1The France–United Kingdom conventions — 2008 and 1963

The relationship runs on two instruments of different generations. The 2008 convention, in force since 18 December 2009 and applicable from 2010, follows the OECD pattern for income and gains and now carries, in its consolidated text, the multilateral instrument's principal-purpose test, under which a treaty advantage can be refused where obtaining it was a principal object of an arrangement. The 1963 convention governs succession duty and has done so since 30 June 1964. Together they give the relationship its geometry: the decisive question is almost never nationality — where France–Monaco turns on who the owner is, France–United Kingdom turns on where the owner lives, and on where the property stands.

Residence does the sorting. A person within the tax of both states is assigned by the tie-breakers of article 4 of the 2008 convention, and the answer carries consequences on both sides of the Channel. The convention also contains a provision peculiar to this convention: under article 29, certain reliefs apply only to the extent the income concerned is actually taxed in the United Kingdom — a clause drafted for the former remittance basis whose operation under the post-2025 residence-based rules is a question for the file, not for assumption.

The 2025 reforms frame every calculation. The United Kingdom's abolition of the non-domiciled regime and the move of inheritance tax to a long-term- residence basis have changed the departure side of the sums for families weighing time in France. This brief states United Kingdom law at the level of orientation only; its verified ground is the French side and the two conventions, and the UK reading belongs with the family's UK advisers.

2The market seen from London

Seen from London, the Riviera's €3M+ villa market divides into three registers where UK ownership has historically concentrated. Saint-Jean-Cap-Ferrat is the narrowest and most expensive on the coast: 159 qualified sales for €2,132M across 2016–2025, at a €6.5M median and a €200.0M ceiling. Cannes and its hills contributed 284 sales for €1,949M at a €4.9M median, while the Saint-Tropez peninsula remains the largest €3M+ register on the coast, at 920 sales for €6,472M. The past 36 months alone account for €3,970M across the three.

Ownership, in aggregate

The public record itself describes how the Riviera is held. This brief reads it in aggregate — the State's transaction register alongside the public company registers, all of it already published, anonymised in processing, and with no individual holding ever identified. Across 10 Riviera communes, 29% of the ownership positions studied are held from outside France, and the United Kingdom accounts for 11% of those foreign-held positions, concentrated on Saint-Jean-Cap-Ferrat, the Cannes hills and the Saint-Tropez peninsula. One structural fact stands out: 100% of UK-resident positions in the current study are held in direct personal ownership, without a company in the chain — the inverse of the corporate pattern that dominates elsewhere on these pockets, and a legible trace of a decade in which United Kingdom legislation aimed successive charges at enveloped dwellings. Whether directness remains the right answer after the reforms of 2025 is one of the questions section I bis takes up.

Aggregates only, drawn from public sources under their re-use conditions; no individual holding is identified or published. Residence attribution follows the address of record. Figures refresh with each edition.

IBuying in France as a UK resident

The process and its costs

The acquisition follows the standard French sequence: offer, compromis de vente with a ten-day cooling-off period, deposit of customarily 10%, conditions precedent, and the authentic deed before the notaire, who collects the duties and registers title. The notaire acts as a public officer rather than as the buyer's counsel, and UK-based buyers typically retain their own advisers in addition. Where a holding structure is contemplated, it is prudent to settle the questions of section I bis before the compromis is signed, since the acquiring vehicle is difficult to change once the process is under way.

The cost of owning

CGI article 964 institutes the annual tax on real-estate wealth above €1,300,000 of taxable assets. For persons not domiciled in France the base comprises French-situs property together with the fraction of any company's shares representing French property (article 964-2°), and because neither of the two conventions extends to wealth taxation, the IFI applies to a UK-resident owner without treaty mediation. The exposure is, however, one-sided by design: the United Kingdom levies no comparable tax, so the IFI is a French cost of carry rather than a double charge. The statute contains one planning window of note — a person who becomes French-domiciled after five years abroad is taxed for five years on French assets only (article 964-1°, al. 2), of direct relevance to a family contemplating the move across the Channel.

Recurring charges follow the property. Taxe foncière runs at communal rates; for furnished secondary residences, communes in the zone tendue — a category that includes the marquee Riviera communes — may vote a surtaxe on the taxe d'habitation for second homes, and the annual occupancy declaration is required of all owners. Because these rates are communal and year-specific, this brief's edition cycle re-verifies them rather than freezing them.

I bisStructures, as questions

The structure question

Holding structures are presented here, in keeping with this line's doctrine, as questions for analysis rather than as recommendations. For a UK-connected buyer the choice runs wider than the French menu, because the family's habitual instruments — the trust above all — meet a French framework that names them expressly.

The trust — the family instrument, named by French law

The structure that most often travels with a UK family is also the one French law treats most explicitly. Where the settlor or any beneficiary is French-domiciled, or the trust holds property situated in France, the trustee is required to declare the trust's constitution, modifications and extinction, its terms, its beneficial owners and the 1 January values of the relevant assets (CGI article 1649 AB); a trustee established outside the European Union acquiring French property enters the same net. Alongside the reporting sits a dedicated levy: article 990 J subjects settlors and beneficiaries to a charge at the highest rate of the IFI scale on the trust's French-situs property — unless those assets are already included in a regular IFI return or declared under article 1649 AB. In practice the levy operates as a compliance backstop rather than an inevitable cost: a properly declared trust does not bear it. The deeper questions — how the trust's gains, distributions and successions are characterised on each side — are precisely the ones to resolve before the compromis, with counsel on both sides of the Channel at the table.

Debt against the IFI — what the code anticipates

The financing conversation runs as it does elsewhere on this coast: a loan from the buyer's bank, secured on a pledged portfolio, so that liquidity remains invested while the debt reduces the taxable base. The mechanics are lawful and the code anticipates them. Acquisition debt owed to a bank is deductible from the IFI base under CGI article 974, while financial assets sit outside that base altogether. The boundaries are three. Loans repaying capital at term are deemed to amortise, the deduction declining pro rata over the loan's life, and by one twentieth a year where no term is fixed. Where taxable property exceeds €5M and debts exceed 60% of its value, the excess is deductible only as to half, unless the borrower shows the loan was not contracted mainly for tax. And the debt must be real — actually drawn, actually serviced, at market terms; routed through a shareholder account of an SCI it ceases to count for valuing the shares (article 973). Leverage moderates the IFI in its early years and fades by design — a calendar best examined before the compromis rather than after.

What the acquisition decides for succession

The succession convention of 21 June 1963 has governed death duties between the two states for six decades, and its architecture — from the treaty text and the BOFiP commentary — is settled. Where the deceased was domiciled in one of the two states, the situs of each asset is fixed exclusively by the convention's article 4: immovables lie where they stand, so the Riviera villa answers to French succession duty whatever the family's domicile. The domicile state then taxes on its own terms and credits the tax of the situs state (articles 6 and 7), a relief that must be claimed within five years of the death. Two boundaries deserve plain statement. The convention's situs rules bind only the non-domicile state, so a France-domiciled estate is assessed under ordinary French law with the credit operating in the opposite direction; and lifetime gifts fall outside the convention altogether, leaving French domestic rules (CGI article 750 ter) in full force — the same gap that gives the démembrement of the Monaco brief its character applies here. Where French duty applies, the scale of CGI article 777 runs progressively to 45% in the direct line beyond €1.8M per share, after the €100,000 per-child allowance of article 779; before France determines the duty, the civil law — matrimonial regime, EU Regulation 650/2012 and its professio juris, French forced heirship — determines who inherits, a question for the family's counsel as much as for its tax adviser.

IISelling as a UK resident

Two states are engaged, in a fixed order. France taxes first, as situs state: the 2008 convention's article 14 §1 assigns gains on French immovables to France, and CGI article 244 bis A levies the non-resident charge with the standard ownership-duration allowances, under which the income-tax component extinguishes after 22 years of ownership and the social levies after 30. Property-rich shares do not change the analysis: article 14 §2 reaches gains on interests in companies, partnerships and trusts whose value derives principally from French real estate, so selling the wrapper rather than the walls remains a French taxing event. Sellers resident outside the European Economic Area should, above the statutory threshold, budget for accredited fiscal representation — a post-Brexit point verified at engagement.

The United Kingdom then follows as residence state, taxing under its own rules and relieving the double charge by credit in accordance with article 24 of the convention. One clause deserves particular attention from the internationally mobile: under article 14 §6, a person who was UK-resident at any time in the fiscal year of disposal or in any of the six preceding fiscal years remains within the United Kingdom's reach under its domestic law — a former London resident selling the villa from a new residence elsewhere is not necessarily outside UK tax merely by having left. Where the property is held through a company, the choice between selling the asset and selling the shares alters the pool of buyers and the analysis on both sides; that choice is best evaluated before marketing begins rather than in the course of negotiation.

Leaving after the sale — a note on the exit tax

Families who sell and then move away from France sometimes ask whether an exit charge applies on departure. The answer is narrower than the name suggests. France's exit tax (CGI article 167 bis) is aimed at securities, not at property: it concerns persons who were French-domiciled for at least six of the ten years before leaving, and taxes the unrealised gains on substantial securities holdings — positions whose combined value exceeds €800,000, or stakes of 50% or more in a company's profits, the second criterion catching a controlling holding whatever its value — as they stand on the day of departure. A villa already sold has settled its own tax under the regimes above, and the sale proceeds themselves are not within the charge. Shares of a family SCI follow the property rather than the portfolio: so long as the company keeps the ordinary income-tax regime, gains on its property-rich shares remain within the real-estate regime (CGI article 150 UB) and outside the exit tax — the French right to tax a later sale being preserved instead by article 244 bis A. A company that has opted for corporation tax changes the classification, and with it the analysis; the option belongs on the pre-departure checklist. The residence clock matters equally: a person who leaves before six years of French domicile within the preceding ten stands outside the latent-gains charge altogether, so the family that tried France for a few years and moved on typically departs untouched; gains already placed under a tax deferral follow their own rules and are reviewed at engagement. Where the machinery does apply, payment is generally deferred, and the assessment lapses automatically where the securities are still held two years after departure — five where the portfolio exceeded €2.57M — or upon a return to France. For most sellers the exit tax is therefore a question of calendar and paperwork rather than of cost; the destination-specific mechanics of the deferral, and its meeting with the United Kingdom's own six-year clause of article 14 §6, are settled at engagement.

IIIRenting — as tenant and as owner

Renting as a tenant

A rental year before purchase remains the classic first step, and for a UK family it carries one caution worth stating clearly: French tax domicile under CGI article 4 B turns on the location of the foyer, the principal place of stay, and the centres of professional and economic interest — none of which defers to a lease. A Riviera villa that becomes the family's effective home can establish French residence, with worldwide consequences, well before any purchase; and since the United Kingdom's 2025 reforms tie its own charges to residence years, the calendar of the trial period now matters on both sides of the Channel. The choice between furnished seasonal lettings and the one-to-three-year civil lease determines exit flexibility, and is best matched to the trial's real purpose.

Renting the villa out

French-source rental income of non-residents is taxed under the minimum-rate regime of CGI article 197 A, at no less than 20% up to the second-bracket ceiling and 30% above it, unless the taxpayer demonstrates a lower worldwide effective rate; social levies apply in addition, at a rate that depends on the owner's social-security affiliation — a recurring post-Brexit point resolved at engagement. The 2008 convention assigns the income to France as situs state (article 6), and the United Kingdom, taxing its residents on the same income, relieves the double charge by credit under article 24. One caution specific to this convention: article 29 conditions certain treaty reliefs on the income being actually taxed in the United Kingdom, so the interaction between the credit and the post-2025 residence-based regime belongs on the adviser's checklist rather than in an assumption.

4What changed

Edition 1 — baseline (July 2026). The instruments as they stand: the convention of 19 June 2008 as modified by the multilateral instrument (principal-purpose test included), and the succession convention of 21 June 1963, in force since 30 June 1964. Watch items for edition 2: the United Kingdom's successive Finance Acts settling the residence-based regime that replaced the non-dom rules in April 2025 and their interaction with article 29; annual Loi de finances movements on the IFI and transfer duties; communal surtaxe votes on the Riviera arc; and the jurisprudence on social levies for third-country residents. The ownership aggregates of section 2 are refreshed with each edition.

5Questions, answered

Does a UK resident pay French wealth tax on a Riviera villa?

Yes, once French real-estate assets exceed €1.3M, whether held directly or through the property fraction of company shares (CGI art. 964). Neither of the two conventions covers wealth taxation, so no treaty relief applies — but the United Kingdom levies no wealth tax, so the charge is never doubled.

Who taxes the gain when a UK resident sells a French villa?

France first, as situs state, under the non-resident levy of CGI article 244 bis A with the ownership-duration allowances; the United Kingdom then taxes as residence state and relieves the double charge by credit (2008 convention, arts. 14 and 24). Property-rich shares are treated as the property itself, and a former UK resident remains within UK reach for six fiscal years after departure (art. 14 §6).

Which country taxes the succession on a French villa?

France, as the state where the property stands: the 1963 succession convention fixes the situs of immovables at their location (art. 4), whatever the family's domicile. The domicile state taxes on its own terms and credits the French duty (arts. 6 and 7), on a claim made within five years of the death. Lifetime gifts fall outside the convention, leaving French domestic rules in full force.

Is rental income from France taxed if the owner lives in the UK?

Yes. France taxes first under the minimum-rate regime of CGI article 197 A, at no less than 20% and 30%, with social levies in addition; the United Kingdom taxes the same income as residence state and credits the French charge (2008 convention, arts. 6 and 24).

Does a trust holding a French villa create French obligations?

Yes, expressly. The trustee must declare the trust — its terms, parties and asset values — once the settlor or a beneficiary is French-domiciled or the trust holds French property (CGI art. 1649 AB), and article 990 J holds a dedicated levy at the top IFI rate in reserve for trusts whose French assets go undeclared. A properly declared trust does not bear the levy; an undeclared one does.

Does a French exit tax apply after selling and leaving?

Rarely, and never on the villa itself. The charge (CGI art. 167 bis) reaches only persons French-domiciled for six of the ten years before departure, and only their unrealised gains on securities — above €800,000 in value, or stakes of 50% or more of a company's profits; the sold villa and its proceeds stand outside, as do family-SCI shares kept under the ordinary income-tax regime (art. 150 UB). Where it does apply, payment is generally deferred and the assessment lapses after two years — five above €2.57M — or upon return to France.

Does a bank loan reduce French wealth tax on a Riviera villa?

Yes. Acquisition debt owed to a bank is deductible from the IFI base under CGI article 974, and pledged financial assets remain outside the tax altogether. The deduction is bounded: interest-only loans are deemed to amortise each year, and where property exceeds €5M and debt exceeds 60% of its value, the excess counts only as to half unless a mainly non-tax purpose is shown.
