Expat Tax Advice: How to Navigate U.S. Taxes While Living Abroad

Living abroad comes with plenty of perks: better weather, stronger coffee, and the chance to reinvent yourself at least once a year. But even if you’ve traded New York for Hong Kong or settled into a cozy village in the United Kingdom, one thing still follows you: U.S. taxes.

That’s why the right expat tax advice matters—because the IRS doesn’t care where you live. If you’re a U.S. citizen or green card holder, you’re required to file a federal income tax return every tax year, even if you haven’t set foot in the U.S. in ages. And once you add in foreign income, local tax rules, multiple currencies, and maybe a bank account (or five), things get complicated fast.

Without the right strategy, even simple filings can spiral. The right advice isn’t just helpful—it’s essential.

Do American expats still pay U.S. taxes?

Even if you live abroad full-time, you’re still on the hook for U.S. taxes.

That’s because the U.S. is one of the only countries in the world that taxes based on citizenship, not residency. If you’re a U.S. citizen, green card holder, or meet the substantial presence test, you’re required to report your worldwide income—no matter where you earn it, spend it, or stash it.

Filing requirements vary depending on your filing status, income level, and whether you’re self-employed, employed abroad, or retired.

For example, if you’re a self-employed expat earning just $400, you’re required to file an income tax return. And if you’re earning income in multiple currencies (and countries), tax filing gets even more complex.

How international tax rules apply to you depends largely on how you’re earning:

• Employees need to navigate U.S. reporting alongside foreign payroll systems.
• Business owners must account for foreign entities and bank accounts.
• Retirees need to consider the tax treatment of pensions, investments, and social security abroad.

Whether you’re freelancing from Lisbon or running a business in Athens, the bottom line is the same: you still need to file.

Which documents do expats need to file a U.S. tax return?

When it comes to filing your expat tax return, the paperwork matters. A missing form or overlooked detail can lead to unexpected tax liability, processing delays, or even penalties.

Here’s what most expatriates should gather before getting started:

• Income records: W-2s, 1099s, or foreign equivalents for employment, freelance, or passive income.
• Foreign employment details: Pay stubs, contracts, and tax slips from non-U.S. employers.
• Bank account information: Including balances for any foreign financial accounts you’ve held during the year.
• Proof of housing costs: If claiming the Foreign Housing Exclusion, you’ll need rent receipts, utility bills, or lease agreements.
• Investment and retirement statements: To report interest, dividends, capital gains, or foreign pensions.
• Social Security or foreign government benefits: Especially if you’re retired or semi-retired abroad.
• Previous U.S. tax filings, if available: These help your preparer assess carryovers, losses, or credits from past years.

Many tax professionals use a secure questionnaire to streamline this process. It ensures your information is complete and helps avoid common issues like:

• Currency conversion errors
• Forgotten bank accounts that trigger FBAR filing
• Incomplete employer or pension details
• Missing documents that affect foreign tax credits or exclusions

If your tax situation involves multiple countries or income types, getting organized early is key. And if you’re unsure whether something is reportable, a quick consult with a tax expert can save you a world of stress—and possibly a case of double taxation.

Tax deductions and credits for U.S. expats

The good news? While the U.S. taxes your worldwide income, it also gives you a few solid tools to avoid being taxed into oblivion.

Two of the most valuable are:

• Foreign Earned Income Exclusion (FEIE): This lets you exclude up to $130,000 of foreign-earned income (2025 tax year) if you meet either the physical presence or bona fide residence test. It’s especially handy if you’re earning a steady salary in places like Singapore, Germany, or the UAE.
• Foreign Tax Credit (FTC): This allows you to claim a dollar-for-dollar credit for income taxes paid to another country. It’s often the better choice if you’re in a higher-tax country or don’t qualify for the FEIE.

Both require detailed tax documents and a clear understanding of your tax obligations. They can also get a little messy if you try to use both at the same time—so if you’re splitting time between multiple countries, or dealing with dual incomes, it may be time to call in a tax advisor.

Tax implications for remote workers and property owners abroad

Living overseas doesn’t exempt you from U.S. tax obligations—especially if you’re still earning income or holding assets tied to the United States.

Federal tax obligations for remote workers

If you’re working remotely for a U.S.-based employer or client, while physically located abroad, your income is generally considered foreign-sourced—even if it’s paid into a U.S. bank account or issued by a U.S. company. That means it must still be reported on your U.S. tax return, but it may not be subject to U.S. tax, especially if you qualify for exclusions like the Foreign Earned Income Exclusion (FEIE) or the Foreign Tax Credit (FTC).

Tax reporting for foreign property owners

Owning property abroad introduces several U.S. tax considerations:

• Rental income must be reported on your U.S. income tax return.
• Capital gains from a property sale may be taxed by both the U.S. and the local country.
• You may need to document expenses such as maintenance, insurance, and depreciation.
• Additional reporting may be required if the property is held through a foreign corporation or trust.

Retirement income and social security for expats

Many forms of retirement income remain taxable, even when you live abroad:

• U.S. pension distributions and IRA withdrawals are typically taxable by the IRS.
• Social security benefits may be partially taxed, depending on your income and country of residence.
• Tax treaties may reduce or eliminate double taxation, but must be properly applied on your return.

Failing to understand these tax implications can lead to missed filings, penalties, or unnecessary tax payments.

What about state taxes?

Moving abroad doesn’t always mean you’re off the hook for state taxes.

Some states—often called “sticky states”—have stricter rules for determining whether you’ve truly cut ties. If you still have a bank account, active driver’s license, voter registration, or real estate in the state, they may continue to consider you a resident for tax purposes.

To officially end your state residency, you may need to:

• Sell or rent out your property
• Close or relocate financial accounts
• Update your driver’s license and voter registration
• Show clear intent to live outside the U.S. permanently or indefinitely

Each state has different tax laws and thresholds, so it’s important to review your situation carefully. States like California, New Mexico, and New York are especially known for auditing expats who attempt to break residency without a full paper trail.

Tax planning for long-term expats and returnees

Whether you’re planning to move back to the U.S. or renounce your citizenship, long-term expats face unique tax considerations that require careful, forward-looking planning.

Tax consequences of returning to the United States

Reestablishing U.S. residency can significantly impact how your income and assets are taxed. You may face changes in:

• The U.S. tax treatment of foreign investments.
• Reporting requirements for foreign bank accounts and retirement plans.
• Eligibility and coordination of social security benefits.
• Coverage under totalization agreements with foreign countries.

Exit tax implications for citizenship renunciation

If you plan to renounce your U.S. citizenship, you may be subject to the exit tax, which applies to certain high-income or high-net-worth individuals. You could owe tax on the unrealized gains of your global assets if:

• Your net worth exceeds the IRS threshold.
• Your average annual income tax liability over the past five years is too high.
• You have not complied with all prior tax filing obligations.

The consequences of renunciation can be severe if done without proper tax planning and professional guidance.

Importance of long-term expat tax planning

Expats with significant assets, foreign business interests, or complex income sources benefit from starting their tax planning early. Strategic preparation can:

• Minimize exposure to the exit tax.
• Optimize the timing of income and asset transfers.
• Reduce the risk of penalties and audit.
• Ensure compliance with both U.S. and international tax laws.

Whether you’re staying abroad permanently or preparing for a major life shift, working with a qualified tax advisor helps you stay ahead of costly surprises.
