TL;DR: The Foreign Earned Income Exclusion (FEIE) lets you exclude up to $132,900 (2026) of foreign-earned income from U.S. tax. The Foreign Tax Credit (FTC) gives you a dollar-for-dollar credit against U.S. tax for foreign income tax already paid. They sound similar; they behave very differently. FEIE wins in low-tax countries (Portugal under IFICI, Mexico for some earners, the UAE, Singapore, the Bahamas). FTC wins in high-tax countries (Canada, Germany, France, Australia, the U.K., most of Western Europe at default rates). The wrong choice can cost you $5,000–25,000/year. This guide shows you how to pick correctly and avoid the trap of switching between them.

The 30-second decision

How the FEIE actually works

The Foreign Earned Income Exclusion (Form 2555) lets you exclude foreign-earned income from your U.S. taxable income, up to a yearly cap that adjusts for inflation. For 2026 the cap is $132,900 per qualifying person ($265,800 for a married couple where both qualify). To qualify you must:

• Have a “tax home” in a foreign country (where you regularly work and live), and
• Pass either the Bona Fide Residence test (resident of a foreign country for an uninterrupted tax year) or the Physical Presence test (330 full days in a foreign country within any 12-month period).

The exclusion only applies to earned income — wages, salary, self-employment net profit, professional fees. It does not apply to dividends, interest, capital gains, rental income, pensions, Social Security, or alimony. There’s also an optional Foreign Housing Exclusion for housing costs above a base amount, capped at 30% of the FEIE for high-cost cities.

How the FTC actually works

The Foreign Tax Credit (Form 1116) lets you reduce your U.S. tax bill dollar-for-dollar by the amount of foreign income tax you’ve already paid on the same income. There’s no income type restriction — earned, passive, and re-sourced-by-treaty all qualify, but each is calculated in a separate “basket” with its own limitation.

The credit is capped: you can never use more FTC in a year than the U.S. tax that would have been due on the foreign-source income. If foreign tax exceeds U.S. tax on that income, you carry the excess back 1 year and forward 10 years — meaningful when you anticipate income spikes.

Most expats in high-tax countries accumulate large FTC carryovers over time. A U.S. citizen working in Toronto on $150K USD will pay roughly $20,000 more in Canadian tax than the U.S. would have charged — that excess becomes carryforward fuel for any future year when U.S. rates briefly exceed Canadian rates.

The five-year switching trap

Here is the rule almost everyone misses: once you revoke an FEIE election, you cannot re-elect FEIE for five tax years without IRS consent. So if you take FEIE in years 1–3, switch to FTC in year 4 because you moved to Canada, you cannot return to FEIE until year 9 even if you move to a low-tax country in year 5.

This means the choice should be made strategically, not opportunistically. If you might move from a low-tax country to a high-tax country (or vice versa) within five years, the FTC is usually safer because it has no penalty for switching back.

Worked examples — same income, dramatically different outcomes

Case 1: $132,900 W-2 income, Single, Portugal IFICI (20% flat rate)

Income: $132,900 USD
Portuguese tax (IFICI): $26,000
U.S. tax before credit/exclusion: ~$22,400
With FEIE: $0 U.S. tax (entire income excluded). Total tax burden: $26,000.
With FTC: Foreign tax ($26,000) > U.S. tax ($22,400), so FTC fully zeros out U.S. tax and you carry forward $3,600. Total tax burden: $26,000.
Either works. But FEIE is simpler. FTC is better only if you expect to want IRA contributions or refundable child credits.

Case 2: $200,000 W-2 income, Single, Canada (Ontario)

Income: $200,000 USD (~$273,000 CAD)
Canadian tax: ~$92,000 CAD (~$67,200 USD)
U.S. tax before credit/exclusion: ~$41,600
With FEIE only: $132.9K excluded. U.S. tax on remaining $70K still due — ~$13,200 owed to U.S. plus full Canadian tax. Total: $80,400.
With FTC only: Foreign tax ($67,200) zeroes out U.S. tax ($41,600) entirely, plus $25,600 carryforward. Total: $67,200.
FTC saves $13,200/year in this case. Most Canadian-resident Americans use FTC alone. See Canada vs US taxes for the full mechanics.

Case 3: $90,000 self-employment income, UAE (no income tax)

Income: $90,000 SE net
UAE tax: $0
U.S. SE tax (always due): ~$12,700
U.S. income tax before credit/exclusion: ~$11,800
With FEIE: Income tax = $0 (excluded). SE tax still $12,700. Total: $12,700.
With FTC: Foreign tax = $0, so FTC = $0. Full $11,800 income tax due plus $12,700 SE tax. Total: $24,500.
FEIE saves $11,800/year here — clear win in low-tax jurisdictions.

Case 4: $80,000 W-2 + $40,000 dividends, Mexico

Earned income: $80,000 (Mexican tax: ~$15,500)
Dividend income: $40,000 from U.S. brokerage (Mexican tax on dividends if resident: ~$6,000; U.S. qualified-div tax: ~$4,000)
With FEIE: $80K excluded — $0 U.S. tax on earnings. But dividends still taxed at U.S. rates with no FEIE benefit; FTC still needed for the dividend basket. Mexican tax on earnings just paid for nothing. Net U.S. tax: ~$4,000 (no offset).
With FTC only: $15,500 Mexican tax on earnings credits $11,200 of U.S. tax, fully zeroing earned income; $6,000 Mexican dividend tax credits the $4,000 U.S. dividend tax. Total U.S. tax: $0.
FTC saves $4,000/year by using one tool consistently across both income types.

FEIE plus FTC — the combo nobody talks about

You can use both in the same year, but FEIE goes first. Whatever earned income exceeds the $132.9K cap, plus all unearned income, falls into the FTC calculation. The combo makes sense in narrow scenarios:

• Earned income above $132.9K in a moderate-tax country (you exclude $132.9K, FTC the excess)
• Mixed earned + investment income where the country taxes both

The catch: when computing FTC after FEIE, you reduce the FTC limitation proportionally — IRS Form 1116 line 18 handles this. You can’t double-dip on the same dollars.

Self-employment tax: the FEIE blind spot

Self-employment tax (15.3% on net SE income up to the FICA cap, 2.9% Medicare beyond it) is owed regardless of whether you take FEIE. The exclusion only reduces income tax, not SE tax. In high-cost-of-living foreign countries, SE tax can exceed local employee social-insurance rates, making the U.S. SE filing painful for self-employed expats.

The fix: if your foreign country has a Totalization Agreement with the U.S. (Canada, Mexico, Portugal, Spain, Germany, U.K., and ~25 others), you can file a Certificate of Coverage and pay only into the foreign country’s social system, eliminating U.S. SE tax. This is a small piece of paperwork that saves $10,000+/year for many expats. We cover the mechanics in the expat tax guide.

Six 2026 quirks that change the FEIE/FTC math

1. Stacking rule: FEIE-excluded income still pushes your remaining income into higher U.S. brackets (it’s “added back” for rate-determination purposes). High earners using FEIE pay higher rates on their non-excluded income than they otherwise would.
2. State tax: California, Virginia, New Mexico, and South Carolina don’t recognize FEIE. If you remain a state-tax resident, FEIE doesn’t help against state tax. See our FBAR + California exit tax guide for the domicile-break checklist.
3. Roth IRA contributions: Require taxable U.S. compensation. FEIE-excluded income doesn’t count. FTC users can usually still contribute up to the limits.
4. Refundable Child Tax Credit: The portion of CTC that becomes refundable depends on earned income. FEIE reduces earned income for CTC purposes; FTC doesn’t.
5. QBI deduction: Self-employed expats using FEIE generally cannot claim the 20% QBI deduction on excluded income. FTC users can.
6. Bona Fide vs Physical Presence: Bona Fide is harder to qualify for in year one (requires a full uninterrupted tax year as a foreign resident) but unlocks for partial years thereafter; Physical Presence’s 330-day rule is rigid every year.

How to switch (when you should)

Switching from FEIE to FTC is unrestricted — you simply stop filing Form 2555 and start using Form 1116. But you’ve now triggered the 5-year lockout on returning to FEIE.

Switching from FTC to FEIE requires only that you qualify under one of the residency tests. No restriction. But you need to think about whether your country justifies the switch — if Portuguese rates rise or IFICI eligibility lapses, you may want to reverse, and that’s where the 5-year lockout bites.

Practical rule: start with FTC unless you’re certain you’ll be in a low-tax country for 5+ years. Most cross-border CPAs default new clients to FTC for this reason.

What software handles this well

• ExpatFile ($150–250) — purpose-built for U.S. expats, handles FEIE/FTC switching and the 5-year lockout warnings.
• MyExpatTaxes ($199–349) — similar quality, slightly more hand-holding.
• TurboTax / H&R Block — both support FEIE and FTC but UX is poor for the edge cases. Many expats outgrow them after year one.
• Cross-border CPA ($1,500–4,000/year) — recommended for your first move-year, any year with self-employment, and anyone with $1M+ in assets.

Frequently asked questions

Can I use FEIE if I keep a U.S. address?

Sort of. Your “tax home” must be in the foreign country, which usually means your principal place of work. A short-term U.S. mailing address won’t disqualify you, but spending substantial time at a U.S. residence will. The Bona Fide test is forgiving here; the Physical Presence 330-day rule is rigid.

Does FEIE help with Social Security tax?

No. FEIE only reduces income tax. Social Security and Medicare (FICA for employees, SE tax for self-employed) are owed on covered earned income regardless. Totalization Agreements are the lever to reduce or eliminate these.

I just moved abroad mid-year — can I use FEIE for the partial year?

Yes, prorated. The Physical Presence test allows the 12-month qualifying window to start in the prior or following calendar year. Your CPA will calculate the prorated FEIE cap for the months you qualified.

What if my country’s tax is roughly equal to U.S. tax?

Use FTC. It’s more flexible (covers all income types), preserves your ability to contribute to retirement accounts, and avoids the 5-year switching lockout.

Is the FTC carryover useful?

Very. Most U.S. expats in high-tax countries accumulate $50K–500K of unused FTC over a career. It can offset future U.S. tax on the same income category — particularly useful when you anticipate a year with U.S.-source spike income (book deal, equity exit, return-to-U.S. transition year).

Can I take both in the same year?

Yes — FEIE applies first to qualifying earned income up to the cap, then FTC applies to remaining income. Most software handles the proration automatically.

Bottom line

The FEIE is the right tool in low-tax countries; the FTC is the right tool in high-tax countries. The wrong choice — usually defaulting to FEIE because it’s simpler — can cost mid-career professionals $10K–25K per year and forfeit retirement-account contributions. The single most common mistake is using FEIE in Canada, Germany, or France because “everyone does.”

If you’re moving to Canada, the U.K., Germany, France, or Australia: default to FTC. If you’re moving to Portugal under IFICI, the UAE, Singapore, or the Bahamas: FEIE is usually the simpler and equivalent (or better) outcome. For everywhere else, model both for your actual numbers — or pay a cross-border CPA $1,500 to do it once and save it as your default for the next decade.
