Moving to France after several years in Switzerland profoundly alters the applicable tax system. Unlike leaving for Switzerland, which triggers an exit tax on unrealised capital gains on significant securities, returning to France does not trigger any specific federal taxation on the Swiss side. On the other hand, several technical issues arise simultaneously: withdrawal from the 2ᵉ pillar, articulation with current cantonal returns, eligibility for the impatriate regime, treatment of assets held during expatriation. Here are the essential points to prepare for a smooth, tax-optimized return.
Switzerland has no exit tax in the French sense
First point to remember: Switzerland does not have a system equivalent to article 167 bis of the French CGI. The departure of a Swiss resident to France does not trigger federal taxation on unrealized capital gains on privately held securities. This federal neutrality constitutes a strategic advantage: securities portfolios can be held or sold according to economic opportunity, without any specific tax constraints linked to the transfer of residence.
There are, however, a few exceptions at cantonal level:
- the latent business reserves of self-employed persons working in Switzerland (clientele, business goodwill, fixed assets) may be taxed on cessation of activity or transfer outside the canton, in accordance with cantonal rules;
- unrealized foreign exchange gains on certain business accounts may be subject to special treatment.
For an executive, director or annuitant holding classic private assets (securities, real estate, bank accounts), no exit tax is due on the Swiss side at the time of departure.
Withdrawal from the 2ᵉ pillar: the key tax operation on departure
The most tangible tax issue involved in returning to France concerns the Swiss 2ᵉ pillar (LPP), i.e. the compulsory occupational pension built up during the period of salaried employment in Switzerland.
When you leave Switzerland permanently, you have several options:
- Lump-sum withdrawal: pension capital can be withdrawn in full, provided that the departure is definitive and outside the European Union for the compulsory portion (France meets the condition for the supplementary portion, but not for the compulsory portion, which remains blocked until retirement or transfer to a vested benefits institution).
- Maintained in a vested benefits account: the credit remains blocked in a Swiss vested benefits foundation until retirement or an event permitting withdrawal (purchase of principal residence, subsequent return to Switzerland, etc.).
- Transfer to an equivalent scheme in the destination country: few countries have a strictly equivalent mechanism for direct transfer.
The tax treatment of withdrawals varies from canton to canton and from country to country. The canton of last residence (or the canton where the vested benefits foundation is headquartered) levies withholding tax on the capital, at a preferential rate compared with current income. This deduction is definitive on the Swiss side.
On the French side, withdrawals from the Swiss 2ᵉ pillar are in principle exempt from income tax on lump-sum retirement benefits, provided that the corresponding contributions have been paid on a compulsory basis and that no tax deduction has been made in France on these contributions. However, this exemption presupposes solid evidence of the compulsory nature of the contributions and the absence of any double tax advantage. Doctrine and case law are evolving on this point, and a specific analysis is recommended before each withdrawal.
Double taxation agreement: the role of the Franco-Swiss treaty
The Franco-Swiss tax treaty of September 9, 1966, amended by the 2014 rider, provides a framework for the allocation of taxing rights between the two states. For the return from Switzerland to France, several articles are of particular interest:
- income from employment received prior to departure remains taxable in Switzerland (place of employment);
- Pensions are treated differently depending on whether they come from public or private sources;
- capital gains on real estate located in Switzerland remain taxable in Switzerland;
- dividends from a Swiss company are subject to a withholding tax in Switzerland (35% for unlisted companies, conventional rate of 15% for French-resident individuals), with an imputation mechanism on the French side.
Coordination of declarations on return requires production of a certificate of French tax residence and compliance with bilateral forms (form 5000, 5001 for dividends; French forms 2042 and 2047 for Swiss-source income received in the year of return).
The impatriate regime: eligibility on return from Switzerland
Returning to France after several years spent in Switzerland may entitle you to the impatriate regime set out in article 155 B of the French General Tax Code. Three essential conditions must be met:
- Non-residence for French tax purposes for five calendar years prior to return. An effective expatriation of 5 years or more in Switzerland fully satisfies this condition, provided that French tax residence has not been maintained during this period.
- Assumption of duties in France under an employment contract. The return must be part of a recruitment by a French company or an intra-group secondment to a French entity.
- Tax domicile in France from the date of appointment.
The scheme gives entitlement, for eight years, to several partial exemptions: impatriation bonus, fraction of remuneration linked to foreign activity, passive income from foreign sources, temporary IFI exemption on real estate located abroad. For full details, see our complete guide to the impatriate regime.
The return from Switzerland is of particular interest: passive income from Swiss sources (dividends, interest, any capital gains from Swiss sources) can benefit from the 50% partial exemption, provided that it is not received in France and that Switzerland meets the condition of an administrative assistance agreement (which is the case).
Assets held in Switzerland at the time of return
The repatriation of tax residence to France raises the question of what happens to assets held in Switzerland during expatriation. Several categories need to be examined:
- Swiss bank accounts: may be kept, but must be declared in France using form 3916 (bank accounts held abroad) each year. Failure to do so is punishable by a fine.
- Securities portfolios held in Switzerland: simply holding them remains unrestricted, but income received (dividends, interest) must be declared in France and taxed according to French law, subject to the application of the impatriate regime and tax treaties.
- Real estate in Switzerland: rental income and any capital gains on disposal remain taxable in Switzerland (article 6 and article 15 of the Franco-Swiss treaty). They may benefit from temporary IFI exemption during the period of application of the impatriate regime.
- Swiss life insurance policies: these come under a special regime, with specific rules for partial and total surrenders, as well as for transfer. A case-by-case analysis is required.
- Unwithdrawn pension assets: 2ᵉ pillar in vested benefits account, blocked 3ᵉ pillar A, etc. Their status and tax treatment at the time of subsequent withdrawal merit a specific review.
Case study: returning to Paris after 8 years in Geneva
Mrs B., a marketing manager who had been based in Geneva for 8 years, was appointed Managing Director of a French subsidiary of her group. Her annual remuneration rises from 280 k€ CHF to 320 k€ EUR, including 70 k€ identified as an impatriation bonus in her contract. In Switzerland, she has an LPP credit balance of 450 k€ CHF, a securities account of 600 k€ CHF, and an apartment in Geneva which she keeps and rents out.
Strategy deployed :
- Impatriate regime: meets all three conditions. The scheme applies for 8 years from the date of taking up the French post. Exemption from the 70 k€/year bonus, partial exemption from Swiss passive income, IFI exemption on the Geneva apartment for 5 years.
- 2ᵉ pillar: option for partial withdrawal (over-mandatory portion), balance maintained in a Swiss vested benefits account until retirement. Withholding tax in Geneva on the withdrawal, exemption on the French side provided the compulsory nature of the contributions is documented.
- Geneva securities account: retained, annual declaration 3916, dividends included in French declaration with deduction of Swiss withholding tax.
- Geneva apartment: rental income taxed in Switzerland, also declared in France for calculation of effective rate, temporary IFI exemption.
Common mistakes to avoid on the return journey
- Underestimating the 5-year requirement for impatriate status. A partial return to France during the expatriation period, even if temporary, may render you ineligible.
- Receive passive income from Swiss sources in France, which excludes it from partial exemption under the impatriate regime.
- Failure to declare Swiss bank accounts (form 3916), Swiss life insurance policies (form 3916 bis) and non-withdrawn pension assets.
- Withdrawing the 2ᵉ pillar without preparation on the French side: a massive withdrawal in year 1 of the return may generate questions from the administration about the nature of the benefit and its eligibility for exemption.
- Poor coordination of bilateral declarations in the year of return: Switzerland requires a partial declaration for resident months; France requires a declaration for the whole year, mentioning Swiss-source income received prior to return.
Indicative timetable for a return trip Switzerland → France
- 6 to 12 months before return: pre-return tax audit, impatriate regime simulation, choice of 2ᵉ pillar withdrawal options, anticipation of potential asset disposals.
- 3 to 6 months before: finalization of the French employment contract with explicit breakdown of the impatriation premium, arrangements with the LPP foundation for withdrawal, choice of reference canton.
- Month of return: effective transfer of residence (lease, schooling, updating of bank accounts), declaration of departure to the Swiss cantonal authorities.
- Year of return: French tax return for the whole year, including the portion of Swiss-source income received prior to return. Swiss return for months of residence.
- The following year: first full French tax return under the impatriate regime. Introduction of routine annual tax returns (3916, passive income, IFI).
