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.
As part of our continuing efforts toward sustainable development, we no longer mail out the pre-printed T4 Summary. You can get a T4 Summary here or by calling 1-800-959-5525.
Completing the T4 Summary
For detailed completion instructions, see T4 Summary line instructions.
- 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?
- Complete 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.
