Several jewellers have been put under scrutiny by the income tax department in cases of alleged large and disproportionate cash deposits during the demonetisation period (November 9-December 30, 2016). In some cases, some of these jewellers have been found to have deposited nearly 1,000 times as much cash during this period compared to the year-ago period, sources said. Apart from large cash deposit not commensurate with income profile, the department scrutinised cases where taxpayers reported massive increase in unsecured loans during the year or loans fully paid involving huge amounts, the sources said. These jewellers under scrutiny have also not shown the cash so deposited in their return of income for the AY2017-18, which triggered the data analytics system of the department. “A Gujarat-based jeweller was found to have deposited cash of over Rs 4 crore during demonetisation against just over Rs 40,000 a year ago,” a tax official privy to the scrutiny said.
