As an employer you have an obligation to pay super contributions on behalf of all your eligible employees. These contributions are in addition to your employees’ salaries and wages.
This compulsory contribution is called the superannuation guarantee and it requires you to:
pay super for your eligible employees
contribute to the correct super funds, and
pay contributions by the cut off date each quarter.
There are also some circumstances where you do not have to pay super for employees, you can check a list of these circumstances at Who is not eligible for super.
