Of course he did not pay taxes. Why would he pay taxes in a tax free country?
No as a whole I bet he paid about 1.5% taxes.
So say he has 90% of assests in tax free places. That means he paid 1.5% taxes over all. (assuming 15% USA rate for mega rich)
You will also remember that he transfered, with no USA inheritance taxes to his kids. $250 million.
(special stock exemption)
From taxation law site. Or any other source you look at. same thing. ZERO TAXES on the mega rich.
