How is HSA Reported on W2? - A Comprehensive Guide

When it comes to Health Savings Accounts (HSAs), many individuals wonder how they are reported on their W-2 forms. Understanding the implications of HSA contributions on your W-2 can help you better navigate tax season and ensure compliance with IRS regulations.

It's important to note that HSA contributions are reported on your W-2 in Box 12 using the code W. This amount includes both your contributions and any employer contributions made to your HSA account during the tax year.

Unlike Flexible Spending Accounts (FSAs), contributions to your HSA are not subject to federal income tax withholding. This means that the contributions you make to your HSA are tax-deductible, reducing your taxable income for the year.

Here are some key points to keep in mind when it comes to how HSAs are reported on your W-2:

  • HSA contributions are reported in Box 12 with the code W
  • Both employee and employer contributions are included in this amount
  • Contributions to HSAs are tax-deductible
  • HSAs offer triple tax benefits: tax-deductible contributions, tax-deferred growth, and tax-free withdrawals for qualified medical expenses

By understanding how HSAs are reported on your W-2, you can make informed decisions about your healthcare savings and maximize the tax benefits of these accounts.


Understanding how Health Savings Accounts (HSAs) are represented on your W-2 form is crucial for effective tax planning. The contributions made to your HSA are reported in Box 12 with the letter W, encompassing contributions from both you and your employer.
