When a foreign trust makes a distribution to a beneficiary who is resident in Spain, Spanish Impuesto sobre Sucesiones y Donaciones (ISD) may apply. The AEAT does not accept that a trust distribution is simply a private financial transaction between the trustee and beneficiary — it treats the distribution as either an inheritance or a donation, depending on when and why it occurs.
This guide explains how Spanish ISD is applied to trust distributions, how the tax is calculated, and what steps can be taken to manage the exposure.
Spanish ISD covers both successions (inheritance) and donations (gifts). The classification of a trust distribution determines the applicable tax rules, rates and allowances:
Classification: Succession (sucesión)
Taxable event: Date of settlor's death
Filing deadline: 6 months from date of death
Allowances: Succession allowances by heir group (I–IV)
Applicable law: Law 29/1987 (Succession and Gift Tax)
Classification: Donation (donación)
Taxable event: Date of distribution / confirmation of right
Filing deadline: 30 working days from date of donation
Allowances: Donation allowances (generally lower)
Applicable law: Law 29/1987 (Succession and Gift Tax)
The taxable base is the net market value of the assets distributed at the date of the taxable event:
Spain's national ISD law provides allowances by relationship group. The relationship used is between the beneficiary and the settlor (not the trustee):
After deducting the allowance, the remaining taxable base is subject to graduated rates from 7.65% to 34% (succession) or 7.65% to 34% (donation — slightly different band structure). The resulting figure is then multiplied by a coefficient based on the beneficiary's pre-existing net wealth (ranging from 1.00 to 2.40).
Spain's 17 autonomous communities can apply additional reductions. This is the most significant variable for trust distributions to Spanish residents:
Facts: A UK discretionary trust distributes £500,000 to a daughter who lives in Marbella (Andalucía). The distribution is triggered by the settlor's (father's) death.
Spanish ISD calculation (succession — Andalucía):
If the daughter lives in Cataluña:
This example illustrates why the choice of Spanish region is critical for trust beneficiaries.
Facts: A US revocable living trust makes a €200,000 distribution to the settlor's son (35 years old) who lives in Madrid. The settlor is still alive.
Spanish ISD calculation (donation — Madrid):
When a trust distribution is classified as a succession, the six-month ISD filing deadline runs from the date of the settlor's death — not from the date the trust actually makes the distribution. This can catch beneficiaries off guard, particularly for discretionary trusts where the trustee may take months to process the distribution after the settlor's death.
If the trust takes longer than six months to make the distribution, the beneficiary may find themselves past the filing deadline before they have even received the assets. The extension provisions apply — a six-month extension can be requested within the first five months — and filing on estimated values (to be corrected later) is possible. Contact us immediately when the settlor dies if a trust distribution is anticipated.
In countries that levy inheritance or estate tax on trust assets (e.g., the UK, the US), there is a risk of double taxation with Spanish ISD on the same assets. The analysis depends on:
For UK trusts: no treaty. UK IHT on the trust assets (if applicable) and Spanish ISD on the distribution are separate liabilities. UK IHT paid does not reduce Spanish ISD.
For US trusts: no treaty. US federal estate tax (if applicable) and Spanish ISD are separate.
Careful co-ordination between your Spanish and home-country advisers is essential to understand the total tax cost.

Yes. The Spanish Tax Authority (AEAT) treats foreign trust distributions as either inheritances or donations for ISD purposes. If the beneficiary is a Spanish tax resident, ISD applies regardless of where the trust is located.
If the distribution follows the settlor's death, AEAT classifies it as an inheritance (sucesión). If it occurs during the settlor's lifetime, it is treated as a donation (donación), with a 30-working-day filing deadline.
The ISD rules of the autonomous community where the beneficiary is habitually resident apply. This is critically important: Andalucía and Madrid offer near-zero effective rates for direct relatives, while Cataluña and the Balearic Islands can result in significant tax.
For inheritance (post-death) distributions: 6 months from the settlor's date of death, extendable by 6 months. For donation (lifetime) distributions: 30 working days from the date of distribution.
