An anonymised educational case study examining how Spain taxes a UK national who holds simultaneously a discretionary beneficial interest and a life tenancy in two trusts settled by the same settlor — producing two entirely different Spanish tax treatments for the same person.
Spain does not have trust law. That statement, bald and familiar to any practitioner in this field, contains within it a problem of extraordinary subtlety: when a UK national who holds beneficial interests in two trusts considers moving to Spain, the absence of a Spanish trust concept does not mean the trusts are ignored. It means the AEAT must characterise each beneficial interest through the lens of Spanish civil law — and the result of that characterisation depends entirely on the nature of the interest being examined.
This case study presents a scenario that is, in our experience, under-analysed in the literature and deeply counterintuitive to clients and their UK advisers. Ms. Harrison is simultaneously the discretionary beneficiary of one trust and the life tenant of another. Both trusts were settled by the same person. She is considering relocating to Spain. And yet her two beneficial interests will receive wholly different Spanish tax treatment — one largely dormant while the settlor is alive, the other immediately and comprehensively taxable from the first day of Spanish residency. Understanding why is the purpose of this article.
Ms. Harrison is a British national who has spent her entire working life in the United Kingdom. She is now considering a move to Spain — drawn by the climate, the lifestyle, and the relative cost of living. She has no existing connection to Spain: no property there, no prior residency, no Spanish income. Her asset base, as it stands, is substantially UK-centred.
Ms. Harrison: British national. Long-term UK tax resident. Employed in London. Contemplating relocation to Spain within the next 12–24 months. No prior Spanish residency.
Personal assets:
Falcon 1990 Settlement (Jersey-administered discretionary trust, settled 1990):
Falcon 1992 Settlement (Jersey-administered interest-in-possession trust, settled 1992):
The contrast between the two interests could not be more stark in English trust law terms, and — as we shall explain — the contrast is equally fundamental in Spanish tax law terms, even though Spain has no domestic trust concept at all.
Spain's civil law system does not recognise the common law trust. There is no equivalent concept in Spanish property or succession law. The AEAT and the Dirección General de Tributos (DGT) have, over decades of binding consultation practice, developed a doctrine of look-through and re-characterisation: when a Spanish tax resident holds a beneficial interest in a foreign trust, the AEAT asks what the economic substance of that interest most closely resembles under Spanish civil law, and taxes accordingly.
The starting point in the DGT's analysis — confirmed in a number of published binding consultations over the past two decades — is attribution. The DGT's general position is that trust assets should be attributed to the person who holds the true economic ownership. For a discretionary trust where the settlor retains economic significance, the default is to attribute assets to the settlor while the settlor is alive. For a beneficiary holding a fixed entitlement to income, the analysis is different: the income entitlement looks more like a property right that the beneficiary themselves holds.
This is why Ms. Harrison's two interests produce different outcomes. Her discretionary interest in the Falcon 1990 Settlement is not a right to anything: it is a mere expectation (mera expectativa) that trustees might one day exercise their discretion in her favour. Her life tenancy in the Falcon 1992 Settlement is an immediate property right: she is entitled to the income as it arises, automatically and without any exercise of trustee discretion. Spanish tax law treats those two situations as fundamentally different, because they are.
A discretionary beneficiary holds no vested right to trust income or capital. The trustees may pay them everything, something, or nothing. This position has been characterised in DGT guidance as a mera expectativa — a mere expectation or contingent hope, not a legal right capable of enforcement. For Spanish tax purposes, a mera expectativa is not an asset that the beneficiary owns, and therefore not an asset on which the beneficiary can be taxed currently.
The logical consequence of this analysis is that, while the settlor is alive, the DGT's general position attributes the trust assets to the settlor rather than to any discretionary beneficiary. The settlor was the one who established the trust, transferred the economic value into it, and retains — in the DGT's view — a latent economic relationship with the assets, even after formally excluding herself from benefit. This creates a structural tension: Mrs. Falcon is excluded from benefit, so she receives no income or capital. Yet the DGT's general approach would assign the economic ownership of the trust assets to her, and in principle attribute the trust's income to her for Spanish IRPF purposes — a result she does not achieve in practice because she is not a Spanish resident.
The key consequence for Ms. Harrison is this: while Mrs. Falcon is alive, the Falcon 1990 Settlement is largely fiscally invisible to Ms. Harrison for annual IRPF purposes. No income arising within the trust is attributed to her. The trust generates income each year; she pays no Spanish tax on it. She holds a beneficial interest; but it produces no current Spanish tax obligation on an arising basis.
The picture changes entirely when trustees exercise their discretion and make a distribution to Ms. Harrison. At that point, the DGT treats the distribution not as a payment of income attributable to the beneficiary, but as a gift from the settlor to the beneficiary — an act of liberalidad routed through the trust mechanism. The applicable tax is Impuesto sobre Sucesiones y Donaciones (ISD) — Spanish gift tax — at rates ranging from 7.65% on the first tranche to 34% on amounts above €797,555. Regional bonifications may apply depending on the autonomous community of Ms. Harrison's fiscal domicile in Spain.
This is a striking result: a cash distribution from a trust that Ms. Harrison has never previously been taxed on is treated as a taxable gift from an elderly UK woman she may barely know, subject to ISD at gift tax rates. It arises from the DGT's characterisation logic: if the assets belong to the settlor (for Spanish tax purposes), then a payment out of those assets to a third-party beneficiary is a gift from the settlor, not a return of the beneficiary's own income.
When Mrs. Falcon dies, the DGT's attribution of trust assets to the settlor during her lifetime terminates. At that moment, all discretionary beneficiaries — including Ms. Harrison — face an inheritance tax event. The trust assets that were attributed to Mrs. Falcon are now treated as passing on death to the beneficiaries. If Ms. Harrison is a Spanish tax resident at that point, she is potentially subject to Spanish ISD inheritance tax (IHT) on her proportionate share of the Falcon 1990 Settlement assets, based on the applicable DGT value at date of death and her degree of kinship with the settlor.
The question of whether Ms. Harrison must declare the Falcon 1990 Settlement on Modelo 720 is one of the most genuinely contested issues in this area of Spanish tax law. Modelo 720 requires Spanish tax residents to declare beneficial interests in foreign trusts where the value exceeds €50,000. The question is whether a discretionary beneficiary — holding only a mera expectativa — is a "real and effective beneficiary" for Modelo 720 purposes, or merely a potential beneficiary.
The conservative approach — and the approach we recommend to clients in doubt — is to declare. The argument that a discretionary beneficiary is not a "real and effective beneficiary" is legally supportable but has not been definitively confirmed by the DGT or the courts. The risk of non-declaration, if the AEAT subsequently takes the view that declaration was required, is a late-filing penalty. The risk of declaration where it was not strictly required is negligible. In the absence of authoritative guidance specifically addressing discretionary beneficiaries who have never received a distribution, prudence dictates disclosure.
Ms. Harrison's position in the Falcon 1992 Settlement is structurally and legally different from her position in the Falcon 1990 Settlement. As life tenant, she has an immediate, automatic, and absolute entitlement to all income generated by the trust assets as that income arises. She does not need the trustees to exercise any discretion. She does not need to make a request. The income is hers by right the moment it arises. This is an existing, vested, enforceable property right — not a mere expectation.
Under Spanish civil law, this type of interest most closely resembles one of two established property concepts: a renta vitalicia (life annuity) or a usufructo (usufruct). Neither concept maps perfectly onto the common law life tenancy, but both are more closely analogous than the discretionary interest in the Falcon 1990 Settlement. The DGT has not definitively resolved which characterisation applies in all cases, and the choice between them has material tax consequences.
If the Falcon 1992 Settlement income entitlement is characterised as a renta vitalicia, the income is taxable under the savings base of IRPF — the same base that applies to investment income generally — but at the rates applicable to life annuity income, which involves a percentage inclusion based on Ms. Harrison's age at the time the annuity was constituted. The establishment of the entitlement itself could, in principle, be characterised as a gift event (the creation of a right of economic value by the settlor in favour of Ms. Harrison) — though since this occurred before Ms. Harrison's Spanish residency, the Spanish connecting factors for ISD on that constitutive event would be absent, and the gift characterisation would not in practice generate a pre-arrival Spanish ISD liability.
For wealth tax purposes under this characterisation, the value of the life annuity would be capitalised using the legal interest rate, producing a notional capital value that is included in Ms. Harrison's Impuesto sobre el Patrimonio (NWT) base.
The alternative characterisation treats Ms. Harrison's income entitlement as a usufructo — the Spanish civil law concept of a right to the fruits (income and use) of property belonging to another (the bare owners, i.e. the remaindermen). Under this characterisation, the income flowing to Ms. Harrison is taxable as rendimientos del capital mobiliario — income from moveable capital — at savings rates: 19% on the first €6,000, 21% on €6,001–€50,000, 23% on €50,001–€200,000, 27% on €200,001–€300,000, and 28% above €300,000. UK taxes paid on the same income (under PAYE or self-assessment in the UK) would be creditable against the Spanish liability under the Spain–UK Double Taxation Convention.
For wealth tax purposes under the usufruct characterisation, the value of the usufruct is calculated by reference to the underlying asset value of the trust and Ms. Harrison's age, using the formula: 89 minus her age (to a minimum of 10%). This produces a percentage of the trust's asset value that is included in her NWT base each year.
In practice, in several published DGT binding consultations on similar interest-in-possession structures, the DGT has tended to apply the usufruct analysis as the closer analogy for situations where a beneficiary has an automatic income entitlement over a defined fund of assets — rather than a simple payment stream divorced from the underlying assets. The usufruct characterisation is analytically more coherent in a trust-law context, as it preserves the conceptual distinction between the income beneficiary (Ms. Harrison) and the capital beneficiaries (the remaindermen).
Unlike the discretionary interest in the Falcon 1990 Settlement, the life tenancy in the Falcon 1992 Settlement produces an immediate ongoing Spanish tax obligation from the first year of Ms. Harrison's Spanish residency. She does not need to receive a distribution. She does not need the trustees to exercise any discretion. The income arises automatically within the trust and, because she is entitled to it as it arises, she must report it in her Spanish IRPF return for the year in which it arose — whether or not she actually received it in cash.
This is a critical and frequently misunderstood point. The life tenant's IRPF obligation arises on an arising basis, not a receipts basis. If the trustees of the Falcon 1992 Settlement hold the income within the trust for a period before transmitting it to Ms. Harrison — something that is common in practice — she is nonetheless taxable on it in Spain in the year it arose.
The capital of the Falcon 1992 Settlement presents a further question that has been addressed in DGT guidance. The remaindermen — the persons entitled to the capital on Ms. Harrison's death — have a fixed, ascertainable entitlement to the trust capital. However, the trustees have discretion as to the timing of any distribution of capital (though not as to the ultimate capital beneficiaries). In several published DGT binding consultations, the DGT has considered the application of Article 24.3 of the Ley del ISD in analogous situations, under which the acquisition of a right whose effectiveness is suspended pending a condition or an exercise of discretion may defer the IHT event until the discretion is exercised. This argument — if accepted — would defer the IHT event on the capital of the Falcon 1992 Settlement until the trustees actually distribute capital to the remaindermen, rather than at Ms. Harrison's death.
The table below summarises the Spanish tax treatment of each of Ms. Harrison's two beneficial interests across the principal tax heads:
| Tax dimension | Falcon 1990 Settlement (discretionary) | Falcon 1992 Settlement (life tenant) |
|---|---|---|
| Nature of interest | Mera expectativa — no vested right; trustees have absolute discretion | Vested property right — immediate automatic entitlement to all income as it arises |
| Annual IRPF while settlor alive | No attribution to Ms. Harrison; assets attributed to settlor (Mrs. Falcon) for Spanish fiscal purposes | Income taxable annually in Ms. Harrison's IRPF return as it arises (usufruct: rendimientos del capital mobiliario; annuity: savings base) |
| Spanish tax on distributions received | ISD gift tax applies (7.65%–34%) — treated as gift from settlor | Income already taxed on arising basis; distributions of income not separately taxable (avoid double taxation); capital distributions separate analysis |
| ISD on settlor's death | IHT event for all discretionary beneficiaries — progressive IHT rates on attributed share | No new attribution event at settlor's death; Ms. Harrison already holds a recognised Spanish property right; capital IHT question deferred under Art. 24.3 LISD argument |
| Wealth tax (NWT) | No NWT inclusion for Ms. Harrison while settlor alive (assets attributed to settlor) | Value of life interest included in NWT base each year: usufruct methodology (asset value × age %) or capitalised annuity value |
| Modelo 720 | Legally contested; conservative approach: declare (potential beneficiary vs. real and effective beneficiary debate) | Declaration of the income entitlement value required under Obligation 2 (rights and entitlements over foreign assets exceeding €50,000) |
| UK DTC credit | UK tax on distributed amounts creditable if/when distributions made | UK income tax paid on same trust income creditable against Spanish IRPF liability |
The period before Ms. Harrison triggers Spanish tax residency — before she has spent 183 days in Spain in a calendar year — is the most valuable planning window. Once she becomes a Spanish tax resident, the tax obligations described above apply automatically and cannot be reversed. The following options warrant analysis in that pre-arrival period.
Once Ms. Harrison becomes a Spanish tax resident, the following annual compliance obligations apply. The complexity of managing these obligations in parallel should not be underestimated; they require co-ordination between Jersey trustees, UK advisers, and Spanish tax counsel each year.
Ms. Harrison's IRPF return must include, each year: (i) her UK salary (grossed up for UK PAYE deducted, with credit); (ii) income from her personal investment portfolio; (iii) income from the Falcon 1992 Settlement, on an arising basis, characterised as rendimientos del capital mobiliario under the usufruct approach. For the Falcon 1990 Settlement, no annual arising-basis attribution applies while Mrs. Falcon is alive; but any distribution received must be reported as an ISD gift event, not in IRPF.
The three blocks of Modelo 720 must be assessed each year:
As a Spanish tax resident, Ms. Harrison is subject to NWT on her worldwide assets above the applicable exempt threshold (currently €700,000 in most autonomous communities, with an additional €300,000 personal residence exemption). Her NWT base will include: the London flat (if retained); the personal investment portfolio; and the value of her life interest in the Falcon 1992 Settlement, calculated using the usufruct formula (asset value × (89 minus age)% — which for a person aged, say, 55, would be 34% of the trust’s capital value). The discretionary interest in the Falcon 1990 Settlement is not included in her NWT base while Mrs. Falcon is alive.
Any distribution from the Falcon 1990 Settlement while Ms. Harrison is a Spanish tax resident must be reported as a gift for ISD purposes. The ISD return (Modelo 651 for gifts) is due within 30 business days of the date of the gift. The applicable rate and regional bonifications depend on the autonomous community of Ms. Harrison’s fiscal domicile. Trustees should be briefed to provide advance notice of any intended distribution so that the ISD analysis can be completed before the distribution is made.

Advance analysis before you trigger Spanish residency is always more valuable than resolving problems after the fact.
