IRS Form 2555: Foreign Earned Income Exclusion

The short answer

What Form 2555 is

Form 2555 is the US tax form through which individuals claim the Foreign Earned Income Exclusion. The exclusion allows qualifying US taxpayers who live and work abroad to exclude a portion of their foreign earned income from US taxation. For an American employed in the UK, it can be a significant tool for reducing exposure to double tax on salary and similar earnings.

The exclusion applies to earned income, such as wages and self-employment income, rather than to passive income like dividends or interest.

Why Form 2555 exists

Because the United States taxes citizens on worldwide income, Americans working abroad would otherwise face US tax on income they earn entirely overseas. The Foreign Earned Income Exclusion exists to relieve that burden for genuine residents abroad, recognising that their earned income already has a strong connection to their country of residence.

Who generally files Form 2555

  • US citizens and residents living abroad with foreign earned income.
  • Americans employed or self-employed in the UK seeking to exclude qualifying earnings.
  • Taxpayers weighing the exclusion against the Foreign Tax Credit.
  • Long-term expatriates whose residence abroad supports an exclusion claim.

How Form 2555 relates to other filings

Form 2555 is most naturally understood alongside Form 1116. Both aim to prevent double taxation of foreign income, but the exclusion removes qualifying earned income from the US base, while the credit offsets US tax with foreign tax paid. Many Americans in the UK need to weigh the two, and the interaction with the US–UK tax treaty adds further nuance. Our calculator helps illustrate the trade-off.
