TDS credit reconciliation: taxpayers must verify tax credit statements and request deductor corrections for discrepancies. Discrepancies between actual tax deducted at source and the TDS credit reflected in Form 26AS occur when a deductor fails to furnish correct TDS details or uses an incorrect PAN; taxpayers should reconcile Form 26AS with their records, and where discrepancy is due to the deductor, the deductor must file a TDS/TCS correction statement to rectify the entries so that correct TDS credit is reflected.
