Adding accounts to your business number (BN)

Generally, when you register for a 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, see Do you need a business number or program account? and Before you register.

If you determine that you need to add an account, see How to register.
