The NIF (Número de Identificação Fiscal) is a unique nine-digit tax identification number issued to individuals and legal entities in Portugal. It is essential for identifying taxpayers and is used in many aspects of everyday life.

📌 Why Do You Need a NIF?

The NIF is required for:

• opening a bank account;
• buying or renting property;
• signing a work contract;
• obtaining health insurance or registering with the health system;
• running a business or making financial transactions.

🧾 How to Obtain a NIF in Portugal?

1. In Person in Portugal

EU citizens can apply for a NIF at a local Finanças office or a Loja do Cidadão. You will need to provide:

• a valid passport or national ID card;
• proof of address (e.g. utility bill or bank statement).

Citizens from non-EU countries must also be accompanied by a fiscal representative in Portugal.

2. Online from Abroad

Foreigners living outside Portugal can apply for a NIF remotely through law firms or authorised service providers. You will need to submit:

• a copy of your passport;
• proof of address;
• details of a fiscal representative in Portugal (mandatory for non-residents).

The service usually costs between €100 and €120, and the NIF is issued within 3 to 7 working days.

📄 Required Documents

• valid passport or ID;
• proof of address (e.g. utility bill, bank statement);
• fiscal representative’s details (for non-residents).

❗ Does Having a NIF Mean You Must Pay Taxes?

Getting a NIF does not mean you are automatically subject to taxes in Portugal. Tax obligations only arise when you:

• earn income in Portugal;
• purchase real estate;
• open or manage a business.

Non-residents are required to have a fiscal representative until they become Portuguese tax residents.

✅ Conclusion

Getting a NIF is a crucial first step for anyone planning to live, work, invest or conduct financial activities in Portugal. The process can be done either in person or online depending on your residency status and available documents.
