Spanish inheritance tax: the calculator by region
Inheritance tax is regional in Spain — the same inheritance costs almost nothing in the Balearics, but a real 60% in Catalonia. Pick a region, see the relief.
In short
Is there a calculator for Spanish inheritance tax?
Yes — pick a region and see the relief for Group I/II heirs (children, spouses, parents), from 100% in the Balearics to a real sliding scale in Catalonia. Free to use.
Inheritance tax Spain: what does it show?
Only the regional relief applied to the tax already calculated under the state tariff — not a full inheritance tax calculation.
Does it replace a tax adviser?
No — the actual calculation in your case (allowances, prior wealth, exact valuation) belongs with your Spanish tax adviser.
How much inheritance tax will I pay on my Spanish property?
That depends almost entirely on the autonomous community, not the value alone. The Balearic Islands have applied a 100 percent relief with no cap for Group I and II (children, spouses, parents) since July 2023 — inheritance tax effectively disappears. Similarly favourable are the Canary Islands (99.9 percent), Andalusia and Valencia (99 percent each), and Madrid and Murcia (99 percent). Catalonia, by contrast, has no flat relief for adult children — a genuine sliding scale applies there, starting at 60 percent and falling to around 28.9 percent only at 3 million euros. What matters is the region holding the highest value of the Spanish estate, and the relief must be claimed within the filing deadline. As of: 27 July 2026, reviewed quarterly.

Your estimated inheritance tax
Inheritance tax, groups I and II (parents, children, spouses). Autonomous tax law changes; review quarterly. As of: 2026-07-27. For inheritance, the rules of the autonomous community holding the highest value of the Spanish estate apply. With a single Spanish property that is simply its region. The relief must be claimed within the filing deadline — miss it and it becomes contentious.

The relief is not an allowance
The word "allowance" is misleading for Spanish inheritance tax. What the autonomous communities have legislated is in most cases not a reduction of the taxable base but a relief applied to the tax already calculated: first the tax is worked out under the state tariff system, then the regional reduction is applied to it. That is why the same inheritance can cost almost nothing or a great deal depending on the region, even though the valuation of the property is identical.
The calculator above compares exactly that one lever — the regional relief for Groups I and II, i.e. parents, children and spouses. What it deliberately does not model: the state tariff band, the multiplier for kinship degree and the heir's prior wealth, business assets, several heirs with different shares, and the valuation of the property itself. That calculation belongs with a Spanish tax adviser, not on a website.
For the valuation, what now generally counts is the higher of the agreed value and the cadastral reference value (valor de referencia) — the same figure that sets the taxable base when buying. How that works on a purchase is under purchase costs and ITP by region.
Why the deadline matters more than the rate
The regional relief does not fall to anyone simply because it exists. It must be claimed within the filing deadline in the inheritance tax return. Miss the deadline and the claim becomes contentious — and an estate in a region whose rules would take the bill down to almost nothing suddenly faces the full tax.
In practice that means: the first call after a death involving a Spanish property goes not to the estate agent but to a tax adviser on the ground — in the region where the property sits. For heirs without Spanish residence, two further points come in: they need an NIE before anything can be filed or transferred, and the transfer of title in the land registry requires the completed tax return.
After the transfer, the property runs like any other owned by non-residents: annual IBI to the town hall and non-resident income tax via Modelo 210, whether it is let or not.
Liquidity for the tax — without selling the property
The most common reason an inherited Spanish property is sold shortly after a death is rarely lack of interest. It is lack of liquidity: the tax falls due before the property produces anything, and several heirs rarely share the same cash position. The alternative to selling is mortgaging the inherited property — a Spanish mortgage on an unencumbered home, whose proceeds cover the tax and the payout to co-heirs.
The age rule applies unchanged here: on a release loan too, with two borrowers, the younger borrower's age sets the term — the framework is under the age limit on Spanish mortgages. Anyone wanting to act ahead of the event finds the lifetime variant under releasing equity instead of gifting.
