If you miss a deadline for applying for health insurance, you could be left without coverage for the entire year ahead, unless you qualify for a Special Enrollment Period.
Make sure to check your state's key deadlines below. Most states require you to enroll by December 15 if you need coverage starting January 1, 2024.
Once you enroll in health insurance, make sure to pay your first month's premium before the day your coverage begins, otherwise your insurance may not become active.
