Billionaire one-time wealth tax passes in California election 2026?

What’s Happening

California voters are likely to face a referendum in November 2026 on a proposal to impose a one-time 5% wealth tax on the state's roughly 200 billionaires. The levy would target a broad range of assets including stocks, bonds, privately held businesses, and intellectual property, with the stated aim of funding public education, healthcare services, and food assistance programs. This initiative represents a significant escalation in state-level efforts to tax extreme wealth, building on momentum from similar debates in cities and at the federal level. [Forbes, Mar 31]

The push for the tax is occurring amid a national political climate where left-wing activists are demanding that prospective 2028 presidential contenders embrace wealth tax proposals as a litmus test. The "Tax the Greedy Billionaires" campaign has garnered support from figures like Connecticut Senator Chris Murphy, who recently traveled to Los Angeles to endorse the concept. Concurrently, California gubernatorial candidate Tom Steyer has proposed a separate corporate AI tax to fund education, indicating that novel taxation to address public funding shortfalls is a dominant theme in the state's political discourse.

The California effort follows the recent passage of a millionaire tax in Washington state, which succeeded after a 14-year campaign highlighting the regressive nature of that state's tax system. Opponents of the California measure argue the referendum's wording could lead to tens of billions in future lost state income tax revenue and may face legal challenges. The outcome will be closely watched as a bellwether for the viability of direct voter-imposed wealth taxes on the ultra-rich in a major U.S. economy. [Guardian, Mar 31]
