Where Do Employer HSA Contributions Go on W2?

Employer contributions to your Health Savings Account (HSA) are a great benefit that can help you save money for medical expenses. But when it comes to tax time, you may wonder where these contributions show up on your W2 form.

When your employer contributes to your HSA, it is considered a non-taxable fringe benefit. This means that the amount of the contribution is not included in your gross income, and therefore, it does not appear in Box 1 of your W2 form.

So, where exactly do employer HSA contributions go on your W2? Here's the breakdown:

  • Box 12: Your employer's contributions to your HSA will be reported in Box 12 with a Code W.
  • Box 14: Some employers may also choose to report HSA contributions in Box 14, where they can provide additional information or codes related to the contributions.

It's important to note that while employer contributions are not taxable, any contributions you make to your HSA with post-tax dollars will be reported on your W2 as part of your gross income.

Understanding where your employer HSA contributions appear on your W2 can help you accurately report your income and ensure compliance with tax regulations. Be sure to consult with a tax professional if you have any questions or need further clarification.


Understanding where your employer's contributions to your Health Savings Account (HSA) show up on your W2 is essential for managing your tax responsibilities effectively. Specifically, these contributions are categorized as a non-taxable fringe benefit, meaning they have the potential to save you money during tax season.
