Per the IRS Claiming Tax Treaty Benefits webpage:
If a tax treaty between the United States and your country provides an exemption from, or a reduced rate of, withholding for certain items of income, you should notify the payor of the income (the withholding agent) of your foreign status to claim the benefits of the treaty. Generally, you do this by filing Form W-8BEN, Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding or W-8BEN-E, Certificate of Status of Beneficial Owner for United States Tax Withholding and Reporting (Entities) or Form 8233, Exemption from Withholding on Compensation for Independent (& Certain Dependent) Personal Service of a Nonresident Alien Individual with the withholding agent.
Per IRS Publication 519 U.S. Tax Guide for Aliens, page 48:
If you claim treaty benefits that override or modify any provision of the Internal Revenue Code, and by claiming these benefits your tax is, or might be, reduced, you must attach a fully completed Form 8833 to your tax return. See Exceptions below for the situations where you are not required to file Form 8833.
You must file a U.S. tax return and Form 8833 if you claim the following treaty benefits.
These are the more common situations for which Form 8833 is required. For additional provisions, see the Form 8833 instructions.
To access Form 8833 Treaty-Based Return Position Disclosure Under Section 6114 or 7701(b) in the TaxAct program:
Per IRS Publication 901 U.S. Tax Treaties:
This publication will tell you whether a tax treaty between the United States and a particular country offers a reduced rate of, or possibly a complete exemption from, U.S. income tax for residents of that particular country.
CAUTION! You should use this publication only for quick reference. It is not a complete guide to all provisions of every income tax treaty.
Page 2:
Treaty provisions generally are reciprocal (apply to both treaty countries); therefore, a U.S. citizen or resident who receives income from a treaty country may refer to the tables in this publication to see if a tax treaty might affect the tax to be paid to that foreign country.
