The United States has income tax treaties (or conventions) with a number of foreign countries under which residents (sometimes limited to citizens) of those countries are taxed at a reduced rate or are exempt from U.S. income taxes on certain income received from within the United States.
Income that is exempt under a treaty is not subject to withholding at source under the statutory rules discussed in this publication. taxmap/pubs/p515-011.htm#en_us_publink1000225128taxmap/pubs/p515-011.htm#en_us_publink1000225129
