California Billionaire Tax Faces Polling Deficit
Proposition 40 trails in recent polls, while a competing measure could void the tax if it wins more votes.
By Aiko Soto ·

California voters decide on November 3 whether to impose a one-time 5% tax on residents with net worth exceeding $1 billion.
Proposition 40 requires a simple majority to pass. The measure targets approximately 250 individuals in the state. It is the first state-level tax on net worth.
Recent data from the Public Policy Institute of California shows the initiative falling behind. The latest figures indicate that 46% of voters support the measure, while 52% oppose it. This result contradicts early predictions by political analysts that the tax would win easily given its narrow target group.
Supporters attribute the shift in public opinion to a $300 million advertising campaign. Tech billionaires and business groups funded this effort. The ads warned that the state legislature could expand the tax to ordinary Californians using a two-thirds vote.
A separate ballot measure, Proposition 42, presents a structural obstacle. If Proposition 42 receives more votes than Proposition 40, it acts as a poison pill. This outcome would nullify the billionaire tax.
Proposition 42 proposes a permanent ban on statewide taxes imposed on the property of all Californians. The measure specifically targets personal property and retroactive taxes. The official ballot language prohibits new state taxes on the ownership of personal property, a category that includes assets other than real estate.
The California Voter Information Guide outlines the arguments for and against Proposition 42. The guide states that a yes vote protects residents from double taxation on personal property, including retirement and savings accounts. The no side describes the measure as a billionaire-funded trick.
Both Proposition 41 and Proposition 42 were created by Building a Better California. This political action committee is funded by tech executives and California billionaires who oppose the billionaire tax. Jared Walczak of Walczak Policy Consulting notes that both competing measures have the potential to win majority support. He stated that the dynamic creates a complex scenario where the billionaire tax faces stiff challenges from measures designed to protect individual financial assets.
