Regarding reversal of ITC

Himanshu (Student CA Final ) (114 Points)

one of my client has invoices reflecting ITC but that party has not filed its GSTR 1 and 3 B for the periods in which purchases are made by my client ,

now the question is at the time of reconciliation gst portal is showing excess credit claimed by such amount

now whether client is liable to reverse itc or it can claim it as he has valid Invoices reflecting purchases and gst thereon...
