Tax residency in Spain: the 183-day criterion and the criterion of economic interests

You are considered a habitual resident of Spain in two cases. First, you stay there for more than 183 days during the calendar year. Second, the main core or basis of your economic activities or interests is located there, directly or indirectly. Only one of these two conditions is required. This is what the Spanish tax authorities state in their practical guide to income tax, under Article 9 of the Personal Income Tax Law.

This page reads this manual and the text of the Franco-Spanish tax treaty. It does not address the tax scale, the formalities for settling in (foreign national number, registration with the registry), or the exact date from which residency begins.

The two criteria

Two points to note. The text refers to the calendar year ("durante el año natural"). And the second criterion is not measured in days: it concerns the location of the core of your activities or economic interests. How the administration assesses this center in practice is not detailed in the pages consulted.

The same two criteria appear in the 2024 declaration manual (page updated on 10/04/2025) and in the 2025 declaration manual (page updated on 17/03/2026).

How are the days counted?

The manual sets out a precise rule regarding absences: occasional absences are counted towards the length of stay, unless the taxpayer proves their tax residency in another country. The text states: "se computarán las ausencias esporádicas, salvo que el contribuyente acredite su residencia fiscal en otro país".

For a French citizen, the consequence is immediate. An absence deemed occasional does not deduct those days from the calculation, as long as you cannot prove your tax residency in another country. The pages consulted do not define what constitutes an "occasional" absence, nor its maximum duration: a trip to France is therefore not automatically considered an occasional absence.

Two other details are included on the page:

• Temporary stays in Spain resulting from obligations undertaken in cultural or humanitarian cooperation agreements with Spanish public administrations are not taken into account (exact conditions can be found in the manual).
• The page reproduces clarifications from the Central Economic and Administrative Court (TEAC). According to them, continuity of service does not depend on the individual's will. The calculation combines days of certified presence, presumed days between two certified presences, and occasional absences, the latter serving primarily to support the conclusion when the threshold has already been reached through actual presence.

The pages consulted do not explain how an arrival or departure day, or a night, is counted. Do not rely on such a rule: ask the administration or a Spanish advisor.

The family: a presumption

The manual adds a presumption. Residence in Spain is presumed, unless proven otherwise, when the legally married spouse and dependent minor children of the taxpayer habitually reside there. The text states: "residan habitualmente en España su cónyuge no séparado legalmente y los hijos menores de edad que dependan de aquel".

If your spouse and minor children live in Spain while you spend less than 183 days there, the text puts you in a position where you have to prove the contrary.

Which autonomous community

Once you are a resident, you are assigned to an autonomous community. The manual applies three criteria, in this order:

1. the community where you spent the most days of the tax period ("mayor número de días del período impositivo"), temporary absences being counted, with a presumption in favour of the place of your usual residence; ;
2. failing that, the one where you obtained the largest part of your IRPF taxable base ("haya obtenido la mayor parte de la base imponible del IRPF"); ;
3. failing that, your last residence declared for IRPF purposes («su última residencia declarada a efectos del IRPF»).

If your residence is presumed based on the presence of your spouse and minor children, you are considered part of the community property regime where they reside. This page of the manual is dated April 10, 2025 (2024 tax return). The pages consulted do not detail how this tax affiliation affects your tax situation.

Resident of both countries: the France-Spain convention

A French citizen who moves to Spain can meet Spanish tax criteria while remaining a tax resident of France. The Franco-Spanish tax treaty (signed in Madrid on October 10, 1995) addresses this situation in Article 4.

Paragraph 1 defines a resident of a State as any person who, under the laws of that State, is liable to tax therein by reason of their domicile (or a similar criterion). Paragraph 2 applies when an individual is a resident of both States. The criteria apply in this order:

1. the permanent residential home; ;
2. if you have one in both States, the center of vital interests, that is to say the State with which your personal and economic ties are closest; ;
3. failing that, the State where you habitually reside; ;
4. failing that, the State of which you are a national; ;
5. If you have the nationality of both States or of neither, the competent authorities will decide by mutual agreement.

The consolidated text consulted does not include a consolidation date. It is necessary to verify the version applicable to the year in question. The subject of French tax residence is addressed on another page of this website.

Tax residency in Spain: a numerical example (fictitious profile)

Situation. A fictional Frenchman moves to Spain in 2027 to work remotely. He spends 170 days there. During the year, he makes four trips to France, each lasting four days. These trips are assumed to be occasional absences as defined by the manual.

Issue. He believes he will remain below the 183-day threshold, since he only counts the days he spends there. Is that correct?

Strategy. He applies the rule in the manual: occasional absences are counted, unless proof of tax residence in another country is provided. He then compares the total to the threshold of more than 183 days.

Result.

Without proof, the threshold is exceeded by 3 days. With proven tax residency in another country, the presence criterion is no longer met, which does not resolve the second criterion or the family presumption. This profile is fictitious: it illustrates the mechanism and does not predict the outcome for your specific situation.

Tax residency in Spain: what changes depending on your situation

• The number of days spent in Spain and the nature of your absences.
• Proof that you have of your tax residence in another country.
• The place where your spouse and minor children live.
• The place where your activities and economic interests are located.
• Your home, your vital interests and your nationality, if you are also a resident of France.
• The autonomous community where you live.

These elements are examined on a case-by-case basis. The rule depends on your situation, which should be verified before making a decision. No tax outcome is guaranteed.
