California's Proposed Billionaire Tax: A Lone Wolf Among States, Fueling Exodus Fears and Amplified Economic Fallout


A group has just passed legal review to begin collecting signatures to put a ballot measure directly to California voters to enact a "Wealth tax". The effort is being sponsored by a collective of labor unions, including the Service Employees International Union-United Healthcare Workers West, as well as Jim Mangia, President and CEO of St John's Community Health, the largest federally-qualified-health-center in South Los Angeles and beyond. Prior efforts to impose a wealth tax in California have repeatedly faltered in the state Legislature, where progressive proposals aimed at tapping the fortunes of the ultra-rich have died without reaching a full vote amid opposition from business groups, moderate Democrats, and even Gov. Gavin Newsom.


Prior attempts include Assembly Bill 2088 in 2020, which proposed a 0.4% annual tax on worldwide net worth exceeding $30 million ($15 million for married filing separately) and would have generated an estimated $7.5 billion annually, but it died without advancing to a vote. In 2021, AB 310 (tied to Assembly Constitutional Amendment 8) sought a 1% tax on net worth over $50 million, increasing to 1.5% over $1 billion, yet it also stalled before a full vote. More recently, AB 259 in 2023 aimed to impose a 1.5% tax on the "extremely wealthy" but was blocked in an Assembly tax committee in January 2024, aligning with opposition from Gov. Gavin Newsom and business groups.


Frustrated by these legislative dead ends, wealth tax proponents—led by labor unions are now attempting to bypass lawmakers entirely, turning to California's ballot initiative process to put the issue directly to voters. This push has ignited fierce backlash, with tech billionaires threatening relocation and economists warning of devastating long-term ripple effects—including massive revenue shortfalls, investment flight, and widespread job losses in the state's signature tech sector. Legislators now fear that the anti-rich zeal that they themselves have largely created within the citizenry will allow this measure to pass.


The "2026 Billionaire Tax Act," cleared for signature gathering, proposes a one-time 5% excise tax on net worth over $1 billion for individuals resident in California as of January 1, 2026, with valuations fixed at December 31, 2026. Exclusions for real estate and retirement accounts provide some relief, and payments can be deferred over five years (effectively around 1% annually with charges). Proponents project temporary revenues of tens to $100 billion, mainly to shore up health care funding against federal cuts - including health care for illegal aliens.

Proponents will begin collecting signatures to put the Wealth Tax on that ballot and put it to the voters.

Opposition is mounting for the current proposal, with Gov. Gavin Newsom fundraising to fight it and attorneys for unnamed billionaires issuing veiled threats of permanent departure.


California Stands Alone with This Latest attempt - Other Blue States have failed


No U.S. state currently levies a true wealth tax on net assets. Proposals in Hawaii (annual 1% on $20M+ net worth), New York, Connecticut, and others have stalled in legislatures without passage. Alternatives like high-income surtaxes or capital gains excises exist elsewhere, but California's one-time structure—narrowly targeting billionaires while capturing unrealized gains—makes it uniquely aggressive and immediate.


Amplified Economic Fallout: Beyond Taxes to Investment Flight and Job Losses

Critics contend the proposed wealth tax would accelerate California's wealthy out-migration, with consequences far exceeding the short term direct revenue benefits. The state's budget relies heavily on the top 1% of earners, who pay roughly 50% of personal income taxes, while the top 10% of earners pay 80%. The proposed tax specifically targets this segment. The current exodus of high-income taxpayers already costs $20-24 billion annually in lost adjusted gross income, compounding deficits and forcing service cuts or broader tax increases.


When billionaires leave, they take more than their tax bills:

  • Venture Capital Drain: Many tech titans are key investors; their relocation shifts funding to states like Texas and Florida, starving California startups of capital and slowing innovation in AI, biotech, and beyond.

  • Philanthropy and Spending Multipliers: Ultra-wealthy donations fuel universities, hospitals, and charities, while their luxury spending supports thousands of service jobs. Departure redirects these dollars elsewhere, hollowing out local economies.

  • Job Losses Cascade: Headquarters relocations since 2011 have already cost California an estimated 77,600 direct jobs. In 2025 alone, tech and related sectors saw over 173,000 announced layoffs amid restructuring and cost pressures—trends opponents say punitive taxes will worsen.


High-profile figures including Larry Page, Peter Thiel, Palmer Luckey, and crypto executives have signaled exit plans, warning the tax could "kill" emerging tech in California. Past moves like Tesla's and Chevron's headquarters shift to Texas underscore the risk of a tipping point, where lost investments, jobs, and talent erode Silicon Valley's dominance over decades. The California Legislature and Governor Newsom believe that risks suggested by opponents of the wealth tax could be well founded and could spell doom for California.


Proponents argue mass flight is overstated, citing billionaires' deep roots and "love" for California. Yet with no other state enacting similar measures and the deep blue legislature scared of it, this proposal risks turning short-term gains into permanent economic scars. Legal battles over unrealized gains and constitutionality loom if it passes. As signatures are collected, the stakes couldn't be higher: Will California gamble its innovation edge for equity—or will it become the final nail in the California coffin?
