How Medicare Enrollment Works

Your Initial Enrollment Period (IEP) is a 7-month window centered on the month you turn 65. Missing this window can result in permanent late enrollment penalties that increase your premiums for life. Enter your birthday below to see your exact enrollment dates.

Birth Year

I was born on the 1st of the month

Medicare considers you turning 65 one month earlier if born on the 1st

💼 Employment Coverage

If you have health insurance through your employer (or your spouse's employer), you may be able to delay Medicare Part B without a penalty.

No employer coverage at 65

I will NOT have employer health insurance when I turn 65
