Thanks for your post. STP sends the up-to-date Year-To-Date (YTD) amounts each time you send a report and each report overrides the previous one. This means that if those pay runs were processed before STP was set up they were included in the YTD amounts in the first STP report.
If those pay runs were processed after STP was set up, the Payment date was in the past. You would have received an option to select New pay run or Updated pay run when recording those pays. If you selected Updated pay run only the YTD amounts are sent as this is an Update event. This means that the pay period amounts will be zero in the STP report. When you select New pay run both the pay period and YTD amounts are sent.
As the ATO are interested in the YTD amounts you need to check these are correct by clicking on the most recent STP report and View employee YTD report. Check the YTD amounts in this report match the AccountRight payroll reports.
