California’s Wealth Tax Promises a Medi-Cal Fix. Doctors Aren’t Buying It.

California’s 2026 Billionaire Tax qualified for the November ballot on June 17. It’s being sold as a healthcare rescue. The mechanism is more complicated than that pitch suggests.

The initiative creates a special fund — the 2026 Billionaire Tax Reserve Fund — that is constitutionally separate from the General Fund and cannot be borrowed against or swept into it. The Legislature then appropriates the money, up to $25 billion a year, deciding which eligible programs and providers receive it and on what timeline. The measure requires that 90% be spent on health care, and it bars the money from supplanting existing state health funding. What it does not include is any formula guaranteeing dollars to a particular hospital or clinic. If you run a clinic trying to plan a budget, an annual legislative appropriation is not the same thing as a dedicated funding stream.

That uncertainty is part of why the California Medical Association opposes the measure, along with the California Primary Care Association and Planned Parenthood Affiliates of California. These aren’t anti-tax groups. They’re among the providers the measure claims to rescue. The California Medical Association has argued the tax is a one-time levy that won’t provide sustainable, long-lasting funding for a recurring shortfall. Planned Parenthood has objected that the initiative does not clearly lay out how the revenue would be spent. The California Teachers Association also opposes it, as do organizations representing law enforcement, carpenters, and builders.

What the initiative does do is route tens of billions into a fund whose year-to-year distribution the Legislature controls. The measure also permits the Legislature to amend the act by a two-thirds vote, provided the changes are consistent with its purposes. Opponents such as the California Business Roundtable argue that provision could be used to alter the tax over time; the union disputes that reading. Either way, the healthcare crisis is real, and the question critics raise is whether this is the right vehicle to address it.

The LAO Report

The nonpartisan Legislative Analyst’s Office reviewed the measure on December 11, 2025. Its conclusions were careful, and they cut both ways.

On revenue: the state “probably would collect tens of billions of dollars” from the one-time 5% tax on California billionaires’ net worth — not the $100 billion supporters project. The LAO flagged that the figure is hard to pin down, because it depends on stock valuations and on how aggressively billionaires restructure to minimize what they owe.

On the downside: the LAO found a “likely ongoing decrease in state income tax revenues of hundreds of millions of dollars or more per year.” The mechanism is straightforward. Some billionaires leave. The income taxes they currently pay go with them. That loss is permanent; the wealth tax revenue is temporary.

The LAO’s summary of major fiscal effects captured the core tension: a one-time gain of “tens of billions” spread over several years, set against a permanent reduction in the income tax base.

The Healthcare Case

The measure’s proponents are not wrong about the crisis they’re describing.

The One Big Beautiful Bill Act (H.R. 1) cut federal Medicaid funding in ways that hit California hard. Independent analyses — by the California Budget and Policy Center and by researchers at UCLA and UC Berkeley — estimate the law will reduce federal contributions to Medi-Cal by roughly $30 billion a year, about a quarter of the program’s federal funding. Because of the federal matching formula, fully replacing that with state dollars would cost California on the order of $15 billion a year. Medi-Cal covers nearly 15 million Californians, including more than half of the state’s children and 2.2 million seniors and people with disabilities.

The initiative’s own findings are explicit: Medi-Cal is projected to lose up to $19 billion in annual federal funding, with cumulative cuts over ten years of approximately $190 billion. State cuts to Medi-Cal are estimated to reach $7 billion in 2027-28, rising to $8.6 billion each year from 2028-29 onward.

Under the initiative, 90% of the revenue goes to a Health Account for Medi-Cal and other health programs, and 10% to an Education and Food Assistance Account that covers K-14 public education and programs such as CalFresh. The Legislature would control allocation, with up to $25 billion available annually.

Why Doctors Oppose It

The California Medical Association opposes the measure. So does the California Primary Care Association. So does Planned Parenthood Affiliates of California.

These are not right-wing anti-tax organizations. They are providers who would actually spend the money the tax would generate. The California Teachers Association also opposes it, as do organizations representing law enforcement, carpenters, and builders — a coalition that rarely lines up together in California politics.

Jason Elliott, Newsom’s former deputy chief of staff, described the breadth of the opposition: “The proponents ought to hope that negotiations are successful because they have given birth to one of the most unpopular measures I’ve seen in years.”

The objections tend to share a theme. The funding is one-time, against a shortfall that recurs every year. The measure leaves discretion over allocation to the Legislature rather than to the healthcare system, and it doesn’t spell out precisely how the money reaches providers. For groups trying to plan multi-year budgets, those are real concerns — even setting aside the worry that the tax could drive wealthy residents, on whom the state budget leans heavily, out of California.

What the Negotiation Reveals

On June 18, the day after the measure qualified, SEIU-UHW sent Newsom a letter offering to drop the 5% ballot measure if he would back a smaller 2% levy passed through the Legislature. Proponents face a June 25 deadline to pull the initiative from the ballot. So a measure framed as an urgent healthcare rescue proved negotiable by more than half its headline rate within roughly a day of qualifying.

The coalition’s letter framed the 2% version as a “two-year bridge” while the state develops longer-term funding. Which raises a fair question: if a two-year bridge would suffice, what was the larger version meant to accomplish? Newsom rejected the revised offer.

What Passes or Fails

If the measure goes to the ballot and passes, California will have created a special fund worth tens of billions, legally reserved 90% for health care and walled off from the General Fund, but distributed at the Legislature’s discretion year to year — with no guarantee to any specific provider, and as a one-time infusion rather than ongoing support. Whether that meaningfully stabilizes the providers in crisis depends on how the Legislature appropriates it. The measure will also likely face legal challenges over its retroactive design, which could tie up the revenue for years.

If it fails, the underlying crisis remains. Federal cuts to Medi-Cal are real, and California has no other large-scale alternative funding mechanism on the table. Proponents have been right about the problem; the disagreement is over the solution, and that gap will outlast the June 25 deadline regardless of what happens next.

The LAO’s December analysis captured the core tension plainly: a temporary revenue gain, set against a permanent reduction in the income tax base. Defenders and critics largely agree on the problem. They disagree on whether a one-time wealth tax, which risks cutting California’s tax base in the long-term, is the right way to meet a shortfall that recurs every year.
