During the annual Open Enrollment Period, almost all Americans can enroll in health insurance through the Federal Marketplace.
The Open Enrollment Period for most states is November 1st – December 15th. If you enroll by December 15th, your coverage will begin January 1st.
Outside of the Open Enrollment Period, you can only enroll if you have a Qualifying Life Event, such as losing your health insurance, adopting a baby, or getting married.
