United States

United States has a relatively high top marginal personal income tax rate of 37% alongside a corporate income tax rate of 21%. The higher rates are typical of countries with extensive public services and social safety nets. Capital gains are subject to a 20% tax rate. Investors should factor this into their planning, particularly for significant asset disposals. United States taxes residents on their worldwide income, including foreign-sourced earnings. This means income from overseas employment, investments, and business activities is subject to domestic tax rates, though double taxation treaties may provide relief. United States permits dual citizenship, which provides flexibility for tax planning through establishing residency in a second jurisdiction without forfeiting existing citizenship rights.
