Why monthly GSTR-2B reconciliation protects your input tax credit

Every month, your suppliers report their sales to you in their own GST returns. Those details flow into your GSTR-2B — an auto-drafted statement of the input tax credit (ITC) available to you for that period.

Since January 2022, the credit you claim in GSTR-3B is expected to match what appears in your GSTR-2B. If a supplier forgets to file, files late or reports a wrong GSTIN, that credit will not appear — even though you paid the tax on the invoice.

What goes wrong without reconciliation

• Credit is claimed but not in GSTR-2B — this can lead to mismatch notices, reversal of credit and interest.
• Credit is in GSTR-2B but missed in your books — you simply pay more tax than you need to.
• Supplier errors go unnoticed — by the time they surface, the time limit to correct them may have passed.

What a monthly reconciliation involves

1. Download GSTR-2B for the month.
2. Match it invoice-by-invoice with the purchase register in your books.
3. List the differences — missing invoices, value differences, wrong GSTINs.
4. Follow up with the suppliers concerned before the next return.
5. Claim only eligible, matched credit in GSTR-3B.

A 30-minute reconciliation every month is far cheaper than a notice, a reversal and interest a year later.
