1. What is an access code?

An access code is a one-time security key used to identify a specific GST/HST return. It is a four-digit number printed on the electronic filing instruction sheet (Form GST34-3) or the personalized return (Form GST34-2) that you received in the mail.

2. Will my access code be the same for each filing period?

No. Your access code is a one-time security key. You will get a new access code for each filing period.

3. How can I get an access code?

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.

4. Are there any helpful hints on how to use the service?

Completing your GST/HST return online is as straightforward as completing a paper return. Here are some things to know about filing your return:

  • review the checklist of items on the Ready to file page before you begin filing your return;
  • enter all amounts in Canadian funds;
  • if you end your filing session before confirming that you want to file your return, the information you entered will not be saved; and
  • after you successfully file your return, we will send you a confirmation number that you should print and keep with your records.

5. What happens to my return after I have filed it using GST/HST Internet File Transfer?

Once you submit and send the .tax file, you will immediately receive a six-digit confirmation number and we will start to process your return. Print the page with your confirmation number and keep it with your records.

Returns filed using GST/HST Internet File Transfer are reviewed like all other returns. You should keep your working copy for your records. It and any other information you use to prepare your return are subject to audit and must be retained for verification purposes.

6. Can I use GST/HST Internet File Transfer to change a return that I've already filed?

Returns can only be adjusted electronically using the My Business Account (MyBA) portal. If you do not already have a MyBA user ID and password, you can create one at My Business Account.

If you are not registered with MyBA, send your adjustment request, in writing, to your tax centre.
