Changes to GST/HST Return Filing – Starting October 19, 2015

If you are registered for GST/HST, CRA will provide you with a new and unique access code on your GST34-2 Goods and Services Tax/Harmonized Sales Tax (GST/HST) Return for Registrants or GST34-3 Goods and Services Tax/Harmonized Sales Tax (GST/HST) Electronic Filing Information. You will also be able to change your access code to one of your own choice at This will be applicable to all future filings.

If you receive the GST34-3 package, you will now receive one package for the entire fiscal year instead receiving a package each time you have to file. This package will contain your access code, a list of your reporting periods and filing deadlines for that fiscal year, and the remittance vouchers for each period during the fiscal year.

These changes will take effect October 19, 2015.
