California’s Wealth Tax “Safeguards” Are a Trap

The bill’s architects say founders can fight the state for their money back. With interest. On hard mode.

TL;DR

California’s proposed wealth tax shifts the burden onto founders: the state takes your money first, then you fight to get it back through bureaucratic nightmares with interest piling up.

The Atlantic just published a deep dive on California’s proposed wealth tax, framing it as a “risky bet.” That’s an understatement. The real story is how the bill’s architects designed “safeguards” that aren’t safeguards at all—they’re bureaucratic nightmares that take your money first and force you to fight the DMV equivalent to get it back.

The “Safeguards” Are a Trap

The bill’s defenders love to tout its protections. Don’t like how the state valued your startup? Bring in “independent appraisers” to argue with them. Can’t pay 5% of your paper wealth right now? They’ll put you on a five-year payment plan. With interest.

Contrary to what its opponents claim, moreover, the tax is carefully designed to avoid the most common objections. If billionaires are worried that the government will improperly value their assets, they can submit independent third-party appraisals. If they can't come up with the full 5 percent all at once, they can spread out payments over five years, though they would be charged interest. If their fortunes are tied up in "illiquid assets" such as a pr...

This isn’t protection—it’s a shakedown. The state takes the money, and you get to spend years and hundreds of thousands in legal fees trying to prove they got it wrong. And if your fortune is tied up in illiquid startup equity? You can “defer” the tax—meaning you still owe it, it’s still hanging over your head, and you’re still trapped.

That’s Brian Galle, a UC Berkeley law professor who helped write the bill. Classic zero-sum thinking: founders explaining real liquidity constraints are just greedy liars. Never mind that a unicorn founder at $5B valuation owes $100M while having zero ability to sell shares.

The Real Exodus Has Already Begun

The billionaire flight isn’t hypothetical—it’s happening right now. Google co-founder Larry Page and PayPal co-founder Peter Thiel made moves to leave California before the end of 2025. Teddy Schleifer reported that Sergey Brin terminated or moved 15 California LLCs in the 10 days before Christmas 2025.

Why the rush? The tax is retroactive to January 1, 2026. If you were a California resident on that date, you owe it—no matter where you move afterward. The bill’s designers thought this was clever: a trap that prevents flight. Instead, it just accelerated the exodus.

The Atlantic notes that Andy Fang, DoorDash co-founder, said the tax “could wipe me out” and that it would be “irresponsible for me not to plan leaving the state.” Jensen Huang and Brian Chesky say they’ll stay—but when Google’s co-founders are already out the door, that’s cold comfort.

22-Year-Olds Get the Message

Startups don’t just “flow” to other states. They stop getting created here in the first place. If the message is “California is a dangerous place to be rich,” every ambitious 22-year-old hears: don’t build the next great company in California at all.

YC averages 2-4 unicorn founders per year who would hit this tax threshold. That’s 2-4 future paper billionaires who, if they build in California, will instantly owe the state $100M+ while being completely illiquid. The math is brutal and the message is clear.

Austin is the only major hub increasing its share of VC funding—up 63% in 2025 versus 2024. The next wave of great companies doesn’t have to start in California. And increasingly, they won’t.

Zero-Sum Thinking vs Abundance

The tax’s designers operate in a zero-sum world where wealth is finite and must be redistributed. Two people in a garage can’t possibly create something from nothing. But California startups have always been abundance-generating—they create value that didn’t exist before.

For proponents of the proposal, going forward with the wealth tax is worth the risk, if only because the alternative is so much worse. Better to lose a handful of billionaires than for millions of low-income Californians to lose their health care. Other ways to generate the same revenue—such as raising income or corporate taxes, or cutting other parts of the budget—come with their own set of hard economic, political, and moral trade-offs. There is also a...

David Sacks nailed the fear: “It’s not a one time; it’s a first time. And if they get away with it, there’ll be a second time and a third time.” He’s not wrong. In 2012, California voters approved a “temporary” income tax hike that’s been extended twice and will likely never go away.

Polymarket gives the wealth tax a 31% chance of passing. That’s not nothing. If you care about California’s future as an innovation hub, this fight matters. The architects of this bill view founders as adversaries to be squeezed, not partners in building abundance. That worldview—if enshrined in law—will send a clear message to the next generation of builders: go somewhere else.
