GSTR-2B Reconciliation: Step-by-Step Guide to Claiming Full ITC
ITC is only allowed when your supplier has reported the invoice. Here is how to match GSTR-2B with your purchase register every month.
Why 2B, not 2A
GSTR-2B is a static, auto-drafted ITC statement generated on the 14th of each month. Since 2022, Section 16(2)(aa) allows ITC only for invoices appearing in 2B.
Download the file
Log in to the GST portal → Returns → GSTR-2B → Download JSON or Excel for the period.
Match against purchases
Compare supplier GSTIN, invoice number, date, taxable value and tax. Categorise into: matched, in books but not in 2B (follow up with supplier), in 2B but not in books (missed bill), and value mismatches.
Take action
Claim ITC only for matched invoices. Chase suppliers for missing ones before their GSTR-1 deadline. Reverse ITC under Rule 37 if you have not paid the supplier within 180 days.
