The only sure way to avoid taxes ultimately is using anonymous banking, always in offshore jurisdictions with lax regulation. Although it is an expensive and hard to come by option it is still out there, creative accountants and private bankers may refer you to banks with increased confidentiality which tell you that your information is only shared with senior management and no one else but as soon as the tax man comes knocking you can bet that the information is freely disclosed. The only other publicly acknowledged option is nominee banking which is flawed not to mention risky, and the ultimate owner is always a requirement.

I have found a few places that claim to offer anonymous banking, one company that would refer me to an appropriate bank however they required ID and another place that wanted 50% of whatever was deposited to the account!

I doubt we will find somewhere on the internet because banks can't advertise it otherwise no other bank would deal with them, but if anyone does know of anything - let me know!
