Digital nomads and tax residency: why no home does not mean no tax

What this covers

A digital nomad is someone who works remotely while moving between countries. The perpetual traveler idea is the belief that staying a short time in each place means no country can tax you. Official rules do not work that way. Residence is decided country by country, some tests need no day count at all, and income from work can be taxed where the work is done whatever your residence.

Test the idea that moving often means paying nowhere

Residence rules attach to more than days. Spain's Agencia Tributaria says a person is resident if the main base of their economic activities or interests is in Spain, even without 183 days there. New Zealand's Inland Revenue says a permanent place of abode in New Zealand is enough on its own, and you do not need to own it. In the UK, the sufficient ties test counts family, accommodation and work ties, so a person with strong UK ties can become resident with fewer days.

Citizenship can matter too. The IRS says US citizens are subject to tax on worldwide income regardless of where they live. A US citizen who never stays long anywhere is still inside the US system. See United States.

The open question is usually not whether any country has a claim. It is which countries do, and in what order.

Run each country's test separately

There is no shared global count. Each country asks its own question about its own territory. Spending a few months each in several places can leave you resident in one, several, or none, depending on the tests and your ties.

Day tests differ in their window. New Zealand counts more than 183 days in any 12-month period. The UAE counts 183 days, or 90 days for some people who meet extra conditions, within 12 consecutive months. Estonia counts at least 183 days over 12 consecutive calendar months. A rolling window can catch days spread across two calendar years.

Keep a day-by-day record with the day ledger. Countries also differ on whether arrival, departure and transit days count.

Remember that work can be taxed where you do it

Residence is one basis for tax. The place where work is done is another. Under Article 15(1) of the OECD Model Tax Convention, salary for employment exercised in another country may be taxed in that country.

Article 15(2) gives an exception only when three conditions are all met. The worker is present in the other country for no more than 183 days in any twelve-month period starting or ending in the fiscal year. The pay comes from an employer that is not resident there. And the pay is not borne by a permanent establishment of the employer there. Each real treaty may differ from the Model, and without a treaty only domestic law applies.

Self-employed income follows other treaty articles and domestic rules. Ask a professional which articles apply to your work.

Know that treaty relief usually needs a residence somewhere

Tax treaties mostly protect residents of the countries that signed them. Article 4(1) of the OECD Model defines a resident as a person liable to tax in a state by reason of domicile, residence, place of management or a similar criterion.

To use a treaty, a country may ask for proof of residence from your home tax authority. HMRC says you can apply for a UK certificate of residence if you are classed as a UK resident and a treaty exists with the other country. Estonia's tax board says a person using treaty relief there must submit a certificate of tax residency confirmed by the foreign tax authority.

A person who cannot show residence in any country may have no certificate to offer when a source country asks for one. Ask a professional what that means for income from each country. See tax residence.

Keep visas and tax residence apart

Remote work and digital nomad visas are immigration permissions. They do not decide tax residence by themselves. Spain's Agencia Tributaria says holding a residence permit or administrative residence is not the same as being tax resident.

The reverse is also true. A person can become tax resident in a country without a long-stay visa if they meet its tax tests, and can stay tax resident in a former home country after a new visa is granted elsewhere. See living base.

Check social security under its own rules

Social security contributions follow rules that differ from income tax. Inside the EU, the European Commission's Your Europe guidance says you are covered by one country at a time. For people working in two or more EU countries, cover follows the country of residence if a substantial part of the work is done there, which it defines as at least 25% of working time or income. Otherwise it looks to the employer's head office or, for the self-employed, the center of interest of their activities.

For US citizens, Publication 54 says self-employment tax still applies to self-employment income excluded from income tax under the foreign earned income exclusion. The IRS says totalization agreements aim to avoid double social security taxes, and exemption from US taxes under one needs a certificate of coverage. See totalization agreement.

Ask whether your work creates questions for your employer

An employee working from another country can raise tax questions for the employer, not just for the employee. Article 5 of the OECD Model defines a permanent establishment as a fixed place of business through which the business of an enterprise is wholly or partly carried on.

The OECD Secretariat's guidance of 21 January 2021 says a home office may be a permanent establishment if it is used on a continuous basis for the enterprise's business and the enterprise has generally required the person to work there. It said teleworking because of COVID-19 public health measures would not usually create one. It also said that once those measures end, the facts and circumstances must be examined again. That guidance reflects the Secretariat's views, and each country may take its own position.

Payroll and employer social security questions can also arise in the country where the work is done. Tell your employer before working from another country, and let its advisers assess the position.

Common misconceptions

Questions to take to a professional

1. For each country I spent time in this year, which residence tests could apply to me?
2. Do I keep a home, family or economic interests anywhere that could make me resident without a day count?
3. Which countries could tax my work income because I worked while physically there?
4. Am I resident anywhere for treaty purposes, and can I get a certificate of residence?
5. Which country's social security system covers me, and do I need a certificate to prove it?
6. Does my working abroad create payroll or permanent establishment questions for my employer or clients?
7. If I am a US citizen, how do the foreign earned income exclusion and self-employment tax apply?
