This will be watered down in every way imaginable, escpecially the usual suspects like Malta with a straight up fraudluently advertised 30+ % corporate tax rate ,but they "refund" you everything but 5%, making it an effective 5% tax rate.

There is no way Malta will play along, it is a small state abusing all the EU benefits for nefarious purposes and never contributing anything useful.

This is just an example, there are many, many more more sophisticated schemes like that, Malta is just doing it openly.
