Hi sir,

Ive also received notice for mismatch. Please advise how to reply for it.

GSTR-2A is auto-populated from your suppliers GSTR-1 filings and keeps updating as suppliers file or amend, so it can change month to month. GSTR-3B is what you actually declared and filed for ITC claimed. The mismatch usually happens because a supplier filed GSTR-1 after you already filed your 3B, or you claimed ITC in a different month than when it appeared in 2A.

The safest fix is to reconcile your purchase register with 2A before every 3B filing, and if you claimed excess ITC in a past period, reverse it in the current 3B with 18% annual interest to avoid a demand notice.
