Discrepancies between GSTR-2A/2B and GSTR-3B are usually caused by timing differences (when the supplier files their return), supplier reporting errors (wrong GSTIN or B2C classification), or legitimate exclusions (such as RCM, imports, or blocked credits). Businesses should prioritize reconciling with GSTR-2B monthly and maintain clear documentation for all deviations to prevent tax notices.
