Foreign Tax Credits vs. the Foreign Earned Income Exclusion: Which Benefits You More?

The double taxation problem for U.S. expats

The United States taxes its citizens and permanent residents on their worldwide income — regardless of where they live or where the income is earned. This means a U.S. citizen living and working in Germany, Japan, or Australia is potentially subject to both U.S. income tax and the income tax of their country of residence on the same earnings. To mitigate this double taxation, the U.S. tax code provides two primary mechanisms: the Foreign Earned Income Exclusion (FEIE) and the Foreign Tax Credit (FTC). Understanding which one benefits you more in a given year requires careful analysis.

The Foreign Earned Income Exclusion (FEIE)

The FEIE allows qualifying U.S. taxpayers living abroad to exclude a portion of their foreign earned income from U.S. taxable income. For 2024, the exclusion amount is $126,500, adjusted annually for inflation. To qualify, the taxpayer must have foreign earned income, have a tax home in a foreign country, and meet either the bona fide residence test (established residence in a foreign country for an uninterrupted period including an entire tax year) or the physical presence test (presence in a foreign country for at least 330 full days during any 12-month period).

The FEIE applies only to earned income — wages, salaries, and self-employment income. It does not apply to passive income such as dividends, interest, rental income, or capital gains. A companion provision, the Foreign Housing Exclusion or Deduction, allows qualifying taxpayers to exclude or deduct certain foreign housing costs above a base amount.

The Foreign Tax Credit (FTC)

The Foreign Tax Credit allows U.S. taxpayers to offset U.S. income tax liability by the amount of income tax paid or accrued to a foreign government on the same income. Unlike the FEIE, which excludes income from the tax base, the FTC operates as a dollar-for-dollar credit against U.S. tax liability. The FTC is available for both earned and unearned income, and it is subject to limitation rules that separate income into various categories ("baskets") — most importantly the general limitation basket and the passive income basket.

Excess foreign tax credits that cannot be used in the current year can be carried back one year and carried forward ten years, providing planning flexibility that the FEIE does not offer.

When the FEIE is advantageous

The FEIE tends to be more beneficial when the taxpayer's foreign country tax rate is lower than the U.S. rate — or when no foreign income tax is paid at all. In low-tax jurisdictions, using the FEIE eliminates U.S. tax on up to $126,500 of earned income without needing a foreign tax credit to offset a U.S. liability. It can also be advantageous for self-employed expats, though the FEIE does not reduce self-employment tax — only income tax.

When the FTC is advantageous

The FTC is generally more beneficial when the taxpayer lives in a high-tax country and pays foreign income tax at rates equal to or exceeding U.S. rates. In those situations, the foreign taxes paid can fully offset the U.S. tax liability on the same income — effectively eliminating U.S. tax without using up the FEIE exclusion amount. The FTC is also preferable when the taxpayer has significant passive income, retirement account contributions, or other U.S. tax attributes that interact poorly with the FEIE's tax base reduction mechanics.

The interaction problem: you generally cannot use both on the same income

A taxpayer who elects the FEIE cannot also claim the FTC on the same income that was excluded. This interaction can create unexpected traps — for example, income excluded under the FEIE cannot generate a foreign tax credit, but the foreign tax paid on that income is also lost. In some high-tax situations, using the FEIE can actually result in a higher overall tax burden than simply using the FTC. The election to use the FEIE can be revoked, but revocation carries a five-year bar on re-election — making the initial choice consequential.
