ITC CLAIMED DIFFERENCE ADJUSTMENT PROCEDURE IN GST RETURNS AND BOOKS

Case1:

If you have claimed the correct GST amount in your GSTR 3B and short GST ITC is reflecting in your GSTR 2B/2A then no need to make any reversal now. 

Please ensure that you have a copy of all the invoices against whom extra ITC has been taken. Further, also take party confirmation whether they have filed their GST returns or not and have reported the said ITC. 

Case2:

ITC as per GSTR 2B/2A is more than ITC claimed in GSTR 3B. Suppose if the ITC was related to FY 2020-21 then the last date to claim the remaining ITC was 20th October 2021 which has already passed. The unclaimed ITC has become time-barred now.
