Tax Residence Certificate (Certidão de Domicílio Fiscal)

A certificate from the AT confirming the tax address associated with your NIF on the date of issue.

What it is for

  • Prove your address to a bank, telecoms operator or organisation that accepts this proof.
  • Include it in a rental application or credit assessment.
  • Confirm that a change of address has already been registered with the Tax and Customs Authority (Finanças).
Example (fictitious). Titus Gorila moved to Porto and updated his address on the Tax Portal (Portal das Finanças). Before notifying his insurer, he obtains the certificate to check whether the new address is already on record.

What it is

The tax residence certificate shows the address that the AT has registered for your NIF on the day it is issued. It serves as official proof of your tax address, but it does not prove that you actually live there. It should not be confused with the certificate of tax residence used in international contexts.

How we collect it

We request it using the holder's NIF and Tax Portal (Portal das Finanças) password. We deliver the official PDF issued by the AT.

Access required: Tax Portal (Portal das Finanças). Credentials are encrypted only during the collection and deleted at the end.

Things to note

If the registered address is incorrect or out of date, correct it first through the appropriate channel and only then request the certificate. An English version is also available, which may be useful abroad.

Frequently asked questions

Is there an English version?

Yes, the AT also provides the tax residence certificate in English.

Is it always valid as proof of residence?

It depends on who is asking for it. It confirms your tax address; some organisations require another document to prove where you actually live.
