NIF for Inheritance in Portugal (2026): What Heirs Need to Do
When a relative dies in Portugal (or leaves assets in Portugal), the succession process almost always hits the same administrative wall: you can’t move forward without the right NIFs.
In practice, you may need:
the deceased person’s NIF (usually already exists),
a Portuguese NIF for the head of the estate (“cabeça-de-casal”),
a Portuguese NIF for each heir/beneficiary, and sometimes
a separate NIF for the “inheritance estate” (Herança Indivisa) before certain tax filings can be submitted.
This guide explains what heirs typically need to do in 2026, the deadlines that matter, and the fastest way to get the missing NIF(s) so the inheritance can progress.
Quick answer
If you’re handling an inheritance in Portugal, expect to need Portuguese NIFs. Without them, you’ll usually be blocked from tax filings, bank actions, and property transfer steps.
- Identify the head of the estate (“cabeça-de-casal”) — this person is responsible for key filings.
- Collect NIFs: the deceased person’s NIF + the head of estate’s NIF + each heir’s NIF.
- If an heir has no NIF, obtain one as a non-resident first (with a foreign address).
- Report the death and submit the Stamp Duty declaration (Modelo 1) within the official deadline.
- Complete the legal succession steps (heirs certificate, asset registration, property transfer).
Tip: If heirs are abroad, the biggest delays usually come from missing NIFs and paperwork formalities. Getting NIFs first keeps the process moving.

Why NIFs matter in a Portuguese inheritance
In Portugal, inheritance (“succession”) typically involves tax filings and legal registration steps. If any of the required NIFs are missing, the process often stalls—especially when heirs are abroad.
Most commonly, you’ll need:
the deceased person’s NIF (usually already exists),
the head of estate’s NIF (“cabeça-de-casal”),
the NIF of each heir/beneficiary who will be identified in the inheritance paperwork and tax filings,
and sometimes a separate NIF for the inheritance estate (Herança Indivisa) before certain submissions can be made.
Step-by-step: what heirs need to do (2026)
Step 1 — Confirm who is the head of the estate (“cabeça-de-casal”)
The head of estate “cabeça-de-casal (cabeca-de-casal)” is the person who handles inheritance matters until the estate is distributed. In practice, this is often the surviving spouse or the closest heir, but heirs can agree on another person.
Why it matters: this person is typically the one who must report the death and handle the initial tax declaration steps.
Step 2 — Gather the essentials (the “NIF pack”)
Before anything else, collect:
The deceased person’s full name + NIF (check old Portuguese documents, tax letters, bank paperwork, property documents)
The head of estate’s identity details + NIF
The identity details + NIF of each heir/beneficiary
If an heir does not have a Portuguese NIF yet, obtain it early. Waiting until the notary/bank asks for it is one of the most common causes of delays.

Step 3 — Report the death and submit the Stamp Duty declaration (Modelo 1)
In Portugal, the death must be communicated to the Tax Authority and the inheritance is declared through the Stamp Duty process (Modelo 1).
Key points to understand:
This filing is required when the deceased left assets to be transferred.
It must be done within the official deadline (commonly “by the end of the third month after the month of death”).
The filing is usually handled by the head of estate.
In many cases, heirs also need the NIF for the inheritance estate (Herança Indivisa) before the Modelo 1 submission can be completed.
Step 4 — Complete the legal succession steps (heirs certificate + asset registration)
For most inheritance processes, the next steps include:
identifying heirs (often via an heirs certificate / “habilitação de herdeiros”),
listing/declaring assets (property, vehicles, bank accounts, shares, etc.),
and registering the transfer of assets to the heirs.
If there is Portuguese real estate involved, this is where missing NIFs can cause major delays (property transfers and registrations are NIF-driven).
Step 5 — Pay any applicable taxes (if not exempt) and finalise registrations
Portugal’s inheritance “tax” is usually handled through Stamp Duty rules. Some close family situations are exempt from payment, but reporting obligations may still apply depending on the case and assets.
If taxes are due, the tax office will notify the head of estate about payment steps.
Step 6 — If you are abroad: get your NIF as a non-resident first
If you are an heir living outside Portugal, your NIF is normally issued first as a non-resident NIF with your foreign address.
That is normal—and it is often exactly what is needed to:
be listed as an heir/beneficiary,
sign succession documents,
deal with Portuguese banks,
and progress property transfer steps.
If you want to apply for a NIF number directly with the tax office you can read our article explaining in details how to book a Finanças appointment.
If later you move to Portugal or become tax resident, you can update the NIF address/status with the proper supporting documents.
Common mistakes that delay inheritances (and how to avoid them)
Waiting too long to obtain heirs’ NIFs
Inheritance files can’t progress smoothly if heirs cannot be properly identified in filings and registrations.
Confusing “Portuguese address” requirements
Non-resident heirs normally start with a foreign address. Trying to “force” a Portuguese address without proper supporting documents often creates back-and-forth.
Missing NIF of the deceased
In most cases it exists already—start by searching old Portuguese paperwork before assuming you need to “create” one.
Document mismatch (names, accents, different spellings)
Even small inconsistencies can trigger delays. Use the same spelling across passport, death certificate, and forms.

FAQ
Do all heirs need a Portuguese NIF?
In most inheritance cases, each heir/beneficiary who must be identified in Portuguese paperwork (tax filings, bank steps, property transfer/registration) will need a Portuguese NIF. Missing NIFs are one of the most common reasons inheritances get delayed.
What is the deadline to report a death to Finanças and submit the inheritance declaration?
Portugal’s official guidance commonly refers to reporting the death and filing the Stamp Duty participation within the set deadline (often by the end of the third month after the month of death). If you are close to the deadline, act quickly to avoid unnecessary delays.
Is inheritance tax payable in Portugal?
Portugal typically handles inheritance through Stamp Duty rules. Some close family situations may be exempt from payment, but reporting/filing obligations may still apply depending on the assets and case.
Can I get a NIF from abroad for an inheritance case?
Yes. Many non-resident heirs obtain a NIF remotely. In practice, remote routes often involve a representative submitting the request with scanned documentation. A specialised service can simplify this if you want a faster, guided process.
Do I need a fiscal representative as a non-resident heir?
Requirements can depend on your residency status and how you will use the NIF. In many cases, non-residents use a representative to handle filings and communications, especially when managing an inheritance from abroad.
What if the deceased person never had a Portuguese NIF?
This is less common, but it can happen (especially for non-Portuguese citizens who never interacted with Finanças). In those cases, the notary/lawyer handling the succession may advise the correct path with the tax office. Start by checking whether the deceased has any Portuguese documents where a NIF might appear.
