Inheritance tax in Spain: allowances and tax reductions

In Spain, inheritance tax falls within the competence of the Autonomous Communities. This system results in significant differences depending on the region concerned, both in terms of allowances and tax reductions.

Competence of the Autonomous Communities

Each Autonomous Community determines:

  • the applicable allowances,
  • the possible tax reductions,
  • the methods used to calculate the tax.

Applicable allowances

In many Autonomous Communities, a substantial allowance is granted for close heirs, in particular the surviving spouse and descendants.

Tax reductions

Certain regions apply significant tax reductions which may, in practice, lead to very limited or even symbolic taxation.

Regional illustration

In some Autonomous Communities, such as the Valencian Community, the combined effect of allowances and reductions explains why the effective tax burden is often low, even where substantial real estate assets are involved.
