How old do you have to be to get Medicare?

Your full retirement age is the age at which you can receive full retirement benefits from Social Security. However, it is not necessarily the age at which you qualify for Medicare. 

Regardless of which year you were born, you will become eligible for Medicare at age 65 (unless you’re eligible earlier because you have a qualifying disability).

If you begin collecting Social Security retirement benefits prior to turning 65 years old, you will be automatically enrolled in Medicare around your 65th birthday. If you are not yet collecting Social Security by that age, you will have to sign up for Medicare. 

Depending on your circumstances, you may qualify for a Special Enrollment Period that will allow you to sign up for Medicare outside of the normal enrollment periods and protect you from late enrollment fees. Losing employer-based health insurance coverage because you retired from your job is one of the life events that can qualify you for a Special Enrollment Period.
