Thanks for bringing this to my attention. Let's investigate why you can't submit your GST summary to ATO, user22115.
Have you encounter an error message when submitting the GST summary? It's possible the electronic lodgement is not completed properly. It could be also the ATO have already received the event and that it has been lodged multiple times.
To successfully submit your GST, you can check out this link to resolve some common lodgement issues in QuickBooks Online (QBO): ATO Lodgement Issues.
If the same thing happens, I'd suggest reaching out to our Payroll Support Team. They'll pull up your account in a secure environment and help you submit it to ATO.
Also, due to COVID-19 we have limited staffing and have reduced our hours to 6am-6pm PT Mon-Fri.
