Information for Payroll Service Providers
If, as part of the payroll services you provide to an employer, you prepare and file RL slips and summaries of source deductions and employer contributions, you must enter the employer's name on all RL slips and the employer's name and account number on all summaries.
An employer's account number is composed of
- 10 numbers (the identification number); and
- the letters “RS” followed by 4 numbers (the file number).
Account numbers look like this: 1234567890RS0001.
Note that we assign an account number when an employer either registers for source deductions or makes its first remittance of source deductions.
For more information, see Registering for Source Deductions and RL-1 Summary – Summary of Source Deductions and Employer Contributions, or consult the Tax Preparers' Guide: RL Slips (ED-425-V).
