Can we add the state withholding to be filled out electronically on workforce

Thanks for sharing this concern with us, @seabird. Let me provide details to help you share the state tax form with your employees.

The option to add the state withholding to be filled out electronically on Workforce is currently unavailable. If you e-file the state tax form, you can consider downloading a copy from the archive section in QuickBooks or secure a copy of the form if filed manually. Check this article for detailed steps to help you view the e-filed and manually filed tax forms and payments: View your previously filed tax forms and payments.

Regarding including the state tax in your online setup, you can manually enter the information on the employee profile. Refer to the steps below:

1. Go to Payroll, then Employees.
2. If your employee is new, select Add an employee.  If an existing employee moved to a new state, choose your employee from the list. 
3. From Employment details, select Start or Edit.
4. Select or add the work location where you’re required to pay State Unemployment Insurance.  If you have remote employees, the work location may be different than where your employee physically works. Then select Save.
5. From Tax withholding, select Edit. Go to the State withholding section. If you see two states:
6. When you see a Local Taxes or Other Taxes section, select the applicable taxes and enter the rates. 
7. If you or your employee are exempt from any taxes, select the applicable tax(es). 
8. When finished, select Save.
