California’s Billionaire Tax Faces Polling Slump and Funding Uncertainty

Key points

• Proposition 40 polls in the mid-40s, a warning sign for a measure needing broad coalition support.
• Independents have shifted to opposing the wealth tax while supporting a separate public school tax measure.
• The tax would raise up to $100 billion over five years, with 90% earmarked for healthcare.
• Opponents, backed by over $100 million from Sergey Brin, are funding rival measures to nullify the tax.
• Healthcare experts warn the one-time revenue may not prevent clinic closures or staff layoffs.

Background

Proposition 40 was placed on the ballot by a major healthcare union to offset $30 billion in annual federal cuts. Earlier polls showed a narrow lead, but rival measures designed to block the tax also polled above 50%. California’s Franchise Tax Board is preparing for unprecedented residency audits if the measure passes.

How outlets are covering it

Politico emphasizes the polling decline and the shift among independents, noting the campaign’s lack of funds. The New York Times highlights the aggressive opposition from billionaires, including Brin’s $100 million spending on rival measures. KFF Health News focuses on the uncertainty of the revenue’s impact, noting that healthcare experts doubt the one-time infusion will sustainably offset federal cuts or prevent clinic closures. While all sources agree on the tax’s potential scale, they differ on its viability: Politico and NYT focus on political opposition, while KFF questions the practical healthcare benefits.

Why it matters

The outcome of Proposition 40 could set a precedent for wealth taxes in other states, including Hawaii, Maine, and Massachusetts, which have already approved millionaire income taxes. A failure in California may dampen similar proposals nationwide, while a success could influence federal debates on wealth taxation. The measure also tests the limits of state power to tax ultra-wealthy residents amid federal budget cuts.

What to watch

Voters will decide on Proposition 40 and rival measures on November 3. If passed, the state must collect the tax, a process that could take months, and determine how to allocate the funds. Opponents are pushing for rival measures to pass, which could nullify the wealth tax even if it receives a majority of votes.
