When you e-mail a paystub to an employee, QuickBooks uses the e-mail address provided on the Address and Contact tab in the employee record. If the employee's e-mail address is not provided in the employee record, you'll be prompted for an address when you e-mail the paystub.
To do this task
Open the employee's record.
Go to the Employees menu and click Employee Center.
Click the Employees tab, if necessary.
Select the employee from the Employees list and then click the Edit Employee... button.
Click the Address and Contact tab.
Enter the employee's e-mail address in the E-mail field and click OK.
