First the distinction: succession law is not inheritance tax
Succession law determines, among other things, who inherits, which share someone receives and how much freedom you have to deviate from that in a will. Inheritance tax concerns the fiscal consequences of that acquisition. Those are two different investigations.
Under European succession law, the law of the country where the deceased had their last habitual residence generally applies. In a will, the law of your own nationality can be chosen under conditions. The European regulation does not harmonise inheritance tax. Choosing Dutch or Belgian succession law therefore does not automatically undo Spanish tax. See the explanation on planning an international inheritance and the European succession portal.
For an owner this means that one question — “What happens to our house?” — needs at least two answers: a legal answer and a tax calculation.
One question, four investigations
Map the ownership before looking at a will
Who is on the purchase deed is a logical starting point. But that does not always complete the analysis. The matrimonial property regime, any cohabitation agreement and previous gifts can also be relevant.
Make an overview with the names of the owners, their shares, the purchase date, the financing and any special rights. Also note who uses the home and who pays the costs. Keep the purchase deed and recent ownership information from the register with that overview.
Suppose two partners each own half. When one partner dies, the investigation in principle concerns their share, not automatically the whole home. Whoever acquires that share can then influence the use of the whole property. A surviving partner who wants to keep living there can have different wishes from children who want to sell their share.
Do you need a Spanish will?
Not every foreign owner necessarily needs a separate Spanish will. It can be practical, depending on the existing documents, family relationships and the countries involved. The most important thing is coherence: a new will must not unintentionally revoke an earlier will or create contradictory provisions.
So show the adviser all existing wills. Ask explicitly which assets fall under which document, whether a choice of law is desirable and how the surviving partner is protected. Also discuss what happens in the event of simultaneous death, a blended family or a child dying earlier.
A will is not a one-off document that can disappear from view after the purchase. A move to Spain, marriage, divorce or a new family situation is a good moment to have the arrangement reviewed.

Which taxes and costs should you have calculated?
With a Spanish home, several items can come together. Think of inheritance or gift tax, notary and registration costs, legal guidance and possibly municipal tax on the increase in value of urban land. A gift can also have tax consequences for the giver. So do not only ask what the child pays, but what the transfer costs all parties together.
The competent tax authority and applicable regional rules depend on the circumstances. The Spanish tax authority has a separate overview for inheritance and gift tax for non-residents. The address of the property alone is not enough to state a definitive rate without further details.
Have at least three scenarios compared: keeping ownership until death, gifting everything now and possibly a transfer with certain rights reserved. For each scenario, also ask about the consequences in the Netherlands or Belgium. A treaty on income tax is not automatically the answer to questions about inheritance tax.
Why a tax reduction is not the same as a percentage of the home
In reports about Spanish property, tax reductions are often summarised in striking percentages. Those say little without explanation of the calculation, conditions and target group.
An exemption or reduction of the taxable base works differently from a discount on the calculated tax. Suppose, purely as an arithmetic example, that the calculated tax is €5,000 and an applicable scheme gives a 90% reduction on it. Then €500 remains. That does not mean someone pays 10% of the property value. This example does not describe any current regional scheme.
So have a calculation broken down: the value used, deductible items, exemptions, rate, corrections and any reduction. Also ask which documents and deadlines are needed to actually apply an advantage.
Gifting to children: look at tax and practice
A gift can fit into estate planning, but it also changes control. Whoever becomes owner gains a position in later decisions. Think of sale, renovation, financing and the division of costs.
Discuss in advance whether the parents want to keep using the home. May a child sell their share? What happens in the event of a divorce, death or financial problems of a child? And who decides when several children have different wishes?
A reserved usufruct can be relevant in certain situations, but it is not a standard solution you choose without a calculation. Have it explained which rights the usufructuary and the bare owner have, how costs are divided and which later tax consequences can arise.
A good arrangement matches the real family use. A holiday home all the children want to keep together requires different agreements from a home whose proceeds must be divided later.
What do you do when you inherit a home in Spain?
Start by gathering information before you sell the home, divide it or make promises. Find the title deed, mortgage details, wills and details of running costs. Also map the heirs and their identification documents.
Then have it established which declarations, translations and legalisations are needed. In a cross-border estate, a European Certificate of Succession can help to prove the position of heirs. The right document depends on the file; have that determined before ordering unnecessary documents.
Meanwhile, keep an overview of insurance, utilities, community fees and access to the home. Uncertainty about the inheritance does not make practical obligations disappear. Appoint one contact person within the family, without excluding other heirs from decisions.
Which deadlines matter?
For files handled by the Spanish national tax authority, the AEAT mentions a filing period of six months after death for an inheritance. A request for extension must be made within the first five months. For gifts, this authority mentions thirty working days. Always check which authority and scheme apply to your file; do not assume one universal deadline for all regional procedures. See the AEAT frequently asked questions.
Note deadlines at the start of the file. Waiting until all family members agree on a sale can endanger a tax deadline. Also ask whether an extension has consequences for interest or other costs.
