California Certifies 5% Billionaire Tax for November Ballot as Tech Donors Pour in Millions

Q: How could two counter-initiatives on the ballot neutralize the billionaire tax, even if it passes?

Yes. Under California’s rule for conflicting ballot measures, the billionaire tax could still be blocked if a rival initiative also passes and wins more “yes” votes. One counter-initiative would constitutionally bar new taxes on individually owned assets, personal savings and retirement holdings, and also ban retroactive taxation. That strikes at the core of the billionaire tax, which is a one-time 5% levy on net worth above $1 billion and is written to apply retroactively to people who were California residents on Jan. 1, 2026. If both measures pass, the higher vote-getter would control, potentially voiding the tax. The second counter-initiative would require audits of programs funded by voter-approved taxes and subject new tax revenue to California’s existing spending-limit rules. Opponents argue that would prevent the billionaire-tax revenue from being handled as its backers intend and could force money to be redirected or returned under state fiscal rules, effectively canceling much of the measure’s practical effect. Even apart from direct conflict, the rival measures could trigger prolonged court fights over which provisions govern. That could delay collection and spending for years. So the billionaire tax does not need to lose outright to be neutralized; it could pass and still be overridden, constrained, or tied up if either counter-measure also passes with a larger vote total.

California’s secretary of state certified a ballot measure that would impose a one-time 5% tax on residents worth more than $1 billion, sending it to voters in November after supporters submitted more than double the required signatures.
The proposal is meant to shore up food assistance, education and healthcare programs, with backers saying it also responds to federal healthcare cuts; it would apply retroactively to billionaires who were California residents on Jan. 1, 2026.
Gavin Newsom failed to broker a last-minute deal to keep the measure off the ballot, rejecting a union offer to cut the levy to 2% despite arguing the tax would drive wealthy residents out of California.
About 200 California billionaires could be affected, and opposition is already heavily funded: Sergey Brin has spent at least $82 million and Chris Larsen at least $13.2 million against the measure.
Two rival anti-tax initiatives also qualified for November, setting up a three-measure fight that election watchers expect to trigger unprecedented spending and widespread voter confusion.

California’s $20 Billion Billionaire Tax: The 2026 Proposition 13 Battle Over Wealth, Public Services, and Economic Fallout

Overview

As of June 2026, the California Billionaire Tax Act (Proposition 13) has officially qualified for the November ballot after gathering enough signatures. The campaign is marked by a major financial gap: opponents, backed by wealthy individuals like Elon Musk and Marc Andreessen, have raised over $150 million and are running widespread ads, while supporters, mainly labor unions and progressive groups, have collected about $45 million. This funding imbalance is shaping the campaign’s messaging and reach. With public opinion closely divided and a significant portion of voters still undecided, the outcome will depend on how effectively each side communicates its case before the election.
