US Expats Still Face Tax and Reporting Duties Even When No Tax Is Owed, CNBC Reports

Americans who move abroad are not automatically exempt from U.S. tax and financial reporting requirements, according to a report from CNBC published Sept. 16, 2026. The report notes that many young expatriates are unaware that U.S. citizenship-based taxation means they may still need to file with U.S. authorities even while living and earning income overseas.

Under the U.S. tax system, citizens and permanent residents are generally required to report worldwide income to the Internal Revenue Service regardless of where they reside, CNBC reported. This obligation can persist even in cases where expatriates ultimately owe no U.S. income tax, due to provisions such as the Foreign Earned Income Exclusion and foreign tax credits that can offset or eliminate a tax bill.

The report also points to separate reporting requirements tied to foreign financial accounts. Individuals with foreign bank or investment accounts exceeding certain thresholds may be required to file a Report of Foreign Bank and Financial Accounts, commonly known as an FBAR, with the U.S. Treasury Department's Financial Crimes Enforcement Network. Failure to file these disclosures, even when no tax is owed, can carry penalties, according to the report.

CNBC's report suggests that younger Americans living overseas, some of whom may have moved abroad for work, study or lifestyle reasons, are particularly likely to be unfamiliar with these ongoing obligations, since income taxes in many other countries are generally tied to residency rather than citizenship.

The report underscores that maintaining U.S. citizenship while living abroad carries continuing compliance responsibilities distinct from those faced by citizens of most other countries, who typically owe tax reporting obligations only to the country in which they reside.
