Welcome to the GST/HST Registry

The GST/HST Registry lets you validate the GST/HST number of a business, which helps to ensure that claims submitted for input tax credits only include GST/HST charged by suppliers who are registered for GST/HST. You can also use the GST/HST Registry to verify GST/HST registration for other purposes.

Note:
You can validate the QST registration number by accessing the QST Registry on the Revenu Québec Web site.
