How to Know if HSA is Pre Tax or Post Tax W2?

Health Savings Accounts (HSAs) have gained popularity as a tax-advantaged way to save for medical expenses. When it comes to determining if your HSA contributions are pre-tax or post-tax on your W-2 form, there are a few key things to consider.

To know if your HSA contributions are pre-tax or post-tax on your W-2, you need to look at the following factors:

  • Employer Contributions: If your employer contributes to your HSA, those contributions are typically considered pre-tax and will not be included in your taxable income on your W-2.
  • Employee Contributions: If you make contributions to your HSA using pre-tax dollars through a payroll deduction, those contributions are also considered pre-tax and will not be included in your taxable income on your W-2.
  • If you make contributions to your HSA using after-tax dollars and then deduct them on your tax return, those contributions are considered post-tax and will be included in your taxable income on your W-2.

By understanding these factors and how your HSA contributions are treated for tax purposes, you can determine if they are pre-tax or post-tax on your W-2 form.


Health Savings Accounts (HSAs) are an excellent way for individuals to save for out-of-pocket medical expenses with tax benefits. To determine if your contributions are pre-tax or post-tax on your W-2 form, you should first examine how contributions are being made.

To clarify your HSA contributions on your W-2, consider these aspects:

  • Employer Contributions: If your employer contributes to your HSA, those amounts are generally treated as pre-tax. This means they won’t show up in your taxable income on your W-2.
  • Employee Contributions: If you opt for payroll deductions to contribute to your HSA, your contributions are pre-tax and excluded from your W-2 taxable income.
  • After-Tax Contributions: If you're contributing to your HSA with after-tax dollars and then claiming a deduction for them, these amounts will be recorded as post-tax income on your W-2.

Understanding these points can help you easily identify whether your HSA contributions are pre-tax or post-tax on your tax forms.
