NIF, fiscal representative and bank account: your first steps
You cannot buy, pay taxes, or set up utilities in Portugal without a NIF. Here is how foreign buyers get one — plus when you need a fiscal representative and a local bank account.
In short. You need a Portuguese NIF (tax number) before you can buy, open a bank account or pay property taxes. It is free from the state and can be obtained remotely through a lawyer or service (typically €79–250) in a few business days, or the same day in person at Finanças. Buyers living outside the EU/EEA must also appoint a fiscal representative once they own property (typically €100–150 a year) unless they sign up for electronic notifications on the Portal das Finanças.
Long before you sign anything, buying in Portugal starts with a small piece of admin: getting a NIF. Almost nothing happens without it — you cannot complete a purchase, open a bank account, sign for utilities, or pay property tax. The good news is that it is straightforward, and you do not have to be in Portugal to arrange it.
What is a NIF?
The NIF (Número de Identificação Fiscal) is your Portuguese tax number — a nine-digit ID issued by the tax authority (Autoridade Tributária, or Finanças). Individuals and companies both have one. For a property buyer it is the single most important number you will hold: it appears on the promissory contract, the deed, the IMT payment, your utility contracts, and your bank account.
Do you need a fiscal representative?
This is where residency matters, and buyers often confuse the two roles.
If you live in the EU or EEA (including Norway, Iceland and Liechtenstein), a fiscal representative is optional. You can obtain and hold a NIF without one.
If you live outside the EU/EEA, you can still get the NIF itself without a representative, but once you have a genuine tax relationship with Portugal — and owning a property counts — you must either appoint a fiscal representative (a Portuguese-resident person or firm who receives tax correspondence on your behalf and makes sure you meet deadlines) or sign up for electronic notifications on the Portal das Finanças (or the ViaCTT electronic mailbox). The electronic option has existed since July 2022 (Decreto-Lei 44/2022); doing neither when required can be fined €75–€7,500. In practice, many non-EU buyers still appoint a representative, or a lawyer or accountant, at the same time they get the NIF, so that someone in Portugal handles letters and deadlines from day one.
These are two different things. Anyone (a lawyer, an agent, a service) can act as your representative to submit the NIF application for you. A fiscal representative is a specific, ongoing tax role required of non-EU taxpayers who have not signed up for electronic notifications. If you appoint one, a budget of roughly €100–€150 a year is typical for the fiscal-representative service.
How to get your NIF
There are two routes.
In person at a Finanças office or a Loja do Cidadão. The government fee is free, you usually need an appointment, and you must be physically in Portugal. If you are already visiting to view properties, this is easy to fold into the trip.
Remotely, through a lawyer or a specialist service acting for you. You sign a power of attorney, send a copy of your passport and proof of your home address, and they file the application. This is how most overseas buyers do it before they ever set foot in the country.
What you need, what it costs, how long it takes
Documents are minimal: a valid passport or national ID, proof of your address abroad (a recent utility bill or bank statement), and — if you use a representative — a signed power of attorney.
Cost: the NIF itself is free from the state. A remote service typically charges somewhere in the region of €79–€250, often bundling twelve months of fiscal representation. Turnaround is usually a few business days remotely, or same-day in person.
Opening a Portuguese bank account
You do not strictly need a Portuguese bank account to buy, but almost every buyer opens one. It is where your deposit and completion funds sit, how a mortgage is serviced, and how you pay IMI, condominium fees and utilities by direct debit.
To open one you will generally need your NIF, your passport, proof of address, and evidence of income or the source of your funds. Some banks let non-residents open an account remotely; others want you present for one short appointment. Opening the account after the NIF, and before you agree a purchase, keeps the later steps smooth.
The right order
For most buyers the sequence is simple: get your NIF (and, if non-EU, appoint a fiscal representative or sign up for Portal das Finanças electronic notifications) → open a Portuguese bank account → then move on to viewings, the promissory contract and the deed. Sorting the admin first means that when you find the right home in Sintra, nothing stands between you and the offer.
Key takeaways
- You need a NIF before you can buy, open a bank account or pay property taxes.
- The NIF is free from the state; a remote service costs about €79–250 and takes a few business days.
- Buyers living outside the EU/EEA must appoint a fiscal representative once they own property (about €100–150 a year) unless they sign up for Portal das Finanças electronic notifications.
- Order: NIF → bank account → offer, CPCV and deed.
Rules and service fees change, and your situation may add wrinkles (joint buyers, companies, trusts). Use a Portuguese lawyer or a reputable NIF/fiscal-representation service, and confirm the current requirements before you pay anyone.
