What tax loop holes. Or are you acctuatly talking about legal deductions and credits?
I think post #39 explains it pretty well.
They may not be doing anything illegal or unethical, but there are certain parts of the tax code that make no sense to me, like large companies that are able to shelter cash offshore. I understand that our corporate tax is too high, and that’s why they do it, so why don’t lawmakers lower the corporate tax so they will keep that money here? Maybe the big corporations like it that way and they give enough money to both Republicans and Democrats to keep it that way?
