Supporters of a proposed California tax on billionaires are taking their campaign to Washington, D.C., months ahead of a 2026 statewide vote. The push comes as a new poll shows just 30.5% of likely voters back the measure, signaling a steep climb for proponents.
Why the tax is being pushed in D.C.
The tax, which would apply to residents with a net worth of $1 billion or more, aims to raise billions for education, housing, and climate programs. Backers argue that the wealth gap demands a targeted levy on the state's ultra-rich. But the poll numbers suggest the idea hasn't yet caught on with a majority of Californians.
Lobbying federal lawmakers is an unusual move for a state ballot initiative. Supporters say they want to build national momentum and signal that the concept could spread. They're also hoping to preempt potential legal challenges that might hinge on federal tax law or interstate commerce.
What the poll reveals
The survey, conducted this month, put yes votes at 30.5%, with 45% opposed and the rest undecided. The margin is wide enough that proponents will need to shift a lot of minds before November 2026. The poll didn't break down the demographics of support, but the 30.5% figure is a starting point for a campaign that has two years to build a coalition.
Opponents point to the low number as evidence the tax is a nonstarter. They're already framing it as a job-killer that would drive billionaires out of state. The lobbying effort in Washington suggests supporters are worried about more than just the ballot box.
The legal and political landscape
Even if voters approve the tax, it's almost certain to face lawsuits. Opponents argue that a state-level wealth tax violates the U.S. Constitution's prohibition on direct taxes not apportioned among states. Supporters are exploring whether a federal endorsement or a change in federal law could inoculate the measure from such challenges.
That's why they're in D.C. now, meeting with congressional staff and tax policy experts. The goal is to lay groundwork for a federal workaround or a cooperative framework that lets California's tax survive. The 2026 vote is the immediate target, but the real fight may be in the courts and Congress.
With two years left until election day, the 30.5% support number is a cold splash of reality. Backers have time, but they'll need to convince a lot more Californians — and get Washington on their side — to pull this off.
