How to Change Your Fiscal Address on Portal das Finanças

If you have moved to Portugal, moved house within Portugal or left the country, you need to update your tax address (domicílio fiscal) with Autoridade Tributária e Aduaneira (AT). This guide covers which route applies to you, the deadlines, the documents, the step-by-step process on Portal das Finanças, and what to do afterwards.

Deadlines: 15 or 60 days

If you do not hold a Portuguese Citizen’s Card, AT gives you two deadlines to report a new address: 60 days when the change turns you from a non-resident into a resident, or the other way round, and 15 days in every other case, such as moving house within Portugal.

You count as a Portuguese tax resident if you spend more than 183 days in Portugal, consecutive or not, in any 12-month period starting or ending in the year concerned — or if, on any day of that period, you have a home in Portugal in conditions suggesting you intend to keep and occupy it as your habitual residence.

Missing the deadline can result in fines from Autoridade Tributária. The amount depends on the specific case but generally falls between €75 and €375 for individuals. More importantly, tax notices continue to go to your old address, which can lead to missed deadlines for tax filings and additional penalties.

Tax address vs residency address — what’s the difference

For most Portuguese tax residents, the tax address and residency address are the same — your home address. They become different only in specific cases, such as when you use a fiscal representative’s address as your tax domicile.

Step-by-step: change your address on Portal das Finanças

These steps use the online address form, for foreign nationals without a Citizen’s Card. If you are switching from non-resident to resident, see the next section instead.

1. Gather your documents. Have your NIF, your Portal das Finanças password, your passport or ID document and proof of your new address in Portugal ready, scanned for upload.
2. Log in to Portal das Finanças. Go to portaldasfinancas.gov.pt, choose Iniciar Sessão and log in with your NIF and password.
3. Open the address change form. Go to Todos os Serviços > Dados Cadastrais > Morada > Entregar Pedido de Alteração. Menu names change when the portal is redesigned; if you cannot find this path, search the portal for “morada”.
4. Enter your new address and submit. Type your new Portuguese address (street, number, postcode and locality), attach any document the form asks for, and submit the request.
5. Enter the confirmation code. AT posts a letter with a confirmation code to your new address. The change only takes effect once you enter that code on Portal das Finanças.
6. Check your registered address. Open A minha Área > Posição Integrada > Informação cadastral > Dados Gerais de Identificação and check that the new address is shown. If you need proof, request a certidão de domicílio fiscal.

If the letter does not arrive, contact AT through e-balcão or call the CAT helpline on +351 217 206 707 (working days, 9:00–19:00). AT’s official guidance on the domicílio fiscal is in the Morada (Domicílio Fiscal) section.

Moving from non-resident to resident

The online address form does not cover a foreign national whose registered address is abroad and who is becoming a Portuguese tax resident. Send that request through e-balcão instead — Contactos > Atendimento e-balcão > registar nova questão, then Registo Contribuinte > Identific > Alteração Morada/Singulares — with scanned copies of your documents, or book an appointment at a Serviço de Finanças.

• Non-EU citizens: your passport or ID document, plus your AIMA residence permit (valid on the date of the request), your AIMA appointment proof or the receipt for a pending AIMA application, or an AIMA international or temporary protection document. If your new address differs from the one on the AIMA document, add proof that you asked AIMA to change it and a property deed, rental contract, employment contract or document from a public entity showing the new address.
• EU, EEA, Swiss and Andorran citizens: your ID document or passport, plus your CRUE, or a property deed, rental contract, employment contract or document from a public entity showing your Portuguese address. See CRUE for EU citizens.

Documents must be originals or certified copies, unless they can be checked electronically, and documents in a foreign language need a certified translation.

After you update your tax address — what comes next

• Cancel fiscal representation (optional). If you appointed a fiscal representative when you first applied for NIF Portugal as a non-resident, you can now cancel that fiscal representation. Updating your tax address is the first step — see how to cancel fiscal representation.
• Activate electronic notifications (optional). Once your tax address is updated and you no longer need a representative, activate electronic notifications (NCEPF) through Portal das Finanças. AT then delivers future correspondence to your account instead of by post.
• Update other Portuguese records. Also update your address with social security (Segurança Social, where your NISS is registered), your bank, and your healthcare provider (SNS).

Updating your address with AIMA — for non-EU residents

Non-EU residents with a Título de residência must also keep their address up to date with AIMA (Agência para a Integração, Migrações e Asilo, the migration agency that replaced SEF in 2023). AIMA address updates are done separately from tax address updates — through the AIMA portal or in person at an AIMA office.
