Appointing a Fiscal Representative in Portugal

Last verified: October 2026.

Who this is for

  • You live outside the EU and EEA, hold a Portuguese NIF, and own property, a car, a job, or a business here.
  • You live in Portugal and are moving to a country outside the EU or EEA.
  • You live in the EU or EEA and want to know whether you need a representative (you do not).

Not for you if: you only need a tax number and have no property, job, or business here yet. Read Getting a NIF (Tax Number) in Portugal instead.

A fiscal representative (representante fiscal) is a person or company living in Portugal who receives your tax post and deals with the tax office (Finanças) for you. If you live outside the EU and EEA and have tax dealings in Portugal, the law says you must appoint one. There is a free way out: switch on electronic tax notifications on the Portal das Finanças instead. You have 15 days to do one or the other, and the fine for missing it is €75 to €7,500.

The one exception is a business that charges VAT, which always needs a representative.

What a fiscal representative does

The tax authority (Autoridade Tributária e Aduaneira, or AT) says a representative does three things for you:

  • receives the post that Finanças sends you;
  • meets your tax filing duties, including your income tax returns;
  • uses your rights before Finanças, including complaints and appeals.

As a rule, the representative does not pay your taxes. If you fail to pay your income tax or your IMI property tax, the bill stays yours. The exception is VAT. If you run a self-employed activity that charges VAT, your representative can be jointly liable for that VAT.

Who must appoint one

The test is where you live, not your nationality. The AT explains it in two groups.

You live in the EU, Norway, Iceland, or Liechtenstein. You never have to appoint a representative or switch on electronic notifications. Both are optional. Electronic notifications are still useful, because you can read your Finanças post from anywhere.

You live anywhere else. If you have a tax relationship with Portugal, you must do one of these:

  • appoint a fiscal representative in Portugal; or
  • sign up for electronic notifications on the Portal das Finanças, or for the ViaCTT electronic mailbox run by the post office.

The AT says you have a tax relationship if, for example, you:

  • own a vehicle registered in Portugal;
  • own property in Portugal;
  • have an employment contract for work in Portugal; or
  • run a self-employed activity in Portugal.

Switzerland and the United Kingdom are outside the EU and EEA, so the rule applies to you if you live there.

The rule also covers people who leave. If you live in Portugal and move to a country outside the EU and EEA, the same duty starts when you change your tax address. The law also covers residents who are away for more than six months, unless they go to an EU or EEA country.

You do not need one to get a NIF

The AT's own instructions say you do not need a representative when you first get a NIF as a non-resident living outside the EU and EEA. The duty starts later, once you have a tax relationship, such as buying a flat or signing a job contract.

Some online NIF services sell a year of representation with the number. If you only need the NIF for now, you can decline it. When you later buy property or take a job here, choose between a representative and electronic notifications. See Getting a NIF (Tax Number) in Portugal.

The free alternative: electronic notifications

Since July 2022, the law says the duty to appoint a representative does not apply if you sign up for electronic tax notifications. For most private owners abroad, this is the simplest and cheapest option. It costs nothing.

These channels count:

  • notifications and citations on the Portal das Finanças;
  • ViaCTT, the electronic mailbox run by CTT, the postal service;
  • the public electronic notifications service linked to the single digital address (morada única digital).

To switch on the Portal or ViaCTT channel:

  1. Log in at portaldasfinancas.gov.pt with your NIF and password, or with the Chave Móvel Digital (digital mobile key).
  2. Go to Cidadãos, then Serviços, then A minha área, then Notificações e Citações, then Gerir Canais, then Canais de Notificação.
  3. Choose Ativar (activate) on the channel you want: Portal das Finanças or ViaCTT.

Keep your email and phone number up to date on the portal, so you see when something arrives.

Two warnings:

  • An unread notice still counts. The law treats an electronic notice as delivered after a set period, even if you never open it. For the electronic mailbox, that is 15 days after it is made available. Check your inbox regularly.
  • Cancelling has a condition. If you live outside the EU and EEA and later cancel electronic notifications, the cancellation only takes effect once you have appointed a representative.

If you run a business that charges VAT

If you live outside the EU and EEA and run a self-employed activity in Portugal that is subject to VAT (IVA), electronic notifications are not enough. You must appoint a representative. That representative must also be registered for VAT and resident in Portugal.

The timing is stricter too. You must appoint the representative before your activity starts, when you register it with Finanças. Because the representative can share liability for your VAT, this role usually goes to an accountant.

How long you have

You have 15 days. The AT says the clock starts on the later of these two dates:

  • the day you tell Finanças that your address is abroad; or
  • the day your tax relationship with Portugal begins, for example the day you buy the property.

For a self-employed activity there is no 15-day window. The appointment must come first.

If you got your NIF years ago with a Portuguese address and never changed it, the 15 days have not started. Changing your tax address to a country outside the EU and EEA starts the clock. Make your choice between a representative and electronic notifications on the same day.

Who can be your representative

Any person or company resident in Portugal can act for you. That includes:

  • a friend or relative who lives in Portugal;
  • a foreign citizen who lives here, if they hold a valid residence permit when they accept and are registered as resident with Finanças;
  • a lawyer (advogado), a solicitor (solicitador), or a certified accountant (contabilista certificado);
  • a company registered in Portugal.

The representative must accept the role. An appointment without their express acceptance can be fined like no appointment at all.

How to appoint one on the Portal das Finanças

You and your representative both need a Portal das Finanças password. Then:

  1. Log in and go to Cidadãos, then Serviços, then Dados Cadastrais, then Representante, then Entregar Nomeação.
  2. Choose the scope. Pick IRS (income tax) if you are a private owner or employee. Pick IVA e IRS if you run an activity in Portugal.
  3. Enter the representative's NIF and confirm.
  4. Finanças posts a letter with a confirmation code to the representative.
  5. The representative logs in to their own account, goes to Entregar, then Representação, then Nomeação de representante, chooses Confirmar, enters the code, and clicks Enviar (send).

The appointment is valid once the representative sends the code. If they do nothing, the nomination expires 30 days after you started it, and you must begin again. Warn your representative that the letter is coming.

Other ways to appoint

Through the e-balcão, the online help desk on the Portal das Finanças. Choose Registo de Contribuintes as the area, Identificação as the type of question, and Representação Fiscal as the question.

  • If you file the request yourself, attach a declaration of acceptance signed by your representative.
  • If your representative files it, they attach a power of attorney (procuração) giving them that power.

In person, at any Finanças office or Loja do Cidadão (citizen shop). You and the representative can go together. The representative can also go alone with a power of attorney.

Documents for these routes:

  • a power of attorney or a mandate contract with representation;
  • the representative's tax number and civil identity document;
  • the representative's acceptance.

A power of attorney needs a certified signature, unless it is given to a lawyer or solicitor named as such.

What it costs

Switching on electronic notifications is free. A friend or relative can act for nothing. Professionals charge their own fees, which no law sets. Ask for a written quote, and expect to pay more if you run a VAT activity.

If you miss the deadline

If the law requires you to act and you do neither, the fine is €75 to €7,500.

The bigger problem is that you lose the use of your rights before Finanças until you fix it. That includes complaints, appeals, and court challenges against a tax bill. Notices also keep going to your last known address. People often find out only when a bill has already built up interest.

If you are late, act now. Switch on electronic notifications, or appoint a representative, the same day.

Changing or ending a representation

To replace your representative, run the same nomination on the portal with the new person. It goes through the same letter and code.

If your representative wants to stop, they must tell you in writing at your last address and inform Finanças. Finanças processes it within 90 days, but only if at least a year has passed since the appointment, or you have named someone new. If your representative wants out early, appoint someone else or switch to electronic notifications.

If you move to Portugal or to an EU or EEA country, update your tax address first. The duty then ends. Check your record on the portal (Consultar, then Representantes) and ask Finanças to update it if your old representative still appears.

Practical tips

  • Set up the Chave Móvel Digital, so you can log in from abroad.
  • Switch on electronic notifications even if you also have a representative. You will see what arrives and when.
  • If you own property, check your inbox each April, when the IMI bill is issued.
  • Give your representative a fast way to reach you. A notice they cannot pass on in time still counts as delivered.
