Tax Treaties

The United States has tax treaties with a number of foreign countries; these treaties generally provide that residents of foreign countries are taxed at a reduced rate, or are exempt from U.S. taxes on certain item of income they receive from U.S. sources. For more information on treaty research, see the treaties section of the Ross-Blakley Law Library research guide on International and Foreign Law.
