French expat returning from the UAE: structuring the second leg

Returning to France: the often-overlooked second leg

A return to France after a UAE stint is the second pivotal moment of an expatriation. It is often less prepared than the departure — yet it carries fiscal consequences that can be as material. This page outlines the framework for French expatriates contemplating a return, with particular attention to the interaction between French residency rules, the UAE-issued Tax Residency Certificate, and the deferred exit tax that may still be in force.

French residency on return

Article 4 B of the CGI sets the French residency tests: foyer or principal place of stay, professional activity in France on a non-accessory basis, and centre of economic interests. Any one of these tests, applied to facts on the ground after the return, can re-establish French residency. The 2025 finance act explicitly codified the conventional override: a person meeting the French criteria may nevertheless be treated as non-resident if a tax treaty allocates residence to the other State.

The deferred exit tax: relief on return

For an individual whose departure triggered the French exit tax of article 167 bis CGI with the deferral on option (article 167 bis, V), the return to France before the expiry of the 2-year period — or 5 years where the aggregate value of the securities exceeded €2.57m at departure — is a major event. Under article 167 bis, VII-2 of the CGI, the return to France triggers an automatic relief (dégrèvement d'office) of the income tax and social levies assessed on the latent gains (or their refund if they were paid on departure), provided the securities are still held in the taxpayer's estate at the date of return. The fiction of disposal is undone; the deferred tax disappears.

Re-establishing French residency: the calendar

The date of return that triggers the recovery of French residency is determined by the application of article 4 B of the CGI; for the year of arrival, only income arising from the date the domicile is established in France is brought into the French resident tax base (article 166 CGI). In practice:

• If the foyer is re-established in France, residency runs from that date.
• If the professional activity is taken up in France, residency runs from the resumption date.
• If the centre of economic interests is moved, residency runs from the corresponding event.

The transition may give rise to a "split year" where the taxpayer files a French tax return covering only the post-return period. The pre-return period is treated as non-resident, with French source income taxed under the non-resident rules.

The impatriate regime — article 155 B CGI

A French expatriate returning from the UAE may benefit from the impatriate regime of article 155 B CGI — but only under strict conditions. The regime is reserved for employees and certain corporate officers called to France by a foreign company to work in a related French company, or recruited directly from abroad by a company established in France. A person who returns to France on their own initiative and then looks for a job locally is excluded (BOI-RSA-GEO-40-10-10). Key features:

• Exemption of the impatriation premium for its actual amount or, on election, for a flat amount deemed equal to 30% of total net remuneration (article 155 B, I-1 CGI); a global cap applies — either the total exemption (premium + foreign-workday pay) is limited to 50% of total remuneration, or the foreign-workday exemption alone is limited to 20% of taxable remuneration.
• Exemption of 50% of certain foreign-source passive income — investment income, certain IP income, and capital gains on securities — provided the payer (or depositary) is established in a State that has concluded with France a tax treaty containing an administrative assistance clause (article 155 B, II CGI). The UAE qualifies, the 1989 convention containing such a clause in its article 21 A.
• Eligibility: not having been a French tax resident during the 5 calendar years preceding the year of taking up the position, and becoming French tax resident upon taking it up (article 4 B, 1-a and b CGI).
• Duration: until 31 December of the 8th year following the taking up of the position (for positions taken up since 6 July 2016 — Finance Act for 2017).

French situated assets: the post-return regime

Real estate held in France during the UAE stint is taxable as follows on return:

• Rental income: integrated into the French global income with progressive scale and prélèvements sociaux 18.6% (2026 LFSS).
• Real estate capital gains: the residency at the date of disposal determines the regime. A disposal post-return follows the normal resident regime (length-of-holding allowances, principal residence exemption where applicable).
• IFI (wealth tax on real estate): resumes on French and worldwide real estate.

UAE assets: the integration into the French tax base

UAE situated assets are integrated into the French tax base on return:

• Bank accounts: declared on form 3916 (article 1649 A CGI) every year.
• Insurance contracts: declared on form 3916-bis (article 1649 AA CGI).
• Trust interests: declared on form TRUST (article 1649 AB CGI).
• UAE company holdings: distributions and gains are taxed at the shareholder's level under French rules; UAE Corporate Tax paid by the entity gives rise to no personal foreign tax credit. Where the UAE entity is mainly financial and enjoys a privileged tax regime, the CFC rule for individuals of article 123 bis CGI must be checked (10% holding threshold).
• UAE source dividends: taxed under the PFU (12.8% IR + 18.6% social levies = 31.4% since the 2026 social security finance act); under article 8 of the 1989 treaty (as amended in 1993), dividends are taxable only in the beneficiary's State of residence — i.e. France after the return.

Practical roadmap for the return

1. Audit at T-12 months: residency analysis, deferred exit tax status, IFI exposure, impatriate eligibility.
2. Anticipate French employer onboarding, payroll structure, and impatriation premium clauses.
3. Document the UAE departure (TRC of the year of return, Cabinet Decision 85/2022 evidence of past residency).
4. Notify the French tax authorities of the return and of the new address without delay (no specific statutory deadline, but prompt notification conditions the release of exit tax guarantees and the correct split-year assessment).
5. Terminate the fiscal representative appointment and request the release of guarantees.
6. File the year of return tax return with split-year treatment.
7. If applicable, file the impatriate regime election in the first French tax return.
8. Update declarations on French and foreign accounts (3916, 3916-bis, TRUST).
