K Venkatesh never thought the initial in his name would put him in a spot over filing his tax returns. When his PAN card could not be linked to his Aadhaar card, the Chennai-based banker consulted his accountant who discovered the problem: Venkatesh’s initial ‘K’ was expanded as Krishnaswamy, his father’s name, in the Aadhaar database. The system wouldn’t accept the ‘mismatch’, leaving Venkatesh at his wits’ end. Millions of people across the country could be facing the problem as the government insists on linking the two accounts by July 31, a prerequisite to filing tax returns. Activists are angry.”This is threatening to turn taxpayers into defaulters,” says Gopal Krishna of Citizens Forum for Civic Liberties, New Delhi.
