Preparing Invoices

Coronavirus (COVID-19)

Click Coronavirus Disease (COVID-19) to see whether the measures adopted by Revenu Québec apply to the information on this page.

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

However, as a registrant, your purchase invoices and other supporting documents (such as a written agreement or receipt) must provide specific information to justify your input tax credits (ITCs) or input tax refunds (ITRs). This information must be shown on one or more supporting documents according to the total value of the goods or services you purchased. Your supplier must provide you with this information in writing upon request. Your customers that are registrants may also request that information from you.


If a customer has a bill totalling $150 or more and requires a copy of it for ITC or ITR purposes, the customer may ask a restaurant establishment that is required to produce bills using a sales recording module (SRM) to provide a copy of the bill. The establishment can then give the customer the bill produced using the SRM as well as an additional document showing the customer's name and the terms of payment. That document must refer to the bill.

For more information, see Obligations of Persons that Are QST Registrants.

  1. An intermediary is a registrant that makes supplies on behalf of a supplier for which it is the agent or with whom the intermediary has entered into an agreement, or that facilitates the making of the supply.
  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.
