The government's move to reduce corporate tax of non-listed companies is unlikely to bring any good result for the common people, rather the multi-national companies in the country would be the most beneficiaries, said economists.   "This is very much frustrating," Honorary Professor of Department of Economics of Dhaka University Abu Ahmed told UNB over telephone.   He said that these non-listed companies usually do not pay taxes properly and they usually hide income figures."These are mainly family based companies, there is no involvement of public interest."
