Hi MikeyT
Thanks for your post. STP reports the Year-to-date (YTD) amounts each time you declare a payrun and the only amounts the ATO are interested in are the YTD amounts. If an error has been made in a payrun, you can either delete or reverse that pay, then reprocess the pay correctly which will update and correct the YTD amounts in STP. Another option for correcting errors is to create an update event by processing a $0 pay.
The ATO Business Portal will show all payruns as they don't allow deletion of STP reports. However, as they are only looking at the YTD amounts you just need to ensure those figures are correct at all times. You can check that the YTD amounts are correct by going to the Payroll reporting centre and downloading the report for the most recent report sent.
Please let me know if you need further help.
