The Mumbai bench of the Income Tax Appellate Tribunal (ITAT) has sought further investigation into one of the cases linked to HSBC’s Geneva branch involving a US-based NRI, Rahul Rajnikant Parikh. A list of people of Indian origin having bank accounts in Geneva was handed to India by France in 2011. More than 1,000 deposit holders of Indian origin in HSBC’s Geneva branch are under the scanner of tax and other investigating agencies for holding black money.
