You have settled in France after Brexit, you left a Self-Invested Personal Pension (a SIPP, the British contract under which you direct your own pension investments inside a tax-advantaged wrapper) with a United Kingdom provider, and you now wonder where the money is taxed, what happens to the quarter of the fund that United Kingdom law lets you take as a one-off Pension Commencement Lump Sum (a PCLS, the single payment of up to one quarter of your pension rights that the United Kingdom exempts from United Kingdom income tax), and whether moving the fund to a Qualifying Recognised Overseas Pension Scheme (a QROPS, an overseas pension scheme recognised by His Majesty’s Revenue and Customs, the British tax authority, as eligible to receive transfers from United Kingdom schemes) would improve your position. The short answer is that, once you are a French tax resident, France taxes your British private pension drawings as a rule, the France-United Kingdom double tax convention signed on 19 June 2008 (the treaty that allocates taxing rights between the two States) reserves that taxation to France in most private-sector cases, and the transfer to a QROPS is itself a separate decision with its own British charges that does not remove the French taxation of later payments. The longer answer, which is the one that protects your money, runs through the French statutory mechanics of pensions, the precise conditions of the reduced 7.5 per cent levy on capitalised payments, the social charges that attach to pensions, and the method French courts impose for treaty disputes. This article sets out that full reasoning, with the official texts and the court decisions that actually decide these files.<\/p>\n
French readers sometimes assume that because the pension was built up in Britain, Britain keeps the right to tax it. Since Brexit that assumption is wrong in the ordinary case: residence, not the location of the former employer or provider, drives the outcome for private pensions. What follows therefore starts from French domestic law, then applies the treaty, then turns to the lump sum and the QROPS question, and finishes with the procedure for challenging an assessment. Readers concerned only with the British State pension, which follows related but distinct reporting lines, will find the companion analysis of State pension residence and social charges at how the British State pension is taxed in France<\/a>, while the present article covers private provision: occupational schemes, SIPPs, and small pots consolidated over a working life in Britain.<\/p>\n Everything begins with residence. A person who has his or her home (the foyer, meaning the place where the family habitually lives), or the place of his or her principal stay, or the centre of his or her economic interests in France is treated as having his or her fiscal domicile (the domicile fiscal, the connecting factor that makes a person liable to French tax) in France within the meaning of article 4 B of the General Tax Code<\/a>. Once domiciled in France, a person is liable to income tax (the imp\u00f4t sur le revenu, the annual French tax on worldwide income) on all of his or her income, whatever its source. In practice, a British national who lives year-round in Dordogne or Paris, whose spouse and children are schooled there, and whose daily life is organised there, is a French tax resident even though the pension fund sits in London and the former employer was British. The treaty can refine that conclusion where both States claim residence under their own law, through its tie-breaker, but it does not allow a person genuinely settled in France to elect out of French residence by pointing to a British pension.<\/p>\n French domestic law then characterises what the SIPP pays out. Article 79 of the General Tax Code<\/a> provides: “Les traitements, indemnit\u00e9s, \u00e9moluments, salaires, pensions et rentes viag\u00e8res concourent \u00e0 la formation du revenu global servant de base \u00e0 l’imp\u00f4t sur le revenu.” The same article adds: “Il en est de m\u00eame des prestations de retraite servies sous forme de capital”. A pension annuity (the rente, the periodic payment) and a capitalised pension payment (the capital, the one-off payment) therefore both enter aggregate income as a matter of principle. The valuation of that income follows article 158 of the General Tax Code<\/a>, whose paragraph 5 a. brings salaries and pensions within the same computational framework by reference to articles 79 to 90, and whose paragraph b quinquies extends that framework to retirement benefits paid as capital. The practical consequence is a 10 per cent allowance (the abattement de 10 pour cent, the flat-rate deduction applied to salaries and pensions before the progressive scale): each pensioner benefits from a deduction of 10 per cent of the declared pension amount, within annual minimum and maximum limits set by the finance law, before the progressive rate scale is applied. The allowance is automatic; it is not an option and it is not a ruling to be requested.<\/p>\n The treaty then allocates the right to tax. Article 18 of the France-United Kingdom convention in force, published by the British government<\/a>, provides that private pensions and similar remuneration paid for past employment are taxable only in the State where the recipient lives, subject to the government-service reservation of Article 19(2). For a French-resident former employee of a private British company drawing a SIPP or an occupational pension, that sentence means France alone taxes, and the United Kingdom must leave the payment alone, subject to the mechanics of relief at source. Two reservations matter. First, Article 19 covers government service (the pensions of civil servants and local authority employees paid by the State): the paying State often retains the taxing right, so a former National Health Service employee with a National Health Service pension and a former local council officer need individual analysis before assuming the Article 18 outcome. Second, the treaty allocates the right to tax; it does not organise the declaration. The French administration still requires the worldwide pension to be reported on the foreign-income return (the formulaire 2047, the annexe to the French tax return on which income from foreign sources is detailed) and then carried to the main return (the formulaire 2042, the principal French income tax return), with the treaty applied by the French office. Where British tax has been withheld at source despite the treaty, because the British payer had not yet received the residence certification, the remedy runs through the elimination-of-double-taxation article of the treaty and the certification of French residence (the formulaire France-Royaume-Uni 5000 series and the personal residence certificate issued by the French tax office), not through omitting the income from the French return.<\/p>\n French courts impose a strict order of analysis that readers should mirror in any challenge file. The administrative court of appeal of Toulouse recalled, in a pension residence dispute concerning Article 18 of the convention with Israel, a principle of general application to all French tax treaties: “Une convention bilat\u00e9rale conclue en vue d’\u00e9viter les doubles impositions ne peut pas, par elle-m\u00eame, directement servir de base l\u00e9gale \u00e0 une d\u00e9cision relative \u00e0 l’imposition”, and consequently “il incombe au juge de l’imp\u00f4t, lorsqu’il est saisi d’une contestation relative \u00e0 une telle convention, de se placer d’abord au regard de la loi fiscale nationale pour rechercher si, \u00e0 ce titre, l’imposition contest\u00e9e a \u00e9t\u00e9 valablement \u00e9tablie avant de d\u00e9terminer si cette convention fait ou non obstacle \u00e0 l’application de la loi fiscale.” (CAA Toulouse, 1st chamber, 13 October 2022, no. 20TL22832<\/a>). In plain terms, the file must first survive French domestic law \u2014 residence under article 4 B, chargeability under articles 79 and 158 \u2014 and only then does the treaty operate as a shield. A taxpayer who opens his letter to the tax office with the treaty and never addresses domestic chargeability has built the file backwards. The Toulouse court also illustrates how residence evidence is weighed: identity documents, registration on the consular register of French nationals abroad (the registre des Fran\u00e7ais \u00e9tablis hors de France, the consular record of nationals living outside France), removal invoices, and the coherence of declared addresses across years. British residents of France should keep the same discipline in reverse: French lease or title deeds, school certificates, utility contracts, and consistent address history, because the first battle in a pension dispute is often residence itself.<\/p>\n Calculation rigour matters as much as treaty logic. The Court of Cassation recalled, in a pension computation dispute, that only precisely defined quarters count toward the statutory increase, quashing a judgment that had counted quarters from the wrong starting point (the surcote, the uplift to the pension rate for quarters contributed after the full-rate age): the combination of the cited social security articles meant that only whole civil quarters contributed after the statutory age could be retained (Cass. 2nd civil chamber, 8 April 2021, no. 19-23.831<\/a>). The lesson for British pensioners is methodological rather than technical: French pension taxation turns on exact statutory conditions \u2014 dates, thresholds, options exercised expressly \u2014 and approximations in the file, however sympathetic, do not survive judicial review. Keep every P60 (the British end-of-year certificate of earnings and tax paid), every SIPP annual statement, every drawdown illustration, and every exchange of correspondence with the provider, because the later sections of this article show that the reduced levy and the quotient mechanism each depend on documentary proof.<\/p>\n The quarter of the fund that United Kingdom law exempts causes the most expensive misunderstandings in these files, because the United Kingdom exemption does not travel. A British pensioner who draws the Pension Commencement Lump Sum in London, pays no British tax on it, and concludes that nothing is due anywhere has confused the British domestic exemption with the treaty allocation: the treaty gives France the taxing right over the private pension, and France exercises it under its own categories. French law offers three distinct treatments for a retirement benefit paid as capital, and the taxpayer must actively select the best available route rather than assume the British treatment applies by analogy.<\/p>\n The default treatment taxes the capitalised payment with other pension income at the progressive scale, after the 10 per cent allowance, under articles 79 and 158 described above. The second treatment is the reduced levy of article 163 bis of the General Tax Code<\/a>, which provides: “Les prestations de retraite vers\u00e9es sous forme de capital imposables conform\u00e9ment au b quinquies du 5 de l’article 158 peuvent, sur demande expresse et irr\u00e9vocable du b\u00e9n\u00e9ficiaire, \u00eatre soumises \u00e0 un pr\u00e9l\u00e8vement au taux de 7,5 % qui lib\u00e8re les revenus auxquels il s’applique de l’imp\u00f4t sur le revenu.” The levy is computed on the capital reduced by a 10 per cent allowance, and, crucially, it applies only where the payment is not split (the versement non fractionn\u00e9, the requirement that the capital be paid in one instalment) and where the taxpayer proves that the contributions paid during the build-up phase, including any employer contributions, were deductible from taxable income or related to exempt income in the State that had the right to tax that income. The request must be express and irrevocable, made with the return of the year of receipt. For a SIPP funded out of relieved British contributions while the holder worked and was taxed in Britain, that deductibility condition is normally capable of proof through contribution histories and British tax computations, but it must actually be proved with documents, not asserted. The administrative court of appeal of Bordeaux examined exactly this mechanism for a capitalised international pension payment of 411,091 euros arising from an employer-sponsored international pension arrangement, testing the 7.5 per cent levy against the deductibility record and the administrative doctrine on pension capitalisation (CAA Bordeaux, 6th chamber, 3 December 2025, no. 23BX02970<\/a>). The decision is a warning against improvisation: the court worked through article 79, article 158 paragraph 5 a. and b quinquies, and article 163 bis paragraph II in sequence, and measured each condition separately. Taxpayers who cannot evidence the contribution history, or whose capital was paid in instalments, fall back to the progressive scale. Conversely, the administration cannot recharacterise the payment at will: in that same litigation the court scrutinised the attempted substitution of legal basis toward article 120 of the General Tax Code<\/a> (the category of movable capital income, meaning income from shares and securities) and tested whether the sum genuinely had the character of a retirement benefit before accepting any reclassification. Characterisation is therefore a real battleground: keep the scheme rules, the employer plan documents, and the provider’s characterisation of the payment as a pension benefit.<\/p>\n The third treatment is the quotient system (the syst\u00e8me du quotient, the mechanism that softens the progressive scale where income that cannot be collected annually arrives in a single year) of article 163-0 A of the General Tax Code<\/a>, which opens: “Lorsqu’au cours d’une ann\u00e9e un contribuable a r\u00e9alis\u00e9 un revenu qui par sa nature n’est pas susceptible d’\u00eatre recueilli annuellement”, and then allows the tax on such exceptional income above the three-year average to be computed by adding one quarter of it to taxable income and multiplying the resulting extra charge by four. Where the 7.5 per cent levy is unavailable \u2014 for instance because the contribution record from decades ago is incomplete \u2014 the quotient often produces a materially lower bill than raw progressive taxation of the whole capital in one year, and it should be computed comparatively before the return is filed. Small pots commuted in full, trivial commutation payments, and late-discovered deferred benefits each raise the same triage question: progressive scale, 7.5 per cent levy, or quotient. The answer is arithmetic on the taxpayer’s own figures, not doctrine in the abstract, and it must be recomputed each year because thresholds, allowances, and the household composition (the quotient familial, the system of parts that adjusts the progressive scale to household size) move the outcome.<\/p>\n Social charges come on top of income tax and surprise British pensioners who assume that a pension below the income tax threshold costs nothing. Pensions paid to persons fiscally domiciled in France bear the general social contribution and allied levies whose base is defined by article L. 136-6 of the Social Security Code<\/a> for patrimonial income and the surrounding articles for replacement income, with collection mechanics detailed by article L. 136-7 of the Social Security Code<\/a> for investment products subject to withholding. The rate and even the liability depend on health affiliation: a British pensioner who holds a valid S1 healthcare certificate (the portable document by which the United Kingdom, as the State owing the pension, bears the cost of the holder’s healthcare in France) and remains affiliated to the British system for health purposes may be relieved of the health-related component of the charges, while remaining liable for the solidarity components, whereas a pensioner affiliated to the French system through Protection Universelle Maladie (the PUMA, the French universal health protection that covers residents on a stable and regular basis) bears the standard pensioner schedule. Because individual positions vary \u2014 S1 holders, persons with mixed careers, early retirees not yet drawing the State pension \u2014 the only safe method is to have the local health fund (the CPAM, the caisse primaire d’assurance maladie, the local health insurance fund) and the tax office confirm the affiliation in writing before the first drawdown, and to keep the S1, the attestation of rights (the attestation de droits, the document proving entitlement to health cover), and the pension award letters together. Interest and investment growth inside the SIPP wrapper before drawdown, meanwhile, follow the movable income and withholding framework of article 125 A of the General Tax Code<\/a> where distributions or deemed returns fall within its scope, which is why the wrapper should not be treated as invisible: growth realised and paid out is characterised under French categories at the point it reaches the taxpayer.<\/p>\nI.
