Your First Year in Portugal: A Settling-In Guide

Do the residence permit first, then the numbers that hang from it (NIF, NISS, SNS), then the things that need a Portuguese address: the tax address, the health center, the driving licence, electricity, gas and phone. After that the year is mostly about keeping the file alive: tax residence, the annual income tax return and the renewal window.

This guide puts the first year in that order and links to a full guide for each task. It is a map of what Portuguese and British government pages say, read on 18 October 2026, not legal advice. The most recent change among the pages we read is the gov.pt guide on requesting the NIF and the NISS, marked “Atualizado em 02/09/2026”, so 2 September 2026 is the date of this guide’s information. Pages on tax, driving licences, electricity, gas and phone contracts carry no update date of their own, or an older one, and are noted below.

What is the order of tasks in the first year?

No official page gives one checklist for the whole year. The order below follows the dependencies the pages themselves state: the NIF is asked for the SNS cover and the tax file, the address document is asked for by AIMA, the Finanças and the IMT, and the renewal clock runs from the permit.

The first month in detail is in our guide to first month paperwork in Portugal. This guide starts where that one ends.

How do I get the residence permit in the first place?

You enter on a residence visa and then apply to AIMA. Our guide to residence routes to Portugal for Americans and Britons compares the routes, and the visa guides for retirees and passive income (D7) and remote workers (D8) cover two of them in detail. GOV.UK says that to become a resident you should enter on a residence visa and then apply for a residence card after arrival, and that this is a matter for AIMA.

AIMA’s page says the application for a general residence permit is made by appointment, in person (the page adds that an online platform is being rolled out for residence visa holders), with a signed form, and lists the passport, the residence visa, proof of means, a sworn declaration of your address and health cover among the documents. It also says the temporary permit is “válida pelo período de dois anos” from the issue date and renewable “por períodos sucessivos de três anos”. If you are a short-stay visitor rather than a resident, the 90/180 rule explained for Americans and Britons sets how long you may stay.

Britons who lived in Portugal before 1 January 2021 are in a different position. GOV.UK says they have rights under the Withdrawal Agreement and should hold a Withdrawal Agreement residence card, and AIMA runs a Brexit line for it. Our guide to moving to Portugal as a Briton after Brexit explains the split.

Which numbers do I need, and in what order?

gov.pt says the NIF “permite trabalhar, abrir uma conta bancária ou cumprir as obrigações fiscais”. The NISS gives access to social security rights and obligations. Both are free to request. A foreigner with a Portuguese address can ask for the NIF, the NISS and the SNS user number in one request, according to a note on the same page.

For the NIF, a resident shows an identity document or passport and the residence title, and a passport must come with the entry visa. The NISS is requested online. For a person from outside the EU, the page lists the passport, a work visa, a residence authorization and proof of your work situation, and proof of the residence application. Afterwards a registered letter arrives at your address, and the number is collected at a Segurança Social desk, by appointment on the SIGA platform or by phone at 210 548 888 or 300 088 888. Our guide to the Portuguese NIF for Americans and Britons goes through it, and the bank account guide covers what the NIF unlocks next.

The same gov.pt page for migrants on taxes says that after you receive the NIF you should ask for an access password to the Portal das Finanças, using the “Registar-se” option, to see your tax situation. That password is what you will use for the address change and the annual return below.

How do I register for the public health service?

gov.pt says any foreigner with legal residence can get the SNS user number, and that it is given the first time you go to a public health unit, such as a health center or hospital. The number alone does not make the SNS pay for your care. The identity document, the Portuguese NIF, the full address in Portugal and a valid residence authorization must be linked to it, though the law allows cover without them in some cases. You then register at the health center of your area using the number.

Two details from the same page help in the first year. A temporary registration at another health center is possible for up to 12 months if you live for a time in a different municipality, and the original registration resumes automatically afterwards. For emergencies it gives 112, and 808 24 24 24 for the health advice line. The page was updated on 23 June 2026. Our guide to health care access for newcomers covers fees, the UK S1 route and private cover, and the renting guide covers the lease that usually proves your address.

Do I have to tell the tax office my address?

If you have no Cartão de Cidadão, yes. The Portal das Finanças says foreigners and nationals without one must report a change of address within 15 days, or within 60 days when the change moves you between resident and non-resident status. A foreigner resident in Portugal can ask for the change in the Portal under “Dados Cadastrais > Morada > Entregar Pedido de Alteração”, or in person at the tax office with an appointment. Its FAQ says the change takes two steps: you send the new address, then confirm it with the code in the letter the tax authority mails to that address. Until you enter the code, the Portal says the new address has no effect.

Becoming a tax resident has its own page. The Portal says a foreign citizen is considered tax resident in Portugal when they stayed more than 183 days, consecutive or not, in any 12-month period starting or ending in the year, or stayed fewer days (the page says fewer than 180) but had a home, owned or rented, in conditions suggesting an intention to keep it as a habitual residence. Once either test is met, the page says to report the residence within 60 days and update the registration. For a person registered as non-resident, that change is requested through the e-balcão or in person by appointment, with the passport and, for third-country nationals, the residence permit or the AIMA receipt, appointment proof or pending-application document showing the address, plus, where those do not show the address, a purchase deed, lease, employment contract or public-body document.

The Finanças pages do not distinguish between Americans and Britons: both are third-country nationals for the address and residence steps. Your home country is a separate matter. GOV.UK points Britons to its guidance on moving abroad for UK tax and National Insurance and says the UK has a double taxation agreement with Portugal. For Americans, US tax is a separate question, answered in a separate guide that we have not written yet, and this guide states nothing about it because we read no US tax page. The gov.pt migrants page adds that residents file an annual personal income tax return, the Model 3, and pay the annual IUC vehicle tax if they own a vehicle. We did not research the special tax regime for new residents here.

Can I drive on my American or British licence?

The IMT page on foreign licences from OECD and CPLP countries lists, among the countries covered, the United States and the United Kingdom. It says licences are accepted for driving in Portugal “ainda que os condutores sejam residentes” if the issuing country is a party to the Geneva or Vienna traffic conventions or has a bilateral agreement, no more than 15 years have passed since the licence was issued or last renewed, the holder is under 60, the licence is valid, the holder meets Portugal’s minimum age for the category, and the licence is not seized, suspended, expired or revoked. If those conditions hold, driving remains allowed “mesmo após os condutores obterem a residência”.

Exchanging is a choice when the conditions for keeping your foreign licence are met: “Se quiser trocar a carta de condução estrangeira, pode fazê-lo”. The page says the request goes through the “A Minha Carta de Condução” portal, with a medical certificate issued by your doctor and sent electronically to the IMT, an identity document, a residence registration with the municipality if you have no Cartão de Cidadão, a tax domicile certificate from the Finanças if your address is not on your residence document, the passport if your residence document has no photo and signature, the licence, a psychological assessment certificate if you exchange categories C, D or E, and a certificate of authenticity from the issuing authority or consular service. The fee is 30 euros, with a 10% discount online. The page says test exams are not required for the categories exchanged. Exchange is needed to add other categories.

Britons: GOV.UK says that a UK licence holder registered as a resident can drive with the licence until it expires, and that to exchange it you need a check code from the DVLA (for Northern Ireland, the DVA). That reading and the IMT conditions above (age of the licence and of the holder) are not worded the same way; before relying on either, ask the IMT which text it is applying to your licence. Americans: the IMT page gives no state-by-state detail, so ask the IMT if your state matters. Driving licence rules for EU and EEA licences are different and do not apply to either of you.

How do I set up electricity, gas and the phone?

ERSE, the energy regulator, says the electricity market has been fully liberalized since 4 September 2006, and the natural gas market since January 2010. Any consumer can choose a supplier; those who have not chosen are supplied by the supplier of last resort at a regulated transitional tariff. For electricity up to 41.4 kVA of contracted power, and gas up to 10,000 cubic meters a year, the supplier must hand you a contract sheet (ficha contratual) before you sign, summarizing the services, whether there is a lock-in period, additional services, indicative prices, billing frequency and payment methods. Additional services such as insurance are not required to get supply. A contract made by distance can be withdrawn within 14 days without a reason, or 30 days if made at your home. The electricity page was updated on 21 August 2026 and the gas page on 6 March 2025. ERSE offers a price simulator to compare offers.

For internet, TV and phone, ANACOM’s consumer portal says the maximum lock-in period is 24 months, operators must offer plans without a lock-in, and for contracts signed from 14 November 2022 the charge for leaving early cannot exceed the lower of the value of the benefit given in exchange, in proportion to the time left, or 50% of the remaining monthly fees in the first year and 30% in the second, for a first lock-in; the page applies other limits to a renewed lock-in and says the 24 month cap does not apply to contracts only for paying in installments for a physical connection. The operator, not you, must prove you agreed to the lock-in. The monthly invoice must show the end date and the cancellation cost. These pages say nothing that differs for Americans and Britons. For a place to live that you can put on a contract, see the renting guide.

When do I renew, and what comes after the first permit?

gov.pt’s service page says a foreigner with a valid permit, or one expired for less than six months, can request renewal on the AIMA portal. For a temporary residence permit, the request must be made at least 30 days before it expires, and may be made from 90 days before the end date. In-person renewal is by appointment only, and the IRN contacts eligible people to set it. A person whose permit expired more than six months ago must file a new request at an AIMA store. The page, updated on 1 September 2026, warns that it may be out of date and sends readers to the AIMA portal, so check there before you act. GOV.UK adds that you must tell AIMA if your address, email or name change, and that you may need an appointment for a new card.

Longer horizons are covered in their own guides: our guide to Portuguese citizenship for Americans and Britons covers what comes after years of residence, and the residence routes guide covers what happens if you change route.

What did we read, and what did we not?

We read these pages on 18 October 2026: AIMA’s page on the general residence permit and its Brexit page, the gov.pt service page on renewing the residence permit, the gov.pt guides on requesting the NIF and NISS, on health care for migrants and on taxes and social security for migrants, the Portal das Finanças pages on address change and on the change from non-resident to resident and its FAQ on address change, the IMT page on licences from OECD and CPLP countries, the ERSE pages on contracting electricity and gas, ANACOM’s consumer portal page on lock-in periods, and the GOV.UK guide Living in Portugal.

Related guides: working in Portugal as an American or a Briton, U.S. taxes for Americans living in Portugal and the student visa.

We did not read AIMA’s fee table, the IMT pages for EU and EEA licences and for other countries, any IRS or HMRC page, or any page on schools, shipping belongings or the cost of living. Those are separate guides. If a page here differs from what a counter tells you, ask the counter which text it is applying.
