The Spanish tax system has no native concept of the Anglo-American trust. When a foreign trust forms part of a cross-border estate involving Spain — most commonly a US, UK or Channel Islands testamentary or revocable trust — Spanish ISD treats the trust by analogy, attributing assets and distributions to the parties (settlor, beneficiary) on the basis of the trust's substantive characteristics.
The DGT has issued substantial doctrine in 2023–2026 on trust scenarios involving Spanish residents as settlors, beneficiaries or both. This article explains the framework and links to representative rulings.
Trusts are the single most common point of friction between Anglo-American estate planning and Spanish tax law. Spain has no native trust concept; every cross-border trust scenario is therefore an exercise in analogy.
DGT classifies foreign trusts case-by-case. The starting principle: a trust is transparent for Spanish tax purposes — assets and income are attributed to the settlor (where the trust is revocable or otherwise leaves economic control with the settlor) or to the beneficiaries (where the trust is irrevocable and beneficiaries have vested rights). Where the trust is discretionary and beneficiaries have no fixed entitlement, the analysis is more nuanced.
For ISD purposes, the typical mappings are: (i) the contribution by a settlor to a revocable trust is generally a non-event (no transfer of economic ownership); (ii) the contribution to an irrevocable trust may be characterised as a gift to the beneficiaries or to the trustee, depending on the trust's terms; (iii) distributions from a revocable trust to a beneficiary may be characterised as gifts from the settlor to the beneficiary (if the settlor has economic control); (iv) distributions on the settlor's death from a testamentary trust are typically inheritances from the deceased to the beneficiaries.

📖 DGT doctrine in plain English for tax purposes in Spain
DGT applies the substance-over-form principle to trusts, classifying them by reference to revocability, discretionary character, and economic ownership. The trust is generally transparent for Spanish tax purposes, with assets and distributions attributed to the settlor or to the beneficiaries depending on the trust's structure. ISD applies to the underlying transfer (inheritance or gift) at the moment economic ownership passes; the trust's legal interposition does not shield the transfer from Spanish tax.

From our Spanish cross-border tax practice
Notes from real cases · International Inheritance Spain
The starting Spanish tax principle is transparency: the trust is generally treated as transparent, with assets and distributions attributed to the settlor or beneficiaries by reference to the trust's substantive structure. US revocable living trusts typically attribute to the settlor; UK discretionary trusts typically attribute to the beneficiaries. The Spanish tax events follow the attribution.
Common pitfall: Beneficiaries who receive distributions from foreign trusts often do not realise that Spanish ISD or IRPF may apply. The trustee makes the distribution; the beneficiary banks it; six months later the AEAT writes asking why no Modelo 650 or Modelo 100 was filed.
If your family includes Spanish-resident beneficiaries of foreign trusts, the trustee should give 60-90 days advance notice of any distribution, with details for Spanish tax reporting in Spain. Last-minute distributions create avoidable compliance failures.
