Spanish inheritance tax has a bad reputation, but if you own property in Andalusia the picture in 2026 is far better than most people think. For close family members the regional allowances are extremely generous. For non-relatives and unregistered partners, the bill can still be heavy if you do not plan ahead.
This guide focuses on how inheritance tax actually works for property in Andalusia in 2026, with clear figures and worked examples.
This is general information, not legal or tax advice. For any real case you need a qualified adviser.
1. How Spanish inheritance tax works in practice
Spain charges Impuesto sobre Sucesiones y Donaciones (ISD) on inheritances and gifts. It is a personal tax, calculated separately for each heir, not a single tax on the estate as a whole.
In practice, the tax for each beneficiary is calculated based on several factors, including:
- The value of the assets inherited in Spain
- The heir’s relationship to the deceased
- The heir’s pre-existing wealth
- The Autonomous Community with taxing competence (for Andalusian property, this is usually Andalusia)
ISD operates under a state-and-regional system:
- State law sets the basic tax brackets and structure, with rates starting at around 7.65% and rising to 34%, before applying legally defined multipliers.
- Autonomous Communities then apply their own reductions, allowances, and bonificaciones. In Andalusia, these regional measures can reduce the final tax bill to a very low amount for close family members who meet the conditions.
In other words, the national rules provide the framework, and Andalusian law determines the final outcome in most real-world cases.
2. Relationship groups I–IV in Spanish inheritance law
Spanish inheritance tax law divides beneficiaries into four relationship groups, a structure that is also used by Andalusia.
Group I
Children and adopted children under 21 years of age.
Group II
Children and adopted children 21 or over,
Spouses,
Parents and other ascendants.
Group III
Siblings,
Uncles and aunts,
Nephews and nieces,
Ascendants and descendants by affinity (for example, parents-in-law or children-in-law).
Group IV
More distant relatives,
Unrelated persons.
At state level, the standard reductions in the taxable base are:
- €15,956.87 per heir for Groups I and II
- €7,993.46 per heir for Group III
- No reduction for Group IV
Andalusia applies much more generous regional reductions and tax credits for Groups I and II, which can significantly reduce or nearly eliminate inheritance tax for close family members who meet the conditions. These enhanced benefits do not generally extend to Group III or IV.
3. Andalusia’s special rules in 2026
Andalusia remains one of the most favourable regions in Spain for inheritance tax for close family. The key measures introduced for deaths from 1 January 2022 onwards are still in force in 2026.
3.1. Personal reductions by relationship
Groups I and II
A €1,000,000 reduction per heir on the taxable base applies for Groups I and II.
This covers children and adopted children, spouses, and parents/ascendants.
Group III
A €10,000 reduction per heir applies for Group III (for example, siblings, uncles/aunts, nephews/nieces, and certain relatives by affinity).
Group IV
Group IV does not benefit from these Andalusian reductions, and there is no state-level personal reduction for Group IV.
In addition, Andalusia applies a 99% bonificación on the tax due for Groups I and II in many cases, which can reduce the final tax payable significantly when conditions are met.
In practical terms, many standard family inheritances where each Group I or II heir receives up to €1,000,000 result in a very low tax bill in Andalusia, although the tax return must still be filed.
3.2. Main home: 99% reduction
Where the inheritance includes the deceased’s main residence, Andalusia provides a 99% reduction of the taxable base for that home in inheritances to:
- Heirs in Groups I and II, or
- A collateral relative over 65 who lived with the deceased for at least two years before death.
Key conditions include:
- The heir must generally keep the property for three years after death, with an exception if the heir dies within that period.
This home-related reduction is separate from the general personal reductions described above.
3.3. Disability reductions
Additional reductions may apply where the heir has an officially recognised disability. Professional summaries reflect improved reductions of:
- €250,000 where disability is at least 33% and under 65%
- €500,000 where disability is 65% or more
Eligibility and limits depend on the specific circumstances and applicable rules.
3.4. Family businesses and professional activities
Reliefs may apply to family businesses, professional activities and certain shareholdings, and can be very significant when the legal conditions and holding periods are met. This is specialist territory and should be reviewed with a tax adviser before restructuring or making will changes.
3.5. Registered partners (parejas de hecho)
Andalusia equates registered parejas de hecho to spouses for inheritance tax purposes where the couple is registered in the Andalusian Registry of De Facto Couples.
In practice:
- A properly registered partner is generally treated within the spouse-equivalent framework and can qualify for the Group I/II benefits.
- An unregistered partner is generally treated as a non-relative for inheritance tax purposes, which can materially increase the bill.
4. Tax rates: national brackets and Andalusian reality
Spain’s inheritance tax uses a progressive national scale, which continues to apply in 2026. Different portions of the taxable base are taxed at increasing marginal rates, in a structure similar to income tax.
At state level, the statutory rates range from 7.65% to 34%, before applying any multipliers. In very simplified terms, the national scale operates broadly along these lines:
- Lower slices of the base are taxed at around 7.65%
- Mid-range slices rise gradually through rates of roughly 10%–21%
- Higher slices move into the mid-20% range
- The highest portions of the base can reach up to 34%
After this base tax is calculated, a multiplier is applied depending on:
- the heir’s relationship group, and
- their pre-existing wealth.
For many Group I and II heirs with modest existing assets, this multiplier is often 1.0, meaning the base scale applies without increase.
In Andalusia, however, the practical impact of the national scale is often limited for close family. The combination of large personal reductions and the 99% bonificación frequently results in a very low or fully reduced taxable base, followed by a substantial discount on the remaining tax.
For Group III and Group IV heirs, the situation is different. Reductions are much smaller or non-existent, and the national scale together with the applicable multipliers plays a far more significant role in determining the final tax bill.
5. Worked examples
These examples are simplified and rounded. Real cases require proper valuation and professional advice, but they illustrate how Andalusian inheritance tax rules can work in 2026. These examples assume the deceased was habitually resident in Andalusia, so Andalusian ISD rules apply.
Example 1: Couple leaving a €300,000 main home to two adult children
Scenario
- The deceased’s habitual residence is in Andalusia.
- Main home in Andalusia valued at €300,000, no mortgage.
- On the second parent’s death, the home passes to two adult children equally.
Each child receives €150,000.
Simplified tax steps (per child)
- Base value: €150,000
- Habitual home reduction (99%) for Group I/II heirs (subject to conditions and holding period):
- 99% of €150,000 = €148,500 reduced
- Remaining base: €1,500
- Personal reduction for Group I/II in Andalusia (€1,000,000):
- Remaining base (€1,500) fully covered
Result (illustrative)
- Taxable base: €0
- Inheritance tax due: €0 (return still filed)
Other costs still apply: notary, Land Registry, and municipal procedures.
Example 2: Single owner leaving a €500,000 main home to an unmarried partner
Here, the legal status of the relationship is decisive.
Case A: Registered pareja de hecho in Andalusia
Scenario
- The partner is registered in the Andalusian registry and is treated in the spouse-equivalent framework for ISD.
- The property is the deceased’s habitual residence.
Steps
- Base value: €500,000
- Habitual home reduction 99% (if conditions are met): €495,000 reduced
- Remaining base: €5,000
- Personal reduction €1,000,000: remaining base absorbed
Result (illustrative)
- Taxable base: €0
- Inheritance tax: €0
The heir must file the return and comply with the holding period required for the habitual home reduction.
Case B: Partner not registered
Scenario
- The partner is not registered and is generally treated as a non-relative (Group IV) for ISD.
Steps
- Base value: €500,000
- No Andalusian personal reduction for Group IV
- No state personal reduction for Group IV (reduction is zero)
- National scale and applicable multipliers become central
Result (illustrative)
A five-figure inheritance tax bill is possible depending on the heir’s pre-existing wealth and the applicable multipliers.
Example 3: Non-relative inheriting a €250,000 holiday apartment
Scenario
- The property is a second home, not the deceased’s habitual residence.
- The beneficiary is a friend (Group IV).
Steps
- Base value: €250,000
- No habitual home reduction
- No Andalusian personal reduction for Group IV
- No state personal reduction for Group IV
Result (illustrative)
Inheritance tax can be substantial, as the national scale and multipliers apply.
Also, heirs must check local municipal taxes linked to the transfer. For Plusvalía (IIVTNU), the taxable event in an inheritance is tied to the date of death (the date of transfer), not to a later sale.
Which rules apply can change depending on the deceased’s habitual residence and the heir’s situation, especially in non-resident cases.
6. Deadlines and compliance in Andalusia
Even if the inheritance tax bill is zero, heirs must still follow the formal rules and deadlines.
Tax return deadline
Inheritance tax is normally filed within 6 months of the date of death.
A single 6-month extension can be requested, but it must be requested within the first 5 months.
Where to file
If Andalusia is the competent administration for the inheritance, the return is filed with the Agencia Tributaria de Andalucía (ATRIAN). In cross-border or non-resident situations, filing may instead fall under the state tax agency (AEAT), depending on the competence rules.
Other costs
- Notary and Land Registry fees
- Local municipal procedures and taxes linked to the transfer of the property, including Plusvalía Municipal (IIVTNU) where applicable, which is assessed in inheritances based on the transfer at the date of death
Missing deadlines can lead to surcharges and interest, even when the underlying regional allowances are generous.
7. FAQ: Inheritance tax in Andalusia 2026
Do children pay inheritance tax in Andalusia in 2026?
Children inheriting from parents often benefit from a €1,000,000 reduction per heir in Andalusia and, in many cases, a 99% bonificación on the tax due. This means many ordinary family inheritances result in a very low or nil inheritance tax bill, although the return still has to be filed.
What about spouses and registered partners?
Spouses and properly registered parejas de hecho in Andalusia are treated within the spouse-equivalent framework and can access the same Group II benefits, including the €1,000,000 reduction and 99% bonificación, provided conditions are met. Unregistered partners are generally treated as non-relatives and do not qualify for these benefits.
Is the main home always taxed at 1% or less?
No. Where the heir is in Group I or II, and the property qualifies as the deceased’s habitual residence with the required holding period, Andalusia provides a 99% reduction in the taxable base for that home. In many cases, the remaining base is then covered by the personal reductions. This habitual home reduction does not apply to non-relatives.
Do non-residents pay inheritance tax in Spain?
Yes. If you inherit property or other assets located in Spain, you can be liable for Spanish inheritance tax even if you live abroad. Which regional rules apply and where the return is filed depends on the competence rules for the case. EU/EEA non-residents can generally access the relevant regional tax benefits under the applicable framework, but the outcome should be confirmed with a specialist for cross-border estates.
8. Key takeaways for foreign property owners in Andalusia
For spouses, properly registered partners, children and parents, inheritance tax in Andalusia is often significantly reduced through the combination of the €1,000,000 per-heir reduction and the 99% bonificación, particularly where the inherited property qualifies as the deceased’s habitual residence and the conditions are met.
For siblings, more distant relatives and non-relatives, the situation is very different. Andalusian regional benefits are limited or unavailable, and the national inheritance tax scale and applicable multipliers play a much larger role in determining the final tax bill.
How ownership is structured, how your will is drafted, and the legal status of a partner can make a substantial difference. In some cases, proper registration or planning can move an heir from Group IV into Group II, which may be the difference between a manageable outcome and a situation where a sale of the property is required.
Deadlines and formal compliance still matter. Even where inheritance tax is low or nil, missing the six-month filing deadline or failing to submit the return can create unnecessary penalties and delays.
For foreign owners who want their heirs to preserve as much value as possible, the sensible approach is to have a Spanish will that fits into the wider estate plan and to obtain professional advice on how Andalusian inheritance rules apply to their specific circumstances.
