What is a payroll deductions account

A payroll deductions account is an account number assigned to either an employer, a trustee, or a payer of other amounts for employment to identify themselves when dealing with the Canada Revenue Agency.

This 15-character payroll deductions account number contains the 9-digit business number (BN). The BN is a unique federal government numbering system that identifies your business and the various accounts you maintain. The payroll deductions account number consists of:

  • 9-digit BN
  • 2-letter code for the type of program (for a payroll deductions program, the letters are RP)
  • 4-digit reference number to identify each account in a program a business may have

Depending on the type of business you have, you may need to register other types of programs accounts or open a separate payroll deductions account. The 9-digit business number will not change, but other letters or reference numbers will be added to the BN.

Example

A company requires a GST/HST and two payroll accounts. The account numbers would be:

Example of account numbers

Business number 12345 6789
