You may need to adjust the employer contribution amount reported for your Health Savings Account (HSA) if either of these situations applies:
- Your employer's 2026 HSA contributions are included in Box 12 of Form W-2 with code W.
- Your employer made HSA contributions for the 2026 tax year during 2027.
If either situation applies, complete the Employer Contribution Worksheet to determine the correct amount to enter on this screen.
The amount you enter will adjust the employer contribution figure that was entered on your W-2. When a Code W amount is present in Box 12, that amount flows to Line 9 of Form 8889. The worksheet helps ensure the correct employer contribution amount is reported, especially when contributions were made after the end of the calendar year but still count for the tax year.
