Financial Tribune - To fight rampant tax evasion and fraud, the Iranian National Tax Administration will henceforth focus on the minority taxpayers who indeed are liable for the majority of unpaid taxes, head of INTA said.

Speaking on state TV late on Saturday, Omid Ali Parsa said �Estimates suggest there are about 400-450 trillion rials ($2.2 billion-$2.5 billion) in unpaid taxes�.

The senior official said a small group of tax dodgers account for a large portion of unpaid taxes.

�INTA is concentrating on almost 4,000 people who are wealthy and have very high incomes but pay less tax,� Fars News Agency quoted him as saying.
