California’s Billionaire Tax Is on the 2026 Ballot: What Proposition 40 Would Do—and Whether the Rich Are Leaving

Proposition 40 would impose a one-time 5% tax on covered billionaire wealth, but reported moves and threats to leave do not prove a mass exodus or determine tax liability.

California’s proposed billionaire tax is on the ballot: Proposition 40 is listed as qualified for the November 3, 2026, general election. It would impose a one-time tax equal to 5% of the net worth of people who were California residents on January 1, 2026. Reports of wealthy people moving or threatening to leave show a fierce backlash, but they do not establish a mass exodus or determine anyone’s tax liability.

Is California’s billionaire tax on the ballot?

Yes. The California Secretary of State lists Proposition 40 as qualified for the November 3, 2026, general election, with status dated October 5, 2026. The official voter guide describes it as a one-time 5% tax on billionaire wealth. California Secretary of State initiative status; November 2026 voter guide.

What Proposition 40 would do

Under the official analysis, Proposition 40 would tax people who were California residents on January 1, 2026. The proposed levy is a one-time state tax of 5% of their net worth; it is not described as a recurring annual wealth tax. The initiative is sponsored by SEIU-UHW. Its stated rationale is to address reductions in federal funding for health care, education and food assistance. That is the proponents’ explanation for the measure, not an independent finding that the tax would fully replace those funds.

What the fiscal estimate says—and what it does not

The Legislative Analyst’s Office forecasts a temporary revenue increase in the tens of billions of dollars spread over several years. The LAO also warns that billionaires could respond in ways that reduce their income-tax payments to the state. The forecast therefore depends in part on taxpayer behavior; it is not a guaranteed net gain of that amount, nor a prediction that the state will necessarily lose revenue. LAO fiscal analysis.

How Proposition 40 interacts with Propositions 41 and 42

Proposition 40 is not the only measure whose result could matter. The LAO says that if either Proposition 41 or Proposition 42 receives more yes votes than Proposition 40, Proposition 40 could be prevented from taking effect—even if Prop. 40 itself receives a majority of yes votes. So the outcome depends on the relative yes-vote totals among these measures, not solely on whether Prop. 40 wins a simple majority.

Are billionaires leaving California because of the tax?

There is documented political opposition, including threats to leave, and reporting about some billionaires changing residences or moving business assets. The Associated Press covered the backlash and opponents’ prediction that wealthy residents could leave and take income-tax revenue with them. CalMatters’ October 2026 reporting describes reported moves and uncertainty about possible tax exposure. These reports do not establish a mass exodus caused by Proposition 40.

A reported change of residence or movement of business assets is not, by itself, a tax-authority determination of where someone is legally resident or whether the proposed tax would apply. Reporting on timing or stated intent also does not prove that a move was caused by the measure or would eliminate any liability.

What voters should keep in view

  • Ballot status: Proposition 40 is qualified for the November 3, 2026, election; it is no longer merely awaiting ballot qualification.
  • Who and what it would cover: The official analysis specifies billionaires who were California residents on January 1, 2026, and a one-time tax of 5% of net worth.
  • Revenue uncertainty: The LAO expects a temporary increase in the tens of billions of dollars over several years, while noting that behavior by affected taxpayers could reduce income-tax receipts.
  • Election interaction: A majority for Prop. 40 alone may not be enough if Prop. 41 or Prop. 42 receives more yes votes.
  • Claims about departures: Opposition and reported moves are real parts of the debate, but the cited reporting does not prove a mass departure or settle any individual’s tax status.
