Sorry Anupama I actually misread your query , yes You have to fill ITC 03 GST ITC-03 is a Form to file to pay an amount through the common portal, by way of debit in the electronic credit ledger or electronic cash ledger equivalent to credit availed in respect of of input held in stock .
So if there is not enough balance in ECL but the input on stock shown in ITC 03 is Higher then have to pay by Electronic cash Ledger.
rawat sir then won't it result in double payment of tax for same amount ie first by way of tax already paid to supplier and then again payment equal to value of itc taken ?
