The US and UK Income Tax Treaty is a deliberate document aimed to eliminate such abuses as the double taxation of companies and citizens by agreeing such things between the two countries (Kroeker and Ainsworth). The US and UK Income Tax Treaty outlines how the income of the residents of one of the two countries is going to be recognized in the other. Moreover, the treaty guarantees that people and businesses never need to pay the income tax for the same income twice. That has to mean residents of one of the two countries. To be more specific, the articles of the treaty underline numerous sources of income, including dividends, interest, and royalties, which is an important element for the understanding of tax matters for expatriates and cross-border investors.
