Income Tax department has activated the Aadhaar and net banking-based e-filling verification system for tax payers to file the first appeal before a tax officer, on similar lines of online ITR filing. In order to reduce the interface between taxman and the tax payer, the department has recently operationalized the maiden facility on its official e-filing portal. “One EVC can be used to validate one form of the assesse irrespective of the assessment year. The EVC will be stored against the assesse PAN along with other verification details. The EVC will be valid for 72 hours or as otherwise specified,” a notification in this regard said.
