You sell up in Kent, buy a stone house near Sarlat, and register with the local mairie<\/em> (town hall) as a new arrival. Your UK State Pension keeps arriving, your former employer’s occupational pension follows each month, and before the move you take the familiar 25 per cent lump sum that is free of UK tax. Then three letters arrive in the same winter. The French tax office taxes the whole of your British pensions, including the lump sum you believed was settled. HM Revenue and Customs goes on deducting UK tax from a pension that the treaty may give to France. And a social charges demand adds more than eight per cent on top of income tax. Every one of those bills can be correct, partly wrong, or wholly challengeable, and the difference turns on four questions: where you are tax resident, what the France-UK double tax treaty allocates to each State, how France taxes pension capital and transfers, and whether you belong to the French health system for social charges. This article answers each question with the exact legal texts and court decisions, so you can check your assessment line by line and know when to fight it.<\/p>\n

The short answer is that France taxes your worldwide pensions once you are French tax resident, and the treaty then gives France the exclusive right to tax your private, occupational and State pensions, while pensions for British government service stay taxable in the United Kingdom unless you are both resident and solely a French national. Your pensions enter global income with a 10 per cent allowance capped at 4,439 euros, your 25 per cent lump sum that was free of UK tax is taxable in France with a choice between the quotient system and a 7.5 per cent flat charge, a direct transfer to a recognised overseas scheme is not itself a payout but every pound you draw afterwards is, and the 8.3 per cent social charge on pensions falls away where you are covered by a British S1 certificate rather than the French health system. Where the administration gets any of this wrong, a formal claim suspends the disputed part of the bill and the courts must hear you. The detail below shows how to use each rule.<\/p>\n

I. Where your UK pension is taxed once you live in France after Brexit<\/h2>\n

Before any rate or allowance matters, one allocation decides everything: which State is entitled to tax each of your pensions. Get the residence and treaty analysis right and the rest of the return writes itself. Get it wrong and you will either pay twice or invite penalties. The two steps below follow the order the French administration itself applies, residence first and treaty second.<\/p>\n

A. When do you become French tax resident with a British pension?<\/h3>\n

French domestic law uses three alternative tests, and meeting any one of them makes you French tax resident. The statute provides that “Sont consid\u00e9r\u00e9es comme ayant leur domicile fiscal en France au sens de l’article 4 A : a. Les personnes qui ont en France leur foyer ou le lieu de leur s\u00e9jour principal” (Article 4 B of the General Tax Code<\/a>). The same article adds professional activity in France and the centre of economic interests as two further tests. In practice the first test decides most retiree cases: where your foyer<\/em> (the family home where your spouse and household normally live) sits, or failing a settled family home, where your s\u00e9jour principal<\/em> (the place of your main physical presence, commonly measured at 183 days in the year) sits. A British couple who keep a London flat for visits but live year-round in the Dordogne, with their furniture, doctor, club memberships and daily life there, are French tax resident even if bank accounts and a UK passport remain.<\/p>\n

The 183-day shorthand misleads many new arrivals. A day count is only one indicator of the main stay, and the foyer<\/em> test can make you resident with fewer than 183 days in France where your household has plainly moved, while 183 days abroad do not protect you where France remains the centre of family life. The administration looks at the bundle of evidence as a whole: the address on your carte de s\u00e9jour<\/em> (residence permit), your registration with the French health system, the place where your spouse lives, where your cars are insured, and where you spend ordinary Tuesdays rather than holidays. Keep the documents that prove the real pattern, because the same bundle will decide your treaty position below, and because a wrong residence claim is the fastest route to a reassessment with interest.<\/p>\n

Residence under domestic law is only the first half. Where both States claim you, the treaty’s tie-breaker decides, and the same article warns that persons meeting a domestic test “ne peuvent toutefois pas \u00eatre consid\u00e9r\u00e9es comme ayant leur domicile fiscal en France lorsque, par application des conventions internationales relatives aux doubles impositions, elles ne sont pas regard\u00e9es comme r\u00e9sidentes de France” (Article 4 B of the General Tax Code<\/a>). The France-UK convention then works through its own cascade of permanent home, centre of vital interests, habitual stay and nationality. A retiree with a permanent home available in both countries, which is the common case in the first years after a move, is deemed resident where personal and economic relations are closer, and the administration will ask exactly the questions described above. Prepare one coherent residence story for both tax offices rather than two convenient ones, because inconsistent claims surface as soon as the two administrations exchange information.<\/p>\n

Once French residence is established, the scope of French tax follows at once. French law provides that “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” (Article 79 of the General Tax Code<\/a>). Your British pensions therefore enter the revenu global<\/em> (your total worldwide income assessed together in France) in the year you become resident, and must be declared even where the treaty ultimately gives the United Kingdom the right to tax a particular pension, because France needs the figures to apply exemption-with-progression and to compute social charges correctly. Declare on the standard return, form 2042, with foreign pensions detailed on the foreign-income annex, form 2047, and keep the P60, P45 and annual pension statements that reconcile every figure. The tax administration guidance confirms the same 10 per cent allowance, capped at 4,439 euros for 2025 income for the whole tax household (impots.gouv.fr, Pensions de retraite<\/a>), which mirrors the statute stating that “Les pensions et retraites font l’objet d’un abattement de 10 % qui ne peut exc\u00e9der 4 439 \u20ac” (Article 158, 5, a of the General Tax Code<\/a>).<\/p>\n

The mirror situation matters for readers who have not yet moved or who split the year. Pensions of French source paid to persons who are not French tax resident attract a withholding at source, since “les traitements, salaires, pensions et rentes viag\u00e8res, de source fran\u00e7aise, servis \u00e0 des personnes qui ne sont pas fiscalement domicili\u00e9es en France donnent lieu \u00e0 l’application d’une retenue \u00e0 la source” (Article 182 A of the General Tax Code<\/a>). A British reader drawing a French pension while still UK resident therefore faces French withholding first and a treaty claim second, which is the reverse of the main retiree case. In the arrival year itself, take advice before filing as resident for the whole year or sequencing the move, because the date residence starts fixes which pensions each State may tax and which return each pension belongs on.<\/p>\n

B. What does the France-UK double tax treaty say about your state, workplace and private pensions?<\/h3>\n

The treaty rule for ordinary pensions is short and decisive. It gives the State of residence the sole right to tax pensions and similar payments made for past employment, subject only to the government-service exception in Article 19, paragraph 2 (Article 18 of the 2008 UK-France Double Taxation Convention<\/a>). For a British retiree who is French resident, that sentence moves the UK State Pension, a former employer’s occupational pension and a personal pension to France alone. The United Kingdom must give up its tax, typically through a claim to HM Revenue and Customs for relief at source or repayment, and France taxes the full amount under its own rules. The British guidance puts the general point plainly for readers checking the UK side, noting that you may be taxed by both States but that a double taxation agreement means you pay once, with each treaty allocating the right (GOV.UK, Tax when you live abroad<\/a>).<\/p>\n

The exception concerns pensions for government service, and it runs the other way. For pensions paid by a State, a local authority, or a body set up by them, for work performed for that body, only the paying State may tax, except where the pensioner lives in the other State and holds solely that other State’s nationality, in which case only that other State may tax (Article 19, paragraph 2 of the 2008 UK-France Double Taxation Convention<\/a>). A classic British civil service or local government pension paid to a British national living in France therefore stays taxable only in the United Kingdom, while the same pension paid to a retiree who is resident in France and solely a French national moves to France. Check the payer and the funding rather than the job title: a pension paid out of a fund created by the State or the authority for its servants falls inside this article, while a privatised employer’s scheme or a top-up personal pension beside it falls under Article 18 and goes to France.<\/p>\n

Each pension in the household needs its own classification, because a retired couple commonly hold a mix. Take a household where the husband draws a UK State Pension and a former private-sector occupational pension while the wife draws a British local-authority pension. On the analysis above, the husband’s two pensions are taxable only in France under Article 18, and the wife’s local-authority pension is taxable only in the United Kingdom under Article 19 unless she is solely a French national resident in France. France still requires the worldwide picture on the return, and the treaty mechanism for a pension taxable only in the United Kingdom is exemption in France with the income counted for the progressive rate on the remaining French-taxable income. The French tax administration’s treaty commentary for the United Kingdom follows the same structure, allocating each category article by article (BOFiP, Convention fiscale France\u2013Royaume-Uni<\/a>).<\/p>\n

Two practical errors recur every season. The first is leaving the UK payroll code unchanged after the move, so HM Revenue and Customs goes on deducting Pay As You Earn from a pension that belongs to France, and the retiree pays in France as well while waiting. File the treaty claim promptly, keep the HM Revenue and Customs repayment notices, and reconcile them against the French avis d’imposition<\/em> (the formal tax assessment notice) so no pension is taxed twice and none escapes. The second is assuming that a pension taxed in the United Kingdom under Article 19 needs no French declaration. It must still be declared so France can apply the correct rate to the rest of the income, and undeclared worldwide income is the classic trigger for a reassessment that then questions everything else in the file.<\/p>\n

II. How your lump sum, QROPS transfer and yearly pension are taxed and charged in France<\/h2>\n

Residence and treaty tell you which State taxes each pension. This second part tells you how France computes the bill once a pension is hers: the yearly income tax on the pension flow, the special regimes for capital paid out of a pension, the treatment of a transfer to an overseas scheme, and the social charges that sit on top of income tax with their own exemption for S1 holders. Read it as a checklist against your assessment.<\/p>\n

A. Why is your 25 per cent tax-free lump sum and your QROPS transfer still caught in France?<\/h3>\n

The cruellest surprise in this desk’s files is the lump sum. In Britain you may take up to a quarter of a pension pot as a commencement lump sum free of UK tax, and the withdrawal feels like a closed chapter. In France the chapter reopens, because French law taxes retirement benefits paid as capital just as it taxes pensions paid as income: “Il en est de m\u00eame des prestations de retraite servies sous forme de capital” (Article 79 of the General Tax Code<\/a>). Where Article 18 of the treaty gives France the pension, it gives France the lump sum with it, since the lump sum is paid in consideration of the same past employment. The fact that London charged nothing does not bind Paris, and the treaty offers no credit for tax that was never paid. A retiree who takes the 25 per cent in the spring and moves to France in the autumn must therefore plan for French tax on money that was free at home, and the timing of the move against the payment date can change the entire outcome.<\/p>\n

France softens the blow on genuine pension capital with two alternative reliefs, and the choice between them is the most valuable decision in this article. The official guidance explains that where you receive retirement benefits as capital, including a one-off payment replacing a small pension, you may ask for the quotient system or choose flat taxation at 7.5 per cent on your return (impots.gouv.fr, Pensions de retraite<\/a>). The flat charge equals 7.5 per cent of the capital after a 10 per cent reduction (impots.gouv.fr, Pensions de retraite<\/a>). It is available only where two conditions cumulate: the capital is paid in one undivided sum, and the contributions paid while the rights were built up, including any employer share, were deductible from taxable income (impots.gouv.fr, Pensions de retraite<\/a>). A single undivided payment out of a scheme whose contributions attracted relief fits; instalments spread over two tax years, or a scheme funded from already-taxed savings, do not.<\/p>\n

The quotient alternative works differently and suits different cases. The guidance presents it as adding one quarter of the exceptional income to ordinary income, working out the extra tax caused, and multiplying that extra tax by four (impots.gouv.fr, Pensions de retraite<\/a>). In plain terms the capital is cut into four notional slices, one slice is added to your ordinary income to find the extra tax that slice causes, and four times that extra tax is the charge on the whole capital, paid in one year. The method also lowers the revenu fiscal de r\u00e9f\u00e9rence<\/em> (the reference income figure that controls housing-tax thresholds and social benefits) compared with taxing the capital as ordinary income. As a rule of thumb, the 7.5 per cent flat charge wins for large lump sums drawn by households with comfortable yearly income, while the quotient wins for modest capital added to modest income, but the only safe method is to compute both on the actual figures before ticking the box, because the option once exercised for the year cannot be reworked at leisure. Declare capital in the dedicated box of the supplementary return, form 2042-C, and keep it out of the ordinary pension boxes, since mixing the two destroys both reliefs.<\/p>\n

Transfers to a qualifying recognised overseas pension scheme, universally known as a QROPS, raise a separate question: is the transfer itself a taxable payout. The British side polices the transfer with its own charge. The official guidance warns that a transfer to a scheme that is not a QROPS may be refused by the UK scheme or taxed at 40 per cent or more, and that even a transfer to a genuine QROPS can attract a 25 per cent overseas transfer charge on the sums moved where no exemption applies, with a further charge possible where residence changes within five years of the move (GOV.UK, Transferring to an overseas pension scheme<\/a>). Take these British warnings seriously before instructing any transfer, because an adviser who promises a costless move is selling rather than advising.<\/p>\n

On the French side the principle is that a direct trustee-to-trustee transfer, where no sum is placed at your disposal and you cannot spend a penny of it, is not a distribution of pension income and is not taxed as such in the year of transfer. Every later withdrawal from the receiving scheme is then taxed under the ordinary pension rules above, with the treaty allocating each payment. Three cautions qualify the principle. First, any cash skimmed off during the transfer, including a fresh commencement lump sum taken to fund the move itself, is a capital benefit taxed as one. Second, the receiving vehicle matters: a transfer into a French plan d’\u00e9pargne retraite<\/em> (the statutory retirement savings plan, universally shortened to PER) or into a foreign contract with an identifiable capital value creates reporting and valuation duties that a simple pension-to-pension move avoids. Third, the transfer never changes the treaty classification of the rights: moving a British government-service pension into an overseas wrapper does not convert it into a private pension taxable in France, and moving a private pension does not make it taxable in London. Keep the transfer deeds, the scheme documents showing no individual disposal, and the first statements of the receiving scheme, because the tax office will ask for exactly those papers when it queries the year of transfer.<\/p>\n

A French court decision usefully marks the boundary between capital and social charges, even though it concerned a French supplementary scheme rather than a British pension. The Cour de cassation held: “Il r\u00e9sulte de ces dispositions que n’entrent pas dans l’assiette de la contribution sur les revenus d’activit\u00e9 et de remplacement per\u00e7ue au titre de la CSG et de la CRDS, ni dans celle de la cotisation due au titre des assurances maladie, maternit\u00e9, invalidit\u00e9, d\u00e9c\u00e8s, les sommes vers\u00e9es au b\u00e9n\u00e9ficiaire d’un contrat de retraite suppl\u00e9mentaire \u00e0 cotisations d\u00e9finies qui exerce la facult\u00e9 de rachat pr\u00e9vue \u00e0 l’article L. 132-23, alin\u00e9a 2, du code des assurances, dans sa r\u00e9daction applicable au litige” (Cour de cassation, Second Civil Chamber, 8 October 2020, appeal no. 19-16.078<\/a>). The lesson for British readers is a contrario: exceptional buy-backs of French top-up schemes can escape the social base entirely, but ordinary British pension income paid to a person affiliated to the French health system stays inside it. Do not read an income-tax relief on capital as an automatic exemption from social charges, and do not assume that because one capital payment escaped charges, your monthly pension will.<\/p>\n

B. When do CSG and CRDS apply to a British pension and how do you challenge the bill?<\/h3>\n

Social charges are the second bill, and they obey their own membership test. The contribution on employment and replacement income catches only persons who meet two conditions together: “Les personnes physiques qui sont \u00e0 la fois consid\u00e9r\u00e9es comme domicili\u00e9es en France pour l’\u00e9tablissement de l’imp\u00f4t sur le revenu et \u00e0 la charge, \u00e0 quelque titre que ce soit, d’un r\u00e9gime obligatoire fran\u00e7ais d’assurance maladie” (Article L. 136-1 of the Social Security Code<\/a>). Tax residence alone is therefore not enough. A French tax resident whose health cover sits elsewhere, which is precisely the position of a British retiree holding a British S1 certificate, fails the second limb and falls outside the charge. The standard rate on pensions is stated without ambiguity: “Sont assujetties \u00e0 la contribution au taux de 8,3 % les pensions de retraite, et les pensions d’invalidit\u00e9” (Article L. 136-8 of the Social Security Code<\/a>), with reduced rates for modest households under the income thresholds set in the same article. Add the companion debt-repayment contribution and the total levy on a full-rate pension exceeds nine per cent before income tax is even computed, which is why the exemption below is worth real money.<\/p>\n

The S1 exemption is written into the statute. The code provides that “ne sont pas redevables de la contribution les personnes qui, par application des dispositions du r\u00e8glement (CE) n\u00b0 883\/2004 du Parlement europ\u00e9en et du Conseil du 29 avril 2004 sur la coordination des syst\u00e8mes de s\u00e9curit\u00e9 sociale, rel\u00e8vent en mati\u00e8re d’assurance maladie d’une l\u00e9gislation soumise \u00e0 ces dispositions et qui ne sont pas \u00e0 la charge d’un r\u00e9gime obligatoire de s\u00e9curit\u00e9 sociale fran\u00e7ais” (Article L. 136-6, I ter of the Social Security Code<\/a>). The S1 form, issued by Britain and registered with the French caisse primaire d’assurance maladie<\/em> (the local health fund, universally called the CPAM), keeps you under British legislation for health cover under the coordination rules that the Withdrawal Agreement preserved, so you are not borne by a French compulsory scheme and the contribution has no hook. In practice the exemption fails for paperwork reasons rather than legal ones: the S1 was never registered with the CPAM, the tax office was never told, or the pension was declared in a box that automatically triggers the levy. Register the S1 before the first return, attach a copy to the return each year the administration asks, and check the detailed calculation notice to confirm the social charges line is zero where it should be.<\/p>\n

Courts see these disputes constantly, and recent decisions show how strictly judges check the affiliation facts. In two 2025 rulings the Second Civil Chamber of the Cour de cassation rejected refund claims from persons domiciled in France but working in Switzerland who sought repayment of French health contributions and levies, after examining precisely which legislation covered them and on what base the charges were computed (Cour de cassation, Second Civil Chamber, 25 September 2025, appeal no. 22-24.634, and appeal no. G 22-20.036). The message for British retirees is symmetrical: courts grant refunds where the claimant proves cover under another State’s legislation with documents, and they dismiss claims where the file contains assertions instead of proof. Arrive with the registered S1, the CPAM attestation of registration, the British certificate of continuing cover, and the assessment showing the levy, and the claim is documented. Arrive with a complaint about fairness and it is not.<\/p>\n

Where a bill is wrong, the procedure is a formal r\u00e9clamation contentieuse<\/em> (the written claim to the tax administration disputing the assessment), and the time limit is strict: “Pour \u00eatre recevables, les r\u00e9clamations relatives aux imp\u00f4ts autres que les imp\u00f4ts directs locaux et les taxes annexes \u00e0 ces imp\u00f4ts, doivent \u00eatre pr\u00e9sent\u00e9es \u00e0 l’administration au plus tard le 31 d\u00e9cembre de la deuxi\u00e8me ann\u00e9e suivant celle, selon le cas : a) De la mise en recouvrement du r\u00f4le ou de la notification d’un avis de mise en recouvrement” (Article R*196-1 of the Tax Procedures Book<\/a>). File online through your personal space on the tax website or by recorded delivery letter to the office that issued the assessment, identify each disputed line with the correct legal basis from this article, annex the S1 and treaty analysis where relevant, and quantify the discharge sought to the euro. A claim that merely says the bill feels too high, without saying which line offends which text, earns a template rejection.<\/p>\n

Filing the claim also protects your cash flow if you ask for it expressly. The statute states: “Le contribuable qui conteste le bien-fond\u00e9 ou le montant des impositions mises \u00e0 sa charge est autoris\u00e9, s’il en a express\u00e9ment formul\u00e9 la demande dans sa r\u00e9clamation et pr\u00e9cis\u00e9 le montant ou les bases du d\u00e9gr\u00e8vement auquel il estime avoir droit, \u00e0 diff\u00e9rer le paiement de la partie contest\u00e9e de ces impositions et des p\u00e9nalit\u00e9s y aff\u00e9rentes” (Article L. 277 of the Tax Procedures Book<\/a>). This sursis de paiement<\/em> (the statutory deferral of the disputed part while the claim is examined) must be requested in the claim itself with the amount specified; it is not granted automatically. Above the amount fixed by decree the administration may require guarantees, so large lump-sum disputes need a guarantee proposal in the same envelope. If the administration rejects the claim, the next forum depends on the line disputed: income tax and the flat charge go to the tribunal administratif<\/em> (the administrative court), while CSG, CRDS and health contributions on pensions go to the judicial courts, currently the tribunal judiciaire<\/em> (the ordinary civil court) with its social chamber. Sending each dispute to the wrong court wastes the limitation period for the right one, so split mixed assessments accordingly.<\/p>\n

Conclusion<\/h2>\n

A British retirement in France works financially where four papers are in order before the first French return: a residence analysis that would survive both tax offices, a pension-by-pension treaty classification separating Article 18 pensions from Article 19 government-service pensions, a capital strategy that chooses between the quotient and the 7.5 per cent charge on any lump sum instead of discovering the tax afterwards, and a registered S1 that switches off the 8.3 per cent social charge where it should. The 10 per cent allowance, the treaty exemption mechanics and the deferral of the disputed part while you argue are not favours to be requested politely; they are rights written in the articles quoted above, and the courts apply them where the file proves the facts. Keep the P60s, the transfer deeds, the S1 registration and every assessment, check each line of the calculation notice against the texts, and challenge promptly within the claim period where a line offends them. The administration corrects documented files far more readily than it answers complaints, and a judge decides on the papers you kept.<\/p>\n
