California's Wealth Tax Proposal: What It Means for Expat Entrepreneurs

California is considering a one-time 5% wealth tax on billionaires, with a referendum scheduled for November 3. French economists Gabriel Zucman and Emmanuel Saez have publicly backed the proposal, arguing that the state's 250 billionaires have accumulated massive fortunes while paying minimal taxes. For expats and remote workers considering California as a relocation destination, this development raises important questions about tax exposure, cost of living, and the state's long-term fiscal direction.

Who Would Actually Be Affected?

The current proposal targets billionaires—individuals with a net worth of $1 billion or more. Most expats and remote workers won't meet this threshold. However, the referendum signals California's appetite for wealth-based taxation beyond income taxes, which already rank among America's highest. If the measure passes, it could set a precedent for lower wealth-tax thresholds in future years, eventually touching high-net-worth individuals with $50 million to $100 million in assets. Expats considering starting a business abroad in California should monitor this closely, as successful ventures could eventually expose them to new tax mechanisms.

California's Tax Environment for Remote Workers

California already imposes a 13.3% state income tax—the highest in the US—plus federal taxes. For remote workers earning six figures, the combined burden is substantial. A wealth tax, even if initially limited to billionaires, reflects the state's broader fiscal philosophy. Remote workers relocating to California should understand that the state views high-income earners as a primary revenue source. This contrasts sharply with lower-tax states like Florida, Nevada, and Texas, which attract expats specifically for tax advantages.

Broader Implications for International Relocation

The California proposal mirrors wealth-tax experiments in France, Switzerland, and Spain—countries where expat tax planning is a critical relocation factor. Global tax pressures on high earners are rising, and California's potential move signals that US states are adopting similar strategies. Expats should consider whether their long-term asset growth aligns with California's tax trajectory, or whether alternative US locations or international destinations offer better wealth-preservation strategies.
