Welcome to the GST/HST Registry

System maintenance

As a result of systems maintenance, the GST/HST Registry will not be available on Sunday, September 21, 2014, from 3 a.m. to 8 a.m. (Eastern time).

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.
