Itc time limit

30th September and date of annual return which is earlier.

Agree with Mr. Apurba

As per the Provision of Section 16(4) of the CGST Act 2017, Input Tax Credit ( ITC ) of a particular Financial Year can be claimed within the DUE DATE of filing Return for the month of September following the FY ( i.e. 20th October ) or the DATE of filing Annual Return, whichever is "earlier".

For example, the last date to claim ITC for FY 2019-20 was 20th October 2020 i.e. the due date of filing Return ( FORM GSTR-3B ) for the month of September 2020 ( being it earlier than the date of filing FORM GSTR-9 ).
