California voters have rejected Proposition 40, a ballot measure that would have imposed a one-time 5% tax on the state's billionaires. The Associated Press declared the measure defeated on Monday evening, with 52.8% of voters opposing the tax and 47.2% supporting it, based on 83% of the vote counted.
The proposal, known as the California Billionaire Tax Act, aimed to raise approximately $100 billion over five years to fund healthcare programs, education, and food assistance. Proponents argued that the tax was necessary to address federal funding cuts to healthcare in California.
Opponents, including California billionaires like Google co-founder Sergey Brin, raised more than $379 million to defeat the measure, outspending supporters by more than 250-1, according to The Washington Post. Brin alone contributed at least $132 million to fight the tax.
The tax would have been levied against the 214 billionaires living in California as of January 1, 2026, according to Forbes data compiled by Americans for Tax Fairness. Critics argued that the tax would drive wealthy individuals out of the state, potentially harming California's long-term tax base.
Supporters of the measure, including economists, noted that between 2019 and 2025, California income tax paid by billionaires was only 1.6% of their $1.4 trillion wealth gain, much less than what ordinary Californians pay on their paychecks. Proponents also highlighted that billionaires can accumulate substantial wealth from the stock market and business valuations without paying income tax on those gains until they are realized.
The billionaire tax proposal was part of a broader set of ballot measures across the United States. While voters in Virginia and Missouri overwhelmingly passed ballot measures protecting abortion rights, Florida voters approved a significant property tax cut.
What this adds
The opposition campaign against Proposition 40 was the most expensive in state history, with all told, the billionaires mounting a nearly $425 million battle against the measure, according to The Guardian.
