Composition scheme: taxpayers who availed input tax credit must reverse equivalent credits when opting in, with remaining credit lapsing. Taxpayers who availed input tax credit and opt for the composition notification must pay, via debit to the electronic credit or cash ledger, an amount equivalent to input tax credit on inputs in stock, inputs in semi finished or finished goods in stock, and on capital goods, as if the supply attracted applicable input credit reversal provisions; any remaining input tax credit in the electronic credit ledger shall lapse.
