National Board of Revenue has initiated an investigation against the owners of the prominent business conglomerates Beximco, Bashundhara, Summit, Orion, and Nassa groups.

They are-- , Beximco Group's co-founder and vice-chairman Salman F Rahman, Bashundhara Group Chairman Ahmed Akbar Sobhan, Summit Group founder-chairman Aziz Khan, Orion Group chief Mohammad Obaidul Karim and Nasa Group chairperson Nazrul Islam Mazumder.

The Central Intelligence Cell (CIC) of the National Board of Revenue (NBR) has taken the move. NBR sources said that they are under scanner to dig out alleged tax evasion by the businessmen and their associate businesses .

As per section-200 of the Income Tax Law 2023, the NBR is empowered to seek bank-account information of a taxpayer against his Taxpayer Identification Number (TIN) if they suspect any tax evasion.

Banks and NBFIs are bound to provide the account information to the taxmen as per law. The tax law has a penal provision in case of non-cooperation by the bank officials in providing required information of bank-account transactions.

Recently -- following the fall of the Awami League government in a student-mass uprising -- tax zone-15 of the NBR issued bank-account search notices of Awami League Presidium member Sheikh Selim and business tycoon S. Alam's family members.
