How ITC Flows — GSTR-1 to GSTR-2B to GSTR-3B
ITC in GST follows a document trail: your supplier files GSTR-1 (outward supplies) → the data auto-populates in your GSTR-2B (auto-drafted ITC statement, generated monthly on the 14th) → you claim ITC in GSTR-3B (Table 4) based on GSTR-2B. If your supplier does not file GSTR-1, the invoice will not appear in GSTR-2B, and you cannot claim ITC — even if you hold the physical invoice and have paid the GST.
GSTR-2B is static (does not change after generation). GSTR-2A is dynamic and updates in real time. For ITC claims, GSTR-2B is the controlling document as per Rule 36(4).
