Business Number

A Business Number, or BN, is the Canadian business identifier that supports payroll registration and employer payroll administration.

From a payroll perspective, the Business Number matters because employer payroll reporting and remittance need the employer to be identified correctly. It is part of payroll setup infrastructure, not part of the employee paycheck.

Why Business Number Matters

Business Number matters because it affects:

• employer payroll registration
• payroll reporting and remittance setup
• the link between payroll accounts and the correct employer identity
• Canadian payroll administration accuracy

It matters because payroll can be calculated correctly and still be operationally incomplete if the employer registration side is not set up properly.

Where It Appears In Payroll Workflow

The Business Number appears during payroll setup and later employer follow-up work. In practice, payroll teams may use it to:

• establish payroll-related accounts
• prepare employer payroll reporting
• support payroll remittance activity
• match payroll records to the correct employer identity

That makes it a foundational employer payroll identifier in Canadian payroll.

Simple Example

A new employer starts Canadian payroll and needs to set up the payroll administration side correctly.

The Business Number helps identify the employer and supports the payroll account structure used later for reporting and remittance.

Common Confusion

Business Number is often confused with:

• Payroll Program Account, which is the payroll-specific account under the broader identifier structure
• TD1, which is an employee payroll setup form
• T4, which is a year-end payroll slip
• Employer Identification Number, which is the U.S. employer identifier concept
