Initial Enrollment Period (IEP) Calculator

Your Initial Enrollment Period (IEP) is your first chance to sign up for Medicare. Enter your date of birth below to see when your IEP starts, when your Medicare coverage begins, and the last day to enroll without late penalties.

If you are using the Medicare Explainer Workbook, write these dates in the “My Initial Enrollment Period (IEP)” section so you have them handy when we talk.
