Proving Your Address in Portugal: Americans and Britons

An address in Portugal is proved by a set of papers, not by one document, and the set depends on who is asking. AIMA wants a sworn declaration of your address plus a document that matches how you live in the home (owner, tenant or borrower), while the tax authority checks your identity and residence title and issues its own certificate of tax address.

This guide reflects official pages we read on 18 October 2026. It is not legal advice, and the counter that receives your file decides what it accepts. The most recent day-dated change among the pages is the gov.pt guide on moving house, marked “Atualizado em 04/09/2026” (its footer also carries an older line, “Informação atualizada a 11 de setembro de 2023”), so that is the date of this guide’s information. The tax authority’s leaflet on changing the tax address for foreign citizens is marked only “setembro 2026”. Address proof is one step of the order described in our first month paperwork guide.

What counts as proof of address in Portugal?

It depends on the office. The table lists what each page we read asks for.

For the bank’s own list of documents see our guide to opening a bank account in Portugal.

What does AIMA accept as proof of accommodation?

AIMA’s information FAQ (version 1.0, March 2026) and its notice of 29 November 2025 say the proof of accommodation always includes the applicant’s declaration of honor stating the home address and the legal situation behind the right to use the property. The FAQ names the template: “Minuta Declaração de Alojamento”, on AIMA’s page of forms and templates. The second document depends on your situation.

If you are not named in the lease or loan contract, AIMA says the sworn statement must say that you actually live there, give the land registry description number of the property and the basis on which you live there (lease or loan), and give the full name and NIF or NIPC of the owner who let you have the home. The notice adds that AIMA “will analyse the number of residents declared per accommodation”.

Students have their own cases in the same pages: a lease signed by the school with a certified statement naming each student, a certified statement from the school, or for university residences a certificate from the institution that the student is entitled to accommodation.

Our guide to the AIMA residence permit process places this proof in the full file. If you rent, the lease has to identify you, and our guide to renting a home covers what a Portuguese lease must say.

Does AIMA accept a junta de freguesia residence certificate?

Not as proof of accommodation. AIMA’s FAQ says: “Não são aceites como meio de prova atestados emitidos pelas Juntas de Freguesia”, which means certificates from parish councils are not accepted. Its notice of 29 November 2025 says the same.

That does not make the parish certificate useless for everything, and it is not what AIMA asks for. A regional government body, the CCDR Norte, gave a legal opinion on 24 March 2023 to a parish that asked whether it could certify the residence of a foreigner with no visa. The opinion quotes article 34 of Decree-Law 135/99, under which parish certificates of residence are issued when a member of the parish executive or assembly knows the facts, or when two registered voters of the parish testify, or by another lawful means. It concludes that because a foreigner must hold a valid residence title to reside in Portugal, the parish may ask to see it and should not issue the certificate without it.

The gov.pt service page “Pedir atestado de residência” showed a maintenance notice on 18 October 2026 in the two browsers we used, so we state nothing about who issues the certificate, what it costs or how long it is valid. Ask your junta de freguesia.

How do I get a certificate of my tax address?

The tax authority calls it the certidão de domicílio fiscal. The Portal das Finanças page on addresses says that if you need to prove your address you can obtain it, and that it is available in Portuguese and English. The tax authority’s leaflet on certificates (February 2026) says certificates from the Portal are free and always available, and gives the steps:

1. In the Portal’s search box, type “Certidão de Domicílio Fiscal” and under “Pedir Certidão” click “Aceder”.
2. After logging in, select the type “Domicílio Fiscal (Morada)”.
3. Click “Confirmar”, then “Obter”. The document comes as a PDF.

Each certificate has a validation code. The leaflet says it can be shared with a person or entity by giving your NIF and the code, and that they check it in the Portal under Cidadãos, Serviços, Certidões e Comprovativos, Validar Documento. The certificate shows the address registered with the tax authority, so if that address is wrong or old, change it first (next section). AIMA’s FAQ asks for a certificate dated less than 30 days when you are not named in the lease or loan contract, and for students whose accommodation is shown by a school statement.

The leaflet lists “Residência Fiscal” (tax residence) and “Domicílio Fiscal (Morada)” (tax address) as separate certificates, so ask for the one that proves where you live.

How do I register my address with the tax authority when I arrive?

If you got your NIF as a non-resident, you are registered at an address abroad. The Portal das Finanças page on moving from non-resident to resident says a foreign citizen counts as a tax resident when they stay more than 183 days, consecutive or not, in any 12-month period starting or ending in the year, or stay less but have a home in conditions that suggest an intention to keep and occupy it as a habitual residence. After either test is met you must report your residence in Portugal within 60 days and update your registration. Our guide to the Portuguese NIF covers how the number itself is obtained.

For this change, the Portal says to use the e-balcão, choosing “Registo Contribuinte”, then “Identific”, then “Alteração Morada/Singulares”, or to go to a tax office or Loja do Cidadão by appointment. The other online route (Dados Cadastrais, Morada, Entregar Pedido de Alteração) does not cover a foreigner whose registered address is abroad and who wants to become a resident.

For a third-country national the page asks for the passport and one document that expressly shows the address you want as your tax domicile:

• a residence title valid on the day of the request, issued by the competent authority
• an AIMA document from its registration platforms
• an AIMA appointment document or the receipt of a pending application, such as a first grant or a renewal

If those documents do not show the address, you can add one of: the public deed of purchase of a home, a lease on a home, an employment contract, or a document issued by a public entity. If the address differs from the one on the AIMA documents, you must show that you asked AIMA to change it, with a document showing the address you want at the tax authority.

The leaflet (September 2026) says documents must be originals or certified copies, unless they can be validated electronically, and that foreign-language documents need a certified translation. On certified translations, the leaflet says a notary, a chamber of commerce and industry, a lawyer or a solicitor can certify a translation, and the translation can also be made by the Portuguese consulate in the country where the document was issued, or by that country’s consulate in Portugal.

When you use the Portal, the change takes effect only after you enter the confirmation code sent by letter to the new address. Appointments can be booked in the Portal under Contactos, Atendimento por Marcação, or by phone on (+351) 217 206 707, on working days from 9:00 to 19:00.

How do I change my address after I move house?

Two offices matter most: the tax authority and AIMA.

Tax authority. The Portal das Finanças page and the tax authority’s leaflet (September 2026) give, for people without a Cartão de Cidadão, 60 days when the change turns a resident into a non-resident or the reverse, and 15 days in the other situations. The gov.pt guide on moving house says a person who changed habitual residence has a maximum of 60 days to communicate the new tax domicile. The tax authority’s 15 days covers “the remaining situations”, while the gov.pt guide gives 60 days without that distinction. We found no page that reconciles the two. The tax authority’s own pages give 15 days for the other situations. The guide says foreigners resident in Portugal without a Cartão de Cidadão change the tax domicile on the Portal das Finanças or at a tax office, and that people who hold a Cartão de Cidadão cannot change it at the tax office. A foreign resident who changes address inside Portugal uses the Portal under Dados Cadastrais, Morada, Entregar Pedido de Alteração, or a tax office by appointment, and the confirmation letter works as described above.

AIMA. AIMA’s FAQ says to open the contact form and choose one of two paths. If you have a process in the Renewals Portal, choose the subject “Portal de Renovações” and then “Comunicar/retificar Morada”. If you already hold your residence title and have no process open, choose “Alteração de dados (sem necessidade de agendamento)” and then “Comunicar/retificar morada, sem emissão de novo cartão”. You state the data and attach the required documents. For the Renewals Portal path, AIMA says it updates the record within a maximum of two working days after registration. If you renew, AIMA recommends confirming that the new address already shows in your personal area of the Renewals Portal before paying the payment reference. Our guide to renewing a residence permit covers the portal. The sidebar of AIMA’s notice of 29 November 2025 showed, on 18 October 2026, a notice dated 1 October 2026 that the contact form had been briefly unavailable for a scheduled technical intervention on 2 and 3 October.

Social Security. For a renewal, the FAQ says to check the address registered with Social Security and, if it still shows an address abroad, to report your Portuguese address as soon as possible because it is essential for the file.

Who else should I tell when I change address?

gov.pt’s guide on moving house lists, among others: your employer; insurers; your bank, because new cards and codes go by post and you should bring proof of the new address; water, energy and telecom providers; and the post office for mail forwarding (a CTT counter request that takes on average 3 working days to start). A holder of a Portuguese driving licence without a Cartão de Cidadão must tell the IMT, and a vehicle owner has 60 days after the address is confirmed to update the registration certificate. Our guide to your first year in Portugal covers the rest of the settling in.

Is anything different for Americans and Britons?

None of the pages we read treats Americans and Britons differently. The tax authority’s rules split EU and EEA citizens (Norway, Iceland and Liechtenstein included) from nationals of other countries, and the page also groups Andorra and Switzerland with the EU and EEA citizens. Neither the United States nor the United Kingdom is in those groups, so the tax authority’s lists treat US and UK nationals as third-country nationals. We did not read whether AIMA’s residence document for Britons covered by the Withdrawal Agreement differs. AIMA also runs a separate Brexit page, which we did not read on this point.

What did we read, and what did we not?

We read the pages below on 18 October 2026. The gov.pt service page for the parish residence certificate was under maintenance in both browsers. We did not read the AIMA template “Minuta Declaração de Alojamento” itself, or any bank’s own requirements.
