Hi ChrisD55,
In order to correct this, you will need to lodge an Earnings Reset Event for all employees that have been reported with incorrect details. Put simply, the purpose of the earnings reset event is to allow businesses to lodge a $0 earnings event via STP for all employees who have been reported with incorrect business/employee details. Once you have lodged it, you need to correct the business details, ensure the new/correct ABN is enabled for STP and lodge an amended finalisation event.
This article will provide you the steps to create and lodge the Reset. Locate your correct scenario in the list (it sounds like you'll be looking at How to correct lodging STP events when the wrong ABN was used, but review all options to ensure your specific situation is addressed) and follow the guide to complete the Earnings Reset. Once you have done so, correct the ABN and any other information required. You will then need to enable STP integration for these new details otherwise your future lodgements will fail - see here for instructions on doing so either online or by calling the ATO.
Once you have integrated STP for the correct ABN, you will need to create an Amended Finalisation Event. This option will only appear after you have successfully lodged a finalisation event with the ATO. This guide will take you the process of doing so. Finally, I would encourage you to reach out to our Support Team directly on 1800 046 038 if you require clarification on any of these points or encounter difficulties/errors or so on as they can walk through the process with you and troubleshoot any issues you may come across.
Feel free to reply if you have further questions as I'm here to help!
