Moving from France to St. Kitts & Nevis can take a top combined burden of roughly 49% on labour income, 30% on portfolio gains and dividends under the Prélèvement Forfaitaire Unique, IFI on net real estate above €1.3M, and inheritance tax up to 60% outside the direct line, and replace it with a clean 0% across personal income, capital gains, dividends, gifts, and inheritance. The Federation runs the world’s oldest Citizenship by Investment programme — uninterrupted since 1984 — and currently hands a full passport for a US$250,000 contribution to the Sustainable Island State Contribution (SISC) fund or a US$325,000+ approved real-estate purchase, in 4–6 months on the standard track and faster under the Accelerated Application Process. Two structural facts make this corridor genuinely different from a France-to-Cyprus or France-to-Portugal move, and they dictate the entire planning sequence: (1) St. Kitts & Nevis is non-EU/EEA, so article 167 bis CGI exit tax runs without automatic interest-free deferral and almost always requires a financial guarantee for any deferred payment; and (2) there is no comprehensive double-tax convention in force between France and the Federation — only a Tax Information Exchange Agreement (TIEA, signed 2009, in force since 2010) supplemented by CRS automatic exchange. The good news is that, unlike Vanuatu or Panama, St. Kitts & Nevis is not currently on France’s liste des États et territoires non coopératifs under article 238-0 A CGI, so the punitive 75% withholding under article 244 bis B does not bite. The bad news is that CBI alone never makes you SKN tax-resident, and without a treaty tie-breaker, the DGFiP audit risk is concentrated entirely on whether you have severed foyer, séjour principal, activité, and intérêts économiques under article 4 B CGI.
The Tax Delta at a Glance
| France (current) | St. Kitts & Nevis (after move) | |
|---|---|---|
| Personal income tax | 0% to 45% progressive (barème IR) | 0% — no personal income tax statute |
| Contribution exceptionnelle (CEHR) | 3% to 4% above €250K / €500K of revenu fiscal de référence | None |
| Capital gains / dividends | 30% PFU (12.8% IR + 17.2% CSG/CRDS), +CEHR at top | 0% on foreign gains and dividends |
| Wealth tax (real estate – IFI) | 0.5% to 1.5% on French + worldwide property above €1.3M | 0% — no wealth tax; IFI continues on retained French real estate post-departure |
| Inheritance / gift | 5%–60% (45% top direct line, 60% non-relatives) | 0% — no inheritance, estate or gift tax |
| Worldwide vs territorial | Worldwide for residents under article 4 A CGI | No income tax at all — moot |
| Corporate tax | 25% IS standard | 33% on Federation-source profits; 0% on properly-structured offshore activity |
| Effective rate (typical entrepreneur) | ~49% on salary, 30% on dividends/CGT, up to 64% on inheritance | 0% personally, in full |
The right-hand column only crystallises if both legs close: a clean cessation of French residence under article 4 B CGI, and a credible build-out of substance somewhere — in SKN itself or, far more commonly, in a paired residency hub like the UAE or Anguilla where the Federation passport is used for mobility rather than for day-counting. Until then, the Direction Générale des Finances Publiques (DGFiP) continues to tax you on worldwide income at French rates.
Step-by-Step Move
Step 1: Confirm you can legally cease French tax residency under article 4 B CGI
French tax residency is governed by article 4 B of the Code général des impôts, which lists four alternative tests — meeting any one keeps you French-resident on worldwide income:
- Foyer — the habitual home of you and your family (spouse and minor children). The Conseil d’État treats family location as decisive whenever the family does not move with the taxpayer.
- Lieu de séjour principal — the jurisdiction where you spend the most days, applied when the foyer test is inconclusive (typically single people).
- Activité professionnelle principale — where your principal professional activity is carried on.
- Centre des intérêts économiques — the location of your main investments, the seat of your business management, and your principal source of income.
The DGFiP applies a faisceau d’indices — there is no day-count safe harbour. The foyer trap is acute on this corridor because the SKN CBI imposes zero physical-presence requirement: you can be sworn in remotely, never visit the Federation, and continue to live in Paris. A taxpayer with an SKN passport, a 16ème pied-à-terre “kept for visits”, and a circulating life across Dubai, London and Geneva is, on those facts alone, almost certainly still French-resident under foyer or intérêts économiques. The CBI bought a passport, not a tax outcome.
Step 2: Plan around France’s exit tax (article 167 bis CGI)
The exit tax under article 167 bis CGI is the single largest cash-flow risk on this corridor. It catches individuals who have been French tax-resident for at least six of the last ten years and, on the day of departure, hold either (a) a participation worth more than €800,000, or (b) at least 50% of the corporate rights of any company. It crystallises a deemed disposal of those holdings at fair market value the day before departure, with a default tax rate of 30% PFU (12.8% income tax + 17.2% social charges) plus the Contribution exceptionnelle sur les hauts revenus of 3–4% at higher revenu fiscal de référence bands.
For an EU/EEA destination the deferral (sursis de paiement) is automatic and interest-free, with no guarantee required. St. Kitts & Nevis is non-EU/EEA, so deferral is available on request but is conditional on posting an acceptable financial guarantee — typically a bank guarantee or pledged securities — to the DGFiP, and the procedural friction is real (form 2074-ETD with all annexes, notification to the Service des Impôts des Particuliers Non-Résidents in Noisy-le-Grand, and renewal of the guarantee). The deferred tax is définitivement dégrevé (permanently extinguished) if you have not actually disposed of the relevant securities fifteen years after departure for capital gains tax purposes; CSG/CRDS social charges follow a parallel but distinct extinguishment timetable, and the interaction with prélèvements sociaux on French-source dividends after departure must be planned separately.
The decisive planning lever is whether to dispose before departure (paying full French CGT now and walking out with a clean basis step-up under SKN’s no-tax regime) or to defer with guarantee (preserving liquidity but accepting fifteen years of compliance and a guarantee cost). For a founder who expects to sell within 2–4 years, deferral is rarely worth the friction; for a long-hold portfolio, deferral with eventual extinguishment is usually the right answer.
Step 3: Establish St. Kitts & Nevis tax residency (and decide whether you actually need to)
The SKN side is mechanically simple but conceptually subtle. Citizenship under the CBI does not equal tax residency — it gives you a passport, the right to live in the Federation, and access to the 0% regime if and when you become tax-resident there. The CBI choices, with current published thresholds:
- SISC contribution route — US$250,000 minimum non-refundable contribution to the Sustainable Island State Contribution fund (single applicant; family-of-four pricing follows a published scale)
- Approved Real Estate route — US$325,000+ in an approved condominium share or US$600,000+ stand-alone property, with a 7-year minimum hold
- Public Benefit Option — typically US$250,000+ deployed through pre-approved Federation infrastructure projects
Add roughly US$25,000 government processing fee, US$10,000+ due-diligence fee, and US$15,000–US$40,000 for the Authorised Agent. The standard track runs 4–6 months; the Accelerated Application Process can compress this materially. See the St. Kitts & Nevis country page for the full breakdown.
To convert citizenship into provable SKN tax residency you must physically relocate, pass the 183-day rule locally, register with the Inland Revenue Department, and document a centre-of-vital-interests on the islands. The vast majority of French CBI clients do not go this route — they pair the SKN passport with day-count residency in the UAE (90/183 day visa under Cabinet Decision 85/2022) or with Anguilla’s High Value Resident certified-tax-residency programme, and use the SKN nationality for mobility, banking, and Plan B.
Step 4: Document the break and the new tie
You will have to prove the break in two ways: substantive facts and paper. Substantively, dismantle the French foyer (rent or sell the family home, move the spouse and children, transfer school enrolment), redirect the séjour principal (passport stamps, lease, utilities, medical registration in the new jurisdiction), and unwind the intérêts économiques (managing-director resignations from French operating companies where possible, repatriation of investment accounts, closure or conversion of résidence principale status). Cross-border CB/credit-card spend and mobile-phone connection logs are routinely subpoenaed in contrôle fiscal and can decide cases.
On paper: file form 2042 for the year of departure with the départ à l’étranger indicator and provide the destination address; file form 2074-ETD for the article 167 bis exit-tax computation; deregister from the taxe d’habitation sur la résidence principale if applicable, and notify all French banks and brokers of non-resident status to update tax-treatment on French-source income. Because there is no France–SKN double tax treaty there is no treaty tie-breaker available if the DGFiP later asserts continued residence — you cannot fall back on a “permanent home → centre of vital interests → habitual abode → nationality” cascade as you could with Cyprus or Portugal. Severance must be unambiguous on the facts.
Step 5: First-year compliance in both jurisdictions
In France, file form 2042 for the year of departure splitting the calendar into a resident period (worldwide income) and a non-resident period (French-source income only — French real-estate income, salary for work performed in France, dividends from French sociétés). The Service des Impôts des Particuliers Non-Résidents handles all post-departure filings; do not let your file revert to a domestic Service des Impôts — that signals the DGFiP you may not have left.
In St. Kitts & Nevis there is no annual personal income-tax return — there is no personal income tax statute to file under. If you have actually relocated and elected SKN tax residency you will register with the Inland Revenue Department and, if you operate a Federation-source business, file corporate and VAT returns. CRS automatic exchange runs in both directions: French banks will report your continued French accounts to the DGFiP under your new SKN tax-residency status, and the Federation will exchange information back through the France–SKN TIEA in force since 2010 plus the multilateral Convention on Mutual Administrative Assistance in Tax Matters. The TIEA does not provide treaty relief — it is purely an information-exchange instrument.
Cost & Timeline
| Phase | Cost (€/USD) | Time |
|---|---|---|
| Tax planning + legal review (pre-move) | €15,000–€40,000 | 1–2 months |
| Article 167 bis exit-tax computation, form 2074-ETD, guarantee posting | €5,000–€20,000 + guarantee cost (1–2% of deferred tax/yr) | 1–3 months |
| SKN CBI application (SISC route, single) | ~US$280,000–US$310,000 inclusive of fees | 4–6 months standard, 60–120 days AAP |
| Move + setup (banking, lease, registration in chosen residence hub) | €10,000–€50,000 | 1–2 months |
| First-year dual filing (form 2042 split-year + non-resident return) | €3,000–€8,000 | Annual |
| Total year-1 effective cost (SISC + advisory) | ~US$310,000–US$380,000 | 6–12 months |
Real-estate-route applicants should add the property completion timeline and the 7-year illiquidity. Family-of-four CBI pricing roughly tracks +US$50,000–US$75,000 over the single-applicant baseline, scale-fee dependent.
Treaty Considerations
There is no comprehensive double-tax convention in force between France and St. Kitts & Nevis. The only bilateral instrument is a Tax Information Exchange Agreement signed in 2009 and in force since 2010, supplemented by both jurisdictions’ adherence to the OECD/Council of Europe Multilateral Convention on Mutual Administrative Assistance in Tax Matters and to CRS. The practical implications are sharp:
- No tie-breaker rule — if French-residency tests under article 4 B CGI are met, you are French-resident, and there is no Article 4 OECD-Model cascade to retreat to. This is the opposite of the France–Cyprus or France–Italy position.
- No reduced withholding on French-source dividends, interest, royalties, or pensions paid to an SKN resident — domestic French withholding rates apply (typically 12.8% for dividends paid to individuals, 25% on certain interest streams, with potential exemptions only where domestic French law itself provides them).
- No mutual-agreement procedure (MAP) to resolve disputes between the two tax administrations, which would be the standard remedy under a full treaty.
- The liste ETNC trap is currently inactive — at the date of writing, St. Kitts & Nevis is not listed on France’s liste des États et territoires non coopératifs under article 238-0 A CGI, so the punitive article 244 bis B 75% withholding on French-source securities gains, the article 238 A expense-deduction denial, and the harsher article 209 B CFC regime do not apply by reason of SKN residence alone. This is a real planning advantage versus the Vanuatu corridor and the Panama corridor. The position is monitorable and could change at the next arrêté updating the list.
Common Mistakes
- Buying the passport but never actually leaving France. The single most expensive mistake — the SKN CBI imposes no physical-presence requirement, so it is mechanically possible to continue living in Paris with an SKN passport in the drawer. Foyer + intérêts économiques will keep you French-resident; the DGFiP will tax you accordingly and the CBI capital is a sunk cost.
- Triggering article 167 bis without filing form 2074-ETD or posting the guarantee. Non-EEA destinations require the guarantee to access deferral; missing the deadline crystallises the exit tax as immediately payable.
- Assuming the treaty tie-breaker will save you. It will not — there is no treaty. Severance has to win on the facts.
- Choosing SKN as the actual day-count residence without a substance plan. SKN is a perfectly viable physical residence (and beautiful), but the corporate-tax regime taxes Federation-source business at 33%, and you need to operate a foreign-source structure cleanly to preserve the 0% personal outcome.
- Forgetting Impôt sur la Fortune Immobilière (IFI) on retained French real estate. Even after departure, IFI continues to apply to French-situated property above the €1.3M threshold for non-residents.
FAQ
Will I still have to file in France after moving?
Yes — for the year of departure (split-year form 2042), and for any subsequent year in which you have French-source income (French real-estate rents, French employment income, dividends from French companies, French pension payments). The article 167 bis deferred exit tax also keeps a compliance trail until the 15-year extinguishment.
Can I keep my French bank account, company, or property?
Bank accounts: yes, but tax-treatment changes to non-resident status — notify your bank. French SARL or SAS shareholdings: technically yes, but the article 167 bis exit tax will generally have crystallised on those holdings, and continued management activity from France can re-establish activité professionnelle principale and undo your departure. Property: yes, but IFI continues, French rental income is taxable in France (via form 2042), and a maintained résidence principale is the classic foyer trap.
How long does the full move take?
Realistically 9–14 months end-to-end: 1–2 months pre-move tax planning, 4–6 months for SKN CBI standard track (or compressed under AAP), 1–3 months for exit-tax filing and guarantee posting, 1–2 months for relocation and setup. The Accelerated Application Process can shorten the CBI leg to 60–120 days.
What if the DGFiP disputes my exit?
Without a France–SKN treaty there is no MAP. The dispute proceeds entirely under French domestic procedure: a proposition de rectification from the DGFiP, optional escalation to the Commission départementale des impôts directs et des taxes sur le chiffre d’affaires, and ultimately the administrative courts (Tribunal administratif → Cour administrative d’appel → Conseil d’État). The fact-pattern wins or loses the case — quality of foyer evidence and the absence of French intérêts économiques are decisive.
Is the SKN passport worth it if I’m using UAE or Anguilla as my residency?
Often yes. The Federation passport currently provides visa-free or visa-on-arrival access to 150+ jurisdictions including the Schengen Area, the United Kingdom, Singapore, and Hong Kong (verify with current visa-policy lists, since EU due-diligence reviews can change Schengen status for Caribbean CBI passports). Stacking the SKN passport with UAE residency or the Anguilla HVR programme is one of the most resilient HNW relocation structures available out of France in 2026.
Does CBI investment qualify for any French tax relief?
No — the SISC contribution is a non-refundable payment to a foreign government and provides no French tax deduction or credit.
