A death in the United Kingdom can leave a British family facing a French inheritance tax return long after the funeral, particularly where the deceased owned a home in France, held a French bank account or left a beneficiary who had become resident there. Brexit did not remove the French filing obligation. It did, however, make it more important to separate three questions: which country can tax which asset, which deadline applies, and how a late filing should be regularised. A late return is not the same thing as a fraudulent return, and a French penalty notice should not be accepted without checking its legal basis and calculation.<\/p>\n
This guide concerns the French d\u00e9claration de succession<\/em>, meaning the inheritance tax return, after a death connected with the UK. It does not explain how to purchase French property, create a company or organise a commercial venture. The practical objective is narrower: identify the correct French office, reconstruct the estate at the date of death, file the missing information, calculate the exposure, and preserve any credit for UK inheritance tax. The rules below should be applied to the particular residence history, family relationship, assets and treaty position. A British executor, personal representative or beneficiary should act quickly when the French deadline has passed because interest may continue to run while the estate remains unreported.<\/p>\n The civil-law background is set out separately in our guide on whether a UK will works in France after Brexit<\/a>. That article concerns choice of law and the notary process; this one focuses on the late tax return, the penalty calculation and the evidence needed for relief.<\/p>\n The first question is not whether the family has already dealt with HM Revenue & Customs. It is whether French law requires a declaration. The French deadline is set by Article 641 of the French General Tax Code<\/a> (Code g\u00e9n\u00e9ral des imp\u00f4ts<\/em>, or CGI). Its operative rule states: \u201cDe six mois \u00e0 compter du jour du d\u00e9c\u00e8s, lorsque celui-ci est arriv\u00e9 en France\u201d and \u201cun an dans tous les autres cas.\u201d In practical English, a death in France normally gives six months; a death in the United Kingdom normally gives one year. The place of death is not the same as the deceased\u2019s domicile, nationality or the location of the French property.<\/p>\n For a death in England, Wales, Scotland or Northern Ireland, the usual French filing deadline is therefore twelve months from the date of death. Count from the date on the death certificate, not from the date on which probate was granted, the will was located, the property was valued or the French notary was instructed. A family that discovers the French asset during the second year should not wait for the UK estate to close before asking the French administration how to regularise the position. A filing made after the deadline is still useful: it gives the administration a declared estate from which tax, interest and any surcharge can be calculated and challenged.<\/p>\n The deadline does not answer the separate question of whether tax is due. Article 750 ter CGI<\/a> uses connecting factors that can produce French tax even when the deceased was British and the death occurred in Britain. In simplified form, France may look at the worldwide estate where the deceased was fiscally domiciled in France, or where a beneficiary was domiciled in France for at least six of the previous ten years, subject to the statutory conditions. Where neither of those French residence links applies, French-situated assets, such as French land or a French building, can still fall within the French charge. The residence history of each relevant person must be reconstructed rather than inferred from a British passport or a French address on one document.<\/p>\n A France\u2013UK estate is also affected by the tax convention and by domestic foreign-tax credit rules. The French administration\u2019s official page, \u201cWhen and where should an inheritance be declared?\u201d<\/a>, confirms the six-month and one-year distinction and identifies the forms and non-resident filing route. The UK side has its own timetable: GOV.UK states that inheritance tax is normally due by the end of the sixth month after the death<\/a>. That mismatch can mean that UK tax evidence is not final when the French return becomes due, or that the UK payment has been made before the French liability is fully assessed.<\/p>\n For a non-resident estate, the file will commonly be directed to the Service de la fiscalit\u00e9 des particuliers non-r\u00e9sidents<\/em> and the Recette des non-r\u00e9sidents<\/em>, which can be described as the French non-resident tax service and collection office. The exact office depends on the deceased\u2019s residence, the heirs\u2019 residence and the assets. Do not send a late return to an old local tax office merely because it dealt with a French income tax matter. Check the official impots.gouv.fr instructions for the address in force and keep proof of delivery. A notary may transmit the return or communicate with the administration, but the heirs, beneficiaries or legatees remain the people whose statutory filing and payment position must be understood.<\/p>\n The best first letter is short and factual. It should give the deceased\u2019s full name, date and place of death, last address, French tax number if known, the French asset, the date on which the family became aware of it, the reason for the delay, the identity of the persons entitled to the estate and the expected date of the complete filing. Ask the office to confirm the competent service, the forms required and the calculation date for interest. This is not a substitute for the return, but it creates a contemporaneous explanation of the delay and prevents a silent file from becoming harder to defend.<\/p>\n The French return is an estate snapshot at the date of death. The working file should therefore be built around that date, not around the later sale of a French property or a later bank balance. Start with the death certificate, the will and any codicil, the grant or equivalent UK probate documents, the family tree, marriage or civil-partnership evidence, and documents proving the relationship between the deceased and each beneficiary. Obtain certified translations where the French notary or administration requires them. A translation should make names, dates and addresses consistent across the British and French documents.<\/p>\n Then assemble an asset-and-liability schedule. For French real estate, include the title deed, address, ownership proportions, valuation at the date of death, mortgage balance and evidence of any life-interest or usufruit<\/em>. Usufruit is the French right to use an asset or receive its income while another person holds the underlying ownership. For bank and investment accounts, obtain statements at death and identify whether the account was individual, joint, held through a nominee or connected with a trust. Include shares, insurance policies, loans, unpaid bills and funeral liabilities only where the French rules permit them to be deducted and the evidence supports the deduction. A later market sale is useful evidence but does not automatically replace the date-of-death valuation.<\/p>\n The main forms are identified by the French tax administration according to the estate. The official instructions refer to form 2705 for the succession declaration, form 2705-S for certain supplementary information and form 2706 for the list of gifts or donations made during the relevant period. The exact pack can change with the family structure, foreign assets and whether a notary is filing electronically. Use the current forms linked from the official impots.gouv.fr contact and forms route<\/a>, and do not recycle a blank form downloaded years earlier. A return that omits a French asset, beneficiary or earlier lifetime gift can create a second problem even if the first late filing is accepted.<\/p>\n Article 800 CGI<\/a> is the statutory starting point for the declaration duty. Its practical effect is that heirs, donataries and legatees must provide a detailed declaration when the conditions for the succession declaration are met, subject to the exemptions and thresholds in the text. The responsibility does not disappear because the estate is administered in the UK. If several beneficiaries are involved, agree who will provide the signed information and who will pay any tax, but preserve written authority and a copy of the complete filing for every person affected.<\/p>\n There is a difference between the civil work of administering an estate and the tax work of making a French return. A French notaire, meaning a public officer with responsibility for many French conveyancing and succession instruments, can calculate, prepare and submit a return. The notaire cannot safely certify a value that the family has not evidenced. If the only French asset is a house, the estate may still require a wider analysis of residence, life insurance, a UK pension, a trust, lifetime gifts and the beneficiary\u2019s French residence. A late filing should be accompanied by a schedule showing what is known, what is being obtained and what has been estimated, rather than by unexplained round numbers.<\/p>\n International estates also produce documents that prove authority but do not necessarily transfer money. In First Civil Chamber, 13 April 2022, no. 20-23.530<\/a>, the Cour de cassation described the European Certificate of Succession as having \u201cune efficacit\u00e9 probatoire, mais ne constitue pas un titre ex\u00e9cutoire\u201d: it has evidential effect but is not an enforceable title. The decision matters when a French bank or institution asks for a certificate before releasing funds. It does not excuse a late declaration. Put the certificate, will, probate evidence and identity documents in the tax file, but ask the bank and the notary what additional proof they require.<\/p>\n Jurisdictional questions can also affect the practical route. In First Civil Chamber, 21 September 2022, no. 19-15.438<\/a>, the Cour de cassation dealt with an international succession involving a deceased person who had lived in the United Kingdom, French nationality and property in France. The decision illustrates why a French asset, nationality and habitual residence must be mapped separately when a dispute reaches a court. It is not a general answer that every UK estate belongs before a French court, but it is a warning against allowing a notary or beneficiary disagreement to delay the tax return indefinitely.<\/p>\n The will itself is another separate issue. Article 1000 of the French Civil Code<\/a> addresses the formalities for a foreign will to be registered before it can be executed in relation to French assets. First Civil Chamber, 17 June 2009, no. 07-21.718<\/a>, held in the context of immovable succession that \u201cLe montant de la r\u00e9serve h\u00e9r\u00e9ditaire est d\u00e9termin\u00e9 par la loi successorale qui, s’agissant des successions immobili\u00e8res, est celle du lieu de situation de l’immeuble.\u201d The reserved portion is a civil-law entitlement, not an inheritance tax rate, but the civil position can change who must sign, what evidence is needed and how an asset should be valued. Filing first and litigating later is often safer than waiting for the family dispute to settle, provided the return identifies the uncertainty honestly.<\/p>\n The Court has also considered foreign succession law in First Civil Chamber, 4 July 2018, nos. 17-16.515 and 17-16.522<\/a>, and in First Civil Chamber, 27 September 2017, no. 16-13.151<\/a>. Those decisions are relevant when a British will, a foreign governing-law clause or a reserved-heir argument is raised. They do not turn a tax return into a civil-law opinion. Record the competing positions, ask the notary to state the assumption used for the declaration, and obtain separate advice if the dispute changes the taxable beneficiaries or the value of their rights.<\/p>\n For a UK trust or a trust-like arrangement, include the trust deed, letters of wishes if relevant, accounts, distributions and the date each beneficiary received value. In Commercial Chamber, 18 November 2020, no. 18-14.242<\/a>, the Court held that the taxable event connected with a trust distribution could occur when the assets were distributed to the final beneficiary, after the death. The point is fact-sensitive, but a family should not assume that a trust document found after the death is either irrelevant or automatically taxable on the date of death. Give the French adviser the complete chronology.<\/p>\n A late French succession return can produce several different amounts. The tax itself is calculated from the estate and each beneficiary\u2019s entitlement. Late-payment interest compensates the Treasury for the delay. A filing penalty or majoration<\/em>, meaning a statutory surcharge, penalises a failure to file or a failure to respond to a formal notice. A separate late-payment surcharge may apply in circumstances set out by the Code. These are not interchangeable labels. Ask for a calculation that identifies principal tax, interest, each percentage surcharge, the period used and every payment or credit already recorded.<\/p>\n Article 1727 CGI<\/a> governs late-payment interest. The current text provides for interest calculated by month and states the rate in the Code; for the period currently relevant to this article, the statutory rate is 0.20% per month. The starting point can depend on the kind of tax and whether a declaration was due, so do not calculate from the date on which a demand letter was received without checking the applicable paragraph. Interest can continue until the tax is paid, even while the family is discussing the correct valuation or a foreign-tax credit.<\/p>\n The calculation should be tested rather than copied. Check the date of death, the applicable one-year deadline for a UK death, the date the administration says the return was due, the date of any formal notice, the date of filing, the date each instalment was paid and whether the declared tax changed. A month in the statutory calculation is not necessarily the same as a simple day-by-day percentage. If a spreadsheet uses a daily rate without explaining the legal basis, ask for a revised statement.<\/p>\n Article 1728 CGI<\/a> sets out the principal declaration penalties. The ordinary framework includes a 10% increase in specified late-filing situations, a 40% increase when a declaration is not filed within the period after a formal notice, and an 80% increase for an occult activity. The article also contains special rules for declarations covered by Article 800, including a trigger linked to the expiry of certain six-month or twenty-four-month periods. A UK death normally has a one-year deadline under Article 641, so the administration\u2019s notice should be read carefully rather than assuming that every percentage starts on the same day.<\/p>\n A 10% amount is not proof of fraud. Nor is an 80% allegation something to ignore because the family eventually files. \u201cOccult activity\u201d is a legal category that requires more than an ordinary late return. The family should ask the administration to state whether it relies on ordinary lateness, failure to respond to a formal notice, concealment or a different provision. If the estate was disclosed in the UK, the French property appeared in a notarial file, or the family contacted the French service before being formally pursued, preserve those facts. They may not automatically cancel a statutory penalty, but they can be important to the legal classification and to a request for remission.<\/p>\n Article 1731 CGI<\/a> concerns a 5% surcharge in defined late-payment circumstances. The article also contains an important limitation for a late declaration accompanied by full payment. This is why a family should not add 5% mechanically to the 10% or 40% figures. Determine whether the return and payment were made together, whether the tax was assessed automatically, whether an instalment arrangement was accepted and whether another penalty provision takes priority. The notice should explain the legal article used; if it does not, request the basis in writing.<\/p>\n Interest and penalties may be corrected when the original estate values were wrong. A French house may have been appraised too high or too low, a mortgage may have been omitted, a life-interest calculation may have been ignored, or the beneficiary\u2019s residence may have been classified incorrectly. Correcting the principal can change the interest and the percentage amounts. Do not deliberately leave an inaccurate value in place simply because it lowers the first demand: an incomplete or false return can create a more serious dispute and may damage a later request for relief.<\/p>\n The administration\u2019s calculation must also be compared with payments made in the UK. HMRC explains on its Inheritance Tax: Double Taxation Relief<\/a> page that a convention can allocate taxing rights and that credit is limited by the tax attributable to the same asset or property. The UK guidance should be read with the France\u2013UK estate tax convention, not used as a substitute for it. A French officer may ask for the UK assessment, proof of payment, the asset allocation and evidence that the UK amount relates to property taxed in France.<\/p>\n There is a practical sequencing risk. UK inheritance tax is commonly due at the end of the sixth month, while the French declaration after a UK death is normally due within twelve months. The family may therefore pay HMRC before it files in France, or file in France while the UK tax is under appeal. Maintain a ledger separating UK principal, interest, penalties and professional fees. Only the part that qualifies under the treaty or the French Code can be used as a credit. A payment made to HMRC is not automatically a credit against every French asset.<\/p>\n The safest regularisation sequence is to file the declaration, attach the asset schedule and supporting evidence, pay the undisputed French amount or request an available arrangement, and then challenge the disputed interest or penalty with reasons. A family should not wait for perfect agreement about every foreign asset if the French office will accept a clearly marked provisional calculation followed by a supplementary declaration. Ask the office or notary to confirm whether a supplementary return is required and retain the original and every annex.<\/p>\n Explain the delay with evidence, not adjectives. A useful chronology may show the date of death, probate application, discovery of the French asset, requests to banks, delays in obtaining a valuation, translation dates, contact with the notary, contact with HMRC, the UK tax assessment and the French filing date. If the delay arose from a genuine legal or factual uncertainty, identify the question and show the steps taken to resolve it. If a family member ignored letters, say which letter was missed and what has now been done. A request that simply says \u201cwe did not know\u201d is weaker than a documented account of why the filing could not be completed earlier.<\/p>\n Ask for relief in the correct form. A demande gracieuse<\/em> is a request to the tax administration for discretionary relief, usually focused on penalties or interest and supported by good faith, hardship, prompt correction and payment. A r\u00e9clamation contentieuse<\/em> is a formal tax claim disputing the legal basis or amount of an assessment. The distinction matters: an appeal about the 12-month deadline, taxable residence or double-tax credit should not be presented only as a plea for kindness, while a request to reduce an admitted penalty should not be described as if the underlying tax calculation were wrong. The notice and its appeal instructions govern the available time limits.<\/p>\n Do not assume that a reduction designed for a rectifying declaration automatically applies to an initial late succession return. Article 1727 CGI<\/a> contains a rule concerning a spontaneous rectifying declaration in defined conditions, but the facts and timing must fit the text. The stronger immediate steps are usually full disclosure, a correct return, payment of the undisputed amount and a specific request that the administration apply the relevant statutory relief or waive a penalty because its legal conditions are not met. The family should keep proof that the request was sent before the deadline in the notice.<\/p>\n For a foreign-tax credit, start with the asset-by-asset comparison. Article 784 A CGI<\/a> states: \u201cDans les cas d\u00e9finis aux 1\u00b0 et 3\u00b0 de l’article 750 ter, le montant des droits de mutation \u00e0 titre gratuit acquitt\u00e9, le cas \u00e9ch\u00e9ant, hors de France est imputable sur l’imp\u00f4t exigible en France.\u201d It immediately limits the credit to the tax paid on movable and immovable property situated outside France. In plain language, the French calculation has to identify the French taxing connection and the foreign asset to which the UK tax relates. The statutory credit is not a general refund of the French bill.<\/p>\n The France\u2013UK convention can provide a more specific route where both countries tax the same estate or asset. The official convention material published through BOFiP<\/a> should be read with the current administration\u2019s instructions. HMRC\u2019s guidance on France explains that the French d\u00e9claration de succession<\/em> and the certificat d\u2019acquittement<\/em>, meaning the French certificate confirming inheritance tax paid, may be needed to support UK relief. The UK process may also require HMRC form 50. Obtain a written certificate or assessment showing the tax actually paid, not merely an adviser\u2019s estimate.<\/p>\n Article 784 A and the treaty do not eliminate the French filing duty. A family cannot usually say that the French return is unnecessary because the UK has already taxed the estate. The return is the document through which France identifies the assets, applies its own exemptions and rates, and calculates the amount against which a credit may be claimed. File the UK evidence as soon as it is available. If the UK tax is still under appeal, state that fact, provide the provisional figure and explain how a later amendment will be handled.<\/p>\n The credit calculation should separate French-situated and non-French assets. A French house may be taxed in France under the convention even where the deceased lived in Britain. A UK bank account may have a different treaty treatment. A pension, ISA, life policy, trust distribution or jointly owned asset may need its own classification. Use the gross value, deductible liabilities, beneficiary share and tax paid on the same asset as the calculation columns. Avoid allocating all UK inheritance tax pro rata across French property without a treaty analysis; that shortcut can understate French tax, overstate credit or produce an avoidable request for further information.<\/p>\n Payment arrangements should be discussed early where the tax is admitted but cash is tied up in a French house. The fact that the house cannot be sold until the succession paperwork is resolved does not automatically suspend interest. Ask the notary and the competent tax service whether deferred or instalment payment is available for the estate\u2019s asset profile, what security is required, and whether the application must be made with the return. Keep the payment request separate from the legal challenge to a penalty. A request for time to pay is not necessarily an admission that every amount demanded is correct.<\/p>\n When a bank has frozen a French account, obtain a written statement of the balance at death and ask what document will release the funds. If the family relies on a European Certificate of Succession, remember the distinction made in no. 20-23.530: evidential effect is not the same as an enforceable title. If the dispute concerns a foreign will and a French immovable, identify the governing-law issue separately from the tax calculation. The decisions in nos. 07-21.718, 17-16.515 and 17-16.522 show why the civil succession question can affect the tax file without answering it by itself.<\/p>\n Finally, protect the record. Send the complete return and annexes in a format that preserves the French accents in names and addresses. Keep the transmission receipt, the post office tracking, the notary\u2019s confirmation, the bank statements, the UK probate record, the HMRC assessment and proof of every payment. If the administration later issues a formal notice, compare it with the declared figures and respond within the stated period. If the heirs disagree, one beneficiary should not alter the asset schedule without notifying the others. A transparent correction is much easier to defend than several inconsistent versions sent by different family members.<\/p>\n A late French inheritance tax return after a UK death should be treated as a regularisation project with four immediate objectives: identify the one-year French deadline, file with the correct non-resident route, calculate interest and penalties from the exact statutory provisions, and preserve the treaty or domestic credit for UK inheritance tax. The French return remains necessary even when HMRC has already dealt with the estate. The family should separate tax residence, asset location, civil succession rights and payment evidence rather than treating \u201cBritish estate\u201d as a single legal category.<\/p>\n The most useful first bundle is the death certificate, will and probate evidence, family tree, date-of-death valuations, liabilities, French property and bank documents, UK inheritance tax assessment or payment proof, and a dated explanation of the delay. Submit the return or a documented request for the correct filing route promptly. Then test the calculation under Articles 1727, 1728 and 1731 CGI, claim any properly supported credit under Article 784 A or the France\u2013UK convention, and challenge an unsupported surcharge in the procedure stated on the notice. Acting quickly does not guarantee that every penalty disappears, but it gives the family the strongest factual and procedural position available.<\/p>\n Arrange a telephone consultation within 48 hours with a lawyer from our firm.<\/p>\n We can review the French succession return, penalty notice and double-tax evidence before you respond.<\/p>\n Call +33 6 46 60 58 22<\/a> or contact the firm<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":" What British executors and beneficiaries should do when a French inheritance tax return is late after a UK death: deadline, documents, penalties, treaty relief and filing steps.<\/p>\n","protected":false},"author":251031309,"featured_media":16542,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_kj_source_type":"","_kj_official_id":"","_kj_official_url":"","_kj_judilibre_id":"","_kj_jur":"","_kj_lieu":"","_kj_chambre":"","_kj_rg":"","_kj_date":"","activitypub_content_warning":"","activitypub_content_visibility":"","activitypub_max_image_attachments":4,"activitypub_interaction_policy_quote":"anyone","activitypub_status":"federated","footnotes":""},"categories":[80312,80314],"tags":[],"class_list":["post-2098736","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-british-desk","category-decryptage"],"yoast_head":"\nI.
