Hi skinner,
That definitely make you stop and double-check. If both pays are still showing in the Payroll Activity Summary and in STP reporting, a good first step is to compare your Payroll Register, Payroll Activity, and YTD Verification reports to see whether the reversal has flowed through correctly across all three. Sending an update event is the right move, as that refreshes the year-to-date figures on the ATO side. But if the original pay and the corrected pay are both still showing in your payroll reports, that usually means the file itself still needs checking rather than it being just an STP refresh issue.
You can also work through this guide for report mismatches and update events: End of year finalisation with Single Touch Payroll reporting. If the reports still don’t line up after that, it’d be best to reach out to our support team via the Contact Us page so they can take a closer look at the reversal and how that pay has been recorded.
Cheers,
Doreen
