Monthly process

  1. Download GSTR-2B (available on the 14th) or view it in GSTR-2B Reco.
  2. Match with your purchase register by supplier GSTIN + invoice number + date + taxable value + tax.
  3. Sort into four buckets:
BucketAction
MatchedClaim ITC
In books, not in 2BDon't claim yet. Ask the supplier to upload in GSTR-1/IFF. Claim in the month it appears.
In 2B, not in booksCheck if you received it. If yes, book it. If not yours, reject it in IMS.
Value/rate/GSTIN mismatchAsk the supplier to amend, or claim only the lower matched amount

Invoice Management System (IMS)

Accept, reject or keep pending each supplier invoice on the portal before GSTR-2B is generated. Rejected invoices don't flow into your 2B.

Supplier filing problems

  • Supplier not filing GSTR-1: invoice missing in 2B → no ITC. Follow up in writing; hold payment.
  • Supplier filed GSTR-1 but not GSTR-3B: ITC must be reversed under Rule 37A if not filed by 30 September.
  • Cancelled supplier GSTIN: invoices after cancellation don't give ITC.

Mismatch notices

If ITC claimed in GSTR-3B exceeds GSTR-2B beyond the limit, you get DRC-01C. Reply with reasons or reverse the excess.
