Which W2 Box is HSA Contribution? Everything You Need to Know

When it comes to understanding your W2 form and figuring out where your HSA contribution is listed, it's essential to know which box to look for. Your HSA contributions are typically reported in box 12 of your W2 form with a specific code to identify them. This makes it easy for you to locate and track your contributions accurately.

Here's a breakdown of how HSA contributions are reported on your W2 form:

  • Box 12: Your HSA contributions are generally listed in box 12 with the code 'W'.
  • Box 3 and Box 5: Your HSA contributions are not included in boxes 3 (Social Security wages) and 5 (Medicare wages) of your W2 form as they are pre-tax contributions.

Understanding where your HSA contributions are listed on your W2 form is crucial for accurately reporting them on your tax return and maximizing the tax benefits associated with your HSA.


Finding your HSA contributions on your W2 form is crucial for ensuring that your tax filings are correct, and they are typically located in box 12 alongside code 'W'. This specific labeling aids in your tax return preparations.
