Free Online GST/HST Registry

The Canada Revenue Agency (CRA) GST/HST registry allows you to check to see if a business is registered to collect GST/HST.  To use the registry, the following information must be provided:

bulletGST/HST number (first 9 digits), also known as business number, or registration number
bulletbusiness name as registered with Canada Revenue Agency (CRA)
bulletdate of the transaction

See also the article on the free online QST registry provided by the Quebec Revenue Ministry.

GST/HST Registry Warning

An August 2012 article by Torkin Manes LLP pointed out that the GST/HST registry only checks the first 10 characters (including spaces) in the business name, so it is possible to get erroneous results from the registry.  I checked this and confirmed that the article is quite correct.  I entered the GST/HST number of one corporation with the name of a different corporation (first 10 characters of the names identical), and was given confirmation that "the GST/HST number was registered on the transaction date entered".  We recommend always saving a pdf of, or printing, the confirmation page for your records, as it may help if the transaction is later questioned by CRA.

Tax Tips:

For businesses:  When dealing with a new vendor, check to see if their GST/HST number is valid.  This will help ensure that you will receive your input tax credits.

For individuals:  You can check to see if a firm's GST/HST number is valid, so you don't pay GST/HST unnecessarily.
