Hi ComCons,
To address the issue where the PAYG withholding has been overstated in your STP report, check first the STP reporting center to identify any duplicate submissions for the specific payroll period. You might consider processing a negative pay run to offset the duplicate amount reported.
If a duplicate submission has been sent, you may need to contact the ATO to explain the situation and ask for guidance on adjusting the overstated amount. The ATO may have a process for rectifying such errors.
For further assistance, consulting with your accountant or a tax advisor can ensure that your adjustments comply with ATO requirements.
Regards,
Sai
