How to register for a business number or Canada Revenue Agency program accounts

Best for businesses with simple registration requirements.
You can use Business Registration Online to get a business number. You can also register for one or more of the most common Canada Revenue Agency (CRA) program accounts:
- GST/HST program account (RT)
- payroll deductions program account (RP)
- import-export program account (RM)
- corporation income tax program account (RC)
By mail or by fax
If you just want a business number, use Business Registration Online (above) instead.
To print a form, go to Form RC1, Request for a business number and certain program accounts or, to order a form, go to Get a form or publications.
Fill in form RC1. Once you have completed the form, mail or fax it to your nearest tax service office or tax centre.

For more information, see the Revenu Québec publication IN-203-V, General Information Concerning the QST and the GST/HST, available at Revenu Québec, or call 1-800-567-4692.
