Thanks for pointing Malta out as I understand this would require non dom tax residency there and this is something interesting for me to think about.
Country of Georgia is also a great cheap option, but i am thinking as W-8BEN-E form is asking for the name of organization that is the beneficial owner the Georgian company. This might effect the tax relationship with US (if its a non treaty jurisdiction that would be the holding company)?
In general I think I have to make some compromises and I prioritize shareholder privacy so Switzerland sounds like the most solid option. I am a little bit worried about depositing 22,000 USD as minimum share capital when registering as I have no experience working with nominee directors before. But I am not sure if there are any other similar options like Switzerland.
