Input tax credit apportionment depends on direct nexus with exempt output; incidental by-products do not trigger reversal.

Section 17 of the Karnataka Value Added Tax Act, 2003 applies only where purchased inputs have a direct nexus with exempt output or are used in mixed taxable and exempt supplies, requiring apportionment of input tax. Where a dealer manufactures a taxable product and an exempt article emerges only as an incidental by-product, without any separate manufacturing activity directed to that by-product, the sale of that by-product does not trigger proportionate reversal of input tax credit. Full input tax deduction was therefore allowed on these facts, and the denial of credit was set aside.

Issues: Whether Section 17 of the Karnataka Value Added Tax Act, 2003 applies where an exempt by-product arises incidentally in the manufacture of a taxable product, so as to deny full input tax deduction.

Analysis: Input tax deduction under the Karnataka Value Added Tax Act, 2003 is restricted where purchases are attributable to the sale or manufacture of exempted goods, and partial rebate applies where a dealer's inputs are used for both taxable and exempt supplies. The statutory scheme in Sections 10, 11(a)(1), 17 and Rule 131 requires a direct nexus between the purchased inputs and the exempt output for apportionment to arise. Where the dealer's business is the manufacture of a taxable product and the exempt article emerges only as an incidental by-product, without any separate manufacturing activity directed to that by-product, the mere sale of the by-product does not attract the partial rebate regime.

Conclusion: Section 17 was held not to apply on these facts, and the assessee was entitled to full input tax deduction.

Final Conclusion: The revision was allowed and the denial of full input tax credit was set aside on the footing that incidental emergence and sale of an exempt by-product does not justify proportionate reversal where the inputs were used for producing the taxable product.

Ratio Decidendi: Partial rebate and input tax restriction provisions apply only when there is a direct nexus between the inputs and the exempt output or mixed use of inputs for taxable and exempt supplies; an incidental exempt by-product from the manufacture of a taxable commodity does not by itself require apportionment of input tax.
