How to run the payroll of a Canadian citizen with a W-8BEN?

Welcome to the Community, @FAD.

To run this employee's payroll without withholding any taxes, he must be set up as tax-exempt in QuickBooks Desktop (QBDT). This can be done by going to his Payroll Information.

Here's how:

1. Go to the Employees menu at the top to get to the Employee Center.
2. Double-click the name to open this information.
3. Select the Payroll Info tab at the left pane, then tick the Taxes option. 
4. On the Federal tab, pick Don't Withhold in the Filing Status drop-down. 
5. Proceed to the State tab and choose Don't Withhold again Filing Status drop-down
6. Hit OK to complete the process. 

Once done, run his payroll to double-check. For more information, consider checking out these articles:
