It is possible that the taxpayer would have entered details of outward supplies but the same/some of them were not filed/submitted as the window of 1st to 13th had elapsed or as the details had exceeded Rs 50 lakhs limit fixed for the month. Such records which were saved but not filed/submitted are required to be deleted using the RESET button before furnishing Form GSTR 1 for the quarter. Now all the pending outward supply details of the quarter are to be filed in Form GSTR 1 of the quarter. New functionality is likely to be introduced which will either move/delete the saved invoices from IFF to Form GSTR 1.
