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