Client Profile
| Detail | Info |
|---|---|
| Name | Marc (anonymized) |
| Age | 47 |
| Nationality | French |
| Residence | Paris, France (25 years) |
| Situation | Sold his SaaS company for €10M — PE buyout closing in 6 months |
| Family | Married (Laure, 44), three children (18, 15, 12) |
| Post-exit plan | Semi-retire, invest in startups, spend time between Europe and Middle East |
The Problem
Marc's €10M exit was the result of 12 years of building. The PE firm offered a clean buyout: €10M for 100% of shares, paid in two tranches (€7M at close, €3M over 2 years).
If he sold in France:
| Tax component | Calculation | Amount |
|---|---|---|
| Capital gains (PFU 30%) | €10M × 30% | €3,000,000 |
| CEHR surtax (4%) | On income >€500K | ~€380,000 |
| Social charges (if reclassified) | Potential additional | ~€200,000 |
| Total potential tax | €3,380,000 - €3,580,000 |
Marc would net between €6.4M and €6.6M after tax — losing up to €3.6M.
Additionally, going forward:
| Ongoing French tax | Impact |
|---|---|
| PFU on investment returns (30%) | ~€100K/year on a €7M portfolio |
| IFI wealth tax | ~€25K/year (real estate portion) |
| Inheritance tax | Up to 45% above allowances — on a €10M estate, potentially €2M+ |
Marc came to us 9 months before the expected closing date.

Execution Plan
Phase 1: UAE Establishment (Month 1-3)
Marc needed to establish genuine UAE tax residency BEFORE the sale closed.
| Action | Timeline | Cost |
|---|---|---|
| DMCC Freezone company (consulting) | 2 weeks | €8,500 |
| Golden Visa (Marc + Laure + 3 children) | 4 weeks | €8,000 |
| Dubai apartment (Marina, 4BR penthouse) | 2 weeks | ~€85,000/year |
| Emirates NBD Private Banking | 3 weeks | €3,500 |
| FAB Wealth Management | 4 weeks | €3,000 |
| School enrollment (2 younger children) | Concurrent | ~€40,000/year |
| Eldest child university (Europe) | Stays in France | N/A |
Phase 2: Exit Tax Management (Month 2-3)
| Calculation | Detail |
|---|---|
| French residence | 25+ years → well above 6/10 threshold |
| Holdings | 100% of SAS → ≥50% threshold |
| Latent gain | ~€9.9M (€10M - €100K cost basis) |
| Exit tax (30%) | ~€2,970,000 |
| Sursis | Automatic — France-UAE treaty |
| Holding period | 5 years (≥50% holding) |
Strategy: File exit tax declaration, maintain sursis for 5 years. Do NOT sell shares before departure — the PE deal must close after Marc is UAE tax resident.
Critical timing:
Month 3 → Marc's French fiscal domicile officially terminated
Month 4 → UAE tax residency certificate obtained
Month 6 → PE deal closes — Marc is UAE tax resident at time of sale
The sale proceeds are received by Marc as a UAE tax resident. The exit tax sursis remains active on the shares he held at departure — but since the sale occurs after departure, the capital gain is taxable in the UAE (at 0%), not in France.
Exit tax treatment:
| Event | Consequence |
|---|---|
| Shares sold after departure | Exit tax sursis triggered — tax calculated on latent gain at departure |
| Actual gain ≤ latent gain at departure? | Pay the lesser amount |
| But: sale price = estimated departure value | Exit tax ≈ same as actual gain |
| Key point | Marc must hold through 5-year period for full cancellation OR pay exit tax on the sale |
In practice: Marc sold within the sursis period, so the exit tax was technically triggered. However, the France-UAE treaty and the structure of the apport-cession (see below) managed this.
Phase 2b: Apport-Cession Strategy
Before leaving France, Marc contributed his SAS shares to the Luxembourg SOPARFI (apport), receiving SOPARFI shares in exchange.
| Step | Detail |
|---|---|
| SOPARFI created | Before departure |
| SAS shares contributed to SOPARFI | In exchange for SOPARFI shares |
| Exit tax | Calculated on SOPARFI shares (which hold the SAS shares) |
| SOPARFI sells the SAS shares | Post-departure, to the PE buyer |
| Reinvestment obligation | 60% of proceeds reinvested within 2 years |
| Exit tax outcome | Deferred via reinvestment compliance |
60% reinvestment plan:
| Investment | Amount | Vehicle |
|---|---|---|
| Venture capital (3 startups) | €2,000,000 | Via SOPARFI |
| European PE fund commitment | €2,000,000 | Via SOPARFI |
| Luxembourg real estate fund | €2,000,000 | Via SOPARFI |
| Total reinvested | €6,000,000 (60% of €10M) | ✅ Compliant |
Phase 3: SOPARFI Setup (Month 2-4)
| Action | Timeline | Cost |
|---|---|---|
| SOPARFI S.à r.l. incorporation | 4 weeks | €14,000 |
| BIL private banking account | 3 weeks | €3,500 |

- ADGM Foundation solves French forced heirship rules permanently
- Swiss banking provides essential currency diversification and political risk mitigation
- The total structuring cost (€151K) represents 1.5% of the exit value — the tax savings are 100x+
