Medicare and Your HSA: When to Stop Contributing
If maximizing HSA contributions is a priority, you may want to delay all parts of Medicare — including Part A. Enrolling in any part of Medicare ends your HSA contribution eligibility. Part A can be retroactive up to 6 months, so stop contributing 6 months before you plan to enroll.
When This Applies
- You have an HSA and are approaching 65
- You contribute to an HSA through a high-deductible plan
- You are working past 65 and want to keep your HSA
- Your employer contributes to your HSA
Frequently Asked Questions
- Can I spend existing HSA funds after Medicare?
- Yes. You can use HSA money tax-free for qualified medical expenses, including Medicare premiums (except Medigap), even after enrolling.
- What if I already contributed too much?
- You can withdraw excess contributions before your tax filing deadline to avoid the 6% IRS excise tax.
- Should I delay Social Security too?
- If HSA contributions are important, consider delaying Social Security, since starting SS triggers automatic Part A enrollment.
