California wants to tax the ultra-rich. But the ultra-rich are fighting back—hard.
In a dramatic escalation, celebrity lawyer Alex Spiro—known for representing Elon Musk, Jay-Z, and other A-listers—has sent a formal letter to Governor Gavin Newsom urging him to block the proposed **California wealth tax**, warning it could trigger a “destructive exodus of capital, talent, and innovation” from the state .
The target? The so-called “Billionaire Tax Act,” a ballot initiative that would impose a **one-time 5% tax on net wealth exceeding $1 billion**. Backers say it could raise $50 billion for housing, education, and climate programs. But Spiro and his clients argue it’s not just bad policy—it’s unconstitutional, economically reckless, and potentially catastrophic for California’s global standing.

What Is the California Wealth Tax Proposal?
Officially titled the “California Billionaire Tax Act,” the initiative would levy a **one-time 5% tax on the net worth of individuals or trusts with assets valued above $1 billion**, as of December 31, 2025 .
Key features:
- Applies to worldwide assets of California residents
- Payment can be spread over 10 years (with interest)
- Revenue earmarked for affordable housing, public schools, and wildfire resilience
- Requires voter approval via 2026 ballot
Proponents, including Senator Scott Wiener and advocacy group “Make Big Pay,” argue it targets a class that has “gamed the system” for decades while homelessness soars in Silicon Valley and Los Angeles.
Alex Spiro Enters the Fray
But in a sharply worded letter obtained by media outlets, Spiro—partner at Quinn Emanuel and legal counsel to some of the world’s wealthiest individuals—pulled no punches .
“Our clients have made it clear: they will not stay in a state that treats success as a crime. Forcing the sale of illiquid assets like private companies, art, or real estate to pay a confiscatory tax is not governance—it’s vandalism.”
Spiro warned that the tax would violate the **U.S. Constitution’s Due Process and Equal Protection clauses**, as well as the **Commerce Clause**, by retroactively taxing non-California assets of residents who may soon relocate.
California Wealth Tax: Constitutional Questions
Legal scholars are divided, but many agree: a wealth tax is uncharted territory.
The U.S. has never implemented a direct federal wealth tax. The Supreme Court has only addressed income taxes (via the 16th Amendment). A wealth tax could face immediate legal challenges on two grounds:
- “Direct tax” issue**: If deemed a direct tax, it must be apportioned by state population—making it impractical.
- Valuation arbitrariness**: How do you fairly value a private startup or a Picasso? Forced sales could destroy value, triggering economic harm beyond the taxpayer.
As Harvard Law professor Laurence Tribe noted, “Wealth taxes are legally fragile. California is walking into a minefield” .
The Exodus Threat: Real or Rhetoric?
Skeptics dismiss the “exodus” warning as fearmongering. But data suggests it’s real.
Since 2020, California has lost more high-earners than any other state:
- Over **8,000 millionaires** relocated between 2020–2024 (Henley & Partners Report)
- Texas, Florida, and Nevada saw the largest inflows—states with no income or wealth taxes
- Tesla moved HQ to Texas; Oracle and HP Enterprise already left
As venture capitalist Marc Andreessen tweeted: “Tax creators, and creation leaves.”
Who Really Pays When Assets Are Illiquid?
Many billionaires are “asset-rich, cash-poor.” Elon Musk’s net worth is ~$250B, but most is tied to Tesla stock. Forcing a $12.5B tax bill could mean:
- Selling massive stock blocks, crashing share prices
- Fire-selling private assets at discounted rates
- Layoffs at startups needing liquidity
Ironically, the very workers the tax aims to help could suffer collateral damage.
Economic Ripple Effects Beyond Billionaires
California’s economy isn’t just beaches and tech. It’s:
- 40% of U.S. venture capital investment
- Home to 125+ unicorns
- Leader in green tech, biotech, and entertainment
If innovation hubs migrate, so do high-paying jobs, tax revenue from capital gains, and philanthropy. The state could end up with **less total revenue**—not more.
Political Battle Lines Drawn
Governor Newsom hasn’t endorsed the tax but hasn’t blocked it either. With a 2026 ballot likely, both sides are gearing up:
- Pro-tax coalition**: Unions, housing advocates, progressive Democrats
- Anti-tax coalition**: Tech CEOs, investors, legal heavyweights like Spiro
For Newsom—who has national ambitions—the vote is a tightrope walk between populist appeal and economic pragmatism.
Conclusion: A Tax or a Tipping Point?
The **California wealth tax** isn’t just policy—it’s a referendum on the state’s identity. Can it balance social justice with economic realism? Or will it accelerate the very decline it seeks to fix?
As Spiro’s letter makes clear: in the war for global talent, tax policy is a weapon—and California may be aiming it at its own feet.
