What is Form 6166?

Most of the U.S.A. Apostille treaty partners require the IRS to issue a proof that the person claiming the benefits specified in the international agreement is a resident of the United States for federal tax purposes. The IRS provides this residency certification by issuing Form 6166 also known as a letter of U.S. residency certification.

Also, Form 6166 may be used as a proof of U.S. tax residency status for purposes of obtaining an exemption from a VAT imposed by a foreign country (to avoid double taxation). In connection with a VAT request the United States can certify only to certain matters in relation to your U.S. federal income tax status and not that you meet any other requirements for a VAT exemption in a foreign country.

The Internal Revenue Service (IRS) procedure for requesting a certificate of residency (Form 6166) from the Philadelphia Accounts Management Center is the submission of Form 8802, Application for United States Residency Certification. Use of the Form 8802 is compulsory.

The letter (Form 6166) is made on U.S. Department of Treasury stationary and confirms that an individual or company is a United States resident for purposes of the income tax regulations of the United States for the fiscal year indicated on the Form. You may use this form to claim income tax treaty benefits and certain other tax benefits in foreign countries, the parties to the International Treaty.
