GST Aggregate Turnover Difference

This discussion addresses a discrepancy between a business's book sales figures and the aggregate turnover shown on the GST portal for FY 20-21. The user noted a difference of over £11,000, with the portal figure appearing to be higher. The advice given is to cross-reference the sales figures recorded in the books against GSTR-1 and GSTR-3B filings to identify the source of the variation.
