What the NIF is, and why you need it

Everyone who pays tax in Portugal has a NIF, also called the número de contribuinte (taxpayer number). It identifies you to the Autoridade Tributária (the tax authority) and you will be asked for it constantly in daily life. You can get one even before you move, and having it does not, on its own, make you a tax resident.

You will be asked for it when opening a bank account, signing a lease, buying a SIM card, connecting the electricity, taking a job or opening atividade (registering as self-employed). In short: sort this out first. Once you have it, you can confirm it is well-formed with our NIF validator.

Option A: In person at Finanças

If you are already in Portugal (or visiting), this is the fastest route and it is free. Walk into any Serviço de Finanças (tax office) and you will usually leave with the number the same day.

1
Go to Finanças or a Loja do Cidadão
In larger cities, take a ticket; in small towns you rarely need an appointment.
2
Bring identification
A passport or an EU citizen's ID card. If you want to be registered as a resident, add a valid título de residência (residence permit, non-EU) or the CRUE (EU citizen's registration certificate). Finanças may also ask for proof of address.
3
Leave with the number
It is printed on a slip on the spot. Keep it safe. It never changes.

NOTE · NON-EU RESIDENTS

If you live outside the EU/EEA, you must appoint a representante fiscal (fiscal representative) resident in Portugal until you become resident yourself. Most people use a lawyer or a specialised online service.

Option B: Remotely, before you arrive

Can't travel yet? A lawyer or an online provider can act as your representative and request the NIF on your behalf. You send scans, they handle Finanças.

ANYONE WHO HAS MOVED HERE

Documents you need

In practice, everyone needs identification (a passport or an EU citizen's ID card). If you want to be registered as a tax resident, add a valid título de residência (non-EU) or the CRUE (EU); Finanças may also ask for proof of address. If you apply remotely, you also add a procuração for the representante fiscal. Once you have the NIF, the next step is usually the NISS, your Segurança Social number (see the NISS guide) and, if you are going to work for yourself, opening atividade.

Frequently asked

Does a NIF make me a tax resident?

No. Having a NIF identifies you to Finanças, but it does not by itself make you a tax resident. Tax residency depends on where you live and how long you spend in the country.

How much does a NIF cost?

The number itself is free at Finanças. If you use a lawyer or an online service to request it remotely (especially when you need a representante fiscal), you pay for that service, usually €70–150.

Do I need a representante fiscal?

If you live outside the EU/EEA, yes: you need a representante fiscal (fiscal representative) resident in Portugal until you become resident yourself. EU/EEA citizens do not. It can be someone you know, a lawyer or a specialised service.

What will I need the NIF for?

For almost everything: opening a bank account, signing a lease, buying a SIM, setting up utilities, taking a job, opening atividade (registering as self-employed), buying a home. Get it first.

Does the NIF ever change?

No. It is issued once and is yours for life. Keep it safe. You can confirm a number is well-formed with our NIF validator.
