Give your QST registration number before completing your transactions
Are you registered for the QST under the general system? Give your QST registration number when making a purchase from a supplier outside Québec or an operator of a specified digital platform whose QST registration number starts with “NR” so you don't have to pay the QST. (See the list of suppliers outside Québec that are registered for the QST on our website.)
If you don't give your QST registration number when making a purchase of property or a service provided in Québec, you'll be charged the QST. If this happens, you'll have to contact the supplier or operator directly to be refunded.
For more information, see “Purchases made from suppliers outside Québec or operators of digital platforms” on the Input Tax Credits (ITCs) and Input Tax Refunds (ITRs) page.
