If you are a U.S. citizen or resident, you can request assistance from the U.S. competent authority if you think that the actions of the United States, a treaty country, or both, cause or will cause a tax situation not intended by the treaty between the two countries. You should read any specific treaty articles, including the mutual agreement procedure article, that apply in your situation.

If your request provides a basis for competent authority assistance, the U.S. competent authority will consult with the treaty country competent authority on how to resolve the situation.

The U.S. competent authority cannot consider requests involving countries with which the United States does not have an applicable tax treaty.

It is important that you make your request for competent authority consideration as soon as you have been denied treaty benefits or the actions of both the United States and the foreign country have resulted in double taxation or will result in taxation not intended by the treaty.

In addition to a timely request for assistance, you should take the following measures to protect your right to the review of your case by the competent authorities.

1. File a timely protective claim for credit or refund of U.S. taxes on Form 1040X to preserve your right to a foreign tax credit if you do not qualify for the treaty benefit in question
2. Take appropriate action under the procedures of the foreign country to avoid the lapse or termination of your right of appeal under the foreign country's income tax law

Your request for competent authority consideration should be addressed to:

Director, International
Attn: Office of Tax Treaty
Internal Revenue Service
1111 Constitution Ave NW
Washington, DC 20224

The request should contain all essential items of information including the following items:

• The facts from which the issue arises
• The amounts of income and tax involved
• A description of the issue and identification of the relevant treaty provisions
• The respective positions taken by you and the foreign country
• Copies of any protests, briefs, or other pertinent documents

Additional details on the procedures for requesting competent authority assistance are included in  Revenue Procedure 2002-52 , which is in IR Bulletin 2002-31 (PDF).
