Validation of QST and GST Numbers
Did you know you can use the following online services to verify that a business billing you QST and GST is a QST and GST/HST registrant?
- Validation of a QST Registration Number (Revenu Québec)
- Confirming a GST/HST account number (Canada Revenue Agency)
Your requests for input tax credits and input tax refunds could be refused if the business is not a registrant.
