Spain inheritance tax (Sucesiones) — the region-by-region reality

Britons coming to Spain almost universally underestimate this tax because the mental model from UK IHT doesn't fit. Four critical differences:

1. Tax falls on the heir, not the estate. Each beneficiary calculates their own tax bill based on what they personally receive. A £2m estate split equally between three children produces three separate small-ish bills; the same estate going wholly to one child produces one large bill.
2. Spouses are not exempt. UK IHT exempts transfers between spouses entirely. Spanish Sucesiones taxes the surviving spouse on what they inherit — Group II under the relationship scale, with regional bonificaciones determining the actual bill.
3. Lifetime gifts are taxed. Donaciones (gifts) are taxed under the same system — there's no UK-style 7-year rule. Spanish tax residents pay on gifts received from anywhere; non-residents pay on Spanish-situs gifts.
4. No nil-rate band equivalent. Allowances are by Group (relationship) and region, not a per-estate threshold. A €200k inheritance can be tax-free for a child in Andalucía but generate €15,000+ tax for the same child in Cataluña.

Sucesiones runs the calculation in two steps. First, the state scale on the taxable base after personal allowance:

• Up to €7,993: 7.65%
• €7,993 – €15,980: 8.5%
• €15,980 – €23,968: 9.35%
• €23,968 – €31,955: 10.2%
• (continues progressively…)
• €398,778 – €797,555: 29.75%
• Above €797,555: 34%

Then a relationship multiplier is applied. The four Groups:

• Group I: children, grandchildren under 21 — multiplier 1.0×, large personal allowance
• Group II: children/grandchildren 21+, spouses, parents/grandparents — multiplier 1.0×, smaller personal allowance
• Group III: siblings, aunts/uncles, nephews/nieces, in-laws — multiplier 1.5× to 1.9× depending on pre-existing wealth
• Group IV: all other relatives or unrelated parties — multiplier 1.9× to 2.4×

After the multiplier, regional bonificaciones (rebates) apply on the resulting bill. This is where the regional variation explodes.

For Group I and II (spouse, children, parents) inheritances — the most common British case — current 2026 regional positions:

• Madrid: 99% bonificación on the resulting tax for Groups I & II. Effectively zero in most cases.
• Andalucía: Effectively 0% for Groups I & II after the 2023 reform raising the personal allowance to €1m per Group I/II beneficiary.
• Balearic Islands: 100% reduction for Groups I & II inheritances — effectively zero.
• Canary Islands: 99.9% reduction for Groups I & II — effectively zero, one of the most generous regimes.
• Valencia: 99% bonificación for Groups I & II plus a €100,000 tax-free allowance — effectively close to zero for most family inheritances.
• Cantabria: 100% reduction for Group I (children under 21); 100% for Group II (spouses, adult children) above certain conditions.
• Galicia: Significant reductions for Groups I & II.
• Murcia: 99% bonificación for Groups I & II.
• Cataluña: No 99% rebate. Standard allowances of €100,000 for spouses/children plus age-based reductions. Tax bills on €500,000+ inheritances can reach €30,000-€80,000 for a child or spouse.
• Asturias: Low allowances, limited bonificaciones — historically among the most punitive regions for Sucesiones.
• Aragón, Castilla-La Mancha, Castilla y León, Extremadura, La Rioja: Various intermediate positions; mostly favourable for Groups I & II but less than Madrid/Andalucía.
• Basque Country and Navarra: Foral regimes — own rules, generally favourable.

Regional rules change frequently; the headlines above reflect 2026 positioning but always confirm current-year specifics with a Spanish asesor when a real inheritance triggers.

The most common British scenarios that trigger Sucesiones:

1. UK parent dies, Spanish-resident child inherits. Spanish resident heir pays Sucesiones on the worldwide value received. UK estate may pay UK IHT on the same assets — the UK-Spain double tax treaty does not cover inheritance taxes specifically, but unilateral relief (under Article 23 of the Spanish Sucesiones law) allows Spain to credit UK IHT paid against the Spanish bill.
2. British couple resident in Spain, one spouse dies. The surviving spouse pays Sucesiones on what they inherit. UK IHT does not apply to assets passing between UK-domiciled spouses, but Spanish Sucesiones does. In Madrid/Andalucía/Valencia, post-bonificación this is usually small. In Cataluña or Asturias, it can be a six-figure bill.
3. British parent dies leaving Spanish property to UK-resident child. Non-resident child pays Sucesiones on the Spanish property only, applying the regional rules of where the property is located (since 2018 ECJ case C-127/12). UK IHT also applies; the unilateral relief mechanism applies.

The UK domicile question still matters for UK IHT exposure. Becoming Spanish-resident does not automatically change UK domicile (which has its own test — see HMRC's domicile guidance). HNW British movers should expect UK IHT to apply to UK-situs assets for a minimum of three further UK tax years after becoming Spanish-resident, and longer if domicile of origin remains UK.

• Regional choice matters more for HNW Brits than they think. A £2m estate passing to a Spanish-resident child generates ~zero Sucesiones in Madrid/Andalucía/Balearics and €200k+ in Cataluña. This single tax can outweigh decades of Patrimonio savings.
• Lifetime gifting (Donaciones) is taxed the same. You can't use UK-style 7-year survivorship to gift around Sucesiones — Donaciones is the same tax on the same scale.
• Spanish wills are advisable. Article 9 of the Spanish Civil Code lets British nationals choose UK succession law to apply to their Spanish estate (via EU regulation 650/2012, still recognised in Spain post-Brexit for Britons by treaty). This affects who inherits, not how much Sucesiones is charged — but a properly drafted Spanish will reduces probate friction significantly.
• Pension wrappers may help. Some Spanish-qualifying pension structures pass to nominated beneficiaries outside Sucesiones. The cross- border interaction with UK SIPP/QROPS is complex and worth specialist advice.
• Insurance-based structuring (seguros de vida) is the most commonly used approach by HNW Spanish residents to reduce Sucesiones exposure on liquid wealth. The Spanish life insurance industry has products designed specifically for this; the playbook walks through which are worth considering.
