Hi Caz95,
Thanks for reaching out.
I understand corrections should be made in the reports sent to the ATO. Since this is for terminated employees there are a couple extra steps to be done.
If you have already sent the incorrect YTD figures for the terminated employees, first remove the termination on the card file, remove the employee on STP employee termination, then you could send an update event for 2022-2023 FY, make sure that the YTD figures are correct in the verification report. After which you can return the employee's termination date, return the employee to the STP employee termination, then finalize.
Let me know if you require any further assistance with this. I'm happy to help.
Cheers,
