The Anti-Corruption Commission has filed 50 cases in last one year since July 2011 against 60 officials of the National Board of Revenue in connection with their alleged corruption.
The commission is also investigating into 100 more allegations, a commission official said.
Preliminary inquiries of the commission have found some officials of different departments of NBR, including Revenue, Customs and Value Added Tax, being involved in corruption and owned wealth disproportionate to their legitimate sources of income.
The commission formed a three-member committee led by its deputy director Abdullah Al-Jahid on March 8, 2011 to probe graft allegations in the revenue board.
About 32 lakh people have Taxpayer Identification Number in the country, but only nine lakh were paying tax regularly, the official said, observing that the rest 23 lakh, who do not pay tax regularly, somehow had to manage NBR officials.
The officials include suspended assistant revenue commissioner Anisur Rahman Talukder, Dhaka south circle superintendent Shahadat Hossain, custom inspectors Ataur Rahman Akand, Mamunul Haque Chowdhury, Eyadur Rahman Molla and Sadequr Rahman, suspended custom inspector Mojibur Rahman Sarkar, suspended principal appraiser Mahfuzur Rahman, assistant revenue officer Abul Kasem, former NBR member M Azizur Rahman, former commissioner Nurul Islam, former deputy revenue commissioner Abdur Shakur, former customs super Sheikh Akram Hossain, former appraiser Syed Sobhan and former inspectors Abdul Momin, Azizul Haque Molla, Khandaker Masudur Rahman, Mosharraf Hossain and Showkat Ali.
ACC also found some tax lawyers were connected with corruption and filed cases against Mustafa Khan, Mojibur Rahman, M Harun-Ar-Rashid, SM Alam, SM Nuruzzman, Sekih Aliur Islam and Ghulam Rahman, he said.
The ACC official said that the commission has already approved some charge-sheets in some cases and the committee would submit some primary reports to the commission after Eid-Ul-Fitr.
