Input tax credit entitlement on stock and capital goods when registration or tax status changes, subject to prescribed reductions and time limits. Availability of input tax credit is provided where a person registers within prescribed timeframes, where registration is granted under deferred provisions, where a person exits the composition scheme, or where an exempt supply becomes taxable; credit covers inputs, inputs contained in semi finished or finished goods held in stock and capital goods on the day immediately preceding the relevant change, subject to prescribed percentage reductions for capital goods. Credit is barred for supplies after the expiry of one year from invoice issue; unutilised electronic credit may transfer on business reorganisation; opting for composition or exemption triggers payment equivalent to eligible credit reduced by prescribed percentages, and disposal of capital goods requires reversal based on deemed value or percentage rules.
