Tax Authority (Finanças)PDF form

Application for a NIF for an Undivided Estate (Pedido de NIF para herança indivisa)

A Tax and Customs Authority (Finanças) form for requesting a tax number for an estate that has not yet been divided. You receive it blank, with guidance.

What it is for

  • Obtain a separate NIF for an estate that has not yet been divided
  • Identify the deceased, the estate administrator and the heirs
Example (fictitious). Titus Gorila is the administrator of his grandmother's estate and needs a NIF for the estate before it is divided.

What it is

This is the Tax and Customs Authority form in which the deceased, the estate administrator (cabeça de casal) and the heirs are identified, so that a NIF can be assigned to the undivided estate. It is submitted by the estate administrator or by a duly authorised representative. The form does not replace the formal recognition of heirs (habilitação de herdeiros), and the NIF is not assigned automatically: it depends on the review by the Tax and Customs Authority (Finanças).

What you receive

You receive the official blank PDF form, with an explanation of what it is for. The Titus assistant answers your questions about filling it in. You can combine it with other documents in the same request, with a single payment. We do not ask for any password for forms.

Things to note

The PDF is blank; the estate administrator or the authorised representative fills it in and signs it. Please ask the Tax and Customs Authority (Finanças) to confirm the version and the documents to attach. We do not submit the application or guarantee that the NIF will be assigned.

Frequently asked questions

Who can submit the application?

The estate administrator or a representative with the authority to do so.

Does the form prove who the heirs are?

No. It does not replace the formal recognition of heirs; it only identifies the people for the purpose of assigning the NIF.
