Do you really think that BMW, Daimler, Rolls Royce, Honda, Toyota and everyone else didn't pay any taxes for the business they did here? And while they made huge untaxed profits in the US they built factories here so they could be taxed on everything?
Accenture pays taxes on all profits made on work in the US. If it was not so, then my off-shore company would not be paying taxes on every dollar that is earned here.
Out of curiosity, does your off-shore company sell goods or offer services, or both?
