Do I need a fiscal representative?

Do I need a fiscal representative in Portugal?

Many people pay €100–300 a year for fiscal representation that, today, is almost always avoidable. Answer three questions and see whether you really need a representative — and what the free alternative is.

    How this works

    This checker decides nothing for you — the final interpretation is always the tax authority's. What it does is cross-check, in your browser, the three things that determine the answer: where you live, whether you have a real tax relationship with Portugal, and whether you already use e-notifications.

    1. 1
      Who is required, in principle
      The law requires a fiscal representative — a person resident in Portugal — from anyone who lives outside the European Union and the European Economic Area and has a tax relationship with Portugal (property, car, open self-employment or income here). That is art. 19 nº6 of the General Tax Law.
    2. 2
      The EU/EEA exception
      If you live in an EU or EEA country (which includes Norway, Iceland and Liechtenstein), appointing one is merely optional (art. 19 nº8). You may have a representative if you want, but you are never obliged to.
    3. 3
      The free route: e-notifications
      Since Decree-Law 44/2022, anyone who subscribes to electronic notifications on the Portal das Finanças (or the ViaCTT digital mailbox) is exempt from appointing a representative (art. 19 nº15). It is free and, for all purposes, replaces a paid representative.
    4. 4
      Dormant NIF vs. active NIF
      The tax authority clarified (Ofício-Circulado 90057/2022) that a non-resident NIF with no obligations or rights to exercise — no property, car, activity or income — does not require a representative. The obligation only arises once there is a genuine tax relationship.
    ATIVAR AS NOTIFICAÇÕES ELETRÓNICAS (GRÁTIS)
    1. Entre no Portal das Finanças com o seu NIF e senha (ou Chave Móvel Digital).
    2. Vá a “A minha área” → “Notificações e Citações” → “Gerir Canais”.
    3. Ative o canal “Notificações e Citações Eletrónicas no Portal das Finanças” (ou adira à ViaCTT).
    4. A partir daí, a designação de representante deixa de ser obrigatória (art. 19.º, n.º 15, LGT).
    NOMEAR OU CANCELAR UM REPRESENTANTE
    1. Nomear: Portal das Finanças → “Todos os serviços” → “Dados Cadastrais” → “Representante” (ou pelo serviço em gov.pt). O representante tem de aceitar no Portal.
    2. Prazo: 15 dias após mudar a morada fiscal para fora da UE/EEE.
    3. Cancelar: primeiro adira às notificações eletrónicas; se vive fora da UE/EEE, o cancelamento só produz efeitos depois disso (art. 19.º, n.º 16).
    4. O representante também pode renunciar por escrito; produz efeitos após comunicação à AT (art. 19.º, n.os 9–10).

    Frequently asked

    Do I need a fiscal representative just to have a NIF?
    It depends on where you live and what the NIF is for. If you live in the EU/EEA, it is never mandatory. If you live in a third country and the NIF stays dormant — no property, no activity, no income in Portugal — the tax authority also does not require a representative (Ofício-Circulado 90057/2022). Once there is a real tax relationship, you need either a representative or to subscribe to e-notifications (free).
    Is a paid representative ever truly required?
    Not for individuals. Since 2022, subscribing to electronic notifications on the Portal das Finanças always dispenses the representative (art. 19 nº15). Firms charging €100–300/year for representation sell a legitimate but avoidable service — the electronic route is free. The only exception in the law is legal persons that cease activity.
    I already have a representative. Am I required to keep them?
    No. You can cancel. The trick is the order: first subscribe to e-notifications, and only then cancel the representation — because, for people living outside the EU/EEA, cancellation only takes effect once an electronic channel is active or a new representative exists (art. 19 nº16). Done in the right order, you stop paying without falling out of compliance.
    I am moving outside the EU/EEA. What must I do?
    Before (or at the same time as) updating your tax address to the third country, turn on e-notifications on the Portal das Finanças or appoint a representative. If you choose a representative, the deadline is 15 days after the address change, and the representative must accept the appointment on the Portal. Ignoring this exposes you to a fine of €75 to €7,500 (art. 124 RGIT).
    I am an Erasmus student — do I need a representative?
    Almost certainly not. If you are an EU/EEA citizen, representation is always optional. If you come from a third country and only got a NIF to open an account or sign contracts, a dormant NIF carries no obligation. The need only appears if you end up living outside the EU/EEA with income or taxable property in Portugal.
