Inheritance Tax in Spain: What Each Heir Actually Pays
Spain's inheritance and gift tax, ISD (Impuesto sobre Sucesiones y Donaciones), works differently from the UK or US: it is paid by each heir who receives, not by the estate. It is heavily devolved to the regions, so the bill swings enormously by autonomous community. This guide explains the 2026 essentials, then points you to our calculator and a free, no-commitment review.

How inheritance tax in Spain really works
Spain's ISD is one of the most misunderstood taxes for expats, because it does not behave like the inheritance tax most people know at home. There is no single estate that pays a bill before assets are shared out. Instead, every heir or beneficiary is taxed individually on what they personally receive, and how much they owe depends on their relationship to the deceased and, crucially, on which autonomous community's rules apply.
It is a state tax, but its application is heavily devolved to the comunidades autonomas, which set their own reductions and rebates. The result is that the effective bill on the same inheritance can vary enormously from one region to another. The figures below are general guidance for 2026; regional rules shift, so always confirm the current position with the Agencia Tributaria (AEAT) and the relevant comunidad before you act.
The rules that decide your ISD bill
A handful of factors drive what each heir pays: who they are, where the deceased and the assets were, and which regional rules apply. Here is how they fit together.
Paid by each heir, not the estate
Unlike the UK or US, Spain does not tax the estate as a whole. Each heir or gift recipient is taxed on their own share, on a personal sliding scale. Two people inheriting from the same person can pay very different amounts depending on their relationship and their own circumstances, so ISD is always assessed beneficiary by beneficiary.
Heavily devolved to the regions
ISD is a state tax that the autonomous communities largely administer, each setting its own reductions, allowances and rebates (bonificaciones). The same inheritance can produce a modest bill in one comunidad and a heavy one in another, which is why the region that applies matters as much as the amount inherited.
Heir groups I to IV
Heirs fall into four groups: Group I (descendants under 21), Group II (descendants 21 or over, spouses and ascendants), Group III (siblings, nieces, nephews and in-laws) and Group IV (cousins, unrelated heirs and more distant relations). Allowances are largest for Groups I and II and shrink toward Group IV, where there is little or no personal reduction.
Non-residents can use regional rules
Since the EU Court ruling and subsequent Spanish doctrine, non-residents, including those outside the EU, can generally apply the relevant autonomous community's rules instead of the harsher state-only regime. That can mean a meaningful saving, but the right comunidad and the paperwork matter, so confirm your case with a gestor or tax adviser.
Residents vs non-residents on what is taxed
Residents in Spain are taxed on their worldwide inheritance, while non-residents are taxed only on Spanish-situated assets, such as a property or a bank account here. Where you are resident therefore changes not just the rate but the very scope of what Spain can tax.
How we help families through ISD
Inheritance is rarely just a tax form. We help expat families understand their exposure, apply the right regional rules and meet the deadlines, calmly and in plain language.
Group and region review
We identify each heir's group (I to IV) and the autonomous community whose rules apply, so the correct reductions and rebates are claimed rather than the default state regime.
Modelo 650 and 651 filing
We prepare and file the Modelo 650 for inheritances and the Modelo 651 for lifetime gifts, gathering the valuations and documents each requires.
Estimate before you commit
We run the numbers with you, alongside our inheritance tax calculator, so you have a realistic figure per heir before any decision, not a surprise afterwards.
Non-resident coordination
For heirs living abroad we apply the relevant regional rules where allowed and coordinate the Spanish filing with your home-country obligations.
Valencia region guidance
We keep track of the current Comunitat Valenciana rebates for close relatives and apply them correctly, while flagging that regional figures can change year to year.
Deadline and extension support
The standard deadline is six months from death, with an extension possible if requested in time. We track it for you so the return is filed and penalties avoided.
Your free first consultation
Start with a free, no-commitment review. It is a straightforward conversation to map who inherits, which region applies and what each heir is likely to owe, before you commit to anything.
