What if I Forgot to Include Employer Contributions to HSA on Taxes?

Forgetting to include employer contributions to your HSA on your taxes can lead to potential complications, but it is a common mistake that can be rectified. Employer contributions to your Health Savings Account (HSA) are considered non-taxable income, meaning they are not subject to federal income tax, and in most cases, not subject to state income tax as well.

If you have forgotten to include these contributions on your taxes, here's what you can do:

  • Correct the Mistake: Amend your tax return as soon as possible if you have already filed without including the employer contributions to your HSA.
  • File an Amended Return: Use IRS Form 1040X to file an amended return. Make sure to include the correct information about your employer contributions to avoid any penalties or repercussions.
  • Seek Professional Help: If you are unsure about how to proceed or if you need assistance in amending your tax return, consider consulting a tax professional or accountant.
  • Understand the Rules: Educate yourself about HSA rules and regulations to prevent similar errors in the future.

Remember, it is essential to be proactive in correcting any mistakes on your tax return, including forgetting to include employer contributions to your HSA. By taking the necessary steps to rectify this error, you can avoid any potential issues with the IRS and ensure compliance with tax laws.


It’s easy to overlook employer contributions to your HSA when filing taxes, but doing so can be problematic. It’s a common error that many taxpayers make. Thankfully, you can still address it after filing your return.
