NIF Guides

NIF for non-residents: the complete guide

If you live outside Portugal but your life touches the country, through a property, a bank account, an inheritance or a plan to move, you will be asked for a NIF, the Portuguese tax number. This guide is the complete picture for non-residents: who counts as one, why you need the number, the rules that apply to you, what it costs, and what a NIF does and does not do. For the filing itself, we link to our step by step guide instead of repeating it here.

What a NIF is

NIF stands for Número de Identificação Fiscal, the tax identification number issued by the Autoridade Tributária e Aduaneira, known as Finanças. It has nine digits and it is personal: one number per person, for life. Portugal uses it the way other countries use a national insurance or social security number for tax, except the NIF reaches much further into daily life.

Your NIF goes on property deeds, rental contracts, bank accounts, utility contracts, invoices and visa files. A non-resident NIF is not a different kind of number. It is the same number, registered with an address outside Portugal, or with a fiscal representative address inside Portugal while your own address stays abroad.

Who counts as a non-resident

For tax purposes, you are a non-resident if your tax home is outside Portugal: broadly, you spend fewer than 183 days in Portugal in a 12 month period and you do not keep a permanent home in Portugal that suggests you intend to live there. If either of those flips, you may be a Portuguese tax resident instead, and different duties apply.

Two clarifications matter. First, your nationality is not the test: a Portuguese citizen living in London can be a non-resident, and a British citizen living in Lisbon can be a resident. Second, non-resident for tax is not the same as non-resident for immigration: visa status and tax status are separate questions, answered by different authorities.

This guide is written for the tax non-resident: the person whose life is based abroad but who owns, earns, inherits or plans something in Portugal.

Why non-residents need a NIF

You do not collect a NIF for fun. Specific moments in Portuguese life demand it, and most of them cannot be done in another order:

• Buying property: the deed, the purchase tax and the land registry all record your NIF, and your lawyer or agent will ask for it before you sign anything binding.
• Renting a property out: rental income in Portugal is Portuguese source income. You declare it with a NIF, and your tenant or manager will need the number for the contract and receipts.
• Bank accounts and utilities: Portuguese banks open accounts against a NIF, and electricity, water, internet and phone contracts are issued in the name attached to one.
• Inheriting in Portugal: an estate with Portuguese assets cannot be settled and distributed until the heirs hold NIFs, because the assets are transferred into their names at Finanças.
• Selling assets later: the same number you buy with is the number you sell with, and the sale, and any gain, is recorded against it.
• Remote work and visa paperwork: D7, D8 digital nomad and other residence visa files ask for a NIF early, and employers and clients need it before contracts or invoices.

The legal position, without the fog

Three facts cover most of the law you need. First, the NIF itself is free. Anyone can request one in person at a Finanças office in Portugal, and no fee is charged for the number. What services like ours charge for is the work and the representation around it, not the number.

Second, if you live outside the EU and EEA, you must appoint a fiscal representative resident in Portugal when you register, because Finanças needs a Portuguese address for your official letters. That is a legal requirement, not a sales invention, and our guide to fiscal representatives in Portugal explains the role in full.

Third, if you live inside the EU or EEA, you can usually register using your home address, with representation optional. Since 1 July 2022, EU and EEA taxpayers who activate electronic notifications on the Portal das Finanças can, in eligible cases, rely on those notifications instead of naming a representative at all.

Documents non-residents need

The list is short, and it is the same core list for almost every non-resident:

• A valid passport, in colour, with all four corners visible. EU and EEA citizens can use a national ID card instead.
• Proof of your address abroad, in your name, issued within the last 3 months: a bank statement, a utility bill or an official letter.
• For the remote route, a signed power of attorney for your representative. With our service you sign it online, and it covers only your NIF application and fiscal representation.

Children need a passport, or a birth certificate when they have no passport, plus one parent documents. You can check your exact set in seconds with the free document checklist on our home page.

The two routes, in brief

Route one is in person: travel to Portugal, attend a Finanças office with your documents, and receive your NIF free. If you live outside the EU and EEA, bring the details of your fiscal representative, because the office will ask who holds your Portuguese tax address.

Route two is remote: a representative files for you under power of attorney and your NIF arrives by email. The full walkthrough, with timings and the mistakes that delay people, is in our guide on how to get a Portuguese NIF from outside Portugal, so we will not repeat it here.

What it costs, in the open

In person, the NIF is free, and your only costs are your travel and time. Remotely with GetYourNIF.pt, Standard is €99 per applicant and Urgent is €145 per applicant, VAT included, and both include 6 months of fiscal representation. Fiscal representative renewal after the included 6 months is €99 per year, cancel anytime.

Two optional extras to know about. The Finanças password add-on is €50 per applicant, for people who want their own Portal das Finanças login. Families applying together get 5% off the NIF fees, and the password add-on is never discounted. Every figure is printed in our pricing section before you apply.

What a NIF does not do

Half the confusion around the NIF comes from expecting it to do jobs it never does. Four limits are worth fixing in your mind:

• It never expires. Your number is yours for life, even if you do nothing with it for years.
• It does not make you a tax resident. Residency turns on days spent in Portugal and where your home is, not on holding a number.
• It is not a residence permit or a visa. It gives you no right to live or work in Portugal by itself.
• It does not open a bank account by itself. Banks still run their own checks and ask for their own documents; the NIF is one requirement among several.

After you get your NIF

Three habits keep a non-resident NIF trouble free. Keep your address current: if you move home abroad, update your Finanças record or tell your representative, because letters follow the address on file. Consider the Finanças password if you want to read those letters yourself on the Portal das Finanças; Finanças posts it on paper, which is why it travels slowly.

And know when representation can end. If you move to Portugal and register your own Portuguese address, or you become eligible for electronic notifications, representation can stop. Our guide on when you can stop using a fiscal representative walks through the order of steps, which matters: set the new arrangement up first, then cancel.

Special cases

Buying property jointly. Each buyer needs their own NIF. A property bought by two people is registered against two numbers, and both numbers appear on the deed and the tax records.

Couples and families. Each adult applies individually, and children can hold a NIF too. Filing together as one family application keeps the file together and earns the 5% family discount on NIF fees.

Children. A child NIF is often needed for inheritance, for a family property purchase, or for a family visa file. The documents are the child passport or birth certificate, plus one parent passport and proof of address.

Inheriting property in Portugal. Heirs who live abroad need a NIF before the estate can be transferred into their names. If the estate has tax duties, a representative is usually the practical route for heirs outside the EU and EEA.

Selling a property later. Your sale is recorded against the same NIF, and capital gains paperwork follows the sale. The rates and rules depend on your situation at the time, so take advice on your own facts when you sell rather than relying on general guides, including this one.

Common myths and mistakes

• Myth: you must travel to Portugal to get a NIF. The remote route through a representative exists precisely for people who cannot or do not want to travel.
• Myth: a NIF means Portugal will tax all your income. A NIF is an identifier. Non-residents are generally taxed in Portugal on Portuguese source income, and your wider tax position depends on your own residence and treaties.
• Mistake: using an old proof of address. If the document is older than 3 months, expect the application to stall.
• Mistake: letting representation lapse while you still need it. Missed letters mean missed deadlines, and deadlines in Portugal do not pause because a letter went to the wrong country.
• Mistake: waiting until the week of a property signing or visa appointment. Even the Urgent route needs clean documents first.

This guide is general information about how the NIF works for non-residents. It is not personal tax advice. If your situation involves property, income or an estate in Portugal, take advice on your own facts before you act.
