Could you say again what you want? I am not following you.
For context, most of the world uses a “source” standard of income. If you earned X dollars in country Y you pay Country Y’s tax on those X dollars. America (and a few other small countries) uses a domicile test – If you are a American corporation you will pay American taxes on that income no matter where it was earned. (This at times has led to a tax rate over 100% - so America put in a lot of fudges, exemptions, etc. which makes our tax code very inefficient.)
So, to you – should small companies (under X people) pay corporate tax and not big ones? Why would they move to America if they still had to pay profit on their overseas operations? (I am assuming that if a company were operating oversea that their market would remain there while they were physically here?)
(FYI, I am all for dropping the corporate tax rate to near zero – assuming is is coupled with the closer of some loopholes. And, I think part of America’s future is being an international hub, where bright people from around the world come and mix to create new things – so nix the non-citizen part – welcome almost everybody.)
