How to get a Portuguese NIF online from the UK without paying high fees
If you live in Manchester or Margate and need a Portuguese tax number before you can rent a flat in Porto, open a bank account, or start a visa application, the quotes can be a shock. Some agencies charge premium rates for what is a short administrative task. This guide shows how to get a Portuguese NIF online from the UK while keeping the costs down.
Why UK Residents Face Extra Steps for a NIF
I remember sitting at my kitchen table in Bristol with a Lisbon rental listing open in one tab and a letting agent’s email in the other. The agent wanted my NIF before they would book a viewing. A NIF is the número de identificação fiscal, Portugal’s tax identification number. You need it to sign a lease, connect electricity, buy a SIM contract, open most bank accounts, and handle almost any formal dealing with the Portuguese state. Without one, you cannot really start a life there.
For British applicants, the main complication is Brexit. The UK is now outside the EU and EEA, so a UK resident applying for a NIF is treated like any other non-EU applicant. That brings in the fiscal representative, or representante fiscal.
What a Fiscal Representative Actually Does
A fiscal representative is a person or company with a Portuguese tax address who receives official correspondence from the Autoridade Tributária, usually called Finanças, on your behalf. If Finanças sends a letter about a tax return, a fine, or a missing document, it goes to your representative rather than to your home in Leeds. The representative is responsible for passing that information to you.
That is the reason agencies charge for the service, and also the reason you should take the role seriously. Most people only think about getting the number. The ongoing relationship with your representative matters just as much. For a full explanation, see Getting a NIF as a non-EU citizen: The Fiscal Representative requirement explained.
The Real Cost Drivers
Getting a NIF does not cost anything on the Finanças side when you deal with them directly. What you pay for is everything around it:
- The fiscal representative service, which is often charged yearly
- A power of attorney, or procuração, if a lawyer or friend applies on your behalf
- Notarisation and an apostille on that power of attorney, if the person applying requires one
- Courier or postage for sending paper documents
- Any certified translations the representative asks for
Once you see the cost as several separate pieces, you can cut out the ones you do not need. If you also want to understand the social security number you will need later, see NIF and NISS: How to Get Your Portuguese Tax and Social Security Numbers.
Your Four Main Routes From the UK, Compared
There are four realistic ways to get the number. Each one balances cost against speed and your own tolerance for paperwork.
Route One: A Trusted Friend or Relative in Portugal
If you have a cousin in Braga or an old university friend in Cascais who is a Portuguese tax resident, they can apply as your fiscal representative. This is usually the cheapest option, because many friends will do it as a favour. The process typically means they submit your passport copy and proof of UK address, together with their agreement to act as your representative, either through their own Finanças portal access or in person at a Finanças office or Loja do Cidadão.
There is a catch. Your friend takes on a real responsibility. Official letters about you will arrive at their home, and they have to forward them quickly. If a deadline is missed because a letter sat unopened in their hallway, the consequences fall on you. Have an honest conversation with them before you ask. For more on this arrangement, see Can a non-resident friend in Portugal be my fiscal representative?.
Route Two: A Portuguese Lawyer or Solicitador
A lawyer or solicitador can apply for you and usually acts as your fiscal representative too. This route is very reliable and suits people with more complicated situations, such as buying property at the same time. It is often the most expensive, though, and many lawyers ask for a formal power of attorney.
The power of attorney is where hidden costs build up. In the UK you would normally sign it in front of a notary public, and it may then need an apostille from the FCDO Legalisation Office so Portuguese authorities will accept it. Some firms also ask for a certified Portuguese translation. A service such as RushTranslate can produce one if the firm accepts that format, but confirm exactly what they need before you pay for anything.
Route Three: A Digital NIF Service
Online services such as Bordr were set up for exactly this situation. You upload a scan of your passport and proof of address, sign an authorisation electronically, and the service handles the application and the fiscal representation. Many people living abroad choose this option because it avoids notaries and apostilles completely, at least for the NIF itself.
Before you sign up, check three things on the provider’s own page. First, find out whether the fiscal representation is included or charged separately after the first period. Second, check whether there is a fee to remove them as representative once you move to Portugal. Third, see whether they help you get your Senha das Finanças, the password for the tax portal. Prices and package contents change, so always read the current terms rather than relying on someone’s old forum post.
Route Four: Waiting Until You Land
If you are already flying to Portugal, you can walk into a Finanças office or a Loja do Cidadão with your passport and apply in person. Some people do this on a scouting trip. It costs nothing in fees, although you may still need a representative if you give a UK address. Queues can be long, staff may not speak much English, and you have to be there physically, which does not help if a landlord wants your NIF next week.
Side-by-Side Comparison
| Route | Typical Cost Shape | Speed | Paperwork Burden | Best For |
|---|---|---|---|---|
| Friend or relative as representative | Often free or a small thank-you | Depends on your friend’s availability | Low for you, real responsibility for them | People with a reliable contact in Portugal |
| Lawyer or solicitador | Professional fees, often the highest | Usually reliable | Can involve notary, apostille and translation | Property buyers and complex cases |
| Digital NIF service | A set service fee, sometimes with ongoing representation charges | Generally quick | Minimal, often fully online | Most UK residents who need it fast |
| In person in Portugal | No Finanças fee | Same day if all goes well | Travel and queuing | People already visiting Portugal |
Avoiding Expensive Mistakes With the Apostille
This is where many British applicants pay more than they need to. If your chosen route involves a notarised power of attorney, you will probably need an apostille. The apostille is the certificate the FCDO adds to show that a UK public document, including a notarised one, is genuine.
What the FCDO Charges
As of October 2026, the GOV.UK page “Get your document legalised” gives the following fees, charged per document.
| FCDO Service | Fee as of October 2026 | Who Can Use It |
|---|---|---|
| Standard paper apostille | £45 per document, plus courier or postage | Anyone |
| Return courier to a UK address | £6 per 1.5kg | Anyone using the paper service |
| e-Apostille | £35 per document | Anyone, where the document is eligible |
| Next-Day service | £40 per document | Registered businesses only |
| Restricted Urgent service | £100 per document | Registered businesses only |
The fee applies per document, so a power of attorney split into two separate notarised documents means paying twice. Ask your notary to put everything into one document if they can.
How to Keep Apostille Costs Down
Follow these steps in order:
- Ask your representative, lawyer or service whether they need a notarised and apostilled power of attorney at all, as many digital services do not for a NIF application.
- If an apostille is required, ask whether the receiving party will accept an e-Apostille, which as of October 2026 costs £35 instead of £45 for the paper version and avoids courier fees.
- Find a UK notary who can issue documents in a format suitable for the e-Apostille service, since not every notary works this way.
- Combine all the powers you need, such as NIF application, bank account opening and utility contracts, into one power of attorney so you only pay the per-document fee once.
- Do not order a certified translation until the receiving party confirms they need it and tells you which format they accept.
- Keep digital copies of everything, because you may need the same power of attorney again for a lease or bank account.
Watch Out for Middlemen
Some agencies offer to arrange your apostille and add their own margin on top of the FCDO fee. The FCDO’s Next-Day and Restricted Urgent services are only for registered businesses, which is why some intermediaries promote faster processing. If you have time, applying directly through GOV.UK is usually the cheapest way. For the wider picture on legalising documents, see Apostilles and Certified Translations for Portuguese Visas, and keep an eye out for the warning signs described in Immigration Scams in Portugal: Fake Contracts and Appointment Sellers.
A Low-Cost Step-by-Step Plan From the UK
This is the sequence I would follow if I were starting again from my flat in Bristol, with spending kept as low as possible.
Before You Apply
Collect the documents first. You will normally need:
- A clear colour scan of your valid passport, including the photo page
- Recent proof of your UK address, such as a council tax bill, bank statement or utility bill
- A UK phone number and email address you check regularly
- Your full name exactly as it appears on your passport, with no shortened versions
Then decide on your route. If you have a reliable friend in Portugal, ask them first. If not, compare two or three digital services and a local solicitador, and request written quotes that list every element separately: application, first period of representation, renewal of representation, and removal.
Submitting the Application
- Choose your representative and confirm in writing that they will forward all Finanças correspondence promptly.
- Send your passport scan and proof of address through their secure upload system, never as an attachment to an unknown email address.
- Sign the authorisation or power of attorney in the format they request.
- If an apostille is needed, use the cheapest FCDO option that the receiving party will accept.
- Wait for confirmation of your NIF, which usually arrives as a document showing your number, often called a comprovativo.
- Save that document in several places, because landlords, banks and visa consulates will ask for it.
Getting Your Finanças Password
The NIF is only part of the job. To use the Portal das Finanças you need your Senha das Finanças, and it is usually sent by post to the tax address on record. If your representative’s address is listed, the letter will go to them. Ask them in advance to scan it and send it to you as soon as it arrives. For the full activation process, see NIF password (Senha das Finanças): How to request and activate it by mail and The Portuguese Tax Authority Portal (Portal das Finanças).
After the Number Arrives
Once you have the NIF, the next steps usually follow quickly. You may want to open an account with a Portuguese bank, which Opening a Bank Account in Portugal: Best Banks for Foreigners and Expats covers in detail. If you are applying for a residence visa, you will also need suitable health cover. Many UK applicants compare international policies such as Cigna Global with local Portuguese insurers. See Health Insurance for Portuguese Visa Applications before you buy anything.
Ending the Representative Relationship
Once you move to Portugal and have a Portuguese address, you can usually update your tax address and remove the fiscal representative. This is where ongoing representation charges finally stop, so do not delay it. Some services charge to process the removal. Others let you do it yourself through the portal once you have your password. The full process is explained in Changing your NIF address from a foreign country to your Portuguese address.
A quick example of how this works in practice. Sarah, a teacher from Sheffield, needed her NIF quickly to secure a T1 apartment in Arroios. She had no friends in Portugal, so she compared a few online services, chose Bordr because it handled everything without a notary, and had her number in time for the landlord’s deadline. She skipped apostilles and translations completely. When she moved, she updated her address on the portal within her first month, and the representation ended there.
Your situation may be different, but the approach is the same. Separate the costs, pay only for what your chosen route actually needs, use the cheapest official option for any apostille, and plan your exit from fiscal representation from the start.
