The Basque Country has its own tax rules, separate from the rest of Spain.

  • Children, spouses, and parents benefit from a €400,000 allowance.
  • The rest of the inheritance is subject to progressive taxation, depending on the total value.
  • For gifts (donations), there are also important allowances for transfers between parents and children, especially if notarized.

Examples:

  • A son inheriting €350,000 → pays nothing, as it is below the €400,000 allowance.
  • A daughter inheriting €600,000 → only €200,000 is taxable (after the €400,000 allowance).

2. Making a Will in the Basque Country

  • Foreigners with assets in the Basque Country are strongly advised to make a Spanish will.
  • Under EU Regulation 650/2012, you can choose that your national law governs your inheritance.
  • A Spanish will avoids conflicts between heirs and speeds up the probate process.
  • Wills are signed before a notary and registered in the Central Registry of Wills.

3. Executing an Inheritance in the Basque Country (Probate Process)

The probate process generally includes:

  1. Obtain the death certificate.
  2. Request the last will certificate (Certificado de Últimas Voluntades).
  3. Gather a list of assets (real estate, bank accounts, investments, vehicles).
  4. Inheritance deed signed before a notary (escritura de aceptación de herencia).
  5. Inheritance tax filing within 6 months (extensions may be requested).
  6. Register inherited property at the Land Registry.

Typical timeframe: 3–6 months, depending on documentation and family agreements.
