Preparing Invoices

No special invoices or rules are imposed under the GST and QST systems, with the exception of those that apply to restaurant establishments.

However, you must provide your clients with certain information if they request it. They may need that information, for example, to claim input tax credits (ITCs) and input tax refunds (ITRs).

Mandatory billing in the restaurant sector

All restaurateurs must provide bills to their clients. Restaurateurs who are QST registrants must also produce the bill with a sales recording module (SRM).

For more information see the SRM-Compatible Printers and Obligations of Persons that Are QST Registrants pages under Mandatory Billing in the Restaurant Sector.

Information required on your invoices

Since your customers may, like you, be entitled to ITCs and ITRs, you must provide them with the information they need to claim them.

The table below presents the information that must be on your invoices based on the total value of the supply made to your client.

  1. An intermediary is a GST and QST registrant that makes supplies on behalf of a supplier with whom the intermediary has entered into an agreement.
  2. When both the GST and the QST are included in the amount of tax, you must show the amount of tax for each taxable supply and specify that the amount includes both the GST and the QST.
