Spain does not recognise the trust as a domestic civil-law institution (the 1985 Hague Convention has not been ratified), which forces the Spanish tax authority and the courts to seek a functional characterisation case by case in order to integrate trust cash-flows into the PIT, Inheritance & Gift Tax and Wealth Tax of the Spanish-resident party.
The DGT (Spanish ruling office) draws different lines according to the nature of the trust. For revocable trusts, income and assets are attributed to the settlor as if they had never left their estate. For irrevocable discretionary trusts, the transfer to the beneficiary takes place at each effective distribution, triggering Inheritance & Gift Tax (gift inter vivos or succession). For irrevocable trusts with a fixed beneficiary, doctrine has shifted toward attributing income to the Spanish-resident beneficiary as movable-capital income, treating the vehicle as transparent.
Reporting is intense: positions must be reported on Form 720 if value exceeds €50,000, and Form 721 applies for crypto assets held in trust. Failure to report has consequences for limitation periods, tax claw-back and penalties — softened after CJEU C-788/19.
This section covers DGT rulings, TEAC decisions, Supreme Court case law and practical analyses of trust characterisation in cross-border situations with a Spanish connection.
