How to Get Your NIF & NISS in Portugal
This guide walks you through getting the two most essential documents for living, working, and accessing services in Portugal.
Key Steps
- Get your NIF first at a Finanças office, with a fiscal representative if you’re a non-resident.
- Once you have a work contract or are registered as self-employed, apply for your NISS at a Segurança Social office.
1. Understanding Your NIF (Número de Identificação Fiscal)
The NIF, also known as “número de contribuinte”, is your unique nine-digit tax identification number. It is the first and most critical document you’ll need for almost all administrative and financial activities in Portugal.
Why You Need a NIF:
- Opening a bank account.
- Signing a rental contract or buying property.
- Setting up utility services (electricity, water, internet).
- Working or establishing a business.
- Accessing public services, including healthcare.
How to Get Your NIF:
You can get your NIF at any *Finanças* (Tax Authority) office or a *Loja do Cidadão*. The process is usually quick.
- Required Documents: Valid Passport/ID and a Proof of Address from your home country (like a recent utility bill).
- Fiscal Representative: If you are a non-EU/EEA citizen without a Portuguese residence address, you MUST have a fiscal representative (a resident in Portugal) to apply for you.
Pro Tip: Using a specialized service or lawyer to act as your fiscal representative can be the easiest way to get your NIF, especially if you are not yet in Portugal. They can handle the process remotely for a fee.
2. Understanding Your NISS (Número de Identificação de Segurança Social)
The NISS is your unique social security identification number. It is essential for anyone who will be working (as an employee or self-employed) and contributing to the social security system in Portugal.
Why You Need a NISS:
- To be formally employed or register as a self-employed worker.
- To make social security contributions.
- To access social benefits (unemployment, maternity, retirement, etc.).
- For full access to the public healthcare system (SNS).
How to Get Your NISS:
You obtain your NISS from a Social Security (*Segurança Social*) office. It’s highly recommended to book an appointment online first.
- Required Documents: Your Passport/ID, NIF document, Proof of Address in Portugal, and crucially, Proof of Employment (a work contract) or Proof of Self-Employment Activity from Finanças.
Pro Tip for Employees: If you have a work contract, your employer can often handle the NISS application on your behalf. This is the simplest method.
