Further dangling the stick, government has warned that cash deposits above 2 lakh 50 thousand rupees threshold under the 50-day window could attract tax plus a 200 per cent penalty in case of income mismatch. <br/><br/>Revenue Secretary Hashmukh Adhia said last night that the ministry would be getting reports of all cash deposited during the period of November 10 to December 30, 2016, above a threshold of 2.5 lakh rupees in every account. He said, the tax department would do matching of this with income returns filed by the depositors. And suitable action may follow.<br/><br/>Any mismatch with income declared by the account holder will be treated as a case of tax evasion. The government has allowed citizens to deposit in their bank accounts old currency of 500 rupees and 1,000 rupee denominations, which had been declared invalid.
