Concept
Foreign earned income exclusion and foreign tax credit are different tools. FEIE removes qualifying earned income from U.S. taxable income. Foreign tax credit offsets U.S. tax with qualifying foreign income taxes. The IRS foreign earned income exclusion page states that a U.S. citizen or resident alien living abroad is taxed on worldwide income, but may qualify to exclude foreign earnings from income up to an annually adjusted limit. The IRS foreign tax credit materials explain that the credit is designed to reduce double taxation when income is taxed by both the United States and a foreign country.
The choice is not cosmetic. FEIE can help low-tax or no-tax country earners with salary income. Foreign tax credit often works better for taxpayers in high-tax countries, taxpayers with passive income, and taxpayers who need carryovers. Neither tool cancels FBAR, Form 8938, PFIC, CFC, or trust reporting.
FEIE
FEIE is claimed on Form 2555. It applies only to foreign earned income, not passive income, investment gains, pension income, CFC inclusions, PFIC income, or trust distributions. The person must usually have a foreign tax home and satisfy either the bona fide residence test or the physical presence test.
The physical presence test is mechanical: generally 330 full days in a foreign country or countries during a 12-month period. The bona fide residence test is more factual and looks at whether the person was a bona fide resident of a foreign country for an uninterrupted period that includes an entire tax year.
FEIE can be paired with foreign housing exclusion or deduction where the taxpayer qualifies. The tax on non-excluded income is computed using the rates that would have applied without the exclusion, so FEIE is not a first-dollar rate reset.
Foreign tax credit
Foreign tax credit is usually claimed on Form 1116 for individuals. It can apply to qualifying foreign income taxes paid or accrued. The credit is limited by category and by U.S. tax on foreign-source income, so the calculation depends on income sourcing, expense allocation, and baskets.
The IRS Publication 514 explains a key rule: foreign taxes paid on income excluded under FEIE or foreign housing exclusion cannot also be used for a credit or deduction. This is the double-dipping rule. If income is excluded, the tax tied to that excluded income is not creditable.
Foreign tax credit can create carryovers where foreign taxes exceed the current U.S. limitation. That makes it more useful in high-tax countries and for taxpayers with continuing foreign-source income.
Decision table
| Fact pattern | Often better starting point | Why |
|---|---|---|
| Salary in a low-tax country | FEIE | There may be little foreign tax to credit |
| Salary in a high-tax country | Foreign tax credit | Foreign tax may offset U.S. tax and preserve future credits |
| Passive investment income | Foreign tax credit | FEIE does not apply to passive income |
| Self-employment abroad | FTC plus totalization review | FEIE may not solve self-employment tax |
| Foreign company owner | CFC analysis first | Subpart F and section 951A may not behave like salary |
| Foreign funds | PFIC analysis first | Form 8621 regimes can dominate the calculation |
| Future U.S. move | FTC often preferred | Credit carryovers may matter after relocation |
Housing and social security
Housing
Foreign housing exclusion or deduction can supplement FEIE where the person has qualifying housing expenses abroad. It is not a general rent reimbursement. It depends on the location, base housing amount, employer-provided amounts, self-employment facts, and Form 2555 mechanics. Housing relief should be documented with leases, invoices, proof of payment, employer reimbursement policy, and the period of foreign residence or presence, not guessed from bank transfers.
Social security
FEIE and FTC are income tax tools. They do not automatically solve U.S. Social Security and Medicare exposure for self-employed persons abroad. A totalization agreement can be decisive: if a U.S. person works in a country with such an agreement, it can determine whether U.S. or foreign social security applies. Without an agreement, a person can face unexpected self-employment tax even when income tax is reduced.
Checklist
- Identify earned income separately from passive income and entity income.
- Confirm the foreign tax home.
- Test bona fide residence and physical presence dates.
- Collect foreign tax assessments and payment evidence.
- Decide whether FEIE, FTC, or both on different income layers makes sense.
- Allocate foreign taxes away from excluded income.
- Check whether foreign housing relief applies.
- Check self-employment tax and totalization.
- Preserve FX method, foreign pay slips, employment contracts, and local returns.
Common mistakes
- Using FEIE for dividends, capital gains, pensions, PFIC income, or CFC inclusions.
- Claiming foreign tax credit for tax paid on income excluded by FEIE.
- Ignoring self-employment tax after excluding earned income.
- Counting travel days loosely for physical presence.
- Assuming a local tax return is enough evidence for U.S. foreign tax credit.
- Using FEIE every year without checking whether FTC carryovers would be better.
Advisor trigger
A U.S. international CPA should model FEIE and FTC side by side. A U.S. tax attorney should be involved if the position depends on a treaty, disputed residence, aggressive sourcing, foreign company compensation, prior-year amendments, or IRS correspondence.
Q&A
What is the difference between FEIE and the foreign tax credit
FEIE removes qualifying foreign earned income from U.S. taxable income on Form 2555. The foreign tax credit offsets U.S. tax with foreign income taxes paid or accrued on Form 1116. One excludes income; the other credits tax already paid abroad.
Which income qualifies for FEIE
Only foreign earned income — broadly salary and self-employment compensation for services performed abroad. Dividends, interest, capital gains, pensions, CFC inclusions, PFIC income and trust distributions are not foreign earned income and cannot be excluded.
Can the same foreign tax be used for both FEIE and the credit
No. Publication 514 sets out the double-dipping rule: foreign tax paid on income excluded under FEIE or the housing exclusion is not also creditable or deductible. Tax tied to excluded income is removed from the credit calculation.
Why is the foreign tax credit often better in a high-tax country
Because foreign income tax can offset U.S. tax on the same income and any excess can carry over. Carryovers can be valuable for taxpayers with continuing foreign-source income or a future move back to the United States, which a one-year exclusion does not provide.
Do FEIE or FTC remove self-employment tax
No. Both are income tax tools and neither cancels U.S. self-employment tax for a self-employed person abroad. A social security totalization agreement with the country of work can decide which system applies; without one, self-employment tax can remain even after income tax is reduced.
