The expenses that are typically included in the definition of Payroll or, in some policies, Wages are:
Fringe Benefits Tax
Workers’ compensation insurance premiums and/or accident compensation levies
Superannuation and pension fund contributions
Long service leave, and the like
Policies do vary in what falls within the definition, and it is necessary to take a few minutes to familiarise yourself with the definition of Wages or Payroll under the policy you are considering, to ensure that all costs are captured. Failure to do so could lead to an under-insurance problem in the event of a loss.
