Open Enrollment is the period in the year when you can enroll in a health insurance plan through the Health Connector Marketplace without a qualifying event.
The 2027 Open Enrollment is October 23, 2026, through January 23, 2027.
Outside the Open Enrollment Period, you generally can enroll in a health insurance plan only if you qualify for a Special Enrollment Period. You qualify if you have certain life events, like getting married, having a baby, or losing other health coverage. Learn more →
You can enroll any time of the year if:
- You qualify for MassHealth.
- You now qualify for a ConnectorCare plan through the Health Connector after not having qualified in the past, or after applying for the first time.
- You are applying for dental coverage.
- You are a member of a federally recognized tribe or Alaska Native shareholder.
If you have insurance from a job, job-based plans may have different Open Enrollment Periods. Check with your employer.
