IRS Publication 901
Definition of 'IRS Publication 901'
A document published by the Internal Revenue Service (IRS) that provides information on various tax treaties that exist between the United States and foreign governments, and whether those treaties reduce or eliminate U.S. income tax obligations for residents of those countries. Whether an income tax obligation is reduced or eliminated depends on the treaty provision with a given country. If a type of income is not addressed within a particular treaty, residents of that country will be taxed by the United States at the regular rate.
