Modelo 720 Reporting Obligations for Trusts and Trust Assets

Modelo 720 — Spain's annual information return for overseas assets — was introduced by Law 7/2012 as an anti-fraud measure requiring Spanish tax residents to declare assets held abroad above specified thresholds. For individuals involved in foreign trusts, the question of who must report and what must be reported is anything but straightforward. Spain has no domestic trust law, and the official guidance on trusts in Modelo 720 is limited to a few lines in the AEAT's FAQ document. Understanding how those lines interact with the DGT's broader position on trust taxation — and with the post-ECJ penalty framework in force since 2022 — is essential for every Spanish tax resident connected to a trust.

Background: What is Modelo 720?

Modelo 720 (Declaración sobre bienes y derechos situados en el extranjero) is an annual informational tax return required under the Eighteenth Additional Provision of the General Tax Law (Ley 58/2003, LGT), as amended by Law 7/2012. It must be filed between 1 January and 31 March each year in respect of the previous calendar year. The return covers three distinct categories of overseas assets:

• Block 1 — Bank accounts: Current accounts, savings accounts, term deposits, and similar accounts held in financial institutions outside Spain.
• Block 2 — Securities, rights, insurance, and annuities: Shares, bonds, mutual fund units, life insurance policies, and annuity rights held outside Spain.
• Block 3 — Real estate: Immovable property situated outside Spain, whether owned directly or through a foreign entity.

The obligation to file arises when the total value of assets in any single category exceeds €50,000 on 31 December of the reference year. Once an initial declaration has been filed, a supplementary declaration is only required in subsequent years if the value of assets in that category has increased by more than €20,000 above the figure declared in the most recent filing.

Who Must Report Trust Assets on Modelo 720?

This is the central question, and the answer depends on applying the DGT's "look-through" doctrine to the trust structure. Because Spain treats the trustee's legal title as fiscally irrelevant, the obligation to report trust assets in Modelo 720 falls on whoever Spain regards as the economic owner of those assets.

The Settlor While Alive

Where a Spanish tax resident is the settlor of a foreign trust and is still alive, the DGT's position — consistently stated in binding consultations including early DGT rulings (2008–2010) and DGT criteria established by 2017 — is that the settlor is treated as the owner of the trust assets for all Spanish tax purposes. The corollary for Modelo 720 is direct: the settlor must report the trust assets in Modelo 720 as if they were their own personally held assets, categorised by type (bank accounts, securities, real estate) under the appropriate block.

This obligation applies regardless of whether the trust is revocable or irrevocable, and regardless of whether the settlor has been formally excluded as a beneficiary. The DGT's "disregard" of the trust's legal structure means that the settlor's formal legal position under the trust deed is irrelevant to Spanish tax obligations. From Spain's perspective, the assets simply never left the settlor's patrimonial sphere.

The Beneficiary After the Settlor's Death

Following the settlor's death, the DGT's framework shifts the attribution of trust assets from the settlor to the beneficiaries. Spanish resident beneficiaries are therefore expected to report the trust assets in their Modelo 720, with each beneficiary reporting their proportionate share of the trust fund according to their entitlement.

However, the AEAT's FAQ document (Question 52) introduces a critical qualification for beneficiaries: the obligation applies to "real and effective beneficiaries", not to "potential beneficiaries." This distinction is pivotal:

• A beneficiary of a fixed interest trust (also called interest in possession trust) holds a present, enforceable right to income as it arises — they are a real and effective beneficiary and must report.
• A beneficiary of a purely discretionary trust has no current right to any trust asset or income; the trustee may never exercise discretion in their favour — they are a mere potential beneficiary and, per the AEAT FAQ, need not report trust assets in Modelo 720.

In practice, the distinction between "real and effective" and "potential" is a matter of substance over form. A trust labelled as discretionary that distributes predictably to the same beneficiary every year may be treated as conferring real and effective rights by AEAT inspectors, even if the trust deed technically preserves trustee discretion.

Can Both Settlor and Beneficiary Be Required to Report?

Theoretically, if both the settlor and beneficiaries are Spanish tax residents simultaneously (for example, a family where parent is settlor and adult children are named fixed interest beneficiaries), a question arises about double reporting. The DGT position prioritises attribution to the settlor while alive; the beneficiaries would only be obligated to report after the settlor's death. However, this is an area of genuine uncertainty and professional advice should be sought in multi-party Spanish resident trust situations.

The Three Reporting Categories and How Trust Assets Fall Into Each

Trust assets are not reported as a single "trust" item in Modelo 720. They must be disaggregated by type and reported in the appropriate block, exactly as if the Spanish resident held the assets directly. This disaggregation can be complex when the trustee manages a diversified portfolio.

To complete the disaggregation correctly, the Spanish resident needs detailed information from the trustee. The trustee's annual accounts or a trust schedule should ideally set out: (a) each asset held, classified by type; (b) the value of each asset on 31 December; and (c) the trust's bank balances (average and closing). If the trustee does not provide this information voluntarily, the Spanish resident must request it — preferably in writing, creating a paper trail.

Value Thresholds in Detail: The €50,000 Rule and the €20,000 Update Rule

The initial filing threshold for Modelo 720 is €50,000 per category on 31 December of the reference year. The thresholds apply independently per block — so it is possible to be obligated to file for Block 2 (securities exceeding €50,000) but not for Block 1 or Block 3 if those categories are below the threshold.

For trust assets, applying the threshold requires determining what share of the trust fund is attributable to the Spanish resident. If the DGT's position requires the settlor to report the full trust fund as their own, the entire fund counts towards the threshold. If a beneficiary reports only their proportionate share (e.g. as one of three equal discretionary beneficiaries after the settlor's death), only one-third of the trust's assets in each category is counted.

The update threshold — requiring a new Modelo 720 filing in a subsequent year — is triggered when the value of assets in any previously reported category increases by more than €20,000 above the value shown in the last filed return. For trust assets that fluctuate in value with market conditions (investment portfolios, properties), this means the Spanish resident must track the value of the attributed trust assets each year and file a supplementary Modelo 720 whenever a category crosses the €20,000 increase threshold.

Penalties After ECJ Case C-788/19: The Post-2022 Regime

The original Modelo 720 penalty regime was notorious for its severity. Assets not declared — or declared incorrectly — could be reclassified as "unjustified patrimonial gains" and subjected to a 150% surcharge on the assessed tax, plus fixed penalties per item unreported. These consequences could exceed the value of the undeclared asset itself, and the infringement never prescribed — assets omitted from Modelo 720 could be assessed at any time, regardless of how long ago they were acquired.

On 27 January 2022, the Court of Justice of the European Union (ECJ), in Commission v. Kingdom of Spain (Case C-788/19), declared three aspects of this regime incompatible with EU free movement of capital rules:

1. The automatic reclassification of undeclared assets as unjustified gains, without regard to the statute of limitations on the underlying taxes;
2. The effective imprescriptibility of infractions related to Modelo 720;
3. The disproportionate level of penalties, which could exceed 150% of the asset value.

Spain responded with Law 5/2022 of 9 March 2022, which reformed the Modelo 720 regime as follows:

• The automatic "unjustified gain" reclassification was removed for assets whose acquisition would have been time-barred under the normal 4-year statute of limitations;
• The fixed penalty for late or incorrect filing was reduced to €100 per item or group of items relating to the same asset or right, with a minimum of €500 per return;
• Infringement prescription now follows normal tax law rules (4 years);
• The proportionality cap prevents penalties from exceeding 2% of the asset value in cases of late filing.

It is important to emphasise that the ECJ judgment and Law 5/2022 did not abolish Modelo 720. The filing obligation remains fully in force for all Spanish residents with overseas assets above the thresholds. What changed is the consequence of non-compliance, which is now proportionate rather than confiscatory — but it still exists and can still trigger broader tax investigations.

Modelo 721: Crypto Assets Held in Trust

From fiscal year 2023 onwards, a separate information return — Modelo 721 — applies to virtual assets (cryptocurrencies, tokens, NFTs, and similar digital assets) held abroad. Modelo 721 parallels Modelo 720 in structure: the obligation arises when the total value of foreign virtual assets exceeds €50,000 on 31 December, and annual updates are required when values increase by more than €20,000 above the previously declared amount.

For trusts that hold cryptocurrency or other virtual assets as part of their investment portfolio, the same attribution analysis applies: if the Spanish resident is treated as the owner of the trust's virtual assets (because they are the settlor, or because they are a fixed interest beneficiary), those virtual assets must be reported in Modelo 721 in addition to any other trust assets reported in Modelo 720.

There is an important interaction to note: virtual assets held in trust must be reported in Modelo 721, not in Block 2 of Modelo 720. If the trust holds both conventional financial assets and crypto, the conventional assets go into Modelo 720 Block 2, and the virtual assets go into Modelo 721 separately. Double-reporting the same virtual assets in both returns is an error that can complicate future compliance.

Practical Examples: What to Report and How

Coherence Between Declarations: A Key Compliance Principle

One of the most important practical rules in Spanish trust taxation is this: your position in Modelo 720 must be consistent with your positions in IRPF and Wealth Tax. If you report trust assets as your own in Modelo 720 (because you are following the DGT's attribution-to-settlor rule), you must also include those assets in your Wealth Tax return and declare the income generated by those assets in your IRPF. Reporting in Modelo 720 but not in IRPF — or vice versa — is one of the most common triggers for AEAT compliance checks.

Conversely, if you take the position that, as a pure discretionary beneficiary, you are not required to report trust assets in Modelo 720, you must also be consistent: you should not be declaring those same assets in Wealth Tax or income from them in IRPF, unless you have separately concluded that another legal basis requires you to do so.

Consistency also means applying the same position across years. If you declare trust assets in Modelo 720 in year one, you cannot simply stop declaring them in year two without a documented reason (e.g. the settlor died and assets were re-attributed, or the trust was dissolved). Unexplained gaps in Modelo 720 filings attract AEAT attention.

Voluntary Disclosure for Past Non-Filing

If you have been a Spanish tax resident and have not previously filed Modelo 720 for trust assets that arguably required reporting, voluntary disclosure remains the recommended course of action. Under the current (post-2022) penalty regime, the cost of voluntary late filing is €100 per item (minimum €500 per return) — far less onerous than under the old regime. Voluntary disclosure also mitigates the risk of tax fraud proceedings, which carry much heavier sanctions.

The voluntary disclosure strategy must also address the underlying taxes: if Modelo 720 non-filing was accompanied by non-declaration of trust income in IRPF or trust assets in Wealth Tax, those taxes must also be regularised. A comprehensive voluntary disclosure covering Modelo 720, IRPF, and Wealth Tax together — with interest on arrears — gives the best protection. A Spanish international tax adviser can prepare the necessary filings and manage the AEAT communication.
