This case documents a complete brief-to-escritura closing for a US technology founder relocating from San Francisco to Marbella following a Series B liquidity event. The full transaction took 14 weeks from first call to keys-in-hand and required pre-move tax restructuring (PFIC liquidation), Beckham Law special regime filing within the 90-day legal deadline, and a cash + 30-day completion structure that closed €420,000 below asking on a Cascada de Camoján villa. We publish this case because the PFIC trap on existing Spanish mutual fund holdings is the single most common silent error in US-founder Marbella relocations, and the documented sequencing here resolves it cleanly.

Client snapshot

The brief

The client engaged us in the second week of January 2026 with a brief that was unusually well-defined: a primary residence, fully detached, gated community access, 5 bedrooms minimum, modern build or recent renovation, completion before Q3 to allow school year registration for the September intake. Budget ceiling was €5M all-in (purchase + ITP + legal + setup). The driving relocation motive was a combination of US capital-gains rate trajectory concerns, school environment preference, and a US-Spain tax-treaty position the client's CPA had pre-validated. The Beckham Law special regime under Spanish IRPF article 93 was the central pillar of the relocation case.

The client had read enough to know two things mattered: the Beckham filing had to land within 90 days of registering as a Spanish tax resident, and the existing $2M Spanish-domiciled mutual fund position would, the moment they became a US-Spanish dual filer under Beckham, become a Passive Foreign Investment Company (PFIC) for US purposes. The PFIC regime would treat the fund's annual undistributed income as a deemed distribution at the highest marginal US rate plus an interest charge on prior years — a tax exposure their CPA estimated at roughly $180,000-$240,000 per year for as long as the fund was held.

The shortlist

We screened 41 properties across Cascada de Camoján, Sierra Blanca, La Zagaleta lower tier, and the upper Golden Mile detached segment. Twelve were viewed in two trip clusters (a 4-day February trip and a 3-day early-March return). The shortlist that survived to second viewing:

1. Sierra Blanca renovation candidate, €4.95M asking — 1,100 m² built, 1990s build with partial 2018 refresh, plot 2,200 m². Rejected because remaining renovation budget would have pushed all-in cost past €5.8M and delayed school enrollment.
2. Cascada de Camoján lower-tier villa, €4.5M asking — 720 m² built, 2019 build, plot 1,950 m². The eventual selection.
3. Lomas de Marbella Club, €4.2M asking — 850 m² built, 2014 build, plot 1,600 m². Rejected on lack of true gated-community status (privately managed urbanización rather than 24/7 manned gate).
4. La Zagaleta lower tier, €5.5M asking — over budget by €500K+ even before transaction costs; flagged but not pursued.

The Cascada villa won on a combination of (a) move-in condition with no renovation budget required, (b) the genuine 24/7 manned gate, (c) the south-facing plot orientation and direct sea view, and (d) a vendor situation we judged would accept a meaningful price discount in exchange for transaction certainty and speed.

The chosen property

The selected property was a 5-bedroom contemporary villa on Cascada de Camoján's lower elevation tier (the more accessible band of the urbanización, roughly 200-230m elevation, on the inner road closer to the main gate). Specifications:

• Built area: 720 m² across three levels plus a 180 m² basement (gym, cinema, wine room, staff bedroom)
• Plot: 1,950 m², landscaped, infinity pool, covered terrace, outdoor kitchen
• Bedrooms / bathrooms: 5 / 6
• Build year: 2019, by a Marbella developer with a clean post-completion record
• Energy certificate: B
• Asking price: €4,500,000
• Asking €/m² (built): €6,250
• Verified Tinsa zone median Q4 2025 (Cascada de Camoján): €7,640/m²

The asking €/m² was below the Tinsa median, which initially read as a green flag. Underwriting clarified the reason: the vendor was a non-resident family that had owned the villa as a secondary residence for six years, used it perhaps eight weeks per year, and had been quietly listing for nine months. The selling agent was a co-listing arrangement with two other agencies and the listing had grown stale. The vendor was paying roughly €4,500/month in IBI plus community plus pool/garden maintenance and had moved on emotionally from the asset. That combination — patient seller capacity exceeded, modest carrying cost ongoing, no urgency to capture last 5% of price — was the leverage point.

The tax setup

The tax architecture had three workstreams running in parallel through the legal process.

Beckham Law special regime — IRPF article 93

The Beckham Law (Real Decreto 687/2005 implementing IRPF article 93) allows qualifying inbound workers and certain administrators to elect taxation as non-residents on worldwide income for 6 years, with Spanish-source employment income taxed at the flat 24% rate up to €600,000 (47% above). For a founder with most personal compensation arriving as US dividends and capital gains, the headline value is that non-Spanish-source income is excluded from the Spanish IRPF base for those 6 years (with limited exceptions, principally Spanish-source employment income).

The 2023 Ley de Fomento del Ecosistema de las Empresas Emergentes (Startups Law) reduced the prior-residence look-back from 10 years to 5 years and added eligibility paths for entrepreneurs and remote workers. For this client, the qualifying path was as a director of his US company (the C-corp the founder retained an executive seat on post-secondary), with the formal Spanish employment relationship created via a Spanish entity established in week 6.

The filing deadline is strict: 6 months from the date of registration with Spanish Social Security, or alternatively, with the Spanish Tax Agency's communication of the start of activity in Spain, with the practical guidance from AEAT that the optimal window is within 90 days of habitual residence formation. We filed Modelo 149 on day 87 of the relocation timeline. Late filing is fatal — there is no remedial path.

The PFIC trap and resolution

The client's $2M Spanish-domiciled equity fund (FI registered in Madrid, distributing class) was, in US tax classification, a passive foreign investment company. Under US IRC §§1291-1298, a US person holding PFIC shares is subject to one of three regimes: the default §1291 excess-distribution regime (highest marginal rate + interest charge on accumulated income, treated as deemed distributions in the year of disposition), the §1295 Qualified Electing Fund (QEF) election (annual current-income inclusion at ordinary rates, available only if the fund provides annual PFIC Annual Information Statements — most Spanish FIs do not), or the §1296 mark-to-market election (available for marketable PFICs, annual mark-to-market gain at ordinary rates).

For this fund, the QEF election was unavailable (the fund did not produce PFIC Annual Information Statements) and the mark-to-market election was theoretically available but produced unattractive ordinary-rate treatment of unrealized gains. The CPA's calculation, validated by our Marbella-side asesoría fiscal: continuing to hold the fund post-move would produce $180K-$240K per year of US PFIC tax leakage.

The resolution was sequencing: liquidate the entire position before establishing Spanish tax residency. Liquidation in the US tax year preceding the move triggered standard long-term capital gains at the US rate on the realized appreciation, payable in the next US filing — a known, bounded cost. Once liquidated and held in cash, the proceeds were no longer PFIC-classified and could be redeployed post-move into the villa purchase and into US-domiciled ETFs (which are not PFICs for the US owner). The CPA executed the liquidation in early February. Total realized gain: roughly $640K. Total US federal tax cost of liquidation: roughly $152K. Comparative cost of holding for 6 Beckham years: roughly $1.1M-$1.4M. Net savings from the pre-move liquidation: ~$1M.

This is the single most common silent failure in US-founder Marbella relocations. The Beckham Law does not protect against US-side PFIC consequences — Beckham is a Spanish-side instrument. The US filing chain runs in parallel and is unaffected by the Spanish election.

ITP, IBI, IRNR baseline

The Andalucía ITP rate on second-hand residential property is 7%, applied to the higher of declared price or Junta valor de referencia. For the villa, the valor de referencia was within 4% of agreed price, so the declared transaction price was the base. ITP payable: 7% × €4,080,000 = €285,600. Notary + registry + asesoría / abogado fees totalled roughly €34,000. Total transaction costs above purchase: €319,600, or 7.83% of purchase price.

Going-forward IBI on the villa was set at €11,400/year; community fees €4,800/year; pool and garden maintenance contract €18,000/year; insurance €5,200/year. Annual carrying cost (ex utilities and ex Beckham IRPF): approximately €39,400.

The legal process timeline

The Beckham Modelo 149 was filed on day 87 from habitual residence formation — 3 days inside the 90-day soft deadline our asesoría operates as standard policy.

What went wrong

Three things did not go to plan.

First, the initial vendor's bank declined the first reservation deposit wire. The Spanish solicitor's client account was at Sabadell, the vendor's account was at a smaller cooperative bank in Madrid, and the wire (originated from a Wise multi-currency account on the US side) was held in compliance review for 11 days. We solved by re-routing the second tranche (the bulk of the purchase price) directly from a Spanish-domiciled CaixaBank account opened in week 9 by the client, with proof-of-funds documentation (signed bank statements covering the prior 6 months from the US brokerage, plus the CPA letter documenting the PFIC liquidation as the source of the wire) pre-cleared with CaixaBank's KYC desk. Lesson: open a Spanish bank account in the buyer's name before completion, even if you intend to fund from offshore.

Second, the topographic survey revealed a 0.3-metre boundary discrepancy on the south-east plot edge with the neighbouring villa. Specifically, a section of the pool patio sat marginally over the registry-recorded boundary line as captured in the 2019 first registration. The neighbour was contacted, the discrepancy was acknowledged in writing as a longstanding non-objection, and a vendor declaration plus an acta de manifestaciones was filed at the notary to put it on the record. Not a transaction blocker — but a reminder that registry coordinates and physical reality on Marbella hillside plots regularly diverge by 0.2-0.5m. Always survey.

Third, the Beckham Modelo 149 nearly tripped on the employment-relationship qualification. The first draft of the Spanish SL's contract with the client described his role too loosely ("estrategia y desarrollo"), and the asesoría's pre-submission review flagged it as potentially insufficient under the Startups Law's tightened criteria for director-track Beckham qualification. The contract was rewritten to specify board director responsibilities, decision-making authority, and reporting structure with documentary backup. Re-submission cleared. If the original draft had gone in and been challenged, the remediation window would have been narrow.

The closing economics

The closing €/m² at 74% of the verified Tinsa zone median was driven primarily by vendor situation (stale listing, non-resident, carrying-cost fatigue) and secondarily by the speed-and-certainty premium the cash + 30-day-completion structure delivered. We would expect 85-95% of zone median to be the realistic ceiling for a comparable buyer without those vendor dynamics.

Year-1 review

At the 12-month mark from escritura, the family had completed full Spanish school enrollment (both children placed at the originally targeted international school), the Beckham election was operating cleanly through its first IRPF cycle (Modelo 151 filed, US-source dividend income excluded from the Spanish base), the PFIC exposure was zero (no PFIC holdings remained), and US filing through the CPA continued unaffected. Annual carrying cost on the villa landed at €41,800 (slightly above the €39,400 underwriting estimate, driven by higher-than-expected pool servicing). The family had not sold the San Francisco residence (held as rental, with US-side property management) — a deliberate hedge against re-pivoting back inside the 6-year Beckham window.

The single significant downstream issue: a misfiled Modelo 720 in the first US-asset disclosure year, corrected via supplementary filing within the AEAT remediation window with no penalty. Modelo 720 obligations for US persons with retained US accounts above the €50,000 thresholds are easy to misjudge in year one and worth flagging early.

Why this matters for similar buyers

US tech founders relocating to Marbella sit at the intersection of two unforgiving tax systems (US worldwide citizenship-based taxation, Spanish AEAT) with a 90-day Beckham filing window that is fatal if missed and a PFIC regime that will quietly compound losses on any non-US-domiciled fund position carried across the move. The sequencing template — pre-move PFIC liquidation, Spanish entity incorporation in the first 30 days, Beckham filing inside 90 days, US/Spain CPA coordination that maps the two filing calendars onto one operational schedule — is replicable. The discount opportunity on Cascada / Sierra Blanca trophy stock from non-resident vendors with stale listings is also replicable, in the right vendor-situation conditions. For founders in the $10M-$30M post-exit liquidity band targeting €3M-€6M Marbella primary residences, the workflow documented here is the production line.
