Which Box on W2 is HSA Contributions? - Understanding HSA Contributions for Tax Purposes

When it comes to understanding your HSA contributions for tax purposes, it's important to know which box on your W2 form indicates your contributions. The box you need to look for is Box 12 with a code W. This box specifically shows the total amount of HSA contributions made by you and/or your employer during the tax year.

HSAs, or Health Savings Accounts, are tax-advantaged accounts that allow individuals to save for qualified medical expenses. Contributions made to an HSA are tax-deductible, meaning they can lower your taxable income for the year.

It's crucial to accurately report your HSA contributions on your tax return to ensure compliance with IRS regulations. By knowing where to find this information on your W2, you can easily track your contributions and report them correctly.


Understanding HSA contributions is vital for managing your finances, especially during tax season. Look for Box 12 on your W2, which is marked with a code W to find the total contributions made by you and your employer throughout the year.
