Where any registered person who has availed of input tax credit opts to pay tax under section 10, i.e, Composition Taxation or, where the goods or services or both supplied by him become wholly exempt, he shall pay an amount, by way of debit in the electronic credit ledger or electronic cash ledger, equivalent to the credit of input tax in respect of inputs held in stock and inputs contained in semi-finished or finished goods held in stock and on capital goods, reduced by such percentage points as may be prescribed, on the day immediately preceding the date of exercising of such option or, as the case may be, the date of such exemption:
Provided that after payment of such amount, the balance of input tax credit, if any, lying in his electronic credit ledger shall lapse.
In case of supply of capital goods or plant and machinery, on which input tax credit has been taken, the registered person shall pay an amount equal to the input tax credit taken on the said capital goods or plant and machinery reduced by such percentage points as may be prescribed or the tax on the transaction value of such capital goods or plant and machinery determined under section 15, whichever is higher:
Provided that where refractory bricks, moulds and dies, jigs and fixtures are supplied as scrap, the taxable person may pay tax on the transaction value of such goods determined under section 15.
