Rectification in september return

This discussion addresses rectifying tax and sales errors in a September GST return where the incorrect amount exceeds the September figures. The consensus is that transactions from a previous financial year (like January 2020) cannot be directly adjusted in subsequent months' GSTR-3B filings after the September deadline. The recommended approach is to correct these errors in the annual return (GSTR-9) for the relevant financial year, provided the tax was paid in the incorrect return.
