Line 001 - Business number (BN)

Federal Line 001 - Business number (BN)

The BN is a 15-character number composed of three parts. The first nine characters identify your business. The "RC" identifies the corporation income tax program. The last four characters identify the particular program account.

On line 001, enter your BN for income tax purposes. Enter "0001" as the program account identifier unless the CRA has advised you to use a different one. You will find the corporation's BN on previous notices of assessment, account statements, or remittance forms. For more information, go to canada.ca/business-number.

Note
If you are a non-resident corporation that needs a BN, you have to give the CRA a copy of your certificate of incorporation or amalgamation before it can assign a BN to you. You also have to give the CRA documentation for any amendments that may have taken place.
