Understanding Tax Penalties for Having an HSA and Medicare Under Age 65

Having a Health Savings Account (HSA) can provide numerous benefits for managing healthcare expenses. However, if you have both an HSA and Medicare while under the age of 65, there are specific tax penalties to be aware of.

When it comes to HSA and Medicare under the age of 65, there are two key tax penalties:

  • If you use funds from your HSA for non-qualified medical expenses while also enrolled in Medicare, the withdrawal will be subject to income tax plus an additional 20% penalty.
  • If you continue to contribute to your HSA while enrolled in Medicare, those contributions may be subject to tax penalties as well.

It's crucial to understand these tax implications to avoid any unexpected financial consequences. To navigate this situation effectively, consider consulting with a tax advisor or financial planner who specializes in healthcare accounts.


When considering the benefits of a Health Savings Account (HSA), it's important to understand the potential pitfalls that arise when you are both enrolled in Medicare and under the age of 65. Notably, using HSA funds for non-qualified medical expenses can lead to serious tax implications.
