California rejects billionaire tax; FPPC records a five-to-one funding gap

California voters rejected Proposition 40, the one-time wealth tax aimed at billionaires. The Associated Press called the race at 6:28 p.m. Pacific on November 9, with 52.7 percent voting No and 47.2 percent Yes. Ballot counting continues, and California is scheduled to certify the result December 11.

The measure would have charged California residents who were billionaires on January 1, 2026 a one-time tax equal to 5 percent of net worth above $1 billion, generally excluding real estate, pensions and retirement accounts. The payment would have been due in 2027. Ninety percent of the revenue was designated for health care, with the rest divided among education, food assistance and administration.

The Legislative Analyst estimated that the tax could have produced tens of billions of dollars temporarily, while stressing that the amount was difficult to predict. The same analysis said departures or other changes by affected taxpayers could reduce ongoing state income-tax revenue by less than $1 billion a year. The vote leaves both the projected one-time revenue and that projected ongoing risk unrealized.

The Fair Political Practices Commission lists $169.8 million in aggregated top contributions opposing Proposition 40 and $32.4 million supporting it—a 5.24-to-1 edge.

Those numbers are not total campaign spending. The FPPC list covers reported top contributors, can omit smaller contributors and committees, and warns that money to committees working on multiple measures can be counted on more than one proposition. Broader figures reported by Reuters and CalMatters include campaigns against related ballot measures and should not be treated as Proposition 40-only totals.

The official record measures campaign resources, not voter motivation. It shows a large financing advantage for the No side; it does not establish why millions of Californians voted against the measure.

The contrary case was substantial. Gov. Gavin Newsom opposed the measure, as did the California Teachers Association, Planned Parenthood affiliates and several health organizations. Opponents argued that the levy could drive wealthy taxpayers and investment from California, while the official fiscal analysis identified a real, though bounded, risk to future income-tax revenue.

Supporters, including health-care unions and other labor groups, argued that extreme wealth could absorb the levy and that the money was needed after federal cuts. The campaign divided Democratic officials and aligned organizations rather than producing a simple partisan contest.

The result means the proposed levy will not be collected and its projected temporary funding will not reach the designated public programs. The campaign-finance record shows a large messaging and organizing advantage for the No side, but does not establish that the advantage determined the voters’ decision.

Supporters have discussed returning with a revised measure. For this election, the documented findings are a rejected tax, an opposition top-contributor edge greater than five to one and an uncertified vote whose causes cannot be reduced to campaign money.
