Client Profile

Detail Info
Name Alexandre (anonymized)
Age 34
Nationality French
Residence Paris, France (12 years)
Situation SaaS startup founder, received €2M acquisition offer
Family Single, no dependents

The Problem

Alexandre built a SaaS startup over 5 years. A German acquirer offered €2M for 100% of the shares.

If he sold in France:

Tax Rate Amount
Capital gains (flat tax PFU) 30% €597,000
CEHR (high income surtax) 3% ~€59,700
Total French tax ~€656,700

After tax: ~€1,343,300

Alexandre came to us 8 months before the deal was expected to close, asking: "Is there a legal way to reduce this?"


The Solution

Phase 1: Pre-Departure Setup (Month 1-3)

Destination: Dubai (UAE)

Action Timeline Cost
Dubai Freezone company (IFZA) 2 weeks €5,200
UAE residency visa 2 weeks Included
Emirates ID 1 week Included
Wio bank account (personal) 3 days Free
Emirates NBD account (business) 2 weeks €1,800

Phase 2: Fiscal Transfer (Month 4)

Action Detail
Transfer fiscal domicile Moved to Dubai, terminated French lease
Exit tax declaration (2074-ETD) Declared €1,990,000 latent gain on startup shares
Sursis automatique Activated — France-UAE tax treaty
Established genuine residency Apartment lease, Emirates ID, utility bills

Phase 3: Wait Period (Month 4-20)

Alexandre held his shares for the required period. Since he held ≥50% of the company, the 5-year rule applied.

However — Alexandre's plan was different. He didn't want to wait 5 years. He wanted to sell quickly.

Phase 4: The Sale (Month 8)

Alexandre sold his shares 4 months after leaving France.

Tax event Detail
Sale of shares €2M, while exit tax sursis was active
Exit tax triggered Yes — sale during sursis period
Tax owed to France 30% of the lesser of: latent gain at departure OR actual gain at sale
Actual gain at sale Same: ~€1,990,000
Exit tax due €597,000
UAE tax on the gain €0

Wait — so he paid the same amount?

No. Here's where the planning mattered.

The Optimization: Apport-Cession (Article 150-0 B ter)

Before leaving France, Alexandre contributed his startup shares to a holding company (SAS) he created, in exchange for holding company shares. This is an apport-cession — a well-established French tax mechanism.

Step Detail
Created SAS Holding Before departure
Contributed startup shares to Holding Asset swap (apport) — no immediate tax
Exit tax calculated On the holding company shares (same latent gain)
Holding company sells the startup Post-departure, from France
Reinvestment obligation 60% of proceeds reinvested within 2 years in qualifying economic activity

Result:

Element Amount
Sale proceeds €2,000,000
60% reinvested (in new SaaS project via Dubai company) €1,200,000
40% freely available €800,000
Exit tax on the apport Deferred (sursis maintained via reinvestment)
UAE tax on proceeds €0
Effective tax paid €0 (as long as reinvestment conditions met)

Timeline

Month 0    → Engaged Private Office
Month 1-3  → Dubai setup (company, visa, banking)
Month 4    → Fiscal domicile transferred
Month 4    → Exit tax declaration filed (sursis active)
Month 8    → Holding sells startup shares
Month 9    → Proceeds received by holding
Month 10   → Reinvestment begins (new project via Dubai entity)
Month 24   → 60% reinvestment deadline met
Month 60   → Exit tax on original apport → dégrèvement (cancellation)

Final Numbers

Scenario Tax paid Net proceeds
Sell in France, no planning €656,700 €1,343,300
Relocate + apport-cession + reinvestment €0* €2,000,000
Savings €656,700

*Conditional on maintaining reinvestment for 2 years and holding for 5 years post-departure.

Key Takeaways

  • The exit tax doesn't have to be a barrier — with proper planning, it can be legally managed
  • Apport-cession requires genuine reinvestment — this isn't a paper exercise
  • The 60% reinvestment rule means the founder must actually deploy capital into a new project
  • Starting the process 8-12 months before a sale is ideal — last-minute planning limits options
  • Genuine establishment of foreign residency is non-negotiable
