The GST investigation wing has noted Rs 2,000 crore worth of tax evasion in two months and has revealed that only 1 percent of over 1.11 crore registered businesses pay 80 percent of the taxes.

Central Board of Indirect Taxes & Customs member and the Director General of Goods and Services Tax Intelligence John Joseph stated that like small businesses, big corporate and multinationals make mistakes while filling GST returns too.

"If you look at where the tax is coming from, it is less than 1 lakh people paying 80 per cent of the tax, one does not know what is happening in the system, it is an important thing to study," he said in an Associated Chambers of Commerce and Industry of India event.

"Government revenue is being taken away. We in a short period of 1-2 months have detected over Rs 2,000 crore evasion which could be only the tip of the ice berg," he added, assuring that the GST intelligence wing will boost its efforts regarding the matter in the days to come.
