Spanish inheritance tax for non-residents is filed on Modelo 650, the self-assessed return that any heir living outside Spain must submit when they receive assets located here — a flat on the coast, a bank account, or a life insurance policy taken out with a Spanish insurer. The same form applies when the person who died was a non-resident, even if the heirs themselves live in Spain: it is the deceased’s residence, not the heir’s, that decides where the tax is filed. Unlike an heir who inherits from someone who lived in Spain and settles the tax with their own regional government, both the non-resident heir and anyone inheriting from a person who died abroad file with Spain’s central tax administration, on its own deadline and at its own office. This article explains when that six-month clock starts, how to request the extension, what happens with life insurance payouts, and which regional tax breaks apply to heirs living in New York, London or Dublin, as part of a broader international inheritance.
Modelo 650 must be filed, within six months of the death, by every non-resident heir who receives assets located in Spain. It is submitted to the National Tax Management Office (Oficina Nacional de Gestión Tributaria) and allows a single six-month extension, requested within the first five months, with late-payment interest accruing from month six.
Spanish Inheritance Tax Base for Non-Residents
Modelo 650 brings together everything that makes up the taxable estate: real estate, bank accounts, vehicles, company shares, and also life insurance payouts when the beneficiary is someone other than the policyholder, because Law 29/1987 treats them as just another transfer on death, under article 3.1.c. The tax authority adds a flat 3% on top for household goods unless a different value is proven, as set out in article 15 of the same law. Since Supreme Court Ruling 342/2020, of 10 March, that 3% no longer applies to cash, shares, or other assets that by their nature are not for personal use — which, in the estate of a non-resident, often just a flat and an account, brings the figure down considerably. Subtracting deductible debts and expenses — funeral costs, final illness, charges on the assets — and applying whatever reductions for kinship or disability apply, produces the net taxable base, the figure the tax is actually calculated on. Confusing the two is the most common mistake when filling out the form: the reduction comes off the taxable estate, not off the final result.
- Real estate and property rights located in Spain.
- Bank accounts, deposits and securities held with Spanish institutions.
- Life insurance payouts where the beneficiary is not the policyholder.
- The flat 3% household-goods charge on the rest of the estate.
Six-Month Deadline and How to Request an Extension
The deadline to file Modelo 650 is six months from the date of death, or from when a declaration of death becomes final if there is no body. That is set out in Order HAP/2488/2014, which also names the National Tax Management Office, in Madrid, as the filing point for anyone who does not live in Spain: Modelo 650, 651 and 655 are all handled there, regardless of which region the assets sit in. Miss the deadline without requesting an extension, and the tax authority applies increasing surcharges plus late-payment interest.
Steps to Request the Six-Month Extension
The Spanish Tax Agency allows a single extension, for another six months, if it is requested within the first five months after the death. Granting it does not freeze anything: interest starts accruing from day seven until the return is actually filed, so it buys time but is not free. For someone living in Chicago or Dublin who needs time to track down the deceased’s accounts, those extra six months can be the difference between filing calmly or in a rush.
- Gather the death certificate and the certificate of last wishes (certificado de últimas voluntades).
- Fill out the extension request with the deceased’s details, the heirs, and the approximate value of the assets.
- File it online with a digital certificate, electronic ID, or Cl@ve, or on paper if none of those are available.
- Keep the receipt: the new deadline counts from the end of the original one, not from the date of the request.
Filing the Inheritance Tax Return as a Non-Resident
Filling out Modelo 650 means transferring to its boxes the value of each asset, the deductible debts, and the reductions for kinship, age or disability, arriving at the net taxable base. The state’s progressive tax scale applies to that figure, producing the tax due, before the multiplying coefficients that raise the bill the more distant the relationship between heir and deceased.
A self-assessment is a return in which the taxpayer calculates their own tax bill, rather than waiting for the tax authority to work it out. In Spanish inheritance tax, that means any mistake in the taxable base or the reductions is paid for, or reclaimed later, by the heir — not by the tax authority.
Regional Tax Breaks for Any Non-Resident Heir
Until 2015, a non-resident could only apply the state scale, harsher than almost every regional one. The second additional provision of Law 29/1987 opened that door in 2015 to residents of the European Union and the European Economic Area, and Law 11/2021, of 9 July, extended it to any non-resident at all: the current wording simply refers to “non-resident taxpayers”, without naming a country. Someone inheriting from the United States — where it is worth bringing in local estate lawyers alongside Spanish counsel — has the same right to apply the rules of the region where the greatest value of the Spanish-based assets sits, or the region where the deceased lived, if they lived in Spain. When no asset at all is located in Spain, the rules of the region where each heir lives apply instead — the case of someone living in Spain who inherits from a relative who died abroad.
Credit for Overseas Inheritance Tax Already Paid
Anyone who inherits while living in Spain is taxed on worldwide assets — everything they receive, wherever it sits — so an inheritance that already paid tax abroad risks being taxed twice. Article 23 of Law 29/1987 prevents that with a credit for international double taxation: the Spanish tax bill is reduced by whichever is lower of these two amounts.
- What was actually paid abroad under a similar tax on that same inheritance.
- The result of applying Spain’s effective average rate to the assets or rights located abroad that were taxed there.
It is worth keeping the foreign payment receipt, with a certified translation and, where the country requires it, an apostille: that is what backs up the credit if the tax authority reviews the return. The credit is only available to those taxed on worldwide assets; a non-resident heir is taxed only on the assets located in Spain, so there is no foreign tax to credit against a bill that was never worldwide in the first place.
Form 650 Versus Form 652 in Spain
Form 652 exists to settle, separately from the rest of the estate, up to four life insurance payouts received on death — but only in the regions that have approved it as their own form. Order HAP/2488/2014, which governs filing for non-residents, does not include Form 652 among what the National Tax Management Office accepts: it only lists Forms 650, 651 and 655. In practice, that means an heir living outside Spain who receives a life insurance payout from the deceased does not file a separate form — they fold that amount into Modelo 650 itself, just like the rest of the estate. Confusing the two forms sends people looking for a procedure that, for anyone filing with the central tax authority, does not exist.
| Aspect | Form 650 | Form 652 |
|---|---|---|
| What it covers | The whole estate, including life insurance payouts | Only life insurance payouts, filed separately |
| Territory | The whole of Spain | Only regions that have approved it as their own form |
| Available to non-residents | Yes, through the National Tax Management Office | No — the payout is declared within Form 650 |
| Maximum policies covered | No limit | Up to four insurance contracts |
| Filing deadline | Six months from the death | Six months from the death |
| Who files | Each heir, for their share of the estate | Each policy beneficiary, separately |
Frequently Asked Questions About Spanish Inheritance Tax for Non-Residents
When does the six-month deadline for Form 650 start?
From the date of death, not from when the heir finds out or accepts the inheritance. If there is a court declaration of death instead of a medical certificate, the clock starts once that declaration becomes final. Living outside Spain does not extend the deadline: it runs the same for residents and non-residents.
What happens if I file Form 650 late?
The tax authority applies a surcharge that grows with every month of delay, plus late-payment interest if the six-month extension is also exceeded. Never filing at all is worse: it can end in a full audit with a penalty, instead of a simple surcharge for being late.
Does Form 652 apply to an heir living in the United States?
No. Form 652 only exists in some regions, for taxpayers under their jurisdiction. A non-resident heir, whether living in the United States or anywhere else, declares the life insurance payout within Form 650, through the National Tax Management Office.
Can I apply a region’s tax breaks as a non-resident?
Yes, regardless of where the heirs live or where the deceased died. Since Law 11/2021, the second additional provision of Law 29/1987 grants that right to “non-resident taxpayers” without exception: the rules applied are those of the region where the greatest value of the Spanish-based assets sits, or, if there is none, those of the region where the heir lives.
Do I need an NIE to file Form 650?
Yes. Without an NIE (foreigner’s tax identification number), no tax can be self-assessed in Spain, and applying for one from abroad, at a consulate, usually takes longer than gathering the rest of the paperwork. It is worth requesting one as soon as it is clear there are assets to inherit.
