California Billionaires Are Freaking Out Over a New Tax Proposal

What It Covers

California's health care workers union proposes a one-time 5% wealth tax on residents worth over $1 billion to replace $100 billion in federal Medicaid cuts. The measure triggers backlash from tech billionaires and raises questions about the state's relationship with its wealthiest residents.

Key Questions Answered

• •Wealth Tax Mechanics: The proposal taxes total asset value rather than income or realized gains, requiring auditors to value privately held stocks, artwork, intellectual property, and company voting rights—a departure from traditional U.S. taxation that only taxes assets when they change hands or generate income.
• •Revenue Concentration Risk: California derives one-sixth of its total tax revenue from the top 0.1% of earners as of 2023. The proposed tax affects approximately 200 billionaires statewide, making the state's budget vulnerable to wealthy residents relocating and creating tension between progressive policy goals and fiscal stability.
• •Residency Verification Complexity: California uses 19 factors to determine residency for tax purposes, including real estate holdings, artwork location, wine collection storage, voter registration, country club memberships, religious affiliations, veterinarian choice, phone call origins, and toll pass records—making it difficult but not impossible for billionaires to prove they've left.
• •Political Coalition Dynamics: The Save California signal chat united politically opposed tech elites like Trump's AI czar David Sachs and Democrat Chris Larson against the tax. Governor Gavin Newsom opposes the measure, launching the Stop the Squeeze PAC, demonstrating how wealth taxation crosses traditional partisan divides and creates unusual alliances.
