A California ballot initiative proposing a 2% tax on the wealth of billionaires to backfill state healthcare funding has cleared its first major hurdle, with proponents submitting more than 1.1 million signatures to the secretary of state’s office on Monday, exceeding the 906,000 required to qualify for the November ballot.
The measure, dubbed the California Billionaire Tax Initiative, would impose an annual levy on individuals with a net worth exceeding $5 billion, with revenues earmarked for Medi-Cal, the state’s Medicaid program, which serves over 14 million low-income residents. Supporters say the tax would generate an estimated $10 billion annually, according to an analysis by the California Budget & Policy Center, a nonpartisan research group.
Proponents, including the California Nurses Association and Service Employees International Union, framed the effort as a direct response to the state’s ongoing budget shortfalls and rising healthcare costs. “This isn’t about punishing success—it’s about ensuring every Californian has access to healthcare, regardless of their zip code,” said Ronnie Cohen, president of the California Nurses Association, in a statement. The initiative’s backers argue that billionaires have benefited disproportionately from economic policies while public services face chronic underfunding.
Opposition from business groups and some lawmakers has been swift. The California Chamber of Commerce warned the tax could drive wealthy individuals and businesses to other states, citing a 2023 study by the Tax Foundation that found high-income taxpayers often relocate in response to wealth taxes. “This is a reckless proposal that will harm our economy at a time when we need investment, not disincentives,” said Kristin Clarke, the chamber’s vice president of tax policy.
While the secretary of state’s office has until July 15 to certify the signatures, legal challenges from opponents are expected. A similar 2020 ballot measure, Proposition 15, which sought to tax commercial and residential properties, was tied up in court for months before ultimately failing at the polls. The current initiative’s sponsors have already preemptively filed arguments in Alameda County Superior Court to block any objections over signature validity.
Why the healthcare funding gap matters
California’s Medi-Cal program faces a $1.2 billion shortfall in the current fiscal year, according to the California Department of Health Care Services. The initiative’s proponents point to a 2024 Legislative Analyst’s Office report that found the state’s general fund has struggled to keep pace with rising healthcare costs, particularly for elderly and disabled populations. Meanwhile, the state’s 100 wealthiest residents saw their collective net worth increase by $120 billion between 2020 and 2023, per data from the Institute on Taxation and Economic Policy.
The debate over the billionaire tax has also reignited discussions about progressive taxation in the U.S., with comparisons drawn to New York’s 2021 millionaires’ tax, which generated $1.7 billion in its first year but faced legal challenges from high-net-worth individuals. In California, where Proposition 13 caps property taxes, wealth taxes have historically faced strong resistance from conservative lawmakers and business lobbies.
What happens next if the initiative qualifies
If certified, the initiative would appear on the November ballot as a standalone measure, separate from other state propositions. Polling suggests it could face an uphill battle: a Sacramento Bee/UC Berkeley Institute of Governmental Studies survey from May found only 38% of registered voters supported a wealth tax, with opposition highest among Republicans and independent voters. However, supporters note that similar measures have gained traction in recent years, including Colorado’s 2023 ballot initiative to fund education through a tax on millionaires, which passed with 56% approval.
The secretary of state’s office has not yet indicated whether it will accept the signatures or refer the matter to court. Legal experts say the process could take weeks, with a final decision likely before August 1. In the meantime, healthcare advocates are ramping up outreach, while business groups have launched a $5 million ad campaign warning of economic consequences.
The initiative’s fate hinges on two key factors: whether the signatures meet legal standards and whether voters perceive the healthcare funding crisis as urgent enough to override concerns about economic impact. With Medi-Cal enrollment projected to grow by 1.5 million over the next decade, the debate over how to finance the program has become one of the most contentious in California politics.
