STP Error: A record with the same submission ID already exists

A record with the same submission is already exists. We were unable to process your submission because we already have a submission with this submission ID.

This indicates the submission has already been previously submitted and accepted. 

We have seen responses from the ATO "get lost" and a response is not sent from the ATO that the submission is successful.

Solution: You can check with the ATO or through support quoting your submission ID. An example of the pay event reference is displayed above as "PAYENNT-89123591763-6841".  

Note

There is a "Submit as new" option available in the "Resubmit" tab.
