Search “does Portugal have inheritance tax” and the first honest answer you will find is no, and the second honest answer is that the question was never really about Portugal. Most of the families who search inheritance tax Portugal questions are trying to work out something else: whether moving to the Algarve actually gets them out of the 40 percent bracket back home, or whether it just moves the paperwork to a country where nobody in the family reads the forms. Both outcomes are possible. Which one applies to a specific estate depends on two rulebooks that were rewritten within the last two years and that answer completely different questions.
Portugal’s rule is about where an asset sits. The UK’s rule, changed in April 2025, is about how long a person actually lived in the UK, not about where they were born or where their parents are buried. Confusing the two is the single most common and most expensive mistake in this whole topic: treating “I live in Portugal now” as if it settles the UK question. Portuguese inheritance tax and UK inheritance tax are two separate calculations, not one shared outcome.
This is a companion to our broader guide to moving to Portugal from the UK, which covers the visa and relocation side. Here we go deeper on the one question that guide deliberately leaves for a specialist: what happens to an estate.
Portugal Doesn’t Have an Inheritance Tax. It Has Stamp Duty
Portugal scrapped a standalone inheritance and gift tax back in 2004. What replaced it was not a gap, it was a rebrand with a real mechanism behind it: Imposto do Selo, Stamp Duty, extended to cover gratuitous transfers of property, meaning anything passed on by inheritance or by gift rather than sold. The relevant charge sits in verba 1.2 of the Stamp Duty Code’s general table, and the rate is a flat 10 percent of the asset’s tax value, with no regional variation and no sliding scale by estate size the way the UK’s system has.
The 10 percent is not universal, though. Portuguese law draws a hard line around direct family. A spouse or de facto partner (unido de facto), descendants (children, grandchildren, and further down the line), and ascendants (parents, grandparents) are fully exempt from the 10 percent. For that group, an inheritance of Portuguese assets genuinely does arrive free of this tax. Everyone else pays the full 10 percent on what they receive: a sibling, a niece or nephew, a friend, a godchild.
Real estate does not add a second layer on death. The 0.8 percent property charge in verba 1.1 applies to purchases and gifts of real estate, not to inheritance, so a non-exempt heir pays the same 10 percent on a flat as on cash. So the honest version of “Portugal has no inheritance tax” is: correct for a spouse, a child, or a parent, and wrong for almost anyone else who inherits Portuguese property.
What Actually Counts as a Portugal-Situated Asset
Stamp duty is a territorial tax. It reaches assets located or registered in Portugal: Portuguese real estate, Portuguese bank accounts, shares in a Portuguese company, and similar Portugal-registered rights. It does not reach a UK house, a UK pension, or a UK bank account, regardless of where the deceased was living or how long they had lived there. Consider a British retiree who dies as a Portuguese tax resident. They own a flat in Cascais and a savings account in Manchester. Only the Cascais flat enters Portugal’s Stamp Duty calculation. The Manchester account is outside it entirely, on the Portuguese side.
That does not mean the Manchester account, or the Cascais flat for that matter, escapes UK inheritance tax.
The UK Side Changed in April 2025: Domicile Is Gone
For decades, UK inheritance tax turned on domicile, a concept borrowed from common law that asked where someone’s permanent home really was, in a legal and often ancestral sense, regardless of where they currently lived. Domicile was a real, litigated legal status, and it was also the mechanism that let long-term UK residents shelter worldwide wealth from IHT for years at a time.
Finance Act 2025 closed that specific gap. From 6 April 2025, domicile stopped being the test for UK inheritance tax altogether, replaced by a new long-term UK residence test written into section 6A of the Inheritance Tax Act 1984, set out in HMRC’s own Inheritance Tax Manual. The question the new test asks is much narrower and much easier to check against an actual calendar: how many of the last 20 tax years was this person UK tax resident? Someone resident for at least 10 of those 20 years is a “long-term UK resident,” and a long-term UK resident’s worldwide estate falls inside UK inheritance tax at death, wherever they are living and wherever the assets sit.
Someone who never crosses that 10-year threshold is taxed only on their UK-situated assets: a UK property, a UK bank account, UK-registered investments. Everything else, wherever it is, sits outside the UK charge. A UK non-resident who was also never a long-term resident under the new test has a narrower UK inheritance tax exposure than most headlines suggest. Domicile still matters for deaths that occurred before 6 April 2025 and for a handful of legacy trust situations under transitional rules, but for anyone assessing where they stand today, the residence count is the number that decides it, not a domicile argument.
The Tail: Why Leaving the UK Doesn’t End It Immediately
Becoming a long-term resident is not undone the moment someone books a one-way flight to Faro. The rules build in a tail period, and it scales with how long the person was actually resident before they left, not a flat number applied to everyone. Per HMRC’s own guidance on the tail rule, someone who was UK resident for 10 to 13 of the relevant 20 tax years carries a 3 tax year tail after leaving. That tail lengthens by one year for each additional year of prior residence, up to a maximum 10 year tail for someone who was resident for 20 years or more. During that tail, the same worldwide-estate exposure that applied while they were still living in the UK continues to apply, even though they have genuinely relocated to Portugal, bought property there, and built a life around it.
The tail does eventually clear: once it ends, the worldwide test stops applying. For a family doing the arithmetic, that means the honest question is never “have I moved,” it is “how many of the last 20 tax years, counted precisely, was I actually UK resident, and how many years of non-residence have I banked since.” Assuming that a round number, five years abroad, is automatically safe is exactly the kind of error that catches people here.
The Nil-Rate Band, and What It Still Protects
Where UK inheritance tax does apply, whether to a worldwide estate under the long-term residence test or to UK-situated assets only, the same allowances apply first. Per current UK government guidance, every estate gets a 325,000 pound nil-rate band before the 40 percent rate starts. A further residence nil-rate band of up to 175,000 pounds is available where a main home passes to children or grandchildren, tapered away above 2 million pounds at a rate of 1 pound lost for every 2 pounds the estate exceeds that threshold. Both bands are transferable between spouses and civil partners, so a couple can combine unused allowances for up to 1 million pounds of combined relief before the 40 percent rate applies to anything. Both the nil-rate band and the residence nil-rate band are frozen at their current levels until 5 April 2031.
Where the Two Systems Can Reach the Same Euro
Put the two rules next to each other and one real overlap scenario appears. Take a UK long-term resident who has banked at least 10 of the last 20 tax years as UK resident and has not yet cleared their tail period. They own Portuguese real estate. They leave that property to someone outside the Portuguese direct-family exemption, a sibling, a friend. Portugal charges that heir 10 percent Stamp Duty on the property’s value. Separately, because the deceased was a UK long-term resident, the same property sits inside their worldwide estate for UK inheritance tax, taxed at 40 percent above the nil-rate band, alongside everything else they owned.
There is no treaty standing between those two charges. The UK and Portugal do not have an inheritance tax treaty. A new UK-Portugal double taxation convention entered into force on 29 December 2025, but it addresses only income tax, capital gains tax and corporation tax and says nothing about inheritance, consistent with HMRC’s own Double Taxation Relief Manual summary for Portugal, which likewise lists no inheritance or estate tax provision. HMRC does offer unilateral relief: a domestic UK provision that can credit foreign tax paid on the same asset against the UK inheritance tax otherwise due on it. Under section 159 of the Inheritance Tax Act 1984, HMRC must allow that credit once its conditions are met, but the credit cannot exceed the UK tax on that property.
None of this is tax, financial or legal advice, and Swift Cargo is not a licensed tax advisor, financial planner or solicitor. Anyone whose situation resembles the scenario above, a UK long-term resident with Portuguese property and a non-exempt intended heir, should get a written opinion from a cross-border estate planning specialist who works across both the UK and Portuguese systems before assuming either country’s exemptions apply.
This Is Not the Same Question as Who Inherits
Tax and succession are two different rulebooks. Portuguese succession law, separate from Stamp Duty entirely, applies forced heirship by default: a fixed share of an estate, the legítima, is reserved for a spouse, children and parents, regardless of what a will says, if Portuguese law governs the succession. That default applies based on habitual residence at death, not nationality.
A British national is not simply stuck with that default. Under the EU Succession Regulation, Regulation 650/2012, commonly known as Brussels IV, an individual can explicitly elect the law of their own nationality to govern their estate instead, through a clause in a validly drafted will. Portugal, as a state bound by the regulation, will honour that election for a British national’s estate even though the UK itself never adopted Brussels IV. Elect English and Welsh law, for instance, and its far broader testamentary freedom can apply to a UK national’s Portuguese assets instead of Portuguese forced heirship. That only works if the will is drafted correctly to make the election explicit.
Electing UK law to avoid forced heirship changes who receives what. It does not change Portugal’s Stamp Duty exemption categories or the UK’s long-term residence test. A family can get the succession election right and still be caught by the Stamp Duty and inheritance tax overlap described above, or get the tax planning right and still leave an estate subject to forced heirship because no election was made. Both questions need addressing, separately, and both need a specialist: a solicitor qualified in cross-border succession law for the will, a cross-border estate planning specialist or accountant for the tax exposure.
Getting the paperwork moving is still a practical, solvable step.
Whatever your estate planning turns out to require, a Portuguese NIF and a clear record of what you actually own in each country make every later conversation with a specialist faster. If shipping household goods to Portugal is part of your own move, see real costs and timelines first.
What Actually Determines Your Exposure
Count your own UK residence years first, precisely, against the actual 20-year window that applies at the relevant date, not a rounded impression of “a while ago.” That count, not where you currently live, decides whether your worldwide estate is inside UK inheritance tax at all. Next, identify which Portuguese assets you or a relative actually hold, since only Portugal-situated property and accounts enter the Stamp Duty calculation, and confirm who the intended heirs are and whether they fall inside Portugal’s direct-family exemption. If a UK long-term resident owns Portuguese property destined for someone outside that exemption, that is the specific overlap scenario worth a specialist’s attention before anything else. Separately, check whether a will has actually made a Brussels IV election, since silence defaults to Portuguese forced heirship for Portugal-based succession, a different outcome from what most UK wills assume.
A Portuguese estate is handled by a cabeça de casal, typically the surviving spouse. They need a Portuguese tax number, the NIF, to act on the estate’s behalf; our guide to opening a bank account in Portugal covers how that number is obtained and what it unlocks. Anyone building a long-term residence timeline in Portugal, rather than administering an existing estate, should also read our guide to Portuguese citizenship, passports and residence permits, since residence status there interacts with the same long-term timelines this article discusses on the UK side. Inheritance tax is also a separate question from Portugal’s own income tax residency regime: our NHR Portugal tax guide covering the IFICI successor regime explains what that scheme does and does not cover, and it is not a route around Stamp Duty. And if pension and income tax rather than inheritance is the more immediate question, our companion guide to Portugal’s retirement visa and pension tax rules covers that separate but related ground.
Getting This Right Costs Less Than Getting It Wrong
Inheritance tax Portugal planning and UK estate planning are not the same exercise, and the families who get burned by this topic are rarely the ones who did no planning at all. They are usually the ones who did some planning, correctly, for one half of the problem, and then assumed the other half was already covered because the first half felt thorough.
A single paid conversation with a cross-border estate planning specialist, someone who genuinely works across both the UK and Portuguese systems, is a small cost measured against either a 40 percent UK charge or a 10 percent Portuguese one landing on a family that assumed neither applied. This guide can tell you which two rulebooks are in play and where they can overlap. It cannot tell you what your own residence count is, what your own will actually says, or what your own estate is worth. Get those three answered by someone qualified before you rely on anything else you have read on this topic, including this article.

Frequently Asked Questions
Does Portugal have an inheritance tax?
Not in the form most people mean. Portugal abolished a standalone inheritance tax in 2004. What applies instead is Stamp Duty, Imposto do Selo, charged at 10 percent on Portugal-situated assets passed on death or by gift. Spouses, civil partners, children, grandchildren, parents and grandparents are fully exempt from that 10 percent. Anyone else pays it: a sibling, a niece or nephew, a partner who does not qualify as a unido de facto, or a friend.
How much UK inheritance tax will I pay if I live in Portugal?
It depends on your UK residence history, not where you live now. Since 6 April 2025, UK inheritance tax no longer runs on domicile. It runs on a long-term residence test: anyone UK tax resident for at least 10 of the last 20 tax years is a long-term resident and their worldwide estate is taxable at 40 percent above the 325,000 pound nil-rate band, wherever they are living at death. Someone who never met that test is only taxed on UK-situated assets. This is not tax advice; the exact figure depends on your specific residence years and estate, and needs a professional calculation.
What happened to the domicile rule for UK inheritance tax?
It was replaced. Finance Act 2025 removed domicile as the test for UK inheritance tax from 6 April 2025 and introduced a new long-term UK residence test in its place, based on how many of the last 20 tax years someone was UK tax resident. Domicile still matters for deaths before that date and in a small number of legacy trust situations, but for anyone assessing their position today, residence history is the operative test, not domicile.
Can I be taxed by both the UK and Portugal on the same inheritance?
Yes, this is a real gap, not a hypothetical one. There is no inheritance tax treaty between the UK and Portugal. The new UK-Portugal double taxation convention in force since 29 December 2025 covers income tax, capital gains tax and corporation tax, not inheritance. So a UK long-term resident who leaves Portuguese real estate to a non-exempt heir can trigger both Portuguese Stamp Duty and UK inheritance tax on the same asset, with only unilateral UK relief available, not a treaty. Get a cross-border estate planning specialist to check this before it becomes your family’s problem.
Does forced heirship in Portugal affect who inherits my estate?
It can, and this is a separate question from tax entirely. Portuguese succession law reserves a fixed share of an estate for a spouse, children and parents by default, regardless of what a will says. A UK national can usually avoid this by explicitly electing UK law to govern their estate under the EU Succession Regulation, commonly called Brussels IV, in a validly drafted will, even though the UK itself never adopted that regulation. This is a legal drafting question, not a tax one, and needs a solicitor qualified in both jurisdictions, not general guidance.
Do I still pay UK inheritance tax if I’ve lived in Portugal for years?
Possibly, for a while. Someone who qualified as a UK long-term resident before leaving does not lose that status the moment they move. A tail period applies, commonly three to ten tax years depending on how long they were UK resident, during which their worldwide estate can still fall inside UK inheritance tax. Confirm your own dates against a professional calculation rather than assuming a fixed number of years.
