Each time a Pay Event is successfully submitted to the ATO, the header displays in your business portal. If you restore to previous data, i.e., a backup taken before the event being reported, and report another event for the same period, your business portal will display both events. This data cannot be removed from your business portal by the software provider. You will need to contact the ATO for advice on how to remove or edit the data in the ATO's BAS portal.
To avoid duplicate events, if you need to restore to a point before a pay event has been submitted, you can do a Full File Replacement to replace that event when you report your STP. However, before proceeding:
You must obtain the submission ID of the event you are replacing before restoring the data.
You must be replacing the latest pay event. That means that you cannot have any pay, update, or adjustment events reported since the pay event you wish to replace.
Consider whether you could correct the transaction in the next period, e.g., Manual Calculation.
For information on Full File Replacements, see Full File Replacement for STP.
Note: What is reported for your employees in their MyGov Income Statements is always the current year to date values. Each event reported overrides the data based on the date and timestamp of the last event reported, and the data is not duplicated in their Income Statements.
