Hi Carmel,
We do not process through MYOB Payroll at all. Our attempts to process through payroll resulted in an error when updating to ATO STP reporting. The ATO website states that super contributions to contractors are to be reported Via STP2 if the accounting software can support it . As MYOB does not currently have the functionality to treat this corrrectly it is clear that the MYOB accounting software does not support it.
The contractors we have are paid on the basis of an hourly rate. Whilst they may utilize their own tools and equipment, they do not provide materials. They work exclusively for our business and for all intents and purposes, fit the defination of being deemed an employee. Therefore, in terms of calculating the super applicable it is simply the total of the invoice they provide each week multiplied by the SGL rate for super.
In your case it would seem that you need some guidance from your external Accountant and/or ATO which is sounds like you are in the process of getting.
Hope that helps and good luck with getting clarification on this.
Cheers
Lynne
