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.
