Do I actually have to pay the French exit tax in cash when I leave?

Often not. A payment deferral (sursis de paiement) applies automatically for moves to EU states and to countries with adequate tax cooperation agreements; other destinations may require appointing a representative and providing guarantees. The assessed tax is then cancelled if you hold the securities for 2 years after departure (5 years for portfolios above 2.57 million euros), or if you return to France still holding them.

France to Portugal or Dubai: The Expatriation Guide (Exit Tax, IFI, Timing)

Q: Who pays the French exit tax?

Article 167 bis applies if you were a French tax resident for at least 6 of the 10 years before departure and you either hold securities representing at least 50% of a company's profits or your total securities portfolio exceeds 800,000 euros. Latent capital gains are assessed on departure at the flat tax (12.8% income tax plus social contributions, a combined rate around 30 to 31 percent under the 2026 rules, to be confirmed against the current finance act).

Q: What happens to French wealth tax (IFI) when I leave?

The IFI only taxes real estate. As a non-resident you remain liable only on French real estate assets above the 1.3 million euro threshold; your foreign property falls out of scope. New residents arriving in France get a 5-year exemption on foreign real estate, which matters in the other direction. Selling or restructuring French property is often part of the exit design.

Q: Portugal or Dubai for a French leaver?

Portugal offers proximity, EU rights and the IFICI regime: 20% on eligible Portuguese professional income and exemption on most foreign investment income for 10 years, but only for qualifying activities. Dubai offers zero personal income tax, no CGT and a fast visa system, at the price of distance and higher costs. High earners with portable businesses often choose Dubai; families and EU-attached professionals lean Portugal. The tiebreaker is usually lifestyle, not tax.

Zero Tax · Updated July 2026 · 9 min read

A Lyon founder sold 20% of his company and planned to move to Lisbon the following spring, sell the rest from abroad, and enjoy the difference. His notaire asked one question that reordered the whole plan: had he counted his portfolio against the 800,000 euro exit tax threshold? He had not. The move still happened, and legally so did the savings, but the sequence (what to sell, when to leave, what to defer) was rebuilt from scratch.

The French exit tax: who is caught

Article 167 bis of the French tax code assesses latent capital gains on securities when you transfer your tax residence out of France. You are in scope if:

you were a French tax resident for at least 6 of the 10 years preceding departure, and
you hold securities representing at least 50% of a company's profits, or your total securities portfolio exceeds 800,000 euros.

The assessed gain is taxed at the flat tax (PFU): 12.8% income tax plus social contributions, a combined rate of around 30 to 31 percent under the 2026 finance act (exact social rate to be confirmed against current law). Crucially, this is an assessment, not necessarily a payment.

The deferral and the escape hatches

Sursis de paiement: payment is automatically deferred for moves to EU member states and to jurisdictions with adequate cooperation agreements with France; other destinations can require a fiscal representative and guarantees. Where Dubai falls for your case depends on the applicable agreements at your departure date; it must be checked, not assumed.
Cancellation by holding: the exit tax is wiped if you still hold the securities 2 years after departure (portfolios up to 2.57 million euros) or 5 years (above that), or if you return to France still holding them.
Actual sale while abroad: sell within the monitoring window and the deferred French tax becomes payable, with credit mechanics against foreign tax depending on treaties.

The design is transparent: France does not want to stop you leaving, it wants to stop you leaving just before a sale. Anyone planning an exit-then-sell sequence must build around the 2-year or 5-year clock.

The detail nobody weighs: the exit tax freezes a photograph of your portfolio on departure day, and the finance bill debate in Paris revisits this regime almost every autumn (a 2026 amendment to restore the old 15-year holding period was proposed and dropped). The rules you leave under are the rules that generally stick to your file, which is a real argument for executing a planned exit sooner rather than watching another budget cycle. Confirm the current text before you book the movers, then move once, cleanly.

IFI: the wealth tax that mostly stays behind

France's IFI taxes only real estate wealth above 1.3 million euros. Leaving improves the picture immediately:

As a non-resident you remain liable on French real estate only; foreign property leaves the base.
Rental income from French property remains taxable in France, with minimum rates for non-residents.
Many leavers restructure or sell French property as part of the exit, both for IFI and for succession planning under French forced heirship rules, which do not disappear with residency.

Portugal or Dubai: the honest comparison for French leavers

	Portugal (IFICI)	Dubai (UAE)
Personal income tax	20% on eligible Portuguese professional income; most foreign investment income exempt for 10 years	None
Capital gains	Foreign gains generally exempt under the regime; Portuguese gains taxable	None at personal level
Eligibility	Qualifying activities only (tech, science, R&D, startups); not resident in Portugal in prior 5 years	Visa via employment, company setup, property (AED 2M golden visa) or remote work
Distance and life	2 hours from Paris, EU rights, Francophone-friendly	7 hours, non-EU, higher cost but zero-tax ecosystem
Treaty with France	Yes, long-standing	Yes, in force since the 1990s

Pattern from real cases: founders and traders with portable, high-margin income choose Dubai for the flat zero and the banking hub. Families, professionals in eligible sectors and anyone attached to EU life choose Portugal and accept 20% on local activity as the price of proximity. Both work; they solve different lives.

The clean-exit sequence from France

Inventory securities against the 50% and 800,000 euro thresholds, and date your 6-of-10-years residency count.
Decide what to sell before departure (taxed in France at known rates) versus after (under the exit tax clocks).
Choose the destination and secure its status first: IFICI registration window in Portugal, visa and presence plan in the UAE.
File the exit tax forms (2074-ETD) with the departure-year return, with deferral requests and guarantees where needed.
Resolve French real estate: keep (IFI and non-resident rates), sell, or restructure.
Document the new residence (home, days, certificate) for treaty purposes; France challenges paper exits, not real ones.

Frequently asked questions

Who pays the French exit tax?

Residents of 6 of the last 10 years holding 50% of a company or a securities portfolio above 800,000 euros. Latent gains are assessed at the flat tax on departure (around 30 to 31 percent combined under the 2026 rules, to be confirmed).

Do I actually have to pay it in cash when I leave?

Often not: payment is deferred automatically for EU and cooperative destinations (guarantees may be needed elsewhere), and the tax is cancelled after 2 years of holding (5 years above 2.57 million euros) or upon return.

What happens to French wealth tax (IFI) when I leave?

Non-residents pay IFI only on French real estate above 1.3 million euros. Foreign property drops out of the base, which is why property restructuring is often part of the exit.

Portugal or Dubai for a French leaver?

Portugal: proximity, EU rights, IFICI at 20% with foreign income exemptions, for eligible professions. Dubai: zero personal tax and speed, at the cost of distance. The decision is usually about life design, with tax as the multiplier.
