Marbella Post-Exit Tech Founder on the IRNR Non-Resident Tax (Real Decreto Legislativo 5/2004)

TL;DR

Fit rating: 6/10 (viable but requires specific structuring)

• Top reason this works. IRNR Non-Resident Tax (Real Decreto Legislativo 5/2004) is workable but not the obvious choice for a post-exit founder. Second-home buyers retaining primary residence and tax base in source country; investors holding spanish property without local residency — the post-exit founder brief sits at the edge of this fit.
• Where it can break. The honest caveat: IRNR Non-Resident Tax (Real Decreto Legislativo 5/2004) has a trap most buyers underestimate — the 3% retention at sale (paid by the Spanish buyer to the Spanish tax authority on behalf of the non-resident seller) is a cash-flow consideration at exit.
• Typical ticket range for this persona. €3 million to €18 million.
• Default zones. Sierra Blanca, La Zagaleta, Sotogrande, Nueva Andalucia.

Why a post-exit founder ends up structured under IRNR

The Post-Exit Tech Founder cohort is characterised by founder of a recently-exited software or technology company, typically aged 35-50, with primary liquidity event in the prior 24 months and a brief that prioritises European time-zone base, optional remote work continuity, and tax-efficient long-term residency. The core operational need is tax-efficient European base with full-fibre connectivity, IB-pathway schools for school-age children, and Marbella-network access without dynasty-wealth status performance.

IRNR Non-Resident Tax (Real Decreto Legislativo 5/2004) works for this cohort because: the Spanish non-resident tax regime applicable to foreign tax residents owning Spanish property — 24% on Spanish-source rental income for non-EU residents (19% for EU/EEA residents), and imputed-rent taxation on Spanish property kept for personal use.

Qualifying test: Spanish tax non-residency — i.e. fewer than 183 days in Spain, centre of economic interests outside Spain, no Spanish-resident immediate family.

Duration of regime: indefinite, conditional on continuing non-residency.

The specific value of IRNR for a post-exit founder is structural: the regime aligns with how this cohort actually generates, holds and deploys capital. The post-exit founder brief is not simply about buying a Spanish villa — it is about embedding Spanish presence into a wider personal-and-corporate-tax structure that continues to operate across borders.

What the numbers actually look like at this combination

A typical post-exit founder brief in 2026 falls in the €3 million to €18 million ticket range, with the bulk of transactions clustered in €4.2 million to €9 million.

Under IRNR, the headline tax implications for that ticket band:

• Acquisition cost. Spanish ITP (resale transfer tax) of 7% in Andalucia for properties under €1m, sliding to 8-9% above, OR IVA (new-build VAT) of 10% plus AJD (stamp duty) 1.2% for first-purchase new-build. Add notary, registry and gestor fees of €4,000-€18,000 depending on ticket size and structure complexity.

• Annual holding cost under IRNR. IRNR non-resident: 19% (EU/EEA) or 24% (non-EU) on Spanish-source rental income; imputed-rent tax on personal-use property; 3% retention on disposal applied to gross sale price.

• Disposal under IRNR. Spanish CGT 19-26% on the gain (calculated as sale price minus acquisition cost plus capital improvements minus selling costs), with the 3% non-resident retention applicable on the gross sale price on exit.

For perspective, a post-exit founder on a €10.5 million purchase under IRNR should expect total transaction friction (acquisition + 5 years of annual holding + disposal) of approximately €1.9 million to €2.9 million across the cycle, depending on rental strategy and Patrimonio exposure.

What a post-exit founder should specifically look for when structuring under IRNR

The generic Marbella tax-structuring checklist applies. Layered on top, five post-exit founder-specific factors matter under IRNR:

1. Pre-purchase residency planning. Spanish tax non-residency — i.e. fewer than 183 days in Spain, centre of economic interests outside Spain, no Spanish-resident immediate family. The mistake most post-exit founders make is purchasing first and applying for the regime second; the correct sequence is the reverse. Spanish gestor and source-country tax adviser should be coordinating three to nine months before the reserve contract.

2. Title structure and deed naming. Under IRNR, the legal title can be taken in personal name, joint marital name, Spanish-resident corporate vehicle, or foreign-vehicle (UK SPV, Luxembourg, Netherlands BV). Each has different annual and disposal-tax implications. For a post-exit founder, the default is personal name with source-country residency retained.

3. Pre-purchase asset-and-structure mapping. A post-exit founder typically holds a residual founder share package, vested options, secondary-market exit proceeds, and a discretionary investment portfolio — each with different PFIC / CFC / Spanish-trust-recognition treatment. Spanish-side recognition of each layer determines the IRNR cost and benefit profile.

4. Five-year-plus horizon plan. IRNR Non-Resident Tax (Real Decreto Legislativo 5/2004) runs on indefinite, conditional on continuing non-residency. Plan the post-exit founder exit-or-extension decision at year 4 of the regime, not year 6 — restructuring after expiry is materially more expensive than planning the transition ahead.

5. Gestor selection. Not every Marbella gestor handles IRNR regularly. Confirm before engagement that the firm has at least 20 active IRNR files for clients similar to the post-exit founder brief. Beckham, IRNR and Andalucia Patrimonio specifically benefit from specialist practice depth; the generalist Spanish gestor will not catch the cohort-specific nuances.

What to avoid

• The 3% retention at sale (paid by the spanish buyer to the spanish tax authority on behalf of the non-resident seller) is a cash-flow consideration at exit. This is the single most common reason post-exit founders end up restructuring within 18 months of purchase.
• Mixing IRNR with a structure that breaks qualifying tests. IRNR: do not let your day-count in Spain drift toward 183 without explicit gestor advice — accidental residency triggers worldwide-income disclosure.
• Acquiring through the wrong corporate vehicle. A foreign holding company that worked in another jurisdiction may trigger Spanish PIT-DAC reporting, CFC rules, or substance challenges. Check with Spanish gestor before transferring the purchase deposit.
• Underestimating Spanish wealth-and-inheritance reporting. Even under IRNR, Modelo 720 (foreign asset reporting) applies to Spanish residents with foreign assets above €50k per category. Filing failures carry substantial penalties.

Five property briefs for the post-exit founder cohort under IRNR

These are descriptive briefs, not real listings, calibrated to a post-exit founder structured under IRNR in mid-2026.

1. The entry-tier base property. €3 million to €4.5 million: smaller villa or large apartment matching tax-efficient European base with full-fibre connectivity, IB-pathway schools for school-age children, and Marbella-network access without dynasty-wealth status performance, structured for clean IRNR filing from year one.
2. The mid-tier family compound. €5.4 million to €7.2 million: 4-6 bedroom villa with garden, pool, and the discipline-specific infrastructure post-exit founder buyers need, in a default zone for the cohort.
3. The upper-tier trophy property. €9 million to €18 million: bespoke or off-market property with full personal-residence-plus-guest-capacity for the cohort's extended-family or hosting brief.
4. The structured-holding investment. Where IRNR permits, a separately-titled rental property generating yield outside the primary residence — usually held in distinct vehicle for tax and succession reasons.
5. The bridge apartment. Smaller €3.3 million apartment used as Marbella base during the first 12-18 months of IRNR regime while villa search converges.

IRNR Non-Resident Tax (Real Decreto Legislativo 5/2004) in operational detail for the post-exit founder cohort

The regime's working summary. The spanish non-resident tax regime applicable to foreign tax residents owning spanish property — 24% on spanish-source rental income for non-eu residents (19% for eu/eea residents), and imputed-rent taxation on spanish property kept for personal use.

Qualifying tests at the start. Spanish tax non-residency — i.e. fewer than 183 days in spain, centre of economic interests outside spain, no spanish-resident immediate family.

Best fit profile. Second-home buyers retaining primary residence and tax base in source country; investors holding spanish property without local residency.

Duration and renewal. Indefinite, conditional on continuing non-residency.

The most common trap. The 3% retention at sale (paid by the spanish buyer to the spanish tax authority on behalf of the non-resident seller) is a cash-flow consideration at exit.

For a post-exit founder, the practical interpretation is that IRNR is a workable structure that requires careful upfront planning to align with the cohort brief.

Realistic timeline from post-exit founder brief to IRNR filing

• Months -9 to -6. Source-country tax adviser and Spanish gestor coordinate residency-decision framework. Pfic exposure on residual share holdings, source-country exit-tax timing, spanish-side trust-and-corporate-structure recognition gaps.
• Months -6 to -3. First viewing trip (8-14 properties matched to post-exit founder brief), NIE application, Spanish bank account, school applications (if school-age children).
• Months -3 to 0. Shortlist narrowed, structural and legal due diligence on chosen property, reserve contract signed, residency-filing prep aligned with IRNR qualifying tests.
• Closing month. Notario appointment, Spanish ITP/IVA paid, change of utilities, community-fee handover.
• Months +1 to +6. IRNR filing (specifically Form 030 + Beckham declaration / Modelo 100 IRPF / Modelo 210 IRNR / Modelo 714 Patrimonio as applicable), Modelo 720 if applicable, first quarterly tax payments.

Total elapsed time from first call to first IRNR filing for a post-exit founder is typically 9-15 months, depending on residency-restructuring complexity.

FAQs — post-exit founder on IRNR

Q: Is IRNR actually a good fit for a post-exit founder?

A: It is workable but not the obvious fit. Second-home buyers retaining primary residence and tax base in source country; investors holding spanish property without local residency — the post-exit founder brief sits at the edge of this fit.

Q: What does IRNR actually do for a post-exit founder?

A: The spanish non-resident tax regime applicable to foreign tax residents owning spanish property — 24% on spanish-source rental income for non-eu residents (19% for eu/eea residents), and imputed-rent taxation on spanish property kept for personal use.

Q: What is the main trap of IRNR for the post-exit founder cohort?

A: The 3% retention at sale (paid by the spanish buyer to the spanish tax authority on behalf of the non-resident seller) is a cash-flow consideration at exit. The post-exit founder-specific risk on top of that is PFIC exposure on residual share holdings, source-country exit-tax timing, Spanish-side trust-and-corporate-structure recognition gaps.

Q: What is the typical ticket range for a post-exit founder structured under IRNR?

A: €3 million to €18 million, with the bulk of transactions clustered €4.2 million to €9 million.

Q: Can I switch from IRNR to another regime later?

A: Yes — the regimes are not permanent for most cohorts. Beckham Law is fixed at 6 years; IRNR and normal IRPF flip based on the residency test each year; Andalucia Patrimonio bonificacion follows the Andalucia residency tests. Golden Visa transition holders should track renewal milestones at year 2 and year 5. Plan the transition decision in advance — restructuring on the back foot is materially more expensive than planning ahead.
