Hie,
My maternal uncle deals with electronic good. He has not filled GST return from July 2017 To August 2018. neighter GSTR-1 nor GSTR 3B. My question is for filling GSTR -3B how much interest he has to pay and for GSTR-1 how much penalty he has to pay or he has to pay no penalty if he files before 31st Oct 2018
