Taxes & Finance
Navigate US tax obligations abroad, FBAR, FATCA, and international banking.
The United States taxes its citizens and resident aliens on their worldwide income regardless of where they live, so moving abroad does not, by itself, end your U.S. federal filing obligation. The IRS sets the same gross-income filing thresholds for Americans overseas as for those at home, and the core guide for this population is IRS Publication 54, 'Tax Guide for U.S. Citizens and Resident Aliens Abroad,' which covers the foreign earned income exclusion, the foreign housing exclusion, and the qualifying residence tests. Taxpayers living outside the U.S. and Puerto Rico on the regular due date receive an automatic 2-month extension to file (to June 15 for calendar-year filers), though any tax owed still accrues interest from the original April deadline. Beyond the income tax return (Form 1040), Americans abroad face separate information-reporting regimes. Foreign financial accounts whose aggregate value exceeds $10,000 at any point in the year must be reported on FinCEN Form 114 (the FBAR), filed electronically with the Treasury's Financial Crimes Enforcement Network rather than with the IRS. Under FATCA, individuals holding 'specified foreign financial assets' above threshold amounts must additionally file Form 8938 with their tax return. These filings are reporting requirements, not separate taxes, but carry significant penalties for noncompliance. To mitigate double taxation, U.S. law offers the Foreign Earned Income Exclusion (Form 2555) and the Foreign Tax Credit (Form 1116, detailed in Publication 514), and bilateral income-tax treaties (summarized in Publication 901) may provide additional relief — though a treaty 'saving clause' generally preserves the U.S.'s right to tax its own citizens. The information below presents factual IRS requirements and current thresholds; it is not tax advice, and figures apply to the specific tax years cited. Consult the referenced IRS publications or a qualified tax professional for your situation.
Key Points
- 1Filing: U.S. citizens abroad file Form 1040 on worldwide income and receive an automatic 2-month extension to June 15 (calendar-year filers); a further extension to Oct 15 is available via Form 4868, but tax owed still accrues interest from the April due date (IRS Publication 54).
- 2FEIE amount: The Foreign Earned Income Exclusion maximum is $126,500 for tax year 2024 and $130,000 for tax year 2025, claimed on Form 2555. It excludes foreign earned income only — not passive income — and requires a foreign tax home plus passing either the Bona Fide Residence Test or the Physical Presence Test (330 full days in any 12-month period).
- 3Foreign housing: A separate foreign housing exclusion/deduction is available on Form 2555; the base housing amount equals 16% of the maximum FEIE and the general limit on qualifying expenses is 30% of the maximum FEIE (higher in designated high-cost locations).
- 4FBAR: File FinCEN Form 114 if the aggregate value of all foreign financial accounts exceeds $10,000 at any time during the calendar year. It is filed electronically through the BSA E-Filing System with FinCEN (not the IRS), due April 15 with an automatic extension to October 15.
- 5FATCA Form 8938: Taxpayers living abroad must file if specified foreign financial assets exceed $200,000 on the last day of the year or $300,000 at any time (single/separate), or $400,000 / $600,000 respectively for married filing jointly — higher than the $50,000/$100,000 thresholds for those living in the U.S. Form 8938 is filed with the IRS attached to Form 1040.
- 6Foreign Tax Credit vs. FEIE: The Foreign Tax Credit (Form 1116, Publication 514) offsets U.S. tax dollar-for-dollar with foreign income taxes paid, but no credit or deduction is allowed for foreign taxes on income already excluded under the FEIE. The FTC is generally more advantageous in high-tax countries or for income above the exclusion cap.
- 7Self-employment & estimated tax: Self-employment tax (15.3% — 12.4% Social Security plus 2.9% Medicare) applies to net self-employment earnings even if those earnings are excluded under the FEIE; a Totalization Agreement with a certificate of coverage can exempt income taxed by the host country's system. Anyone expecting to owe $1,000+ after withholding must pay quarterly estimated tax via Form 1040-ES (due ~April 15, June 15, Sept 15, and Jan 15).
