Hello there, jackie27
Let me explain how to generate tax reports in QuickBooks Online (QBO) Singapore.
If you created the report from a menu or the Reports page, the report may show transactions for today's date only. You can choose the start and end dates of the transactions listed by adjusting the dates in the From and To fields at the top of the report.
For more details on how the GST Detail Report works in QBO, see these articles: GST Detail Report.
