Starting a Business in Dubai from France (2026): Exit Tax, CFC and Residency

Incorporating a company in Dubai does not, by itself, change where you or your company are taxed in France. A Dubai trade licence is a registration, not a residency event. Five French mechanisms decide your real position: your personal tax residency under article 4 B of the Code general des impots; your company's residency through its siege de direction effective; the exit tax of article 167 bis on unrealised share gains; the controlled-foreign-company rules of articles 209 B and 123 bis; and the 1989 France-UAE treaty. A genuine, substance-backed move can be highly efficient. A paper move that leaves management in France triggers exit tax, CFC attribution or a French-residency requalification of the Dubai entity.

This guide sets out how a French-resident founder should sequence those five gates before they set up a company in Dubai from France. For the UAE-side picture, our pillar on Dubai company formation across mainland, free zone and offshore covers the structures referenced below.

Key Takeaways

• You stay a French tax resident until you genuinely break article 4 B; a 90-day UAE domestic residency does not break it, and a treaty residency certificate generally needs 183 days of presence (Legifrance, 1990).
• The exit tax of article 167 bis crystallises unrealised gains where your holdings exceed EUR 800,000 or represent at least 50% of a company's profits, with a six-of-ten-years residency condition (Legifrance, 2026).
• Moving to the UAE, deferral of that exit tax requires a fiscal representative and a guarantee equal to 12.8% of the gains; relief follows after two years, or five if value exceeds EUR 2.57 million (Legifrance, 2026).
• A Dubai company managed from France is French-taxable under article 209-I; the UAE 9% rate clears the 40%-lower "privileged regime" test against France's 25%, so real substance is the whole defence (BOFiP, 2026).
• The 1989 treaty is favourable but bounded: dividends carry a 5% withholding cap for shareholders holding more than 25%, and gains on a participation above 25% are taxed in the company's residence state, not blanket zero (Legifrance, 1990).
• UAE corporate tax is 0% on taxable income up to AED 375,000 and 9% above (UAE Ministry of Finance, 2026); there is no UAE personal income tax.

Does opening a company in Dubai mean you stop paying tax in France?

No. Incorporating in Dubai changes where your company is registered, not where it or you are taxed. France taxes residents on worldwide income, and a French-resident founder running a UAE company stays inside the French net until each of the five gates is genuinely cleared. The UAE charges 0% corporate tax up to AED 375,000 and 9% above (UAE Ministry of Finance, 2026), but that rate only matters once your French exposure is properly closed.

Think of the licence and the tax outcome as two separate things. The trade licence is fast and procedural. The tax outcome turns on facts that the licence never touches: where you live, where the company is really run, what you owned on the day you left, and what the treaty actually assigns. Get the sequence right and the move is clean. Get it wrong and France keeps taxing you, the company, or both.

Across the French-founder files we handle, the recurring failure is not the Dubai setup. It is treating the trade licence as the finish line and skipping the exit-tax filing and the substance build. Those two omissions cause more reassessments than any free-zone choice.

Citation capsule: Incorporating in Dubai does not change French taxation by itself. France taxes residents on worldwide income, and the UAE charges 0% corporate tax up to AED 375,000 and 9% above (UAE Ministry of Finance, 2026). The outcome turns on five French gates the trade licence never touches: personal residency, company residency, exit tax, CFC rules and the treaty.

Are you still a French tax resident after moving to Dubai?

You remain a French tax resident if any single test in article 4 B of the CGI is met: your home (foyer) is in France, your principal stay is there, you carry on professional activity there, or France is your centre of economic interests (Legifrance, 1990). One test is enough. Meeting the UAE's 90-day domestic residency rule does not, on its own, break French residency.

The 90-day domestic rule versus the 183-day treaty certificate

Two UAE numbers get confused. The UAE grants domestic tax residency at 183 days, or at 90 days for UAE and GCC nationals and permit-holders meeting conditions, under Cabinet Decision 85 of 2022. A treaty tax residency certificate, the document you actually need to invoke the France-UAE treaty, generally requires 183 days of physical presence. So a 90-day stay may make you a UAE resident in name while leaving you fully exposed in France.

Why the treaty tie-breaker still has to be won

If both states claim you, the treaty tie-breaker in Article 4 decides: permanent home, then centre of vital interests, then habitual abode, then nationality, then mutual agreement (Legifrance, 1990). A founder who keeps a French home, French school-age children and a French management role can hold a UAE certificate and still lose the tie-breaker on centre of vital interests. The certificate is necessary, not sufficient. For where the holding sits afterwards, see our note on the UAE holding company in 2026.

Citation capsule: A French founder stays resident if any article 4 B test applies: home, principal stay, professional activity or centre of economic interests (Legifrance, 1990). The UAE grants domestic residency at 90 or 183 days, but a treaty residency certificate generally needs 183 days of presence, and the Article 4 tie-breaker still decides a dual-residence claim.

Do you pay the French exit tax on your SAS or SARL shares?

You may. The exit tax of article 167 bis applies on transfer of fiscal domicile out of France to unrealised gains on substantial shareholdings, and it triggers where the global value of your holdings exceeds EUR 800,000, or where they represent at least 50% of a company's profits (Legifrance, 2026). A further condition: you must have been a French fiscal resident for at least six of the ten years before departure.

The EUR 800,000 or 50%-of-profits threshold

The threshold catches more founders than expected. A successful SAS or SARL stake can clear EUR 800,000 in latent gain on its own, and the alternative 50%-of-profits limb pulls in owner-managers of smaller but profitable companies. The tax is computed on the unrealised gain as if you had sold on the day before departure. It is real, even though you have sold nothing.

Deferral, the 12.8% guarantee and the relief clock

A move to the UAE does not get the automatic EU deferral. For a non-EU destination, the sursis de paiement is granted on request, against the appointment of a fiscal representative in France and a guarantee equal to 12.8% of the total gains (Legifrance, 2026). The deferred tax is then extinguished, degreve, after you hold the shares for two years post-departure, or five years where the global value exceeds EUR 2.57 million. Selling inside that window crystallises the tax. The filing is due with the departure-year return, and we have seen founders lose the deferral simply by missing that declaration, not by failing the substance test. For the wider cost picture, see our cost to set up a company in Dubai in 2026.

Citation capsule: The exit tax of article 167 bis taxes unrealised share gains on departure where holdings exceed EUR 800,000 or 50% of company profits, after six of the prior ten years as a French resident (Legifrance, 2026). A UAE move needs a fiscal representative and a guarantee of 12.8% of the gains; relief follows after two years, or five above EUR 2.57 million.

Will France tax your Dubai company's profits under CFC rules?

It can, through two separate regimes. Article 209 B taxes a French corporate-tax-liable company on the profits of a foreign entity it controls by more than 50%, where that entity sits under a privileged tax regime; the 50% drops to 5% where more than half is held by linked French entities (Deloitte Societe d'Avocats, 2026). Article 123 bis does the parallel job for individuals.

The 40%-lower "privileged regime" gate

A foreign regime is "privileged" under article 238 A when its tax is at least 40% lower than the French tax otherwise due. UAE corporate tax at 9% against France's 25% clears that gate as a general rule (BOFiP, 2026). So the privileged-regime test is usually met, which means it is not the test that saves you. The real defence sits in the safeguard clause, and that turns on substance. The exact application depends on your entity's effective rate, so confirm it before relying on it.

Article 123 bis for individuals: the 10% trap

For individuals, article 123 bis bites at a 10% holding in a foreign entity that is both privileged-taxed and principally financial in its assets, attributing profits pro-rata with the base increased by 25% (Legifrance, 2026). The "principally financial" condition is the swing factor. A passive UAE holding company stuffed with portfolio assets is squarely in range; a genuine operating company with staff, clients and trading income is far less exposed. The Conseil d'Etat refined that test on 12 November 2025. For a passive structure, our note on the UAE holding company in 2026 sets out the design points.

Citation capsule: France can attribute a Dubai company's profits under article 209 B (corporate control over 50%) or article 123 bis (individuals from 10%, base raised 25%) where the entity is privileged-taxed and, for individuals, principally financial (Legifrance; Deloitte, 2026). UAE 9% against French 25% clears the 40%-lower privileged-regime test, so genuine substance is the defence.
