California health-plan tax draws lawsuit over Medi-Cal costs and premiums
California Gov. Gavin Newsom and Democratic lawmakers backed a revised tax on private health plans to preserve Medi-Cal funding after federal restrictions tightened. Doctors and insurers are suing, arguing the plan violates Proposition 35 and could raise premiums for privately insured residents. The debate comes as California spent an estimated $12.4 billion in 2025 on healthcare for immigrants without legal status, according to the Associated Press.
California’s existing health-plan tax structure cannot continue after 2026 under federal changes, prompting a redesign. The proposed levy would apply to private plans starting in 2027 if federal officials approve it.
The California Medical Association and California Association of Health Plans have challenged it, saying it conflicts with Proposition 35, which voters approved to cap taxes on commercial enrollment. The dispute centers on financing Medi-Cal, not directly on coverage for immigrants without legal status. AP estimated California spent $12.4 billion in 2025 on such care.
If the revised tax takes effect, privately insured Californians could face higher premiums, while Medi-Cal recipients may see funding preserved. Doctors and insurers may absorb administrative or legal uncertainty as the lawsuit proceeds. The outcome could shape how states respond when federal rules constrain health-plan taxes, with implications for coverage, provider payments, and state budgets.
