Corporate Taxes

Corporations have to pay at least 15 % on their profits now, where they've been paying nothing. I don't understand that, because it feels to me like, if your books say you have profits, you have to pay taxes on them. And if they, if they somehow cook their books or use use whatever they use, to get the zero, then they're not profitable. It is quite possible for corporations to record i'm pretty sure that if we use the sortof typical tax dodge,. so that its profits pop up in ireland, which has a low corporate tax rate and not in the united states.
