Am using the STP app. Have registered my ID number with ATO who confirm they can "see" my ID associated with my ABN which is 42697228266. But my first pay run for 19/20 showed "Submitted to ATO" followed a few minutes later by "Declined by ATO". There is no other error message except to "Review and Adjust". I have repeated my first run five times over several days, shutting down and restarting between runs. They all show the same "Declined by ATO". The ATO people say they can see no sign of any pay runs from me. Why are my Pay Runs being declined by ATO?
