In introducing his bill MP Matthew Hancock wanted to level the playing field since many of the jurisdictions on the white list are also tax havens or have reduced tax requirements. He wants all online gaming operators to have a UK Gambling Commission Licence so that they will all be subject to the UK tax system if they are to be able to offer online gaming to British players. At the moment UK based online gaming companies pay taxes while many offshore operators pay very little or none. (See article: Changes to the UK Gambling Act Could Have a Negative Effect on Online Gaming).
Opponents of the bill introduced by Hancock fear that if the overseas online gaming operators were to be licensed and had to pay UK taxes that the cost of using their services would rise and so British players would look online for unlicensed and unregulated gambling sites offering better deals. This would bring about all of the problems linked to unregulated gambling.
The bill will be debated again in Parliament next month. As it stands the regulations governing online gaming in the United Kingdom appear to give an unfair advantage to the operators licensed outside the UK as they are not subject to the same tax system as online gaming operators based in the UK and holding a UK Gambling Commission licence.
