Voters rejected Proposition 40, a proposed one-time tax on assets above $1 billion, after a costly campaign; supporters say they may try again in 2028.

California voters have rejected Proposition 40, a proposed one-time tax on residents and trusts with assets above $1 billion. The Associated Press called the measure for opponents on November 9, with “no” ahead 52.8% to 47.2% as 83% of votes were counted.

The measure would have imposed a 5% tax on qualifying wealth, with proceeds primarily intended to support healthcare after federal funding cuts. Its defeat leaves California without this proposed revenue source. The available reports do not specify what programs could be affected or quantify the budget consequences.

The contest put a federalism question before voters: how a state might use its own taxing authority to respond to changes in federal support for public services. Proposition 40’s supporters framed the tax as a way to shore up healthcare. But the measure’s failure does not settle the broader dispute over federal funding, nor do the reports describe a federal legal challenge or establish that preemption was at issue.

The result also shows the reach of direct democracy in California. Voters, rather than lawmakers alone, decided whether the state should pursue this tax. Had it passed, questions of implementation and administration would have followed; the available reporting does not detail how particular assets would have been treated or what legal challenges might have arisen.

The campaign was unusually expensive. Google co-founder Sergey Brin and at least 11 other billionaires contributed a combined $269 million, while the opposition group Building a Better California spent more than $300 million, CNBC reported November 10. The figures show the scale of the spending but do not establish that campaign spending determined the outcome.

Proposition 40’s defeat does not establish a national precedent. Other states can consider different approaches under their own laws, subject to applicable constitutional and federal limits. The reports identify no state copying the measure or adopting a comparable tax in response. California’s vote instead offers a case study in how a policy proposed through a state ballot can be tested—and rejected—by voters.

Supporters said they could seek to put a similar measure on California’s 2028 ballot, according to the AP. No revised proposal or filing was described, so another campaign remains a possibility rather than a confirmed ballot question.

A separate measure, Proposition 42, backed by Brin, would bar future California wealth taxes on personal savings, assets and retirement holdings. Reports differed on its status: one said it had passed, while another said it held a narrow lead and had not been formally called. Its final result and effect on future state policy therefore remain uncertain in the provided reporting.

For now, the outcome is clear: voters rejected a specific tax proposal tied to healthcare funding. Whether the debate returns will depend on organizers and voters, while other states can draw their own conclusions about the political and fiscal limits of ballot-driven policy experiments.
