Foreign tax credit or foreign earned income exclusion — which one should I pick?
If your foreign income tax is higher than what the US would charge, pick the foreign tax credit (FTC) — it wipes out the US bill and banks unused credit for up to 10 years. If your foreign tax is lower or zero, pick the foreign earned income exclusion (FEIE) — it removes up to $132,900 of earned income from US tax. The hard rule: you cannot use both on the same dollars, so run the numbers on both forms before you commit.
The one rule that governs everything
You cannot claim the foreign earned income exclusion and a foreign tax credit (or deduction) for taxes on the same income. The IRS is explicit: if you exclude income on Form 2555 and then take a credit for foreign tax paid on that excluded income, the exclusion election is revoked. The two tools can sit side by side on one return — the FEIE on the first dollars, the FTC on the dollars above the exclusion — but they can never overlap.
How each tool works
Foreign earned income exclusion (Form 2555). For 2026, you can exclude up to $132,900 per qualifying person of foreign earned income — wages, salaries, and self-employment earnings from work performed abroad. It does not cover dividends, interest, capital gains, pensions, or rental income. You must have a foreign tax home and pass either the physical presence test (330 full days abroad in any 12-month period) or the bona fide residence test (foreign residence spanning a full calendar year).
Foreign tax credit (Form 1116). A dollar-for-dollar credit for income tax you paid to a foreign government, applied against the US tax on that same income. There is no fixed dollar cap, but the credit is limited to the US tax attributable to your foreign-source income. The excess carries back one year and forward up to ten years in the same income category (carryforward confirmed in IRS Publication 514 and §904(c)).
The comparison table
| FEIE | FTC | |
|---|---|---|
| Cap | $132,900 per person (2026) | None — capped by US tax on that income |
| Income covered | Earned income only | Earned and passive (interest, dividends, rent) |
| Forms | Form 2555 | Form 1116 |
| Best when | Foreign tax is low or zero | Foreign tax exceeds US tax |
| Self-employment tax | Not reduced | Not reduced |
| Unused benefit | Lost (nothing carries forward) | Carries back 1 yr, forward 10 yrs |
| IRA contributions | Excluded income cannot fund an IRA | Income stays in gross income — IRA eligible |
| Refundable child tax credit | Unavailable when you file Form 2555 | Remains available |
| Changing course | Revoking the exclusion locks you out for 5 years without IRS consent | Switch between credit and deduction year to year |
Why the tax rate of your country decides
The logic is mechanical. In a high-tax country (much of Western Europe, the UK, Canada, Australia, Japan), the foreign tax on your income usually exceeds the US tax on it, so the FTC absorbs the entire US bill — and the extra credit is banked for ten years. In a low- or zero-tax country, there is little foreign tax to credit, so the FEIE's flat exclusion wins. In the middle, run both.
What the current-year comparison hides
Three side effects often matter more than this year's bill:
- IRA eligibility. IRA contributions require compensation included in gross income. If the FEIE excludes all your earned income, you cannot contribute to a Traditional or Roth IRA that year. The FTC route keeps the income visible and preserves IRA room.
- Refundable child tax credit. The IRS states you cannot take the additional child tax credit if you exclude foreign earned income. Filing Form 2555 — even for only the housing exclusion — removes the refundable portion for the whole year.
- Revocation lockout. Once you elect the FEIE, revoking it bars re-election for five tax years without IRS permission. The FTC has no such trap — often the deciding factor for families whose situation may change.
Frequently asked questions
Can I use the FEIE for part of my income and the FTC for the rest?
Yes. The FEIE covers the first $132,900 of eligible foreign earned income; foreign taxes on income above that go on Form 1116. You may not credit foreign tax on the excluded portion.
What if both routes produce zero US tax this year?
Common in high-tax countries — the current-year comparison then decides nothing. Choose on the side effects: the FTC preserves IRA eligibility and the refundable child tax credit, and banks excess credits for ten years.
Does the FEIE election affect my spouse?
Each spouse is evaluated separately — if both qualify, each can exclude up to $132,900 on a joint return. But one spouse's Form 2555 can affect the whole joint return: for example, the refundable child tax credit is lost for the entire return if either spouse files Form 2555.
