The most recent Open Enrollment period was November 1, 2024 through January 23, 2025. The next begins November 1, 2025.

In general, Open Enrollment is the only time of year when you can purchase or change insurance plans for any reason. However, you may be allowed to enroll any time of year if you experience certain life events, such as losing your current insurance. If you qualify for MassHealth, or for a ConnectorCare plan, or want to purchase a stand alone dental plan, you may enroll at any time during the year. Find out more now →

When you enroll in a health or dental plan by the enrollment deadline – which is the 23rd day of each month – then the earliest plan start date is the first day of the following month. For example, if you complete enrollment by September 23, then your coverage start date will be October 1.

If you are applying and enrolling in a Health Connector or ConnectorCare plan for the first time, your enrollment isn't finished until you checkout your plan and make your first premium payment for your coverage by the due date. If you miss this deadline, the earliest date your coverage could start is the first day of the following month.
