vat itc

You should have taken it by filling Trans-1. But Trans-1 is closed now

Form TRAN-1 should be filed by every person having ITC on closing stock and migrated to GST form VAT, Service Tax, or Central Excise.

The balance of closing stock held by a business as on 1st July 2017 has to be disclosed in TRAN-1 to claim ITC on the old stock in the GST regime.

Last date for TRAN 1 is over so you can't file it now as it is not available. 

As per Order No. 4/2018 , the taxpayer who could not file Tran 1 due to technical fault of portal & whose cases have been recommended by council can file the same by 31/01/2019.(This notification already posted by Our CCI member Mr. Pankaj sir)
