Doesn’t this deal have to meet the approval of the US Congress for the USA to even officially pass it?
Only Congress has the power to tax here in the USA, not the executive branch.
The agreement as it stands would have no impact here in the U.S. The minimum corporate tax rate they set is 15%. The U.S. currently has a flat corporate tax rate of 21% which is the lowest it’s been in decades (at least) and isn’t going to be getting cut any time soon.
That pesky Constitution requires treaties (I.e. agreements with other nations) to be approved by a 2/3 vote of the US Senate. Of course in recent years presidents have several times made agreements without securing Senate approval. Neither Congress nor the Judicial branch has acted to stop these international agreements which violate the Constitution.
The agreement would not be legally binding without a treaty. And actually, it wouldn’t be legally binding even with a treaty because all bills for the raising of taxes must originate in the House. A treaty ratified by the Senate doesn’t meet that standard.
Well, it used to be that way.
Roberts will deem it to be a "fine" ...
