EM error codes indicate ATO backend errors. Software providers cannot access the ATO backend, so they cannot confirm what triggers these errors. Software providers do not have access to the backend data that the ATO uses to validate received information. As a result, we cannot check for these backend errors during our error checks.
EM error messages usually include steps to resolve the issue. If the message does not explain how to fix the error, the ATO must provide further guidance, as they generate and supply these errors. The ATO includes an error code and message to help resolve the issue.
When you receive EM errors, check the validation report for that specific return. You will find a message ID and a transaction ID, unique identifiers for that lodgment, provided by the ATO. If you give the ATO these numbers along with the error details, they can advise you on how to resolve the issue.
We recommend speaking with a second-tier ATO consultant, as they can usually identify what causes the error. The ATO can also guide you on how to enter the data and complete the return for that specific case.
