We submit your application to Autoridade Tributária (AT) and you receive your NIF certificate digitally. Can be done remotely before arriving in Portugal.

NISS requires you to be physically present in Portugal (or provide Portuguese address). We coordinate with Segurança Social after you arrive. You'll receive your NISS card by mail.

Frequently Asked Questions

Can I get a NIF without being in Portugal?

Yes. Our gestores can obtain your NIF remotely using your passport and a Portuguese fiscal representative. You don't need to be physically present in Portugal. Most US citizens get their NIF 2-4 months before traveling to Portugal for their visa appointment.

Do I need a NIF to apply for the D8 visa?

Yes, absolutely. The D8 visa application form requires you to provide your Portuguese NIF. You must obtain your NIF before submitting your visa application at the Portuguese consulate.

Can I get NISS before arriving in Portugal?

Technically possible but uncommon. NISS registration typically requires proof of Portuguese address or physical presence. Most applicants get NISS during their first 1-2 months in Portugal. Unlike NIF, NISS is not required for the D8 visa application.

What's the difference between NIF and NISS?

NIF is your tax identification number (like a US SSN for tax purposes). NISS is your social security number for healthcare and employment. You need NIF for banking, leases, utilities, and taxes. You need NISS for public healthcare (SNS), employment in Portugal, and your residency card.

Can I do this myself for free?

In theory yes, but it's complicated. For NIF, you'd need to either travel to Portugal or appoint a Portuguese fiscal representative (usually €50-150/year). For NISS, you'd need to visit a Segurança Social office in person with translated documents. Our service handles all coordination, saves you time, and ensures correct registration.

Who actually processes my registration?

We coordinate with licensed gestores (for NIF) and accountants (for NISS) who are registered with Portuguese authorities. They submit your applications to Autoridade Tributária (AT) for NIF and Segurança Social for NISS. We handle the coordination and ensure everything is done correctly.

Do NIF and NISS expire?

Your NIF number never expires, but you should update your fiscal address if you move. NISS also doesn't expire, but you need to keep your registration current if you're contributing to Portuguese social security as a self-employed person or employee.
