If you have just inherited money in Spain, or you are about to inherit from a parent, the first shock is usually not the amount. It is discovering that the tax bill depends almost entirely on which Comunidad Autonoma you or the deceased lived in. Two heirs with identical inheritances, one in Madrid and one three hundred kilometres away, can end up paying wildly different sums under the same national tax.
The honest answer: Spain’s Impuesto de Sucesiones y Donaciones (ISD) is a national tax, but the regions set their own reliefs on top of it, ranging from near-total relief for close family in places like Madrid or Andalusia to considerably stricter treatment elsewhere. You cannot plan sensibly until you know which regional rules apply, and that usually depends on where the deceased was resident, not where you live.
For the practical side, see the XTB vs Trade Republic head-to-head.
I cover this in detail in the Coast FIRE calculator.
Once the tax question is settled, the investing decision is simpler than most people expect. Park the money, take your time, and build a diversified accumulating UCITS ETF portfolio rather than reacting emotionally to a sudden windfall. I will walk through both halves below, because doing the tax part wrong can cost you far more than any investing mistake.

Impuesto de Sucesiones is levied by the state, but almost all of the practical detail — allowances, reductions, and in several regions a near-complete bonificación (rebate) — is set by the seventeen Comunidades Autonomas. National guidance sits with the Agencia Tributaria, but the regional relief is administered by your Comunidad’s own tax office (Hacienda autonómica).
For the bigger picture, see our European ETF tax pillar.
Methodology: the calculations in this guide apply our tax calculation assumptions.
What determines which region’s rules apply is where the person who died was habitually resident, not where the heirs live. If several heirs are scattered across different regions but the deceased lived in one place, that place’s rules generally govern the calculation. This is the most misunderstood part of the process, and it is worth getting a local asesor fiscal to confirm before you file anything.
Kinship groups and allowances
Spain groups heirs into kinship classes (grupos), and the group you fall into changes both the base allowance and the multiplier applied to your bill. Children, spouses, and direct descendants sit in the more favourable groups; siblings, nieces, nephews and unrelated heirs see smaller allowances and higher effective rates. This structure is broadly consistent nationally, but whether a regional rebate applies on top of it varies enormously.
The near-99% relief regions versus the rest
Several regions, Madrid and Andalusia being the best known, apply a bonificación that can approach 99% of the tax due for spouses, children and parents (Group I and II heirs), meaning the ISD bill for close family is small or near zero regardless of estate size. Other Comunidades apply far more modest reductions, so the same inheritance can trigger a genuinely material tax bill elsewhere. Treat any percentage here as approximate and 2026-vintage — confirm the current figure for your region and kinship group before filing.
Filing deadlines and the practical process
You generally have six months from the date of death to file and pay ISD, though a further six-month extension can usually be requested if applied for within the first five months. Missing the window brings surcharges that grow the longer you wait, so even if probate or property valuations are still ongoing, talk to a gestor or asesor early.
If the estate includes property, expect a formal valuation requirement, and be prepared for the town hall’s cadastral value and the market value to diverge — a common source of disputes, so keep any professional valuation you commission on file.
The classic mistake: property-heavy estates
A large share of Spanish inheritances are dominated by a family home or second property rather than cash. The mistake I see most often is heirs feeling pressured to sell quickly to cover the ISD bill, accepting a below-market price under time pressure. If cash is tight, check whether the regional office allows deferred payment before assuming a fire sale is the only option.
Once the tax is settled: don’t rush the investing decision
After probate and ISD are dealt with, the money that lands in your account is not “found money” to be deployed instantly. It is capital that needs a plan. The single biggest behavioural mistake with any inheritance is treating the sudden lump sum as an emergency that must be resolved this week. It rarely is.
My approach with readers in this situation is always the same three steps. Park the cash somewhere safe and liquid while you think — a high-yield account or a short-dated instrument, not equities, not crypto, not a broker’s “recommended” structured product. Write down what the money is actually for: retirement top-up, a house deposit, your children’s future, or long-term growth capital. Only then decide the portfolio. I cover concrete parking options in where to park a large sum short-term in Europe — the mechanics are the same whether the money came from an inheritance, a business sale, or savings.
Building the ETF plan for what remains
For most Spanish residents, the sensible long-term core is a small number of diversified, accumulating UCITS ETFs — typically a global equity fund tracking something like the FTSE All-World or MSCI ACWI, through a broker that suits the Spanish regime. If you haven’t compared brokers on cost and tax-reporting quality, our broker comparison for Spanish investors is a reasonable start.
One Spain-specific wrinkle is worth flagging: the traspaso regime that lets Spanish investors switch between traditional mutual funds without triggering an immediate taxable event does not extend to ETFs. ETFs are taxed on sale like any other security, so the fund-switching loophole some Spanish fund investors rely on simply isn’t available if you hold ETFs directly. I cover exactly how this works, and why it still doesn’t make ETFs the wrong choice, in Spanish ETF tax and the traspaso question.
Lump sum or phased deployment?
The statistically-favoured approach for a diversified portfolio is to invest the lump sum in one go, since markets rise more often than they fall, so time out of the market is usually the bigger cost. That said, if the sum is large relative to your existing portfolio and investing it all at once would genuinely stop you sleeping, phasing it in over three to twelve months is a reasonable compromise at modest expected cost. I set out the numbers behind this trade-off in investing a lump sum near all-time highs, and you can test your own scenario with the lump sum vs. DCA calculator.
How Spain compares with other EU inheritance regimes
It helps to see Spain’s regional patchwork against a more centralised system. Germany applies inheritance tax nationally, with allowances that vary by kinship class but not by federal state the way Spain’s regions differ from each other.
| Feature | Spain (varies by Comunidad) | Germany (national bands) |
|---|---|---|
| Who sets the main relief | Regional government (Comunidad Autonoma) | National law, uniform across states |
| Close-family relief in favourable areas | Up to roughly 99% in some regions (Madrid, Andalusia) | Generous fixed allowance per child/spouse, then a tax band applies |
| Filing window | Roughly 6 months (extendable) | No fixed short deadline, but notification duty applies quickly |
| Fund-switching tax deferral (traspaso equivalent) | Available for mutual funds, not ETFs | Not applicable; ETFs taxed under standard German fund rules |
| Biggest planning variable | Which region’s rules apply | Kinship class and Vorabpauschale on ETF holdings |
If you are comparing notes with family or friends dealing with a German estate instead, I wrote a parallel piece on inheriting money in Germany and the ETF plan that covers the same ground for that system.
My verdict: what I’d actually do
Confirm the regional relief that applies to your case before anything else — this single fact changes the picture more than any investing decision will. Use a local asesor fiscal for the ISD filing; this is not a do-it-yourself area given the regional variation and the cost of a missed deadline or wrong kinship classification.
Once the tax is handled, park the net proceeds, decide what the money is actually for, then build a simple, low-cost, globally diversified accumulating ETF portfolio through a broker suited to Spanish residents. Don’t let the traspaso limitation push you into expensive actively-managed funds just to keep a tax-deferral option open — higher fees usually cost more than that option is worth to a buy-and-hold investor.
Frequently asked questions
Q: Do I pay Spanish inheritance tax based on where I live or where the deceased lived?
A: The Comunidad Autonoma rules that generally apply are tied to where the person who died was habitually resident, not where the heir lives. Cross-border cases add further complexity, so confirm your specific situation with a Spanish tax adviser before assuming which region’s relief applies.
Q: Is Spanish inheritance tax really close to zero in Madrid?
A: For close family members in Group I and II (children, spouses, parents), Madrid and a few other regions apply a bonificación that can bring the effective tax close to zero on top of the state calculation. Treat the exact percentage as approximate and confirm the current figure with the regional tax office, since these reliefs can change.
Q: How long do I have to file and pay Spanish inheritance tax?
A: The standard window is around six months from the date of death, with an extension of a further six months usually available if you apply within the first five months. Missing the deadline triggers surcharges that grow over time, so start the process early even if probate is still ongoing.
Q: Can I defer the traspaso tax break by holding ETFs instead of mutual funds in Spain?
A: No. The traspaso regime that lets Spanish fund investors switch between traditional mutual funds without an immediate tax event applies to mutual funds, not ETFs. ETFs are taxed as ordinary securities, with capital gains realised and reportable when you sell.
Q: Should I invest an inheritance as a lump sum or spread it out over time?
A: For a diversified portfolio, investing the full amount at once has historically outperformed phasing it in, simply because markets spend more time rising than falling. If the sum feels too large to invest in one go emotionally, spreading it over six to twelve months is a reasonable middle ground with only a small expected cost.
Q: What should I do with an inherited property I don’t want to keep?
A: Get an independent valuation before agreeing a sale price, and check whether your region allows deferred or instalment payment of the ISD bill so you are not forced into a rushed, below-market sale simply to cover the tax. Once the property is sold and any capital gains tax is settled, the proceeds can go into the same parked-cash-then-ETF-portfolio process as any other inherited cash.
