Open Enrollment Dates for 2027 Coverage
Open Enrollment is the yearly window to enroll in or change an ACA plan. Here is how the federal window works, why some states differ, and your options in the meantime.
Key takeaways
- Federal Open Enrollment runs roughly Nov 1 to mid-January; mid-December for a Jan 1 start.
- State-based marketplaces can set different, sometimes later, deadlines.
- Outside the window you need a Special Enrollment Period, or a private/short-term bridge.
The federal Open Enrollment window
For states using HealthCare.gov, Open Enrollment for the coming plan year generally runs from November 1 into mid-January, with an earlier deadline (around mid-December) to have coverage start on January 1. Enrolling later in the window typically means a February 1 start.
Confirm the exact current dates on HealthCare.gov or with a licensed agent, since the window can shift year to year.
State-based marketplaces can differ
The 20-plus states that run their own marketplace (for example Covered California, Pennie, NY State of Health) can set different start and end dates, and some extend later than the federal window. If you live in one of those states, check your state marketplace directly. Our state pages link to each one.
If you need coverage outside the window
Miss Open Enrollment and you generally wait until the next one, unless a qualifying life event opens a Special Enrollment Period. Depending on your state, a private plan or a short-term plan may bridge the gap in the meantime. A licensed agent will tell you the fastest legitimate path.
