Accidental American

An accidental American is a U.S. citizen living outside the United States who may not know they have U.S. citizenship or U.S. tax filing obligations. This often includes people born in the U.S. who left as children and people born abroad to a U.S. citizen parent.

Why it matters for U.S. expats

Accidental Americans are subject to the same U.S. tax and financial reporting rules as other U.S. citizens. Depending on their income and assets, they may need to report worldwide income, file annual U.S. tax returns, and disclose foreign financial accounts.

This does not necessarily mean that they’ll owe U.S. tax. The Foreign Tax Credit, Foreign Earned Income Exclusion, and other provisions can often reduce or eliminate double taxation.

Common questions

1. What is an accidental American, and what are the tax obligations?

An accidental American is someone who acquired U.S. citizenship, usually at birth, despite having little connection to the United States. They may need to file Form 1040, report worldwide income, and submit an FBAR or other international reporting forms.

2. How do accidental Americans become tax compliant?

Eligible accidental Americans may be able to catch up through the Streamlined Foreign Offshore Procedures. This involves filing three years of required tax returns, six years of required FBARs, and Form 14653 confirming that the previous failure to file was non-willful.

3. I was born in the U.S. but left as a child. Do I owe U.S. taxes?

You are a U.S. citizen if you were born in the United States, even if you left as a child. You may have U.S. filing obligations, but whether you owe tax depends on your income, credits, exclusions, and individual circumstances.
