What is a Payroll Account?
A payroll account is used by employers to identify themselves when dealing with the Canada Revenue Agency (CRA) for the purpose of remitting income tax deductions, Canada Pension Plan contributions, and employment insurance deductions.
The first 9-digits of this 15-character account number are also known as the business number (BN). The BN is a unique federal government numbering system that identifies your business and the various accounts you maintain.
You have to register for a payroll account before the first remittance due date. Your first remittance due date is the 15th day of the month following the month in which you began withholding deductions from your employee's pay.
