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

You can register online, by mail, by fax or by telephone. If you operate in Québec, go to Businesses operating in Québec and GST/HST program accounts.

Business Registration Online

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.

By phone

To get a business number and register for CRA program accounts by phone, call our Business enquiries line at 1-800-959-5525. For hours of service, go to Hours of telephone service. If you just want a business number, use Business Registration Online (above) instead.

Before calling, be ready to answer all the questions in Part A of Form RC1, Request for a business number and certain program accounts, and any other questions in the form about the CRA program accounts you want to open.

In Quebec, Revenu Québec generally administers the GST/HST.

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.
