Before you can change a pay, you'll need to undo the finalisation. This lets the ATO know your payroll year information isn't complete. It also prevents the employee from pre-filling and completing their tax return.
Go to the Payroll menu and choose Payroll Reporting.
Click Payroll Reporting Centre.
Click the EOFY Finalisation tab.
Choose the applicable Payroll year.
Click the ellipsis button for the employee to be unfinalised and choose Remove finalisation. This option is only available for finalised employees.
