AFAIK this misses the point. If a EU citizen is contracted by a US company, but living in the EU they are not subject to US income tax at all, but only to their own state's - and also this might not be legal if the US corp has a EU subsidiary. (If they live in the US they are taxed by the US first and their home country second, but taxes paid in the US are being deducted from the taxes they have to pay in their home country. And, if they are contracted with a EU based subsidiary then they are taxed in the EU only, obviously.)
