How to Leave the French Tax System: Exit Tax and ISF Considerations

France combines aggressive tax rates with specific exit provisions that apply to departing residents with substantial shareholdings or investment portfolios. While the exit tax is not as broadly applied as those in Germany, Australia, or Canada, its interaction with France's complex residency rules, social security charges, and wealth-related taxes creates a departure that requires careful orchestration.

French Tax Residency: The Four Alternative Bases

Under Article 4B of the Code General des Impots (CGI), an individual is considered French tax resident if any one of four conditions is met:

1. Foyer (Home) -- Your principal family home is in France. This test is satisfied if your spouse and children live in France, even if you spend the majority of your time abroad.

2. Lieu de sejour principal (Principal place of abode) -- You spend more than 183 days in France during the calendar year.

3. Activite professionnelle (Professional activity) -- You carry on a professional activity in France (employment or self-employment), unless that activity is ancillary.

4. Centre des interets economiques (Centre of economic interests) -- Your principal investments, the headquarters of your businesses, or the place from which you manage your assets is in France.

Any single test is sufficient. The breadth of these tests, particularly the foyer and centre of economic interests tests, means that merely reducing days in France is insufficient. The family and economic connections must also be severed.

The French Exit Tax: Article 167 bis CGI

The French exit tax (impot sur les plus-values latentes) applies when a French tax resident who meets specific thresholds ceases French tax residency.

Triggering Conditions

The exit tax applies if, on the date of departure, the individual:

• Holds securities, rights, or interests with an aggregate unrealised gain exceeding EUR 800,000, OR
• Holds directly or through a related person at least 50% of the droits sociaux (voting rights or financial rights) in a company

The Charge

• The exit tax is calculated on the unrealised gain at the date of departure
• Rate: 30% flat tax (prelevement forfaitaire unique, or PFU), composed of 12.8% income tax and 17.2% social contributions (prelevements sociaux)
• Alternatively, the individual can opt for progressive income tax rates (up to 45%) plus social contributions, if this is more favourable

Deferral Mechanism

Moves to EU/EEA states:

• Automatic deferral without any security requirement
• The individual must declare the exit tax on the departure tax return and file annual monitoring returns (declaration de suivi)
• The deferred tax is discharged entirely if the securities have not been disposed of after 5 years

Moves to non-EU/non-EEA states with a mutual assistance agreement (convention d'assistance administrative):

• Deferral is available but requires filing the declaration de suivi annually
• The 5-year discharge also applies

Moves to states without a mutual assistance agreement:

• The individual must appoint a tax representative in France and may be required to provide security
• The 5-year discharge still applies

The 5-Year Rule

This is the critical planning element. If the departing individual:

• Retains the securities for at least 5 years after departure
• Has not returned to France during that period

The exit tax is completely written off. This makes France's exit tax one of the most manageable in Europe, provided the individual can avoid disposing of the securities for five years.

Social Security Obligations

France's social security system (securite sociale) is linked to residency and professional activity. On ceasing French residency:

• Affiliation to the French social security system ends
• Continued access to the French healthcare system is available for a transitional period (typically up to 12 months after departure)
• CSG (Contribution Sociale Generalisee) and CRDS (Contribution au Remboursement de la Dette Sociale) no longer apply to foreign-source income after departure
• French-source rental income remains subject to prelevements sociaux at 17.2% for non-EU/EEA residents (reduced rates or exemptions apply for EU/EEA residents under the de Ruyter jurisprudence and subsequent legislation)

Impot sur la Fortune Immobiliere (IFI)

France replaced the wealth tax (ISF) with IFI in 2018. IFI applies only to real estate assets.

• French tax residents are subject to IFI on worldwide real estate assets
• Non-residents are subject to IFI only on French real estate
• The threshold is EUR 1,300,000 in net real estate assets
• Rates range from 0.5% to 1.5%

On departure, IFI liability shifts from worldwide real estate to French real estate only. For individuals with significant foreign real estate holdings, this creates an immediate saving.

Ongoing French Tax Obligations After Departure

Non-residents remain subject to French tax on:

• French-source employment income
• French rental income (subject to a minimum effective rate of 20%, or 30% for income exceeding EUR 27,478)
• Capital gains on French real property (19% plus 17.2% social contributions for non-EU residents, 7.5% surtax on gains exceeding EUR 50,000)
• Dividends from French companies (12.8% withholding, reduced under applicable DTA)
• Interest from French sources (12.8% withholding, reduced under applicable DTA)

Planning Strategies for Departure

Pre-Departure Dividend Distributions

Distributing retained earnings from French or foreign companies before departure reduces the fair market value of shareholdings, potentially bringing the unrealised gain below the EUR 800,000 threshold.

Donation or Gift Before Departure

Gifting shares to family members before departure can reduce the individual's holding below the 50% threshold. However, French gift tax (droits de donation) applies at progressive rates up to 45% for direct-line gifts (with an allowance of EUR 100,000 per parent per child every 15 years).

Intermediate EU Step

For individuals moving to non-EU jurisdictions, establishing genuine residency in an EU state first ensures automatic deferral without security. After 5 years, the exit tax is discharged regardless of the final destination.

Timing of Departure

French tax residency is assessed on a calendar-year basis. Departing early in the year minimises French-source income for that year. However, the foyer test can maintain residency for the entire year if the family remains in France.

Restructuring French Real Estate

Given that IFI continues to apply to French real estate held by non-residents, and that French property gains are taxed at high effective rates for non-residents, consider whether French real estate should be sold before or restructured before departure.

The Departure Process

1. Notify the Service des Impots des Particuliers (SIP) of the change of address and residency status
2. File the departure-year tax return (Form 2042), indicating the date of departure and reporting all income to that date
3. File the exit tax declaration (Form 2074-ETD) reporting unrealised gains on qualifying securities
4. File the IFI return (Form 2042-IFI) for real estate assets
5. Arrange continued filing for French-source income in subsequent years (Form 2042-NR for non-residents)
6. Appoint a tax representative if required (for non-EU/EEA departures in certain cases)

Key Takeaways

• France's exit tax applies to unrealised gains exceeding EUR 800,000 or shareholdings of 50%+ on departure.
• The tax is deferred automatically for EU moves and discharged entirely after 5 years if the securities are not sold.
• The 5-year discharge rule makes France's exit tax significantly more manageable than Germany's or Australia's.
• France's four alternative residency tests mean that merely reducing days is insufficient -- family and economic ties must also be severed.
• IFI continues to apply to French real estate held by non-residents.
• Pre-departure planning should focus on reducing share values through distributions and timing the departure to minimise the overall tax cost.
