California Governor Gavin Newsom wants the federal government to tax billionaires. He does not want his own state to do it first. The Democrat posted a plan Friday on Substack calling for a national “true minimum tax on billionaires.” The idea is simple: make the ultrawealthy pay at least the same tax rate as their employees.
It echoes what billionaire investor Warren Buffett has long called the “Buffett Rule.” Newsom also wants Congress to reverse corporate tax cuts from the Trump era. He wants tighter inheritance rules.
He wants to kill what he calls a “tax-free lifestyle loan” strategy — that trick where rich people borrow against their assets instead of selling them, avoiding taxable income. Then there is the “national public equity fund.” Every American, Newsom says, would own a stake in the future built by artificial intelligence. But watch what happens next.
The governor is simultaneously fighting a California ballot measure that would slap a one-time 5% wealth tax on billionaires in his own state. He says it would drive money and people to other states.
“Wealth is movable, and it shops for the state with the lowest taxes,” he wrote, per the Guardian. These battles, he argued, should not be waged “state by state.” The fallout is already clear. Newsom is betting big on federal action.
That bet may not pay off. Congress is deeply divided. A national billionaire tax faces steep odds.
Meanwhile, the California measure could still pass without his support. If it does, and if the wealthy actually leave, the state loses revenue.
If it fails, and nothing happens in Washington, the whole thing fizzles. Newsom is walking a tightrope. He wants the populist energy around taxing the rich.
He wants to lead a progressive economic reset. He just does not want to own the consequences if it backfires on California alone.
That is the careful balancing act here. The governor is positioning himself for a national audience. This is about more than tax policy.
It is about his future. The Substack post and video are aimed beyond Sacramento. They are aimed at voters in Iowa, New Hampshire, and everywhere else.
The message is: I am the guy who will take on billionaires — but I am smart enough to know you cannot do it state by state. Critics will call it hypocrisy.
Supporters will call it pragmatism. Either way, the stakes are high. If the federal tax never materializes, Newsom has nothing to show for the rhetoric.
If it does, he can claim credit for starting the conversation. The California ballot measure is the wild card.
It forces his hand. He has to oppose it without looking like a friend of billionaires. The practical effects touch everyone.
A national billionaire tax could reshape how the ultrawealthy manage their money. It could close the borrowing loophole that lets them live tax-free. It could fund the AI equity fund Newsom wants.
Or it could do nothing at all, if Congress ignores it. What to watch next: the California ballot measure.
That vote will test whether voters agree with their governor. If they pass it anyway, Newsom faces a real problem. If they kill it, he survives — but the national conversation keeps going.
This is not over. It is just the opening move.
