Tax Debt / No Debt Certificate (Certidão de Dívida e Não Dívida)

A certificate from the Tax and Customs Authority (Finanças) stating whether your tax situation is in order or whether there are debts, listing them where applicable.

What it is for

  • Apply for grants, public contracts or tenders that require a regularised tax situation.
  • Provide it to a bank or business partner that requests it.
  • Check your standing with the AT before taking on a commitment.
Example (fictitious). Padaria Gorila is about to sign a contract with a municipal supplier. Beforehand, it obtains the certificate and checks the expiry date written on the document.

What it is

This is the document in which the AT declares a taxpayer's tax situation. If there are outstanding debts, the certificate identifies them. Being regularised does not always mean owing nothing: an authorised payment plan or a proceeding suspended by a guarantee may be compatible with a regularised status.

How we collect it

We need the holder's NIF and Tax Portal (Portal das Finanças) password. We obtain the certificate and deliver it as an official PDF.

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

Things to note

The certificate only covers the Tax and Customs Authority: debts to Social Security or to banks are not included. Requesting it does not settle any existing debt.

Frequently asked questions

Does «regularised» mean I owe nothing?

Not always. Read the wording of the certificate, as certain debts with authorised payment plans or guarantees may coexist with a regularised situation.

Can I reuse an old certificate?

Check the validity period written on the document and what the organisation requires. If it has expired, request a new one.
