Understanding How HSA Excess Contributions are Reported to Account Holders

Health Savings Accounts (HSAs) are a valuable tool for managing healthcare expenses, allowing individuals to save money tax-free for medical costs. However, it's important for account holders to be aware of how excess contributions to an HSA are handled and reported.

Excess contributions occur when an individual contributes more than the allowable limit set by the IRS for that tax year. It's crucial to stay within these limits to avoid penalties and comply with the tax regulations.

If you have made excess contributions to your HSA, here's how it will be reported to you:

  • The HSA administrator is required to notify you of the excess contribution through a written notice.
  • You will need to withdraw the excess contributions and any earnings on those contributions by the tax filing deadline to avoid penalties.
  • The withdrawn excess contributions are not included in your taxable income for that year but must be reported on your tax return.
  • Form 1099-SA will be issued by the HSA administrator to report the distribution of excess contributions.
  • You must file Form 5329 with your tax return to report the excess contribution and pay the 6% excise tax on the excess amount.

It's crucial to be proactive in correcting excess contributions to your HSA to avoid potential penalties and ensure compliance with IRS regulations. Consult with a tax advisor or HSA administrator for guidance on the necessary steps to take if you have made excess contributions.


Health Savings Accounts (HSAs) offer a unique opportunity to save for medical expenses in a tax-advantaged way, but account holders must remain vigilant about the contribution limits.

When you contribute to your HSA, it is essential to keep the IRS contribution limits in mind, as exceeding these limits can lead to excess contributions.

Failing to address excess contributions can result in penalties, making it important to know how these are reported and what steps to take.

  • You’ll receive a written notice from your HSA administrator if you've contributed too much.
  • If you find yourself in this situation, withdraw the excess amounts, along with any earnings, prior to the tax filing deadline to avoid penalties.
  • The amount you've withdrawn will not count as taxable income for that year, but you still need to disclose it on your tax return.
  • Your HSA administrator will issue Form 1099-SA, summarizing the distribution of these excess contributions.
  • To officially report this excess contribution, you will have to file Form 5329 along with your tax return and pay a 6% excise tax on the excess amount.

It's advisable to stay informed about your HSA contributions to avoid complications, and seeking assistance from a tax advisor can be beneficial in such situations.
