How to Update Your Fiscal Address in Portugal as a Foreign Citizen

2025 Guide

If you’re a foreign citizen living in Portugal, updating your fiscal address (morada fiscal) with the Autoridade Tributária e Aduaneira (AT) is a key step to ensure you’re in compliance with Portuguese tax law and receive all relevant tax communications.

This guide explains how to update your fiscal address on the Portal das Finanças after your initial registration with a foreign address—and what to do once your new Portuguese address is entered.

Why Is It Important to Update Your Fiscal Address?

If you’ve moved from your home country to Portugal or changed your address within Portugal, it’s crucial to update your NIF (Número de Identificação Fiscal) record. Keeping your fiscal address up to date helps you:

  • Receive tax notifications and correspondence from AT
  • Access public services, healthcare, and legal residency rights
  • Eliminate the need for a tax representative, saving money
  • Avoid fines or administrative issues

Where and How to Update Your Fiscal Address

You can update your address online via the Portal das Finanças, but it’s a two-step verification process.

Step 1: Log In to the Portal das Finanças

Log in using your NIF and senha (password). If you don’t have an online account yet, you can register here (in Portuguese).

Step 2: Submit Your New Portuguese Address

  1. Go to:
    Cidadãos > Serviços > Dados Pessoais Relevantes > Alterar Morada
    Or try this direct link (login required):
    https://www.portaldasfinancas.gov.pt
  2. Enter your new Portuguese address in full:
    • Street name and number
    • Floor or apartment number (if applicable)
    • Postal code and locality
  3. Submit the change request.

Step 3: Wait for the Confirmation Code by Mail

This is the most critical step.

After submitting your address, the Tax Authority will mail a verification code (código de validação) to your new address via registered post.

  • This code typically arrives within 5–10 business days
  • You must enter it in the Portal das Finanças to validate the address

Step 4: Enter the Code to Confirm the Address

Once you receive the letter:

  1. Return to the Portal das Finanças
  2. Navigate to the “Confirmar Morada” section (found under personal data)
  3. Enter the code exactly as printed

Only after this step will your fiscal address be officially updated.

What Happens After Confirmation?

  • Your address will be officially linked to your NIF
  • If you previously had a fiscal representative (because your address was outside Portugal), you may now remove the representative. This must be done at a Finanças office or via e-Balcão.

Important Tips

  • If the code doesn’t arrive, you can resend the request through the portal
  • Double-check that your name is on your mailbox—mail with the code may be returned otherwise
  • This process can only be completed by you or a legal representative
