US Expat Taxes: The Complete Guide to FEIE vs FTC

The United States taxes its citizens on worldwide income, regardless of where they live, which almost no other country does. This means that Americans living abroad face a unique tax burden — they must file and potentially pay taxes in both the US and their country of residence.

To prevent double taxation, the US offers two primary mechanisms: the Foreign Earned Income Exclusion (FEIE) and the Foreign Tax Credit (FTC). Choosing the right one — or the right combination — can save you tens of thousands of dollars per year.

Foreign Earned Income Exclusion (FEIE) Explained

The FEIE (IRS Form 2555) allows qualifying US taxpayers living abroad to exclude up to $132,900 (2026 limit, adjusted annually for inflation) of foreign earned income from US federal taxation.

Key rules:

• Earned income only. FEIE applies to wages, salaries, self-employment income, and professional fees. It does NOT apply to investment income (dividends, capital gains, rental income, interest).
• Qualification tests. You must pass either the Physical Presence Test (330 full days in a foreign country during a 12-month period) or the Bona Fide Residence Test (established residency in a foreign country with intent to stay indefinitely).
• Foreign Housing Exclusion. In addition to the income exclusion, you can exclude qualifying housing expenses above a base amount ($21,264 for 2026) up to a cap of $39,870 in most places. This covers rent, utilities, property insurance, and similar costs — but not mortgage payments or domestic labor.
• Cannot combine with FTC on the same income. You cannot use FEIE and FTC on the same dollar of income. However, if your income exceeds the FEIE limit, you can use FTC on the excess.

Foreign Tax Credit (FTC) Explained

The FTC (IRS Form 1116) allows you to claim a dollar-for-dollar credit against your US tax liability for income taxes paid or accrued to a foreign country.

Key advantages over FEIE:

• Applies to all income types. Unlike FEIE, FTC works on investment income, rental income, and capital gains — not just earned income.
• No dollar cap, but a ceiling. There is no fixed dollar limit on the FTC, but the credit cannot exceed the US tax on your foreign income (IRC §904). Foreign tax above that ceiling is not lost: it carries over (see below).
• Carryover. Excess FTC credits can be carried back one year and forward ten years, providing future tax benefits even in years when your foreign tax exceeds your US tax.

Key limitations:

• FTC cannot exceed your US tax liability on the same foreign-source income. If your US effective tax rate is 22% and you paid 45% in foreign taxes, the FTC is limited to the 22% equivalent — the excess can be carried forward but not refunded.
• Different categories of income (passive, general, etc.) have separate FTC limitations, adding complexity to the calculation.

When to Use FEIE vs FTC: Decision Framework

The optimal choice depends on how much tax your destination actually charges on your income (not its top rate, which few people pay) and on your income composition:

The Foreign Housing Exclusion: An Often-Overlooked Benefit

In addition to the $132,900 income exclusion, the Foreign Housing Exclusion allows you to exclude qualifying housing expenses that exceed a base amount. For 2026:

• Base housing amount: $21,264 (16% of the FEIE limit)
• Cap on housing expenses: $39,870 (30% of the FEIE limit; higher in some expensive cities)
• Maximum housing exclusion: $18,606 ($39,870 - $21,264)

Qualifying expenses include rent, utilities, property insurance, parking, and furniture rental. Mortgage payments, home purchases, and domestic labor do not qualify. In high-cost cities (London, Singapore, Tokyo), the housing exclusion limit may be higher — check IRS Publication 54 for location-specific limits.

State Tax Exit Planning: The Hidden Trap

Federal taxes are only part of the picture. Several US states continue to assert tax authority on former residents, and failing to properly exit your state can result in years of unexpected state tax bills.

High-Risk States

• California: A California domiciliary stays a resident while away for a “temporary or transitory purpose”, and the Franchise Tax Board (FTB) decides that on the facts. One clear exit is the safe harbor: if you are abroad under an employment-related contract for at least 546 consecutive days, you are treated as a nonresident (unless your intangible income tops $200,000 in a year, or the main purpose is avoiding tax), and return visits of up to 45 days a year are allowed (FTB Publication 1031).
• New York: You are a NY resident if New York is your domicile, or if you keep a permanent home there for substantially all of the year and spend 184 days or more in the state. A NY domiciliary living abroad is not a resident if they spend at least 450 days of any 548-day period in a foreign country and meet the other conditions (NY Department of Taxation and Finance).
• Virginia, New Mexico, South Carolina: All three states claim continuing tax authority on domiciled residents even after physical departure. Formal domicile change is essential.

Steps to Properly Exit Your State

• Change your voter registration to your new jurisdiction (or cancel it)
• Surrender your driver's license and obtain a new one in your destination
• Update your bank accounts and financial institutions with your new address
• Close local business registrations and professional licenses
• File a part-year resident return for your departure year
• Document your departure date and establish ties to your new location

FBAR and FATCA: Mandatory Reporting for Expats

Moving abroad triggers two important reporting obligations:

• FBAR (FinCEN Form 114): If the aggregate value of your foreign financial accounts exceeds $10,000 at any point during the calendar year, you must file an FBAR. This includes bank accounts, investment accounts, and even accounts you have signature authority over but do not own. Due April 15 with automatic extension to October 15. Penalties for non-compliance can be severe — up to $165,353 or 50% of the account balance, whichever is greater, per account for a willful violation.
• FATCA (Form 8938): If your foreign financial assets exceed $200,000 (single) or $400,000 (married filing jointly) at the end of the tax year, or $300,000/$600,000 at any point during the year (for US persons residing abroad), you must report them on Form 8938 with your tax return. FATCA and FBAR have overlapping but different requirements — you may need to file both.

Tax Treaty Benefits

The US has income tax treaties with over 60 countries. These treaties can provide additional benefits beyond FEIE and FTC:

• Reduced withholding rates on dividends, interest, and royalties
• Exemptions for certain types of income (pensions, government pay) — though most treaties' saving clause stops US citizens using them against US tax
• Tie-breaker rules for dual-residence situations
• Mutual agreement procedures for resolving double-taxation disputes

Treaty benefits are claimed on IRS Form 8833 and may interact with your FEIE/FTC strategy. This is another reason to work with a qualified international tax professional — treaty provisions can be complex and country-specific.

Common Expat Tax Mistakes

• Assuming you do not owe US taxes. Many Americans abroad mistakenly believe that living overseas exempts them from US filing requirements. The filing requirement exists regardless of where you live or how much foreign tax you pay.
• Missing the FBAR deadline. FBAR is filed separately from your tax return and has different penalties. A non-willful failure to file can cost up to $16,536 per FBAR report (not per account — Bittner v. United States, 598 U.S. 85 (2023)): the $10,000 statutory maximum, inflation-adjusted under 31 CFR 1010.821 for penalties assessed from January 17, 2025.
• Using FEIE on investment income. FEIE only applies to earned income. If your income is primarily dividends, capital gains, or rental income, FEIE provides zero benefit. Use the FTC instead, if the destination taxes that income: some countries (Singapore, Hong Kong and the UAE among them) do not tax an individual's foreign investment income, so there is nothing to credit.
• Not planning the state exit. Moving abroad without properly changing your state domicile can result in years of state tax bills. This is especially true for California and New York residents.
• Ignoring self-employment tax. FEIE excludes income from federal income tax, but does NOT exempt you from self-employment tax (Social Security and Medicare). Self-employed expats may still owe 15.3% SE tax unless they are covered by a foreign social security system under a totalization agreement.

Frequently Asked Questions

What is the FEIE limit for 2026?

The FEIE limit for 2026 is $132,900 per qualifying individual. This amount is adjusted annually for inflation. For married couples where both spouses qualify, each can claim their own exclusion on their own earned income — up to $265,800 combined. The calculator above models one earner per run (one exclusion), so if you both work, run it once per spouse with that spouse's earned income.

Can I use both FEIE and FTC?

Not on the same income. However, you can use FEIE on your earned income (up to the limit) and FTC on income that exceeds the FEIE limit or on investment income that does not qualify for FEIE. This combination strategy can be powerful for high-income expats with mixed income types.

Do I still pay Social Security taxes as an expat?

If you are self-employed, yes — unless your destination country has a Social Security totalization agreement with the US and you are covered by that country's social security system. If you work for a US employer abroad, your employer typically continues withholding FICA taxes. Foreign employers generally do not withhold US Social Security.

What happens if I do not file FBAR?

Non-willful violations carry a penalty of up to $16,536 per FBAR report (not per account — Bittner v. United States, 2023). Willful violations are assessed per account and can result in penalties of $165,353 or 50% of the account balance, whichever is greater, plus potential criminal prosecution. The IRS has streamlined filing procedures for taxpayers who are non-willfully behind on their FBAR filings.

How long do I need to be abroad to qualify for FEIE?

Under the Physical Presence Test, you must be present in a foreign country for 330 full days during any 12-month period (not necessarily the calendar year). Under the Bona Fide Residence Test, you must establish tax home and residence in a foreign country for an uninterrupted period that includes an entire tax year. The Physical Presence Test is more straightforward; the Bona Fide Residence Test has more flexibility but requires stronger evidence of foreign residency intent.
