Superannuation is a mandatory payment for all employers to help their staff save for their retirement.
If you pay an employee more than $450 in a calendar month before tax, you will be required to pay the Superannuation Guarantee (SG) of 9.5%.
The ATO have a comprehensive guide to paying super for employers on their website so you understand your liability.
Australian Government's Small Business Superannuation Clearing House lets you pay your superannuation contributions in one transaction to a single location. This free service reduces the time and paperwork involved in making multiple payments to different superannuation funds.
