Do I have to pay US taxes if I work overseas?

Every year, thousands of Americans pack their laptops and relocate abroad — to Lisbon, Chiang Mai, Medellín, or Bali — excited about the prospect of working remotely while experiencing the world. Then, usually around February or March, a quiet dread sets in: do I still owe the IRS money even though I haven't set foot in the United States all year? The answer is yes — and understanding exactly why, and what you can do about it, is one of the most important financial skills a location-independent American can develop.

The United States is one of only two countries in the world — the other being Eritrea — that taxes its citizens based on citizenship rather than residency. That means your tax obligation to the IRS does not disappear simply because you moved to another country. Whether you are a salaried employee of a US company working remotely from Berlin, or a freelancer invoicing clients from a beach in Thailand, the IRS wants to hear from you. The good news is that the US tax code contains several powerful mechanisms specifically designed to prevent double taxation for Americans living abroad — but you have to know how to use them.

This guide breaks down the core concepts every US-citizen digital nomad needs to understand: citizenship-based taxation, the Foreign Earned Income Exclusion, the Foreign Tax Credit, state tax obligations that follow you across borders, and the filing deadlines that apply when you are overseas. Think of it as the foundation for every remote work abroad tip you will need on the tax front.

The Citizenship-Based Taxation Rule: Why You Cannot Simply Move Away

Citizenship-based taxation (CBT) is the legal principle that binds a country's tax authority to an individual by virtue of their nationality rather than where they physically live or earn income. For Americans, this principle is codified in the Internal Revenue Code and has been upheld consistently since the Civil War era. The practical consequence is straightforward: if you hold a US passport or green card, you must file a US federal tax return every year your worldwide income exceeds the filing threshold — regardless of where you live.

The filing threshold for 2024 is generally $13,850 for a single filer under 65 (the standard deduction amount). Green card holders — technically Lawful Permanent Residents — are subject to the same rules as citizens. This surprises many people who assumed that surrendering their US address, closing their US bank account, and registering as a resident in another country would sever their IRS obligations. It does not. The only way to permanently exit the US tax system is to formally renounce your citizenship or abandon your green card through the appropriate legal channels — a serious and often costly decision that the vast majority of nomads have no reason to pursue.

It is also worth noting that many countries where digital nomads tend to cluster — Portugal, Spain, Germany, Thailand, Costa Rica — have their own tax residency rules. Spend more than 183 days in most jurisdictions and you may trigger a local tax obligation as well. This is where the risk of genuine double taxation arises, and why the exclusions and credits described below are so important to understand.

The Foreign Earned Income Exclusion: Your Most Powerful Tool

The Foreign Earned Income Exclusion (FEIE) is a provision in the US tax code — specifically Section 911 of the Internal Revenue Code — that allows qualifying Americans living abroad to exclude a substantial portion of their foreign-earned income from US federal income tax. For tax year 2024, the maximum exclusion amount is $126,500 per person. If your foreign earned income falls below this threshold, you may owe zero US federal income tax on that income — though you are still required to file a return and claim the exclusion using Form 2555.

To qualify for the FEIE, you must meet one of two tests. The first is the Bona Fide Residence Test: you must be a bona fide resident of a foreign country for an uninterrupted period that includes an entire tax year. This test is more subjective and involves demonstrating genuine ties to another country — a local lease, integration into the community, intent to remain. The second is the Physical Presence Test: you must be physically present in a foreign country or countries for at least 330 full days during any consecutive 12-month period. Many nomads prefer this test because it is objective and does not require establishing residency anywhere specific. Day counts matter enormously here — a full day means a 24-hour calendar day spent entirely outside the United States.

One critical limitation: the FEIE only covers earned income — wages, salaries, and self-employment income derived from services performed abroad. It does not cover passive income such as dividends, interest, capital gains, rental income, or retirement distributions. If your income includes any of these categories, they remain fully taxable by the IRS regardless of where you live. Additionally, if you use the FEIE, you cannot also contribute to a Roth IRA using that excluded income, since Roth contributions require taxable compensation. This interplay between the FEIE and retirement savings is a nuance that catches many nomads off guard.

The Foreign Tax Credit: When You Are Paying Taxes Abroad Already

The Foreign Tax Credit (FTC) is an alternative — and sometimes complementary — mechanism for avoiding double taxation. Rather than excluding income from US tax, the FTC allows you to offset your US tax liability dollar-for-dollar by the amount of income tax you have already paid to a foreign government. You claim it using Form 1116. If you paid $8,000 in income tax to Germany on the same income, you can generally reduce your US tax bill by $8,000.

The FTC tends to be more advantageous than the FEIE in high-tax countries — places like Germany, France, Sweden, or Australia, where local income tax rates may equal or exceed US rates. In those situations, the FTC can reduce your US liability to near zero while also preserving your ability to make IRA contributions, since your income was not excluded but was merely credited against. In low-tax or no-tax countries — Dubai, the Cayman Islands, or certain digital nomad visa jurisdictions — the FEIE is typically the better tool because there are few or no foreign taxes to credit.

You can use both the FEIE and the FTC in the same tax year, but not on the same income. This means you could exclude a portion of your income using the FEIE and apply the FTC to income that exceeds the exclusion limit or falls into a different category. Coordinating these two tools optimally is genuinely complex, and this is one area where consulting a CPA who specializes in expat taxation — not just any general practitioner — pays for itself many times over.

State Taxes, Filing Deadlines, and FBAR: The Details That Trip People Up

Federal taxes are only part of the picture. Many US states continue to assert tax jurisdiction over former residents who have not clearly established domicile elsewhere. California is the most aggressive: the Franchise Tax Board looks at factors like voter registration, driver's license, professional licenses, and where your family members live to determine whether you remain a California resident for tax purposes. Other notoriously sticky states include New York, Virginia, and South Carolina. If you lived in one of these states before going nomadic, simply moving abroad does not automatically terminate your state tax obligation. You may need to formally establish domicile in a no-income-tax state — Florida, Texas, Nevada, or South Dakota are popular choices among nomads — before departing, or be prepared to continue filing state returns.

On the federal side, Americans abroad receive an automatic two-month extension on their filing deadline — your return is due June 15 instead of April 15, though any taxes owed are still due April 15 to avoid interest charges. You can also request an additional extension to October 15 by filing Form 4868. Separately, if you need until December 15 to meet the Physical Presence Test for the prior year, there is a special extension procedure available as well. Missing these deadlines while owing tax triggers penalties and interest, so calendar management is a genuine remote work abroad tip worth taking seriously.

Finally, the Report of Foreign Bank and Financial Accounts — commonly called FBAR — is a separate filing requirement that many Americans abroad overlook entirely. If the aggregate value of all your foreign financial accounts exceeds $10,000 at any point during the calendar year, you must file FinCEN Form 114 with the Financial Crimes Enforcement Network by April 15 (with automatic extension to October 15). This is not a tax form — it carries no tax — but the penalties for non-compliance are severe: up to $10,000 per violation for non-willful failures, and potentially much higher for willful ones. A related form, Form 8938 (FATCA), applies to higher thresholds but must be filed with your actual tax return. Both forms exist to combat offshore tax evasion and apply to ordinary nomads who simply have a local checking account abroad.

Navigating US taxes as a location-independent professional is genuinely more complicated than filing as a domestic resident — but it is entirely manageable with the right framework. The core principle to internalize is that filing compliance is non-negotiable; the strategic question is which combination of the FEIE, FTC, and tax treaty provisions minimizes your actual liability. Most nomads who take the time to understand these tools discover they owe far less than they feared, and some owe nothing at all on their primary income.

The single best remote work abroad tip on the tax front is this: do not wait until tax season to think about this. The decisions you make in January — where you spend your days, whether you establish foreign residency, which state you call home — determine your options come April. Build your tax strategy into your travel planning from day one, invest in a qualified expat tax professional for your first year abroad, and you will be in a far stronger position than the majority of nomads who treat taxes as an afterthought until a stressful deadline forces the issue.
