The treasury taxes the bookmakers via the corporation tax, gross profit tax (GPT), amusement machine license duty (AMDL) and fixed odds betting terminals (FOBTs) to the government.

This raid will be bringing up data about the millions of pounds hampered by the bookers which the government supposes has been mined from gambling revenues, notably after when the 100-1 rank outsider Mon Mome made it to the Grand National earlier in April 2009.

According to an analyst, Ivor Jones, based at City broker, taxman would have a detailed overview of the profit from the rate of gross profit tax and they are likely to be taxing by FOBTs.

The financial analysts believe that the gross profit tax on net revenues might be increased to 20% from the present 15% rate.  Notably the 15% number has been around for quite a long time now. The treasury is for sure targeting casino gaming machines.

The FOBT casino machines have compensated and provided with enough financial assistance to big bookmakers when the traditional betting on the horses and dogs declined to burrows.  In 2008, Ladbrokes and William Hill earned more than £500 million from FOBTs.

The profit of the average betting shop has increased up to £2500 a week from the terminals in addition to £125,000 a year which are being paid as duty at an effective rate of less than 7%.

The bookmakers have been charged of using the slot machines with an intention to exploit gambling addicts the tax on the machines seems justified and appropriate per taxmen.
