Regional IHT Comparison Estate Planning & Inheritance in Spain — Spain/Spain Coordinated

Since the 2014 European Court of Justice ruling in Commission v Spain (Case C-127/12), non-resident EU and EEA heirs have the right to apply the regional bonificación of the autonomous community where the Spanish assets are located, or where the deceased was habitually resident. This ended the discriminatory treatment that forced non-residents to pay the state rate while residents accessed regional reliefs. In 2018, the Spanish Supreme Court extended the same right to non-EU, non-EEA heirs (British, American, Canadian, Australian) on the basis of EU free movement of capital principles. All foreign heirs now have regional access.

The practical effect is that region selection is now the single most powerful planning variable in Spanish inheritance. A retired British couple with a €1.5m estate who relocate from Valencia to Madrid in the five years before death save their children approximately €180,000 in IHT. A family that keeps property in a high-tax region when they could credibly establish habitual residence in a low-tax region is leaving very large amounts of money on the table.

The regions divide roughly into three tiers. The near-zero tier (Madrid, Andalusia, Murcia, Cantabria, Galicia, Extremadura, Canary Islands) applies bonificaciones of 99% or more for Group I and II heirs (spouses, children, grandchildren, parents). The middle tier (Valencia, Balearics, Castilla-La Mancha, Aragon, La Rioja) applies substantial but not total relief, typically 50-75%. The higher-tax tier (Catalonia, Asturias, Basque Country in some cases, Castilla y León) applies more limited relief and taxes larger estates meaningfully.

This page compares all 17 autonomous communities for the two most common heir classes — spouses (Group II) and children (Group II) — and explains the planning levers: habitual residence tests, five-year rule, Brussels IV interaction, and what to do when the deceased's residence changes in the final years of life.

Spanish inheritance tax by region: the comparison explained

Spain's 17 autonomous communities each set their own IHT reductions and bonificaciones. This has produced a patchwork where the tax on an identical estate varies from essentially zero to six-figure sums depending on where the deceased died. For cross-border families, understanding the regional map is the foundation of all subsequent planning. The variation is not marginal — it is often the single largest financial decision in the estate.

Madrid: the benchmark for zero IHT on direct lineage

Madrid's 99% bonificación for Groups I and II heirs applies after all reducciones. A €1m estate to one child, with the standard €15,956 Group II reducción, produces a taxable base of €984,044. State-schedule IHT on that base is approximately €175,000. The 99% bonificación reduces this to approximately €1,750. Effective rate: 0.17%. The same structure applies to spouses and grandchildren. Parents inheriting from deceased children access the same relief. Madrid has sustained this policy since 2007 across multiple regional governments.

There is no cap on the estate size at which the bonificación fails. A €10m estate to children attracts the same 99% relief, producing a headline IHT of €1.7m and an after-bonificación bill of €17,000. Madrid is therefore exceptionally favourable for larger estates — the bigger the estate, the more valuable the 99% relief.

Andalusia: the 2019 reform and its effect

Andalusia legislated a 99% bonificación for Groups I and II in 2019, matching Madrid. Before this, Andalusia was a middle-tier region and expat families in Marbella, Málaga, and the Costa del Sol routinely faced six-figure IHT bills. Post-2019, the same families pay essentially nothing. The reform is retrospective to all deaths after its commencement — families who inherited pre-2019 are not affected, but all current planning can assume Andalusian parity with Madrid.

For British expats along the Costa del Sol, this was a transformational change. The default assumption that retiring to southern Spain created a large IHT exposure for UK children is no longer correct. Combined with the UK-Spain treaty credit for any Spanish IHT paid, the structure is essentially neutral for families whose children remain UK-resident.

Murcia, Cantabria, Galicia, Extremadura, Canary Islands: the near-zero tier

These regions apply bonificaciones of 99% or near-equivalent for Groups I and II. The mechanics vary — some apply a fixed 99%, some a formula that produces near-99% in practice, some include generous reducciones that reduce the taxable base before the bonificación applies. The effective outcome is similar: parent-to-child and spouse-to-spouse inheritances attract minimal tax.

The Canary Islands are particularly favourable for retirees establishing residence there for tax purposes: combined with the island's separate IGIC VAT regime and IRPF differentials, the Canaries present one of the most complete expat tax packages in Spain. The catch is that the five-year habitual residence rule must be satisfied — a late-life move to the Canaries does not access Canarian relief if the deceased dies before the five-year threshold.

Valencia, Balearics, Castilla-La Mancha, Aragon, La Rioja: the middle tier

These regions apply substantial relief but not total. Valencia's 50% bonificación is typical. Balearic 99% bonificación for Group I and II was introduced in 2023 — the Balearics are now near-zero tier, but much planning still assumes pre-2023 position. Aragon's relief is more limited, particularly for Group III and IV. La Rioja and Castilla-La Mancha apply middle-tier structures with substantial but not complete relief.

The middle tier is where detailed calculation matters most. Headline bonificación percentages do not always reflect effective tax because reducciones, coefficient multipliers for heir's pre-existing wealth, and asset-type specific reliefs interact. A Valencia parent-to-child estate of €500,000 might produce effective IHT of €8,000-€15,000 depending on the heir's net worth and whether the primary-residence reducción applies.

Catalonia, Asturias, Castilla y León: the higher-tax tier

Catalonia has more limited bonificaciones than Madrid or Andalusia. Children and spouses face a progressive bonificación that starts at 99% for small estates and reduces as the estate grows. For very large estates, effective rates can approach 15-20%. Generous reducciones (up to €650,000 per direct descendant) soften this meaningfully, but for estates over €2m the Catalan tax is material.

Asturias and Castilla y León apply more limited reliefs. Effective rates on large estates can approach the state schedule — in the high teens or low twenties. For expats with significant wealth, dying resident in one of these regions is materially more expensive than dying resident in Madrid or Andalusia. Where the family retains genuine flexibility over residence, this is often the single most valuable planning decision.

The Basque Country and Navarra: foral regimes

The Basque Country and Navarra operate their own IHT regimes under historic foral law, separate from the state schedule. Each of the three Basque provinces (Álava, Bizkaia, Gipuzkoa) applies its own rules, and Navarra applies another set. Relief levels vary but are generally favourable for direct-line heirs — often 0% on inheritances between spouses and children in Bizkaia and Álava, with Gipuzkoa applying a modest rate and Navarra a progressive structure.

For families with foral connections (Basque or Navarrese vecindad civil), the foral IHT regime applies regardless of where the deceased dies. For families without foral connections who happen to die resident in a foral region, the foral regime applies by territorial rule. Specialist advice is essential — foral IHT is its own body of law.

The five-year habitual residence rule in practice

The region whose bonificación applies is determined by the deceased's habitual residence for the greater part of the five years preceding death. A move from Catalonia to Madrid two years before death does not access Madrid relief if Catalan residence dominates the five-year window. A move four years before death does access Madrid relief. This is the most commonly miscalculated aspect of regional IHT planning.

Residence is documented through padrón (municipal registration), tax residency certificate from AEAT, utility bills, healthcare enrolment, school enrolment for children. Spanish tax residency is a necessary but not sufficient condition — regional residence must be established within Spain. A Spanish tax resident who moves between Valencia and Madrid in their final years must document the greater-period residence carefully.

Asset location rules for non-resident deceased

If the deceased is not Spanish-resident, regional IHT is determined by the location of Spanish assets. A British owner of a Valencia apartment who dies resident in the UK triggers Valencian IHT on the apartment — Valencian bonificación applies. A British owner of a Madrid flat and a Costa del Sol villa triggers Madrid IHT on the flat and Andalusian IHT on the villa — two separate calculations, two separate Modelo 650 filings to two separate regional authorities.

This creates a planning lever for non-resident British, American, and other foreign owners: consolidate Spanish property in a low-tax region before death. Moving a property portfolio from Catalonia to Madrid or Andalusia in the years before death (via sale and reinvestment, or inter-vivos gift) can produce material IHT savings for non-resident owners.

Brussels IV interaction

Brussels IV governs succession law (who inherits what) but not IHT (what they pay). Regional IHT applies regardless of whether succession is under Spanish law or foreign national law. A British expat who elects UK succession law under Article 22 still pays Spanish regional IHT on Spanish assets. The Brussels IV election affects forced heirship but does not change the IHT calculation.

This matters because families sometimes assume that electing UK law removes Spanish IHT exposure. It does not. The UK-Spain position is governed by IRS treaty (limited) and by the UK's own IHT system, not by Brussels IV. Spanish IHT on Spanish assets is payable by all heirs, Spanish or foreign, resident or non-resident.
