Taras Khizhnyak, Senior Lawyer, BMS Law Firm, believes that the demand to supply the INN related information is quite logical. “First, this will ensure full identification of individuals and increase the overall system security, since it will make using nominee persons virtually impossible and exclude errors”, he said. Second, the lawyer reminded, all transactions performed by taxpayers are linked to their INN, that is why this experiment will facilitate further working of tax authorities.
