State reliefs of the Spanish Inheritance Tax: the common minimum

What state reliefs are and why they matter

Spanish Inheritance Tax reliefs are amounts that reduce the taxable base (not the tax due) before the tax rate is applied. They are set as a minimum by Spanish Law 29/1987 on Inheritance and Gift Tax. Autonomous Communities can improve on them with their own regional reliefs, but they cannot reduce them below the state minimum.

In practice, this means that any inheritance handled in Spanish territory benefits from at least the state reliefs. If the relevant region has improved regional reliefs, the taxpayer applies the more favourable version. But the common floor is the five state reliefs we cover below. It is worth noting that the specific amounts may be modified by the regulation in force, and that many regions apply significant improvements (see the comparison by region).

State kinship relief

The kinship relief applies according to the Group to which the heir belongs in relation to the deceased. The state groups are:

• Group I: descendants and adopted children under 21. Base relief plus an additional amount for each year under 21, with a general cap.
• Group II: descendants and adopted children aged 21 or over, spouses, ascendants and adoptive parents. Base relief.
• Group III: collateral relatives of the second and third degree (siblings, nephews/nieces, uncles/aunts), ascendants and descendants by affinity. Base relief lower than for Groups I and II.
• Group IV: collateral relatives of the fourth degree or more distant, and unrelated persons. No kinship relief.

It is common for regions to significantly improve these amounts for Groups I and II, to the point that in many regions the regional relief effectively replaces the state one because it is much more generous. In any case, the state relief is the floor: less can never be applied.

State primary residence relief

Inheriting the deceased's primary residence entitles you to a state relief of 95% on the value of the home, with a maximum cap per taxpayer. The requirements:

• Heir from Group I or II, or collateral relative over 65 who lived with the deceased for the two years before death.
• Holding period requirement (at state level, 10 years; many regions reduce this).
• Application on the value of the home, not on the rest of the estate.

It is common to see families sell the inherited home before completing the holding period and discover later that they lose the relief and must regularise their position. The holding rule is strict: if breached, the relief is lost and a complementary self-assessment with interest must be filed.

State family business relief (95%)

Inheriting an individual business, a professional activity or shares in qualifying entities can give rise to a state relief of 95% on the taxable base. It is one of the most relevant figures in business succession, as it allows the activity to continue without the tax forcing the sale or break-up of the business.

The basic requirements are:

• Existence of a genuine economic activity (not mere asset holding).
• Sufficient family ownership and exercise of management functions, with majority remuneration by some member of the family group.
• Holding requirement during the established period (at state level, 10 years).
• Applicability of the Wealth Tax exemption to those assets at the date of accrual.

In practice we see that the qualification as a "family business" is where most disputes concentrate. The tax inspectorate reviews in detail the reality of the economic activity, the family share, the management functions and the remuneration. Properly preparing the file is decisive.

State life insurance relief

Amounts received by the beneficiaries of a life insurance contract where the policyholder is a different person from the beneficiary are taxed under Inheritance Tax (not under personal income tax). State law provides a specific relief of a limited amount, applicable to heirs of Group I and II.

This relief operates on the amount received from the policy and is added to the kinship relief. It is worth reviewing policies in advance to identify who is the policyholder, who pays the premiums and who is the beneficiary, as the tax consequences may differ significantly. Some regions maintain their own improvements over the state life insurance relief.

State disability relief

Heirs with a recognised disability are entitled to an additional relief, the amount of which depends on the level of disability accredited:

• Disability of 33% or more (and less than 65%): base relief.
• Disability of 65% or more: significantly larger relief.

The disability relief is applied in addition to the kinship relief. That is, a child with a recognised 65% disability benefits both from the Group II relief and from the disability relief. It is worth noting that the accreditation is made through an official certificate in force on the accrual date of the tax.

How state reliefs combine with regional improvements

When a region has an improved regional relief for the same figure (for example, kinship or primary residence), the taxpayer applies the more favourable version. They do not stack: either the state relief or the regional relief applies. The usual case is that the regional relief, when it exists, is more beneficial.

The case of additional figures is different. Some regions create reliefs that do not exist at state level (for example, specific reliefs for agricultural holdings, for inheriting cultural heritage or for severe disability). These apply within their own scope without displacing the state ones. The comparison by region helps identify the improvements in force in each territory.

Order of application: taxable base, tax due, relief

To understand the real effect of reliefs, it helps to keep in mind the mechanics of the tax:

1. The taxable base is determined (value of the estate less deductible charges and debts).
2. The reductions (kinship, primary residence, family business, insurance, disability) are applied, producing the net taxable base.
3. The tax rate is applied to the net taxable base, producing the gross tax due.
4. The multiplier coefficient based on kinship and pre-existing wealth is applied, producing the tax payable.
5. The regional reliefs on the tax due (where they exist, such as the 99% relief in Madrid, Andalusia or the Valencian Community) are applied, producing the final amount to pay.

The difference between a reduction (on the base) and a relief (on the tax due) is important. Reductions are always applied before the tax rate; reliefs after. In regions with a 99% relief on the tax due, the reduction may have less impact in absolute terms — but it is still necessary to correctly compute the intermediate tax due.

Common mistakes

1. Confusing reduction and relief, miscomputing the order of application.
2. Applying the state relief when the regional one is more favourable.
3. Forgetting the holding period for primary residence or family business and selling early.
4. Failing to properly document the family business requirements.
5. Forgetting the life insurance relief when the deceased had policies in place.
6. Not providing the disability certificate in force on the accrual date.
