This discussion explores whether individuals registered for GST and earning business income also need to report interest income from savings accounts or loans given to others in their GSTR 1 and GSTR 3B filings. While some argue it's exempt and not reportable, others contend that interest income falls under the definition of 'supply' in the CGST Act and should be declared, even if as exempt income. The consensus leans towards reporting it, particularly when it's considered part of turnover, with suggestions to report it annually or as it's credited.
