Do Nomads Pay US Taxes? Federal, State, and Foreign Rules

Yes. If you’re a US citizen or resident, nomads pay US taxes on worldwide income regardless of where they sleep each night — whether that’s a van in Utah, an apartment in Lisbon, or a rotating cast of Airbnbs. Citizenship, not location, is what triggers federal filing. On top of that, a state may still consider you a resident, and banking abroad brings its own reporting rules.

Federal Filing Follows You Anywhere

The IRS taxes US citizens and resident aliens on their worldwide income no matter where they live.¹ Remote wages, freelance fees, business profits, dividends, and capital gains all go on Form 1040. You generally have to file if your gross income tops the standard deduction for your filing status. For 2026, that’s $16,100 for single filers and $32,200 for joint filers.²

The self-employment threshold is far lower. If your net self-employment earnings reach $400, you must file, and you owe self-employment tax of 15.3% covering both halves of Social Security (12.4%) and Medicare (2.9%).³⁴ That rate applies whether you’re working from Denver or Bangkok. You can deduct half of the self-employment tax as an adjustment to income; every self-employed filer qualifies.

Nomads whose main place of business sits outside the US on the regular due date get an automatic two-month extension, shifting the filing deadline from April 15 to June 15. Interest still runs on any unpaid tax from April 15 — the extension covers paperwork, not payment.⁵

State Taxes Are the Harder Problem

Federal rules are uniform. State rules are not, and each state writes its own definition of who counts as a resident. For someone rooted in one place, that never matters. For a nomad, it can produce either overlapping tax bills or, with planning, none at all.

Domicile Is Where You Intend to Return

Most states tax you as a resident if you’re domiciled there. Domicile is the single place you consider your permanent home — the place you intend to return to. You can have only one at a time, and it doesn’t shift just because you travel. It shifts when you move somewhere new with the genuine intention of staying.

Auditors look at where your driver’s license is issued, where you’re registered to vote, where you bank, where your vehicle is registered, and where your family lives. A nomad who claims to have left a state while still holding that state’s driver’s license and voter registration will struggle to prove the move. The burden is on you.

The 183-Day Rule Can Override Everything

Many states also apply a statutory residency rule that works independently of domicile. If you keep a place to live in the state — even a room at a relative’s house — and spend more than 183 days there in the year, that state can tax you as a resident regardless of what you call home. The combination of available housing plus physical presence is what triggers it. Nomads who change their mailing address but keep a home base in a high-tax state often get caught here.

No-Income-Tax States

Nine states impose no individual income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Many nomads deliberately establish domicile in one of these. Those states still collect sales tax, property tax, or both, so savings are real but not total. A mailbox in Florida doesn’t make you a Floridian; you need genuine ties — a home or long-term lease, bank accounts, vehicle registration, and a real pattern of spending time there.

Breaking Domicile When You Leave a High-Tax State

New York, California, and similar states don’t concede residency easily. If you’ve been domiciled in one and want to change, updating your address isn’t enough. The break has to be clean and documented.

Sell or vacate the former home. Keeping a furnished residence available for your use is the single biggest red flag in a domicile audit.
Get a new driver’s license and register to vote in the new state. These are the easiest items for auditors to check and they carry outsized weight.
Move your bank accounts and financial advisors. Retaining every financial relationship in the old state suggests you never really left.
Track your days. Keep a nightly log of where you slept. Contemporaneous records are far more persuasive than reconstructed travel histories.
Build ties in the new state. Join organizations, find a doctor, establish a social footprint. Auditors evaluate the whole life, not just where the mail goes.

In a domicile audit, the state presumes you stayed a resident until you prove otherwise. Paperwork wins these fights; assertions don’t.

Tax Home vs. Domicile

Two related concepts confuse nomads, and the distinction matters. Your tax home is generally the city or area of your main place of business. If you don’t have a regular workplace, the IRS may treat wherever you regularly live as your tax home. If you have neither a regular workplace nor a regular residence, the IRS calls you an itinerant, and your tax home follows you around.⁶ Itinerant status has a hard downside: no foreign tax home means no foreign earned income exclusion.

Domicile, by contrast, is the permanent-home concept states use to decide residency, and the IRS considers it when weighing the closer connection exception for non-citizens.

Tax Breaks for Nomads Working Abroad

US citizens abroad have three main provisions to reduce or eliminate federal tax on foreign earnings. All three apply only to earned income — wages, freelance fees, and business profits — not to dividends or capital gains.

Foreign Earned Income Exclusion

The foreign earned income exclusion lets qualifying taxpayers exclude up to $132,900 of foreign earnings from their 2026 return.² The amount adjusts annually. You qualify under one of two tests:

Physical presence test: you were in a foreign country for at least 330 full days during any 12 consecutive months. The days don’t need to be consecutive, and the window doesn’t have to match the calendar year.⁷
Bona fide residence test: you established genuine residency in a foreign country for an uninterrupted period that includes a full tax year. Brief US trips don’t automatically disqualify you, but you must actually live abroad, not just travel there.⁶

The trap that catches many nomads: if your abode remains in the United States, you don’t have a foreign tax home and can’t claim the exclusion. The IRS looks at where your strongest personal and economic ties are, not just where you sleep. A nomad with a US apartment, a stateside spouse, and all financial accounts back home may find the IRS calls the abode domestic, no matter how many months they log overseas.⁶

Foreign Housing Exclusion

On top of the earned income exclusion, you can exclude certain foreign housing costs — rent, utilities, insurance — though not extravagant items like new furniture. The 2026 cap on qualifying housing expenses is $39,870, roughly 30% of the maximum earned income exclusion. A base housing amount (16% of the earned income exclusion maximum, prorated for qualifying days) is subtracted from your actual costs to reach the excludable portion.⁸ The IRS raises the cap for high-cost cities, so the ceiling may be higher depending on where you live.⁹

Foreign Tax Credit

If you pay income tax to a foreign country, the foreign tax credit offsets your US tax by the amount paid abroad.¹⁰ The credit is capped at the share of your US tax that corresponds to foreign-source income, so it can’t wipe out US tax on domestic earnings.¹¹ You can claim either the credit or the exclusion, and many nomads use both on different portions of their income. The credit generally works best when you’re paying meaningful foreign tax; the exclusion works best in low-tax countries.

Reporting Foreign Bank and Investment Accounts

Banking overseas triggers two separate filings. Missing either one carries steep penalties.

FBAR

If the combined value of your foreign financial accounts tops $10,000 at any point in the year, you must file FinCEN Form 114, the Report of Foreign Bank and Financial Accounts. It covers bank accounts, brokerage accounts, mutual funds, and any other financial account held outside the US.¹² The threshold is aggregate across all accounts, not per account.¹³ The FBAR is due April 15 with an automatic extension to October 15 that requires no separate request. Non-willful civil penalties adjust for inflation each year; willful violations carry much higher penalties plus potential criminal liability.

Form 8938

Form 8938 is a separate FATCA requirement. It covers a broader range of assets than the FBAR, including foreign stock held directly, foreign partnership interests, and interests in foreign trusts, but has higher thresholds. Living in the US, you file when foreign financial assets top $50,000 at year-end or $75,000 at any point (doubled for joint filers). Living abroad and meeting the physical presence or bona fide residence test, the thresholds jump to $200,000 at year-end or $300,000 at any time for individuals, and $400,000 or $600,000 for joint filers.¹⁴

The two forms overlap, but neither replaces the other. You may need both. A $60,000 foreign bank account with no other foreign assets means an FBAR (over $10,000) and a Form 8938 (over $50,000 at year-end, if you live stateside).

Social Security When Working Abroad

Self-employed nomads owe US self-employment tax wherever they work, including abroad. If the country you’re in also requires social security contributions, you could pay into two systems at once. The US has totalization agreements with roughly 30 countries — Canada, the United Kingdom, Germany, Japan, Australia, France, and South Korea among them — to prevent that.¹⁵

Under these agreements, you generally pay only into the country where you’re working. Employees sent abroad temporarily (usually up to five years) stay in the US system and get a Certificate of Coverage to prove exemption from the foreign country’s contributions.¹⁶ Self-employed nomads can request the same certificate. Working in a country without a totalization agreement, you may owe social security to both governments with no offset — a real cost when choosing where to base yourself.

Quarterly Estimated Payments

Nomads whose income isn’t subject to employer withholding — most freelancers, contractors, and business owners — need to make quarterly estimated payments or face underpayment penalties. For 2026, payments are due April 15, June 15, September 15, and January 15, 2027.¹⁷

You avoid the penalty if your total payments cover at least 90% of the current year’s tax or 100% of the prior year’s tax, whichever is less. If your prior-year adjusted gross income topped $150,000, the second threshold rises to 110%.¹⁸ For nomads with volatile income, paying 110% of last year’s tax is the simplest way to stay penalty-free, even if it means overpaying and getting a refund.

Records That Hold Up Under Audit

Every strategy in this article depends on your ability to prove what happened. Auditors don’t take your word. Keep, at minimum: where you slept each night (this drives both the 330-day count and state day-counting rules), income by source and location, business expenses with receipts, and foreign tax payments. A simple daily log of city and country is far more credible than a credit-card-statement reconstruction after the fact.

For the foreign earned income exclusion, keep passport and travel records organized. The 330-day count has to be exact; a single miscounted day can void the entire exclusion. For state domicile, save every document showing new ties and severed old ones: lease agreements, utility bills, driver’s license copies, voter registration confirmations, and vehicle registration receipts.
