Sir — Without standing on false prestige, Union Finance Minister Arun Jaitely has done well to roll back a Budget proposal to tax 60 per cent of the Employees’ Provident Fund amount. The Union Government must explore the possibilities of mopping up tax revenue from sources where people conceal their income to evade tax. Taxing on terminal benefits is unfair. Tax base should be expanded without further burdening the existing class of taxpayers, who are mostly Government employees.
