GSTR-2A non-reflection for FY 2018-19 operates as a scrutiny trigger rather than an automatic bar to input tax credit, but the claimant must prove substantive eligibility with objective, transaction-level evidence. A supplier certificate is evidentiary material, not a statutory deeming rule; unsupported B2C-reporting errors and residual IGST mismatches do not establish credit. IGST, CGST and SGST are distinct credit heads, so cross-head set-off requires legally permissible, transaction-level reconciliation. Additional evidence cannot fill evidentiary gaps or justify remand after adequate opportunities. Where wrongly availed credit was utilised, interest follows absent a demonstrated computational error, and non-fraud penalty applies where no separate basis for relief exists.
