As a UK expatriate living in Portugal, inheritance tax planning is anything but straightforward. Portugal offers an attractive lifestyle and a favourable tax environment, but failing to plan ahead could see a significant portion of your hard-earned assets eroded by inheritance taxes. The implications are real, and the strategies to reduce your tax burden are worth knowing.
Things get more complicated when you’re dealing with two different tax systems at once. Many UK expats who’ve obtained residency through the Portugal Golden Visa programme or other routes tend to underestimate proper inheritance tax planning until it’s too late.
What is Inheritance Tax in Portugal?
Inheritance tax in Portugal was formally abolished in 2004. In its place, a stamp duty known as Imposto do Selo applies to the transfer of assets upon death or through gifting. The exemptions vary depending on the relationship between the donor and the recipient, whilst the rate for non-exempt beneficiaries is a flat 10% on Portuguese-situated assets.
For UK expats in Portugal, the interaction between Portuguese and UK inheritance tax rules matters a great deal, since your domicile status can significantly affect your tax liability. Portugal’s Imposto do Selo applies at a flat rate of 10% on Portuguese-situated assets transferred to non-exempt beneficiaries. Spouses, direct descendants, and ascendants are fully exempt, whilst all other beneficiaries face the flat 10% rate.
One significant advantage of the Portuguese system is that spouses and direct descendants (children and grandchildren) benefit from complete exemption from inheritance tax on most assets. Compared to many other European jurisdictions, that’s a considerable advantage.
Understanding the UK-Portugal Tax Treaty
The double taxation agreement between the UK and Portugal determines which country has the primary right to tax your estate. Under this treaty, immovable property (such as real estate) is typically taxed in the country where it’s located, whilst movable assets are generally taxed in the country of the deceased’s domicile at the time of death.
The treaty helps prevent the same assets from being taxed twice, but it doesn’t wipe out your tax obligations entirely. How it applies to your specific situation is something worth working through carefully as part of retirement planning and estate management.
Domicile Status and Inheritance Tax
Your long-term UK residence status (not the same as your citizenship) now does much of the heavy lifting when it comes to UK inheritance tax obligations. Since 6 April 2025, the UK replaced the domicile test with a residence-based regime: if you have been UK tax resident for at least 10 of the previous 20 tax years, you are classed as a “long-term UK resident” and may be subject to UK inheritance tax on your worldwide assets, even while living in Portugal.
Conversely, if you are not a long-term UK resident, you will generally only be liable for UK inheritance tax on UK-situated assets. Portuguese stamp duty (Imposto do Selo) would then apply to assets located in Portugal for non-exempt beneficiaries.
Under the new residence-based regime in force from 6 April 2025, whether you remain within scope of UK IHT on your worldwide assets depends on your residence history — specifically, whether you have been UK tax resident for 10 or more of the previous 20 tax years. If you leave the UK as a long-term resident, a trailing exposure period of up to 10 years may apply. Taking advice on your specific residence count and IHT tail is strongly recommended.
Key Differences Between UK and Portuguese Systems
The contrast between the two systems is stark. The UK imposes inheritance tax at 40% on estates exceeding £325,000 (with additional allowances for main residences), whilst Portugal’s system is far more generous to family members.
In Portugal, the inheritance tax rates are:
Spouses and direct descendants: 0% (complete exemption)
Other beneficiaries (e.g. siblings, nieces/nephews, unrelated parties): flat 10% on Portuguese-situated assets
Non-relatives: Up to 10% or higher in certain circumstances
The UK system applies a flat 40% rate above the threshold, regardless of the beneficiary’s relationship to the deceased, though various reliefs and exemptions may apply.
How to Reduce Your Inheritance Tax Liability as a UK Expat in Portugal
It pays to work with a financial adviser. That said, the following strategies can help reduce your tax burden:
Strategic Gifting
In Portugal, gifts between spouses or direct descendants (children and grandchildren) are exempt from inheritance tax. For other recipients, tax may be applicable, and sticking to the gifting rules and time limits matters. Starting early and gifting regularly, taking advantage of annual exemptions and the seven-year rule in the UK system, is the approach that tends to work best.
Trust Structures
Setting up trusts can be an effective way to remove assets from your taxable estate. You’ll need professional advice to ensure compliance with both Portuguese and UK trust laws. Portuguese law doesn’t recognise trusts in the same way as common law jurisdictions, which can create complications that need careful handling.
Life Insurance Planning
Investing in life insurance policies can provide a tax-efficient way to transfer wealth to your beneficiaries. Life insurance proceeds are generally exempt from inheritance tax in Portugal when properly structured, making this an attractive option for wealth transfer.
Retirement and Pension Planning
Proper retirement planning, including the use of tax-advantaged accounts like Portuguese Pension Plans (Planos de Pensões), can help shelter a portion of your assets from inheritance tax. UK pension transfers to qualifying recognised overseas pension schemes (QROPS) have become significantly more restricted: from 30 October 2024 a 25% Overseas Transfer Charge applies to QROPS transfers to EEA countries and Gibraltar (unless the member is resident in the same country as the QROPS), and from April 2027 unused pension funds will be brought within the scope of UK inheritance tax. Professional advice is essential before considering a QROPS transfer.
Asset Structuring and Location
A financial adviser can help you look at asset structuring options, such as offshore holdings or company ownership, that may reduce your inheritance tax exposure. Where your assets are located can significantly affect which country’s inheritance tax rules apply, so getting that positioning right matters.
Common Pitfalls to Avoid
Many UK expats in Portugal make costly mistakes that proper planning would have prevented:
Assuming Portuguese residency eliminates UK tax obligations: since 6 April 2025, your UK tax residence history — specifically whether you have been UK tax resident for 10 or more of the previous 20 tax years — determines whether UK inheritance tax applies to your worldwide assets
Failing to update wills and estate planning documents: Portuguese law may not recognise certain provisions in UK wills
Overlooking the impact of UK property: retaining significant UK assets can trigger substantial inheritance tax liabilities
Inadequate record-keeping: failing to maintain proper documentation of your domicile intentions can be costly
The Importance of Cross-Border Tax Planning
Effective inheritance tax planning for UK expats in Portugal requires a solid grasp of both tax systems and how they interact. This is particularly true for those with significant assets in both countries or who maintain strong ties to the UK.
Planning should begin as soon as you establish Portuguese residency, whether through the Golden Visa programme, employment, or retirement. Delaying can severely limit your options and potentially result in unnecessary tax liabilities for your beneficiaries.

Professional Guidance is Key
Cross-border inheritance tax planning is genuinely complicated, and professional guidance isn’t just a nice-to-have. The interaction between UK and Portuguese tax laws, combined with the possibility of legislative changes in both countries, means expert advice can save your beneficiaries substantial sums.
Working with advisers who understand both systems and can coordinate planning across jurisdictions is the best way to get a good outcome. That includes making sure any planning strategies comply with both countries’ anti-avoidance rules and reporting requirements.
