Denial of ITC

CA NAMRATA KAYARWAR (299 Points)

11 October 2023  
Supplier has filed its GSTR 3B of Feb 20 and Mar 20 on 02/11/2020 and 14/11/2020 respectively.
Dept issued intimation saying that 3B has been filed after 30 sep therefore ITC is not allowed to be claimed due to last date to claim was 30 sep has been lapsed.

Is this correct or is there any relief for the same as 2020 was a year in which pandemic was at its peak.
