What Happens If I Over Contribute to HSA? - Avoiding Penalties and Understanding Repercussions

When it comes to your Health Savings Account (HSA), contributing too much can lead to potential issues. If you over contribute to your HSA, you may face penalties and taxes that can impact your finances.

Here's what happens if you contribute more than the allowed limit to your HSA:

  • Penalties: The IRS imposes a 6% excise tax on excess HSA contributions. This tax applies each year until the excess amount is withdrawn.
  • Taxes: Any earnings on the excess contributions are also subject to income tax. This can further reduce the benefits of your HSA.
  • Corrective Action: To avoid penalties, you must withdraw the excess contributions before the tax filing deadline for the year. You can contact your HSA provider for assistance in this process.

It's essential to stay informed about your HSA contribution limits to prevent accidental over-contributions. Monitoring your contributions throughout the year can help you avoid any potential issues.


Over contributing to your Health Savings Account (HSA) is something you want to avoid, as it can disrupt your financial plan. If you accidentally contribute beyond the allowed limit, you need to be aware of the potential penalties that can ensue.

Specifically, the IRS charges a 6% excise tax on any excess contributions, which can eat into your overall savings. This tax isn't a one-time issue; you'll be liable for it annually until you withdraw the excess funds. Additionally, interest or other earnings accrued on those excessive contributions are taxed as regular income, reducing the financial advantages of your HSA.

To prevent these penalties, ensure to withdraw any excess contributions well before your tax filing deadline. If unsure about the process, reaching out to your HSA provider can clarify the necessary steps to correct this mistake.
