Finance Minister Arun Jaitley said investigations into information, put into public domain by the ICIJ, pertaining to about 700 Indian persons allegedly linked to offshore entities based in no tax or low tax jurisdiction, have led to detection of more than Rs 11,010 crore of credits in undisclosed foreign accounts.
"72 prosecution complaints in 31 such cases have been filed before the criminal courts," he informed the Lok Sabha.
The government constituted a multi-agency group (MAG) in April 2016 for facilitation co-ordinated and speedy investigation in the cases of Indian persons allegedly having undisclosed foreign assets and whose names were reportedly included in Panama papers leak.
He further said that information on 628 Indian persons holding bank accounts in HSBC bank in Switzerland was received from the government of France under the Double Taxation Avoidance Convention (DTAC) between India and France.
"As a result of systematic investigation in these cases, undisclosed income of about Rs 8,437 crore was brought to tax till May 2017.
He noted however that the information received under the tax treaties can be used for tax purposes and its disclosure is governed by the confidentiality provisions of such treaties.
Replying to a query, whether the government has made any assessment of black money stashed by Indians in foreign countries, Mr Jaitley said there is no official estimation of that.
However, he said, the government had commissioned a study on estimation of unaccounted income and wealth inside and outside the country to be conducted by NIPFP, NIFM and NCAER.
"The reports of these institutions and the government's response on the findings in the reports would be placed before the Standing Committee on Finance shortly," he added.
