California’s proposed billionaire tax was trailing in early election returns, according to CalMatters’ election-night report. That is a snapshot of an unfinished count, not a certified result. The measure attracting attention is Proposition 40, and its fate also intersects with two competing propositions.

Reporting checked on November 4, 2026 (Korea Standard Time). CalMatters reported roughly 57% voting against Prop. 40 with about 35% of votes counted, citing the Associated Press. Those figures describe the report’s early returns and may have changed since.

What Proposition 40 would change

The California Secretary of State’s official voter guide, featuring analysis by the Legislative Analyst, describes a one-time levy of 5% of net worth on billionaires who were California residents on January 1, 2026. Payment would be due in 2027, with a more expensive installment option. Real estate, pensions and retirement accounts would generally be excluded.

The guide says 90% of the proceeds would go to public health-care services. The remaining share would support education, food assistance and administration. It estimates temporary revenue in the tens of billions of dollars, while warning that behavioral responses could reduce ongoing income-tax revenue.

Why Props. 41 and 42 also matter

The official analysis cautions that Prop. 40 could be prevented from becoming law even with majority support if Prop. 41 or 42 received more yes votes and courts found the measures conflicted. Watching the Prop. 40 percentage alone therefore would not answer every question about implementation.

How to read the next update

Keep three questions separate: what the proposal says, what the count currently shows, and whether a final result has been certified. This article explains the proposal and attributes the early count to its reporting source; it does not declare passage or defeat.
