⚠️ Important: This guide explains how the rules work in general. It is not tax advice. MoveWise is an immigration consultancy, not a tax adviser: before you make any tax decision, speak to a qualified tax adviser (in Spain an asesor fiscal; in Italy a commercialista; in Portugal a contabilista certificado), ideally one used to cross-border cases.

💡 The short answer: No general "digital nomad" tax status exists. Where you pay tax depends mainly on where you are tax resident under each country's own rules, which look at days of presence, your home, your family and economic ties and sometimes your registration. Income can also be taxed where it arises, and some countries, such as the United States, tax their citizens wherever they live. When two countries both claim you, a tax treaty may decide. Moving often does not, by itself, take you outside every tax system.

Key facts for 2026

• Tax treaties based on the OECD Model define a resident as a person liable to tax in a country by reason of domicile, residence or a similar criterion, and settle dual residence with tie-breaker rules (OECD Model, article 4).
• Spain: resident if you spend more than 183 days in Spain in the calendar year, counting sporadic absences, or if your main centre of economic interests is there (AEAT, art. 9 LIRPF).
• Italy: resident if, for most of the tax year, you are present (counting fractions of a day), have your domicile or residence there, or are registered in the population register (art. 2 TUIR).
• Portugal: resident if you stay more than 183 days in any 12-month period starting or ending in the year, or have a home suggesting you intend to keep it as your habitual residence (art. 16 CIRS, Portal das Finanças).
• The United States taxes its citizens on worldwide income wherever they live (IRS).
• Special regimes for newcomers exist in all three countries, each with strict conditions.

This guide is for remote workers and freelancers who move between countries, or who plan to settle in Spain, Italy or Portugal on a digital nomad visa, and want to understand where tax is owed. After reading it, you will know how residence tests work, what tax treaties do, and where to read more about each country.

It was prepared by MoveWise's Legal Managers, who handle digital nomad visa files for Spain, Italy and Portugal every week, from the official texts linked throughout. It does not tell you where you are resident or how to organise your affairs: those answers depend on your facts and belong to a qualified tax adviser.

Why there is no "digital nomad tax status"

A digital nomad visa is an immigration permission: it lets you live in a country while working remotely. It is not a tax category. Tax law in each country asks different questions: are you resident here, and where does your income arise?

So "digital nomad" describes a lifestyle, not a position in tax law. Two people with the same visa can have very different tax situations, depending on how long they stay, where their family lives, where their home is and where they earned their income.

Three ways a country can tax you

Tax systems use three connecting factors, often together:

• ✅ Residence. A resident is usually taxed on worldwide income. This is the rule in Spain, Italy and Portugal.
• ✅ Source. A country can tax income that arises there, such as work physically done there or property located there, even if you are not resident.
• ✅ Citizenship. A few countries also tax their citizens wherever they live; the United States is the best-known example.

Some countries tax residents mainly on local income (often called territorial systems). Which systems touch you depends on your nationality, your home and where your income comes from.

How countries decide you are tax resident

Each country writes its own residence rules. The criteria recur, but the details differ, and one criterion is often enough:

• ✅ Days of presence. The best-known test is more than 183 days, but countries count differently: by calendar year or any 12-month period, full days or fractions of a day, with or without short absences.
• ✅ A home. Having a home available, or one that suggests you intend to live there habitually, can be enough in some countries even with fewer days.
• ✅ Family and economic ties. Where your spouse or partner and children live, or where your main economic interests are, can decide residence.
• ✅ Registration. Some countries attach consequences to being registered as a resident with a municipality.

Being tax resident usually means that country taxes your worldwide income, under its own rules and any treaty that applies. Not being resident usually means it taxes only income that arises there.

The year you move: when residence starts and ends

Countries also differ on how they treat the year of a move:

• Italy generally gives one answer for the whole calendar year: the tests look at "most of the tax period". The Agenzia delle Entrate's Circular 20/E/2024 notes that only some treaties, such as those with Germany, Switzerland and Panama, split the year.
• Portugal, under article 16 of the IRS Code, generally treats you as resident from the first day of your stay once a test is met (from 1 January if you were resident on any day of the previous year), and residence is lost from the last day of presence, with exceptions (for example, if you return the following year).
• Spain applies its tests to the calendar year; how the year of arrival or departure works for you is a question for your adviser.

So the same move can make you resident for a whole year in one country and for part of a year in another. Treaties then decide which country counts for treaty purposes.

Why constant travel does not mean no tax

Many people assume that if they never stay 183 days anywhere, nobody can tax them. That assumption is risky, for four reasons:

1. Days are only one test. A home, family ties or economic interests can make you resident somewhere with far fewer days.
2. Income can be taxed where it arises. Countries generally tax non-residents on income sourced there, for example from work physically performed or property located there.
3. Some countries tax by citizenship. According to the IRS, US citizens and resident aliens are subject to US tax on worldwide income from all sources, wherever they live.
4. Leaving does not always end residence at once. Each country has its own rules on when residence ends, and some keep treating their own nationals as resident in certain cases: Italy and Portugal, for example, have special rules for citizens who move to listed low-tax jurisdictions.

⚠️ Common mistake: Treating "not resident anywhere" as a status you can declare. It is a conclusion that tax authorities may test against your facts, and the burden of proof often falls on you.

When two countries claim you: treaties and tie-breakers

Because each country applies its own rules, you can be resident in two countries in the same year. Double tax treaties exist to deal with this.

Most treaties follow article 4 of the OECD Model Tax Convention, which settles dual residence for individuals with tie-breaker rules applied in this order:

1. The country where you have a permanent home available to you.
2. If you have one in both, the country with which your personal and economic relations are closer: your centre of vital interests.
3. The country where you have a habitual abode.
4. The country of which you are a national.
5. If none of these decides, the two tax authorities settle it by mutual agreement.

Three points to keep in mind. Each treaty has its own wording, and some differ from the Model. A treaty does not apply where none exists between two countries. And the tie-breaker settles residence for the purposes of that treaty; how income is then taxed, and how double taxation is relieved, depends on other articles and on domestic law. All of this is work for a tax adviser who knows both countries.

Salaries and the other 183-day rule

A second "183-day rule" lives in tax treaties and concerns salaries, not residence. Under article 15 of the OECD Model, a salary for work done in another country can generally be taxed there. The exception keeps it taxable only in your country of residence if, broadly, you are present in the work country for no more than 183 days in any 12-month period, your employer is not resident there, and the salary is not borne by a permanent establishment of your employer there. Self-employed income follows other articles.

The two 183-day tests answer different questions, and mixing them up is a common source of error. How they apply to your salary is for a tax adviser.

Social security is a separate question

Social security contributions follow their own rules, not the income tax ones. Within the EU, according to Your Europe, you are generally covered where you work; if you work in several countries, your country of residence covers you when a substantial part of your work (at least 25% of working time and/or income) is done there; posted workers can stay in their home system with a PD A1 form, issued for up to 24 months.

Outside the EU rules, bilateral social security agreements may apply, and some countries have none with each other. Your employer, client contracts and nationality all matter here, so check which system covers you before you start working from a new country.

⚠️ Common mistake: Assuming that paying contributions in one country settles your income tax there, or the reverse. They are two separate questions.

Digital nomad visas and tax residence

Holding a digital nomad visa does not, by itself, make you tax resident. But the Spanish, Italian and Portuguese remote-work visas are residence routes: they are designed for people who move there. Holders who live in the country for most of the year, register locally and move their family there will often meet one or more residence tests.

Before you sign a lease or move your family, ask a qualified tax adviser how the residence rules of the country you are moving to apply to your situation.

Spain, Italy and Portugal at a glance

These short boxes describe each country's residence test as the official sources state it. They are a starting point, not a complete picture.

Spain

According to the Agencia Tributaria (AEAT), article 9 of the personal income tax law (Ley del IRPF) treats you as resident if you spend more than 183 days in Spain in the calendar year, counting sporadic absences unless you prove tax residence in another country, or if the main centre or base of your activities or economic interests is in Spain. Residence is also presumed, unless proven otherwise, if your spouse (not legally separated) and dependent minor children live in Spain.

Spain also has a special regime for people who move there for work, known as the Beckham Law, with strict conditions.

Italy

Since 2024, article 2 of the Italian income tax code (TUIR) treats you as resident if, for most of the tax year (183 days, or 184 in a leap year), you meet one of four tests: physical presence, counting fractions of a day; domicile, meaning the place where your personal and family relationships mainly develop; residence under the Civil Code; or registration in the population register, which is a presumption you can rebut.

Italy also has optional regimes for people who move there, such as the impatriati regime for workers, each with strict conditions.

Portugal

According to article 16 of the Portuguese personal income tax code (Código do IRS), published on the Portal das Finanças, you are resident if you stay in Portugal for more than 183 days, consecutive or not, in any 12-month period starting or ending in the year, or if, having stayed less, you have a home there in conditions suggesting you intend to keep and occupy it as your habitual residence. A day of presence is any day, full or partial, that includes an overnight stay. The law also sets when residence starts and ends within the year.

Portugal has a special regime called IFICI (article 58-A of the Tax Benefits Statute, on the Portal das Finanças). It is not a general regime for remote workers: it is limited to a list of qualified activities, such as higher-education teaching and research, certain qualified jobs in specific companies and startups, and R&D roles.

Keep evidence of where you were

Whatever your situation, residence questions are decided on facts, and facts need evidence. This is process advice, not tax advice:

• ✅ Keep a simple day-by-day log of the countries you were in.
• ✅ Keep boarding passes, tickets and accommodation receipts. Since April 2026 short-stay entries to the Schengen area are recorded digitally rather than stamped, so your passport may not show them.
• ✅ Keep leases, registration certificates and residence permits, with their dates.
• ✅ Keep any certificate of tax residence that a tax authority issues to you: treaty partners and banks often ask for one.

A certificate of tax residence is a document in which a tax authority confirms that you are resident there, often for a specific treaty. In Spain, for example, the Agencia Tributaria issues it online through its electronic office (Certificados, then Censales), with Cl@ve, a digital certificate or an electronic DNI; when possible it is issued immediately, otherwise you can provide evidence of residence. Italy and Portugal issue similar certificates through their tax authorities.

💡 Pro tip: Start the log on the day you leave your current country of residence, not when you first worry about the 183 days. Reconstructing a year of travel afterwards is slow and often incomplete.

A checklist before you move

Answer these questions, then take them to a qualified tax adviser:

1. Where am I tax resident today, and what does that country require to end my residence?
2. Which country will I live in for most of the year, and which tests could it apply to me?
3. Do I keep a home, a partner, children or a registration anywhere else?
4. Where does my income come from: an employer, clients, a company, investments?
5. Does my nationality bring tax obligations of its own?
6. Which social security system will cover me?
7. Is there a tax treaty between the countries involved?
8. What evidence will I keep to show where I lived?

Frequently asked questions

Do digital nomads pay taxes?

Yes, in most cases. No general tax status exists for digital nomads. Where you pay depends on where you are tax resident under each country's rules, where your income arises and, for some nationalities such as US citizens, your citizenship. A qualified tax adviser can map your obligations.

Where do digital nomads pay taxes?

Generally in the country where they are tax resident, and possibly also in countries where income arises. Each country applies its own residence tests, such as days of presence, a home, family and economic ties or registration. If two countries both treat you as resident, a tax treaty between them may decide.

What is the 183-day rule?

It is a common residence test: spending more than about half the year in a country can make you tax resident there. Each country counts differently. Spain uses the calendar year and counts sporadic absences, Italy counts fractions of a day, and Portugal looks at any 12-month period starting or ending in the year. It is rarely the only test.

Can I be tax resident in two countries at once?

Yes, under each country's domestic law. Where the two countries have a tax treaty, its tie-breaker rules, usually based on article 4 of the OECD Model, decide which one counts as your residence for treaty purposes: permanent home, then centre of vital interests, habitual abode and nationality. Applying them is work for a tax adviser.

Does a digital nomad visa make me tax resident?

Not by itself. The visa gives you the right to live in a country; tax residence follows that country's tax tests. Because the Spanish, Italian and Portuguese remote-work visas are residence routes, holders who live there for most of the year often become tax resident. Check your position with an adviser.

If I keep moving and never stay 183 days anywhere, am I outside every tax system?

Not necessarily. Day counts are only one test: a home, family or economic ties, or registration can create residence elsewhere. Countries can also tax income that arises there, some tax their citizens wherever they live, and leaving a country does not always end residence at once. A tax adviser should review your facts.

When does tax residence start in the year I move?

It depends on the country. Italy's tests generally give one answer for the whole calendar year, while Portugal's IRS Code generally treats you as resident from the first day of your stay once a test is met. Some treaties split the year. Ask an adviser how your arrival year is treated.

Do I still pay social security as a digital nomad?

Usually somewhere, yes. Social security follows its own rules: within the EU you are generally covered where you work, with special rules for several countries and for posted workers; elsewhere bilateral agreements may apply. Check which system covers you before you start.

What is a certificate of tax residence?

It is a document in which a tax authority confirms you are resident there, often for a specific treaty. Banks and foreign tax authorities may ask for one. In Spain the Agencia Tributaria issues it online through its electronic office; Italy and Portugal have similar procedures.

Do US citizens pay US tax while living abroad?

According to the IRS, US citizens and resident aliens living abroad are subject to US tax on their worldwide income and must report it. How this interacts with tax in Spain, Italy or Portugal depends on US rules and the relevant treaty, so speak to an adviser who knows both systems.
