When should I start preparing for Medicare at 65?

Start at least 3 months before your 65th birthday month — that is when your Initial Enrollment Period opens. Reviewing your situation earlier gives you time to check employer coverage, HSA timing, and drug coverage credibility.

What is the most important Medicare deadline at 65?

Enrolling in Part B during your Initial Enrollment Period (or a qualifying Special Enrollment Period) is the most important deadline. Missing it without qualifying employer coverage results in a permanent 10% per year penalty.

Do I need to do anything if I am already on Social Security?

You will likely be enrolled automatically in Parts A and B. Check for your Medicare card in the mail before your 65th birthday and confirm your coverage start date.

What happens to my HSA when I turn 65?

Enrolling in any part of Medicare — including Part A — stops your ability to contribute to an HSA. Plan to stop contributions before your Medicare start date to avoid IRS penalties on excess contributions.
