Digital Nomad Taxes for US Citizens: What's Actually Different

Most countries tax based on residency — leave, stop being a tax resident, stop owing tax there. The United States is one of the only countries in the world that taxes based on citizenship instead. As a US citizen, you generally owe US tax on your worldwide income regardless of where you live or how long you've been gone, unless you formally renounce citizenship. This single fact changes almost every other tax conversation on this site once you're the one reading it.

The main relief mechanism is the Foreign Earned Income Exclusion (FEIE), which lets you exclude a set amount of foreign-earned income from US tax each year if you meet either a physical presence test (330 days outside the US in a 12-month period) or a bona fide residence test. Confirmed for the 2026 tax year: the FEIE cap is $132,900 per qualifying person, up from $130,000 for 2025 — the IRS adjusts this annually for inflation, so expect a similar small increase each year going forward. The alternative is the Foreign Tax Credit (FTC), which credits tax you've already paid to a foreign country against your US bill — generally the better option if you're paying meaningful tax somewhere else, while FEIE tends to help more in low-or-no-tax destinations.

FBAR (Foreign Bank Account Report) is a separate, easy-to-miss requirement: if the combined balance of your foreign financial accounts exceeds $10,000 at any point in the year, you generally have to report it via FinCEN Form 114, even if you owe zero additional tax — this threshold has genuinely remained stable for a long time and is confirmed unchanged for 2026. Penalties for not filing when required can be disproportionate to the actual tax owed, which is why this trips up more nomads than the income tax itself does.

One specific trap worth naming directly: PFIC (Passive Foreign Investment Company) rules apply painful US tax treatment to many foreign mutual funds and investment products — a foreign brokerage account holding local index funds can create a genuinely bad US tax outcome. If you're investing while abroad, this is worth a direct conversation with a US-specialized cross-border tax professional before you buy anything, not after.

None of this changes based on which destination you choose — it applies the same way whether you're in a 0%-tax country like the UAE or a country with its own income tax. See the country-specific spotlights below for how this interacts with a few of the most common destinations.
