Yes, @kashifra. We can manually upload W-4 in QuickBooks Online.
Let me show you how.
If you recruited a new employee, invite them to enter their W-4 information or enter it yourself. If your employee provided you with an updated W-4, enter that information.
Here's how:
Navigate to Payroll, then to Employees.
Choose your employee.
Select Edit from the Tax withholding menu.
Fill in the relevant information from your employee's W-4 in the Federal Withholding section. If they claim exemption on their W-4, select Exempt from the Filing Status dropdown.
