What Happens When a Person Who Has an HSA Becomes Ineligible (e.g., is on Medicare)?

Health Savings Accounts (HSAs) provide individuals with a tax-advantaged way to save and pay for medical expenses. However, certain events like becoming ineligible, such as enrolling in Medicare, can impact the use of an HSA.

When a person who has an HSA becomes ineligible (e.g., is on Medicare), here's what happens:

  • Contributions: Once enrolled in Medicare, individuals can no longer contribute to their HSA as Medicare coverage disqualifies them from making further contributions.
  • Withdrawals: While individuals can still use the funds in their HSA for qualified medical expenses even after enrolling in Medicare, they cannot use the HSA funds to pay for premiums or other non-qualified expenses.
  • Tax Implications: Contributions made to an HSA while eligible are tax-deductible, but if a person becomes ineligible due to Medicare enrollment, they need to stop contributing, and there might be tax implications to consider.

It's essential to understand the implications of becoming ineligible for an HSA, such as when enrolling in Medicare, to avoid any penalties or tax issues.


As you reach significant milestones in life, such as enrolling in Medicare, it’s important to know the impact on your Health Savings Account (HSA). Enrolling in Medicare means you will have to navigate changes concerning your HSA and how you manage your healthcare expenses.
