Why your input tax credit goes missing — and how 2B reconciliation fixes it

By Abhishek Kumar · B.Com (Accounting & Finance)May 28, 2026 6 min read
Input tax credit goes missing when your purchase records don't match GSTR-2B — the auto-drafted statement of credit your suppliers have actually reported. A monthly reconciliation between your books and 2B before filing GSTR-3B is how you claim every rupee you're entitled to.

Why credit disappears

  • A supplier didn't file their GSTR-1, so the invoice isn't in your 2B.
  • Wrong GSTIN, invoice number or amount creates a mismatch.
  • Invoices land in the next period, shifting the credit month.

A simple monthly routine

Download your GSTR-2B, match it line-by-line against your purchase register, and split the result into three buckets: matched (claim it), missing in 2B (follow up with the supplier), and missing in books (record it). Only claim credit that appears in 2B to stay compliant.

Chase the gaps early

The earlier you flag a supplier whose invoice isn't reflected, the more likely they fix it before the credit is lost. Build this into your month-end close rather than doing it at the last minute before GSTR-3B.
