California labor union offers to scale back billionaire tax proposal after pushback

Tara Gallegos, a spokesperson for Newsom, said scaling it back doesn't change its "fundamental flaws that harm working Californians.”

“The Governor supports making the wealthiest Americans pay their fair share, but this poorly designed state-only measure will defund teachers, schools, clinics, and public safety,” she said in a statement.

The tax, to be paid by those living in the state as of Jan. 1, 2026, is meant to generate $100 billion in revenue, mainly to counter federal cuts to healthcare for low-income people with some money going to food assistance and education programs.

“A 2% one-time tax on that accumulated wealth is modest by any objective measure especially if it means keeping emergency rooms open and saving patient lives,” backers wrote in a letter to Newsom.

Secretary of State Shirley Weber, a Democrat, said Wednesday night that petitioners collected more than the roughly 875,000 signatures needed to place the original proposal before voters.

States have been debating how to respond to the major tax breaks and spending cuts legislation President Donald Trump signed last year. The proposal has already divided Democrats and major labor unions and triggered an expensive campaign to defeat it. The proposed tax is backed by prominent progressives including Vermont Sen. Bernie Sanders.

Silicon Valley tech moguls have spent millions to defeat it, and prominent players in Sacramento have opposed it. They include the California Medical Association and California School Boards Association, which helped launch a committee this week urging voters to reject it if it ends up on the ballot in November. Newsom also opposed a ballot measure in 2022 to increase taxes on the wealthy, which would have funded programs that help people buy electric cars or install more chargers. Voters rejected it.

Critics say the original measure would decrease state revenue over time by pushing the ultrawealthy to leave, taking the money they would contribute in income taxes with them. That would deal a huge blow to a state that relies on its top 1% of earners for nearly half its personal income tax revenue.

“This flawed measure is the wrong approach for California’s small businesses and working families,” said Roger Salazar, a spokesperson for Golden State Promise, a political committee fighting the tax.

The nonpartisan Legislative Analyst’s Office estimates that the 5% tax would generate tens of billions of dollars in the first few years, but that income tax revenues could subsequently decline by hundreds of millions of dollars annually.

Since the proposal was announced in October, Google co-founder Sergey Brin has donated $82 million to a political committee called Building a Better California that backs a variety of initiatives designed to blunt the billionaire tax proposal. It has raised more than $118 million, counting Brin’s contributions, from fewer than a dozen donors.

State lawmakers passed budget bills this week that aim to raise revenue in other ways, including by extending a tax on healthcare providers. Newsom and legislative leaders agree to this approach, Senate President pro Tempore Monique Limón said.

“The budget, as approved by the Legislature and now being negotiated with the Governor, does not include the billionaire’s tax,” the Democrat said in a statement. “Instead, it reflects additional revenues to address our long-term structural deficit.”
