Before you start, we recommend that you complete the following steps:
Once you have completed these steps, call the toll-free telephone number using a touch-tone phone, and enter your return information when prompted by the automated messages. When you successfully file your return, you will be given a six-digit confirmation number for your records.
To use GST/HST TELEFILE, you will need the four-digit access code printed on the electronic filing information sheet (Form GST34-3) or the personalized return (Form GST34-2) that you received in the mail.
If you've misplaced your access code or didn't receive one in the mail, you can get a new code by using GST/HST Access Code Online or calling the e-Services Helpdesk.
If you are the coordinator of a closely related group of corporations (i.e. you have filed election GST303) and you file returns electronically, you must still send your letter of direction to your tax centre.
