Are HSA Contributions Deducted from Box 1 of W2 Forms? - HSA Awareness

If you contribute regularly to your Health Savings Account (HSA), you may wonder whether those contributions are deducted from Box 1 of your W2 forms. The answer is that HSA contributions are not included in Box 1 of your W2 form as they are not subject to federal income tax.

When you make contributions to your HSA, your contributions are made on a pre-tax basis, meaning they are deducted from your gross income before taxes are calculated. This results in a lower taxable income for you, providing tax savings.

Here's a breakdown of how HSA contributions are treated:

  • HSA contributions are not included in Box 1 of your W2 form
  • Contributions are deducted from your gross income before taxes
  • HSA contributions reduce your taxable income, leading to tax savings
  • Employer contributions to your HSA are also excluded from Box 1 of your W2 form

It's important to note that the contributions you make to your HSA may be listed separately on your W2 form for informational purposes, but they do not impact the amount reported in Box 1.


When contributing to a Health Savings Account (HSA), it’s crucial to understand a few key points about how these contributions appear on your W2 forms. Notably, HSA contributions are excluded from Box 1 of your W2 because they are pre-tax contributions.
