Hi @hartsx5,
Thanks for getting in touch! I get that you're having some trouble with payruns and STP not matching up in the ATO's records, even after updating. This can be a bit tricky since it involves both MYOB and ATO systems.
First off, make sure all your payruns have been properly reported and accepted in MYOB. You can double-check this in the STP reporting center. If you find any payruns that haven't been accepted, try resending them. Another thing I would suggest is to compare all payroll reports, such as the payroll activity report and the payroll register report. This can help you figure out where the differences in numbers are coming from. Once these two reports match, you can process an STP update event to sync the YTD amounts in STP.
Let me know how you'd go on this.
Kind regards,
Shella
