Il Nuovo Postiglione - California billionaire tax appears headed to the ballot

The proposal gathered 1.5 million signatures -- nearly twice the number required to get on the ballot.

"Most Californians and most billionaires recognize how reasonable and necessary this proposal is -- both to keep emergency rooms open and to save California businesses from closing," Suzanne Jimenez of the Services Employees International Union-United Healthcare Workers West (SEIU-UHW), the measure's lead sponsor, said late Sunday.

Under the California Billionaire Tax Act, the state's wealthiest residents would be hit with a one-time tax of five percent of their net worth.

Some 90 percent of the tens of billions of dollars in expected revenue would be used to fund the state healthcare system for five years to offset the massive federal cuts imposed by President Donald Trump's budget law.

While the tax would be a one-off, the proposal has sparked controversy in the most populous state and across the nation.

Opponents fear it will scare off Silicon Valley and trigger an exodus of the ultra-wealthy, which would hurt tax revenue. California is home to more than 250 billionaires, more than any other US state.

The American left has been divided on the issue. Governor Gavin Newsom, a Democrat who is considered a potential 2028 presidential hopeful, opposes it, while progressive Senator Bernie Sanders is its chief supporter in Congress.

High-profile entrepreneurs are against it. According to US media, Google co-founder Larry Page, Oracle's Larry Ellison, and Palantir co-founder Peter Thiel have all taken steps to reduce their footprint in California.

And the cryptocurrency and artificial intelligence communities are funding ad campaigns against it.

Jimenez, the union leader, described the measure's wealthy opponents as "a very small group of the most controversial billionaires on the planet."

"Healthcare workers and our allies won't quit until we fully protect our patients from the looming healthcare disaster that will be caused by $100 billion in cuts to California healthcare," she added.

In the face of growing wealth inequality worldwide, taxation of the ultra-rich has become a flashpoint of debate in recent years.

Brazil put the idea of a billionaire tax on the G20 agenda when it hosted the forum's annual leaders' summit in 2024.

Last year France's parliament rejected the proposed 'Zucman tax,' a measure that would have taxed the ultra-wealthy at an annual rate of two percent.
