What are the compliances from ITC reversal point of view that need to be made by a person opting for composition levy?

The registered person opting to pay tax under composition scheme is required to pay an amount equal to the input tax credit in respect of inputs held in stock and inputs conatined in semi-finished or finished goods held in stock on the day immediately preceding the date of exercise of option. The ITC on inputs shall be calculated proportionately on the basis of corresponding invoices on which credit had been availed by the registered taxable person on such inputs.
In respect of capital goods held in stock on the day immediately preceding the date of exercise of option, the input tax credit involved in the remaining useful life in months shall be computed on pro-rata basis, taking the useful life as 5 years. Assume capital goods have been in use for 4 years, 6 months and 15 days. The useful remaining life in months will be 5 months ignoring the part of the month. If ITC on such capital goods is taken as C, ITC attributable to the remaining useful life will be C multiplied by 5/60. This would be the amount payable on capital goods.
The ITC amount shall be determined separately for integrated tax, central tax and state tax/Union territory tax. The payment can be made by debiting electronic credit ledger, if there is sufficient balance in the said ledger, or by debiting electronic cash ledger.The balance , if any in the electronic credit ledger would lapse.
Such persons also have to furnish the statement in FORM GST ITC-03 which is a declaration for intimation of ITC reversal/payment of tax on inputs held in stock, inputs contained in semi-finished and finished goods held in stock and capital goods under Section 18(4) of the CGST Act, 2017 within a period of sixty days from the commencement of the relevant financial year.
