The United States practices citizenship-based taxation, requiring citizens and lawful permanent residents (Green Card holders) to report worldwide income on annual federal returns regardless of where they live or earn income.
Expatriates living abroad can utilize statutory IRS tax mechanisms—specifically the Foreign Earned Income Exclusion (FEIE) and the Foreign Tax Credit (FTC)—to mitigate or eliminate double taxation on income taxed in their host countries.
Evaluating FEIE (Form 2555) vs. FTC (Form 1116)
Choosing between FEIE and FTC depends primarily on whether your country of residence maintains higher or lower income tax rates than United States federal brackets:
- Select FEIE (Form 2555): When living in low-tax or zero-income-tax jurisdictions (such as the United Arab Emirates, Qatar, Singapore, or the Cayman Islands) where foreign income consists of earned salary under statutory exclusion limits.
- Select FTC (Form 1116): When living in high-tax countries (such as the United Kingdom, Germany, France, Japan, or Australia) where local income tax rates meet or exceed US rates, enabling dollar-for-dollar tax credits that wipe out US liability and allow excess credits to roll forward.
Direct Comparison: Form 2555 vs. Form 1116
| Feature | Foreign Earned Income Exclusion (FEIE) | Foreign Tax Credit (FTC) |
|---|---|---|
| Applicable Statutory Limit | Indexed statutory cap on earned compensation | No statutory dollar ceiling |
| Eligible Income Categories | Active Earned Wages ONLY (Salary, bonus, professional fees) | Active and Passive Income (Wages, dividends, capital gains, rental income) |
| Residency Test Required | Physical Presence Test (330 days) or Bona Fide Residence | No strict 330-day requirement |
| Child Tax Credit Eligibility | Limits refundable Additional Child Tax Credit | Preserves refundable Child Tax Credit |
| Unused Credit Carryover | None (Exclusion applies annually) | 10-Year Carryforward / 1-Year Carryback |
| Roth IRA Contribution | Ineligible if 100% of income is excluded via FEIE | Permitted if taxable gross income remains |
Qualifying Tests for the Foreign Earned Income Exclusion
To claim Form 2555, taxpayers must satisfy one of two statutory IRS residency standards:
1. Physical Presence Test
Requires being physically present in a foreign country for at least 330 full 24-hour days during any consecutive 12-month period. Time spent in transit over international waters or international airspace does not count toward the 330-day minimum.
2. Bona Fide Residence Test
Requires demonstrating established legal residence in a foreign jurisdiction for an uninterrupted tax year (January 1 through December 31), substantiated by local tax returns, residential leases, and official resident visas.
Practical Expatriate Tax Scenarios
Scenario A: Professional Working in Dubai (Zero Local Income Tax)
- Earned Salary: $120,000
- Foreign Tax Paid: $0
- Election: FEIE (Form 2555)
- Result: $0 US federal income tax on the salary, as total earned income falls within statutory exclusion limits.
Scenario B: Engineer Working in London (High Local Income Tax)
- Earned Salary: $180,000
- UK Tax Paid: ~$52,000
- US Tax Assessed Before Credits: ~$38,000
- Election: FTC (Form 1116)
- Result: $0 US federal income tax owed; remaining excess foreign tax credits carry forward to offset future US liability.
Foreign Bank Account Reporting (FBAR / FinCEN Form 114)
Any US citizen holding a financial interest in or signature authority over foreign financial accounts whose aggregate maximum value exceeds $10,000 USD at any point during the calendar year must file an annual electronic FinCEN Form 114 (FBAR) by April 15th (with an automatic extension to October 15th).
