California Individual Health Insurance Laws & Regulations

Buying your own health insurance in California comes with strong consumer protections. Under the Affordable Care Act, all individual and family plans sold in California are guaranteed issue — you cannot be denied coverage or charged more because of a pre-existing condition, and there are no medical-underwriting questions on ACA plans.

California’s Individual Mandate

Unlike most states, California has its own health-coverage requirement. Most residents must maintain qualifying (minimum essential) coverage each month or pay a penalty when they file their state taxes with the California Franchise Tax Board. The penalty is roughly $900+ per adult (about half that per dependent child), or 2.5% of household income above the filing threshold — whichever is greater — and the figure is adjusted for inflation each year.

Where to Buy & Financial Help

Californians shop for individual and family plans through Covered California, the state’s official marketplace, or directly with carriers. Buying through Covered California is the only way to receive premium subsidies. Most enrollees qualify for federal premium tax credits, and California also offers additional state-funded subsidies that can further lower monthly premiums — help that isn’t available in many other states.

When You Can Enroll

Open Enrollment runs each fall through the start of the year (typically November 1 – January 31). Outside that window, a qualifying life event — losing coverage, moving, marriage, or a new baby — opens a Special Enrollment Period.
