Hi, I'm a Sole Trader in Australia who wants to learn how to use the Payroll feature to pay Sub Contractors Superannuation. Could someone please advice me on how?

Hello there, Aaron.
 

In QuickBooks, we can add your Subcontractor as an employee with the employment type of Superannuation Income Stream. Here's how:
 

1. Open QuickBooks, then go to Payroll.
2. Click Add Employee.
3. Fill in the necessary information.
4. Click Next to proceed to the Employment details.
5. Under the Employment Type, Select Superannuation Income Stream.
    

The STP tax category for the payee must be set as ATO-defined> Non-employee. You can set this up under Tax File Declaration after you complete the employment details by selecting Next.
 

After that, you can create a New Pay Run for your Subcontractor in the upper right corner. See screenshot below.
 

After creating a pay run for this Subcontractor, you'll be able to create a super batch payment for them. For more detailed information, refer to this article: Setting up Super Payments with Beam in QuickBooks Online.
