Hi Princess_R ,
I've had the same issue here for Gross payments,
- Payroll Activity = Payroll Register ≠ STP YTD Report
Except that I've found that the difference was due to Task Allowances and Notice in lieu payments on my end.
The Task Allowances (ATO category: allowance type KN) and ETP (Type O) payments are still under Gross Payments in the Payroll Activity and Payroll Register Report, while they are not counted towards the Gross payments in the YTD report for some reason.
I've just submitted to ATO as is, since the difference still appears on the employees' individual YTD report as "Allowance - tasks" and "ETP-taxable component - O".
Could you kindly advise if what I've done is correct/incorrect please?
Much appreciated.
