Irish expats in Spain face Capital Acquisitions Tax (CAT) on the Irish side and Spanish IHT on the Spanish side. Ireland's CAT is charged on the recipient at 33% above group-specific thresholds; Spanish IHT is charged on the recipient at the relevant regional rate. Both taxes can apply to the same estate. Ireland/Spain double-tax relief and Brussels IV election manage both. We act for Irish expats from Costa del Sol to Costa Blanca to the Canaries.
The Irish expat community in Spain has grown significantly — particularly in the Costa del Sol, Costa Blanca, Valencia and Canaries. Combined with weekenders and regular travellers from Dublin, Cork and Galway who hold property in Spain, the Irish presence in Spanish inheritance files is substantial. The estate planning framework differs materially from the British position, because Ireland's CAT taxes the recipient rather than the estate, uses group-specific thresholds, and operates under a different treaty and credit architecture.
Ireland's Capital Acquisitions Tax applies at 33% on gifts and inheritances above group-specific thresholds: Group A (€335,000, children from parent), Group B (€32,500, siblings, nieces, nephews, grandchildren, parents from child), Group C (€16,250, all other). These thresholds are lifetime-cumulative: every taxable gift or inheritance from the same group is aggregated against the threshold. CAT applies where the disponer (deceased) is Irish-resident or Irish-domiciled, where the beneficiary is Irish-resident or Irish-domiciled, or where the asset is Irish-situated. In practice, Irish emigrants to Spain who retain Irish domicile frequently trigger CAT on their worldwide estate.
Spain's IHT applies under the relevant autonomous community regime. Ireland and Spain have a double-tax convention covering CAT and IHT — Convention for the Avoidance of Double Taxation with Respect to Taxes on Inheritances, signed in 1958 and still in force. The treaty provides credit mechanisms for Irish tax paid on Spanish-situated assets and vice versa, subject to conditions. This is an advantage not available to British or American expats.
This page covers Irish CAT mechanics for Spanish-situated assets, Ireland/Spain treaty relief, Brussels IV election for Irish nationals, the parallel probate procedure, and the specific planning levers available under Irish tax law for Spanish property.

Six rules govern every Irish-connected Spanish estate. Start here.
Irish Capital Acquisitions Tax at 33% above group-specific thresholds. Charged on recipient, not estate. Thresholds are lifetime-cumulative per group.
Recipient-basedGroup A: parent to child. Group B: close family (siblings, nieces, grandchildren). Group C: all other. Thresholds lifetime-cumulative.
Group-based thresholds1958 Convention covers CAT and Spanish IHT. Credit for Spanish tax paid on Spanish assets against Irish CAT. Treaty-based, not unilateral.
Treaty reliefIrish nationals elect Irish succession law on Spanish wills under EU Regulation 650/2012. Preserves Irish testamentary freedom across Spanish estate.
Succession law electionSpanish residents on worldwide; non-residents on Spanish-situated only. Regional election for non-resident Irish beneficiaries under 2014 ECJ principle.
Residence/situsIrish probate through the Probate Office or District Probate Registry. Spanish probate through Spanish notary. Parallel procedure, six-month Spanish deadline.
Parallel procedureIreland's Capital Acquisitions Tax is structurally different from estate-based systems (UK IHT, US Federal estate tax). CAT is charged on the beneficiary based on what they receive. Each beneficiary has their own group-specific lifetime threshold. Every taxable gift or inheritance they receive from the relevant group counts against that threshold. Once the threshold is used, CAT at 33% applies to the excess.
Example: an Irish-resident adult child inheriting €500,000 from an Irish-domiciled parent. Group A threshold: €335,000. Taxable slice: €165,000. CAT at 33%: €54,450. If the child has previously received taxable gifts from parents aggregating €100,000, the threshold remaining would have been €235,000, taxable slice €265,000, CAT €87,450. The lifetime-cumulative nature makes sequential planning important.
CAT applies where at least one of: (a) the disponer is Irish-resident, ordinarily-resident or Irish-domiciled; (b) the beneficiary is Irish-resident, ordinarily-resident or Irish-domiciled; (c) the property is Irish-situated. For Irish emigrants who have not formally shed Irish domicile, CAT follows the worldwide estate.
Irish domicile (like UK domicile) is a common-law concept: each person has a domicile of origin that persists unless replaced by a domicile of choice. Irish emigrants who move to Spain for retirement typically retain Irish domicile unless they actively replace it — which requires residence plus intention to remain permanently or indefinitely. Retention of Irish bank accounts, Irish family connection, Irish burial arrangement, expressed intention to return, or absence of clear evidence of intent to remain in Spain, typically preserves Irish domicile.
Irish domicile drives CAT exposure on worldwide estate. For Irish expats who have been in Spain 20+ years with substantive evidence of intent to remain, a domicile-of-choice argument can succeed — reducing CAT exposure to Irish-situated assets only (Irish bank accounts, Irish property retained, etc.). Planning this is possible but requires careful documentation. We coordinate with Irish tax advisers on the domicile analysis.
The 1958 Ireland/Spain Convention on inheritance tax is still in force and provides substantial relief for dual-exposure cases. Article IV gives taxing rights primarily to the state of domicile, with situs-state (Spain for Spanish-situated assets) retaining rights. Article VI provides a credit mechanism: where both states tax the same asset, the state of domicile credits the situs-state tax. For Irish-domiciled deceased with Spanish property, Irish CAT credits the Spanish IHT on that property.
In practice, the treaty credit is frequently under-used. Executors who file Irish CAT returns without claiming the Spanish credit overpay Irish CAT. We coordinate the filings to ensure the credit is properly claimed.
We confirm Irish domicile and residence status for the deceased and each beneficiary, classify CAT groups, screen threshold usage, and identify treaty credit opportunities.

Consider a typical Costa Blanca case: Irish-domiciled couple, one deceased, Spanish property worth €450,000, two Irish-resident adult children as equal beneficiaries. Each child receives €225,000 from the Spanish property plus any Irish assets. Against Group A threshold of €335,000 each, no CAT is due if the Spanish property is the only inheritance. If each child also inherits Irish assets of, say, €200,000 each, the total received is €425,000, exceeding the threshold by €90,000, CAT due €29,700 per child. Spanish IHT in Valencia post-2023: near zero. Treaty credit not material in this case because Spanish tax is near zero.
For a higher-value Marbella villa (€1.5m) with same structure: each child receives €750,000. Threshold used fully; taxable slice €415,000 per child; CAT €136,950 per child. Spanish IHT (Andalusia 99% reduction): a few hundred euros per child. Again treaty credit nominal.
The pattern: post-regional-reform Spain, Spanish IHT on Group II estates is typically a few hundred to a few thousand euros. Irish CAT on substantial inheritances above the threshold is the dominant tax. This reverses the British position (where UK IHT on spouse-inherited UK property engages spouse exemption) — in Irish cases each child beneficiary engages their own threshold, and high-value inheritances commonly overtop it.
Several structures can reduce Irish CAT exposure:
(1) Lifetime small gifts exemption: €3,000 per disponer per donee per year, tax-free and outside CAT aggregation. Over a decade, a couple can transfer €60,000 to each child tax-free.
(2) Favourite nephew/niece relief: nieces and nephews who worked substantially in the disponer's business can access Group A threshold instead of Group B for business-related assets.
(3) Business relief: 90% reduction on qualifying business assets passing to close family, subject to ownership conditions.
(4) Agricultural relief: 90% reduction on qualifying agricultural property passing to active farmers.
(5) Dwelling house exemption: exemption for inherited main home where beneficiary has occupied the property for 3 years and meets continuing occupation conditions. Narrow conditions but can be relevant for Spanish property where the beneficiary has lived there.
(6) Section 72 life assurance policies: life assurance written to fund CAT liability, exempt from CAT if properly structured. Common planning tool for Irish high-net-worth families.
For Irish expats in Spain 15+ years considering formal domicile shedding: (a) document intention to remain in Spain indefinitely (will provisions, burial arrangements, Spanish residency, property ownership, social and business connections in Spain); (b) reduce Irish footprint where feasible (close Irish bank accounts not essential, avoid UK-style "temporary return" visits, avoid owning Irish real estate beyond any required minimum); (c) consider obtaining a professional domicile opinion from Irish tax counsel. Post-shedding, Irish CAT exposure reduces to Irish-situated assets only. This is a multi-year planning process, not an event.
A common modern pattern: the Irish parent emigrated to Spain decades ago, shed Irish domicile, dies Spanish-domiciled; the children remained in Ireland. Irish CAT still applies because the beneficiary is Irish-resident. CAT on worldwide inheritance to Irish-resident recipient, at 33% above Group A threshold, with treaty credit for Spanish tax on Spanish-situated assets. Spanish IHT on non-resident Irish beneficiary of Spanish property applies at Spanish regional rates with regional election available. We file both sides.
Spanish wills for Irish testators follow the same dual-will pattern as British expats: Spanish will covering Spanish assets, Irish will covering Irish assets, each expressly preserving the other, Brussels IV election of Irish law in the Spanish will, bilingual drafting, Spanish notarial execution and Registro Central deposit. Irish wills should be drafted by Irish solicitors under Irish rules. We coordinate on both sides.
Irish probate: uncontested small estates through District Probate Registry; larger or contested through the Probate Office in Dublin. Grant of Probate or Letters of Administration issued. Timelines typically 6 to 16 weeks for uncontested. Spanish side: aceptación de herencia before Spanish notary, Modelo 650 filing within 6 months of death, Land Registry transfer. We run both sides in parallel.
Irish occupational pensions and PRSAs have complex death-benefit rules that interact unevenly with Spanish IHT. Lump-sum death benefits from Irish pensions passing to a Spanish-resident beneficiary may engage Spanish IHT under regional rules; may engage Irish CAT depending on structure. Approved Retirement Fund (ARF) inheritance has specific Irish tax consequences (income tax on beneficiary withdrawals) alongside any CAT. We screen pension structures on every Irish file.
For Irish clients considering the move to Spain, pre-move structuring delivers the best outcomes: review Irish estate plan to anticipate Spanish move, coordinate wills, plan asset holding structures, understand timing of residency establishment, plan use of CAT thresholds and lifetime gifts. For post-move planning, the key levers are Spanish-will preparation, Irish CAT domicile review at appropriate point, Spanish property valuation strategy, and coordination with Irish advisers on ongoing matters.
