Singapore and Estonia both seem to be doing things right. Singapore (unlike Estonia) also has a fairly long tradition of being a great place for foreigners to incorporate, a well established and stable legal regime, sane taxation, etc. Estonia also looks pretty good, but they haven't been around as long so the odds of them making trouble for you in the future are probably higher than Singapore. A Singapore corp will require you to pay taxes once on corporate income. After that it's simple - make distributions to yourself and pay only local taxes. It's as if Singapore asked economists what the most efficient way to run a society is and then actually did that. A US business entity is probably a very bad idea due to things like taxation on global income and just general US insanity.
