if not there are many countries that have no taxes on capital gains which you can use. You can set up an offshore company and the same agent should be able to get you the necessary documents for the company, bank account and IB account opening. Probably getting some kind of bank/utilities statements in the country of your choice if you want to open the account under your personal name is enough.in the usa. trading in a roth ira is tax free.Quote from MWycliff:
Where is the best place in the world to open a Interactive Brokers account to minimize tax. Since IB requires proof of residency in the country the account is opened, it will have to be a location where residency is easy to procure and also a place where IB account can be opened.
