 billion.
Data & Statistics
The tax targets ~200 residents with net worth >$1 billion. A 5 % levy could raise “tens of billions” over five years for health, education and food aid. Polls show 54 % support (PPIC) or ~50 % (UC Berkeley-Citrin). Polymarket’s odds of ballot qualification fell to 31 % in June.
Official Statements, Responses & Opposition
Gov. Newsom called the proposal “unnecessary” and warned it would “push them to relocate.” SEIU-UHW says the tax is essential for health, education and food-assistance funding, noting its signature count exceeds the threshold. Assemblywoman Laurie Davis (R-Laguna Niguel) argues the tax “shortchanges our districts $3.9 billion they need now, not in future years.” Business groups such as the California Business Roundtable have received multimillion-dollar donations from billionaires to fund opposition. Tax-planning experts caution aggressive restructuring “can get you in trouble” if it crosses legal lines.
Conflicting Reports & Gaps
Support estimates vary—54 % in a PPIC poll versus ~50 % in a UC Berkeley-Citrin poll. Polymarket’s odds fell from 90 % to 31 % in June, yet the union still claims a robust signature count. No official verification of signatures has been released, leaving ballot status uncertain.
