QuickBooks Online will include all properly configured local taxes automatically. Our extensive guide on How QuickBooks Populates W-2 explains that Local Income, Taxes, etc. appear in Boxes 18, 19, and 20. In order to ensure these items have been set up correctly, head to the Community link here and search for [Your State] Local Tax for further instructions. If you'd like, you can also share the state you're working with here and I'll be more than happy to lend a hand.
If you're able to determine the taxes weren't set up properly, since this information is concerning a prior tax year, you'll need to reach out to our awesome Payroll Support Team so a correction can be filed. Here's how:
