Input tax credit availability: rules for claiming, transferring or repaying credit on stock and capital goods under GST. Persons registering after becoming liable, or on grant of delayed registration, may claim input tax credit for inputs and inputs contained in stock immediately before liability or registration. Where liability status changes from composition to regular or exempt supplies become taxable, credit for stock and capital goods held immediately before the change is allowable subject to prescribed percentage reductions. Claims must be made within one year of invoice issue and calculated as prescribed. Transfers of unutilised electronic credit are permitted on change of business constitution with specific liability transfer provisions. Opting into composition or exemption requires payment from electronic ledgers equal to attributable credit, after which remaining credit lapses.
