Many Americans living abroad ask the same fundamental question: “Why do you have to pay U.S. taxes if you live abroad?” The answer lies in the United States’ policy of citizenship-based taxation — a system that requires Americans to report worldwide income regardless of where they live.
This system, shared only by Eritrea (a country in East Africa), means you must file a U.S. tax return if your income meets the minimum filing thresholds. For the 2024 tax year, these thresholds include $14,600 for single filers and $29,200 for those married filing jointly.
While filing is mandatory, this obligation does not always lead to a tax bill. A number of available tax benefits can significantly reduce or eliminate the final taxes you owe to Uncle Sam.
Understanding the Foreign Earned Income Exclusion
The Foreign Earned Income Exclusion (FEIE) allows qualifying American expats to exclude a portion of their income earned abroad from U.S. taxes. For the 2024 tax year, the maximum exclusion is $126,500, an amount that the IRS adjusts annually for inflation.
To qualify for the exclusion, you must have a tax home in a foreign country and meet one of two key tests:
- The Physical Presence Test requires you to be in a foreign country for at least 330 full days during any 12-month period.
- The Bona Fide Residence Test requires you to be a resident of a foreign country for an uninterrupted period that includes a full tax year.
You claim the FEIE by filing Form 2555 with your annual return. It is important to note that you cannot claim the Foreign Tax Credit for any income that you choose to exclude using the FEIE.
The Role of Tax Treaties and Expat Tax Benefits
The U.S. maintains tax treaties with many countries to help citizens avoid double taxation. It is a common misconception that these treaties eliminate the need to file a U.S. tax return. They do not, but they provide crucial relief mechanisms.
The primary tool for this is the aforementioned Foreign Tax Credit (FTC), which you claim by filing Form 1116. The FTC provides a dollar-for-dollar credit that directly reduces your U.S. tax liability for income taxes already paid to a foreign government.
Compliance and Filing Requirements for U.S. Expats
You must file a U.S. tax return (Form 1040) if your worldwide income exceeds the established thresholds for your filing status. While living abroad, you receive an automatic two-month filing extension to June 15, or the next business day if the date falls on a weekend or holiday, and you can request a further extension to October 15 by filing Form 4868.
Note that a filing extension is not an extension to pay. To avoid interest and penalties, you must pay any tax you owe by the original April 15 deadline.
Reporting Foreign Bank Accounts and Assets
You must report foreign financial assets to the U.S. government, a requirement separate from your income tax return that applies even if the assets do not generate taxable income. Two primary reporting obligations exist:
- You must file a Foreign Bank Account Report (FBAR) using FinCEN Form 114 if the total value of your foreign financial accounts exceeds $10,000 at any point during the year. The penalty for a non-willful failure to file can be up to $10,000 per unreported account.
- You must also file Form 8938 under the Foreign Account Tax Compliance Act (FATCA) if your specified foreign assets are valued at more than $200,000 for a single filer living abroad.
These filings are informational and separate from your annual income tax return. However, strict compliance remains important to avoid potential penalties.
Tax Implications of Foreign Investments for U.S. Expats
The IRS requires U.S. citizens to report income from all foreign investments, with different types of assets triggering their own specific reporting requirements:
- Rental income from a foreign property must be reported on Schedule E of your tax return.
- Ownership in a foreign corporation requires filing Form 5471.
- Any interest in a foreign partnership requires filing Form 8865.
- Transactions with or ownership of a foreign trust require filing Form 3520.
- Shares in a Passive Foreign Investment Company (PFIC) require filing Form 8621.
Tax treaties prevent double taxation by lowering rates on investment income, like dividends and interest, which reduces your overall liability.
Social Security Taxes and Benefits for Expats
To prevent expats from paying into two social security systems simultaneously, the U.S. maintains Totalization Agreements with many countries that dictate to which system you contribute. If you live and work in a country that does not have such an agreement, you may be required to pay social security taxes to both nations.
Note that the IRS does not classify U.S. Social Security payments as foreign earned income. As a result, you cannot exclude this income from your U.S. tax return using the Foreign Earned Income Exclusion.
Simplifying Expat Tax Compliance
Managing your U.S. tax obligations from abroad requires understanding a few key principles: you must file an annual tax return on your worldwide income, report your foreign financial accounts, and strategically use benefits like the Foreign Earned Income Exclusion and the Foreign Tax Credit to reduce what you owe.
For expats who are not current with their U.S. tax filings, the IRS offers the Streamlined Filing Compliance Procedures. This amnesty program allows individuals who certify their noncompliance was non-willful to file several years of back taxes and FBARs without facing penalties.
