Input tax credit entitlement for stock and capital goods requires prescribed adjustments and ledger payment when status changes. Input tax credit is available for inputs and inputs contained in stock and finished or semi-finished goods held immediately before the date a person becomes liable or is granted registration, and when exempt supplies become taxable, subject to prescribed reductions for capital goods. Credit claims lapse after one year from the invoice date. Unutilised credit may be transferred on change in business constitution. Where a registrant opts into or out of certain schemes or supplies become exempt, an amount equivalent to attributable credit for stock and capital goods (reduced as prescribed) must be paid via electronic ledgers; for supply of capital goods previously claimed, payment equals adjusted credit or tax on transaction value, whichever is higher.
