I thought the way that one Apple subsidiary avoided taxes was pretty clever. The USA taxes corporations by their headquarters location, and Ireland taxes companies by their physical presence. So apple created a headquarters in Ireland, but did physical business in the USA. So the USA didn't tax it because it's HQ was in Ireland, and Ireland didn't tax it because it's physical presence was in the USA. So that subsidiary paid absolutely zero taxes, they didn't even file. It saved Apple a good 5 billion dollars.
