Health insurance Open Enrollment 2026: dates, deadlines & what changed
Open Enrollment is the once-a-year window when almost anyone can buy or change an ACA marketplace plan without a qualifying life event. Here are the 2026 dates, the state exceptions, what's different this year, and how to keep coverage from lapsing on January 1.
Federal dates for 2026 coverage
For states that use HealthCare.gov, Open Enrollment for 2026 coverage runs November 1, 2025 – January 15, 2026. Enroll or make changes by December 15, 2025 for coverage that starts January 1, 2026. Enroll between December 16 and January 15 and coverage begins February 1, 2026.
State-based marketplaces (SBM) run their own windows
About 20 states operate their own exchange and sometimes extend the deadline. Always confirm on your state's marketplace, but common 2026 windows include:
- California (Covered California) — Nov 1, 2025 – Jan 31, 2026
- New York (NY State of Health) — Nov 1, 2025 – Jan 31, 2026
- New Jersey (Get Covered NJ) — Nov 1, 2025 – Jan 31, 2026
- Massachusetts (Health Connector) — Nov 1, 2025 – Jan 23, 2026
- Washington (WA Healthplanfinder) — Nov 1, 2025 – Jan 15, 2026
- Colorado, Pennsylvania, Rhode Island, DC, Minnesota, Nevada, Vermont, Kentucky, Maine, Maryland, Idaho, Georgia, Virginia, New Mexico — dates vary; check your state marketplace.
Every other state uses HealthCare.gov and follows the federal Nov 1 – Jan 15 window.
What changed for 2026
Three things to know before you shop:
- Enhanced premium tax credits. The expanded subsidies from the Inflation Reduction Act still apply, so many households earning above 400% of the federal poverty level continue to qualify for help. Your subsidy is now recalculated with 2026 benchmark plan prices — don't assume last year's number.
- Auto-renewal isn't a decision. If you take no action, most marketplaces will move you into a plan that's often not the best value for 2026. Networks, formularies, and premiums change every year.
- Doctor networks are moving. Several large carriers restructured PPO and HMO networks for 2026. Even if your plan name looks the same, verify your doctors and prescriptions before renewing.
Missed it? Special Enrollment Periods
Outside Open Enrollment you generally need a qualifying life event to enroll:
- Loss of other coverage (job loss, aging off a parent's plan, COBRA ending)
- Marriage, divorce, birth or adoption of a child
- Permanent move to a new coverage area
- Household income change that makes you newly eligible for subsidies
Most SEPs give you a 60-day window. If you don't qualify for an SEP, private off-exchange plans, short-term policies, and health-sharing options are still available year-round — with important trade-offs.
How to enroll without a coverage gap
- Enroll by Dec 15, 2025 for Jan 1 coverage.
- Verify income on your application. Underestimating loses subsidy at tax time; overestimating means you overpay all year.
- Check every doctor and medication against the plan's 2026 network and drug list — carriers renew every January.
- Pay the first premium before the effective date. Even an approved plan doesn't activate until the first payment is received.
- Save your enrollment confirmation and Summary of Benefits (SBC) — you'll need them if a claim is denied.
Frequently asked questions
Can I change plans after Open Enrollment ends?
Only with a qualifying life event or if you're eligible for Medicaid/CHIP (year-round enrollment).
Do I have to reapply if I have coverage now?
You don't have to, but you should. Updating income, household, and plan choice each year usually saves money.
Is there a penalty for being uninsured in 2026?
There's no federal penalty, but a handful of states (California, DC, Massachusetts, New Jersey, Rhode Island, Vermont) have their own mandate.
What if I already have a job-based plan?
You can still shop the marketplace, but you generally won't qualify for a subsidy unless your employer coverage is unaffordable or doesn't meet minimum value.
