The NIF (Número de Identificação Fiscal) is the 9-digit tax ID that everything in Portugal hangs off - opening a bank account, signing a rental contract, getting electricity, registering as a freelancer, even buying a SIM card with NIF for VAT receipts.

After you have a NIF, the next step is getting access to Portal das Finanças (the AT online services), which means requesting a senha (password). This guide walks through both, with paths for EU residents, non-EU residents, and edge cases.

Two scenarios

You areNIF process
EU/EEA citizen living in PTWalk into any AT office (Loja de Cidadão or Repartição de Finanças) with passport + proof of address. Free or €10.20.
Non-EU citizenSame office but MUST appoint a fiscal representative (representante fiscal) - someone PT-resident who agrees to receive mail on your behalf. Fee €10.20.

The fiscal representative requirement (for non-EU/non-EEA residents who are not yet PT residents themselves) is the most common stumbling block. We cover the workarounds below.

Path A - EU/EEA citizen, in Portugal

Bring documents

Required:

  • Passport or EU national ID card
  • Proof of address in Portugal (rental contract, utility bill, atestado de residência from the junta de freguesia)
  • Optional: Cartão de cidadão if you have one - speeds things up

No appointment needed for first NIF request, but check the office’s hours.

Visit any AT office or Loja de Cidadão

Locations: most major cities have one. Search “Loja de Cidadão” or “Repartição de Finanças” on Google Maps.

Lisbon options: Saldanha, Marvila, Areeiro. Porto: Boavista, Aliados. Smaller towns have one Repartição each.

Wait times: 30 min - 2 hours depending on location and time of month. Avoid the last 5 days of the month (peak tax volume).

Fill the registration form on-site

Staff hands you Modelo 1 RNPC. Fields:

  • Personal info (name, DOB, nationality)
  • PT address
  • Profession (estudante / trabalhador / desempregado is fine for a basic NIF)
  • Marital status

Hand back with your documents. You’ll receive your NIF and a printed “comprovativo” with the number on it. Save this - you’ll need it to set up everything else.

Path B - Non-EU citizen, before moving

For Americans, Brits, Canadians, etc., the rule used to be that you needed a fiscal representative even just to GET a NIF. As of 2022, this changed: non-EU citizens can now get a NIF without a representative if they’re already PT-resident at the time of request. But if you want to register before arriving, a representative is still required.

Option B1 - Wait until you arrive

Easiest path. Get your visa, fly in, get a residency address (rental, friend’s place, Airbnb), then visit an AT office same as Path A. Same €10.20 fee, no representative needed.

Option B2 - Use a fiscal-representative service

Companies like e-Residence, NIF Online, or Bordr charge €60-€150 to act as your fiscal representative. Process:

  1. Sign their terms; they appoint themselves as your representative on the AT system
  2. They submit Modelo 1 on your behalf with your documents
  3. You receive your NIF by email within 1-7 days
  4. Once you become PT-resident, you can switch the fiscal representative off (at the AT office)

Useful when: you need a NIF before flying in (e.g. to sign a rental contract remotely).

Option B3 - Have a PT-resident friend act as representative

Free, but the friend takes on actual responsibility - they receive AT mail on your behalf and are notionally responsible for compliance. Most people don’t want this responsibility for someone whose finances they don’t control.

Getting Portal das Finanças access (senha)

Once you have a NIF, the next step is the senha (password) for online access.

Request the senha at any AT office (or online)

Three paths:

  • In-person at AT office: ask staff. They print you a one-time code (código de adesão).
  • Online via portaldasfinancas.gov.pt → “Pedir senha”: requires you to enter NIF + some personal info. AT mails you the senha.
  • Via Cartão de Cidadão chip reader: if you have a PT cidadão card and a USB chip reader, you can authenticate without a senha at all.

All three are free (no fee for the senha itself).

Wait for the physical mail

AT sends the senha (a temporary password) by physical mail to your registered fiscal address. Timeline:

  • Major cities: 5-7 working days
  • Rural / smaller towns: 7-14 working days
  • International (if you’re non-resident): 2-6 weeks, sometimes never

No email, SMS, or in-person pickup option. Mail-only. Plan accordingly.

If your address changes before the mail arrives, the senha is lost and you have to re-request.

First login and password change

When the envelope arrives, it contains a temporary senha. Go to portaldasfinancas.gov.pt → Aceda ao Portal, enter NIF + temp senha. AT immediately prompts you to change to a permanent password.

Choose something you’ll remember - there’s no email-recovery flow. If you forget, you go through the whole mail-back process again.

Verify access works

After changing the senha, navigate to:

  • Os seus serviços → Identificação - verifies your registered address and personal info
  • Comprovativo de IRS - should show no past declarations if you’re new
  • Pagamentos - should show no pending payments

All clean? You’re set up. Now you can:

  • Open freelance activity (guide)
  • File IRS (guide)
  • Use e-Fatura (guide)
  • Pay tax bills, request certidões, etc.

Common stumbling blocks

Wrong address on registration. If you put a temporary address (Airbnb, hotel) when registering for the NIF, AT mails everything there forever until you update. Update via Portal das Finanças → Identificação → Comunicar morada once you have a stable address.

Senha mail returned undelivered. Common with rural addresses or new buildings. The senha is voided after one delivery attempt. Re-request once you confirm a deliverable address.

Multi-character senhas auto-generated. AT-generated senhas are typically alphanumeric mixed-case. Some people mistype (l vs I, 0 vs O). The envelope is hand-printed with reasonable typography but read carefully.

Trying to access from outside Portugal. Portal das Finanças works internationally - no IP restriction. But certain workflows (Auto-IRS, electronic payment) prefer SEPA banking which means a PT IBAN. Set up your PT bank account early.

Forgetting to register email + phone in the AT profile. AT uses these for secondary verification on some actions. Update via Identificação → Outros contactos.

After you have the senha

You can also enable Cartão de Cidadão authentication (if you’re a PT national) or Chave Móvel Digital (CMD - Portugal’s digital signature, free for residents). Both let you log in without typing the senha.

To set up CMD:

  1. Visit a Loja de Cidadão
  2. Bring your cidadão card or proof of identity
  3. They provision your CMD on the spot
  4. Use it for both AT and SS Direta from then on

CMD is faster and more secure than NIF + senha. Worth setting up if you’ll be a PT resident long-term.
