The UK inheritance tax system underwent a seismic shift on 6 April 2025. The domicile and deemed domicile regime, which had governed liability for decades, gave way to a straightforward long-term residence model. Under the previous system, an individual could leave the UK physically yet remain domiciled there for tax purposes, indefinitely triggering UK IHT exposure on worldwide assets. This created significant planning opportunities, but it also produced considerable uncertainty, particularly for career expatriates.
The new framework establishes a clear residence-based test. An individual is considered a long-term UK resident, a framework detailed in our guide to UK IHT After the 2025 Domicile Reform: Complete Expat Guide if they have been a UK resident for at least ten of the previous twenty tax years. During the first nine years of non-UK residence following departure, you remain liable for UK IHT solely on UK-situated assets. From year ten onwards, the scope broadens considerably: worldwide assets fall within UK IHT jurisdiction.
Crucially, the reform introduces what practitioners term the "IHT tail." Upon leaving the UK, you remain exposed to UK inheritance tax on worldwide assets for between three and ten years, depending on your previous UK residence period. Those who spent between ten and thirteen years in the UK face a three-year tail. For each additional year of UK residence (up to the maximum of ten years total exposure), the tail extends by one further year. An individual resident in the UK for twenty years, by contrast, carries a ten-year worldwide IHT exposure after departure.
For British expatriates in Spain, this creates a defined planning window. Your exposure to UK IHT on Spanish assets is quantifiable and finite, provided you satisfy the conditions for removing long-term residence status.
Whilst the UK has consolidated its inheritance tax system, Spain maintains a fragmented approach. Succession tax in Spain, formally the Impuesto sobre Sucesiones y Donaciones (ISD), operates at both national and regional level, with seventeen autonomous communities retaining considerable discretion over rates, allowances, and reliefs.
At the national baseline, Spanish succession tax applies progressive brackets ranging from 7.65% to 34%, with the tax burden falling entirely on the beneficiary rather than the estate. This represents a fundamental structural difference from UK inheritance tax, where the estate typically bears the charge. Children receive a baseline national allowance of €15,956.87, with adult children, spouses, and parents receiving similar entitlements. Yet these national figures serve as mere starting points; the real tax burden depends significantly on regional location.
Regional variations are substantial and merit detailed attention. Madrid has established itself as the most attractive jurisdiction, offering 99% relief on both inheritances and lifetime gifts for Group I beneficiaries (spouses, descendants, and ascendants). This effectively eliminates succession tax in practice for immediate family. The Balearic Islands similarly provide 100% bonification to spouses and direct descendants for inheritances, a relief extended from 2023. Valencia applies 99% bonifications to inheritances received by spouses, ascendants, and descendants, with matching relief for donations.
Andalusia, by contrast, offers a different structure. Rather than percentage-based bonifications, it provides an absolute allowance of €1,000,000 tax-free for Group I beneficiaries before tax calculation begins. For inheritances exceeding this threshold, progressive tax rates apply. Catalonia maintains more traditional rates without equivalent bonifications, making it materially more expensive for inheritance transfers.
These regional variations create substantial planning opportunities. Two beneficiaries inheriting similar Spanish properties may face vastly different tax bills depending on location. A property inheritance in Madrid incurs minimal tax for family members, whilst the identical inheritance in Catalonia triggers significant succession duties.

One of the most significant constraints on estate planning flexibility in Spain is the forced heirship rule, known as legitima. This doctrine mandates that a substantial portion of your estate is automatically reserved for designated family members, regardless of your testamentary wishes. Understanding and managing this restriction is essential for cross-border estate planning.
Under Spanish inheritance law, the estate is divided into three theoretical thirds. Two-thirds are allocated to forced heirs, whilst the remaining third may be freely distributed at your discretion. The first third (tercio de legítima estricta) must be equally distributed among your children or descendants. The second third (tercio de mejora) may be allocated to descendants, but the testator retains discretion over distribution, it may be given equally, unequally, or concentrated on particular individuals.
Forced heirs themselves are clearly defined: children and descendants have priority claims against parents and ascendants; in the absence of these, parents and ascendants may claim against their descendants; widows retain residual forced heirship rights. This framework cannot be altered by will for Spanish nationals or EU citizens resident in Spain who elect Spanish law to govern their succession.
However, a critical exception exists for non-Spanish nationals. Under Article 22 of EU Regulation 650/2012, British expatriates retain the ability to elect their home country's inheritance law to govern their Spanish estate, provided this election is clearly articulated in their will. By selecting English or Scots law in your testamentary document, you may bypass forced heirship entirely and dispose of your worldwide estate according to your personal wishes. This provision is transformative for British expats, permitting testamentary freedom unavailable under Spanish law alone.
The election must be explicit and unambiguous. Vague references to "English law" or "UK jurisdiction" may not suffice; the will should specifically state that the succession is to be governed by the law of England, Scotland, Wales, or Northern Ireland as appropriate. With this election in place, forced heirship does not apply to your assets, whether situated in Spain or elsewhere, providing comprehensive planning flexibility.
The intersection of UK and Spanish tax regimes creates potential for double taxation on the same assets. The estates of British expatriates may face UK inheritance tax on the worldwide estate (subject to the IHT tail limitation) whilst simultaneously incurring Spanish succession tax on assets situated in Spain. Without mitigation, this cascade could be punitive.
Spain and the UK maintain a comprehensive double taxation treaty governing income and capital gains, though inheritance and succession tax falls outside this instrument's scope. However, Spanish law itself provides a mechanism for credit relief. Spanish tax authorities permit a foreign tax credit for inheritance taxes paid to other jurisdictions on the same underlying assets. The credit is calculated as the Spanish tax attributable to the foreign property, multiplied by the ratio of foreign tax actually paid to the foreign tax that would have been payable.
This credit mechanism operates within important constraints. It applies only to taxes specifically denominated as inheritance or succession taxes; other levies do not qualify. The credit cannot exceed the Spanish tax due on the relevant assets. Furthermore, the credit applies only where the deceased was a tax resident of the foreign jurisdiction at the time of death; non-residents typically gain no relief.
For British expats in Spain, practical application requires careful planning. If your estate faces both UK IHT at 40% and Spanish succession tax (rates varying regionally from near-zero in Madrid to 34% in some circumstances), the interaction of the two systems demands attention. Strategic asset location becomes relevant: maintaining substantial UK assets may trigger UK IHT but secure foreign tax credit relief against Spanish taxes, whereas concentrating assets in low-tax Spanish regions (particularly Madrid) may minimize aggregate exposure.
The EU Succession Regulation 650/2012 further influences the framework. This regulation, which UK citizens continue to benefit from despite Brexit, permits choice of law elections in wills. By selecting English law for succession purposes, you establish a clearer legal pathway through Spanish courts and secure recognition of your testamentary intentions across EU member states, including Spain.
For British expatriates in Spain, retained UK assets present a particular tax challenge under the new residence framework. Any real property, personal property, or financial assets situated in the United Kingdom remain subject to UK inheritance tax regardless of your residence abroad, your domicile status, or the length of time you have spent outside the UK.
This exposure is absolute and permanent. A property inherited by your estate in London, a commercial property in Scotland, UK pensions, UK-held securities, or UK bank accounts all fall within UK IHT scope at 40% above the nil-rate band (£325,000 as at 2026). This applies even if you departed the UK thirty years ago and have never intended to return.
Some relief mechanisms exist but are narrowly circumscribed. Business property relief and agricultural property relief may reduce IHT liability on qualifying UK assets, but these operate at fixed percentages (50% or 100% depending on asset type and tenure) rather than eliminating tax entirely. Spousal exemptions remain available; assets passing to a surviving spouse incur no IHT, though the exemption does not extend to unmarried partners or unrelated beneficiaries. Charitable gifts secure full relief from IHT, permitting tax-efficient philanthropic planning where family circumstances permit.
For many British expats, the practical implication is that (alongside Capital Gains Tax for British Expats in Spain considerations) gradual disposal or redistribution of UK assets during lifetime may prove more tax-efficient than retaining them until death. Lifetime gifts to children or grandchildren incur no inheritance tax (provided the donor survives seven years after the gift), whereas retention pending death locks in 40% tax exposure. Conversely, some expatriates may intentionally retain modest UK assets as anchors to extended family networks or as part of deliberate cross-border planning structures.
Pensions present particular complexity under 2027 changes. From 6 April 2027, unused pension funds and death benefits will be included in the estate for UK IHT purposes, representing a significant expansion of the IHT net. British expats with substantial UK pensions now face immediate planning pressure to consider pension drawdown, lump sum transfers to beneficiaries where permitted, or strategic relocation of pension values to Spanish structures where available.
The April 2025 transition from domicile to residence-based taxation created a singular planning opportunity for expatriates. Those who had been non-resident in the UK but retained domicile status found their IHT exposure suddenly quantified and time-limited under the new regime. Rather than indefinite worldwide IHT exposure, they now benefit from the finite IHT tail mechanism.
For those who departed the UK before 2015, the new regime likely proves advantageous. Consider an individual who left the UK in 2000 and has remained non-resident for twenty-five years. Under the previous domicile regime, they carried perpetual UK IHT exposure on worldwide assets. Under the new residence-based framework, their IHT tail expired years ago; they now face UK IHT only on UK-situated assets, with Spanish assets protected by Spanish succession tax alone. This represents a material improvement in their tax position.
Conversely, those who departed the UK recently (post-2015) now face expanded exposure. An individual who left in 2023 and is now in 2026 is only three years into their post-UK residence period. Assuming fifteen years of prior UK residence, they carry a seven-year IHT tail extending to 2030. During this period, their Spanish property, Spanish bank accounts, and Spanish business interests all fall within UK IHT scope.
These distinctions generate practical planning requirements. For long-term expatriates, the new regime permits clarity and relaxation; no estate plan review is required beyond routine updates. For recent departures, immediate planning becomes urgent. Strategies might include strategic lifetime gifting of Spanish assets to reduce the taxable estate, establishing Spanish structures (such as limited liability companies) to hold property, establishing family foundations, or rationalizing portfolio structure to minimize worldwide IHT exposure during the tail period.
Documentation of the transition also matters. Clear evidence that you have left the UK and established Spanish tax residence becomes important for distinguishing between pre- and post-tail periods. Spanish tax residence certificates (certificado de residencia), NIE registration, and utility accounts should be retained as evidence of the transition date.

British expatriates in Spain operate within a complex reporting framework. The Spanish Modelo 720 (Annual Report of Assets Held Abroad) requires that residents with non-Spanish financial assets exceeding €50,000 report their location, nature, and value to Spanish tax authorities. This reporting obligation, separate from income tax or succession tax calculations, creates administrative burden and enhances tax authority visibility of your worldwide assets.
For estate planning purposes, the Modelo 720 serves as an inadvertent inventory of your Spanish-resident's assets at death. Spanish authorities have complete visibility of your financial position and asset location. This transparency, whilst administratively burdensome during lifetime, actually benefits estate planners; it ensures that Spanish probate authorities have accurate information regarding the full estate value when assessing succession tax liabilities.
Breaches of Modelo 720 reporting carry significant penalties. Failure to report triggers financial penalties ranging from €10,000 upwards, assessed per year of non-compliance. For those with material undisclosed assets, penalties can be severe. Equally important, undisclosed assets flagged during post-death probate proceedings can trigger enhanced penalties and reputational consequences for your heirs.
For estate planning purposes, ensuring current Modelo 720 compliance is foundational. Any estate plan should be predicated on full disclosure of assets. Working backwards from the Modelo 720 itself, your estate plan should identify assets already disclosed and ensure that any new acquisitions are properly reported in subsequent filings. This discipline, though administratively demanding, provides clarity for heirs and eliminates surprise tax exposure post-death.
Pensions and life insurance occupy special status in cross-border estate planning. For UK pension holders, the 2027 inclusion of death benefits in the IHT estate represents a watershed moment. Hitherto, unused pension funds could pass to beneficiaries free of UK inheritance tax (subject to income tax on withdrawals). From 6 April 2027, this relief expires. Death benefits become taxable estate assets, subject to 40% IHT above the nil-rate band.
This expansion creates immediate planning pressure, discussed comprehensively in How the 2027 Pension IHT Changes Affect British Expats. British expats with material UK pension values now face a choice: maintain pensions and accept future IHT at 40%, or implement pension planning strategies during lifetime. Options include full pension drawdown and reinvestment of proceeds in lower-tax structures, pension lump sum transfers to qualifying beneficiaries where plan rules permit, or strategic pension annuitization. Each approach carries tax and personal security implications; professional advice tailored to individual circumstances becomes essential.
Spanish life insurance products present an alternative vehicle. Spanish life insurance policies (pólizas de seguro) may be structured to pass death benefits directly to named beneficiaries outside the estate, avoiding inclusion in the succession tax base. These products are not subject to Spanish succession tax when death benefits are payable to named beneficiaries, though income tax (IRPF) may apply on investment gains within the policy during lifetime. For British expats, establishing Spanish life insurance policies alongside or instead of retaining UK pensions offers estate planning flexibility.
Simultaneously, the EU Succession Regulation permits nomination of beneficiaries in designated succession vehicles. Whilst not strictly pensions or insurance, beneficiary-designated accounts (where available under Spanish law) may serve similar functions. The interaction between UK IHT rules, Spanish succession tax, and Spanish insurance regulation requires careful co-ordination; strategies implemented without full cross-border awareness may create unintended tax consequences.
Lifetime gifts of insurance policies themselves offer additional planning opportunities. Under UK inheritance tax rules, a policy gifted to a beneficiary more than seven years before death passes free of IHT. This "seven-year rule" applies to life insurance just as to other assets. For expatriates with substantial life insurance, early gifting to children or grandchildren removes the policy value from the taxable estate, provided the donor survives the seven-year period.
Creating a valid will for cross-border assets requires simultaneous compliance with UK and Spanish formality requirements. A will valid in England must also satisfy Spanish probate authorities if Spanish assets are to pass under its terms. Conversely, a Spanish will (escritura pública) prepared before a Spanish notary may lack legal effect in English probate courts without additional authentication.
The safest approach involves creating parallel wills: one English will governing UK and worldwide assets under English law, and one Spanish testamentary document governing Spanish assets under Spanish law. This permits explicit choice of law elections in each document, ensuring that each jurisdiction's courts recognise the testator's intentions and the applicable legal framework without ambiguity.
When creating an English will for use in Spain, the document must explicitly elect English law as the governing law for succession purposes. This election, made under Article 22 of EU Regulation 650/2012, ensures that Spanish courts recognise the will as valid and apply English succession law rather than Spanish forced heirship rules. The election should be unambiguous and prominently stated early in the will document. Solicitors experienced in cross-border estate planning should draft these provisions; vague or ambiguous language may create disputes in Spanish probate proceedings.
Spanish testamentary documents, whilst enforceable in Spain, may require separate probate procedures in the UK for UK assets. This creates practical complexity but avoids the worst outcome: having one jurisdiction refuse to recognise your will altogether. With parallel wills prepared by advisers experienced in cross-border work, both jurisdictions typically co-operate in administering the estate.
The European Certificate of Succession, established under Regulation 650/2012, further simplifies cross-border probate. This certificate, issued by the jurisdiction where the deceased was habitually resident, provides proof of succession rights and is recognised across EU member states. For British expats in Spain who can establish habitual residence in Spain at death, the ECS substantially simplifies asset transfers to beneficiaries across borders.
