I don’t believe the ATO allow you to delete an STP entry at all. You have to correct any mistakes by an Update Event. And while MYOB does not have an update event function yet you can still create one. Xero does not allow deletion of STP entries either.
In the Payroll Reporting Centre any file with Status "Not Sent" will stay there even if you're no longer planning to send it. We should be able to delete any file that we are no longer planning to send.
Need MYOB to allow deletion of payroll entries on the ATO reporting page. If you happen to make an error in processing a pay, you can delete it from MYOB payroll itself but not the ATO reporting centre if it has not been sent to ATO.
You absolutely need to be able to delete it - we have had clients approve, just because it is there where they thought they had updated the entry to the correct details.
