California billionaire tax qualifies for November 2026 ballot via signature drive

The California Billionaire Tax Act, now on the November 2026 ballot, is a one-time 5% tax on net worth above $1 billion, payable annually over three years. According to the Legislative Analyst's Office fiscal impact estimate (Dec. 11, 2025) and a detailed expert report from Saez, Gamage, and Shanske (2025), the measure would raise approximately $100 billion from roughly 200 California billionaires. Revenue would fund healthcare, education, and food assistance programs—a direct state-level response to the erosion of federal public investment. The measure's backers, including the SEIU-UHW union, argue that federal healthcare cuts alone are stripping $100 billion from California (citing a union-commissioned analysis), making this tax a necessary lifeline.

Opponents, including Governor Gavin Newsom and some business groups, warn of potential tax flight and interstate conflict. But the risk is not the tax itself—California's progressive tax base has long funded public goods while states like Florida rely on regressive sales taxes that fall hardest on low- and middle-income families. The genuine threat is the absence of federal coordination: a national wealth tax or anti-evasion safeguards (such as an exit tax or reciprocal information-sharing agreements) could prevent billionaires from relocating to low-tax states. In the absence of such federal action, states are left to patch a broken system. The progressive alternative is not to kill this measure but to pair it with federal reforms—closing the carried-interest loophole, taxing unrealized capital gains at death, and raising the corporate rate back toward 35%—to prevent a race to the bottom that weakens state revenue bases nationwide.
