Yes Late filing fee would be 200/- per day (cgst-100, sgst-100)

Hi, is there any circular available for late..?

For late filing

Late filing attracts penalty called late fee. The late fee is Rs. 100 per day per Act. So it is 100 under CGST & 100 under SGST. Total will be Rs. 200/day. The maximum is Rs. 5,000. There is no late fee on IGST in case of delayed filing. 

Along with late fee, interest has to be paid at 18% per annum. It has to be calculated by the taxpayer on the tax to be paid. The time period will be from the next day of filing to the date of payment.

For not filing

If you don’t file any GST return then subsequent returns cannot be filed. For example, if GSTR-2 return of August is not filed then the next return GSTR-3 and subsequent returns of September cannot be filed.  Hence, late filing of GST return will have a cascading effect leading to heavy fines and penalty
