According to the 1994 article: Bahamas; Ireland; Hong Kong; Singapore; Belize; the Cayman Islands; Israel.
Israel?
As much as I respect the Israelis, I will pay the US taxes rather than be blown up.
Hong Kong?
I have no desire to kiss the butts of the ChiComs.
Bahamas? Belize?
Nope.
Ireland?
Might not be bad but what are the current tax rates?
