Input tax adjustment requires payment of input-tax-equivalent for stock before switching to compounding; remaining electronic credits lapse. A registered taxable person switching from section 7 to the Compounding Scheme under section 8 must pay an amount equivalent to input tax credit on inputs held in stock and inputs in semi-finished or finished goods on the day immediately preceding the switch; that amount is to be calculated as per GAAP under section 16(13), and any remaining balance in the electronic credit ledger will lapse after payment.
