(Canada only) For each employee who has worked in more than one province and/or worked under more than one payroll program account for the tax year, you must record multiple T4 slips.

1. Double-click on an employee on the T4 Employees tab.
   The system auto-generates information based on payroll account, tax year, and employee.
2. If needed, enter a new, valid employee number in the Employee field or press F4 to select from a list of employees.
   The system auto-generates information based on payroll account, tax year, and employee.

   Note: Beginning December 2021, you must use Aatrix to create and submit original, amended, and canceled T4s. Therefore, the Return Type field is disabled and cannot be used to indicate what type of T4 you are submitting. However, it will default to O-Original for new slip records. To preserve historical data, all existing records will retain their selected settings.
3. In the T4 Box Number field on the T4 Box Items tab, enter the corresponding box numbers for the employee's accumulated amounts. Press F4 to select from a list of valid box numbers.
4. In the Amount field, enter the amount for the box number.
5. On the T4 Other Codes tab, in the T4 Code Number field, enter the corresponding code numbers for the employee's accumulated amounts that relate to employment commissions, taxable allowances and benefits, deductible amounts, earnings, and so on.
6. In the Amount field, enter the amount for the code.
7. Save the record.
