What this result includes

Compare the same GSTIN, period and tax heads on the same basis. Figures are control totals, not an invoice-level reconciliation or an ITC eligibility determination.

GSTR-2B appearance does not by itself establish eligibility. Review invoices, restrictions, reversals, RCM and the applicable return / IMS position before claiming ITC.

Timing, amendments, credit notes, advances and omitted invoices can explain a difference. Even matched totals can conceal offsetting errors; retain the underlying reconciliation.
