California’s state health coverage program covers ~14.5M residents, >one-third of the population, and represents $222B in annual spending for 2026-2027 in the governor’s budget.
Federal funding shapes California’s incentives: expanded-coverage enrollees receive ~90% federal support, while traditional populations receive ~50%, shifting major costs onto federal taxpayers overall.
Provider tax arrangements also boost matching funds: California pays providers more, collects taxes on higher amounts, then offsets added state spending commitments.
A 2025 federal law added work requirements, more frequent eligibility checks, and tighter limits on provider tax strategies affecting California’s expanded coverage.
State analysts and independent forecasts point to ongoing budget pressure, including an $8B shortfall, as California weighs revenue or eligibility changes ahead.
