Respected Sir, I wrongly filled Quarterly GSTR-3B Jan-21 To March-21 Rs. 82408.80 as CGST instead of 41204.00 & Same amt. as SGST. I did not file GSTR-1 so what will be the correction procedure. Please guide us.
There is no option to amend GSTR-3B, however you can reduce the amount from next month's return. As far as GSTR-1 is concerned enter correct amount in GSTR-1
