theodp writes "Microsoft CEO Steve Ballmer is threatening to move Microsoft employees offshore if Congress enacts President Obama's plans to curb tax avoidance by US corporations. 'It makes US jobs more expensive,' complained billionaire Ballmer. 'We're better off taking lots of people and moving them out of the US as opposed to keeping them inside the US.' According to 2006 reports, Microsoft transferred $16 billion in assets to secretive Dublin subsidiaries to shave billions off its US tax bill. 'Corporate tax is part of the overall advantage of doing business in Ireland,' acknowledged Ballmer in 2005. 'It would be disingenuous to say otherwise.'"
