Extended GST limitation requires disclosed prima facie material linking tax shortfall to fraud, wilful misstatement, or suppression.
Section 74 permits extended GST limitation only where available material supports a rational prima facie view that a tax shortfall, erroneous refund or wrongful credit arose by reason of fraud, wilful misstatement or suppression of facts to evade tax. Final proof is not required at initiation, but suspicion or bare statutory labels are insufficient. Prior scrutiny, audit, inspection or pre-notice communications may provide the factual foundation if actually communicated and linked to the notice. The notice and final order must preserve fair opportunity, disclose the material basis, and remain within the grounds stated.
