How to leave France tax residency, legally

France doesn’t catch you on the 183-day rule. Spain does; Germany does; the UK does. France uses the foyer test. If your household — your family’s habitual home — is in France, you’re a French tax resident regardless of how many days you spent in Paris, Bangkok or Buenos Aires that year. That single structural difference makes the French exit harder than the others, and it explains why founders who’ve planned their move perfectly on paper are still paying French tax a year after boarding the plane.

This is the version we run with members going France to Thailand or Paraguay. It assumes a clean foyer situation and a complete professional deregistration — the two places where French exits slip.

The residency test that isn’t the 183-day rule

Article 4 B of the Code Général des Impôts (CGI) makes you a French tax resident if any one of three conditions is met:

1. Foyer — your habitual household, meaning where your family (spouse, dependent children) lives. Not where you live. Where they live.
2. Principal place of professional activity — if the majority of your professional work is carried out in France.
3. Centre of economic interests — where the main body of your assets, investments and income-generating activities is concentrated.

The difference from Germany and Spain: any single condition is sufficient. You can spend 60 days in France, have no apartment, have a Spanish bank account — and if your spouse and children are in a Paris flat you pay the rent on, France treats you as resident. Full French income tax. On worldwide income.

The practical consequence: founders who move alone while their family stays in France have not exited French tax residency. They have created a compliance liability in two jurisdictions simultaneously. This is the first question we ask on every diagnosis call: what is the foyer situation?

Three professional tracks

French professional deregistration depends on your legal structure. Each has a different sequence and different timing.

Auto-entrepreneur (micro-entrepreneur): File your radiation electronically via autoentrepreneur.urssaf.fr. The process takes under ten minutes. Your SIRET deactivates automatically within two weeks. File final CA (Chiffre d’Affaires) declarations for the quarter of departure — including partial-month revenue. Close the CFE (Cotisation Foncière des Entreprises) separately with your local commune’s revenue service. The professional bank account closes once the final CA settlement clears.

Profession libérale: URSSAF notification closes mandatory health and pension contributions. Depending on your profession, you may be registered with CARPIMKO, CIPAV, CNAVPL or another profession-specific pension fund — each requires a separate departure notification. CSG/CRDS on French-source income continues to apply even as a non-resident.

SAS or SARL: The company does not close because you leave France. It remains a French legal entity, taxed under Impôt sur les Sociétés (IS), regardless of where the shareholders live. As a non-resident shareholder, dividends you receive are subject to French withholding tax. Under domestic law: 30% flat (12.8% IR + 17.2% social charges). Under a tax treaty: often lower. France and Thailand have a comprehensive double-tax treaty in force (signed 27 December 1974) — a Thai-based shareholder can claim dividend relief under Article 10 instead of the flat 30% domestic rate. For founders with meaningful SAS equity, the pre-departure structuring question is often the most consequential part of the exit.

The exit tax (Article 167 bis CGI)

France’s exit tax fires when two conditions are met simultaneously:

Condition 1 — Residency duration: You’ve been a French tax resident for at least 6 of the last 10 tax years before the year of departure.

Condition 2 — Asset threshold: You hold financial securities worth more than €800,000 in total — shares, partnership rights, convertible bonds, stock options with latent gains — OR securities representing more than 50% of the profits of one company.

If both conditions apply, France taxes the latent capital gain as if you sold everything on the day before you left. The rate: 30% flat (12.8% prélèvement forfaitaire unique + 17.2% prélèvements sociaux). You can elect the progressive income-tax scale instead if that produces a lower bill.

Form 2074-ETD (Déclaration de transfert de domicile fiscal) must accompany your final resident tax return. It documents the event and triggers the assessment. For a non-EU move, attach the bank guarantee documentation when filing.

If your securities are under €800,000 or you’ve been French resident for fewer than 6 of the last 10 years, Article 167 bis doesn’t apply. Most early-stage founders are out of scope; established operators with material equity positions need to model it before the departure date is set.

The garantie bancaire — what nobody plans for

For Thailand or Paraguay exits, the exit-tax deferral requires a bank guarantee from your French bank equal to the exit-tax liability. The bank holds this guarantee until you sell the underlying securities, at which point you pay the deferred tax from the sale proceeds.

Getting the guarantee takes 2–4 weeks depending on your bank. Some branches are unfamiliar with the process and require escalation. We have seen members miss their planned departure date because the bank wasn’t ready. The fix: start the guarantee process six weeks before departure, not two.

The departure sequence

The French exit doesn’t have a single trigger document. It’s a sequence:

1. Notify your SIP (Service des Impôts des Particuliers) of your departure — a letter with your effective date and destination address. Keep proof of posting.
2. Professional deregistration — URSSAF, CPAM, pension funds, CFE. Do this before departure or within 30 days after.
3. Exit-tax assessment and guarantee — if Article 167 bis applies, arrange the garantie bancaire. Prepare Form 2074-ETD.
4. Destination paperwork — DTV application or Paraguay cédula, bank account, real lease in your name.
5. Departure.
6. Final Déclaration de revenus (Form 2042 + 2042 C pro if self-employed) for the departure year. Standard deadline: May/June of the following year. If you depart after October 31, a 60-day accelerated deadline from departure applies.
7. Year +1: Thai Revenue Department or Paraguayan SET tax-residency certificate.

A 16-week timeline

Most CERØ members run roughly this calendar from engagement to clean French exit:

• Week 1. Diagnosis call. We map the foyer, professional structure, Article 167 bis exposure and the timing.
• Weeks 2–5. Professional deregistration. URSSAF, CPAM, pension funds, CFE — tracked weekly.
• Weeks 4–8. Exit-tax assessment. Garantie bancaire arranged with your bank if needed. Form 2074-ETD prepared.
• Weeks 6–10. Destination visa. DTV file or cédula application. Thai or Paraguayan bank account. Real lease signed.
• Weeks 10–12. Departure. SIP notification filed.
• Weeks 12–18. First days on the ground. Local registrations. Tax-residency certificate clock starts.
• Year-end. Final Déclaration de revenus (2042 + 2074-ETD). No residency, no full-year IRPP.
• Year +1. Thai or Paraguayan residency certificate. The document the DGFIP accepts.

What the DGFIP actually checks

The Direction Générale des Finances Publiques doesn’t just take your word for departure. In a France exit under examination, they check substantive relocation:

• Whether the foyer actually moved — did the family leave France?
• Whether professional activity was fully ceased in France.
• Whether you hold a genuine, signed lease at the destination.
• Whether a foreign tax-residency certificate was obtained in the year following departure.
• Whether French-source income after departure is correctly treated as non-resident (withholding at source, not full resident filing).

The weak file: founder left for Bangkok, spouse stayed in Paris, car registered in France, income still paid to a French account. The DGFIP treats them as French-resident for years after departure.

The strong file: foyer moved. URSSAF closed. Bangkok lease signed. Thai certificate in year +1. No French-registered assets maintained. The DGFIP has nothing to examine.

The piece nobody tells you

France and Thailand have a comprehensive double taxation treaty in force (signed 27 December 1974, updated via the BEPS MLI). It provides a treaty mechanism to resolve potential overlap in the transition year. Once genuinely non-resident — foyer resolved, professional deregistration complete, Thai certificate obtained — France has no basis to tax your Bangkok income. But the first twelve months require documentation, because it’s when most examinations focus.

The SAS dividend situation is the other piece that surprises founders. A French SAS paying dividends to a Thai-resident shareholder can claim treaty relief under Article 10 rather than suffering the flat 30% domestic withholding with no relief. Even so, founders who planned to draw income from their French company while living in Bangkok often end up paying more than they expected — just structured differently. Pre-departure restructuring changes this; post-departure restructuring from Thailand is harder.
