Tech wealth is mobilizing against it — and Governor Gavin Newsom, who opposes the state measure, is pushing a federal version of his own. California voters will face one of the most consequential — and contested — questions on the November ballot: whether to impose a one-time tax on the state's billionaires to pay for health care, education and food assistance. The measure, which [the state's Legislative Analyst's Office confirmed](https://ballotpedia.org/California_One-Time_Wealth_Tax_for_State-Funded_Healthcare,_Education,_and_Food_Assistance_Programs_Initiative_(2026)) for the November 3 ballot, would assess a single 5% levy on the net worth of Californians who were billionaires and state residents as of January 1, 2026. Payment would be spread over five years in 1% annual installments beginning in 2027. ## How the tax would work Under the initiative, the tax would apply to worldwide net worth as measured at the end of 2026, with directly held real estate, pensions and retirement accounts excluded from the calculation. Revenue would flow into a new state fund, with the bulk directed to health care programs and the remainder split between education and food assistance, [according to Ballotpedia's summary](https://ballotpedia.org/California_One-Time_Wealth_Tax_for_State-Funded_Healthcare,_Education,_and_Food_Assistance_Programs_Initiative_(2026)). Supporters estimate the tax could raise roughly $100 billion over five years, drawing on the combined fortunes of California's roughly 200 billionaires. But the figure is inherently uncertain: because the tax is tied to asset values at the end of 2026, a market downturn — or a wave of tax-avoidance maneuvers — could sharply reduce the total. Independent analysts have cautioned that the real-world yield is difficult to predict. ## A fight between labor and tech wealth The measure reached the ballot through the efforts of [SEIU-UHW](https://www.kqed.org/news/12088883/california-billionaire-tax-november-ballot-measures), the health care workers' arm of the Service Employees International Union, which declined to pull the initiative despite a late push by state leaders to negotiate it off the ballot. On the other side, some of Silicon Valley's wealthiest residents are organizing to stop it. Google co-founder Sergey Brin has bankrolled signature-gathering for rival measures designed to block or unwind a voter-approved wealth tax — including proposals to bar retroactive taxes on financial assets and to require independent audits of major tax measures. Critics describe the rival initiatives as "poison pills"; their backers cast them as guardrails against an unconstitutional and economically risky tax. Opponents warn the levy would accelerate the departure of wealthy residents to states with no such tax. Supporters counter that the measure was written to limit that escape: because liability is fixed to residency as of the start of 2026, billionaires who leave afterward would still owe. ## Newsom's two-front position No figure has navigated the debate more conspicuously than Governor Gavin Newsom, who opposes the state ballot measure even as he champions a similar idea nationally. "You may not be able to pick up and move to Texas or Florida to shelter your income from taxation," Newsom has said, "but I promise you that billionaires can, and do." Days after the measure secured its ballot spot, the governor unveiled what he called "an economic reset for America," including a [proposed federal minimum tax](https://www.pbs.org/newshour/politics/newsom-urges-a-national-billionaires-tax-while-fighting-one-in-california) on people worth more than $100 million. "The fight belongs at the federal level, where this broken system was created in the first place," Newsom said, calling for "a true minimum tax on billionaires — a modern Buffett Rule." Backers of the California measure reject that logic, arguing that waiting on Washington is not a realistic plan for funding services Californians need now. ## What comes next Both sides are expected to spend heavily before November. Labor groups will press turnout in working-class communities that stand to gain from expanded health and food programs, while opponents — anchored by tech money and business groups — will argue the state's competitiveness is at risk. Legal challenges are likely whatever the outcome, meaning that even passage would not be the end of the fight. ## Sources - [California One-Time Wealth Tax Initiative (2026)](https://ballotpedia.org/California_One-Time_Wealth_Tax_for_State-Funded_Healthcare,_Education,_and_Food_Assistance_Programs_Initiative_(2026)) - [California billionaire tax will be on November's ballot](https://www.kqed.org/news/12088883/california-billionaire-tax-november-ballot-measures) - [Newsom urges a national 'billionaires' tax' while fighting one in California](https://www.pbs.org/newshour/politics/newsom-urges-a-national-billionaires-tax-while-fighting-one-in-california)
