This article applies to Wave Payroll in Canada.
During Wave's Payroll Setup, you will be asked to enter your CRA Payroll Account Number. Here's more detail on how to get your business' payroll account number, if you don't already have one.
In order for Wave to submit payroll source deductions on your behalf (remittances), you'll need to register for a payroll account with the Canada Revenue Agency (CRA).
Most of the time, you can register for a payroll number online through the CRA. Visit the Canada Revenue Agency for more information, or to apply.
You can also apply from your local business registration office, which is run by your province. For more information about starting a business in Canada, visit this Government of Canada website.
Once you have your CRA number, you can set up Wave to remit payroll taxes to the CRA on your behalf.
