S. 147:Reassessment -Bogus purchases – Even the assessment which is completed u/s 143(1) cannot be reopened without proper ‘reason to believe’. If the reasons state that the information received from the VAT Dept that the assessee entered into bogus purchases “needed deep verification”, it means the AO is reopening for doing a ‘fishing or roving inquiry’ without proper reason to believe, which is not permissible.[ S.143(1), 148 ]
