Pre-Entry Planning for UK Residents with Family Trusts Moving to Spain: A Case Study

Overview: The Case of Mr. Andrews

The scenario considered in this case study is not unusual among the class of high-net-worth individuals approaching Spain as a future place of residence. A British national — referred to throughout as Mr. Andrews — is currently domiciled and resident in Switzerland. He is married, under a separation of property regime, to a Spanish citizen who is also resident in Switzerland. Mr. Andrews has adult children from a prior marriage.

Over the decades, Mr. Andrews has established three UK family settlements, under which he is the settlor but not a beneficiary. He holds a diverse portfolio of assets: bankable assets in Switzerland, shares in a private operating company and a private investment fund, a loan receivable from a related company, and real estate in both Spain and Switzerland. He draws a salary from the private investment fund.

He is now considering relocating to Andalusia. His Spanish-citizen wife is comfortable returning to Spain and the couple has identified a property they intend to make their primary residence. The question he has brought to his advisers — simultaneously UK tax counsel and Spanish international tax lawyers — is a simple one in its formulation but complex in its answer: what needs to happen before he sets foot in Spain as a tax resident?

Why Pre-Entry Planning Matters: The Hard Deadline

The starting principle of Spanish pre-entry planning is both elegant and ruthless: once you become a Spanish tax resident, the game has changed entirely. Spanish Impuesto sobre la Renta de las Personas Físicas (IRPF) taxes worldwide income from the moment of residency. There is no retrospective charge — Spain taxes accrual from the date of residency onwards — but from that date, the full apparatus of Spanish personal taxation applies: progressive rates up to 47% on general income, savings rates of 19–28% on passive income, and the worldwide wealth tax base of Impuesto sobre el Patrimonio (IP).

The residency trigger under Article 9 Ley 35/2006, de 28 de noviembre, del Impuesto sobre la Renta de las Personas Físicas (LIRPF) is the 183-day rule: spending more than 183 days in Spain in a calendar year creates a rebuttable presumption of residency. But residency can also be established earlier through the habitual residence test — if Spain is where the individual's centre of vital interests lies — and through the family connection test, under which residency of a non-legally-separated spouse or minor children in Spain creates a presumption of the taxpayer's own residency.

For Mr. Andrews, the family connection test matters immediately: his Spanish-citizen wife may arrive in Spain before him, and if she establishes residency, Spain will presume his residency unless he demonstrates his habitual residence elsewhere. The planning window is therefore not merely "before 183 days" — it may be considerably shorter once the household begins its move.

The practical rule of thumb for international tax practitioners advising relocating clients is this: all restructuring should be complete before 1 January of the year of arrival, and certainly before the date on which Spanish residency is acquired. Restructuring a trust or crystallising a capital gain after Spanish residency is too late. The tax arises the moment the income accrues or the gain is realised as a Spanish resident.

Before any planning can begin, Mr. Andrews and his advisers must produce a comprehensive asset map — a document that identifies every asset, its current tax treatment as a non-resident, and its projected treatment once he becomes a Spanish resident. The contrast between the two columns is the planning opportunity.

Bankable Assets in Switzerland

Mr. Andrews holds cash deposits and a securities portfolio in Switzerland. Currently, as a non-resident, Spain has no claim on income from these assets unless they are Spanish-source (they are not). On becoming resident, the position reverses entirely. Interest income will constitute rendimientos del capital mobiliario under Article 25 LIRPF, taxed as savings income at rates of 19% (up to €6,000), 21% (€6,000–€50,000), 23% (€50,000–€200,000), 27% (€200,000–€300,000), and 28% above €300,000. Dividends received from the portfolio will follow the same savings income scale.

For a high-net-worth investor holding a sizeable Swiss portfolio, the interaction with the Convenio entre España y Suiza (Spain-Switzerland Double Tax Treaty, signed 1966, revised by the 2009 Protocol) is important. The treaty reduces Swiss withholding tax on dividends and interest; once Mr. Andrews is Spanish-resident, he will credit Swiss withholding against his Spanish savings income tax liability, but the net burden is Spanish rates, which are the higher of the two.

Shares in the Private Operating Company and Private Investment Fund

Mr. Andrews holds minority or significant stakes in two private vehicles: an operating company (referred to as the POC) and an investment fund (PIF). Neither is listed. On a future disposal of either holding, Spanish capital gains treatment will apply: the gain is calculated as the difference between the acquisition value and the sale price, and is taxed as savings income at the scale noted above — up to 28% on gains above €300,000.

The critical pre-entry planning point for these shares is that gains crystallised before Spanish residency are outside the Spanish tax net entirely. If Mr. Andrews is considering a sale of either holding in the medium term, completing that sale while still Swiss-resident eliminates Spanish capital gains tax on the accrued gain.

There is also an important consideration around the Spanish exit tax (Article 95 bis LIRPF), which applies when a Spanish resident leaves Spain with an unrealised gain in excess of €4 million or a holding above 25% worth more than €1 million in any single entity. But this provision bites on exit, not entry — it is a consideration for future planning once Spain is his home, not a pre-entry concern.

Loan Receivable from the POC

Mr. Andrews holds a loan receivable from the private operating company. Interest payable under that loan will, once he is Spanish-resident, constitute savings income under Article 25 LIRPF. The same savings income scale applies. If the loan carries a commercially reasonable interest rate, the income will be straightforward to compute. If it is a zero-coupon or below-market loan, AEAT may seek to impute interest at market rates under the related-party transfer pricing rules.

Spanish Real Estate Already Held

Mr. Andrews already owns real estate in Andalusia — presumably the property the couple intends to use as their primary residence after relocation. Currently, as a non-resident, this property is subject to Impuesto sobre la Renta de No Residentes (IRNR). Under the Spain-Switzerland treaty and the Real Decreto Legislativo 5/2004 (TRLIRNR), non-residents owning Spanish property for personal use pay IRNR at 19% (EU/EEA residents) or 24% (third-country residents) on an imputed income equal to either 1.1% or 2% of the cadastral value, depending on whether the cadastral value has been revised within the preceding ten years.

On becoming resident in Spain, the property transitions from IRNR to IRPF. The main-residence exemption applies (no imputed income is charged on the primary residence), but if the property is not the primary residence — or if the couple owns additional Spanish property — imputed rental income at the 2% cadastral value rule will apply, taxed at marginal rates under the general IRPF scale, potentially up to 47%.

Salary from the PIF

Mr. Andrews draws a salary from the private investment fund. Currently, as a Swiss-resident, this is a matter for Swiss income tax (subject to the treaty allocation rules, which depend on whether the fund has a permanent establishment in Spain or the services are performed in Spain). On becoming Spanish-resident, this salary becomes rendimientos del trabajo under Article 17 LIRPF and is taxed at the general progressive scale — up to 47% on income above €300,000. There is no savings income treatment: employment income is always general income.

This is the asset with the largest immediate tax consequence of Spanish residency. A salary taxed at 47% marginal rate versus the Swiss rate creates a stark differential that makes the Beckham Law (discussed below) the single most valuable planning tool available.

The three UK family settlements are the most technically complex element of Mr. Andrews' pre-entry planning. Spain does not recognise the trust as a legal institution — there is no Spanish domestic law concept of a trust, and the Dirección General de Tributos (DGT) has developed a body of administrative criteria, through binding consultations, for determining how trust income and assets are attributed for Spanish tax purposes.

The central question is always the same: to whom should the economic reality of the trust be attributed? The DGT's approach looks at the degree of control the settlor retains, whether the settlor is a beneficiary, and the nature of the beneficiaries' rights.

The 1976 Settlement — Discretionary, Settlor Not a Beneficiary

The 1976 Settlement is a discretionary settlement established almost fifty years ago. Mr. Andrews is the settlor but is expressly and irrevocably excluded from benefit. The beneficiaries are his children from his prior marriage, none of whom (let us assume for this analysis) are currently Spanish tax residents.

Under the DGT's analytical framework, as articulated in consultations published over recent years, a discretionary trust in which the settlor is irrevocably excluded from benefit, retains no power to revoke or amend the trust, and has no control over distributions is treated as a separate entity whose income is not attributed to the settlor. The settlor has gifted the assets away — they are no longer his — and Spanish tax law should follow the economic substance.

On this analysis, provided Mr. Andrews genuinely has no power of revocation, no ability to add or remove beneficiaries, no reserved power to change the trustees without consent, and no letter of wishes that functions as a binding instruction, the 1976 Settlement should not generate Spanish IRPF in his hands. The trust income accumulates or is distributed to the children; since the children are non-Spanish residents, no Spanish tax arises on that income.

The pre-entry review of the 1976 Settlement trust deed should therefore focus on: (i) identifying every reserved or delegated power Mr. Andrews holds; (ii) assessing whether any protector or investment committee role he occupies constitutes "control"; and (iii) if necessary, taking steps — well before Spanish residency — to resign from any protector role or relinquish any power that could support an attribution argument.

The 1997 Settlement — Discretionary, Settlor Not a Beneficiary

The 1997 Settlement is substantively similar to the 1976 Settlement: Mr. Andrews is the settlor, is excluded from benefit, and the beneficiaries are his descendants generally (a class that will include grandchildren and potentially great-grandchildren). The same analytical framework applies.

One feature of this settlement that may assist the planning analysis is the width of the beneficial class. Because the beneficiaries are a wide class of descendants — many of whom may not yet exist — no individual beneficiary has a vested or identifiable interest in any specific portion of the trust fund. The DGT's criteria suggest that where no beneficiary has a defined entitlement, the income accumulates within the trust; it is only on distribution that the question of attribution to a specific beneficiary arises. While the trust remains undistributed, the income sits in an offshore vehicle that, on the present analysis, is not attributed to Mr. Andrews.

The same retained-power analysis applies. Additionally, if any of Mr. Andrews' children or grandchildren become Spanish residents in the future, they will need to consider their own Modelo 720 and IRPF obligations in respect of distributions they receive — but that is a planning question for them, not for Mr. Andrews personally.

The 1999 Grandchildren's Settlement — Interest in Possession

The 1999 Grandchildren's Settlement is structurally different from the other two and requires a distinct analysis. Under this settlement, two named grandchildren of Mr. Andrews hold interests in possession — they have an immediate, vested right to the income of the trust as it arises, following the end of an accumulation period that has already expired. The remaindermen (other descendants) will receive the capital on the termination of the life interests.

Under English law, the two life-tenant grandchildren have an enforceable right to receive trust income. They can compel the trustees to pay it. They cannot touch the capital, but the income is theirs as of right.

The DGT treats fixed interests in possession differently from discretionary interests. Where a beneficiary has a vested, enforceable right to the trust income, Spanish tax law looks through the trust and treats the income as arising directly to that beneficiary. This is a direct application of the DGT's economic substance approach: if the beneficiary effectively owns the income stream, Spain will tax them on it as though the trust did not interpose itself.

The implications are significant. If either of the two life-tenant grandchildren becomes a Spanish tax resident — or if they are already Spanish residents — they will be taxable under IRPF on their proportionate share of the trust income as it arises, regardless of whether it is actually distributed to them. They will also have Modelo 720 reporting obligations in respect of their interest in the trust assets.

For Mr. Andrews himself, the position is the same as under the other two settlements: he is not a beneficiary, so the income is not attributed to him. The planning focus for this settlement is therefore on the two life-tenant grandchildren, not on Mr. Andrews — though he should be aware of the issue as part of the broader family tax planning exercise.

With the asset map and trust analysis complete, the focus shifts to planning. There are four primary options available to Mr. Andrews before he acquires Spanish residency. In practice, the optimal plan will combine elements of several of these options, calibrated to the specific terms of each trust, the intended timing of the move, and the likelihood of qualifying for the Beckham Law.

Option A — Distribution Before Arrival

If the trustees of any of the three settlements are willing to make capital distributions to beneficiaries before Mr. Andrews becomes Spanish-resident, those distributions will fall outside the Spanish tax net entirely. Spain taxes on accrual from the residency date — it cannot reach back to distributions made while Mr. Andrews was a Swiss resident.

For Mr. Andrews himself, this option is irrelevant: he is not a beneficiary of any settlement, so he cannot receive a distribution. But for family members who are beneficiaries — children, grandchildren — a pre-arrival distribution from the trusts may represent a tax-efficient extraction of capital, provided the UK tax consequences (capital gains tax on gains accrued within the trust, inheritance tax considerations) are manageable. This requires close coordination between UK and Spanish advisers.

The timing discipline is strict: distributions must be received before Spanish residency is acquired. A distribution paid the day after Mr. Andrews' family moves into the Andalusian property — even if the money was resolved upon earlier — may be treated as arising in the first year of residency if the DGT takes the view that receipt (rather than resolution) is the relevant date.

Option B — Trust Protector Restructuring

If Mr. Andrews currently holds a protector role under any of the three settlements — a role that gives him power to direct or veto trustee decisions, remove and replace trustees, or consent to distributions — he should consider resigning from that role before becoming Spanish-resident. The reason is straightforward: the DGT's attribution analysis focuses on control, and a protector with substantive powers is a person who exercises control over the trust.

Resigning from a protector role before arrival in Spain removes this attribution risk prospectively. The resignation must be genuine and complete: Mr. Andrews cannot retain informal influence over the new protector or continue to receive information that is exclusively available to the protector role. If he does, AEAT may argue that the resignation was purely formal and that de facto control remains.

The timing of the resignation is important. It should occur well before Spanish residency — ideally in the calendar year before arrival — to establish a clear factual break between his former role and his new status as Spanish resident. A resignation executed two weeks before acquiring residency will face closer scrutiny than one completed twelve months earlier.

Option C — The Beckham Law Window

The most powerful planning tool available to Mr. Andrews is potentially the régimen especial de tributación de impatriados under Article 93 LIRPF — universally known as the Beckham Law. Under this regime, a qualifying individual who becomes Spanish-resident by reason of employment or specified activities is taxed as a non-resident for up to six fiscal years. The core advantage is that foreign-source income is not subject to Spanish IRPF during the Beckham period: only Spanish-source income is taxable.

For Mr. Andrews, the consequence of qualifying for the Beckham Law is transformative:

• His salary from the PIF: if paid by a foreign entity, it is foreign-source income and escapes Spanish IRPF during the Beckham period. If the PIF is restructured so that his employment role is with a Spanish entity, this advantage disappears — but an employment with a foreign parent and a secondment to Spain could preserve it.
• His Swiss bankable assets: interest and dividends are foreign-source. Under the Beckham regime, they are not subject to Spanish IRPF.
• Trust distributions: any distribution received from any of the three settlements during the Beckham period from offshore trustees is foreign-source income and would not be taxable in Spain during the regime's term.
• Gains on shares in the POC or PIF: if these are foreign-sited assets, the capital gains are foreign-source and outside the Beckham net.

The Beckham Law application window is tight: Mr. Andrews must apply using Modelo 149 within six months of the date on which he commences the qualifying employment or economic activity in Spain. Missing this deadline extinguishes the right to the regime for that period of residency.

The Beckham Law window is available once in a lifetime: once you have been Spanish-resident and applied under the regime, you cannot re-qualify on a later return to Spain. If Mr. Andrews misses the window, it is gone permanently.

Option D — Timing Capital Events Before Arrival

The fourth option is the most operationally straightforward but requires the fastest execution: completing any planned capital events — sales of shares in the POC or PIF, disposals of Swiss real estate, crystallisation of accrued gains in the securities portfolio — before Spanish residency is acquired.

A gain crystallised while Mr. Andrews is a Swiss resident is a Swiss tax matter (or potentially a UK tax matter, depending on the nature of the asset and his domicile status). It is not a Spanish tax matter at all. The Spanish tax system cannot reach gains that accrued and were realised before Spain had any claim on his income.

This option is particularly relevant if a sale of the POC or PIF was already under negotiation or being planned. The difference in tax treatment between a completion date before Spanish residency and a completion date after it could be the difference between zero Spanish tax and 28% Spanish capital gains tax on potentially very large amounts. The incentive to structure the timing correctly is overwhelming.

The Andalusian property that Mr. Andrews and his wife intend to use as their primary residence is already subject to Spanish IRNR. On becoming Spanish-resident, its treatment changes completely: from IRNR (non-resident imputed income tax) to IRPF, with the primary residence exemption eliminating the imputed income charge on the property actually used as the main home.

But the pre-entry analysis cannot stop there. Mr. Andrews should consider the following questions well before arrival:

Personal Name vs. Corporate Holding

Whether to hold the Spanish property in his personal name or through a Spanish Sociedad Limitada (S.L.) is a question with no universal answer. A corporate structure offers certain estate planning advantages and may, in specific circumstances, reduce transfer costs. But it also introduces the Impuesto sobre Sociedades (IS) at 25% on the company's deemed rental income (even for personal use), the anti-avoidance rules on sociedades patrimoniales (property-holding companies), the Impuesto sobre el Incremento del Valor de los Terrenos de Naturaleza Urbana (IIVTNU, the municipal capital gains tax) on future disposal, and the double layer of tax when profits are eventually extracted as dividends.

For a property used primarily as a personal residence, a Spanish S.L. structure is rarely efficient from a pure tax perspective. The S.L. does not benefit from the primary residence exemption on capital gains (which is available to individuals under Article 38 LIRPF), does not benefit from the Andalusian inheritance tax bonuses (which apply to direct-line heirs), and creates a compliance burden with annual IS filings, transfer pricing documentation if the shareholder occupies the property at below-market rent, and increased professional fees.

If the property is already held personally — as is typically the case — transferring it into an S.L. pre-arrival would trigger Impuesto sobre Transmisiones Patrimoniales (ITP) at Andalusian rates (currently 7%) and potentially Spanish capital gains tax on the accumulated gain (if the transfer is treated as a taxable disposal, which it typically is). The economics rarely justify the restructuring cost.

Additional Spanish Properties

If Mr. Andrews holds any Spanish property other than his intended primary residence, the post-residency position is different. A second property in Spain generates imputed rental income under Article 85 LIRPF (1.1% or 2% of cadastral value, depending on the revision date) taxed at the full general IRPF scale — potentially 47% at the margin. If the property is actually rented, the actual rental income is taxable at general rates (with a 60% reduction available on residential leases under Article 23.2 LIRPF, a significant relief). This comparison — imputed vs. actual rental income — should be part of the pre-entry planning review.

The Modelo 720 — the annual declaration of assets and rights held abroad — is one of the most important immediate compliance obligations for a newly arrived Spanish resident with a complex international asset base. Despite the 2022 ruling by the Court of Justice of the European Union (C-788/19) that certain aspects of the original penalty regime were incompatible with EU law, and the subsequent legislative modification of those penalties, the obligation to file the declaration itself remains fully in force.

Mr. Andrews must file Modelo 720 by 31 March of the year after the year in which he first becomes Spanish-resident. If he acquires residency on any date in the 2025 calendar year, his first Modelo 720 is due by 31 March 2026.

The Three Blocks of Foreign Assets

Modelo 720 covers three categories of foreign assets:

1. Block 1 — Foreign accounts: bank accounts held abroad in which Mr. Andrews is a holder, authorised signatory, or beneficiary, with a balance (or average balance in the last quarter of the year) exceeding €50,000 per entity. His Swiss bank accounts will almost certainly trigger this obligation.
2. Block 2 — Foreign securities, insurance, and savings: shares, bonds, investment fund units, life insurance policies and temporary income plans abroad with an aggregate value above €50,000. His interests in the POC and PIF (if not through a trust) and his Swiss securities portfolio will fall here.
3. Block 3 — Foreign real estate: real property situated abroad (Switzerland) with an acquisition value above €50,000. His Swiss real estate will trigger this obligation.

Trust Assets on Modelo 720

The trust question on Modelo 720 is technically the most difficult. Under Orden HAP/72/2013 and subsequent DGT guidance, the obligation to declare trust assets depends on the attribution analysis discussed in Step 2 above. If the DGT would attribute the trust assets to Mr. Andrews (because he retains control), he must declare them. If the trusts are correctly characterised as separate entities whose assets are not attributed to him, he has no obligation to declare them.

On the analysis set out above — assuming Mr. Andrews has been fully excluded from benefit and holds no retained powers — the three settlements should not require Modelo 720 reporting in his hands. But the analysis is fact-dependent: the trust deeds must be reviewed against these criteria, and where any doubt exists, conservative filing is preferable to non-filing.

For the two life-tenant grandchildren under the 1999 Settlement, if they become Spanish residents, they will have their own Modelo 720 obligations in respect of their interest in possession. The trust's underlying assets — to the extent of their life-tenancy share — are treated as their foreign assets for reporting purposes.

Mr. Andrews' relocation to Spain as a Spanish-resident raises inheritance planning questions that are entirely distinct from the income tax issues. Two bodies of law interact here: succession law (which governs what happens to his estate) and the Spanish Impuesto sobre Sucesiones y Donaciones (ISD), which governs how that inheritance is taxed.

Succession Law: EU Regulation 650/2012 and the Election of Applicable Law

EU Regulation No. 650/2012 on matters of succession (the Succession Regulation) applies across EU member states (excluding Denmark) and provides that the law applicable to succession is, by default, the law of the country of habitual residence at the time of death. If Mr. Andrews dies as a Spanish resident without having made an express election, Spanish succession law will govern his estate.

Spanish succession law contains mandatory forced heirship rules — the legítima — under which two-thirds of the estate must be reserved for direct-line descendants (legitimarios), regardless of the testator's wishes. For a man with adult children from a prior marriage, this means that a significant portion of his estate cannot be diverted away from them, regardless of what his Will says.

The Succession Regulation permits an individual to elect, during their lifetime, for the law of their nationality to govern their succession instead of the law of habitual residence. For Mr. Andrews, as a British national, this means he can elect English law — which has no forced heirship rules. The election must be made expressly in a testamentary disposition (typically in the Will itself, or in a codicil or separate declaration) and must identify English law as the elected law.

An election of English law is a powerful tool: it removes the Spanish legítima constraint from assets that are not situated in Spain. But there is an important limitation: Spanish courts have shown some reluctance to apply the ordre public exception to override elections where the effect would be to deprive Spanish-domiciled children of forced heirship protection. And for Spanish real estate specifically, the lex situs principle may override even a valid Succession Regulation election in certain circumstances — Spanish courts may apply Spanish law to Spanish immovable property regardless.

ISD in Andalusia: A Favourable Regime

The Spanish inheritance and gift tax (Impuesto sobre Sucesiones y Donaciones, ISD) is a regional tax whose rates and reliefs vary significantly between Spain's autonomous communities. Andalusia has, in recent years, introduced one of the most generous ISD regimes in Spain for direct-line transmissions: a 99% bonus (bonificación) on the ISD quota for Group I (descendants under 21) and Group II (descendants 21 and over, plus ascendants and spouses) heirs.

In practical terms, this means that an inheritance from a Spanish-resident parent to a child or grandchild, where the estate is subject to Andalusian ISD, will attract virtually no inheritance tax. For an individual with a large estate choosing between Andalusia and other regions — or between Spain and another country — this is a significant planning advantage.

The Andalusian bonus applies to the cuota íntegra of the ISD after applying the state scale and the multiplying coefficient based on pre-existing wealth. It reduces the effective tax burden to approximately 1% or less, even on very large inheritances to direct-line heirs. This is a material consideration in the overall attractiveness of Andalusia as a destination.

The planning requirements for Mr. Andrews are extensive, multi-jurisdictional, and time-sensitive. No single measure will achieve the outcome alone: the optimal plan combines legal structure, timing discipline, and coordination between UK and Spanish advisers, all executed before Spanish residency is acquired.

The Beckham Law stands out as the centrepiece of the plan. If Mr. Andrews qualifies — and with careful structuring of his employment relationship with the PIF group, there is a strong basis for eligibility — the regime eliminates Spanish IRPF on his foreign-source income for up to six years. The salary from the PIF alone, taxed at 47% under ordinary IRPF versus 0% under Beckham Law on foreign employment income, represents a potentially enormous saving over the regime period.

The trust planning is secondary to the Beckham question, but not less important. If the trust deed reviews confirm that Mr. Andrews holds no attribution-risk powers and that the DGT's criteria for non-attribution are satisfied, the three settlements should sit outside his Spanish tax base entirely. But this conclusion can only be reached after a careful, document-by-document review — it cannot be assumed.

The window is fixed. Once the calendar year of arrival begins, the opportunity to restructure outside Spain's tax net begins to close. The discipline of pre-entry planning is precisely this: doing the work before the deadline, not after.
