Required Documents & Obtaining Your NIF (Tax Number)
Unlike other countries, in Portugal absolutely everything (bank account, SIM card, rent) depends on a single document: NIF (Tax Number).
Profile 1: International Student EU/EEA
- Admission Letter: Validated for enrollment and reduced transportation.
- Identity Card / Passport: National Bulletin is accepted. Must be valid on entry date.
- NIF (Tax Number): You can obtain it for free by physically going to the Autoridade Tributária (Finanças). You just need to upload proof of address from your country of origin (bank statement).
- Health Insurance: The European Health Insurance Card (EHIC) is completely sufficient.
Profile 2: Non-EU International Student (Third Countries)
Step 1 is a mandatory immigration file that blocks the next steps.
- Letter of Admission (Matrícula): Must be a full admission to an accredited university.
- Passport: Validity must exceed the requested visa period by at least 3 months.
- NIF with Fiscal Representative: Non-EU students legally need a Portuguese fiscal representative to obtain the NIF before arrival. The backend must integrate a trigger to digital services (e.g. Bordr or e-Residences).
- Strict Proof of Subsistence (Dynamic Calculation 2026):
- The legal benchmark is based on the 2026 gross national minimum wage: €920 / month.
- Minimum funds required for D4 visa: €11,040 / year.
- System validation: Upload bank statement from the last 6 months (accounts in the country of origin require a letter of transferability).
- Criminal record: Apostille of clean criminal record certificate from the country of origin.
Bordr
Is a premium digital service created specifically to help non-EU citizens solve their Portuguese bureaucracy remotely.
What does their NIF package offer?
When a student orders through Bordr, the standard price is $150 USD (excluding VAT) and includes three mandatory services in the package:
1. NIF code generation: Filing documents directly with the Portuguese Tax Authority (Autoridade Tributária).
2. 12 months of Tax Representation: A lawyer or law firm partnered with Bordr assumes the role of legal guarantor in Portugal for one year.
3. Password for Portal das Finanças: Bordr requests the password for the online tax account on behalf of the student and sends it to them via email (a process that usually takes 3-4 weeks, as the password is initially sent by physical mail to the representative’s address).
What does the step-by-step process look like for the student?
Everything is 100% online and takes an average of 7 business days:
1. Payment and Form: The student pays the fee on the Bordr website and fills in their personal details.
2. Easy documents: They only need to upload a color copy of their Passport and a Proof of Address from their country of origin (bank statement or utility bill no more than 3 months old).
3. Power of Attorney: The Bordr system automatically generates a legal power of attorney. The student prints it, signs it by hand, scans it and uploads it back to the platform. This gives the lawyers the right to request the NIF on their behalf.
4. Delivery: The official NIF document comes directly to your email in PDF format.
Critical Aspects that students should keep in mind:
- Renewal fee: Fiscal representation is free for the first 12 months. If the student does not change his address in the system after moving to Portugal, Bordr will automatically charge him an annual renewal fee.
- Solution: The student should be warned that, as soon as he signs his rental contract in Portugal and receives his residence permit, he should go to the Tax Office (Finanças) to change his address to Portugal. Thus, the Bordr service is automatically canceled and free of charge.
e-Residence
Is an option that offers a great budget alternative for non-EU students who want to obtain their TIN with Tax Representation remotely.
Here are the full details of their services, costs
What does their TIN package offer and how much does it cost?
e-Residence’s standard price for a TIN with tax representation included is around €149 (they often have promotions that lower the price to €99 - €129 depending on the season).
Their package includes:
1. TIN Code Generation: Full registration with the Portuguese Tax Authority (Finanças).
2. Basic Tax Representation: The service covers the legal obligation for the first year.
3. Fast Delivery: Standard processing time is 3 to 5 business days
Student Application Process
The process is digitized and optimized for mobile:
- No complex authentication: The student fills out a simple online form.
- Required documents: A clear digital copy of the Passport and a Proof of Address from the country of origin (bank statement, utility bill or driver's license).
- Digital signature: Unlike other platforms where you have to print and scan the Power of Attorney, e-Residence often allows you to sign the document directly on the screen of your phone or laptop, speeding up the process.
Critical Aspects that students should keep in mind:
- Renewal fee: Fiscal representation is free for the first 12 months. If the student does not change his address in the system after moving to Portugal, e-Residence will automatically charge him an annual renewal fee.
- Solution: The student should be warned that, as soon as he signs his rental contract in Portugal and receives his residence permit, he should go to the Tax Office (Finanças) to change his address to Portugal. Thus, the e-Residence service is automatically canceled and free of charge.
Private insurance
Profile 1: EU/EEA Students (Private insurance not mandatory)
For European students, private health insurance is NOT mandatory to enter Portugal, to enrol or to obtain initial residence documents.
- Why is the European Health Insurance Card (EHIC) sufficient? Based on the European Union treaties, the EHIC entitles them to be treated in the Portuguese public system (SNS - Serviço Nacional de Saúde) under exactly the same conditions and at the same costs as a Portuguese citizen.
- Reality trap: Many European students think that the EHIC works as private travel insurance. It is not. The EHIC does not cover private clinics, does not cover elective treatments and does not cover medical repatriation in the event of a serious accident.
- HubStudentsEurope recommendation: For the EU profile, private insurance should be marked as "Optional but recommended for peace of mind".Choose the best insurance with HelloSafe
Profile 2: Non-EU Students (Private insurance is MANDATORY, initially)
This is where the big confusion comes in. For non-EU students, private medical insurance IS MANDATORY in a first phase, being an eliminatory condition for obtaining the D4 visa at the consulate.
- Phase 1: Obtaining the D4 Visa (In the country of origin)
The Portuguese Consulate will never approve the visa file without private medical insurance (travel/international). This must meet strict criteria:
- Have a minimum coverage of 30.000 EUR.
- Explicitly cover medical repatriation and emergency medical assistance.
- Be valid for the entire initial validity period of the visa (usually the first 120 or 180 days of stay).
- Phase 2: Transition to the Public System (After arrival in Portugal)
Once the non-EU student arrives in Portugal and obtains the biometric residence permit from AIMA (formerly SEF), he can go to the Centro de Saúde (Local Health Centre) with his residential address and NIF to obtain a Número de Utente (Public System User Number).
- From that moment on, he has access to the Portuguese public system (SNS).
- Therefore, after obtaining this number, the student can abandon international private insurance, if he wishes, since he is covered by the Portuguese State.
IMPORTANT WARNING: The Portuguese Public Health System (SNS) DOES NOT COVER MEDICAL REPATRIATION! Once you have obtained your residence permit from AIMA and received your SNS user number (Número de Utente), you will have free or very cheap access to public hospitals in Portugal.
However, keep in mind one critical aspect: the Portuguese state will never pay for your medical transport back to your country of origin, nor for repatriation in the event of death. If you completely abandon private insurance, your family will have to bear costs of tens of thousands of euros in extreme emergencies.
HubStudentsEurope RECOMMENDATION: Once you register with the public system (SNS), do not completely cancel any private protection. Use the HelloSafe platform to switch from your initial (more expensive) visa insurance to a basic expat policy or simple accident insurance. This only costs a few euros per month, but it guarantees your repatriation clause and saves you from huge financial risks!
