Nationwide: Tax Them Everywhere—Except California?

California Governor Gavin Newsom is pushing a national billionaire tax while fighting the same idea at home, and that contradiction is hard to miss.

Quick Take

Newsom first pitched a **minimum tax** for people with more than **$100 million** in net worth.^[16]
He also wants tighter rules on **inheritance**, stock-backed borrowing, and corporate tax rates.^[1]^[4]
He is opposing a California billionaire tax while calling for a federal version.^[2]^[5]
Critics say the move looks like a **political maneuver** tied to a possible presidential run.^[4]^[16]

Newsom’s National Pitch Targets Wealth, Loans, and Inheritance

Newsom’s Substack post laid out a broad plan aimed at the ultra-rich. He called for “a true minimum tax on billionaires” and, in earlier versions of the pitch, said it would apply to people with net worth above $100 million.^[1]^[16] The plan also targets the practice of borrowing against stock holdings without paying tax on gains. Newsom said that loophole lets the wealthy fund luxury lifestyles tax free.^[2]^[4]

He went further by linking the tax plan to inheritance rules. Newsom warned that the country faces a massive intergenerational wealth transfer and said it could lock in a “permanent American aristocracy.”^[1]^[4]^[5] He also called for restoring corporate tax rates to pre-2017 levels and creating a national public equity fund tied to artificial intelligence gains.^[1]^[5] Supporters present the plan as a way to spread wealth. Opponents see it as a new layer of federal control.

The California Fight Exposes the Political Contrast

The sharpest part of the story is Newsom’s posture in California. He is trying to stop a state wealth tax while promoting a national one, which gives critics an easy case to make about double standards.^[2]^[5]^[6] The California proposal would hit billionaires with a one-time 5 percent wealth tax, and the state’s Legislative Analyst Office says the governor cannot veto a ballot measure if voters approve it.^[18] That legal detail matters, because it shows why Newsom is campaigning against the state plan instead of simply blocking it.

Newsom has defended his position by arguing that wealthy people can move to dodge state taxes, while a federal system would be harder to escape.^[4]^[5] That is the central logic behind his pitch. But the same argument also reveals the weak point. A federal tax still depends on enforcement, and the proposal does not yet spell out a full rate or detailed enforcement plan.^[4] Without that, the policy reads more like a slogan than a finished law.

Why Conservatives See a Bigger Warning Sign

For conservatives, the bigger issue is not only the tax itself. It is the larger push for government to decide who counts as too rich, how family wealth is passed on, and how private capital should be redirected. Newsom’s own language frames inherited wealth as a threat to democracy, not a normal part of family life.^[1]^[5] That is the kind of thinking that makes many voters worry about creeping government overreach and an ever-growing federal role in private property.

The political timing also matters. Multiple reports note that Newsom is seen as a potential presidential candidate, and his national tax pitch came as the California ballot fight heated up.^[4]^[16] His critics argue that this makes the plan look like positioning for 2028 rather than a serious attempt to write tax law. Even some Democrats are split on wealth taxes, and California’s own fiscal warning says the state plan could cost hundreds of millions a year if billionaires leave.^[18] That is the kind of reality check opponents will keep using.
