Election Day
California voters will decide on the billionaire tax alongside two other tax measures.
Assembly Republicans Send Letter to HHS
A group of California Assembly Republicans formally asks the federal Health and Human Services Secretary to intervene against the MCO tax, calling it a burden on families and a misuse of funds.
Ballot Qualification Announced
The measure officially qualifies for the November 2026 ballot.
Valuation Date
Billionaires' net worth assessed on this date for the one-time 5% tax.
Federal Uniformity Mandate
In response to California's disparate tax rates, federal regulators require all states to impose uniform provider taxes if they seek federal Medicaid matching funds.
Proposition 35 Passes
Voters approve the ballot measure with 68% of the vote, making the MCO tax permanent and requiring revenues to fund Medi-Cal, healthcare workforce, and drug subsidies.
MCO Tax First Enacted
California introduces the Managed Care Organization tax on health insurance plans, initially with lower rates for private plans and higher for Medi-Cal.
A November ballot measure imposing a one-time 5% net-worth tax on California billionaires sets up a high-stakes legal battle over state and federal constitutional limits. Domicile definitions, uniformity clauses, and dormant Commerce Clause challenges could stall implementation even if voters approve. Legal experts are already dissecting the proposal’s vulnerabilities, with opponents preparing litigation strategies.
California's MCO tax, under Proposition 35 passed with 68% voter approval, faces federal pressure to comply with uniformity rules. Assembly Republicans' letter to HHS signals a potential legal confrontation over Medicaid reimbursement and state taxing authority.
