Fiscal representative in Portugal: who, when you need one, and how much it costs

If you've researched a Portuguese NIF or opened a bank account in Portugal from abroad, you've almost certainly run into the phrase "fiscal representative" — usually without much explanation. Who is this person, what do they do, when is it mandatory, and what does it cost? This guide breaks it down without the legalese.

What it is, in plain terms

A fiscal representative is a natural or legal person with an address in Portugal that you, residing abroad, formally appoint to represent you before the Portuguese Tax Authority (AT).

In practice, this representative:

• Receives correspondence from the AT on your behalf (notifications, summons, clarification requests)
• Has a legal duty to inform you of any relevant communication
• Can be jointly liable for some of your fiscal debts, in specific circumstances

It's not a general proxy — it's an interlocutor exclusively for tax matters. The figure exists because the AT needs someone to deliver notifications to when the taxpayer is not in the country.

When it's mandatory (and when it isn't)

The rule changed in July 2022 with the transposition of Law 119/2019. Previously it was mandatory for any non-resident. Today the rule is:

Where you reside	Fiscal representative required?
Portugal	No. You are your own.
European Union or European Economic Area (includes Norway, Iceland, Liechtenstein)	No — optional since 2022
Outside the EU/EEA	Yes, required by law

EEA = EU + Norway + Iceland + Liechtenstein. Switzerland is not part of the EEA.

Typical cases where it's mandatory (residents outside EU/EEA):

• Brazilians, Angolans, Cape Verdeans
• British citizens (yes, since Brexit the UK counts as a third country)
• US, Canadian, Australian citizens
• Asian citizens (China, India, Philippines, etc.)
• Russians, Ukrainians (non-EU)
• Swiss citizens (Switzerland is not in the EEA)

Cases where you do NOT need one (EU/EEA residents):

• Citizens of Spain, France, Germany, Italy, Poland, Romania...
• Citizens of Norway, Iceland, Liechtenstein
• But: it's still recommended if you don't speak Portuguese or can't regularly check the Tax Portal

What happens if I don't have one when required?

Several possible consequences:

1. Fine — between €75 and €7,500 (for natural persons), applied by the AT
2. Suspension of access to the Tax Portal
3. Blocking of refunds of income tax (IRS) or VAT you may be owed
4. AT notifications considered delivered even if you don't receive them — because you should have had a representative

The last is the most dangerous. If the AT notifies you of a tax debt and you don't respond within 30 days because you have no representative, the debt automatically enters enforcement. Ignorance is not a defence.

Who can be your fiscal representative

The law is relatively open — essentially any person or company with residence or registered office in Portugal can act as representative. Common profiles:

Individuals

• Family or close friends with an address in Portugal
• Portuguese citizen or resident foreigner with an active NIF

Professionals

• Lawyers — registered with the Portuguese Bar Association
• Certified accountants — registered with the Order of Certified Accountants
• Solicitors (solicitadores) — registered with the Order of Solicitors

Companies

• Companies registered in Portugal that offer this service — law firms, accounting offices, specialised digital platforms

The representative doesn't need to be a Portuguese citizen. A foreign citizen residing in Portugal with a NIF can be your representative — as long as they formally accept.

Real 2026 costs

Prices vary widely. For orientation:

Type of representative	Initial price	Annual price (after year 1)
Family / friend	€0 (personal favour)	€0
Individual lawyer	€100 - €200	€80 - €250
Certified accountant	€80 - €150	€60 - €150
Law firm / accounting office	€150 - €400	€120 - €300
Specialised online service	€100 - €150	€0 - €120 (varies)

Note: the Tax Authority charges nothing for appointing or changing a representative. The cost is exclusively what the representative charges for their services.

Most online services (including our NIF request) include free fiscal representation for the first year — it's a standard competitive feature in the market.

What are the risks for the representative?

This part matters if you're thinking of asking someone close to be your representative.

The general rule is that the representative is not liable for your tax debts. Primary liability is always yours, the taxpayer.

But there are exceptions. The representative can be subsidiarily liable if:

1. They failed to inform you of important AT notifications (and you, because of this, missed defence deadlines)
2. They received funds from you to pay taxes and didn't deliver them to the AT
3. They were negligent in managing your fiscal information

In practice, a family member who just receives correspondence and forwards it to you on WhatsApp runs no real risk. What creates liability is acting with gross negligence or bad faith.

Professionals (lawyers, accountants) cover this with professional civil liability insurance, which partly justifies the higher price.

How to appoint or change a fiscal representative

Three paths:

1. Tax Portal (online)

If you already have Portal access:

1. Log in at portaldasfinancas.gov.pt
2. Cidadãos > Serviços > Dados Pessoais Relevantes > Comunicar > Alterar Morada / Representante Fiscal
3. Indicate the new representative's NIF and name
4. Submit

The representative receives a notification to formally accept. Without acceptance, the appointment remains pending and is considered nonexistent.

2. In person at a Tax Office

You bring a completed form + ID + signed acceptance declaration from the representative. Useful if you don't have Portal access.

3. Through the representative themselves

If the representative is a professional (lawyer or accountant), they handle everything through their professional channels. You only need to sign a power of attorney or authorisation.

Changing your fiscal representative

You can change at any time. Common reasons:

• Country move — you now reside in a different country and want a closer representative
• Issues with the current one — unresponsive, slow, or no longer trusted
• Relationship change — separation, end of contract with company, etc.

The change is free with the AT. You only need to:

1. Appoint a new representative
2. Notify the previous one (good practice, although not legally required)

Frequently asked questions

Can I be my own fiscal representative?

Only if you reside in Portugal. If you live abroad, no — it must be someone with a Portuguese address.

Does my fiscal representative have access to my banking data?

No. The representative only receives correspondence from the AT. They have no access to your bank account, salaries, or other non-fiscal financial data. The AT can share fiscal data (income tax returns, VAT, etc.) with the representative because that's part of the role.

If I move to another EU country, do I still need one?

No — if you reside in any EU/EEA country, it's no longer mandatory. But it remains recommended if you can't regularly monitor the Tax Portal.

What happens if my representative dies or becomes incapacitated?

The AT is notified (usually by the heirs) and you have 60 days to appoint a new representative. If you don't, you fall into an irregular situation.

Can I have two representatives?

No. Only one fiscal representative per taxpayer.

Is a fiscal representative the same as having a power of attorney?

No. A general power of attorney grants broad powers (sign contracts, open accounts, buy property). Fiscal representation is specific to the relationship with the Tax Authority — much more limited.

Can I revoke representation at any time?

Yes. Revocation is unilateral — you don't need the representative's consent. But until you appoint a new representative (if still mandatory in your case), you'll be in an irregular situation.

Do foreign companies selling in Portugal need a fiscal representative?

Yes, if the company is non-resident for fiscal purposes in Portugal and has activity here (sales, property, etc.). The rules are similar but with nuances for legal persons — worth consulting a specialist in these cases.

In summary

Fiscal representative in Portugal:

• Mandatory if you reside outside the EU/EEA
• Optional if you reside in the EU/EEA, but recommended
• Costs between €0 (family) and €400 (law firm)
• No major risk for the representative in normal cases
• Can be changed at any time
