GST officers have busted a network of 23 entities involved in creation of fake invoices worth Rs 551 crore and passing inadmissible input tax credit worth Rs 91 crore. Based upon specific intelligence, the officers of the anti-evasion branch of Central Goods and Service Tax (CGST) Commissionerate, Delhi (West) have unearthed a case of availment/utilization and passing on of inadmissible input tax credit (ITC) through goods less invoices of about Rs 91 crore, the Finance Ministry said in a statement. The firms involved in this network are M/s Girdhar Enterprises, M/s Arun Sales, M/s Akshay Traders, M/s Shree Padmavati Enterprises and 19 others. These 23 firms were floated in order to generate goods-less invoices with an intent to pass on fraudulent ITC without paying actual GST to the government.
