STP finalisation on our clients file doesn't balance to the Payroll Activity Summary, which is correct and the Salary Sacrifice reconciled. I can see 2 payruns a few months ago, where the payruns have been reversed and the correct payrun entered fine but the YTD totals are not correct. So, I need to update the STP submission to balance to the Payroll Activity Summary. From reading support notes, I think kthis can only be done on an amended pay event lodgement. Is this correct?
