Reconciling GSTR-2B: How to Maximize Input Tax Credit (ITC) and Prevent Vendor Defaults

The High Stakes of GSTR-2B Reconciliation

Under Section 16(2)(aa) of the CGST Act, taxpayers can only claim Input Tax Credit (ITC) if the invoice details have been uploaded by the supplier in their GSTR-1 and reflected in the buyer's auto-drafted GSTR-2B statement. Claiming unreflected ITC attracts severe scrutiny, 18% penal interest, and potential tax notices.

The Challenge of Manual Purchase Registers

Enterprise procurement teams deal with hundreds of vendor invoices monthly. Common discrepancies include:

• Suppliers filing under an incorrect GSTIN.
• Discrepancies in invoice numbering (e.g., dropping leading zeroes or prefixes).
• Suppliers classifying B2B transactions as B2C.
• Delayed filings where vendors submit GSTR-1 after the monthly cut-off date.
