What a dishonest graphic! The Double Irish doesn't affect US taxes. And Apple doesn't pay 0.7%.
They are sending their IP, they are setting up an Irish sub, they are deduction the cost of the IP, They are setting up an international tax haven Sub, they are stashing the cash in the EU. Point is that it is not just about Ireland giving them a tax break.
Also, Once you take advantage of the off shore loop hole and/or keep the cash in foreign accounts it affects US taxes. Irish or no Irish tax break.
Why do you think they selling 30 year bonds? To raise cash? Apple has tons of cash. But if they bring home the cash this all falls apart - so they rather take on debt at 3.5% yield and not pay the US tax on repatriation.
