FATCA related FAQs involving U.S. passport or other evidence of U.S. citizenship . See KB2601 for other FATCA related FAQ topics.

Q1: I received a notification saying a review of my file indicated I am a U.S. citizen. I am being asked to complete IRS Form W-9 and provide a U.S. Social Security Number. I am not a U.S. citizen. What should I do?
 

A1: In most cases you received this message because our review of your file indicated you had U.S. citizenship or a U.S. place of birth, which likely infers automatic U.S. citizenship and U.S. taxpayer status even if you do not live in the U.S. or hold a U.S. passport. US citizens are required to provide us with IRS Form W-9 and a valid social security number. Nevertheless, we may accept IRS Form W-8 from you to establish your status as a non-U.S. taxpayer if you provide us with a copy of your Certificate of Loss of Nationality of the United States (Form DS-4083) and a copy of your passport evidencing citizenship in another country. Alternatively, you may provide us with a written explanation of why you are not a U.S. citizen (for instance, you were born in the United States to parents who were fully-accredited foreign diplomats). We may request further information from you depending on the explanation provided. 
 

Q2: I gave up my U.S. citizenship. What should I do?
 

A2: Please provide us with a copy of your Certificate of Loss of Nationality of the United States (Form DS-4083) and a copy of your passport from another country.
