California’s proposed wealth tax is sending shockwaves through Silicon Valley, and it’s not just the 5% rate that has tech leaders up in arms. The real controversy lies in the fine print, which could upend the way founders control their companies—and it’s sparking a heated debate about innovation, fairness, and the future of the Golden State’s economy. But here’s where it gets controversial: the tax treats voting shares as if they represent actual wealth, potentially penalizing founders for maintaining control of their startups. And this is the part most people miss: it’s not just about taxing the rich—it’s about taxing influence, even if that influence doesn’t translate to cash in hand.
The proposed ‘billionaire tax’ doesn’t just target net worth; it goes after the voting power founders hold through dual-class stock structures. For example, Google co-founder Larry Page owns about 3% of the company’s shares but controls roughly 30% of its voting power. Under this tax, he’d be taxed on that 30%, not the 3% he actually owns. This raises a critical question: Is it fair to tax someone on control they wield but wealth they don’t possess?
‘The treatment of voting shares is so harsh, it’s hard to believe it was intentional,’ said Jared Walczak, a state tax expert at the Tax Foundation. ‘But the consequences are very real, even if unintended.’ This issue isn’t just theoretical—it’s already affecting tech founders who rely on dual-class stock to retain control, a practice that’s been central to Silicon Valley’s success. In fact, it’s one of the reasons Google’s Larry Page and Sergey Brin stepped down in 2019.
For startups, the tax introduces a nightmare of complexity. ‘Valuing a private company is inherently difficult,’ Walczak explained. ‘There’s no clear-cut method, and disagreements could lead to penalties—not just for the company, but for the individuals calculating those valuations.’ Joe Malchow, founding partner at venture capital firm Hanover, warns this could cripple young founders working on solutions to California’s biggest challenges, like energy shortages. ‘We’re already seeing the devastating impact,’ he said. ‘Founders are being taxed on phantom wealth—billions on paper, but not in their pockets.’
Take the case of a startup founded by SpaceX alumni, developing grid-forming technology to ease California’s energy burden. The founder holds voting shares representing 30% control of a billion-dollar company. Under the tax, he’d be hit with a bill based on that 30%, even though his actual economic stake is much smaller. ‘At the Series B stage, the tax would wipe out his entire holdings,’ Malchow added. ‘It’s like the 2008 housing crisis all over again—founders would be forced to walk away, and their employees would suffer the fallout.’
Garry Tan, head of Y Combinator, went viral this week for pointing out that Larry Page and Sergey Brin ‘can’t stay in California’ under the current proposal, which he called ‘poorly defined and designed to drive tech innovation out of the state.’ The tax won’t appear on the ballot until November, but it would apply retroactively to residents as of January 1, 2026. This has already triggered an exodus—since January, an estimated $1 trillion in wealth has left California, with reports that both Page and Brin have departed.
Not everyone is opposed. Nvidia founder Jensen Huang told Bloomberg TV he’d be ‘perfectly fine’ with the tax. But even left-leaning figures like Governor Gavin Newsom have vowed to stop it. ‘Founders value control of their businesses as much as, if not more than, their wealth,’ Walczak noted. ‘Taxing both? It’s a recipe for driving them out.’
Here’s the bigger question for you: Is California’s wealth tax a fair way to address inequality, or is it a misguided policy that risks killing the golden goose of innovation? Let us know in the comments—this debate is far from over.
