For many British people who have moved to France after Brexit, taking pension cash is not simply a matter of asking a UK provider to release the tax-free portion and transferring the money to a French bank account. The United Kingdom may describe up to 25% of a pension as tax-free cash, while France may treat the same payment as a retirement benefit paid in capital form. The result can be a French filing obligation, a choice between two domestic calculation methods, and a separate question about whether the UK has withheld tax under the France–UK treaty.
The first question is not “is this money tax-free in Britain?” It is “what is the legal nature of this payment, who was resident where when it was received, and which treaty article allocates the taxing right?” A pension commencement lump sum, an uncrystallised funds pension lump sum, a small-pot payment, a full encashment and a payment from a public-service scheme can produce different evidence and, in some cases, a different result. The French 7.5% route is not automatic, and the quotient method is not an exemption. Both require accurate classification and a return that matches the provider’s documents.
This article deals with a one-off UK pension lump sum received by an individual living in France. It explains the residence and treaty analysis, the French 7.5% option and quotient method, the forms and evidence to keep, and the procedure for challenging an assessment. It does not replace a calculation based on the pension deed, contribution history, payment statement and the year concerned.
I. Is a UK pension lump sum taxable in France after Brexit?
A. Why UK tax-free cash can still be reportable in France
The starting point is French tax residence, not British nationality and not the label used by the pension provider. The French expression domicile fiscal means the person’s tax residence. Under Article 4 A of the French General Tax Code, the rule is stated in these words: “Les personnes qui ont en France leur domicile fiscal sont passibles de l’impôt sur le revenu en raison de l’ensemble de leurs revenus.” In English, a person whose tax residence is in France is assessed there on the whole of their income, subject to a treaty or a specific exemption.
Article 4 B of the same Code identifies the principal residence indicators. It begins: “Sont considérées comme ayant leur domicile fiscal en France”. The relevant tests include the household or main place of stay, professional activity and the centre of economic interests. Article 4 B also says that a double-tax treaty can prevent France from treating a person as resident when the treaty assigns residence to the other state. A British owner who spends time in both countries therefore needs a documented analysis rather than a simple day count.
Once French residence is established, the domestic classification of the receipt matters. Article 79 of the General Tax Code provides that “Les traitements, indemnités, émoluments, salaires, pensions et rentes viagères concourent à la formation du revenu global servant de base à l’impôt sur le revenu.” The same article expressly includes retirement benefits paid in capital form. This is why a single payment cannot be ignored merely because it is not a monthly pension. A capital payment can be a pension benefit for French income-tax purposes.
The official French tax administration gives the same practical warning on its page about retirement pensions: retirement benefits are generally taxable whatever the pension regime or form of payment, and capital-form retirement benefits must be considered. The page specifically discusses the quotient system and the 7.5% flat-rate option. It is therefore unsafe to copy the UK provider’s phrase “tax-free lump sum” into a French return without checking what was paid.
Under GOV.UK guidance on tax-free pension cash, a person can usually take up to 25% of a pension tax-free, subject to the applicable UK limits and protections. That statement describes the UK treatment. It does not decide the French treatment. The UK label may reflect a UK exemption at source, while France asks whether the payment is a retirement benefit, whether it is a pension paid under the treaty, and whether the French conditions for a domestic relief are met.
There are several common payment patterns:
- A pension commencement lump sum, often called PCLS, is the cash taken when benefits are first accessed, normally up to 25% of the crystallised pension rights. The provider’s statement should identify it as a pension commencement payment and show the gross amount and any UK tax deducted.
- An uncrystallised funds pension lump sum, or UFPLS, is usually a payment from uncrystallised rights. It may contain a tax-free element and a taxable element under UK rules. France will need the provider’s breakdown rather than an assumption that the entire receipt is tax-free.
- A full encashment or a small-pot payment may be paid in one transaction but can still be treated as a retirement benefit. The fact that the payment is described as a “withdrawal” does not turn it into a bank-account withdrawal.
- A transfer to another pension arrangement is not the same event as a payment to the individual. A transfer statement, a payment statement and a bank credit must not be confused with one another.
- A public-service pension can fall under different treaty wording from a private or occupational pension. The identity of the paying scheme and the employment that created the rights must be recorded.
The distinction between a return of the individual’s own capital and a pension benefit can be decisive. In Cour administrative d’appel de Douai, 14 June 2012, no. 11DA00200, the court examined a one-off payment of €55,928.84 from an employer-linked pension arrangement. The court found that the payment was funded by employer contributions and was not the return of capital previously alienated by the taxpayer. It held that the payment “constitue une pension imposable”, meaning that it was an assessable pension. The case is older and concerned the previous France–UK convention, but its method remains useful: the court looked at the scheme rules, who paid the contributions and the legal origin of the entitlement, not merely the fact that the money arrived in one instalment.
That decision also shows why a British resident in France should keep the pension deed or scheme rules, the contribution history and the provider’s payment explanation. If the document only says “tax-free cash”, it may answer the UK question while leaving the French classification unresolved. If the payment includes several components, ask the provider for a line-by-line statement. A tax authority or court will need to see which part is a pension, which part is a transfer, which part is a contribution refund, and which part is investment growth.
The amount should also be converted into euros for the French return using a defensible exchange-rate method for the relevant payment date. Keep the sterling amount, the conversion rate, the calculation and the bank statement together. Do not silently replace the provider’s gross figure with the net amount credited after UK withholding. A French return generally needs the taxable gross amount and a separate treatment of any foreign tax paid or withheld.
Finally, do not treat the French 10% pension abatement as a universal answer. Article 158 of the General Tax Code contains a 10% abatement for pensions and retirement benefits, but its current text contains specific rules for capital-form retirement benefits and for parts connected with certain French retirement products. The fact that a UK receipt is 25% tax-free under UK law does not itself establish that the French 10% abatement, the 7.5% option or any other French mechanism applies to every pound received.
B. What the France–UK treaty changes, and what it does not
After Brexit, the relevant France–UK income-tax convention remains the treaty signed in London on 19 June 2008 and published in France by Decree no. 2010-20 of 7 January 2010. The treaty is not a general exemption from French tax. It allocates taxing rights between the two states after the receipt has been classified under domestic law.
Article 18 deals with pensions. Its French text says that, subject to the public-function exception, “les pensions et autres rémunérations similaires payées à un résident d’un Etat contractant” “ne sont imposables que dans cet Etat”. The practical meaning is that a private or occupational pension paid to a treaty resident is generally taxable only in the state of residence. For a person who is resident in France under the treaty, that usually points towards France for a UK private pension or retirement lump sum.
The treaty analysis has two separate stages. First, establish treaty residence. A person may remain UK tax resident under UK domestic rules while being resident in France under the treaty’s tie-breaker. Article 4 of the convention looks at a permanent home, the closer personal and economic relations, habitual abode and, in some cases, nationality and an agreement between the competent authorities. Keep evidence of the French home, family life, work, health cover, bank activity and regular presence in each state if dual residence is possible.
Second, identify the pension category. Article 18 is not the only provision. Article 19 covers functions of government and contains special rules for public-service remuneration and pensions. A Civil Service pension, an armed-forces pension or another payment connected with public service should not be treated as a private workplace pension merely because the provider is based in the United Kingdom. The nationality exception in Article 19 can matter, as can the state or public body that paid the remuneration.
This classification is especially important for a lump sum. The word “lump sum” describes the payment format, not its treaty category. A PCLS drawn from a private workplace pension may be analysed with the pension article. A public-service pension may require Article 19. A payment that is actually a transfer, a redundancy benefit, a death benefit or a withdrawal of non-pension investment assets may fall under different provisions. The provider’s legal documents should be compared with the treaty wording.
The treaty also does not decide the French calculation method. Even if Article 18 gives France the taxing right, French domestic law decides whether the payment is taxed under the progressive scale, the quotient method or the 7.5% final flat-rate levy, if the statutory conditions are satisfied. Likewise, a UK tax deduction does not disappear simply because the treaty points to France. The correct remedy may be a claim for repayment from HM Revenue & Customs, a foreign-tax-credit analysis, or both, depending on the payment category and the treaty relief mechanism.
For UK tax administration, start with the official GOV.UK guidance on tax when living abroad and the published France–UK double-taxation convention. The UK guidance explains that the treaty determines where pension income is taxed and that HMRC may need to be told about the overseas residence. The treaty publication also contains the English text of the pension and government-service articles. Use the official text for the payment year, because a provider’s internal explanation may not cover the treaty’s public-service exception.
If the UK provider has withheld income tax even though the treaty assigns the pension to France, do not simply omit the receipt from the French return. Record the gross amount, the UK tax withheld and the treaty position. The UK government publishes a France Individual form and guidance for relief from UK income tax on relevant UK pensions and annuities. Whether that form is the correct route depends on the payment. A PCLS, UFPLS or other capital payment may require a more careful description than a recurring State Pension.
On the French side, the official impots.gouv.fr guidance on foreign-source income directs residents to the applicable treaty and the foreign-income declaration. A treaty-exempt item may still have to be disclosed when it is used to calculate an effective rate or other French tax. A treaty entry is not permission to leave the payment undocumented.
The safest conclusion is conditional. If you were treaty resident in France, the payment came from a private or occupational UK pension, and the provider’s documents show a retirement benefit, France will usually be the main taxing state under Article 18. That does not answer the rate or the declaration box. If the payment came from public service, included non-pension components or was received during a dual-residence year, obtain a written classification before relying on the treaty.
II. How to choose the French tax method and challenge a wrong assessment
A. The 7.5% option versus the quotient method
French law offers two important ways of dealing with a capital-form retirement payment, but they solve different problems. The first is the 7.5% option, formally a prélèvement forfaitaire libératoire, meaning a final flat-rate levy that releases the relevant income from ordinary income tax. The second is the système du quotient, or quotient method, which spreads the effect of an exceptional receipt in the calculation without removing the receipt from taxable income.
The 7.5% option is found in Article 163 bis II of the General Tax Code. The operative text refers to a request that is “expresse et irrévocable du bénéficiaire” and provides for a levy “au taux de 7,5 %”. The levy is applied after a 10% abatement to the relevant capital. The law also requires that the payment is not fractionated and that the beneficiary can show that the contributions made while building the rights, including employer contributions where applicable, were deductible from taxable income or related to exempt income in the state that had the right to tax it.
Those conditions must be tested against the actual UK pension. A payment being called a PCLS does not automatically prove that every statutory French condition is fulfilled. A provider statement should identify the rights drawn, the date and form of the payment, the contribution source and the tax treatment in the United Kingdom. If only part of the pot is paid, examine whether the payment is legally one non-fractionated retirement benefit or one instalment in a series. If contributions were made under different tax regimes, the analysis may need to separate the rights.
The French provision excludes certain categories, including specified French retirement savings products. That exclusion does not mean that every foreign pension is excluded, but it does mean that the provider’s label is not enough. Compare the UK scheme with the wording of Article 163 bis II and the linked provisions of Article 158. A written explanation should state why the scheme is within the legal category of a capital-form retirement benefit and why the contribution condition is met.
The 7.5% levy is not the same as paying 7.5% of the entire sterling amount. The base is the eligible capital after the statutory 10% abatement, and other taxes or social contributions may require separate analysis. For a hypothetical eligible capital of €40,000, the income-tax base under this method would be €36,000 and the income-tax calculation at 7.5% would be €2,700. That illustration does not decide eligibility, the exchange rate, social charges, the applicable year or the treatment of a UK deduction. It simply shows why a gross payment and a net bank credit should not be substituted for one another.
The Supreme Administrative Court, the Conseil d’État, considered the timing of this option in 14 June 2017, no. 397052. The court described the statutory choice as a possibility to apply “un prélèvement forfaitaire de 7,5 % libératoire de l’impôt sur le revenu”. It then held that the request could be made by a formal claim within the ordinary claims period even though the taxpayer had not made the request in the original return. The operative passage states: “la demande tendant au bénéfice du prélèvement forfaitaire libératoire peut être formée par le contribuable par voie de réclamation”. This is a valuable safeguard, but it is not a reason to delay: evidence can disappear, the provider may change systems and the deadline remains important.
The quotient method is different. Article 163-0 A of the General Tax Code applies to an exceptional income that is not normally received each year and exceeds the average of the net income used for the previous three years. Its calculation is described as “en ajoutant le quart du revenu exceptionnel net à son revenu net global imposable et en multipliant par quatre” the additional assessment. The mechanism reduces the effect of progressive tax brackets in the year of receipt. It does not convert the capital into exempt money.
The quotient route may be relevant when the 7.5% conditions are not met, when the payment is not eligible for the final levy, or when a comparison shows that progressive taxation is more favourable. Eligibility is not automatic simply because the amount is large. The payment must have the legal character of exceptional income and must be taxed under the progressive scale. A payment made in several planned instalments may raise a different question from a single retirement benefit.
In Conseil d’État, 28 September 2016, no. 384465, the court dealt with arrears of pension and the quotient calculation. It noted that the arrears “avaient la nature non d’une indemnité mais d’un revenu imposable”, meaning that they were taxable income rather than compensation. The decision is useful for two reasons. First, it confirms that the label used by a taxpayer does not control the tax category. Second, it shows that the quotient calculation must follow the statutory formula and the rules for the net global income; it is not a general discretion to reduce the amount.
The official French tax page explains both routes in practical terms: a recipient of a capital retirement benefit may request the quotient system or opt for the 7.5% rate where the conditions are fulfilled. The choice should be made after comparing:
- the gross amount converted into euros;
- the 10% statutory abatement and any rule that prevents it from applying to a particular component;
- the household’s other taxable income in the year of receipt;
- the household’s net income over the three preceding years for the quotient test;
- the marginal effect of the progressive scale;
- the legal character of the UK payment and whether it was fractionated;
- the UK tax actually withheld and the treaty relief available; and
- any social-contribution consequences, which are separate from the income-tax calculation.
Do not tick both routes casually. The 7.5% request is expressly irrevocable under Article 163 bis II. A return should make the chosen treatment visible and should not report the same capital both as ordinary pension income and as a separate capital payment. If the payment contained multiple legally distinct components, a single election over the entire bank credit may be wrong.
B. What to declare, what to keep, and how to appeal
Start with a document pack assembled before the French return is filed. It should contain the pension scheme name and rules, the provider’s gross payment statement, the date funds became available, the tax-free and taxable split shown under UK law, the amount and nature of any UK withholding, the contribution history, and the bank statement showing receipt. Add proof of French residence and, when relevant, proof of the treaty tie-breaker analysis. A tax certificate issued by the provider is useful, but it is not a substitute for the scheme rules where the payment is unusual.
The French forms should follow the classification. A French resident generally reports foreign-source income through the foreign-income process, commonly using form 2047 together with the relevant 2042 or 2042-C return. The exact boxes depend on the year and the nature of the payment. The official tax administration page states that ordinary pensions are pre-filled in boxes such as 1AS or 1BS, while capital-form retirement benefits and the 7.5% or quotient routes require different treatment. For the 7.5% route, check the current instructions and the boxes designated for the flat-rate capital benefit, often identified in the instructions as 1AT or 1BT. For the quotient route, the instructions may refer to the exceptional-income box, including 0XX. Never copy a number from an old year without checking the current form.
The key operational rule is consistency. The amount declared in euros, the category entered on form 2047, the amount shown on the main income return and the claim for any foreign tax must tell the same story. Do not put the full payment in the ordinary pension boxes and then also claim the 7.5% treatment for the same amount. Do not report only the 75% UK-taxable element if the French rule treats the whole retirement benefit as capital income subject to its own abatement and method. Preserve the calculation as a PDF or spreadsheet so the figures can be reconstructed.
If the UK has withheld tax, ask whether the treaty requires repayment in the United Kingdom or permits a French credit. The answer depends on whether the payment is a private pension, a government pension, a payment from a scheme with a special status, or another form of income. Use the official UK treaty and France Individual materials, and retain the application, correspondence and repayment decision. A French tax return can still need to show the gross receipt even when the UK tax is later repaid.
The French Tax Code also contains a reporting rule in Article 170. The declaration is not a decorative form: it is the legal mechanism by which the taxpayer reports income and claims the relevant treatment. A request for the 7.5% route should be express. A note in a bank file or a verbal explanation to the provider does not replace the French election or a later formal claim.
If the French tax office applies the progressive scale when the 7.5% option was available, or refuses a quotient calculation, the first step is a réclamation, meaning a formal tax claim against the assessment. The claim should identify the assessment year, the notice or payment disputed, the exact amount, the legal basis, the requested correction and the supporting documents. State whether the issue is classification, treaty allocation, eligibility for Article 163 bis II, the quotient calculation, foreign tax or a simple reporting error.
The deadline is governed by Article R*196-1 of the French Tax Procedures Code. Its current wording says that claims “doivent être présentées à l’administration au plus tard le 31 décembre de la deuxième année suivant celle” identified by the assessment, payment or event. The precise starting point depends on the type of tax and the event being challenged. Calculate the deadline from the actual notice and payment records rather than from the day you first discovered the mistake.
The decision in Conseil d’État no. 397052 is particularly important for a missed election. It indicates that a taxpayer who omitted the capital retirement benefit or failed to request the final levy in the original return may still make the request by formal claim within the Article R*196-1 period, provided the statutory conditions are satisfied. The case does not remove the need to declare income and does not create eligibility where the payment does not qualify. It gives a procedural route to correct the method.
If the tax office sends a proposal to adjust the return, the procedure is different from a voluntary claim. Article L57 of the Tax Procedures Code requires that the administration’s proposal is “motivée de manière à lui permettre de formuler ses observations ou de faire connaître son acceptation”. In other words, the proposal must explain the basis of the adjustment so that the taxpayer can respond. The same article provides for a 30-day extension when the taxpayer requests it before the response deadline. Make that request in writing and keep proof of delivery.
An effective response to a French adjustment should follow the legal sequence:
- identify the UK payment precisely, with the provider’s wording and the payment date;
- state the French domestic category under Articles 79, 158 and, where relevant, 163 bis II or 163-0 A;
- apply the France–UK treaty after the domestic qualification, distinguishing Article 18 pensions from Article 19 public-service payments;
- show the euro conversion and the tax computation line by line;
- explain the chosen return boxes and remove any duplicate reporting;
- deal separately with UK withholding and the requested relief or repayment; and
- attach the documents that prove each factual statement.
The order matters. In CAA Douai no. 11DA00200, the court first identified the payment as a pension under French domestic law and then considered the treaty. In Conseil d’État no. 384465, the court examined the legal nature of the pension arrears before applying the quotient rules. A response that starts and ends with “the UK called it tax-free” skips the decisive legal questions.
If the claim is rejected, review the rejection notice and the available administrative and court routes. The taxpayer may need to take the dispute to the competent administrative court within the applicable time limit. The file should already contain the tax return, the notice, the claim, the tax office’s response, the provider documents, the treaty residence evidence and the calculation. A late appeal cannot usually be repaired by producing a better explanation after the procedural deadline has passed.
The same discipline applies when the payment occurred in an earlier year. An old payment may still be within the claims period, but the law, tax forms, treaty practice and provider records must be checked for that year. Do not assume that a later French form or a later version of Article 163 bis can be applied retrospectively. Identify the law in force on the date of receipt and on the year of assessment, then check the transitional rules if any.
Conclusion
A UK pension lump sum received by a British resident in France after Brexit has three separate layers: the UK description of the payment, the French domestic tax category and the treaty allocation of the taxing right. The phrase “25% tax-free cash” answers only the first layer. Under French law, a capital-form retirement benefit can remain reportable. A private or occupational pension will often point to France under Article 18 of the France–UK treaty, while a public-service pension may require Article 19.
The practical decision is usually between the French 7.5% final levy and the quotient method, but neither should be selected from the bank statement alone. Check whether the payment was non-fractionated, whether the contribution condition is proved, whether the receipt is exceptional income, and whether the payment has been split into legally different components. Keep the provider’s documents, make the French declaration consistent, and address any UK withholding separately.
If the return was filed using the wrong method, the issue may still be repairable. Conseil d’État no. 397052 confirms that a qualifying taxpayer can request the 7.5% treatment by formal claim within the statutory claims period. Article R*196-1 supplies the deadline framework, while Article L57 governs the response to a proposed adjustment. A prompt, documented claim is stronger than a general statement that the money was “tax-free” in Britain.
