Everything California residents need to enroll in 2026 ACA / Obamacare coverage — your marketplace, the dates, and how to get free help.
California runs Covered California, its own state-based health insurance marketplace. That means you enroll, compare plans, and manage your coverage through California's own website rather than the federal site — and your state may set its own special enrollment rules and deadlines.
For 2026 coverage, open enrollment is November 1 – January 15 for most steps, with this state's own marketplace extending the final deadline into late January (around January 23–31 — confirm the exact date on your state's site). Miss it and you generally need a qualifying life event (a move, job loss, marriage, or new baby) to enroll outside the window.
Almost anyone in California who isn't on Medicare can buy a marketplace plan. Premium tax credits lower your monthly cost based on income and household size — many enrollees qualify for substantial savings, and the marketplace calculates it for you when you apply.
You don't have to figure this out alone, and help costs you nothing. A licensed health insurance agent compares California plans, checks that your doctors and medications are covered, and enrolls you — paid by the carrier, not you. (See how agent help works on our ACA guide.)
