Adding CRA program accounts to your business number

Generally, when you register for a Business Number (BN), you also register for the program accounts you require at that time.

If your business expands after you register for a BN, you might need to add other program accounts to your BN.

The five major CRA business accounts are:

  • RT - Goods and Services Tax/Harmonized Sales Tax
  • RP - Payroll
  • RC - Corporate Income Tax
  • RM - Import/Export
  • RZ - Information Return

Before adding any program account, go to When you need a business number or CRA program accounts.

If you determine that you need to add an account, go to How to register for a business number or CRA program accounts.
