Using AccountRight 2020.3? You don’t need to follow the process described below to remove an incorrect termination payment from the Payroll reporting centre. Instead, just reverse the pay in AccountRight and you’ll be prompted to submit the reversal to the ATO for STP reporting. This will automatically remove the incorrect payment.
To undo a termination payment, you'll need to remove it from the Payroll reporting centre to notify the ATO. And if you haven't already, you'll also need to remove the termination payment transaction from AccountRight.
You might also need to do this if you have duplicated ETP payments in the Payroll reporting centre.
