California’s Prop 40 proposes a one‑time 5% wealth tax on billionaires
The measure, backed by the SEIU‑UHW union, faces criticism that it could become a broader tax burden for all Californians.

California’s Proposition 40, slated for the November ballot, would impose a one‑time tax of 5% on the net‑worth of residents whose assets exceed $1 billion, according to Fortune. The Service Employees International Union‑United Healthcare Workers West (SEIU‑UHW) argues the levy could generate about $100 billion in revenue, helping offset recent federal cuts to health‑care spending.
The proposal also includes a clause allowing the state legislature to amend the measure with a two‑thirds vote, but only if any changes are consistent with the 2026 Billionaire Tax Act. Proponents maintain the tax is narrowly targeted at billionaires, while opponents warn it is a “Trojan horse” that could eventually be broadened to affect all taxpayers.
Historical context shows California’s tax base is heavily weighted toward its wealthiest residents. The Hoover Institution reports that the top 1% of households have contributed roughly 40‑50% of personal income‑tax revenue in recent years, paying more than $60 billion in 2021 when the stock market was strong. This concentration makes the state vulnerable to fiscal shortfalls during market downturns, such as the Great Financial Crisis.
Legal experts note that California’s courts have previously ruled on the scope of ballot‑measure amendments. In 1995 the state Supreme Court allowed changes that furthered the original intent, whereas a 2019 decision by the Third District Court of Appeal rejected an amendment that conflicted with a law’s primary purpose. These precedents suggest that any post‑approval modifications to Prop 40 could be subject to judicial review.
Support for the initiative includes a group of Nobel‑laureate economists who claim the measure could spark a national movement toward wealth taxation. Critics, however, caution that the language allowing legislative tweaks could enable future expansions beyond the intended billionaire cohort, potentially impacting all Californians.
