What Happens If You Contribute Too Much to HSA? - Understanding the Consequences

Have you ever wondered what happens if you contribute too much to your HSA account? It's important to understand the consequences of overcontributing to avoid potential penalties and ensure you make the most of your healthcare savings. Here's what you need to know:

When you contribute more than the annual contribution limit set by the IRS to your HSA, you may face certain repercussions. Let's dive into the effects of overcontributing to your HSA:

  • Excess Contribution Penalty: The IRS imposes a 6% excise tax on excess contributions to your HSA. This penalty applies annually for the duration of the excess amount in your account.
  • Correcting Excess Contributions: To rectify overcontributions, you must withdraw the excess amount from your HSA by the tax filing deadline, including extensions. The withdrawn excess amount is not subject to the excise tax penalty.
  • Reporting Excess Contributions: You are required to report excess HSA contributions on your tax return using Form 5329. Failure to address excess contributions may result in additional IRS penalties.

It's crucial to monitor your HSA contributions throughout the year to avoid exceeding the annual limits. Consult with a financial advisor or tax professional for guidance on managing your HSA contributions and staying compliant with IRS regulations.


Overcontributing to your HSA can lead to financial repercussions that you might not expect. If you go over the contribution limits set by the IRS, not only will you face a hefty 6% excise tax on the excess amount, but you'll also need to take action quickly to correct the situation.
