Working from a beach bar feels like the ultimate tax hack. Unfortunately, your home tax office has never been to that beach bar – and until you give it good reasons, it will happily assume you still live at your old address.
Most nomads who end up with a tax bill didn’t cheat. They just missed one rule. Here are the seven we see most often, with a fix for each. General information as of September 2026, with Germany as the main example because its rules are strict and well-documented – other countries have close cousins of most of these.
Trap 1: the home you kept#
You gave up your job, not your flat. It’s full of your stuff, you “only” stay there a few weeks a year, and the rent is too good to give up.
In Germany, that’s enough. You have a residence wherever you keep a home in circumstances suggesting you’ll keep and use it – no minimum days. Portugal has a similar test: a home held in circumstances suggesting you intend to keep it as your habitual residence. One furnished flat can keep you fully taxable on your worldwide income, however many countries you visit.
The fix: give up the flat, or let it long-term to someone else so it’s no longer available to you. A storage unit is fine; “your room” at your parents’ with your bed in it is not ideal. Deregister where your country has a registration system.
Trap 2: the family you left behind#
Your partner and kids stay home while you “test” nomad life for a year. Tax offices call that your centre of vital interests – and it’s the second question in the tax treaty tie-breaker, right after where you have a permanent home.
Some countries go further. Spain presumes you’re resident if your spouse (not legally separated) and minor children live there permanently. You can rebut it, but the burden is on you.
The fix: if your family stays, assume you stay taxable too, unless an advisor tells you otherwise for your specific case. If you move, move together – or at least make sure your new home base is clearly where your life happens.
Trap 3: the one long stay#
Your travel log shows 150 days here, 120 there. Perfect. Except that winter you spent six and a half months in a flat in Lisbon, straddling New Year.
Many countries look at continuous stays or rolling windows, not calendar-year totals:
- Germany: a continuous stay of more than six months creates a habitual abode, even across two calendar years (holiday-only stays of up to a year excepted).
- Portugal: more than 183 days in any 12-month period beginning or ending in the tax year, and any day with an overnight stay counts.
- Italy: since 2024, more than 183 days of physical presence, counting fractions of days.
Digital nomad visas don’t protect you either. They’re residence permits, not tax exemptions – stay long enough and most make you a regular tax resident. Our digital nomad visa guide covers which programmes have special regimes.
The fix: count the way each country counts, and log every day in our day tracker. For the backstory, read the 183-day myth.
Trap 4: your company follows your laptop#
You’ve moved on, but have you moved your company? Many countries tax a company where its key decisions are actually made – and a fixed place from which you run the business can create a permanent establishment.
The common versions:
- The home-country company run from abroad, which becomes a question for the country you’re sitting in.
- The foreign company run from home, for example a Dubai company managed from a flat in Munich. Germany treats it as managed in Germany and taxes it like a German company.
- The e-Residency misunderstanding. Estonian e-Residency is a digital ID for running a company, not a residence. An Estonian company run entirely from abroad can become taxable elsewhere.
The fix: decide where you live first, then put the company where you are (or where it’s genuinely managed by someone else). Our guides on place of management and setting up a company abroad go into detail.
Trap 5: the exit you never did#
Nomad life often starts softly: a long trip that turns into a longer one. Nobody files an exit, nobody deregisters, and nobody checks whether leaving triggers tax.
That last one matters. Germany taxes unrealized gains on shareholdings of 1% or more when you give up German tax residency after at least seven of the last twelve years – as if you had sold. On a successful GmbH, that can mean a six-figure tax bill on shares you still hold. The good news: on application it can be paid in seven interest-free annual instalments, and it can be waived under conditions if you return within seven years. Other countries, including Canada and France, have their own exit taxes.
The fix: plan the exit before the first flight. Deregistration, final tax return, exit tax check. Leaving Germany? Start with the leaving Germany checklist and the German exit tax guide; for other countries see moving abroad: what happens to your taxes.
Trap 6: the tax that follows you for years#
Even after a clean exit, some countries keep a claim.
- Germany: extended limited tax liability. German citizens who were fully taxable in Germany for at least five of the last ten years and move to a low-tax country (or become resident nowhere) can stay taxable on more of their German-source income for ten years after the year they leave – if they keep substantial economic interests in Germany, such as a German business or large German-source income. It only applies in years when that income exceeds €16,500.
- Spain: the tax-haven quarantine. Spanish nationals who move to a jurisdiction Spain classifies as non-cooperative remain Spanish taxpayers for the year of the move and the following four years.
Notice the German detail: “resident nowhere” can be treated like moving to a low-tax country. Perpetual travel doesn’t dodge this rule; it can trigger it.
The fix: know which of these rules apply to your passport and your old country, and keep your economic ties there modest – or plan for them. The legal side of perpetual travel explains why a real home base usually works better than being nowhere.
Trap 7: the passport that taxes you#
For US citizens and green card holders, none of the above even matters as much, because the US taxes by citizenship: worldwide income, wherever you live, every year.
Relief exists. The Foreign Earned Income Exclusion lets you exclude up to US$132,900 of foreign earned income for 2026 if you meet the physical presence test (330 full days abroad in 12 months) or the bona fide residence test. Foreign tax credits help too. But investment income and company profits are a different story, and reporting comes on top: FBAR for foreign accounts above US$10,000 in aggregate, plus FATCA forms. Penalties for missed forms can exceed the tax.
The fix: as a US person, file every year, wherever you are, and get a US-savvy advisor before setting up any foreign company.
Bonus trap: the bank form#
Every bank asks where you’re tax resident, under the Common Reporting Standard. Write “none” and many banks refuse or close the account. Write your old country and the bank reports your balances there – which contradicts your claim that you left. Write a country where you aren’t really resident and you’ve made a false declaration. Don’t. The honest fix is a real home base. More in banking abroad: why accounts get closed.
The seven traps at a glance#
| Trap | Typical trigger | Fix |
|---|---|---|
| 1. Home you kept | Furnished flat still available | Give it up or let it long-term |
| 2. Family at home | Partner and kids stay | Move together or assume you stay taxable |
| 3. One long stay | Six-plus months in one place | Count like each country counts |
| 4. Company follows laptop | Decisions made where you sit | Company where you live or genuinely managed |
| 5. Exit never done | No deregistration, no exit check | Plan the exit before you leave |
| 6. Tax that follows | Extended liability, quarantine rules | Know your passport’s rules, limit home ties |
| 7. Passport taxes you | US citizenship | File every year, plan structures carefully |
