Can I keep my HSA after I enroll in Medicare?
Once Part A starts, you have to stop putting money into your HSA. If you sign up for Part A later, it can start up to six months before the day you apply.
Goes deeper on: When do I need to sign up for Medicare? (Medicare Clarity Guide)
The short version
- An HSA is a health savings account.
- The rule is about putting money in. Once Part A starts, you have to stop.
- If you sign up for Part A later, it can start up to six months earlier than the day you apply.
Why the start date matters
The rule follows the day Part A starts, not the day you apply. If you sign up for Part A later, that start day can land up to six months before you apply. So stop contributions up to six months before you apply.
What this page doesn't cover
This page covers one rule: when contributions stop. It doesn't cover the money already in your account, or your own tax situation. A tax professional can help with your own account.
The HSA catch is in step 2 of our Medicare guide, under "Going deeper".
Your next step
