Do I get Medicare automatically at 65?

Only if you already get Social Security or Railroad Retirement benefits. In that case you are usually enrolled in Part A and Part B automatically. Otherwise you sign up yourself through Social Security.

What if I’m still working?

You may be able to wait on Part B without a penalty if you have coverage through your own or your spouse’s current job. Ask your benefits office how your plan works with Medicare, because it depends on the employer’s size and the kind of coverage.

What happens if I miss my enrollment window?

You may owe a late penalty for Part B, Part D, or both, and you may have to wait for the next general enrollment period. The penalties last for as long as you have the coverage. Check the rules for your situation before assuming you missed it.

Most people find out about Medicare timing from a letter, a neighbor, or a birthday that is closer than they thought. This checklist walks through it in order. I wrote it for North Carolina, and I meet people in person around the Triad or by phone.

Your 7-month enrollment window

Your Initial Enrollment Period lasts 7 months. It starts 3 months before the month you turn 65, includes your birthday month, and ends 3 months after.

For example, if you turn 65 in April, your window runs January through July. If you turn 65 in August, it runs May through November.

When you sign up affects when coverage starts. If you enroll in Part B before your birthday month, coverage starts the first of your birthday month. If you enroll during or after your birthday month, it starts the next month. If your birthday is on the first of the month, coverage starts the month before.

How to sign up for Parts A and B

If you already get Social Security or Railroad Retirement benefits, you are usually enrolled in Part A and Part B automatically. If you do not, you sign up through Social Security. You can do it online, by phone, or at a local office.

If you are still working and have coverage through your employer, you may be able to wait on Part B without a penalty. Whether you can depends on the employer’s size and the kind of coverage, so ask your benefits office before you decide. If you contribute to a health savings account, ask about that too, because enrolling in Medicare affects contributions.

When job coverage ends, you get a Special Enrollment Period of up to 8 months to sign up for Part B without a penalty. That window does not apply while you are still in your Initial Enrollment Period.

The three decisions everyone faces

Original Medicare with a Medigap policy, or Medicare Advantage. Here is how they compare.
Prescription drug coverage. You need it either through a Part D plan or an Advantage plan that includes it.
Timing. When you sign up, and whether you have other coverage that lets you wait.

Late penalties, in plain English

If you go without Part B when you should have signed up, you pay an extra 10% of the standard premium for each full 12-month period you waited. The standard Part B premium is $202.90 in 2026. You keep paying that extra amount for as long as you have Part B. You can estimate yours with our penalty calculator.

If you go without Part D or other creditable drug coverage, you pay 1% of the national base premium for each full month you waited. That base premium is $38.99 in 2026. You pay it for as long as you have drug coverage. You can avoid both by signing up on time or by having coverage that counts.

A simple timeline

Three months out:

Find your Medicare enrollment window dates.
Ask your employer, if you have one, how your coverage works with Medicare.
List your doctors and your prescriptions.

One month out:

Sign up for Part A and Part B, or confirm that you are already enrolled.
Compare Advantage plans or Medigap and Part D options for your address.

After you enroll:

Check that your Medicare card arrived and your coverage start date is right.
Confirm your plan choice is in place before the first month of coverage.
Mark your calendar for October 15 to December 7, the yearly window to review your plan.

If you want to see your own dates laid out, our timeline tool builds them from your birthday.
