How to Update Tax Address on Portal das Finanças

If you have moved to Portugal and become a Portuguese tax resident, or you have changed addresses within Portugal, you need to update your tax address (domicílio fiscal) on Portal das Finanças. This is a legal requirement — Portuguese law gives you 60 days from the change to update with Autoridade Tributária e Aduaneira. This guide covers the 60-day rule, the difference between a tax address and a residency address, the step-by-step update process, and what to do afterwards.

The 60-day rule

When you become a Portuguese tax resident — typically by spending more than 183 days in Portugal in a calendar year or having your habitual home in Portugal — you have 60 days to update your tax address on Portal das Finanças. The same 60-day window applies if you change addresses within Portugal.

Missing the 60-day deadline can result in fines from Autoridade Tributária. The amount depends on the specific case but generally falls between €75 and €375 for individuals. More importantly, tax notices continue to go to your old address, which can lead to missed deadlines for tax filings and additional penalties.

Tax address vs residency address — what’s the difference

For most Portuguese tax residents, the tax address and residency address are the same — your home address. They become different only in specific cases, such as when you use a fiscal representative’s address as your tax domicile.

Step-by-step: domicílio fiscal update

1. Prepare proof of your new address. You need a Portuguese proof of address — Atestado de residência from Junta de Freguesia, Título de residência from AIMA, CRUE (for EU citizens), a recent utility bill, or a rental contract. See proof of address Portugal for details, and CRUE for EU citizens.
2. Log in to Portal das Finanças. Go to portaldasfinancas.gov.pt and log in with your NIF and password. If you do not have your password yet, see how to receive your NIF password.
3. Navigate to address settings. In the search bar, type “Domicílio Fiscal” and click “Aceder”. Or navigate to Cidadãos > Serviços > Domicílio Fiscal > Comunicação/Alteração de Domicílio.
4. Submit the new address. Enter your new Portuguese address: street, number, postal code, city. Confirm the change. Portal das Finanças may ask you to upload proof, depending on your case. For most updates, the change takes effect immediately.
5. Confirm the change took effect. Return to “Domicílio Fiscal” and verify the new address is shown. If the change is not visible within 5 business days, contact AT through e-balcão at info.portaldasfinancas.gov.pt or call CAT at +351 217 206 707. AT’s official guidance on the domicílio fiscal is in the Morada (Domicílio Fiscal) section.

After moving to Portugal tax address — what comes next

• Cancel fiscal representation (optional). If you appointed a fiscal representative when you first applied for NIF Portugal as a non-resident, you can now cancel that fiscal representation. Updating your tax address is the first step — see how to cancel fiscal representation.
• Activate electronic notifications (optional). Once your tax address is updated and you no longer need a representative, activate electronic notifications (NCEPF) through Portal das Finanças. AT then delivers future correspondence to your account instead of by post.
• Update other Portuguese records. Also update your address with social security (Segurança Social, NISS), your bank, and your healthcare provider (SNS).

AIMA address Portugal — what to do for non-EU residents

Non-EU residents with a Título de residência must also keep their address up to date with AIMA (Agência para a Integração, Migrações e Asilo, the migration agency that replaced SEF in 2023). AIMA address updates are done separately from tax address updates — through the AIMA portal or in person at an AIMA office.
