Hi tgtfencing-
From what it sounds like you're looking for the Software ID needed to enable STP for your business with the ATO. You can find the unique Software ID by following the steps below.
- Select the Employees tab.
- Select the Payroll Settings, underneath the Business Settings column, select ATO Settings
- Of the two tabs, select Electronic Lodgement & STP
- Here you will find your Software ID
If this isn't what you're looking for, no dramas, let me know a little bit more about the ID you are looking for and we can advise on how to get it.
Hope that helps.
