EU Citizens Moving to Portugal 2026: CRUE, NIF, NISS, SNS

If you hold the nationality of an EU country, of Iceland, Liechtenstein or Norway, of Switzerland or of Andorra, you do not need a visa or a residence permit to live in Portugal. What you do need is a short trail of registrations: one at the town hall (the CRUE), and then the everyday numbers everyone uses here, for tax, social security and health. None of them is chased at the border, which is why people skip them. This guide follows the law on free movement (Lei 37/2006) and what AIMA, the Câmaras, the tax authority, Social Security and the SNS publish, as of September 2026.

Who this applies to

The free-movement law covers citizens of EU member states and, by extension, nationals of the European Economic Area (Iceland, Liechtenstein, Norway) and Switzerland (Lei 37/2006, art. 3); AIMA and the Câmaras also list Andorra. It covers their family members too, whatever their nationality.

Two groups are not on this route. Non-EU citizens moving on their own need a residence visa: see the D7, the D8 or the visa finder. British citizens are no longer EU citizens; those who already lived in Portugal before Brexit have their own status under the UK Withdrawal Agreement, handled by AIMA, and newcomers use the visa routes. See moving to Portugal from the UK.

The first three months and the 30-day window

For the first three months you may live in Portugal with no conditions or formalities beyond a valid ID card or passport (art. 6). If you stay longer, you must register the right of residence within 30 days after those three months have passed (art. 14 n.º 1), so roughly between day 91 and day 120 after you arrive.

Registration is not a formality you can ignore forever: failing to register is an administrative offence with a fine of €400 to €1,500, halved if it was negligence (art. 30). At the same time, the law says that holding the certificate is never a precondition for exercising a right; your status as an EU resident can be proved by other means (art. 21). In practice, though, the tax office and the SNS ask for the CRUE (see below), so it is the document that makes the rest easy.

Conditions for staying longer than three months

To reside beyond three months you must meet one of these (art. 7 n.º 1):

• Work in Portugal, as an employee or self-employed.
• Sufficient resources for yourself and your family, plus health insurance if your own country requires it of Portuguese citizens.
• Study at a recognised public or private school or university, with sufficient resources (shown by a declaration or other proof of your choice) and health insurance on the same terms.
• Be a family member joining or accompanying an EU citizen who meets one of the above.

"Sufficient resources" has no fixed euro amount in the law: they must not be below the level under which Portugal grants social support to its own citizens, taking your personal situation into account (art. 2 f). If you stop working you keep worker status while temporarily unable to work through illness or accident, while involuntarily unemployed and registered with the employment service (IEFP), or during related vocational training (art. 7 n.º 3). EU citizens who came to look for a job cannot be removed while they show they are still looking (art. 9 n.º 4).

At registration you sign a sworn statement that you meet one of the conditions. The Câmara may ask for proof, such as an employment contract, an enrolment certificate or proof of resources, but only in specific cases of reasonable doubt and not systematically (art. 9 n.º 2).

Registering at the Câmara: the CRUE

The Certificado de Registo de Cidadão da União Europeia (CRUE) is issued by the Câmara Municipal of the area where you live (art. 14 n.º 2), not by AIMA. It shows your name, address and registration date and is valid for 5 years, or for your planned stay if shorter (art. 14 n.º 3 and 4).

Documents (law and AIMA): a valid ID card or passport and the sworn statement on your condition, which the service gives you at the desk. Câmaras also check that you live in their area. The Câmara do Porto, for example, accepts one of:

• a certificate of residence (atestado de residência) from your Junta de Freguesia;
• a lease in your name with the tax authority's electronic rent receipt or the "Modelo 2" lease notification;
• a purchase deed or land-registry certificate;
• a tax-domicile certificate (certidão de domicílio fiscal) from the Portal das Finanças.

Porto also notes that you must attend in person when the certificate is issued, that children must be present whatever their age (with both parents, or a notarised power of attorney from the absent one), and that you do not need a Portuguese mobile number. If your landlord will not cooperate, see when the landlord won't sign and proof of address (morada).

How and how long. Most Câmaras work by appointment. In Porto you book through Linha Porto or apply online; at the counter the certificate is issued on the spot, online requests take up to 10 working days and you collect the certificate in person. Other municipalities organise it their own way, so check your Câmara's website before you go.

What it costs

By law these fees cannot exceed what Portuguese citizens pay for their own identity card (art. 29 n.º 4). Figures come from the official fee table, last updated by AIMA on 26 February 2026; confirm at your Câmara.

NIF and a bank account

The NIF (tax number) is needed for almost everything: an employment contract, a lease, a bank account, utilities. You can request it online through the Portal das Finanças e-balcão via a legal representative with a power of attorney, or in person, by appointment, at any tax office or Loja do Cidadão. The number never changes; only your status (non-resident or resident) does.

For people living in the EU, Norway, Iceland or Liechtenstein, appointing a tax representative is optional, even once you own property or sign a work contract here (AT leaflet on NIF for non-residents). Next steps: get your NIF before you move, how long a NIF takes and opening a bank account.

Tax residence: tell Finanças within 60 days

The CRUE and your tax status are two separate registers. You become resident for tax purposes once you have spent more than 183 days in Portugal in any 12-month period, or have a home here in conditions suggesting you intend to keep it as your habitual residence (CIRS art. 16). From then on you have 60 days to tell the tax authority and change your status from non-resident to resident; other address changes must be reported within 15 days.

To switch to resident, an EU, EEA, Swiss or Andorran citizen presents an ID card or passport and the CRUE; a deed, a lease, an employment contract or a document from a public body can also be accepted as proof of address. The switch is requested through the e-balcão ("Registo Contribuinte > Identific > Alteração Morada/Singulares") or at a tax office by appointment, not through the ordinary online address form.

Residents pay IRS on their worldwide income, subject to tax treaties. The former NHR regime is closed and IFICI only covers people who come to do specific qualifying work: see NHR is closed: what is IFICI, IRS rates 2026 and two tax deadlines that catch new residents. This is orientation, not tax advice.

NISS: social security number

You need a NISS to work, to pay contributions as self-employed, or to receive benefits. Foreign citizens request it through an online form on the Segurança Social portal. As an EU, EEA or Swiss citizen you attach your national ID card or passport and a document showing why you need the number, typically an employment contract (translated into Portuguese), your start of self-employed activity, or a declaration from the body that needs it (a school, for instance). If you already have a CRUE, attach it too. Your employer can also request it for you. More in what is NISS and how to get your NISS.

Keep in mind that social-assistance benefits are not available during the first three months of residence, and study grants only after permanent residence, unless you are a worker or a worker's family member (art. 20).

SNS: health number and family doctor

You register with the national health service at your local health centre (centro de saúde) and receive a número de utente. A number can be created on your first contact with the SNS, but to have a complete ("updated") registration, which is what enrolment in primary care and eligibility for a family doctor require, an EU citizen who has stayed more than three months presents the CRUE. It is accepted even after it expires, together with an up-to-date proof of address (ACSS, National User Registry). If you show a European Health Insurance Card from another member state, the SNS bills your care to that country. See SNS número de utente and healthcare in Portugal.

Family members

• Family who are EU citizens register at the Câmara like you and get their own CRUE, showing their ID, proof of the family link, your CRUE and, where relevant, proof that they depend on you (art. 14 n.º 6).
• Family who are not EU citizens (spouse, registered or proven partner, children under 21 or dependent, dependent parents) apply to AIMA for a residence card for family members of an EU citizen, within 30 days after their first three months. They get a certificate of application on the spot, the card is due within 3 months, is valid 5 years and lets them work from day one (arts. 15 and 19). If they need an entry visa, it is free and fast-tracked (art. 4). Details in the residence card for family members of an EU citizen.

This is not family reunification. Reunification is the route for people whose sponsor is a non-EU resident, with waiting periods and income and housing conditions. When the person being joined is an EU citizen, the free-movement route above applies instead. Divorce, the EU citizen's death or departure does not by itself end family members' right of residence (art. 8). Enrolling children at school: enrolling a child in a Portuguese school.

Permanent residence after five years

After 5 consecutive years of legal residence you have a right of permanent residence, no longer tied to work or resources (art. 10). Absences of up to 6 months a year do not break continuity, nor does a single absence of up to 12 months for an important reason such as pregnancy, serious illness, study or a posting abroad. Once acquired, the right is lost only after more than 2 consecutive years away.

The permanent residence certificate is issued by AIMA, not the Câmara. Since 1 July 2026 you request it through AIMA's Renovações portal (replacing the old contact form), with your ID, your CRUE and, if you moved, proof of your new address (a Junta certificate, deed or lease); AIMA calls you in only if it needs biometrics. The law sets a maximum of 15 days once residence is verified (art. 16), while AIMA's page states up to three months. The certificate is optional: the SNS confirms you are not obliged to request it when your CRUE expires, but it is the simplest proof of your status.

Citizenship

Since 19 May 2026 (Lei Orgânica 1/2026), citizens of EU member states can apply for Portuguese nationality after 7 years of legal residence (10 for most other nationalities), with proof of Portuguese language and knowledge of culture, history and civic rights and duties. The law's text names EU member states; if you are from Norway, Iceland, Liechtenstein or Switzerland, check with the IRN which period applies to you. See how long for citizenship and Portuguese A2.

Step by step

• Before or on arrival: NIF, then a bank account; line up a lease or another proof of address.
• If you start work: NISS (you or your employer).
• Day 91 to 120: CRUE at your Câmara; non-EU family members apply to AIMA in the same window.
• With the CRUE: register at the health centre for your número de utente.
• Within 60 days of becoming tax resident: switch your NIF to resident at Finanças.
• Driving: check the rules for your licence in exchanging a driving licence.
• After 5 years: permanent residence certificate from AIMA.

Use the relocation checklist to keep track, and read EU citizens: the paperwork nobody asks for. Choosing where to live? Compare costs in the cost-of-living calculator or start with Porto or Lisbon. Procedures differ slightly between Câmaras; what is described as Porto practice is an example, so confirm locally.
