Adding T4 slips

After you file your information return, you may discover that you need to send us additional slips. If you have original slips that were not filed with your return, file them separately either electronically or on paper.

Adding slips on paper

When submitting additional slips on paper, clearly identify the new slips by writing “ADDITIONAL” at the top of each slip. Send one copy of the additional slips to any tax centre with a letter explaining the reason for the addition.
