Calcutta High Court Rules Clandestine Removal Cannot Rely Solely on Input-Output Ratios

The Calcutta High Court has delivered a significant ruling establishing that clandestine removal-the hidden, unrecorded dispatch of manufactured goods to evade taxes-cannot be legally presumed solely on the basis of discrepancies in input-output ratios. In indirect tax litigation, revenue authorities frequently compare the quantity of raw materials consumed against finished goods produced (input-output ratio) to allege tax evasion if variances appear.

Mathematical formulas and production ratios serve as analytical indicators rather than absolute proof of physical removal. Historically, tax departments often issued evasion demands relying primarily on theoretical consumption variances; the court's stance reinforces that structural assumptions cannot substitute for hard evidence. Indirect tax consultants and corporate legal teams should cite this Calcutta High Court precedent when defending clients against show-cause notices that allege clandestine removal based purely on mathematical production ratios.

Tax professionals must advise clients to maintain comprehensive, contemporaneous factory records and third-party corroborative evidence, such as transportation logs and financial transactions, to counter presumptive tax demands. Safeguard your manufacturing clients by auditing production records against this strict evidentiary standard.
