149. Hon’ble Members are aware that the modified one-by-six scheme, which I introduced in the Finance Act, 1998 to identify potential income-tax assessees and to bring them into the tax net, has paid rich dividends. I, therefore, propose to extend the one-by-six scheme to all urban areas in the country as defined by the 1991 Census. Changes arising out of the 2001 census will be incorporated subsequently.
