Short answer: You can determine how much you contributed to your HSA for the tax year by checking Box 12 on your W2 for code W and adding any contributions not made through payroll deductions.

Using W-2 Box 12 to find HSA contributions

When it comes to determining how much you contributed to your HSA (Health Savings Account) for the tax year, your W2 form plays a significant role. Your W2 form contains valuable information about your HSA contributions, making it easy for you to track your contributions. Here's how you can find out on your W2 what you contributed to your HSA:

  • Look for Box 12 on your W2 form: Your HSA contributions are typically reported in Box 12 using the code W.
  • Review Box 12 with Code W: The amount shown in Box 12 with Code W represents your total HSA contributions for the year. This amount includes both your contributions and any employer contributions made on your behalf.
  • Calculate your contributions: If you made contributions outside of your employer's payroll deductions, you should add those amounts to the total shown in Box 12 with Code W to get your total contributions.

Understanding your HSA contributions is crucial during tax season, and your W2 form, particularly Box 12 with Code W, serves as a helpful guide. This box highlights the contributions made to your HSA, including both personal and employer amounts, making tax preparation easier.
