The IRB sent a letter to Najib just over a week ago stating the extra tax he has to pay, sources say.
KUALA LUMPUR (Apr 1): The Inland Revenue Board (IRB) has slapped Datuk Seri Najib Razak with an extra tax bill of around RM1.5 billion ($498 million) for 2011-2017.
Sources say the amount is on top of what the former prime minister had paid based on his declared income for that seven years.
