Dear Hareesh,
There are various Forms and Returns in GST and all the Forms have different due dates. Some of the basic Forms are as follows:-
GSTR1 (for Taxpayers having turnover upto 1.5 Crore) on quarterly basis - Last day of Succeeding Month following the quarter
GSTR1 (for Taxpayers having turnover above 1.5 Crore) - 11th day of Succeeding Month
GSTR3B- 20th Day of Succeeding Month
GSTR4 - 30th April following the end of financial year
GST CMP 08- 18th of the Succeeding Month following the quarter.
GSTR5- 20th Day of Succeeding Month
GSTR6- 13th of Succeeding Month
GSTR7- 10th of Succeeding Month
GSTR8- 10th of Succeeding Month
GSTR9- 31st December of Next Year
GSTR9A- 31st December of Next Year
etc.
But it is to be noted that GST Council issues notifications time to time with regards to change in the aforesaid due dates for any particular month on the basis of prevailing situation in our country and its economy.
Now coming to the question of Chaitanya Ji, due dates of above mentioned returns for the month of Feb, 2020 are as follows:-
GSTR1 (for Taxpayers having turnover upto 1.5 Crore) on quarterly basis - 30th June 2020
GSTR1 (for Taxpayers having turnover above 1.5 Crore) - 30th June 2020
GSTR3B (for the taxpayers having turnover upto 1.5 cr) - 30th June 2020
GSTR3B (for the taxpayers having turnover upto 5 cr) - 29th June 2020
GSTR3B (for the taxpayers having turnover above 5 cr) - 4th April, 2020 (without Interest and Late Fee) and 24th June, 2020 (with Interest @ 9% but without Late Fee)
GST CMP 08- 7th July 2020
GSTR4- 15th July 2020
GSTR5- 20th Day of Succeeding Month
GSTR6- 13th of Succeeding Month
GSTR7- 30th June 2020
GSTR8- 30th June 2020
Hope that it's helpful 🙂
Thanks
