KOLKATA: Even a month after PM Narendra Modi sought to demonetise Rs 500 and Rs 1,000 notes, the country seems to be in turmoil with parties crying hoarse about the trouble of common man. However, demonetisation seems to have come as a windfall for some in West Bengal An investigation by the IT department has revealed that dormant Jan Dhan accounts are now flush with funds. Bengal now has second-highest deposits in the poor man’s accounts.Of 17 cases probed by the IT department for unexplained cash deposits in Jan Dhan accounts, two depositors have surrendered. The rest would now be tried under the Benami Transaction Act.“Persons who have surrendered to the IT department will be booked under the Income-Tax Act. But, evaders would be tried under the Benami Transaction Act. They will be under double-trouble. Their cash will be confiscated and they will be prosecuted. We will not touch the account holders,” said a senior official of the department. “People fail to understand that the unaccounted cash will not turn white by depositing in Jan Dhan accounts,” he added.While probing the Jan Dhan accounts in the state, the Income-Tax department has come across many innovative ways of tax evasion.“We have been noticing new trends every day. We had stumbled upon two cases in which we found Rs 10 lakhs and Rs 15 lakhs in two Jan Dhan accounts. Both of the holders are residents of Nadia district and are share croppers. During the course of investigation, the account holders produced sale deeds of some properties. The cash was from the sale, they testified. We made a valuation of the respective properties. The value did not even reach `1 lakh. A thorough investigation revealed that the depositor made the false deed and signed an agreement with the poor people for depositing the black money in their account,” the official added.In another strange case, the investigators found that bank has reversed the credit entries. “This anomaly has been found in more than 60 cases in a particular bank. So, we are ruling out the scope of clerical mistake in this case. We are now trying to understand the design of this economic offence ,” said an investigator.Since West Bengal lacks big industries and big businesses, the cash accumulation in Jan Dhan accounts show involvement of the political parties.
