UK Inheritance Tax for UK Expats in Portugal, Does It Still Apply?

UK Inheritance Tax for UK expats in Portugal, does it still apply? In many cases, yes. Moving to Portugal does not automatically remove you from the scope of UK Inheritance Tax (IHT). Whether UK IHT applies depends mainly on your UK domicile status, deemed domicile status, and the location of your assets. Many UK expats in Portugal remain within UK IHT on worldwide assets, even after years abroad.

The quick answer

• If you are UK domiciled or deemed domiciled, UK IHT can apply to your worldwide assets, including assets in Portugal.
• If you are not UK domiciled and not deemed domiciled, UK IHT generally applies only to UK situated assets.
• Portugal does not have a classic inheritance tax, but it can charge Stamp Duty (Imposto do Selo) at 10 percent on certain Portuguese assets passing to non exempt beneficiaries.
• There is no comprehensive UK Portugal inheritance tax treaty that automatically prevents double taxation in every scenario, planning and documentation are important.

Why this matters for UK expats living in Portugal Many families assume that becoming Portuguese tax resident, registering as a resident, or using the Non Habitual Residence regime automatically changes their UK IHT position. It does not. IHT is driven more by domicile than by day to day income tax residence. As a result, inheritance planning often becomes one of the biggest tax exposures for UK expats, especially where property, pensions, investment portfolios, or a family business remain connected to the UK.

1) The main rule, UK domicile is the key driver UK IHT is primarily based on domicile, not where you live today. Broadly:

• UK domiciled individuals are within UK IHT on their worldwide estate at death, subject to allowances and reliefs.
• Non UK domiciled individuals are generally within UK IHT only on UK situated assets.

Domicile is a legal concept. You can be resident in Portugal and still be UK domiciled. Many UK citizens who relocate later in life keep a UK domicile of origin unless they clearly establish a domicile of choice elsewhere. Establishing a new domicile usually requires living permanently or indefinitely in the new country and demonstrating strong intention, such as long term settlement, family ties, home, and future plans focused outside the UK.

2) Deemed domicile can pull you back into UK IHT Even if you have taken steps to shed UK domicile, the UK has deemed domicile rules that can bring you back into worldwide IHT. The key situations include:

• 15 out of 20 rule: if you have been UK tax resident for at least 15 of the previous 20 tax years, you can become deemed domiciled for UK IHT.
• Formerly domiciled resident rule: if you were born in the UK with a UK domicile of origin and later return to UK residence, you can become deemed domiciled quickly.

For many UK expats in Portugal who left the UK years ago, the 15 out of 20 rule may be less relevant if they have been non UK resident for a sustained period. For those who move back and forth or maintain significant UK residence, it can become a major risk area and should be reviewed carefully.

3) What assets does the UK tax if you are non domiciled? If you are not UK domiciled and not deemed domiciled, UK IHT usually applies only to UK situated assets. Typical UK situated assets include:

• UK residential property and UK land.
• Shares listed on the UK stock exchange, depending on the structure and where the company is incorporated.
• UK bank accounts, although specific classifications can be complex.
• Interests in UK businesses or partnerships.

UK residential property deserves special attention. UK IHT can apply to UK residential property even when held indirectly through certain offshore structures, due to rules introduced to counter avoidance. If you still own a UK home, let alone one held in a company, your IHT exposure may be significant.

4) Nil rate band, residence nil rate band, and the headline tax rate UK IHT is commonly charged at 40 percent on the value of the estate above the available allowances, subject to exemptions and reliefs. Key allowances include:

• Nil Rate Band (NRB): a threshold before IHT is charged, subject to tapering in some cases and to earlier gifts.
• Residence Nil Rate Band (RNRB): additional allowance potentially available when a qualifying home is left to direct descendants, subject to conditions and tapering for larger estates.
• Spouse and civil partner exemption: transfers to a spouse or civil partner can be exempt, though there are special limitations where the recipient spouse is not UK domiciled.

In cross border families, the RNRB can be misunderstood. It is linked to a qualifying residence and direct descendants, and it can be reduced for higher value estates. It is also affected by downsizing and by whether the home is left to the right beneficiaries in the right way.

5) Does Portugal tax inheritance? Portugal does not impose a typical inheritance tax between close family members, but it can impose Stamp Duty (Imposto do Selo) on certain transfers, including gifts and inheritances of Portuguese situated assets. The standard rate is often 10 percent, with an additional 0.8 percent potentially applying for Portuguese real estate in some situations.

However, there is a major family exemption. Transfers to a spouse, civil partner, descendants, and ascendants are generally exempt from this Stamp Duty in Portugal. Transfers to other beneficiaries, such as siblings, nieces, nephews, or unrelated individuals, may trigger the 10 percent charge.

Practical impact: a UK expat in Portugal could face UK IHT on worldwide assets due to domicile, while Portuguese Stamp Duty may still be relevant depending on where assets are located and who inherits them.

6) Can you be taxed twice on the same inheritance? Potentially, yes. Because the UK and Portugal do not have a broad, modern inheritance tax treaty that covers all scenarios the way some other country pairs do, double taxation can arise, especially when each country asserts taxing rights on different bases. The UK can tax based on domicile, Portugal can tax based on asset location and beneficiary relationship through Stamp Duty.

That said, double taxation is not inevitable. Relief may be available through:

• Unilateral relief in the UK in some cases, where foreign death duties have been paid on the same asset.
• Careful structuring of ownership, beneficiary designations, and asset location.
• Good estate documentation, including clear records of where assets are situated and which taxes were paid.

The correct treatment depends on the specific asset, the beneficiary, and the timing, so coordinated UK and Portuguese advice is usually essential.

7) UK pensions, are they subject to IHT if you live in Portugal? UK pension planning is one of the most important and misunderstood areas for UK expats. Many UK defined contribution pensions can sit outside the estate for UK IHT, but this depends on the type of pension, scheme rules, nomination forms, and how benefits are taken.

Key points to review include:

• Beneficiary nominations: ensure expressions of wish are up to date and aligned with your broader estate plan.
• Crystallisation and withdrawals: drawing benefits can move value into your personal estate, increasing IHT exposure.
• Death benefits taxation: income tax may apply to pension beneficiaries depending on the member's age at death and the nature of the benefits.

For UK expats in Portugal, pensions also need to be reviewed under Portuguese tax rules, especially where distributions are taken. But the IHT point remains, the pension may be one of the most efficient assets to pass on if structured and administered correctly.

8) The seven year rule for gifts, and why it still matters abroad UK IHT includes a gifting regime that can reduce the taxable estate if gifts are made sufficiently early. The most well known rule is that many lifetime gifts to individuals become fully outside the estate if you survive seven years after making them, subject to detailed conditions.

Important practical details include:

• Potentially Exempt Transfers: gifts to individuals can fall outside IHT after seven years.
• Taper relief: may reduce IHT on certain gifts made between three and seven years before death, but it does not reduce the value of the gift, only the tax.
• Gift with reservation rules: if you give an asset away but keep benefiting from it, such as gifting a home but continuing to use it rent free, it can remain in your estate.
• Regular gifts out of income: can be exempt if properly documented and if they do not reduce your standard of living.

Living in Portugal does not remove these rules. UK IHT looks at your domicile status and your gifting history, regardless of where you were living when the gifts were made.

9) UK property, the biggest IHT exposure for many expats UK residential property is often the dominant asset and can create several complications:

• Liquidity: IHT may be due within a short period, sometimes forcing sales or refinancing.
• Valuation: HMRC expects a supportable market value at death and can challenge it.
• Joint ownership: how a property is owned, joint tenants vs tenants in common, affects what passes under a will and what passes by survivorship.
• Let property and compliance: income tax compliance and local management are separate issues, but they often influence the decision to keep or dispose of property.

If you have moved permanently to Portugal and your UK property is no longer a long term family base, it may be worth reviewing whether retaining it is still optimal from an estate planning perspective.

10) Wills and succession, align UK and Portuguese planning Many expats have an old UK will that does not reflect their Portugal life. Common issues include:

• Assets in Portugal not mentioned clearly, leading to administrative delays.
• Conflicting wills, where a Portugal will unintentionally revokes a UK will or vice versa.
• Beneficiaries or executors who struggle to deal with cross border administration.

Portugal is subject to EU succession rules that can apply to habitual residence, while allowing elections for the law of nationality in certain cases. This is a legal area rather than a pure tax issue, but it directly affects how smoothly your estate passes and can influence tax outcomes. Coordinating wills, powers of attorney, and beneficiary nominations is often as important as the tax planning itself.

11) Trusts and offshore structures, proceed carefully Trusts can be valuable in some UK estate plans, but for UK expats in Portugal they must be handled with caution. UK anti avoidance rules, reporting, and ongoing compliance can be complex. Portugal may also treat trusts differently than the UK and the interaction can create unexpected tax outcomes.

Trust planning is highly fact specific. If you are considering it, it is usually best to start with your objectives, family circumstances, and asset map, then model outcomes under both UK and Portuguese rules before implementing anything.

12) A practical checklist for UK expats in Portugal

• Confirm your domicile position: document your facts, intentions, and timeline, do not rely on assumptions.
• List assets by location and type: UK property, UK investments, pensions, Portugal property, bank accounts, life assurance, business interests.
• Estimate IHT exposure: include the NRB, RNRB, spouse exemptions, and any reliefs, also consider previous gifts.
• Review pension nominations: ensure they match your plan and that beneficiaries can receive benefits efficiently.
• Check ownership structures: especially for UK property and investment accounts.
• Review wills and executors: ensure UK and Portugal documentation is consistent and operationally workable.
• Plan liquidity: consider how any UK IHT bill would be paid without forcing distressed asset sales.
• Understand Portugal Stamp Duty: identify whether any non exempt beneficiaries are likely to inherit Portuguese assets.

Common misconceptions to avoid

• Misconception: If I pay tax in Portugal, the UK cannot tax my estate. Reality: UK IHT can apply based on domicile even if you are fully taxed in Portugal on income.
• Misconception: Living abroad for a few years removes UK IHT. Reality: domicile often persists, and deemed domicile can apply depending on residence history.
• Misconception: Having a UK will is enough. Reality: cross border assets frequently require coordinated UK and Portuguese legal planning.
• Misconception: UK pensions are always outside IHT. Reality: many are, but scheme rules, nominations, and withdrawals can change outcomes.

When to get advice You should consider specialist advice if any of the following apply:

• You own UK property, directly or through a company.
• Your family situation is blended, with children from previous relationships.
• You expect to leave assets to non direct descendants or non family members.
• You have significant pensions and are deciding how much to draw while in Portugal.
• You have made large gifts, or you are planning to make them.
• Your estate is likely to exceed UK IHT allowances.

Bottom line For many UK expats in Portugal, UK inheritance tax still applies, often on a worldwide basis, because domicile and deemed domicile rules continue to connect you to the UK system. Portugal may also impose Stamp Duty on Portuguese assets in some beneficiary scenarios. The most effective approach is to clarify domicile status, map assets by location, align wills and beneficiary designations, and build a plan that is compliant and practical across both jurisdictions.
