Input tax credit entitlement for registrations, business reorganisations and exempt-to-taxable conversions clarified with payment rules. Availability of input tax credit is allowed for registrations obtained within prescribed timeframes and for persons newly liable, in respect of inputs, semi finished and finished goods in stock and capital goods immediately before the date liability arises or registration is granted, subject to prescribed percentage reductions for capital goods; a one year invoice based time limit applies. Transfers of unutilised electronic credit are permitted on specified business reorganisations where liabilities transfer, and conversion to composition or exemption requires payment equivalent to credit on stock and capital goods, after which remaining credit lapses.
