Between January 1 – March 31 each year
You can sign up for Part A and/or B during the General Enrollment Period Between Jan 1 – March 31 each year if both of these apply:
- You didn’t sign up when you were first eligible.
- You aren’t eligible for a Special Enrollment Period (see below).
- You must pay premiums for Part A and/or Part B. Your coverage will start July 1. You may have to pay a higher premium for late enrollment in Part A and/or a higher premium for late enrollment in Part B.
Once your Initial Enrollment Period ends, you may have the chance to sign up for Medicare during a Special Enrollment Period (SEP). If you’re covered under a group health plan based on current employment, you have a SEP to sign up for Part A and/or Part B anytime as long as:
- You or your spouse (or family member if you’re disabled) is working.
- You’re covered by a group health plan through the employer or union based on that work.
- You also have an 8-month SEP to sign up for Part A and/or Part B that starts at one of these times (whichever happens first):
- The month after the employment ends
- The month after group health plan insurance based on current employment ends
- Usually, you don’t pay a late enrollment penalty if you sign up during a SEP.
