If you are filing your return electronically, do not send us a paper copy of the slips or summary. For more information, go to Filing Information Returns Electronically (T4/T5 and other types of returns).
If you are filing on paper, use the T4 Summary, Summary of Remuneration Paid, to report the totals of the amounts reported on the related T4 slips. Send the original summary and the related slips to the Ottawa Technology Centre.
Filling out the T4 Summary
- Report amounts in Canadian dollars and cents, even if the amounts were paid in another currency. To get the average exchange rates, go to What are the average exchange rates?.
- Fill out a separate T4 Summary for each of your payroll program accounts. The totals you report on your T4 Summary have to agree with the totals you report on your T4 slips. Errors or omissions can cause unnecessary processing delays.
- If you have not reported any amounts on the T4 slip or Summary, there is no need to send us a form.
Detailed T4 summary instructions
In the area at the top of the T4 Summary, enter the 15-character payroll program account number in the “Employer’s account number” box. It is the number that you use to send us your employees’ deductions. Enter your operating or trade name as well as your address below the payroll program account number.
You cannot change your address using the T4 summary. To do this contact your tax centre.
Enter the last two digits of the calendar year for which you are filing the return.

If the amount on line 82 is more than the amount on line 80 (and you do not have to file another type of return for this account number), enter the difference on line 84.
