When Can You Enroll in Medicare?

Medicare has specific windows for when you can sign up. Missing the right time could mean delays or penalties — so it’s important to know when you can enroll.

Let’s break it down:


Initial Enrollment Period (IEP)

This is your first chance to sign up for Medicare.

When?
It’s a 7-month window:

  • Starts 3 months before the month you turn 65
  • Includes your birthday month
  • Ends 3 months after your birthday month

📝 Example:
If your birthday is in July, your enrollment window is April 1 to October 31.


Special Enrollment Period (SEP)

Still working at 65 and have employer health insurance?
You may be able to delay Medicare without a penalty.

You’ll get a Special Enrollment Period when:

  • You (or your spouse) stop working
  • Or you lose employer coverage

You have 8 months to enroll in Part B after that coverage ends.


General Enrollment Period (GEP)

Missed your IEP and don’t qualify for a SEP?

You can sign up between:

📅 January 1 – March 31
Coverage starts July 1
⚠️ You might pay a late enrollment penalty


Annual Enrollment Period (AEP)

Already on Medicare and want to switch plans?

📅 October 15 – December 7 every year
You can:

  • Switch from Original Medicare to a Medicare Advantage plan
  • Change your Part D prescription drug plan
  • Switch from one Advantage plan to another

Medicare Advantage Open Enrollment

If you’re already in a Medicare Advantage plan, you get another chance to make changes.

📅 January 1 – March 31

You can:

  • Switch to another Advantage plan
  • Drop Advantage and go back to Original Medicare
