I just registered a limited liability company for investing in the stockmarked. The company is a European register company. The company is registered as a Non-resident company and pays no tax on the profit. The company is registered in the north european country Denmark. It took me 3 weeks to have everything in place including a trading account with e-trade. I can recommend this type of company.
