What Happens if You Over Contribute to an HSA?

Having a Health Savings Account (HSA) is a great way to save for medical expenses while enjoying tax benefits. However, it's essential to be mindful of the contribution limits set by the IRS to avoid any penalties or complications.

If you end up contributing more than the allowed limit to your HSA, the excess amount is considered an 'over-contribution.' Here's what happens if you over contribute to an HSA:

  1. Tax implications: The excess contribution amount is subject to a 6% excise tax imposed by the IRS.
  2. Penalties: You may face penalties for over-contributing, including IRS penalties and potential tax implications on the excess amount.
  3. Corrective action: To rectify the situation, you can withdraw the excess contributions before the tax filing deadline for the year. This withdrawal should include any earnings generated by the excess amount as well.
  4. Reporting requirements: It's crucial to report the excess contributions and any corrective actions taken on your tax return to avoid further penalties or audits.

It's important to stay informed about HSA contribution limits and monitor your contributions throughout the year to prevent over-contributions. Consulting a financial advisor or tax professional can help you navigate any potential issues related to over-contributions to your HSA.


Over-contributing to your Health Savings Account (HSA) can lead to unexpected financial headaches, making it crucial to keep track of your contributions. Remember, any excess contribution is subjected to a steep 6% excise tax mandated by the IRS, which can add up quickly.
