What Box 12 Do I Put On for HSA? - Understanding HSA Contributions

When it comes to Health Savings Accounts (HSAs), understanding where to report contributions on your tax forms is essential. One of the common questions that arise is, 'What Box 12 do I put on for HSA?'

When you contribute to an HSA, the amount is reported on your W-2 form in Box 12 with the code 'W'.

It's important to correctly report your HSA contributions to ensure you receive any tax benefits you are eligible for. Here are some key points to remember:

  • Box 12 with the code 'W' on your W-2 form is where you report your HSA contributions.
  • Employer contributions made through a cafeteria plan are not included in Box 12. They are already excluded from your gross income.
  • If you made contributions outside of your employer, they are reported on Form 8889 when filing your taxes.

Understanding how to report HSA contributions ensures that you comply with tax regulations and maximize the benefits of your HSA. If you have any doubts, consult a tax professional for guidance.


When dealing with Health Savings Accounts (HSAs), it’s crucial to understand how your contributions impact your taxes. If you’re asking, 'What Box 12 do I put on for HSA?', the answer lies in Box 12, specifically coded 'W', which signifies your HSA contributions on your W-2 form.
