Where are the funds from the Mansion and Casino Tax?

COLOMBO (News 1st) - Addressing a programme in Colombo today (June 14), former State Minister S. B. Dissanayake made a revelation. The former state minister spoke of the 'Mansion Tax' and 'Casino Tax'. He said: "During the 100 day government, they imposed something called the Mansion Tax. Then something called a Casino Tax. They took sums of 2 billion in one go. But this wasn't gazetted. A few in the United National Party showed this and said this won't be gazetted because if it does, it will be 2 billion. So instead they collected sums of 500 and 600 million." The auditor general states the country has lost Rs. 3.5 billion of the estimated income as stated in the budget, and he attributes this to the non-collection of the Casino Tax. Is this yet another massive fraud?
