You live in France, you kept your British shares after Brexit, and every dividend still arrives in your UK account exactly as it always did. No British tax is deducted, the voucher looks unchanged, and for a year or two nothing seems to happen. Then the French tax bill lands and the shock is genuine: France taxes the gross dividend at up to 31.4 per cent for income received in 2026, the British tax you hoped to set against it turns out to be nil, and neither your bank nor your broker warned you. This is the most common misunderstanding British residents bring to our office about investment income, and it is also one of the most expensive, because the mistake repeats every single year until the return is corrected.
The legal picture is clear once it is laid out in the right order, and Brexit changed none of it. The France-United Kingdom tax treaty, signed in London on 19 June 2008, still decides which country may tax your dividends: France, as your country of residence, has the main right, while the United Kingdom keeps only a capped right of 15 per cent at source. French domestic law then taxes those dividends on a worldwide basis, either at a flat levy or, on election, at the progressive income-tax scale with a 40 per cent reduction. Where British tax has genuinely been paid, the treaty grants a credit, but that credit is strictly capped at the French tax on the same income. This article explains where your UK dividends are taxable, how to pay less through the lawful choice the code offers you, and how to challenge an assessment that misapplies the treaty.
I. Your UK dividends are taxable in France first: the treaty only shares out the bill
A. Why France taxes dividends paid by British companies to residents of France
France taxes its residents on their worldwide income, and that single rule explains almost every surprise in this area. Once you are a French tax resident, dividends from British companies are French taxable income in exactly the same way as dividends from French companies, even though the money never touches a French bank account and even though the paying company has no connection with France. The source of the income does not protect it. Only a treaty provision, applied correctly on your return, can soften the bill.
Residence is therefore the first question to settle, and it is decided by French law, not by where your shares are held or where the dividends are paid. A British citizen who has their home in France, whose family lives there, or who simply spends most of the year there is a French tax resident, and remaining a British citizen or keeping a UK address on the share register changes nothing. Readers unsure of their position should start with our guide to French tax residence for British nationals, which works through the foyer and 183-day tests step by step: British Tax Resident in France: 183 Days, Foyer and Treaty Tie-Break After Brexit. If two countries claim you at once, the treaty tie-break decides, and the courts apply a precise test, discussed below.
Once French residence is established, the charging provision is Article 120 of the General Tax Code (Code général des impôts), which expressly catches foreign investment income: “Sont considérés comme revenus au sens du présent article : 1° Les dividendes, intérêts, arrérages et tous autres produits des actions de toute nature et des parts de fondateur des sociétés, compagnies ou entreprises financières, industrielles, commerciales, civiles et généralement quelconques dont le siège social est situé à l’étranger quelle que soit l’époque de leur création”. The wording is deliberately wide. Every dividend from a company whose registered office sits outside France is covered, whatever the date the company was formed and whatever the account that receives the money: general investment account, nominee account, joint account with a spouse, or dividends left to accumulate with a British platform. Declaring only what you transfer to France is the most frequent error our office corrects. France taxes the dividend when it arises, not when you remit it. There is no remittance basis in French law, so a dividend kept in a British account is taxable in France in full if you lived in France when it was paid, converted into euros at the rate applying on payment.
The year of the move needs particular care. Tax residence can change part-way through a year, and a large final dividend paid just before the move may fall outside French tax while an interim dividend paid just after falls inside it. Keep boarding passes, the lease or completion deed, removal invoices, registration with the French health system and school enrolment letters. The local tax office asks for this kind of evidence whenever the date of arrival is disputed, and the same papers protect you if both countries claim you as a resident for the same year.
B. What the France-United Kingdom treaty gives you: residence taxes, source capped at 15 per cent
The treaty that divides taxing rights is the convention signed at London on 19 June 2008 and published in France by the decree of 7 January 2010. Tax treaties are entirely separate from European Union membership, so every dividend rule described here applies exactly as it did before the United Kingdom left the Union. The official treaty text remains the only authority that counts, and its dividend article sets three distinct rules: who may tax, up to what limit, and what counts as a dividend.
The starting rule favours your country of residence. Under the dividend article of the 2008 treaty, dividends paid from one contracting state to a resident of the other are taxable in that other state, so for a British citizen living in France and receiving dividends from a British company, France may tax. The treaty then preserves a limited right for the source country, but caps it strictly: where the recipient is the beneficial owner, the source tax cannot exceed 15 per cent of the gross dividends. That 15 per cent ceiling is applied in practice. In a Franco-British dividend dispute, the Conseil d’Etat recorded withholding “dont le taux a été limité à 15 % en application de l’article 9 de la convention fiscale franco-britannique”, capped at 15 per cent under the Franco-British treaty. That case applied the earlier 1968 convention; the 2008 treaty carries the same 15 per cent ceiling in its own dividend article, as confirmed against the official treaty text during our research. That beneficial-owner condition matters for nominees and trusts: the person who actually enjoys the dividend must be the French resident claiming treaty protection. The treaty definition of dividends is deliberately broad and follows the distributing company’s domestic law, covering income from shares and comparable profit-sharing rights while excluding debt-claims, so ordinary cash dividends, scrip dividends taken in shares and special dividends all fall inside it, while interest on loans and bonds sits in a separate article with different credit rules. Mixed holdings must therefore be split line by line on the return.
The decisive point for most readers is what happens in practice on the British side. The United Kingdom levies no withholding tax on dividends: British companies pay dividends gross, and the shareholder accounts for any British tax through self assessment against personal allowances and dividend rates. The British government’s own guidance on dividends confirms the current personal position: a yearly dividend allowance of £500, above which dividends are taxed by Income Tax band, with the table for 2026-27 showing 10.75 per cent at the basic rate, 35.75 per cent at the higher rate and 39.35 per cent at the additional rate, while dividends from shares held in an ISA escape British tax altogether. For a French resident, the consequence is sharp. Because no British tax is deducted at source, there is usually no British tax available to credit in France, and the treaty credit described next will therefore often be zero. The treaty does not create a credit out of thin air; it only relieves British tax genuinely suffered. A reader with modest dividends covered by the British personal allowance and the £500 dividend allowance may owe nothing in London and the full French levy in Paris, which feels like double taxation but is legally single taxation by the residence state.
Where British tax has genuinely been paid, the treaty eliminates the remaining double taxation through a capped credit in France. The mechanism sits in the treaty’s article on the elimination of double taxation: for dividends, the French resident is entitled to a credit equal to the British tax paid in accordance with the treaty, capped at the French tax on the same income. Two points in that rule do heavy work. First, only tax paid in accordance with the treaty counts, so a British charge the treaty forbids cannot be passed on to the French Treasury. Second, only tax genuinely and finally borne on the dividends concerned qualifies: provisional payments, refundable amounts and tax attributable to another item of income do not count. The Conseil d’Etat polices that architecture closely. In a ruling on the Franco-British convention of 19 June 2008, it held that “cette condition n’exige pas que les revenus en cause aient été soumis à une imposition effective”, while adding that “la condition prévue à l’alinéa (i) du a) du paragraphe 3 de l’article 24 de la convention doit être regardée comme satisfaite s’il est établi par le résident de France qu’il a déclaré les revenus en cause au Royaume-Uni […] alors même qu’il n’aurait acquitté dans cet Etat aucun impôt à raison de ces revenus”. That ruling concerned employment income falling under paragraph (i) of the credit article, where inclusion in the British tax base suffices; dividends fall under paragraph (ii), where the credit equals British tax actually paid. In both cases the discipline is the same: declare the income on both sides and prove what was finally paid, because a credit that cannot be set against French tax is lost, not refunded.
The French courts enforce that cap strictly. In a case about foreign dividends and the treaty credit, the Nantes administrative court of appeal held: “Il ne résulte pas des stipulations citées au point 8 ni d’aucune disposition ou d’aucun principe de droit national que le crédit d’impôt n’ayant pu faire l’objet d’une imputation soit restitué par la France au résident bénéficiaire de ces revenus.” In plain terms, a credit that cannot be set against French tax is lost, not refunded. The same judgment added that the taxpayer was “n’est pas fondé à soutenir que l’assiette prise en compte pour le calcul du prélèvement à un taux de 21 % tel que prévu à l’article 117 quater du code général des impôts et des prélèvements sociaux correspondants était erronée”, not entitled to challenge the base of the advance levy on the ground that the foreign tax had inflated it. The lesson for British residents is direct: organise the treaty position on the return before payment, because reclaiming an unusable credit afterwards is, as a rule, impossible.
II. Paying the French bill without overpaying: and challenging it when the treaty is misapplied
A. Flat levy or progressive scale: the 2026 calculation that decides your bill
French law offers every resident two ways to be taxed on dividends, and the choice is yours each year. The default is the flat levy, the prélèvement forfaitaire unique: 12.8 per cent income tax on the gross dividend. The alternative, on global election, is the progressive income-tax scale applied to the dividend reduced by a 40 per cent allowance. Social charges, the prélèvements sociaux, apply on top in both cases, and their rate has just risen, which changes the comparison for income received in 2026. Running both calculations before filing is the single most valuable hour a British shareholder in France can spend.
The flat levy is set by Article 200 A of the General Tax Code, and the code states the foreign-dividend rule expressly: “Les revenus mentionnés au premier alinéa du présent 1° de source étrangère sont également retenus pour leur montant brut. L’impôt retenu à la source est imputé sur l’imposition à taux forfaitaire dans la limite du crédit d’impôt auquel il ouvre droit, dans les conditions prévues par les conventions internationales.” Three consequences follow for UK dividends. They enter the levy at their gross amount, with no allowance. Any British withholding is credited, but only within the treaty credit, which, as Part I showed, is usually zero because the United Kingdom withholds nothing. And the levy is additional to social charges. The French tax administration’s own guidance confirms the structure: income from financial investments is subject, as a rule, to a 12.8 per cent flat levy, while a non-final advance is taken when the income is paid (French tax administration guidance on investment income).
That advance, the acompte, is the 12.8 per cent taken at payment time under Article 117 quater, which makes resident recipients of the listed distributions liable to “un prélèvement au taux de 12,8 %”, a levy at the rate of 12.8 per cent. Here British residents meet a welcome subtlety. Where the payer sits outside France, the code narrows the advance: “Lorsque la personne qui assure le paiement des revenus mentionnés au premier alinéa du 1 du I est établie hors de France, seules les personnes physiques appartenant à un foyer fiscal dont le revenu fiscal de référence de l’avant-dernière année, tel que défini au 1° du IV de l’article 1417, est égal ou supérieur aux montants mentionnés au troisième alinéa du 1 du I du présent article sont assujetties au prélèvement prévu au même I.” In practice, a British platform or registrar has no French establishment and levies nothing, so the advance is generally settled on the French return rather than at source. Households whose reference tax income, the revenu fiscal de référence, stood below 50,000 euros for a single person or 75,000 euros for a jointly taxed couple two years earlier may also claim a formal exemption from the advance: “leur demande de dispense des prélèvements prévus aux mêmes I au plus tard le 30 novembre de l’année précédant celle du paiement des revenus mentionnés auxdits I, en produisant, auprès des personnes qui en assurent le paiement, une attestation sur l’honneur”, a request with a sworn statement made no later than 30 November of the year before payment. With a British payer that levies nothing anyway, the exemption matters less, but the thresholds still signal the households the code treats as modest, and they reappear in planning.
The alternative is the progressive scale with the 40 per cent allowance, and British dividends qualify for it. Article 158 of the code grants the allowance to income distributed by companies liable to corporation tax or an equivalent tax, established in the European Union or in a state that has signed a double-tax treaty with France containing an administrative-assistance clause, following a proper corporate decision: “Les revenus mentionnés au 1° distribués par les sociétés passibles de l’impôt sur les sociétés ou d’un impôt équivalent ou soumises sur option à cet impôt, ayant leur siège dans un Etat de l’Union européenne ou dans un Etat ou territoire ayant conclu avec la France une convention fiscale en vue d’éviter les doubles impositions en matière d’impôt sur les revenus qui contient une clause d’assistance administrative en vue de lutter contre la fraude et l’évasion fiscales et résultant d’une décision régulière des organes compétents, sont réduits, pour le calcul de l’impôt sur le revenu, d’un abattement égal à 40 % de leur montant brut perçu”. The United Kingdom satisfies that test through the 2008 treaty, so dividends voted by an ordinary British company qualify. The administration’s own guidance confirms the result: under the scale, share dividends and other distributions are taxed after a 40 per cent allowance computed automatically on the gross amount. The election is global, covering all investment income and securities gains, and it is made by ticking box 2OP on the return. Since 2026 that election is no longer irrevocable from one year to the next, as the administration’s guidance on the progressive-scale election confirms. A household can therefore test the scale one year and return to the flat levy the next.
Social charges complete the bill, and 2026 brings a rise every British shareholder must price in. Dividends, as investment income, fall within the contribution on patrimonial income, whose base is set by Article L. 136-6 of the Social Security Code: “Les personnes physiques fiscalement domiciliées en France au sens de l’article 4 B du code général des impôts sont assujetties à une contribution sur les revenus du patrimoine assise sur le montant net retenu pour l’établissement de l’impôt sur le revenu”, including “c) Des revenus de capitaux mobiliers”. The administration states the rates plainly: investment income paid in 2025 bore social charges at 17.2 per cent, while from 1 January 2026 the rate rises to 18.6 per cent, with the listed exceptions confined to older savings products, so dividends move to 18.6 per cent. The arithmetic for 2026 dividends is therefore 12.8 plus 18.6, a combined 31.4 per cent under the flat levy, against 30 per cent for 2025 income. Take a gross UK dividend of 10,000 euros received in 2026: the flat route costs 1,280 euros of income tax and 1,860 euros of social charges, 3,140 euros in total. Under the scale at an 11 per cent marginal rate, the income-tax element falls to 660 euros on the 6,000-euro base after the allowance, a saving of 620 euros before social charges, while at a 30 per cent marginal rate the same element rises to 1,800 euros and the flat levy wins. The breakeven sits between those bands, which is why the calculation must be run with the household’s real marginal rate, including the spouse’s income, before the return is signed.
Two British wrappers deserve a warning because they mislead even careful readers. The stocks and shares ISA shelters dividends from British tax, but France does not recognise the wrapper: with no French provision exempting them, ISA dividends fall squarely within Article 120 and are taxable in France in full, which is why holding British equities inside an ISA after moving to France often destroys the wrapper’s entire purpose. Likewise, dividends automatically reinvested by a British accumulation fund or left as stock dividends are taxable when credited, not when eventually sold. And where the treaty credit is claimed, remember the Nantes lesson from Part I: claim only British tax genuinely and finally paid, because an unusable credit is lost rather than refunded.
B. Declaring the dividends and challenging double tax: forms, deadlines and courts
Declaration follows a fixed path. British dividends are foreign income, so they are entered on the foreign-income schedule, form 2047 (Cerfa 11226), whose official notice and filing route the public service confirms online (declaring foreign income: form 2047), and carried onto the main return, form 2042. Report the gross dividend in euros, set nothing against it, and attach the treaty credit only where British tax was genuinely paid. Keep every voucher, the platform’s annual statement, the exchange rate used, and, where a credit is claimed, the British self-assessment computation showing the tax as final. The administration increasingly cross-checks British payments against automatic exchange-of-information data, so a dividend omitted because it “stayed in London” is now the fastest route to a reassessment with interest and penalties.
When the assessment is wrong, French procedure imposes a strict order: the written claim first, the court second. Article R*190-1 of the Tax Procedure Book requires the taxpayer to complain to the local office of the revenue administration before any court action: “Le contribuable qui désire contester tout ou partie d’un impôt qui le concerne doit d’abord adresser une réclamation au service territorial, selon le cas, de la direction générale des finances publiques ou de la direction générale des douanes et droits indirects dont dépend le lieu de l’imposition.” That claim has its own deadline: for taxes of this kind it must reach the administration “au plus tard le 31 décembre de la deuxième année suivant celle” of collection, payment or the event founding the claim, at the latest on 31 December of the second following year. Miss that date and the substance of the treaty argument becomes irrelevant, however strong. A claim that the British credit was refused, that the 40 per cent allowance was denied on qualifying UK dividends, or that social charges were applied at the wrong year’s rate should therefore be filed in writing, with vouchers and treaty references, as soon as the notice is understood.
If the administration rejects the claim or stays silent, the court route opens under Article R*199-1: “L’action doit être introduite devant le tribunal compétent dans le délai de deux mois à partir du jour de la réception de l’avis par lequel l’administration notifie au contribuable la décision prise sur la réclamation”, two months from receipt of the rejection, while a taxpayer left without an answer for six months “peut saisir le tribunal dès l’expiration de ce délai”, may go straight to the court when that period expires. The competent court is the administrative tribunal of the place of taxation, which decides the treaty reading, the allowance and the credit on the evidence filed. Appeals go to the administrative court of appeal, and points of law to the Conseil d’État, which polices treaty interpretation closely.
One Conseil d’État ruling matters directly to British residents because it governs who counts as a treaty resident when the administration disputes the status. The court annulled an appeal judgment that had demanded proof of unlimited tax liability abroad, holding that the lower court should only have asked whether the other state taxed the person by reason of a personal link rather than merely local source: “alors qu’il lui appartenait seulement de rechercher si cet Etat l’assujettissait à l’impôt, le cas échéant sur certains seulement de ses revenus, en raison d’un lien personnel et non simplement de leur source locale, la cour a commis une erreur de droit.” For a British national taxed in the United Kingdom on some income by reason of personal ties, that test protects treaty access even where the foreign liability is limited to certain items. In a dispute over the dividend article or the credit, that paragraph belongs in the written claim from the start, because it frames the residence question the administration must answer before it can deny treaty relief.
fights are won on papers, so assemble the file as the treaty requires. Proof of French residence and of its starting date. Proof that the distributing company is liable to an equivalent of corporation tax and that the dividend flowed from a proper corporate decision, for the 40 per cent allowance. Proof of beneficial ownership where nominees stand between you and the register. Proof of British tax finally paid where a credit is claimed, with the self-assessment and any repayment notices. And the dividend vouchers with euro conversions. An administration that receives that file with the first claim very often corrects the assessment without litigation; one that receives bare assertions issues a standard rejection, and the two-month court clock starts running.
Conclusion
British dividends in French hands follow a short chain of rules, and each link must be checked in order. France taxes because you live in France, under Article 120, on the gross amount, with no remittance basis. The 2008 treaty gives France the main right and caps the British source tax at 15 per cent, while the United Kingdom in practice withholds nothing, so the French credit for British tax is usually zero and unusable credits are lost, not refunded. French law then offers a genuine choice: the flat levy, 31.4 per cent all-in for 2026 income at 12.8 plus 18.6, or the progressive scale on 60 per cent of the dividend, elected yearly through the 2OP box and no longer irrevocable. For 2026 the scale typically wins at low marginal rates and loses at high ones, which is why the calculation must be run afresh with each return. Declaration runs through forms 2047 and 2042 on the gross euro amount, and challenges run through a written claim by 31 December of the second following year, then the administrative tribunal within two months. Fix the return this spring, keep the vouchers the treaty demands, and the bill stops repeating.
