That doesn't apply to your federal but state taxes. It's basically the same as Ireland, certain states are shelters... http://pennbpc.org/time-close-loopholes-delaware-loophole http://pennbpc.org/time-close-loopholes-delaware-loophole Here’s how it works: A large multi-state corporation creates a shell company in a tax-haven state like Delaware. The subsidiary has no employees and is often nothing more than a post office box. The corporation then uses accounting gimmicks to funnel profits through the shell company, leaving no apparent income on the books in Pennsylvania. It may be legal, but it isn’t fair.
