Wave collects a few additional pieces of information to take advantage of the CRA's e-filing option.
Note: The "E-File Transmitter Info" (full name ) should be that of the person filing the T4A. The "Contact Information" (full name and phone number) will appear on your T4A Summary and should be for the person who can answer questions about the return, if CRA needs to get in touch. - If information is missing, a red Fix Missing notification appears. You must fill in the missing information to continue.
- When all of the information is correct, click the Generate T4As button.
-
A screen with a short to-do list will guide you to complete your T4A filings.
- Download the T4As to distribute them to your contractors.
- Download the XML file for internet file transfer and upload it to the CRA website.
