The State of Karnataka v. M/s M.K. Agro Tech (P) Ltd.
Background
The respondent company manufactured sunflower oil by processing sunflower oil cake, a process that also yields a tax-exempt by-product called de-oiled cake, which it sold separately for substantial revenue (roughly 45% of sale value). The Karnataka tax authorities held that because part of the output (de-oiled cake) was exempt from VAT, the company was entitled only to a partial input-tax rebate under Section 17 of the KVAT Act, 2003 and Rule 131 of the KVAT Rules, 2005, not a full rebate. The Karnataka High Court disagreed, ruling the company was entitled to full input-tax deduction because the de-oiled cake was merely an unavoidable by-product, not a separately "manufactured" good, and the State appealed to the Supreme Court.
Decision Breakdown
The Supreme Court held that Section 17 turns on the "sale" of goods, taxable or exempt, not on whether the exempt item was separately "manufactured", and since de-oiled cake was a marketable commodity that was in fact sold by the company (constituting 88% of the material output), its sale triggered the partial-rebate provision regardless of being a mere by-product. The Court found the High Court had wrongly ignored the plain language of Section 17 and had failed to even consider sub-rule (3) of Rule 131, which specifically provides the formula for apportioning input tax between taxable and exempt sales where such tax is not directly attributable to one or the other. Since taxing statutes must be interpreted literally rather than purposively when the literal reading does not produce an absurd result, the Court set aside the High Court's judgment and held the company was entitled only to the partial input tax rebate (apportioned via the Rule 131 formula), not a full rebate.
Lesson Learnt
For VAT/input-tax purposes, what matters is whether an exempt by-product is actually sold in the market, not whether it was deliberately "manufactured", and a business earning substantial revenue from a tax-exempt by-product can only claim a proportionate, not a full, input tax credit on the raw material used.
