- November 1, 2025: Open enrollment begins.
- December 15, 2025: Last day to enroll or change plans for coverage starting January 1, 2026.

Some states with their own exchanges may have slightly different deadlines. Also, employer-sponsored health insurance open enrollment dates may vary and are set by employers.
