How to Enroll in Covered California: Open Enrollment, Deadlines, and What to Do If You Miss the Window
When does Covered California open enrollment start and end?
Covered California's open enrollment period typically runs from Nov. 1 through Jan. 31 each year, covering plans for the following coverage year. Plans selected by mid-December generally take effect Jan. 1; those selected in the second half of the window usually start Feb. 1. Confirm exact current dates at coveredca.com, as they can vary slightly by cycle.
What happens if I miss Covered California open enrollment?
If you miss Covered California's open enrollment window, you can still enroll during a special enrollment period if you experience a qualifying life event, such as losing job-based coverage, getting married, or moving to California. You generally have 60 days from the event. If you have no qualifying event and no Medi-Cal eligibility, you may face California's state tax penalty for lacking coverage.
What is California's health insurance penalty for not having coverage?
California requires most residents to have qualifying health insurance or pay a penalty assessed by the Franchise Tax Board when filing state taxes. The penalty is based on a percentage of household income or a flat per-person dollar amount, whichever is higher. Hardship exemptions are available. Use the penalty estimator at ftb.ca.gov for current figures, as the amounts are adjusted periodically.
Do I qualify for Medi-Cal or Covered California?
Which program applies depends primarily on your household income. Californians with income roughly at or below 138% of the federal poverty level generally qualify for Medi-Cal, which has no enrollment deadline and accepts applications year-round. Those with higher incomes may qualify for Covered California plans with federal premium tax credits. Applying at coveredca.com routes you to the right program automatically.
Can I get free help enrolling in Covered California?
Yes. Covered California has a statewide network of certified insurance agents and community navigators who provide free enrollment assistance. They can help you compare plans, estimate your subsidy, and complete your application at no charge. To find certified help near you, use the "Find Help" search tool on the Covered California website at coveredca.com.
Open enrollment for Covered California, the state's health insurance marketplace, runs every fall. For millions of Californians who buy their own coverage rather than getting it through an employer or a public program, this is the one window each year when they can pick or switch plans without needing a qualifying life event. Missing it has real consequences, though California's rules do offer more flexibility than the federal baseline.

When Open Enrollment Runs and What It Covers
Covered California typically holds open enrollment from Nov. 1 through Jan. 31 of the following year, though the exact dates can shift slightly from cycle to cycle. For the current enrollment period affecting 2027 coverage, check coveredca.com for the confirmed open and close dates. Plans selected during open enrollment generally take effect Jan. 1 if you enroll by a mid-December deadline, or Feb. 1 if you enroll in the second half of the window. Covered California's own enrollment calendar specifies those cutoffs each year, so don't rely on prior-year dates.
The plans sold through Covered California are private health insurance policies from participating insurers, organized into four metal tiers: Bronze, Silver, Gold, and Platinum. A fifth category, catastrophic plans, is available only to people under 30 or those who qualify for a hardship exemption. The tiers reflect how costs are split between premiums and out-of-pocket expenses at the point of care, not the quality of the coverage itself.
Financial Help: Premium Tax Credits and Cost-Sharing Reductions
The main reason to enroll through Covered California rather than buying a plan directly from an insurer is eligibility for federal premium tax credits, which can substantially reduce monthly premiums. As of 2026, those credits are available to households with incomes from 100% to 400% of the federal poverty level, and enhanced subsidies from federal legislation in recent years extended meaningful help further up the income scale. Whether those enhancements remain in place for 2027 coverage depends on federal action, and Covered California's site will reflect what's actually available once the current enrollment period is confirmed open.
Cost-sharing reductions, which lower deductibles and co-pays, are available only on Silver-tier plans and only for households with incomes generally below 250% of the federal poverty level. If you qualify for cost-sharing reductions, a Silver plan will often give you better value than a higher metal tier, even if the premiums look similar.
Medi-Cal vs. Covered California: Which One Applies to You
Covered California and Medi-Cal are separate programs that serve different income ranges, though the same application portal feeds into both. When you apply at coveredca.com, the system will route you to Medi-Cal if your household income falls below the relevant threshold, currently around 138% of the federal poverty level for most adults under 65. Medi-Cal has no open enrollment window, which is one of its key practical advantages: eligible Californians can apply and enroll any month of the year, and coverage typically starts the first of the month following approval, or sometimes the same month. If your income fluctuates, it's worth understanding that a drop in income mid-year could make you newly eligible for Medi-Cal even outside open enrollment.
California's Individual Mandate and What It Costs to Skip Coverage
California reinstated its own individual health insurance mandate starting in 2020, after the federal penalty was zeroed out. That means California residents who go without qualifying health coverage for more than three months in a calendar year can face a state tax penalty assessed by the Franchise Tax Board. The penalty is calculated as a percentage of household income or a flat dollar amount per person, whichever is higher, and grows with income. As of the most recent FTB guidance, the penalty for an adult without coverage for a full year can be several hundred dollars or more depending on income, with the FTB's own penalty estimator at ftb.ca.gov giving the current figures. Exemptions exist for hardship, short coverage gaps, and certain other situations, and you claim them when filing your California state return.

If You Miss Open Enrollment
Missing the Jan. 31 deadline does not automatically mean you're uninsured for the rest of the year. Covered California offers special enrollment periods for qualifying life events: losing job-based coverage, getting married, having a child, moving to California from another state, and others. You generally have 60 days from the triggering event to enroll. Income changes that make you newly eligible for Medi-Cal, as noted above, allow enrollment year-round regardless of that window.
If none of those apply, your options outside of enrollment windows are limited to short-term health plans, which do not meet California's qualified coverage standards and do not protect you from the state penalty, or going uninsured and paying the penalty at tax time. Neither is a particularly good option, which is the whole point of the enrollment deadline structure.
How to Actually Apply
The application is at coveredca.com and takes roughly 20 to 30 minutes if you have basic household income information in front of you. You'll need Social Security numbers or immigration documents for household members, an estimate of your 2027 household income, and information about any employer-sponsored coverage offered to you, since an affordable offer of employer coverage can affect your subsidy eligibility. Covered California also runs a certified enroller program, and free, in-person enrollment help is available in most counties through navigators and certified insurance agents, all listed on the Covered California website. There's no fee for using a navigator or a certified agent through the marketplace program.
This is general information, not legal or financial advice. Enrollment dates, income thresholds, subsidy amounts, and penalty calculations change from year to year. Always verify current open enrollment deadlines, plan options, and eligibility rules directly with Covered California at coveredca.com, and confirm any state tax penalty details with the California Franchise Tax Board at ftb.ca.gov.
