Cancelling T4 slips

Cancelling slips over the Internet

To cancel a slip, do not change any information that was contained on the original slip. Use summary report type code "A" and slip report type code "C."

For more information about cancelling information returns using the Internet, go to Amending returns.

If you cancel slips using the Internet, we may contact you to find out why.

Cancelling slips on paper

If you choose to cancel your amended return on paper, clearly identify the slips as cancelled slips by writing “CANCELLED” at the top of each slip. Make sure you fill out all the necessary boxes, including the information that was correct on the original slip. Send two copies of the cancelled slips to the employee.

Send one copy of the cancelled slips to any tax centre with a letter explaining the reason for the cancellation.

Do not file an amended T4 Summary.
