i tried to file the return of GSTR 3B for the month of August on Sept 20th but while submitting through DSC the portal denied saying that there are dues to be paid and after clearing all the dues then only it would accept.But to my surprise the ITC in July was Rs.3,50.550 and the sales in the month of August is also much ledder than the purchases of the same month say:Total sales were-22,54,500(within state) and purchases(outside) were 32,45,000 and 12,26,000(within state),so July and August ITc would be definitely much more than the sales,so where is the point of dues.Cam any professional explain,where I went wrong?
