T4 - Identification
Employee Name and Address
Enter the employee’s last name, followed by the first name and initial. If the employee has more than one initial, enter the employee’s first name followed by the initials in the “First name” box. If you enter only the employee’s initials, enter them at the beginning of the “First name” box. Do not enter the title of office or courtesy title of the employee (such as Director, Mr., or Mrs.). Enter the employee’s address, including the province, territory, or U.S. state, Canadian postal code or U.S. zip code, and country.
Note: Complete the T4 slip using the employee’s name, not the company name. If you pay an amount to a proprietor or partner of an unincorporated business, do not issue a T4 slip. Instead, issue a T4A slip.
Box 10 – Province of Employment
The province or territory of employment you enter depends on where your employee has to report for work. For more information, consult the “Which tax tables should you use?” section in chapter 1 of Guide T4001, Employers' Guide - Payroll Deductions and Remittances.
Enter "ZZ" if an employee worked in a country other than Canada or the U.S., or worked in Canada beyond the limits of a province or territory (for example, on an offshore oil rig).
For any employee who worked in or whose employment was located in more than one province, territory, or country in the year, complete separate T4 slips. For each location, indicate the total remuneration paid to the employee and the related deductions, such as CPP/QPP contributions, EI premiums, and tax.
Box 12 – Social insurance number
Enter the employee’s social insurance number (SIN) as it appears on the employee’s SIN card.
