Foreign Tax Credit (FTC) Explained for Americans Living Abroad

U.S. citizens and green card holders are taxed on their worldwide income, even if they live permanently outside the United States.

This means that even individuals who were not born in the U.S., have never lived or worked there, and only recently discovered their U.S. status, may still have a filing obligation. This situation is explained in (NOT) born in the US, never lived, worked or visited the US. Does that mean you still have to file taxes?

When income is taxed both by a foreign country and by the United States, double taxation can arise. To address this, U.S. tax law provides the Foreign Tax Credit (FTC), which is claimed using Form 1116.

This article explains what Form 1116 is, who qualifies, and how the Foreign Tax Credit works.

What Is Form 1116?

IRS Form 1116 is completed by individuals to claim the Foreign Tax Credit.

The Foreign Tax Credit allows taxpayers to reduce their U.S. income tax liability by the amount of qualifying foreign income taxes paid or accrued. It applies to income that is taxed both by a foreign country (or U.S. possession) and by the United States.

The purpose of the credit is to mitigate double taxation, once by the foreign jurisdiction and once by the U.S.

Form 1116 must be attached to your U.S. income tax return (IRS Form 1040).

Who Can Claim the Foreign Tax Credit?

To claim the Foreign Tax Credit using Form 1116:

• You must have paid or accrued foreign taxes to a foreign country or U.S. possession.
• The tax must have been imposed on you personally.
• The tax must be an income tax (or a tax in lieu of income tax), including certain war profits or excess profits taxes.
• You must have foreign-source income that is eligible for the credit.

Not all foreign payments qualify. For example, VAT, property taxes, or social security contributions generally do not qualify for the Foreign Tax Credit.

When Is Form 1116 Relevant?

Form 1116 is typically relevant if you:

• Pay income tax in your country of residence
• Earn foreign salary or self-employment income
• Receive foreign rental, dividend, or investment income
• Exceed the Foreign Earned Income Exclusion threshold
• Have income that does not qualify for exclusion

The Foreign Tax Credit is often used by Americans living in higher-tax countries, where local income taxes may already exceed potential U.S. tax liability.

How the Foreign Tax Credit Works

The credit reduces U.S. income tax on foreign-source income by the amount of qualifying foreign income tax paid.

However, it is subject to limitations.

Limitation Rule

The Foreign Tax Credit cannot exceed the portion of U.S. tax attributable to foreign-source income. This ensures that foreign taxes do not offset U.S. tax on U.S.-source income.

Income Categories

Foreign income must be divided into categories, such as:

• General category income
• Passive category income
• Foreign branch income

Each category is calculated separately. Incorrect categorization is a common filing mistake.

Carryback and Carryforward

If foreign taxes paid exceed the allowable credit for the year, unused credits may:

• Be carried back one year
• Be carried forward for up to ten years

This makes Form 1116 relevant not only for the current filing year but also for longer-term compliance planning.

Form 1116 vs. Form 2555

Some Americans abroad consider whether to use the Foreign Tax Credit or the Foreign Earned Income Exclusion.

The exclusion is claimed using IRS Form 2555.

The structural difference is:

• Form 2555 excludes qualifying foreign earned income from U.S. taxation.
• Form 1116 provides a credit for foreign income taxes paid.

Form 2555 is often used in lower-tax countries. Form 1116 is typically more relevant in higher-tax jurisdictions or where income types do not qualify for exclusion.

How Form 1116 Relates to FATCA and FBAR

The Foreign Tax Credit addresses income tax. It does not replace separate foreign asset reporting obligations.

Americans abroad may also be subject to:

• FATCA reporting requirements
• FBAR (Foreign Bank Account Reporting)

These reporting obligations apply independently from whether U.S. income tax is owed. Even if Form 1116 reduces U.S. tax liability to zero, foreign account reporting requirements may still apply.

Understanding the distinction between tax liability and reporting obligations is essential for full compliance.

Is Form 1116 Always Required?

In limited cases, taxpayers with small amounts of foreign tax paid may qualify for a simplified election that does not require filing Form 1116.

However, many Americans abroad must complete Form 1116 to properly claim the Foreign Tax Credit.

Whether Form 1116 is preferable to the Foreign Earned Income Exclusion depends on:

• Type of income
• Amount of foreign tax paid
• Residency situation
• Long-term compliance considerations

In Brief

Form 1116 allows Americans living abroad to claim a Foreign Tax Credit for qualifying foreign income taxes paid or accrued. The credit reduces U.S. income tax on foreign-source income and is designed to mitigate double taxation.

Although the principle is straightforward, the calculation rules are technical. Proper income categorization, application of the limitation formula, and tracking of carryovers are essential for accurate filing.

Even when the Foreign Tax Credit reduces U.S. income tax liability to zero, separate reporting obligations –  including FATCA reporting requirements and FBAR (Foreign Bank Account Reporting), may still apply.

Choosing between the Foreign Tax Credit and the Foreign Earned Income Exclusion depends on your income profile, country of residence, and long-term compliance considerations. In some cases, planning may also involve reviewing potential U.S. exit tax implications.

Need clarity on Form 1116 or the Foreign Tax Credit?

If you are reviewing Form 1116, you are likely already in the process of filing and want to ensure everything is handled correctly.

The Foreign Tax Credit can significantly reduce double taxation, but the calculations ( income categories, limitation rules, and carryovers) must be applied accurately. Small errors can affect future tax years or trigger IRS questions.
