Do Employer HSA Contributions Go on W2? Everything You Need to Know

One common question that arises regarding Health Savings Accounts (HSAs) is whether employer contributions should be included on an employee's W-2 form. Let's dive into this topic to provide clarity on how employer HSA contributions are treated.

Firstly, it's essential to understand that HSA contributions come from various sources:

  • Employee contributions made through payroll deductions
  • Employer contributions to the employee's HSA
  • Contributions from any other individuals, such as family members

Now, when it comes to employer contributions specifically:

  • Employer contributions to an employee's HSA are generally considered as part of the employee's gross income.
  • However, these employer contributions are typically not subject to federal income tax, FICA tax, or state income tax.
  • Employer HSA contributions should be reported in Box 12 of the employee's W-2 form with the code W.

It's crucial for both employers and employees to understand how employer HSA contributions are treated for tax purposes. By correctly reporting these contributions, individuals can ensure compliance with IRS regulations and maximize the benefits of their HSA.


Understanding the implications of employer contributions to Health Savings Accounts (HSAs) is crucial for navigating healthcare expenses. Let's clarify whether these contributions appear on your W-2 form.

Employer contributions are part of the broader HSA funding process, which also includes:

  • Contributions made by employees directly through payroll deductions.
  • Additional contributions from third parties like family members or friends.

For employer HSA contributions:

  • These amounts are included in the gross income calculation for the employee.
  • Nevertheless, they benefit from favorable tax treatment—they are excluded from federal income tax, FICA tax, and most state income taxes.
  • Look for these contributions in Box 12 of your W-2 form, labeled with the code W for easy identification.

This knowledge helps both employees and employers keep track of their contributions and ensures compliance with IRS guidelines, thus maximizing HSA benefits.
