El Inheritance tax and donations (ISyD) is one of the longest-standing tax instruments in our legal system. Its origin dates back to the old "Tax on Real Estate Rights" of the 18th century, which taxed the transfer of real estate. Today, this tax applies to the acquisition of property and rights for three main reasons:

  1. Death cause: The acquisition of the The heritage or a legacy.
  2. Donations: The acquisition of assets during life by donation.
  3. Life insurances: The collection of amounts derived from life insurance.

The Duality of Regulation: State and Regional

The main characteristic and, at the same time, source of complexity regarding Inheritance Tax is its dual regulation. There are general regulations for the entire State, but each of the 17 Autonomous Communities has the power to regulate key aspects such as tax rates, reductions, and applicable bonuses.

In the vast majority of cases, regional regulations determine the final tax burden. This results in a very diverse tax landscape in which, for example, taxation can vary significantly depending on the deceased's place of residence.

Passive Subjects and Kinship Groups

La Inheritance and Gift Tax Law The Spanish Tax and Customs Service (LISyD) establishes the following kinship groups to determine the tax base and applicable tax breaks. As a general rule, the closer the relationship, the lower the tax burden.

  • Group I: Descendants and adopted children under 21 years of age.
  • Group II: Descendants and adopted children aged 21 or older, spouses, ascendants and adoptive parents
  • Group III: Second and third degree collaterals (siblings, uncles and nephews), ascendants and descendants by affinity.
  • Group IV: Fourth-degree collateral relatives (cousins), and other relatives or persons without kinship relationship.

The Impact of Autonomous Regulation

Regional regulations can be classified into three main groups, which illustrates the significant differences in taxation in Spain:

  1. Regulation similar to the state one: Some communities maintain regulations very similar to the general ones, which can result in a considerable tax burden.
  2. Very beneficial regulation: A second group applies very significant discounts, reaching a 99% tax discount or even eliminating it for spouses and direct descendants (Groups I and II), as is the case, for example, in the Community of Madrid.
  3. More burdensome regulation: A third group of autonomous communities applies regulations that are more harmful than those of the state, which increases tax burdens for taxpayers. A well-known example is the situation in Asturias, where this tax has traditionally been very high.

Key features of the tax

In summary, the Inheritance Tax is characterized by:

  • Dependency of the Autonomous Community: The amount to be paid varies drastically depending on the applicable regional regulations.
  • Personal tax: It is paid exclusively by individuals.
  • Progressiveness: The larger the inheritance received, the higher the tax rate applied.
  • Influence of pre-existing heritage: In many cases, the tax burden increases if the heir or legatee's assets are high.
