California Billionaire Tax Moves Toward November Ballot
4/28/2026, 4:36:34 AM
One-Time 5% Tax on $1 Billion-Plus Net Worth
A citizen-initiated initiative proposes a one-time 5 % levy on California residents whose net assets equal or exceed $1 billion (the SEIU-UHW cites $1.1 billion). The measure would affect roughly 200 individuals and earmark proceeds for public health, with supporters estimating up to $100 billion in revenue.
Signature Drive and Ballot Qualification
Organizers report 1.5-1.6 million signatures, well above the 875,000 required. The California Legislative Analyst’s Office says the surplus likely covers invalid entries. Signatures must be filed by June 24 to qualify for the November ballot.
Revenue Forecast and Economic Risks
The Legislative Analyst’s Office projects “tens of billions” in upfront revenue but warns of “hundreds of millions or more a year” in ongoing costs if many high-net-worth residents relocate. Supporters argue the tax offsets federal healthcare cuts that threaten hospitals and insurance coverage.
Official Statements & Responses
Gov. Gavin Newsom warned the tax could cause wealthy residents to leave California. Mayor Matt Mahan said the measure threatens innovation. Former Health Secretary Xavier Becerra called the tax unfair to billionaires but expressed doubt about a one-time levy’s effectiveness.
Criticism & Opposition
Opponents contend that the levy may drive billionaires out of the state, reducing the tax base and harming the economy. They also argue that the tax could discourage investment and innovation, undermining California’s technology sector.
Supporters and Their Arguments
Key supporters include the Service Employees International Union United Healthcare Workers West (SEIU-UHW), activist Tom Steyer, and Rep. Katie Porter, who favors corporate taxes paired with tax relief for families. They argue the levy would offset federal healthcare cuts and protect patients.
Conflicting Reports
Sources differ on the signature total (1.5 million vs. 1.6 million) and the wealth threshold ($1 billion vs. $1.1 billion). Revenue estimates range from $100 billion to “tens of billions.” No data confirm how many billionaires might relocate.

Next Steps
