Where to Deduct HSA on 1040 2 Percent S Corporation Owner

When it comes to deducting your HSA contributions as a 2 percent S Corporation owner on your 1040 form, there are specific steps you need to follow.

First and foremost, as a 2 percent shareholder of an S Corporation, you are considered to be an employee of the company. This means that any HSA contributions made on your behalf by the S Corporation should be treated as employer contributions.

When filling out your 1040 form, here's where you should deduct your HSA contributions:

  • Report the total amount of HSA contributions made by the S Corporation in Box 12 of your W-2 form with Code W.
  • Next, you should deduct these contributions on Form 1040 as an adjustment to income on Line 25. This allows you to exclude these contributions from your gross income, ultimately lowering your taxable income.

By following these steps, you can ensure that you are accurately deducting your HSA contributions as a 2 percent S Corporation owner on your 1040 form.


As a 2 percent shareholder in an S Corporation, understanding how to deduct HSA contributions on your 1040 form is essential for maximizing your tax benefits. Make sure to verify that the total HSA contributions are correctly reported in Box 12 of your W-2 form using Code W.
