1 / 7

FEIE vs. Foreign Tax Credit Decision

The Foreign Earned Income Exclusion (FEIE) may exclude up to $126,500 (2025) of foreign earned income from US taxation entirely
The Foreign Tax Credit (FTC) offsets US tax dollar-for-dollar for taxes paid to a foreign government — generally more beneficial in high-tax countries
You typically cannot use both the FEIE and FTC on the same income, so choosing the right approach depends on your specific tax situation
The FEIE may be more advantageous in low-tax or no-tax countries, while the FTC often works better when foreign tax rates exceed US rates — consult a tax advisor

Physical Presence vs. Bona Fide Residence

To qualify for the FEIE, you generally must meet either the physical presence test (330 days in a foreign country during any 12-month period) or the bona fide residence test
The physical presence test is typically simpler but requires careful day-counting — days in transit and partial days in the US generally count against you
Bona fide residence requires establishing a tax home in a foreign country with the intent to remain indefinitely, which is more flexible but harder to document
If you travel frequently between countries, the physical presence test may be difficult to meet — maintain detailed records of your travel dates

Tax Treaty Planning

The US has income tax treaties with over 60 countries that may reduce or eliminate withholding on dividends, interest, and royalties
Tie-breaker rules in treaties may help resolve dual-resident status when both countries claim you as a tax resident
Treaty benefits must generally be affirmatively claimed on your tax return — they are typically not applied automatically
Competent authority procedures may be available to resolve disputes when two countries both seek to tax the same income

Timing of Repatriation

Moving back to the US triggers important tax planning considerations — the transition year often presents both opportunities and risks
Accelerating earned income into your last year abroad may allow you to use the FEIE on that income before losing eligibility
Deferring deductible expenses to your first full US tax year may increase their value when your marginal rate may be higher
Stock option exercise timing around a move date can significantly affect tax treatment — state tax residency establishment dates vary by state

Investment Income Abroad

The FEIE generally does not cover investment income (dividends, interest, capital gains) — only earned income from personal services typically qualifies
The foreign tax credit may help offset US taxes on investment income if the foreign country also taxes that income
Passive Foreign Investment Company (PFIC) rules may impose punitive taxation on foreign mutual funds and ETFs held by US persons
Holding US-domiciled investments may help avoid complex PFIC reporting and the generally unfavorable tax treatment of foreign funds

Retirement Account Considerations

Foreign employer retirement plans may not receive US tax-deferred treatment unless a specific tax treaty provision applies
Totalization agreements with approximately 26 countries may help avoid double Social Security taxation and preserve benefit eligibility
Roth IRA contributions generally require US-source earned income — expats relying solely on the FEIE may have limited or no eligibility to contribute
Some tax treaties may protect US retirement accounts (IRAs, 401(k)s) from taxation by the foreign country — review the specific treaty provisions

Compliance Requirements

Annual FBAR filing (FinCEN 114) is generally required if the aggregate value of foreign financial accounts exceeds $10,000 at any point during the year
FATCA Form 8938 may be required for specified foreign financial assets above certain thresholds, which are higher for expats than domestic filers
Form 3520 is typically required for transactions with foreign trusts or receipt of large gifts from foreign persons — deadlines and penalties are strict
Some states (notably California, New Mexico, South Carolina, and Virginia) may continue to assert tax residency even after you move abroad — consult a state tax advisor
