Hi SharonSL,
That would be confusing when you’re only just getting this started. This error usually means the contractor's Employment basis is set to "Other (not reportable)", which isn't accepted if that contractor needs to be reported through STP.
The quick way to check it is:
-If this contractor should be included in STP, update their Employment basis to a valid reportable option, then try lodging again.
-If they're only being paid super and aren't meant to be reported through STP, "Other (not reportable)" can stay as is and you should be able to continue with the super payment.
Because contractor reporting can vary, it's worth confirming the right treatment with your accountant or the ATO before making any changes.
Regards,
Earl
