Inheritance and Gift Tax in Spain

What the Impuesto sobre Sucesiones y Donaciones covers

The ISD is a single tax with two faces. When someone dies, their heirs pay it on what they receive, which is the inheritance side. When someone gives away money or property while still alive, the person who receives the gift pays it, which is the donación side. It is always the receiver who is taxed, never the estate itself, so each heir or each child is assessed separately on their own share.

The state sets a general framework: a set of reductions based on how you are related to the deceased, a rate that climbs from 7.65% up to 34% as the amount grows, and multiplier coefficients that push the bill higher for distant relatives and larger pre existing wealth. But the seventeen comunidades autónomas are allowed to improve on all of it, and most of them have, which is why the region matters more than the national rules.

Why the region decides what you pay

Spain hands inheritance and gift tax to the regions to administer, and they compete on it. In Andalucía and Madrid a child inheriting from a parent effectively pays close to nothing, because those regions layer generous allowances on top of a 99% discount on whatever tax remains. In other regions the same inheritance can produce a real bill. The connecting point that decides which region applies is usually where the deceased lived, or, for a property, where the property sits. Getting this right is the single biggest factor in the final number.

This is also why a Spanish will matters. A clear will keeps the estate moving through the Registro Civil and the notary without the delays that eat into the six month filing window.

The four groups of relatives

Everything in the ISD flows from which group you fall into. Group I is descendants under 21, who get the largest state allowance. Group II is descendants of 21 and over, spouses, and parents. Group III is brothers and sisters, uncles, aunts, nephews and nieces. Group IV is cousins, unrelated partners without a registered link, and everyone more distant, who get no state reduction and face the steepest multipliers. The closer your group, the more the regional discounts do for you. Registered partners, or pareja de hecho, are treated like spouses in some regions and not in others, which is a trap worth checking before you assume you are covered.

Non residents now get the regional rules too

For years, non residents were forced onto the harsher state rules while residents enjoyed the regional discounts. That ended. The Court of Justice of the European Union struck the discrimination down in 2014, the Spanish Supreme Court extended the same protection to residents of non EU countries, and Ley 11/2021 wrote it all into law. Today any heir or gift receiver, whether they live in the Netherlands, Germany, the United Kingdom or anywhere else, can apply the regional reductions and bonificaciones on Spanish assets. Non residents do need to appoint a representative in Spain to deal with the Agencia Tributaria, and anyone who overpaid under the old state only rules may be able to reclaim the difference.

Gifts are taxed too, and they carry extra costs

Handing property to your children during your lifetime, a donación, is often pitched as a way to sidestep inheritance tax. Sometimes it works, but it is never free. The child pays gift tax in the region where the property sits, and the parent can face a capital gain in their own income tax, the IRPF, on the rise in value since they bought it. On top of that comes the plusvalía municipal, the town hall tax on the increase in urban land value. Whether gifting beats inheriting depends entirely on the region and the numbers, which is why it deserves its own careful look rather than a rule of thumb.

The taxes that ride alongside the ISD

Inheritance and gift tax rarely arrive alone. Heirs and gift receivers of urban property also meet the plusvalía municipal, and gifts can trigger a capital gain in the giver's IRPF. Weighing all of them together, against the valor catastral used to value the property, is what turns a rough estimate into a reliable one.
