A UK life-insurance payout can look straightforward when a British family is dealing with a death: the insurer identifies the beneficiary, releases the money and the beneficiary moves on. For a British person living in France, however, the payment can raise several separate legal questions. The contract may be governed by UK documents, the deceased may have been tax resident in France, the beneficiary may live in France, and both countries may examine the same death benefit under different rules.

The first distinction is fundamental. French civil law may treat the benefit as outside the deceased’s ordinary estate, while French tax law can still impose a transfer levy on all or part of the amount. The result depends on the policy’s legal nature, the identity and residence of the deceased and beneficiary, the dates and ages at which premiums were paid, the family structure, the UK Inheritance Tax position and the France–UK convention. A payment labelled “life insurance” in the United Kingdom is not automatically a French assurance-vie, meaning a French life-insurance investment contract.

This guide sets out a practical route for a British reader: identify the policy, determine the French regime, prepare the declaration, coordinate the UK position, and preserve a claim for treaty relief or repayment. It focuses on the person and the death benefit, not on buying French property or setting up a company. The rules below are a framework for deciding what must be checked promptly; the policy documents and the deceased’s complete tax history remain decisive.

I. How is a UK life-insurance payout taxed in France after a death?

A. Is the payout outside the French estate, and what does the policy actually contain?

Start by identifying the people and the money in the contract. The souscripteur is the person who took out the policy and paid the premiums. The assuré is the life on which the payment depends. The bénéficiaire is the person or organisation entitled to receive the death benefit. The premiums are the payments made during the life of the contract. A UK policy may also involve a trustee, a nominee, an assignment, a joint policyholder or a separate policy owner. Those details can change who is legally entitled to the money and which country’s rules need to be examined.

For a French-law life-insurance contract, Article L. 132-12 of the French Insurance Code states: « Le capital ou la rente stipulés payables lors du décès de l’assuré à un bénéficiaire déterminé ou à ses héritiers ne font pas partie de la succession de l’assuré. Le bénéficiaire, quelles que soient la forme et la date de sa désignation, est réputé y avoir eu seul droit à partir du jour du contrat, même si son acceptation est postérieure à la mort de l’assuré. » In English, the statutory starting point is that capital payable on death to an identified beneficiary does not form part of the deceased’s civil estate, and the beneficiary’s entitlement is treated as arising from the contract. That is a civil-law rule about the route by which the payment passes; it is not a promise that no French tax is due.

The same distinction matters for a British policy. A UK “life insurance” product may be a pure protection policy, a policy attached to an investment, a pension-related death benefit or an arrangement held through a trust. The French authorities and a French court may need to understand its substance rather than rely on the marketing label. Request the full policy wording, schedule, beneficiary clause, assignment history, premium ledger, benefit calculation and the insurer’s explanation of why the payment is being made. Ask whether the amount is a fixed sum assured, the policy’s surrender value, an investment account value, a pension death benefit or a mixture of these.

Check the beneficiary clause word by word. A named child, spouse, civil partner, charity, trust or “estate” beneficiary may lead to different civil and tax consequences. “The estate” is not the same as an individual named beneficiary. A clause may also contain a first beneficiary and substitute beneficiaries. If the named beneficiary died first, declined the benefit or had accepted the policy during the policyholder’s lifetime, the payment route can change. The insurer’s letter should therefore be compared with the contract, the death certificate and any later beneficiary designation.

Article L. 132-12 does not answer every family dispute. Article L. 132-13 of the French Insurance Code provides that the capital payable to a determined beneficiary is not subject to the ordinary rules of bringing gifts into the estate or reducing gifts that infringe protected heirs’ rights. It then makes an exception for premiums that were “manifestement exagérées eu égard” to the policyholder’s means, meaning manifestly excessive in view of that person’s financial capacity. A court can therefore be asked to examine the premiums, even when the insurer has paid the beneficiary under the clause.

The French concept of the réserve héréditaire is the protected share of an estate that the law preserves for certain heirs who accept the succession. Article 912 of the Civil Code defines it in these terms: « La réserve héréditaire est la part des biens et droits successoraux dont la loi assure la dévolution libre de charges à certains héritiers dits réservataires, s’ils sont appelés à la succession et s’ils l’acceptent. » Article 913 of the Civil Code sets out the ordinary limits on lifetime gifts and testamentary dispositions by reference to the number of children. Those provisions help explain why a child may challenge a payment, but they do not make every large premium excessive.

Two Cour de cassation decisions obtained and checked during the preparation of this article are especially useful. In its decision of 19 March 2014, first civil chamber, appeal no. 13-12.076, the Court used this wording: « Attendu, selon ce texte, que les primes versées par le souscripteur d’assurance-vie ne sont rapportables à la succession que si elles présentent un caractère manifestement exagéré eu égard aux facultés du souscripteur ; qu’un tel caractère s’apprécie au moment du versement, au regard de l’âge, des situations patrimoniale et familiale du souscripteur, ainsi que de l’utilité du contrat pour celui-ci ; » The decision is available on the official Cour de cassation record for no. 13-12.076. The practical lesson is that a percentage of assets alone does not settle the issue: the court must examine the utility of the contract as well as age, financial circumstances and family circumstances at the time of each payment.

In its published Bulletin decision of 19 December 2024, second civil chamber, appeal no. 23-19.110, the Court repeated the rule in a case involving a large payment to a charity: « Selon ce texte, les primes versées par le souscripteur d’un contrat d’assurance sur la vie ne sont rapportables à la succession que si elles présentent un caractère manifestement exagéré eu égard aux facultés du souscripteur, un tel caractère s’appréciant au moment du versement, au regard de l’âge, des situations patrimoniale et familiale du souscripteur ainsi que de l’utilité du contrat pour celui-ci. » The official decision no. 23-19.110 also shows why an heir should not rely only on an argument that the payment reduced the reserved share. The Court held that using the infringement of that share as a substitute for the statutory assessment was an incorrect legal approach.

That does not mean that an heir’s position is hopeless. Evidence can include the policyholder’s age at each premium, health and life expectancy as understood at the time, income, liquid assets, debts, property, regular expenditure, prior investments, purpose of the policy, need for protection, family relationships and the proportion of the overall wealth committed to the contract. A premium paid to protect a dependent partner may be assessed differently from a last-minute transfer that emptied the policyholder’s available savings. The question is factual and payment-by-payment, not a mechanical comparison with a single percentage.

There is also a timing point. The civil challenge and the tax declaration are different tracks. A beneficiary should not simply omit the policy from the estate file because a relative may challenge it. Conversely, a family member who thinks the premiums were excessive should not assume that a tax payment resolves the civil dispute. Preserve the insurer’s communications, the original policy, premium evidence and the deceased’s financial records before documents disappear or accounts are closed.

A useful first file contains five items: the complete policy, every beneficiary amendment, the premium and value history, the death certificate and a family tree showing the relationship between the deceased and each beneficiary. Add the deceased’s French and UK addresses, tax numbers, wills, marriage or civil-partnership documents, evidence of any trust or assignment, and correspondence from the insurer. A French translation may be required for a UK document, but keep the original and a certified translation together so that dates and legal expressions can be compared.

B. Which French tax regime applies: Article 757 B, Article 990 I, or ordinary succession duty?

Once the policy has been identified, determine whether France has a taxing connection. The territorial rule is in Article 750 ter of the French General Tax Code. The current text begins: « Sont soumis aux droits de mutation à titre gratuit : 1° Les biens meubles et immeubles situés en France ou hors de France, et notamment les fonds publics, parts d’intérêts, biens ou droits composant un trust défini à l’article 792-0 bis et produits qui y sont capitalisés, créances et généralement toutes les valeurs mobilières françaises ou étrangères de quelque nature qu’elles soient, lorsque le donateur ou le défunt a son domicile fiscal en France au sens de l’article 4 B ; » The English meaning is that a deceased person who has French tax domicile can bring worldwide assets within the French gift and inheritance-tax field, subject to the detailed statutory rules and any treaty.

Article 750 ter also contains rules for a deceased person who was not French tax resident and for a beneficiary who is French tax resident. In particular, the beneficiary-residence limb refers to at least six years of French tax residence during the ten years before receiving the property. That is not a shortcut to a final answer: the wording of the asset, the beneficiary’s exact residence history, the deceased’s domicile, the policy structure and the applicable treaty must all be checked. A British beneficiary who has recently moved to France may have a different result from someone who has lived there for most of the previous decade.

French life-insurance taxation then separates premiums paid before and after the policyholder’s seventieth birthday. The age must be determined on the date each premium was paid, not simply on the date the policy was opened and not on the date the insurer releases the death benefit. Ask for a transaction-level ledger. A policy opened at 62 may contain payments made at 69 and at 72, and those two groups can be treated differently.

Premiums paid after age 70: Article 757 B. Article 757 B of the General Tax Code says: « I.-Les sommes, rentes ou valeurs quelconques dues directement ou indirectement par un assureur, à raison du décès de l’assuré, donnent ouverture aux droits de mutation par décès suivant le degré de parenté existant entre le bénéficiaire à titre gratuit et l’assuré à concurrence de la fraction des primes versées après l’âge de soixante-dix ans. » It then provides a global allowance of €30,500 for the sums covered by the provision, across contracts connected with the same insured person. This is a tax rule about the relevant premiums; it should not be described as an automatic tax on the entire investment gain or as a separate €30,500 allowance for every beneficiary.

Under Article 757 B, the excess is generally taxed by reference to the relationship between the beneficiary and the insured under the succession-duty scale. The calculation can be affected by the contract’s history, the date of the policy, the identity of the beneficiary, prior transfers and the application of a treaty. A spouse or civil partner, child, distant relative and unrelated beneficiary do not begin from the same tax position. The insurer’s statement may show the amount it considers taxable, but it does not replace the French legal analysis.

Premiums paid before age 70: Article 990 I. Where the benefit does not fall within Article 757 B, Article 990 I of the General Tax Code provides a separate levy on sums, annuities or values due directly or indirectly from an insurer because of the insured’s death. The statutory mechanism includes a fixed allowance of €152,500 per beneficiary and, subject to the conditions and exceptions in the current text, a 20% rate up to €700,000 of the taxable share and a 31.25% rate above that threshold. The published article must be read in full because the scope, exemptions and statutory exceptions matter.

For a simple illustration only, if one beneficiary receives €300,000 within the Article 990 I regime and no special exemption, treaty adjustment or other policy issue changes the calculation, €152,500 would be removed first and €147,500 would remain in the first rate band. That produces a notional levy of €29,500 before any other factor. It is not a quote for a particular case. If several policies exist, the allowances and relationship between the contracts must be reviewed together, rather than calculated from a single insurer’s letter in isolation.

For Article 757 B, suppose the ledger shows €90,000 of premiums paid after age 70. The initial mathematical question would be the portion above the global €30,500 allowance, not the whole death benefit. The beneficiary relationship and the treaty may then determine the duty. If the policy has both pre-70 and post-70 payments, the ledger should keep those amounts separate and show the date, currency, payer and recipient of every transaction.

Do not assume that a UK life policy fits neatly into the French product vocabulary. France may need to decide whether the policy is economically and legally comparable to an assurance-vie, an insurance protection contract, a pension benefit or a trust-held right. The insurer’s residence, the insured’s identity, the policyholder’s rights, surrender rights, investment features and the route by which the benefit is paid can matter. The official impots.gouv.fr guidance on life-insurance premiums is a useful starting point, but it cannot determine the classification of an individual UK contract without its documents.

Tax domicile and civil domicile should also be kept separate. A person can have a home, family and bank accounts in France while the treaty analysis asks a more technical question about fiscal domicile. The date of the move, centre of vital interests, permanent home, employment or pension arrangements, and any competing UK connection may matter. A beneficiary’s French residence can also be relevant even where the deceased lived in the United Kingdom. Record the facts rather than relying on a broad statement such as “the deceased was British” or “the money came from a UK insurer”. Nationality by itself does not answer the French tax question.

Finally, distinguish the French charge from UK Inheritance Tax, or UK IHT. The United Kingdom may examine the deceased’s status, the policy, ownership and the overall estate under current UK rules. The official GOV.UK guidance for a death involving someone living outside the UK explains that an executor may need to consider foreign tax and possible treaty relief where both countries tax the same assets. A British national who has moved to France should not assume that French residence automatically removes every UK question, and a French tax assessment does not prove that no UK IHT is due.

II. How can a British beneficiary declare the payout and challenge double taxation?

A. What documents and deadlines protect the declaration and the treaty claim?

The safest approach is to open one cross-border file and prepare the French and UK records together. The French administration needs to see what was received, why it was received and how the taxable base was calculated. HM Revenue & Customs, the UK tax authority, may need the same evidence in a different format. A beneficiary should ask the insurer for a signed statement showing the policy number, policyholder, insured person, date of death, beneficiary, gross benefit, deductions, currency, exchange-rate method, premium dates, total premiums before and after age 70, and any tax already withheld.

Collect the death certificate, the policy schedule and full terms, all beneficiary forms, assignments, trust deeds, investment statements, premium receipts, bank statements showing payments, and the insurer’s final settlement letter. Add the deceased’s French tax returns, French tax number, proof of French residence, UK address history, UK tax records, pension or employment evidence, and any correspondence about domicile. If a UK executor or solicitor is administering the estate, obtain the grant, will, estate account and the UK IHT computation. If the beneficiary is a spouse, civil partner, child or more distant relative, include the civil-status documents that prove the relationship.

Translation should be planned, not improvised after an assessment. Keep the English original, identify the document and date, and obtain a reliable French translation of the clauses that matter: ownership, beneficiary, assignment, trust, premiums and payment. A translation that turns “policyholder” into “beneficiary”, or confuses “sum assured” with “surrender value”, can distort the tax analysis. If an authority asks for an apostille or a certified copy, comply with that specific request and retain proof of delivery.

The French declaration is not optional merely because the insurer has already paid. Article 800 of the General Tax Code states: « I. – Les héritiers, légataires ou donataires, leurs tuteurs ou curateurs, sont tenus de souscrire une déclaration détaillée. » In practical terms, an heir, legatee or beneficiary must provide a detailed declaration where the French rules require one. The policy should be disclosed to the notary and, where appropriate, to the French registration or tax service handling the death declaration. The exact form and supporting schedules depend on the estate and the tax regime; do not assume that an insurer’s summary is the complete declaration.

The ordinary timing rule is in Article 641 of the General Tax Code: « Les délais pour l’enregistrement des déclarations que les héritiers, donataires ou légataires ont à souscrire des biens à eux échus ou transmis par décès sont : De six mois, à compter du jour du décès, lorsque celui dont on recueille la succession est décédé en France métropolitaine; D’une année, dans tous les autres cas. » The location of the death and the applicable procedural category must be confirmed, but the message is clear: a cross-border beneficiary should calendar the deadline immediately. Waiting for the UK insurer or an overseas probate process can consume the French period.

Build a calculation schedule with separate lines for the civil benefit, pre-70 premiums, post-70 premiums, policy growth where relevant, existing allowances, beneficiary relationship, French tax already paid and any UK tax on the same asset. Add a second schedule for exchange rates. A UK policy is usually stated in pounds sterling, while a French declaration is made in euros. The conversion date and source should be documented, and rounding should be consistent between the declaration and any later claim.

On the UK side, review whether an IHT account is required and whether the policy is included in the deceased’s estate or otherwise relevant to the UK computation. The official HMRC IHT410 life-assurance and annuities form is a current source for the information HMRC may request about life assurance. It should be read with the wider IHT account and current guidance, particularly where the policy was written in trust, assigned, jointly owned or linked to a pension. The form is evidence of the UK reporting route; it is not a French tax form and does not decide the French classification.

Now test the France–UK convention. The bilateral inheritance-tax convention was signed on 21 June 1963 and published in France by Decree no. 64-789 of 27 July 1964 on Légifrance. It is an older instrument, and the UK’s current HMRC Inheritance Tax Manual guidance on the France convention explains that its articles address the situs of assets, the state that waives its claim in certain circumstances and relief where both countries tax. The manual also says that the convention covers UK IHT due on death and describes documentary evidence such as the French declaration and clearance certificate.

For a life-insurance payout, the treaty analysis is not a slogan such as “the UK policy is taxed only in the UK”. The team must identify the asset for treaty purposes, the deceased’s fiscal domicile under the convention, the policyholder’s rights, the beneficiary’s rights, the location or situs attributed to the benefit, and the tax actually imposed in each state. An insurer established in the United Kingdom is one fact; it is not necessarily the treaty answer. A trust, pension wrapper or assignment can change the analysis again.

The treaty file should therefore contain the UK IHT account or final calculation, proof of payment or discharge, the French declaration, the French assessment or clearance certificate, the policy and premium ledger, the tax residence evidence and a written schedule showing the same asset being compared in both countries. HMRC’s manual refers to a French form used to certify UK IHT in certain cases where credit is sought in France. Confirm the current form and signing route with HMRC or the relevant French tax service before filing; a certificate for a different asset or a provisional tax figure may not support a final credit.

A British beneficiary should never leave the treaty question until after the French limitation period has expired. Put the potential claim in writing to the notary and the relevant tax service, ask which authority must process it, and request a written position if the administration says the convention does not apply. Keep proof of every submission, attachment and acknowledgement. If the UK computation is not final, record that fact and ask how a provisional payment, guarantee or later adjustment should be handled.

B. How do you recover an overpayment, challenge an excessive premium finding, or use mutual agreement?

There are three different kinds of correction, and they should not be mixed. First, an administrative correction may be needed because the wrong French regime was used, the wrong age was recorded, an allowance was counted twice or a contract was omitted from a combined calculation. Secondly, a treaty claim may seek a waiver or credit because France and the United Kingdom taxed the same asset. Thirdly, a civil succession claim may argue that premiums were manifestly excessive and should be brought into the calculation of protected heirs’ rights. Each route has different evidence, recipients and deadlines.

If French tax is assessed, check the notice line by line. Compare the taxable amount with the insurer’s ledger and with the policy’s actual payment. Confirm whether the €30,500 global allowance under Article 757 B has been allocated across all relevant contracts for the same insured person. For an Article 990 I calculation, check the €152,500 allowance per beneficiary, the benefit attributed to each beneficiary and the rate band. Verify that the policy was not taxed as an ordinary estate asset when a specific regime applied, but also verify the opposite: a contract outside the ordinary French product category may not receive an allowance merely because it is called life insurance in English.

Check the residence rules under Article 750 ter separately from the policy rules. A French resident beneficiary may have a worldwide-asset exposure after the statutory six-of-ten-year test, while a non-resident beneficiary may be affected by the deceased’s French domicile or by French-situs property. The France–UK convention may then allocate or limit the taxing right. Create a short residence chronology with dates of arrival, departures, homes, tax returns and treaty-residence evidence. An assertion in a cover letter is weaker than a dated file.

If both countries have charged tax, calculate the overlap asset by asset. A credit is normally limited by the treaty and by the tax attributable to the same property; it is not a general refund of every tax paid anywhere in the estate. HMRC’s official manual explains that relief can involve credit and that credit for French duty should not exceed the UK tax due on the relevant asset. The French authority will need evidence that the UK tax is final, paid and connected to the same death benefit. A French tax receipt alone does not prove the UK amount, and a UK IHT receipt alone does not prove the French asset classification.

Consider payment and challenge together. Article 1701 of the General Tax Code states that death-transfer duties are paid before registration and that the taxpayer may seek restitution where appropriate; the text includes: « Nul ne peut en atténuer ni différer le paiement sous le prétexte de contestation sur la quotité, ni pour quelque autre motif que ce soit, sauf à se pourvoir en restitution s’il y a lieu. » In practice, a disputed calculation does not automatically suspend payment. Ask the tax service or adviser about the procedural route, security and any request for relief, rather than simply withholding the amount.

For a repayment or formal tax challenge, preserve the time limit. Article R*196-1 of the Book of Tax Procedures begins: « Pour être recevables, les réclamations relatives aux impôts autres que les impôts directs locaux et les taxes annexes à ces impôts, doivent être présentées à l’administration au plus tard le 31 décembre de la deuxième année suivant celle, selon le cas : » The correct branch depends on the nature of the tax, the assessment and the event that starts the period. Put in a protective claim before the deadline if the final treaty certificate is still being obtained, and then complete the evidence as the administration instructs.

A useful claim explains the result sought in one sentence: repayment of the excess French duty, application of treaty relief, correction of the taxable premium base or recognition of the correct beneficiary. It attaches a numbered bundle and a calculation table. It identifies every prior filing, payment date and assessment reference. It asks the administration to state which factual or legal point it rejects. A vague request that “the tax be reconsidered” makes it harder to know whether the problem is the French regime, territoriality, a treaty credit or arithmetic.

If the dispute concerns manifestly excessive premiums, build a different evidence bundle. Use the policyholder’s bank statements and investment records for the date of each payment, not only the value at death. Show income, pensions, debts, property, cash reserves, medical expenditure, dependants, prior investment objectives, policy benefits and the policyholder’s needs at the time. Explain whether the contract provided useful protection or liquidity. The 2014 and 2024 Cour de cassation decisions show that the analysis is not replaced by a single argument about the reserved share, the beneficiary being a third party or the size of the final payment.

The 2024 case is particularly important for a beneficiary facing a family challenge. The Court of cassation annulled the appeal decision because it had relied on a criterion that did not properly assess whether the premiums were manifestly excessive. That does not immunise a payment made in suspicious circumstances. It means that a court must apply the statutory test at the time of the premiums, considering age, financial and family circumstances and the usefulness of the contract. The beneficiary should preserve evidence supporting the policy’s purpose; the heir should preserve evidence showing why the payments were disproportionate and unnecessary.

Keep the tax and civil files separate even where the facts overlap. A tax authority’s acceptance of a declaration does not decide whether a premium was excessive under Article L. 132-13. A civil judgment about the amount brought into the succession does not necessarily recalculate a levy that was imposed under Article 757 B or Article 990 I. If a family claim is issued, notify the insurer and the notary promptly, check whether the insurer has paid the full amount, and obtain advice on the proper defendants and interim steps. Do not transfer, spend or distribute disputed funds as though the dispute had disappeared.

Consider mutual agreement only after the domestic calculations are clear. The treaty may provide an allocation rule or a credit, but the competent authorities need a defined case. The file should state the French tax, the UK tax, the asset each tax concerns, the legal reason both states claim it, the relief already granted and the relief requested. A mutual-agreement process is not a substitute for a timely French claim or a timely UK filing. Preserve both domestic deadlines while the authorities communicate.

Here are three patterns that regularly require different answers. If a French-resident British person dies holding a UK policy for an adult child, France may examine worldwide territoriality, the policy’s age-of-premium split and the child’s benefit; the United Kingdom may also examine IHT and the convention may be relevant. If a UK-resident person leaves a UK policy to a beneficiary who has lived in France for at least the statutory period, Article 750 ter may require a wider French territorial analysis even though the deceased lived abroad. If the policy was written in trust or assigned before death, the legal owner, the insured and the beneficiary may not be the same person, so the ordinary “UK payout to a child” description is incomplete.

The action list is short but time-sensitive: obtain the full policy, freeze the document trail, identify the beneficiary, split premiums by age and date, map French and UK residence, disclose the benefit through the correct route, calculate both tax systems, test the 1963 convention, submit any protective claim before the applicable deadline, and keep a record of the payment and clearance certificates. If an heir alleges excessive premiums, open a parallel civil file without delaying tax compliance.

Conclusion

A UK life-insurance payout received after a death is not answered by the words “outside the estate” or “taxed in the UK”. In France, the civil route under Article L. 132-12, the excessive-premium safeguard in Article L. 132-13, territoriality under Article 750 ter and the specific Article 757 B or Article 990 I regimes must be considered separately. The United Kingdom may impose or examine IHT, and the 1963 France–UK convention may provide an allocation rule or credit where both countries tax the same death benefit.

Before filing, ask five questions: what exactly is the UK policy; when and at what age were the premiums paid; where were the deceased and beneficiary tax resident; what tax has each country actually charged on the same asset; and which deadline protects a correction or treaty claim? A complete policy ledger, a dated residence chronology and a carefully evidenced calculation usually matter more than the label used by the insurer. If the facts are disputed, keep the tax declaration, treaty claim and succession challenge on their own procedural tracks.
