Amending a return using the T4 Desktop application

The purpose of amending or canceling a slip is to make changes to a slip that has already been filed. Do not resubmit slips that have no changes when submitting your amended slips. New or missed slips are submitted in a new return.

To amend or cancel any of the previously filed slips in a return, start by opening the previously filed return and choosing "Amendment" in the first radio button on the top of the Employer Information screen and click "Accept":

A message window will appear, asking you to confirm that you are changing the return to an amended return. Click "Continue". The list of T4 slips screen will appear as follows:

Highlight the slip you want to amend and click on the Modify button. Click on the Delete Button if this slip does not require any amendment. It will be removed from the return. Once the Modify button is clicked, the following screen will be displayed. Every slip will have a new radio button asking you to choose either cancelled or amended.

Select Amended to correct a slip you have already submitted, or select Cancelled to delete a slip you have already submitted. Amending a slip will overwrite the information on the previously filed slip. Cancelling a slip will delete the previously filed slip. Do not resubmit slips that have no changes when submitting your amended slips. On the slips that need to be changed, amend the incorrect information and leave the remaining information unchanged. When completing the amended summary, include only the totals from the amended slips.

If you have opened your previously saved file, ensure you delete all the slips that do not need any amendments. Save the file using "Save As" and give it a second name. This will leave your original return intact, and create a second file containing the amended slips. Submit this file. If you create a new return, create and submit only the amended slips.
