What to do if you are an EU citizen and plan to stay for more than 90 days: the Registration Certificate
If your stay is going to exceed three months, you have the legal obligation to register with the Registro Central de Extranjeros (Central Registry of Foreign Nationals). This procedure must be carried out in person at the Oficina de Extranjería (Foreigners’ Office) of the province where you intend to reside or at the corresponding Police Station.
After verifying compliance with the requirements, a Certificado de Registro (a green paper document containing your NIE) will be issued to you immediately. This process formalizes your legal residence for administrative and civil purposes.
Requirements according to Artículo 7 of Real Decreto 240/2007: To obtain this certificate, you must prove that you are in one of these three situations:
-
Work activity: Being an employed or self-employed worker in Spain.
-
Financial self-sufficiency: Having sufficient resources for yourself and your family members so as not to become a burden on social assistance in Spain, as well as public or private health insurance.
-
Students: Being enrolled in a recognized public or private center, having health insurance, and submitting a responsible declaration of possessing sufficient resources.

Important: Failure to carry out this procedure does not imply expulsion, but it can hinder administrative processes such as renting a long-term home or setting up utility contracts.
Does buying your own home in Spain grant you residency?
No, owning your own home in Spain does not automatically grant you residency. If you are a non-EU citizen and buy a house in Spain, you remain subject to the 90-day rule as a tourist. Owning a second home makes it easier to prove accommodation, but it does not change the legal stay periods.
How long can I stay in Spain to work?
If your intention is to carry out a professional activity, the deadlines and requirements change completely depending on your origin.
-
EU citizens: They have no time limit to work. They can do so as self-employed or employed workers under the same conditions as Spaniards. They only need to register if their stay exceeds three months.
-
Non-EU citizens: They need a residency and work authorization.
-
Employed (Cuenta ajena): Generally linked to a prior contract. The initial authorization usually lasts 1 year and is renewable.
-
Self-employed (Cuenta propia): For entrepreneurs. It requires a business plan and financial means.
Is it possible to stay in Spain without working? The non-lucrative residence visa
This is the ideal option for non-EU individuals who wish to live in Spain (for example, retirees or people living on passive income) but are not going to perform any work activity.
The Residencia No Lucrativa (Non-Lucrative Residence) grants an initial authorization of 1 year, which can be renewed for periods of 2 years until reaching long-term residency. The fundamental requirement is to demonstrate possession of sufficient financial means to support oneself without working and to have private health insurance.
This type of visa must be processed at the consulate of the country of residence.
Studying in Spain: how long does the study stay authorization last?
According to Artículo 33 de la Ley Orgánica 4/2000 (Foreigners’ Law), the duration of this authorization is strictly limited to the duration of the training activity. If your goal is to study at Spanish institutions, you should know that, legally, you are not in a situation of “residence,” but of “stay.”
The study stay authorization in Spain has a maximum validity of one academic year, renewable annually for as long as the study or research program lasts. This authorization automatically expires at the end of the course for which it was granted, unless its renewal is processed within the legal deadlines.
Deadlines, extensions, and requirements for students (EU vs. Non-EU)
The procedure for staying legally as a student varies according to your nationality:
-
-
Non-European Union citizens: They must obtain a Visado de Estudios (Student Visa) at their consulate of origin. Once in Spain, if the course lasts more than six months, they must apply for the Tarjeta de Identidad de Extranjero (TIE). According to the Reglamento de la Ley de Extranjería (Real Decreto 557/2011), to extend this stay it is mandatory to prove the successful completion of the previous year’s studies and present a new enrollment.
-
European Union citizens: They do not need a visa or TIE. However, according to Real Decreto 240/2007, if the studies last more than 90 days, they must register in the Registro Central de Extranjeros by providing official enrollment and proving they have health insurance and sufficient financial means.

Key differences between NIE and TIE: which one do I need?
The main difference between the NIE and the TIE is that the TIE serves to prove that we have a residence permit in Spain.
It is essential not to confuse these terms when managing your stay:
-
NIE (Número de Identidad de Extranjero): It is only the administrative identification number. It is given to you for any procedure (buying a house, opening a bank account). It does not grant the right to reside.
-
TIE (Tarjeta de Identidad de Extranjero): It is the physical document that proves you have a legal residence permit in Spain. Non-EU citizens obtain it when their permit is for longer than 6 months.
FAQ: Frequently asked questions about the length of stay in Spain
When do I become a tax resident?
According to the Agencia Tributaria, it is presumed that you are a tax resident if you spend more than 183 days in Spain during the calendar year. However, it also depends on whether your core economic interests or your spouse and children live in Spain.
The end of the Golden Visa: Why is it no longer useful for residency?
As a result of the legislative reforms applied in 2026, the Golden Visa (which allowed obtaining residency by investing €500,000 in real estate) has been eliminated. The objective of this measure has been to curb speculation and facilitate access to housing for local residents. Therefore, real estate investment is no longer a direct way to prolong your stay in Spain.
What happens if I stay in an irregular situation?
Staying beyond 90 days (Non-EU) constitutes a serious infringement of the Ley de Extranjería that can lead to fines of up to €10,000 or expulsion proceedings.
If you are an EU citizen, Spain offers almost total freedom after a simple registration. If you come from outside the Union, planning is key: do not rely on buying a home to obtain papers following the end of the Golden Visa in 2026. Make sure to process your work, study, or non-lucrative residency visa before traveling to avoid legal problems.
