Expat vs. Immigrant: Key Differences & Tax Implications
Are you a US citizen living abroad or a permanent resident navigating life in a new country? The terms “expat” and “immigrant” might seem interchangeable, but when it comes to taxes, they represent different realities. Understanding these differences is crucial for ensuring compliance with the IRS and optimizing your tax situation.
Key Takeaways
- Expats and immigrants differ in intent — expats move temporarily (though often long-term), while immigrants relocate permanently.
- Both groups have different US tax obligations based on residency status.
- Expats often qualify for tax exclusions like the Foreign Earned Income Exclusion (FEIE) and foreign tax credits.
What Is an Expat?
An expatriate, commonly known as an expat, is someone who temporarily lives outside their home country. While the term is sometimes used broadly, it has specific implications for tax purposes, especially for US citizens and permanent residents abroad.
Key Characteristics:
- Often move for work, study, or lifestyle choices with plans to eventually return home
- Typically, do not intend to stay permanently in their host country
- Usually maintain strong financial and personal ties to their home country
- May be sent abroad by employers or choose to relocate independently
For US tax purposes, an expat is generally a US citizen or green card holder living in a foreign country. While living abroad, they retain their US citizenship or lawful permanent resident status, which means they remain within the US tax system.
For example, let’s say Sarah is a software engineer from Chicago who accepts a two-year contract with a tech company in Singapore. She rents an apartment in Singapore but keeps her house in the US, where she plans to return after her contract ends. Sarah is an expat because her move is temporary, and she maintains significant connections to the US.
What Is an Immigrant?
An immigrant is someone who moves to a new country with the intention of establishing permanent residence there. This permanent relocation distinguishes immigrants from expats and has significant implications for their taxes.
Key Characteristics:
- Seek permanent residency or citizenship in their new home country
- Establish long-term financial, legal, and social roots in their new country
- Often cut or significantly reduce ties with their country of origin
- May be motivated by economic opportunities, reuniting with family, or a better quality of life
From a US tax perspective, immigrants to the US are classified as resident aliens once they meet certain residency criteria. As resident aliens, they become subject to the same tax rules as US citizens.

US Tax Obligations for Expats
The United States has a unique citizenship-based taxation system that requires US citizens and green card holders to file tax returns regardless of where they live. This creates specific tax obligations for American expats living abroad.
Key Tax Rules for US Expats
- Worldwide income reporting: Expats must report all income earned globally, regardless of the source or location.
- FBAR filing: Expats with foreign financial accounts totaling over $10,000 at any point during the year must file a Foreign Bank Account Report (FBAR).
- FATCA compliance: The Foreign Account Tax Compliance Act (FATCA) requires expats to report certain foreign financial assets if they exceed specified thresholds.
Expats also have the advantage of several tax benefits.
- Foreign Earned Income Exclusion (FEIE): For 2025, expats can use the FEIE to exclude up to $130,000 of foreign-earned income from US taxation (up from $126,500 in 2024). This exclusion only applies to active income like wages and self-employment earnings, not passive income like investments.
- Foreign Tax Credit (FTC): Expats can claim a dollar-for-dollar credit for taxes paid to foreign governments, helping to prevent double taxation.
- Foreign Housing Exclusion (or Deduction): This allows expats to exclude or deduct certain housing costs from their taxable income, with limits based on their location.
US Tax Obligations for Immigrants
Immigrants to the United States face a different set of tax obligations. Once they establish residency in the US, they must comply with US tax laws and report their worldwide income, similar to US citizens.
Key Tax Rules for US Immigrants
- Resident alien status: Immigrants typically become US tax residents through either the green card test or the substantial presence test, which calculates the number of days spent in the US over a three-year period.
- Worldwide income reporting: Like US citizens, resident aliens must report all income earned globally on their US tax returns.
- FBAR and FATCA compliance: Similar to expats, immigrants must report foreign financial accounts and assets if they exceed certain thresholds.
And like expats, immigrants to the US also have tax benefits they can claim.
- Tax treaty benefits: Immigrants may benefit from tax treaties between the US and their home country, which can help clarify which country has taxing rights over certain types of income.
- Foreign Tax Credit: Immigrants can claim credits for taxes paid to foreign governments on foreign-source income to avoid double taxation.
Expats vs. Immigrants: Key Differences in US Tax Treatment
| Tax Implications | Expats | Immigrants |
| Tax on Worldwide Income? | Yes, but may exclude some via FEIE | Yes, immediately upon US residency |
| Eligible for Foreign Earned Income Exclusion? | Yes, up to $130,000 in 2025 | No, unless they are US green card holders living abroad |
| Eligible for Foreign Tax Credit? | Yes, for taxes paid to foreign countries on foreign sourced income | Yes, but primarily for taxes paid on foreign-source income |
| FATCA/FBAR Reporting? | Yes, if accounts exceed thresholds | Yes, for foreign accounts maintained after US residency |
| Subject to Exit Tax? | Possibly, if renouncing citizenship or long-term residency | No (unless they later become long-term residents and then renounce) |
Are You an Expat or an Immigrant?
Determining whether you’re an expat or an immigrant has significant implications for your tax obligations. To determine your status, ask yourself these questions:
- Do you intend to return to your home country eventually? If yes, you’re likely an expat.
- Are you seeking permanent residency or citizenship in your new country? If yes, you’re likely an immigrant.
- Do you need to maintain tax compliance in two countries? Expats typically must file tax returns in both their home and host countries.
- Will you eventually apply for citizenship in your new country? This suggests immigrant status.
- Have you maintained significant ties to your home country? Expats typically maintain bank accounts, property, and other connections to their home country.
However, these categories aren’t always clear-cut. Someone might initially move as an expat but later decide to stay permanently, transitioning to immigrant status. This transition can have significant tax implications and may require careful planning.

Common Challenges for Expats and Immigrants
Both expats and immigrants face unique challenges in navigating their taxes across multiple countries.
Expats face:
- Complex foreign tax laws: Each country has its own tax system, and understanding how it interacts with US tax laws can be complicated.
- Double taxation risks: Despite tax treaties and credits, some income may still be taxed by both countries.
- Banking challenges: Many foreign banks refuse to open accounts for US citizens due to FATCA reporting requirements.
- Retirement planning complications: Contributing to foreign retirement accounts can create complex tax situations.
- Currency fluctuations: Exchange rate changes can impact tax calculations and create unexpected tax liabilities.
Immigrants face:
- Navigating the US tax system for the first time: The US tax code is notoriously complex, with many rules that differ from those in other countries.
- Fulfilling tax obligations in both countries during transition: Immigrants may need to file taxes in both their home country and the US during the year of their move.
- Understanding residency start dates: Determining exactly when US tax residency begins can be complicated.
- Managing foreign assets under US tax law: Pre-existing foreign investments, businesses, and accounts must be reported properly.
- Social Security and treaty benefits: Understanding how international agreements affect Social Security contributions and benefits.
These challenges underscore the importance of seeking professional tax advice for both expats and immigrants. A tax professional with international experience can help navigate these complexities and develop strategies to minimize tax burdens while maintaining compliance.
