Trust Beneficiary in San Jose: Spanish Inheritance Tax and Legal Obligations

Published April 2025 · 10 min read · By International Inheritance Spain

If you are based in San Jose, California and you are a beneficiary — or settlor — of a trust that holds Spanish assets, or if you are inheriting from a trust that included Spanish property, you face a specific set of legal and tax obligations that most US attorneys are not equipped to advise on. Spanish law does not recognise trusts as legal entities, and the Spanish tax authority (AEAT) treats trust assets as if they were owned directly by the settlor or beneficiary.

This guide explains the specific obligations and risks for San Jose-based trust beneficiaries and what steps to take to protect yourself.

The Core Problem: Spain Looks Through Your Trust

The trust is a cornerstone of common law estate planning — but Spain is a civil law country that does not recognise the trust as a legal institution. Spain has not ratified the 1985 Hague Convention on the Recognition of Trusts. When AEAT encounters a trust structure, it applies a fiscal transparency doctrine:

• The trust is not a taxpayer in Spain
• Trust assets are attributed to the settlor (while alive and in control) or to the beneficiary (on distribution)
• The trustee's legal title is disregarded for Spanish tax purposes
• Distributions from the trust to Spanish-resident beneficiaries trigger Spanish Inheritance and Gift Tax (ISD)

This applies whether your trust is a UK family discretionary trust, a US Revocable Living Trust, an offshore trust from Jersey or the Cayman Islands, or any other common law trust structure.

Trust Structures and Spanish Assets: The San Jose Perspective

Whether you are a beneficiary of a family trust established in the UK, a US Revocable Living Trust with Spanish property, or an offshore trust (Jersey, Cayman Islands, Isle of Man) with Spanish connections, the Spanish tax analysis is the same: AEAT looks through the trust and attributes the assets and their tax consequences to either the settlor or the beneficiary.

For San Jose-based trust beneficiaries with Spanish connections, the key questions are:

• Have the trust assets been correctly declared on Modelo 720 (if you are or have been a Spanish tax resident)?
• When the trust distributes Spanish assets or assets of Spanish origin, what Spanish ISD liability arises?
• How does the Spanish inheritance tax interact with US federal and California estate and income tax?
• What FBAR, FATCA and Form 3520 obligations arise from the inherited Spanish accounts?

ISD: Spanish Inheritance and Gift Tax on Trust Distributions

When a trust makes a distribution to a beneficiary with Spanish connections, Spanish ISD applies:

• Distribution triggered by death (e.g., settlor dies, trust distributes to children): treated as an inheritance → ISD at succession rates, filed within 6 months of death
• Distribution during settlor's lifetime (e.g., discretionary payment to a beneficiary): treated as a donation → ISD at donation rates, filed within 30 working days

The tax varies significantly by the Spanish region where the assets are located. A distribution of €400,000 in Andalucía (Costa del Sol) attracts near-zero ISD for direct relatives. The same distribution in Cataluña could attract €40,000–€60,000 in Spanish ISD.

US Tax Obligations: FBAR, FATCA and Form 3520

As a US person (citizen or green card holder), you have additional IRS reporting obligations when inheriting foreign assets from a trust:

• Form 3520: Must be filed if you receive an inheritance or gift from a non-US person exceeding $100,000 in a year. Penalty for failure: up to 35% of the reportable amount.
• FBAR (FinCEN 114): Required if you acquire or inherit foreign financial accounts with aggregate value above $10,000 at any point in the year.
• FATCA (Form 8938): Required if specified foreign financial assets exceed the applicable threshold (from $50,000 for US residents).
• Foreign tax credit: Spanish ISD paid may potentially be credited against US tax — the mechanics require coordination between your US CPA and our firm.

California has no separate inheritance tax, but California residents who are trust beneficiaries receiving income from foreign trusts may have California income tax obligations on distributions. The California Franchise Tax Board (FTB) takes an expansive view of its jurisdiction over trust income — professional advice from a California tax attorney alongside our Spanish advice is recommended.

Granting a Power of Attorney from San Jose

If you need to deal with Spanish assets inherited through a trust structure, you can grant a power of attorney without travelling to Spain. From San Jose, you can:

• Sign before a CA notary public and obtain an apostille from the California Secretary of State — plus a sworn Spanish translation
• Sign at the Spanish Consulate nearest to San Jose: the San Francisco (nearest Spanish Consulate)

We prepare all documents in advance. Once you sign and return the power of attorney, we manage the entire Spanish process on your behalf.

The Six-Month Deadline: Critical for Trust Distributions on Death

If the trust distribution is triggered by the settlor's death, Spain's six-month ISD filing deadline runs from the date of death — not from the date the trust makes the actual distribution. For many discretionary trusts, this creates a timing problem: the trustee may take months to value, administer and distribute the estate, while the Spanish clock is already running.

Contact us immediately when a settlor with Spanish assets dies. We can file the ISD return on estimated values within the deadline and correct it once the trust distribution is finalised.
