Portugal Inheritance Rules for Foreign Residents | 2026 Guide

Of all the admin that gets postponed after a move abroad, your will is probably the last thing on your mind. Residency first, then the NIF, then a bank account, then the first tax return. Succession planning tends to surface years later, either during a property purchase or after a death in the family.

That is unfortunate, because the Portugal inheritance rules for foreign residents are not harsh. On tax, Portugal is one of the gentlest countries in Europe. The difficulty is structural: the system is built differently from the one most people arriving from the UK, Ireland, the US or Canada grew up with, and the differences appear in places nobody thinks to check.

Here is how it actually works, and what to do about it.

Two separate questions, two separate answers

Portuguese law splits into two parts what many countries treat as a single problem:

1. Who inherits your assets (succession law)
2. What tax is due on the transfer (stamp duty)

These are decided under different rules and can point to different countries. You can be governed by English succession law and still owe Portuguese stamp duty. You can be entirely exempt from Portuguese tax and still find that Portuguese law, not your will, decides who gets the house. Keeping the two apart is the single most useful habit when reading anything on this subject.

Portugal has no inheritance tax. It does have stamp duty.

Portugal abolished inheritance and gift tax in 2004. What replaced it is Stamp Duty (Imposto do Selo), charged at a flat 10% on the free transfer of Portuguese assets, whether on death or by lifetime gift.

The exemption is where most families land. The following pay nothing at all, regardless of the value involved:

• Spouses and união de facto partners of at least two years

• Children and grandchildren

• Parents and grandparents

Everyone else pays 10%: siblings, nieces and nephews, cousins, friends, godchildren, and unmarried partners whose relationship does not meet the legal test.

One detail is worth getting right, because a lot of published guidance gets it wrong. You will often see the rate on Portuguese property quoted as 10.8%, made up of the 10% plus a further 0.8%. That extra 0.8% comes from a separate line in the Stamp Duty table which covers acquisitions for consideration or by gift. Inheritance is neither. On death, an exempt heir pays nothing at all on Portuguese property, and a non-exempt heir pays the 10%. The 0.8% becomes relevant when you hand property over during your lifetime.

Two points people miss. First, only Portuguese-situated assets are in scope: property here, Portuguese bank accounts, Portuguese-registered vehicles and boats, shares in Portuguese companies. A UK ISA, a Dublin-domiciled fund and a flat in Toulouse are all outside it, for tax. Whether Portuguese law gets to say who inherits them is a separate question, covered further down. Second, the tax is charged on the beneficiary, not the estate, which is the reverse of the UK approach.

A quick illustration. A Lisbon apartment with a rateable value (VPT) of €400,000 left to a daughter costs nothing. The same apartment left to a brother costs €40,000. Gift that apartment to the daughter during your lifetime instead and she pays €3,200, because the 0.8% applies to gifts even within the exempt family circle.

Forced heirship: the part that catches people out

Portugal reserves a fixed slice of your estate for close family, and no will can override it. This reserved slice is the legítima or quota indisponível. What is left over is the quota disponível, which you can leave to anyone you like.

A married person with two children can therefore direct only a third of their estate by will. The surviving spouse has been a protected heir in their own right since the 1977 reform of the Civil Code and cannot be written out.

Notice who is absent from that table. Unmarried partners are not protected heirs, no matter how long the relationship has lasted. Stepchildren are not protected heirs unless legally adopted. Under Portuguese default rules those two groups can receive nothing, which is usually the opposite of what was intended. Blended families need a will here more than anyone.

One planning tool worth knowing: since September 2018, couples marrying under the separation of property regime can renounce their status as each other's forced heirs in a prenuptial agreement. It has to be done before the marriage, and the surviving spouse keeps certain rights regardless, including the right to stay in the family home for at least five years. For second marriages with children from a first, it is often the cleanest solution available.

Can you apply your own country's law instead?

Often, yes. EU Regulation 650/2012, usually called Brussels IV, has governed cross-border estates since August 2015. Its default rule is that the law of your habitual residence at death applies to your entire estate, wherever the assets sit. Retire to the Algarve and stay there, and Portuguese succession law governs the villa here, that UK ISA, the Dublin fund and the flat in Toulouse alike.

Hold that against the tax position above, because the contrast is the whole point. Portuguese law decides who inherits the ISA, the fund and the French flat. Portugal takes no tax on any of them, because none is a Portuguese asset. Scope of the succession rules and scope of the stamp duty are two different maps, and reading one as though it were the other is where most of the confusion on this subject starts.

The Regulation also lets you elect the law of your nationality to govern the whole succession. The election has to be made expressly, and the sensible place for it is a Portuguese will covering your Portuguese assets, sitting alongside a home-country will for everything else.

Some practical caveats:

• The election has to be explicit. A will that simply divides your estate does not amount to a choice of law. The wording matters.
• British and American nationals can still use it. The UK opted out of the Regulation, but Portugal applies it universally, so a Portuguese notary will give effect to an election of English, Scottish or New York law.
• "UK law" does not exist for this purpose. England and Wales, Scotland and Northern Ireland are separate systems, and Scots law has its own protection for children and spouses. Specify which one.
• If you own here but live elsewhere, the default rules can loop back. A UK-resident owner of an Algarve property who makes no election will have English law applied by default, and English conflict rules refer land back to the country where it sits. The Portuguese house ends up under Portuguese rules anyway. An express election prevents that.
• Choice of law does nothing for tax. Portuguese stamp duty attaches to Portuguese assets no matter which country's succession law applies.

Your home country will probably still want its share

This is the part that gets left out of most online summaries. Portugal charging your children nothing does not stop your own country charging 40%, and for most people who move here that exposure is the larger of the two.

If you are British

The UK changed its test on 6 April 2025. Domicile and deemed domicile are gone for inheritance tax. What matters now is whether you are a long-term resident: UK tax resident for at least 10 of the previous 20 tax years. If you are, your worldwide estate falls within UK IHT, including everything you own in Portugal. If you are not, only your UK assets are caught, and UK assets are always caught regardless of where you live.

Leaving does not switch this off immediately. A tail period runs after departure, from three years for those resident 10 to 13 years, rising by a year for each additional year of residence, up to a maximum of 10. Someone who lived in the UK for 17 of the last 20 years and then moved to Cascais stays within the UK net for seven more tax years.

There is no inheritance tax treaty between the UK and Portugal. The new double taxation convention signed in September 2025 replaced the 1968 treaty and applies in Portugal from January 2026, with the UK provisions phasing in across 2026. It deals with income and capital gains, not inheritance. HMRC does allow unilateral relief for Portuguese stamp duty paid on the same asset, and since 10% is well below 40%, the credit normally absorbs the Portuguese charge in full.

If you are American

The US is the outlier: it taxes on citizenship, not residence. Moving to Portugal changes nothing, and neither does giving up US residence. Green card holders are in the same position for as long as they hold the card, sometimes longer.

The threshold is generous. From 1 January 2026 the federal estate and gift tax exemption is $15 million per person, or $30 million for a married couple using portability, made permanent by legislation passed in July 2025 and indexed for inflation from 2027. Above that the rate is 40%. Most families never come close.

Three things catch Americans in Portugal regardless:

• A non-citizen spouse. The unlimited marital deduction applies only where the surviving spouse is a US citizen. Leave everything to a Portuguese, British or other non-citizen spouse and the transfer is taxable above the exemption unless the assets pass through a Qualified Domestic Trust. Mixed-nationality couples are often unaware the rule exists.
• No estate tax treaty with Portugal. The US has estate tax treaties with the UK, Ireland, France, Germany and around a dozen other countries. Portugal is not among them, and the 1994 US-Portugal treaty covers income tax only. Relief for Portuguese stamp duty comes solely through the unilateral foreign death tax credit, and only on Portuguese-situated property.
• The state you left. Clearing the federal threshold is not the end of it. A number of states levy estate or inheritance tax at far lower thresholds, and moving abroad does not automatically end state domicile if you kept a property, a driving licence or a voter registration behind.

Heirs have an obligation of their own. A US person receiving more than $100,000 from a non-US estate has to report it on Form 3520 even though no tax is due on the receipt.

What your heirs will actually have to do

The Portuguese process is administrative rather than judicial. There is no probate court in the English sense.

1. Habilitação de herdeiros. A notarial deed identifying the heirs, done at a notary or at the Balcão das Heranças. Fees typically run to a few hundred euros, more where property registration is bundled in.
2. Modelo 1 declaration to Finanças. Due by the end of the third month following the month of death, so a death in March means a 30 June deadline. It lists all Portuguese assets, and it has to be filed even when every heir is exempt. An extension is possible where information on a particular asset is missing, but late filing otherwise brings penalties and blocks registration of the assets into the heirs' names.
3. Partilha, registration and release. The division deed, updating the Land Registry, and unfreezing bank accounts.

Foreign documents need an apostille and a certified translation. Every heir needs a Portuguese NIF, including those who have never set foot in the country. Almost all of it can be handled remotely through a power of attorney signed at a consulate. Realistically, budget several months from death to completed transfer.

The mistakes we see most often

• Assuming the home-country will covers everything. It may be valid here, but it will be read through Portuguese eyes unless it says otherwise.
• Relying on a joint bank account. Portugal has no automatic right of survivorship. The deceased's share forms part of the estate and the account is typically frozen until the paperwork is complete.
• Leaving a long-term partner unprotected. A união de facto of two years or more gets the partner the same stamp duty exemption as a spouse, but it does not make them an heir. There is no formal register: the status is proved by a declaration from the local junta de freguesia, which is worth obtaining in advance rather than leaving the survivor to establish it later.
• Gifting property to children early. It triggers the 0.8% that inheriting would not, the gift can be brought back into account when the estate is eventually divided, and the capital gains position on a later sale is often worse than if the child had inherited.
• Treating "no inheritance tax in Portugal" as the whole answer. It describes one of the two tax systems your estate will meet, and usually the less expensive one.

Inheritance is one of the few areas where the cost of getting it wrong falls entirely on other people. The Portuguese half of the picture is unusually kind to families. The half governed by your home country rarely is, and the two have to be read together to see where an estate actually stands.
