US Tax Exile: FEIE, Foreign Tax Credits, and the Renunciation Exit Tax
The US is one of only two countries in the world that taxes citizens based on citizenship, not residence. Moving abroad does not free you from US taxes — but the FEIE and FTC can dramatically reduce the bill, and renunciation eliminates it permanently.
Citizenship-based taxation: the problem
The United States taxes its citizens and green card holders (long-term residents) on their worldwide income, regardless of where they live. This is called citizenship-based taxation (CBT). Even if you move to Dubai and pay 0% local income tax, you are still required to:
- File a US tax return every year (Form 1040)
- Report all foreign bank accounts (FBAR — FinCEN 114)
- Disclose foreign financial assets (FATCA — Form 8938)
- Pay US tax on income above certain thresholds
Non-compliance with these obligations is treated very seriously by the IRS, with significant penalties for late FBAR filings even if no tax is owed.
Path 1: Live abroad using FEIE + FTC
For most Americans living abroad, the FEIE and FTC together eliminate or drastically reduce the additional US tax burden:
Consider a US citizen earning $200,000 in earned income while living in the UAE (0% tax):
| Item | Amount |
|---|---|
| Gross earned income | $200,000 |
| FEIE exclusion | −$126,500 |
| Taxable earned income | $73,500 |
| US federal income tax on $73,500 | ~$10,800 |
| Foreign Tax Credit | $0 (UAE has no income tax) |
| FICA (SS + Medicare) | ~$14,000 (still owed) |
| Total US tax liability | ~$24,800 |
| vs. US resident tax (same income) | ~$46,000+ |
| Estimated net saving | ~$21,000/yr |
Note: FICA is owed even while living abroad unless a totalization agreement with the host country applies. Self-employed individuals pay both employee and employer shares (15.3% up to the SS wage base).
Path 2: Renounce citizenship (exit tax)
Complete freedom from US worldwide taxation requires formally renouncing US citizenship at a US consulate. The process is irreversible and triggers the exit tax under IRC §877A.
Covered expatriate thresholds (triggers full exit tax)
- • Net worth ≥ $2,000,000 on the date of expatriation
- • Average annual US net income tax over the preceding 5 years ≥ $201,000 (2025, indexed)
- • Failed to certify 5 years of US tax compliance (Form 8854)
If you are a covered expatriate, the IRS treats all worldwide assets as if they were sold on the day before expatriation — a "mark-to-market" deemed disposition. Gains above the $866,000 exclusion (2025, indexed) are taxed at long-term capital gains rates (up to 23.8% including NIIT). Tax-deferred accounts (401k, IRA) are treated as if fully distributed as ordinary income on the exit date.
What the FEIE savings don't cover
A lower tax bill is only part of the financial picture. Several recurring costs are easy to underweight when comparing the saving against the lifestyle change of moving abroad — or renouncing:
- Healthcare — Medicare doesn't pay for care received outside the US (with very limited exceptions), and there's no ACA marketplace once you're abroad. Comprehensive private international health insurance for a family commonly runs $5,000–$20,000+/year, more for older applicants.
- Losing Medicare Part A — Formally expatriating can mean losing free Part A coverage built up through payroll taxes if you don't separately qualify; Parts B and D were never free to begin with.
- International school fees — Few destinations popular with American expats offer free local schooling to foreign nationals. Budget $10,000–$30,000+ per child per year for an international school, plus enrolment fees.
- US-issued insurance — Many US life, disability, and umbrella insurers exclude or cancel coverage for policyholders who become non-resident or renounce citizenship; replacing it from abroad is often more expensive.
- Travel and visa limits after renouncing — Once you're no longer a US citizen, you lose the unrestricted right to live in and re-enter the US. Visits are generally capped at 90 days under the Visa Waiver Program (or whatever visa you hold), and returning for family events, healthcare, or business needs forward planning — with no guarantee of approval.
- The cost of visiting home — Flights and accommodation for trips back to see family are a real, recurring cost that's easy to underweight against a one-time exit tax bill or an annual FEIE saving.
Frequently asked questions
What is the bona fide residence test vs the physical presence test?
To qualify for the FEIE, you must pass one of two tests. The bona fide residence test requires you to be a bona fide resident of a foreign country for an uninterrupted period including a full calendar year. The physical presence test requires you to be present in a foreign country or countries for at least 330 full days during any 12-month period. The physical presence test is easier to plan for, since you just need to count days — but it requires leaving the US for 330 days in a rolling 12-month window.
Can I use both FEIE and FTC on the same income?
No — you cannot take the FTC on income that has been excluded under the FEIE. Each dollar of income must either be excluded (via FEIE) or credited (via FTC), not both. In high-tax countries (UK, Germany, France, Australia), the FTC is often more valuable because the foreign tax rate equals or exceeds the US rate, effectively zeroing out US tax without using up the exclusion. In low-tax countries (UAE, Cayman), the FEIE is more valuable because there is little foreign tax to credit.
What is Form 8854 and why does it matter?
Form 8854 is the Initial and Annual Expatriation Statement, filed in the year of expatriation and for the 8 years following (if needed for deferred compensation or specified tax-deferred accounts). It is used to calculate the exit tax and certify 5-year tax compliance. Failure to file Form 8854 results in being treated as a covered expatriate by default, regardless of net worth or tax history. The form must be filed with your final 1040 or 1040-NR return for the year of expatriation.
What happens to my US Social Security after renouncing?
Renouncing citizenship does not forfeit accrued Social Security benefits. You may still collect benefits based on your work history. However, payments to non-resident aliens are generally subject to 30% flat withholding unless reduced by a totalization agreement or bilateral tax treaty. The US has totalization agreements with over 30 countries (including the UK, Germany, France, Australia, Canada) that prevent dual social security contributions and determine which country's system covers you.
