When is open enrollment for health insurance 2026? That’s the most pressing question on many minds today as deadlines approach for choosing coverage. For the 2026 plan year, the national open enrollment window begins November 1, 2025, and ends January 15, 2026. Signing up by December 15, 2025, ensures coverage starting on January 1, 2026, while enrollments completed after that date but before January 15 will begin coverage on February 1, 2026.
Latest Updates and Changes for 2026
