Amendment of GSTR 4

Which assessment year

FY 2019-20

Composition person is liable to file CMP-08 quarterly and you can disclose the turnover for jan to March in next quarter. Interest will be levied.

Under section 10 you have to file CMP 8 & you have to pay interest for the belated payment of tax

@ Gayathri Ji
As per Your Query you have filed GSTR 4 for Jan+March QTR. , but the GSTR 4 can be filed for whole Fy .
As per Rule 62 of CGST act , For Qtly return Form CMP08 is applicable & for annually for Fy GSTR 4 need to be furnished.

Note : You can add the missed sale in your subsequent QTR return , you cannot amend the already filed return.
