Inheritance tax by region in Spain
Quick answer
Inheritance tax is a state tax whose yield belongs to the regions, so reliefs and bonuses differ by region. The form instructions tie the rules to the deceased’s habitual residence, and the portal also mentions an option for the rules where the assets are. We print no relief because we could not verify them.
Applies toHeirs and families who want to understand why two estates are taxed differently. It does not compare regions.

§ 1One tax, many versions
The inheritance and gift tax is a state tax, and the revenue has been ceded to the regions. That cession lets the regions set their own reliefs, bonuses and in some cases rates, within the limits of the national framework. The result is a patchwork: a family can pay a small amount in one region and a large amount in another for the same estate. The chapter on the whole subject is inheritance and gift tax for buyers.
§ 2Which region applies
The tax agency's instructions for model 650 explain how the region is found. The relevant region is where the deceased had their habitual residence, which is the region in which the person spent the greater number of days in the five years before death. If that cannot be determined, the test is the region of the person's main centre of economic interests. The instructions do not give location of the property as the test. The official portal for non-residents adds that, for non-residents, the competence table generally places the competence with the State, and mentions an option to apply regional rules tied to the location of the assets. The two sources describe different situations, so the safe course is to ask an adviser which applies to your estate.
§ 3Navarre and the Basque Country
The official portal states that Navarre and the Basque Country apply their own rules, because they have their own tax systems. An estate connected to those territories should be handled by an adviser who knows them. We have not verified their rules, so we print none.
§ 4How to find the reliefs
Each region publishes its reliefs on the website of its tax agency. Look for the page on inheritance and gift tax, then for the table of reductions by relationship to the deceased, and the rules on the family home and on business interests. Check the date of the page and whether a recent change is pending. Print the page and keep it with the estate papers.
§ 5What to compare
When two regions are possible, compare the whole result, not one relief. The factors to compare are the reduction for the relationship, the treatment of the family home, the allowance for each heir, the rules for the insurance and the rate scale. Ask your adviser to calculate the tax under each option, and to confirm that the option is open to you.
§ 6Why timing matters
The deadlines run from the date of death, whatever the region. An inheritance return is due six months from that date, and an extension of the same length can be requested in the first five months. Choosing the region should not delay the work.
§ 7A note on mistakes
Estates are sometimes handled under the wrong region's rules and corrected later at a cost. Ask your adviser to note in writing the rule used and the reason, and to keep the evidence of the deceased's residence, such as tax returns and utility bills.

FAQRelated questions
Which region’s rules apply?
Mostly the region where the deceased lived, judged by the greater number of days across the five years before death. The portal also describes an option linked to where the assets sit. An adviser should confirm which route your estate takes.
Why do you not print the reliefs?
Regions change their reliefs often, and we could not trace them to an official source on the day of our check. A wrong figure could mislead you, so the figures come from the regional tax agency and the method comes first.
Does the Basque Country follow the same system?
No, those two territories run their own tax systems, as the portal notes. When the deceased or the property connects to either one, seek an adviser who knows their local rules.
