There Are Two Different Deadlines for ACA Coverage. Know Both.
ACA Marketplace Open Enrollment runs November 1 through January 15, 2027. But there are actually two deadlines that matter -- and they lead to two different coverage start dates.
Enroll by December 15: coverage starts January 1, 2027. Enroll December 16 through January 15: coverage starts February 1, 2027.
That gap matters. If you are losing other coverage on December 31 -- job-based insurance, COBRA, a spouse's plan -- you need your new coverage in place on January 1, not February 1. That means completing your enrollment by December 15.
Most people assume they have until January 15 for January 1 coverage. They do not.
If January 1 is your target start date, plan to complete enrollment in November and give yourself enough time to compare options carefully. Rushing to meet December 15 is better than missing it entirely.
