Payroll information

Businesses need to estimate the payroll information for the insurable earnings they will pay their employees for the current year. This information is reported on the employees’ pay stubs or T4 slips as gross earnings, including deductions for income tax, CPP and employment insurance. Insurable earnings can also include earnings not reported on a T4 such as room and board, bonuses and commission s.

Insurable earnings are subject to a maximum amount for each employee. Refer to this to calculate the premium and insurable earnings.

 As a business, you are responsible for insuring the following:

  • Anyone you employ in your business under a contract of service, including family
