Foreign Tax Credit vs Foreign Earned Income Exclusion
Compare Form 1116 and Form 2555 by what each changes on the U.S. return—not by a generic high-tax-country versus low-tax-country shortcut.

The Foreign Tax Credit (Form 1116) and Foreign Earned Income Exclusion (Form 2555) can both reduce U.S. income tax for Americans abroad, but they operate at different points in the return. One credits qualifying foreign income tax; the other excludes qualifying foreign earned income after the tax-home and residence/presence requirements are met.
| Question | Foreign Tax Credit | FEIE |
|---|---|---|
| Primary input | Qualifying foreign income tax and foreign-source income | Qualifying foreign earned income and residence/presence facts |
| Income scope | Category-specific; can include earned and passive categories | Earned income only |
| Annual limit | U.S.-tax limitation by category | Indexed exclusion cap plus separate housing rules |
| Unused amount | Carryback/carryforward rules can apply | Unused exclusion does not carry forward |
| Separate filing | Form 1116, often one per category | Form 2555 |
Why the headline tax rate is not enough
A high foreign tax rate often makes the FTC relevant, and low-tax-country earnings often make the FEIE relevant, but that is only a starting hypothesis. The actual outcome can change with income source, the FTC limitation, prior carryovers, excluded-income allocation, children, housing, IRA compensation and the rest of the return.
Investment income and PFICs remain separate
Form 2555 does not exclude dividends, capital gains or PFIC income. A foreign fund can still require Form 8621. Foreign tax on investment income may belong in a passive-category Form 1116, but PFIC rules can change character and timing, so the inputs need to come from the actual holding calculation.
