ACA Open Enrollment Deadlines You Shouldn't Miss

Open Enrollment is the main window to sign up for Marketplace coverage. Here's when it happens and what to do if you miss it.

5 min readReviewed for the 2026 plan year

Annual Open Enrollment Window

Most states follow a November 1 – January 15 Open Enrollment Period for Marketplace coverage, though some state-based exchanges set their own dates — always confirm your state's specific deadlines.

What Happens If You Miss It

Outside Open Enrollment, you generally need a qualifying life event — like losing job-based coverage, having a baby, or moving — to trigger a Special Enrollment Period.

Coverage Start Dates

Enrolling earlier in the window typically means coverage starts January 1; enrolling later in the window often pushes your start date to February 1.

Key Takeaways

  • Open Enrollment dates vary slightly by state — confirm your exchange's exact deadline.
  • Missing Open Enrollment generally requires a qualifying life event for a Special Enrollment Period.
  • Enrollment timing affects your coverage start date.

Enrollment dates vary by state-based exchange. Confirm exact deadlines at Healthcare.gov or your state Marketplace.
