The period is 2019-20

Have  you file all returns  GSTR1  &  GSTR 3B  form  July  2017  to  Sept  2019 ?. 

Yes I have filed all GST returns till sep 2019

If all return filed already then last date for this quarter will be 31 January.

Taxable Persons who have opted to file Quarterly Return : The last date to file FORM GSTR-1 for Q3 ( OCT - DEC ) 2020 is "31.01.2020."

But the Government vide Notification No. 74/2019 - Central Tax dated 26.12.2019, has brought an AMNESTY SCHEME i.e. the Government has waived the Late Fess levied u/s 47 of the CGST Act 2017 for FORM GSTR-1 for the period " JULY 2017 to NOVEMBER 2019" if all the Statements are filed within 10.01.2020.
