California Proposes Revised Health-Plan Tax to Fund Medi-Cal Amid Federal Restrictions
By Drooid · · How we work
The Tax Proposal and Its Immediate Goal
California officials, led by Governor Gavin Newsom, have drafted a revised health-plan tax that would raise the levy on private insurers beginning in 2027, pending federal approval. The measure is intended to replace the existing financing mechanism that will become unavailable after 2026 under the federal One Big Beautiful Bill Act, which limits the use of health-plan taxes to draw federal matching funds for Medicaid (Medi-Cal).
Background and Context
Medi-Cal covers roughly one-third of Californians—about 13.6 million people—and accounts for more than 40 percent of the state’s budget, according to the Legislative Analyst’s Office. Spending rose from $50 billion in 2010 to $222 billion today. A 2025 Associated Press estimate placed the cost of providing health care to immigrants without legal status at $12.4 billion.
The One Big Beautiful Bill Act is projected to cut federal Medicaid spending by over $900 billion nationwide over ten years, forcing states to find new revenue sources or reduce benefits. California’s existing health-plan tax, which previously targeted only Medicaid enrollment, would violate the new federal rules after 2026, prompting the redesign.
Official Statements and Responses
- H.D. Palmer, deputy director for external affairs at the California Department of Finance, explained that the proposal includes two tracks: one mirroring the current scheme (which may conflict with federal law) and another that complies by shifting costs to private plans. He added that if the federal government declines approval, Proposition 35 could sunset under current law.
Criticism and Opposition
The California Medical Association and the California Association of Health Plans have filed a lawsuit alleging that the revised tax violates voter-approved limits on health-plan taxes and restricts how revenue may be spent. Their challenge is notable because doctors and insurers, who usually oppose each other, are aligned against the tax.
Republican gubernatorial candidate Steve Hilton has called coverage for undocumented immigrants “wildly unsustainable” and argued that the safety-net role should be limited to the poorest residents.
Conflicting Reports and Gaps
- Premium impact: Insurers estimate an average increase of $100 per person annually, while the Fox News piece also cites a $400 per family rise. Both figures are projections; actual effects will depend on federal approval and market responses.
- Legal outcome: The lawsuit’s resolution is pending, and the courts have not yet ruled on whether the tax violates Proposition 35.
- Federal approval: The One Big Beautiful Bill Act’s implementation timeline leaves uncertainty about when, or if, the revised tax will be authorized.
What’s Next
The revised tax proposal will be submitted for federal review, with a decision required before the 2027 implementation date. If rejected, Proposition 35 could automatically sunset, potentially eliminating the state’s ability to raise additional health-plan revenue. The lawsuit is scheduled for judicial review, and a court ruling could determine whether the tax proceeds. Stakeholders are watching the outcome closely, as it will shape California’s capacity to fund Medi-Cal amid escalating costs and federal constraints.
