Afaik the tax will just be for Londoners.
See this:
Londoners could be facing a £160 rise in council tax over seven years, should the British capital wins its bid to host the 2012 Olympics.
The tax increase is one of the methods of fund raising to pay for a London Olympics included in The Horserace Betting and Olympic Lottery Bill, and would raise £625 million towards the overall cost from public funds of £2.4 billion.
The money earmarked for the Games also includes the profits from a new lottery, which will be launched if the bid is successful, and could raise up to £750 million.
"Should we win the right to host the Olympics the Bill paves the way to introduce an Olympic Lottery straight away," said Culture Secretary Tessa Jowell.
"By making this possible we are showing our commitment to do everything possible to bring the Olympics to London in 2012.
"We hope that a dedicated Olympic Lottery could raise up to £750 million to help fund the 2012 Games, which would bring benefits across the UK including regeneration and increased investment.
"It also has the potential, as part of a wider strategy for growth, to help re-invigorate the entire Lottery."

Personally, I think the £2.4 billion will be well spent if the long-term benefits are factored in. There is far too little emphasis on sport in this country, school sport having been in decline for many years and it's about time something was done about it. And East London is the ideal centrepiece for the event.
