Inheritance Tax in Catalonia: Tax Rates, Reductions and Reliefs

Who pays Inheritance Tax in Catalonia

The tax is paid by heirs and legatees when Catalan rules apply. In a domestic case, this is generally where Catalonia was the region in which the deceased spent the greatest number of days within the five-year period immediately preceding death. The tax is administered by the Catalan Tax Agency (ATC).

It is common for heirs living outside Catalonia to assume they pay tax in their region of residence. They do not: the rule looks at the deceased's residence, not the heir's. After the European case-law evolution, non-resident heirs may also apply Catalan rules when these are competent.

General tariff of the tax in Catalonia

Catalonia applies its own progressive tariff on the taxable base, with rates that increase by tranches. The exact tariff and the tranches are set by the regional rules in force at the date of accrual, and the official text published by the Generalitat should be consulted to know the figures applicable in each case.

After the progressive tariff, the multiplying coefficients based on pre-existing wealth and kinship group are applied to the resulting gross liability. Finally, the regional reliefs that fit the case are applied to the tax due.

Kinship reductions

The Catalan rules establish specific kinship reductions applied on the taxable base to obtain the net taxable base. These reductions have their own amounts for each group:

• Group I: descendants and adoptees under 21. Base reduction plus an additional amount per year under 21, with a maximum cap.
• Group II: descendants and adoptees aged 21 or over, spouses, ascendants and adoptive parents. Specific reduction with its own amount.
• Group III: collateral relatives of the second and third degree, ascendants and descendants by affinity. Lower reduction.
• Group IV: strangers and more distant relatives. No kinship reduction.

Specific amounts are published by the Catalan Tax Agency and should always be checked against the rules in force at the date of accrual.

Reduction for the deceased's primary residence

When the heir acquires the deceased's primary residence, a significant reduction can be applied to the property value, subject to:

• The heir must be spouse, ascendant, descendant or collateral relative over 65 who lived with the deceased for the two years prior to death.
• The property must have been the deceased's primary residence.
• The heir must keep the acquisition for a minimum period (generally five years) to retain the benefit.
• There are maximum caps on the value that can be reduced.

It is common for heirs to sell the inherited home before the maintenance period ends without realising they lose the reduction. Worth reviewing before any subsequent transfer.

Family business and shareholdings reduction

The acquisition of an individual business, professional practice or shareholdings in entities can give right to a substantial reduction, provided strict requirements are met regarding the entity's economic activity, the family ownership percentage and the maintenance of the acquisition for a set period.

The conditions are technical and should be reviewed in detail before filing. For more information on the state reductions that coexist with the Catalan ones in this matter, see our guide on state reliefs in Spanish Inheritance Tax, where we explain the scope of the 95% relief for family business.

Kinship relief (Groups I and II)

Catalonia applies different kinship relief rules depending on the group. A spouse or stable partner may apply a 99% relief. For the other taxpayers in Groups I and II, a weighted average percentage by taxable-base bands applies.

For Group I, the scale starts with a 99% marginal percentage on the first €100,000 and then decreases by bands. For Group II —which includes, among others, children aged 21 or over and ascendants— the current first band has a 60% marginal percentage, which also falls as the base increases. It is therefore inaccurate to say that every lower-value inheritance received by an adult child is relieved at close to 99%.

These percentages apply to the tax liability, and some taxpayer-elected reductions are incompatible with the general kinship relief. The relief remains compatible, among other cases, with the deceased's primary-residence reduction. The calculation should always use the table in force on the chargeable date.

Group III and IV particularities

For Group III heirs (siblings, uncles, nieces, ascendants and descendants by affinity), reductions are smaller and the general kinship relief does not apply with the same scope. The tax bill is notably higher than for direct heirs.

For Group IV (strangers and very distant relatives), there is no kinship reduction and the effective taxation is the highest of the regime. It is always worth reviewing the specific case to identify reductions for disability or other personal circumstances that may apply.

In practice we see that inheritances between siblings in Catalonia are one of the points where most surprises arise: the combination of smaller kinship reduction and absence of a general relief produces tax amounts that can be significant. In these cases, anticipating the calculation and reviewing the possible application of objective reductions (primary residence where prior cohabitation is met, family business, life insurance, disability) can adjust the outcome without sacrificing prudent compliance.

Deadlines and filing form

The general deadline is 6 months from the date of death, extendable by another 6 months if the extension request is filed within the first 5 months. Filing is made with the Catalan Tax Agency and inheritance cases use Forms 650 and 660, with electronic filing where applicable.

If the heir is outside Catalonia, see our guide on inheritance with a non-resident heir, where we explain how the applicable regulations are determined, the role of the NIE and the possibility to act through a representative.

Special cases: residents and non-residents in Catalonia

If the deceased was resident in Catalonia, Catalan rules apply regardless of where the heirs live. If the deceased was a non-resident but the main asset of the estate is in Catalonia, Catalan rules may also apply (subject to the general rules on competence between administrations).

For heirs living outside Spain, the possibility to apply Catalan regional rules instead of the state rules can make a very significant difference. In practice we see many non-resident heirs unaware of this possibility who file initially under the state rules and lose reliefs they were entitled to.

Common mistakes in Catalan inheritances

1. Applying the kinship relief at a flat 99% without checking the tiered system.
2. Selling the inherited primary residence before completing the maintenance period for the reduction.
3. Not correctly identifying situations assimilated to family relationship (stable couples, foster arrangements).
4. Applying the family business reduction without meeting the activity or ownership requirements.
5. Filing past the 6-month deadline without requesting an extension.
6. Confusing Catalan forms with the state Form 650 and filing in the wrong place.
