California Voters to Consider Billionaire Tax Proposal in November
California voters will face a pivotal decision in November on a proposal to impose a one-time 5% tax on individuals with a net worth exceeding $1 billion, according to the Service Employees International Union Healthcare Workers West. The measure, which aims to generate $100 billion for Medicaid funding amid federal cuts, has sparked intense debate over its economic and political implications.
Union’s Stance and Revenue Goals
The proposal, backed by the Service Employees International Union Healthcare Workers West, would target individuals living in California as of Jan. 1, 2026, with net worth above $1 billion. Union President Dave Regan emphasized the measure’s necessity, stating, “I am all in on this,” while criticizing opponents as “totally out of touch.” The union argues the tax would stabilize healthcare funding, but critics warn of potential economic fallout.
Opposition from Governor and Allies

Democratic Gov. Gavin Newsom and traditional union allies oppose the measure, calling it a “temporary fix” that could drive wealthy residents out of the state. Newsom, who is considering a presidential bid, has consistently resisted tax increases during his tenure. A coalition of healthcare, education, and housing groups, including the California Medical Association, has also opposed the proposal, claiming it risks volatile revenue for critical services.
Economic and Political Concerns
The nonpartisan Legislative Analyst’s Office estimates the tax could generate tens of billions in the first few years but warns of long-term declines in income tax revenues. Silicon Valley tech leaders, including Google co-founder Sergey Brin, have funded opposition efforts, contributing $82 million to the “Building a Better California” committee. Critics argue the tax could exacerbate California’s reliance on its top 1% of earners, who provide nearly half of the state’s personal income tax revenue.
Legal and Political Challenges
Even if the measure passes, legal challenges are likely, according to Martin Gilens, a political science professor at UCLA. He noted that while the proposal aligns with growing concerns over inequality and federal cutbacks, voter support for ballot initiatives often wanes as elections approach. The union previously offered to scale back the tax to 2%, but Newsom’s office rejected the compromise.
What’s Next for the Proposal?
The outcome hinges on public sentiment, political strategies, and the influence of high-profile donors. With California’s Medicaid system facing funding shortfalls, the debate reflects broader tensions over how to address inequality and fiscal stability. The measure’s fate will be a key test for both progressive and conservative factions in the state.
