Executive Summary
- Most states follow the federal Open Enrollment Period, running November 1, 2025 to January 15, 2026 (enroll by December 15, 2025 for coverage starting January 1, 2026).
- States with their own exchanges have different windows — for example, California runs November 1, 2025 to January 31, 2026, and New York runs November 16, 2025 to January 31, 2026.
- Outside open enrollment, individuals can still get coverage through a Special Enrollment Period (SEP) triggered by a Qualifying Life Event, such as loss of coverage, marriage/divorce, birth/adoption, a move, or an income change.
- The Special Enrollment Period lasts only 60 days from the qualifying event; missing that window means waiting until the next annual open enrollment period.
The annual Open Enrollment Period (OEP) is a designated timeframe during which individuals can enroll in or make changes to their health insurance plans. For the 2025 coverage year, the OEP dates vary by state. Below is a overview to the open enrollment deadlines for each state:

What If You Miss the Open Enrollment Deadline?
If you miss the OEP, you may still have options to obtain health insurance through a Special Enrollment Period (SEP). SEPs are triggered by qualifying life events such as:
- Loss of other health coverage
- Changes in household (e.g., marriage, divorce, birth of a child)
- Changes in residence
To determine eligibility for an SEP, visit the HealthCare.gov Special Enrollment Period.
Qualifying Life Event
A Qualifying Life Event (QLE) is something you experience that results in a life situation change and thus makes you eligible for a Special Enrollment Period to apply for health insurance even if you’ve missed the annual open enrollment deadline. Qualifying life event includes:
- Loss of health insurance through your job, school, family
- Changes in the household such as getting married or divorced, having a baby or adopting a child, death of a family member
- Change of home address
- Your employer offers to help with the cost of coverage
- Other qualifying events
- Changes in your income
- Gaining membership in a federally recognized tribe or status as an Alaska Native Claims Settlement Act (ANCSA) Corporation shareholder
- Becoming a U.S. citizen
- Leaving jail or prison
- AmeriCorps members starting or ending their service
How Long is the Special Enrollment Period (SEP)?
If you are qualified for a special enrollment period, you’ll have 60 days to enroll in a plan. If you miss that 60-day window, you’ll have to wait until the open enrollment period of that year.

Frequently Asked Questions (FAQs)
Q: How does open enrollment work for my employees?
Employees receive a notification when open enrollment opens, then log into the self-service portal to review plan options with cost comparisons and make their selections. Elections flow directly into payroll deductions automatically.
Q: What happens if my business or an employee misses the open enrollment deadline?
Missing the deadline doesn't necessarily mean waiting until next year — a Special Enrollment Period (SEP) may be available if the employee experiences a qualifying life event, such as losing other coverage, a change in household, or a change in residence. Once eligible, they'll have 60 days to enroll in a plan.
Q: What counts as a "qualifying life event" for a special enrollment period?
Common qualifying life events include losing health coverage through a job, school, or family member; getting married or divorced; having or adopting a child; a change of home address; changes in income; or becoming a U.S. citizen, among others. It's best to confirm specific eligibility through HealthCare.gov or your state's exchange.
