I have an employee that wants me to increase the income tax taken off on his cheques. I cant seem to find a way to simply add $50 to his deductions

Thank you for posting your concern here in the QuickBooks Community, Jim. I'm happy to share more information about tax withholding.

You can update an employee's payroll information by opening their profile. You can add add the $50 as an additional withholding tax. You can follow these steps on how:

1. Go to Payroll and select Employees.
2. Click the employee's name.
3. Go to the Tax withholding section and click Edit.

4. Choose where to add the deduction. In Federal taxes, enter the amount for Extra Withholding. In state taxes, enter the amount for Additional Withholding.

5. Hit Save.

Moreover, let me share this article if you want to invite your employees to see their paystubs: Invite your employees to QuickBooks Workforce to see pay stubs, W-2s, and more if you use QuickBooks Online Payroll.

I'll be here if you still have questions about your payroll. Have a great day, and take care.
