Why overseas residence does not eliminate U.S. filing
U.S. citizens and resident aliens generally remain subject to U.S. federal income tax on worldwide income even when they live, work, or operate a business abroad. The first step is therefore to determine whether gross income reaches the filing threshold for the taxpayer’s filing status. Importantly, the IRS states that amounts excluded under the foreign earned income exclusion or foreign housing rules are still considered when determining whether a return is required.
Layer one: the income-tax return
A taxpayer abroad may file Form 1040 and claim the foreign earned income exclusion, the foreign tax credit, or both where permitted. The foreign earned income exclusion is not automatic: eligibility generally depends on meeting either the bona fide residence test or the physical presence test. Under the physical presence test, the taxpayer generally must be physically present in a foreign country or countries for at least 330 full days during a relevant 12-month period.
A taxpayer should maintain a travel calendar, employment agreement, housing records, and evidence of foreign residence. These records become especially important when travel between countries interrupts the 330-day calculation.
Layer two: foreign financial accounts
FBAR is separate from the income-tax return. A U.S. person generally must file FinCEN Form 114 when the aggregate value of foreign financial accounts exceeds $10,000 at any time during the calendar year. The rule can apply even when the accounts generate no taxable income. Account balances should therefore be monitored collectively, not one account at a time.
The taxpayer should also test Form 8938, which has different thresholds and definitions from FBAR. Filing one form does not automatically satisfy the other.
Layer three: foreign entities and trusts
Foreign trusts, foreign gifts, and ownership or other relationships involving foreign corporations may trigger Forms 3520, 3520-A, or 5471. These forms can carry significant penalties for late or incomplete filing. A taxpayer should map legal ownership, beneficial ownership, signature authority, contributions, distributions, and loans before preparing the return.
Action checklist
- Prepare a worldwide income schedule in U.S. dollars.
- Reconcile every foreign bank and investment account by calendar-year peak value.
- Count travel days using full-day rules, not approximate months.
- Review foreign trusts, pensions, companies, and gifts separately.
- Confirm each information return’s deadline and extension procedure.
The key insight is that expatriate compliance is not one filing decision. It is a coordinated review of income, accounts, and foreign structures.
