Digital Nomad Tax Guide: US Citizens Working Remotely Abroad

The rise of remote work has created a new class of mobile worker — the digital nomad — who works for US or UK employers or clients while living across multiple countries. For US citizens, the tax implications of this lifestyle are significantly more complex than for nationals of most other countries, because the US taxes its citizens on worldwide income regardless of where they live or work.

This guide covers the US tax obligations for American digital nomads, the exclusions and credits available to reduce global tax liability, country-specific considerations for popular destinations, vISA and residency tax implications, and the FBAR and FATCA reporting required for offshore accounts and income.

The Core Challenge: US Citizenship-Based Taxation

The United States is one of only two countries in the world (the other being Eritrea) that taxes its citizens on income earned anywhere in the world, regardless of where they live. This means a US digital nomad working from Lisbon, Bali, or Chiang Mai must still file a US federal tax return and potentially pay US tax on all income earned, no matter which country’s soil they are sitting on.

The good news: the US tax code provides significant tools to reduce or eliminate double taxation for Americans working abroad — primarily the Foreign Earned Income Exclusion (FEIE) and the Foreign Tax Credit (FTC). The challenge lies in qualifying for these reliefs and applying them correctly given the complexity of a multi-country lifestyle.

The Foreign Earned Income Exclusion (FEIE)

The FEIE under IRC Section 911 allows qualifying US citizens and resident aliens to exclude a significant amount of foreign earned income from US taxable income. For 2026:

• The FEIE exclusion amount is approximately $130,000 (adjusted annually for inflation from the $126,500 base)
• A housing exclusion or deduction may be claimed on top of this for higher-cost locations
• The income must be foreign earned income — wages, salaries, or self-employment income earned for services performed in a foreign country
• Investment income, US-source income, and retirement distributions are not eligible for exclusion

Qualifying for the FEIE as a Digital Nomad

To claim the FEIE, you must meet one of two tests:

• Bona Fide Residence Test: You must be a bona fide resident of a foreign country for an uninterrupted period that includes an entire calendar year. Establishing bona fide residence requires demonstrating intent to remain in the foreign country indefinitely — not just temporarily. True nomads who move frequently and do not establish a settled home in any one country may struggle to satisfy this test.
• Physical Presence Test: You must be physically present in a foreign country or countries for at least 330 full days in any 12-month period. Days do not need to be consecutive, and you can be in multiple countries. This test is more accessible for nomads and does not require establishing a specific foreign domicile.

The Physical Presence Test is typically easier for digital nomads to satisfy, as it only requires counting days abroad — but meticulous record-keeping of travel dates (passports, boarding passes, hotel receipts) is essential in case of IRS scrutiny.

Self-Employment Tax: The Nomad’s Often-Overlooked Liability

The FEIE excludes foreign earned income from US income tax, but it does not exclude it from US Self-Employment Tax (SE Tax). SE Tax — which covers Social Security (12.4%) and Medicare (2.9%) contributions — applies to net self-employment income of US citizens working abroad, including digital nomads who freelance or operate their own business.

This means a US digital nomad with $100,000 of freelance income who claims the full FEIE (paying zero US income tax) may still owe approximately $14,130 in SE Tax on the net self-employment income. The only exemption is if a Totalization Agreement is in effect with the country where work is performed AND the nomad is also paying into that country’s social security system.

The UK has a Totalization Agreement with the US. A US freelancer who establishes genuine UK residence and pays UK National Insurance contributions may be exempt from US SE Tax on UK work income — but the agreement’s rules on temporary workers, self-employed persons, and territorial coverage must be carefully analysed for each individual situation.

Tax Residency in Country of Residence

In addition to US obligations, digital nomads may become tax resident in their country of work or stay. Most countries determine tax residency by physical presence (typically 183 days or more in a calendar year) and/or by having a “habitual abode” or “centre of vital interests” in the country.

Key residency tax implications:

• UK: The UK uses the Statutory Residence Test (SRT) with multiple tie-breakers. Spending more than 183 days in the UK automatically makes you UK resident for that tax year. Fewer days may still result in UK residence depending on UK ties (UK accommodation, family, UK employment, UK days in prior years).
• EU countries: Most EU countries also apply 183-day rules, with varying tie-breaker provisions. Portugal, Spain (Beckham Law), Georgia, and Cyprus offer preferential tax regimes for digital nomads — but these must be formally applied for and cannot be assumed.
• US tax treaty interaction: Where a bilateral tax treaty exists, the “tie-breaker” provisions in the treaty determine in which country a dual-resident individual is treated as tax resident. This affects which country has primary taxing rights and how the Foreign Tax Credit is applied.

FBAR and FATCA for Digital Nomads

Digital nomads who hold foreign bank accounts — whether for salary receipt, local spending, or client payments — face US reporting obligations:

• FBAR (FinCEN Form 114): Filed annually if the aggregate maximum value of all foreign financial accounts exceeded $10,000 at any point during the year. Due April 15, with automatic extension to October 15.
• Form 8938 (FATCA): Filed with the tax return if specified foreign financial assets exceed the threshold ($200,000 for single filers living abroad on the last day of the year, or $300,000 at any point).
• Foreign bank accounts via fintech: Accounts with Revolut, Wise, N26, Monzo, and similar fintechs may or may not trigger FBAR depending on whether they constitute “foreign financial accounts.” The analysis depends on where the institution is incorporated and whether the account is a deposit account. Professional analysis is recommended.

Digital Nomad Visas: Tax Implications

Many countries now offer specific digital nomad visas allowing remote workers to live legally in the country for one to two years. These visas have varying tax implications:

• Some digital nomad visas (e.g., Portugal D8 visa) explicitly state the holder is subject to local income tax on foreign income after 183 days of residence
• Others (e.g., some Caribbean nations) offer income tax exemptions for visa holders on foreign-sourced income
• Obtaining a digital nomad visa is not by itself a tax residency trigger — actual days present and other tie-breaker criteria also apply
• Paying local income tax on some or all income may provide Foreign Tax Credits that reduce or eliminate US tax liability on the same income

UK-Based US Digital Nomads

For US citizens who are using the UK as their primary base while working remotely — whether for a US employer, UK employer, or as freelancers — the full range of US-UK cross-border tax rules apply. Key points:

• UK income tax (PAYE if employed, Self Assessment if self-employed) applies to UK-sourced income and to worldwide income if UK domicile applies
• The Foreign Earned Income Exclusion can exclude up to approximately $130,000 of UK earnings from US income tax — but not from UK tax or US SE Tax
• The Foreign Tax Credit on UK income tax paid may be a better choice than FEIE if it preserves eligibility for the Additional Child Tax Credit or Earned Income Tax Credit
• US citizens working for US employers in the UK may need their employer to apply for a Certificate of Coverage under the Totalization Agreement to prevent dual NIC/SE Tax contributions

Frequently Asked Questions

Do I still need to file a US tax return if I earn no US-source income as a nomad?

Yes. All US citizens must file Form 1040 if their gross income exceeds the filing threshold ($14,600 for single filers in 2025), regardless of where the income was earned or where they live. The FEIE may reduce or eliminate your US tax liability, but the filing obligation still exists.

Can I use the FEIE if I move between countries throughout the year?

Yes — through the Physical Presence Test. As long as you are physically present in foreign countries (any foreign countries) for at least 330 full days in any 12-month period, you qualify, regardless of how many different countries you visit. The FEIE exclusion amount is then prorated for the specific qualifying period within the tax year.

My employer is a US company and pays me in US dollars. Am I still eligible for FEIE?

Yes — the employer’s nationality and the currency of payment are irrelevant for FEIE purposes. What matters is where the services were physically performed. If you work remotely from abroad for a US employer, the income is foreign earned income (earned in the foreign country) and qualifies for FEIE, provided you meet the bona fide residence or physical presence test.

What records should I keep as a digital nomad?

Maintain: passport entry/exit stamps and pages, boarding passes or flight records, hotel and accommodation receipts, any local work permits or visa documentation, records of foreign tax paid in each country, and bank statements for all foreign accounts. These records support both the FEIE physical presence calculation and any Foreign Tax Credit claims, and protect against IRS challenges to your foreign status.
