Trust Taxation · Madrid · Alcobendas
Updated April 2025 · By International Inheritance Spain · Jacob Salama, Colegiado n.º 11.294
Spanish inheritance tax (ISD — Impuesto sobre Sucesiones y Donaciones) is administered by autonomous communities. A trust beneficiary who is a Spanish tax resident in Alcobendas falls under the ISD jurisdiction of Madrid. The regional ISD rules of Madrid apply to all trust distributions classified as a Spanish taxable event while the beneficiary is habitually resident in Alcobendas.
This is critically important: a trust beneficiary who lives in Alcobendas may pay dramatically different ISD from one who lives in Madrid or Andalucía, even if they receive exactly the same trust distribution.
The Spanish Tax Authority (AEAT) treats foreign trusts as fiscally transparent under doctrine confirmed in DGT binding consultations V1229-12, V2083-12, V3013-13, V1948-16 and V2375-18. Spain does not recognise the trust as a legal entity. Instead, AEAT attributes trust assets and distributions directly to the settlor or beneficiary.
For a beneficiary in Alcobendas: the trust's assets may be deemed their property for Modelo 720 purposes, and any distribution triggers ISD under Madrid's rules.
Reductions for Direct Relatives in Madrid
99% bonificación for Group I and II heirs — effective ISD near zero for direct relatives. One of the most fiscally attractive regions in Spain.
The Community of Madrid has maintained its near-complete ISD exemption for direct relatives for over two decades, making it the preferred region for international families establishing Spanish tax residency.
Near-zero effective rate for direct relatives (99% bonificación). Collateral relatives and non-relatives: national scale 7.65%–34%.
Filing deadline: 6 months from the date of the settlor's death (Art. 67, Ley 29/1987). A 6-month extension can be requested in the first 5 months.
99% bonificación also applies to donations to children and parents in Madrid. Donations to non-direct relatives: national scale.
Filing deadline: 30 days from the date the distribution is made or becomes available to the beneficiary.
As a Spanish tax resident in Alcobendas, you must declare foreign trust assets on Modelo 720 if the underlying assets (bank accounts, investments, real estate) exceed €50,000 per category. The declaration covers the previous calendar year and is due by 31 March. Since the ECJ ruling (C-788/19) and 2023 reform, the base penalty for non-compliance is €200 per item.
A UK discretionary trust receives a claim from a beneficiary who lives in Alcobendas. The trust has assets of £800,000. The settlor dies and the trust distributes €350,000 to the Alcobendas-based beneficiary (child of the settlor). AEAT classifies this as an inheritance.
The rules of Madrid apply: Near-zero effective rate for direct relatives (99% bonificación). Collateral relatives and non-relatives: national scale 7.65%–34%.
There is no UK-Spain ISD treaty. The beneficiary must file ISD in Madrid within 6 months of the settlor's death, and must also check their Modelo 720 position on the remaining trust assets.
Moving to Alcobendas as a trust beneficiary without a prior specialist legal opinion can expose you to unexpected ISD liabilities, Modelo 720 obligations and potentially significant sanctions. The specific rules applicable in Madrid, the trust's structure, and the settlor's nationality all interact in ways that are not obvious without expert advice.
