Do I need to pay Delaware payroll taxes even though all my employees are in Illinois?

Hello there, King. Allow me to share details regarding payroll taxes.

You'll only have to pay the Illinois payroll taxes since these taxes are calculated based on W-4 info and your employee's work location. For more details, you can refer to this article on how payroll taxes are calculated in QuickBooks Online (QBO): Understand how your payroll taxes are calculated.

If you want to remove the state from the tax list, ensure that no employee's work location is linked to the Delaware state. You can follow these steps to remove the unused work locations:

1. Go to the Gear icon, then Payroll settings.
2. From Work locations, select Edit.
3. Select Edit on the work location you want to remove.
4. Select Delete work location. Then select Save.

In addition, you can refer to this helpful article to learn how to electronically pay and file your federal, state, and local taxes in QuickBooks: Pay and file payroll taxes and forms electronically in QBO Payroll.
