For a British person who has become tax resident in France after Brexit, a missed filing deadline is rarely just an administrative nuisance. The late annual French income-tax return, the omitted foreign-income schedule, an undisclosed UK account, treaty relief and a penalty notice are connected, but they are not the same legal problem. Each requires its own correction, evidence and deadline.<\/p>\n
This guide addresses the practical situation in which a British resident in France has failed to file, or has filed without, Form 2047, the French schedule for income received abroad. It explains what to send to the French tax administration, how UK interest, pensions and rental income should be mapped, and how to distinguish an online correction from a formal tax claim or a request for discretionary relief. The rules below must still be applied to the relevant tax year and to the precise income category.<\/p>\n
The safest response is prompt and document-led: establish French tax residence for the year, rebuild the figures in euros, file every required form, preserve proof of submission and then challenge only the part of the assessment or penalty that is legally wrong. The France\u2013UK tax treaty can prevent double taxation, but it does not remove the duty to report income or automatically cancel a surcharge for a late return.<\/p>\n
Start with residence, not nationality. Brexit changed the immigration position of British citizens, but it did not create a separate French income-tax regime for them. Under Article 4 A of the French General Tax Code<\/a>, a person whose tax domicile is in France is liable to French income tax on the whole of his or her income. The statutory sentence says: \u201cLes personnes qui ont en France leur domicile fiscal sont passibles de l’imp\u00f4t sur le revenu en raison de l’ensemble de leurs revenus.\u201d In practical English, French residence normally brings worldwide income into the French reporting analysis.<\/p>\n Article 4 B of the same Code<\/a> identifies the main domestic indicators: the household or principal place of stay in France, a professional activity in France, or the centre of economic interests in France. These are factual tests. A UK passport, a UK bank account, a retained UK home or a continuing UK National Insurance record does not decide the question on its own. Conversely, a French home, family life, work or the management of investments from France may matter even if money continues to arrive in a British account.<\/p>\n The France\u2013UK convention must then be checked if both countries treat you as resident. Its residence article contains treaty tie-breaker rules based on matters such as a permanent home, personal and economic relations, habitual abode and, where necessary, an agreement between the competent authorities. The official text is available in the published France\u2013UK double-tax convention of 19 June 2008<\/a>. A treaty conclusion that you are resident only in the UK can change the extent of French taxation, but it does not justify ignoring a French-source item or a form that the French administration specifically requires.<\/p>\n Once French residence is established, identify which return was late. Article 170 of the General Tax Code<\/a> requires a person liable to income tax to submit a detailed declaration of income, benefits, family circumstances and the other information needed to calculate the tax. The French administration\u2019s current Form 2047 page<\/a> describes the document as \u201cD\u00e9claration des revenus encaiss\u00e9s \u00e0 l’\u00e9tranger\u201d, meaning the declaration of income received abroad. It is an annex to the main return, not a substitute for Form 2042.<\/p>\n A British resident who received UK interest, dividends, a pension, rent, employment income, investment income or another foreign item must therefore build a complete return for the relevant calendar year. The normal process is to enter the foreign item on Form 2047, apply the appropriate classification and treaty method, then transfer the required total to Form 2042 or another relevant French return. The official 2026 Form 2047 notice<\/a> should be used for the year in question because boxes and instructions can change.<\/p>\n Do not treat the UK tax year as if it were the French tax year. French personal income tax is organised by calendar year. HM Revenue & Customs may give you figures for a period running from 6 April to 5 April, while France may require income received between 1 January and 31 December. Reconcile the statements by payment date and income type. If you moved during the year, record the date on which your home, work and ordinary life moved, then test the domestic and treaty position for that year. The date on a visa or the date you exchanged a driving licence may support the chronology, but neither document alone proves tax residence.<\/p>\n If the late return concerns your first year in France, our broader guide to a first French tax return after moving from the UK<\/a> can be used for the arrival-year questions. This article addresses the narrower and often more urgent problem: a return is missing or incomplete, Form 2047 was omitted, or the tax notice has been calculated without the relief that the treaty may provide.<\/p>\n A practical filing sequence is:<\/p>\n Filing late is still better than allowing the administration to reconstruct the position from third-party information or a later enquiry. A return showing no additional French tax may still be useful because it establishes the declared facts and the treaty analysis. It does not, however, create a universal exemption from late-filing consequences. The amount at risk depends on the rights assessed, the type of declaration, whether a formal notice was served and whether the administration alleges an intentional omission.<\/p>\n Classify each receipt before entering a figure. The phrase \u201cUK income\u201d is too broad for a treaty analysis. A bank\u2019s savings interest, a dividend, a private pension, a UK State Pension, a public-service pension, rent from a UK property and a capital gain can have different source rules and different credit calculations. A tax deduction or PAYE withholding in the UK does not tell the French administration which box to use or whether the same amount is relieved in France.<\/p>\n For UK bank interest, collect the account statement, gross interest, tax deducted, payment date, account holder and currency. The French return should normally start from the gross amount required by the applicable French category and then apply the treaty mechanism, rather than using only the net amount that reached your account. If the bank paid interest without UK withholding, that does not make the receipt non-taxable in France. If UK tax was withheld, preserve the certificate and check whether the France\u2013UK convention gives France a credit, gives the UK a taxing right, or requires a different treatment.<\/p>\n Dividends require a separate calculation because the treaty\u2019s dividend article and French domestic rules may produce a different credit method from ordinary interest. Do not assume that every foreign withholding tax can be entered as a French tax credit. The credit may be capped, may depend on the treaty article governing the income and may require evidence that the tax was finally borne. If a French tax notice refuses a dividend credit, that is a specific treaty and calculation dispute; it is not automatically the same as the late Form 2047 issue.<\/p>\n Pensions need the same care. Identify the scheme, the legal source of the payment, whether it is private or connected with government service, the country of residence at the payment date, any lump sum and any PAYE deduction. The France\u2013UK convention allocates different categories of pensions and public-service remuneration through different provisions. A P60, pension provider statement, HMRC calculation, scheme rules and residence evidence are more useful than a bank statement alone. The separate British Desk article on UK private pension PAYE can help with the UK repayment route, but the French return must still contain the gross amount and the French treaty position for the year.<\/p>\n UK rental income is normally analysed by reference to the property and the convention\u2019s immovable-property rules. The UK may tax rent from a UK property because the property is there. France may still require disclosure by a French resident and may use the income in the French calculation, with the relevant credit or exemption method. Keep the rental accounts, mortgage-interest information where relevant, management fees, UK tax computation and dates of receipts. Do not omit the rent from Form 2047 merely because the UK return was filed first or because the money stayed in a British account.<\/p>\n The form and the treaty also interact with the foreign-account declaration. Article 1649 A of the General Tax Code<\/a> requires individuals domiciled in France to declare, at the same time as the income tax return, the references of accounts opened, held, used or closed abroad. The account declaration is not a second income-tax calculation. It is a compliance statement about the account itself. An account can be reportable even if it generated no interest; a Form 2047 can be required even where the receipt went to an account that was correctly declared.<\/p>\n That distinction matters after Brexit because a British bank account may now be treated as an account abroad for French purposes. A correction to Form 2047 does not automatically correct Form 3916 or Form 3916-bis, and a late account form does not calculate missing interest. Make an inventory with the account number or identifying reference, opening and closing dates, account holder, joint-holder or beneficial capacity, and the forms already submitted. If a pension wrapper or insurance policy has a special status, record the legal product rather than relying on the provider\u2019s marketing name.<\/p>\n The treaty\u2019s double-tax article is a relief mechanism, not a filing shortcut. Article 24 of the published convention provides a method for France to take certain UK-taxable income into account and then grant a credit subject to conditions and limits. For some income, the credit corresponds to the French tax attributable to the income if the income is within the UK tax base. For other categories, the credit is tied to UK tax actually paid and is capped by the French tax attributable to the same income. The correct result depends on the income article, not on the fact that the payment originated from a UK institution.<\/p>\n The Conseil d\u2019\u00c9tat examined this treaty issue in its opinion of 12 February 2020, no. 435907, available on L\u00e9gifrance<\/a>. In the part dealing with the Article 24(3)(a)(i) condition, the decision states: \u201cEn revanche, cette condition n’exige pas que les revenus en cause aient \u00e9t\u00e9 soumis \u00e0 une imposition effective.\u201d The ruling explains that the relevant income had to be included in the UK tax base, while actual UK tax payment was not necessarily required for that particular treaty condition. This is powerful evidence in the right case, but it is not a blanket answer for every pension, interest or dividend. The income category, the treaty paragraph and the proof of UK declaration still have to match.<\/p>\n The UK side must be reconciled as well. HMRC\u2019s guidance on foreign income<\/a> explains that UK tax treatment depends on residence and the nature of the foreign income, while the government\u2019s living in France guidance<\/a> directs readers to the double-tax agreement where the same income may be taxed in both countries. A British resident in France should not create two inconsistent explanations: one return saying that an amount was never received, another saying it was exempt, and a third saying UK tax was paid. The best evidence file contains one chronology and one calculation, with the different relief requested in each country clearly identified.<\/p>\n Finally, separate a late declaration from a deliberate concealment allegation. Article 1729 of the General Tax Code<\/a> concerns inaccuracies or omissions in a declaration and provides higher majorations where a deliberate breach, abuse of law or fraudulent manoeuvres are established. Forgetting a foreign schedule after moving countries may be serious, but the label \u201cdeliberate\u201d is not automatic. The chronology, the prompt correction, the consistency of the UK and French filings and the quality of the explanation can all be relevant to the characterisation of the omission.<\/p>\n Choose the remedy by looking at the stage of the file. A correction is used to put the return right. A r\u00e9clamation contentieuse<\/em> is a formal tax claim challenging an assessment, calculation or refusal. A demande gracieuse<\/em> is a discretionary request for relief, usually directed at penalties or hardship rather than a legal disagreement about the principal tax. Using the wrong label can waste time and obscure the deadline.<\/p>\n If the online correction service is open and the return is available in your personal tax account, correct the relevant forms and retain the acknowledgement. For the 2026 correction campaign, the public guidance states that online corrections can be made until 30 November 2026; the current government notice<\/a> should be checked for the applicable year and service status. That window is a filing facility, not a promise that every surcharge disappears. Correct the income, the treaty boxes, the account annexes and the explanation, then check the resulting notice.<\/p>\n If the online service is closed, the first return was filed on paper, the foreign schedule is not available in the account, or the administration has already issued an assessment, send the missing or corrected documents to the relevant tax office and ask for written confirmation. The Service-Public explanation of correcting an income-tax return<\/a> distinguishes the online correction period from the later claim route. A secure message can be useful because it gives a timestamp, but download the full message and attachments. For a material assessment or a deadline close to expiry, use a method that proves receipt.<\/p>\n When the assessment itself is wrong, make a formal claim rather than merely uploading another schedule. The claim should identify the tax year, notice number, taxpayer number, disputed lines, corrected calculation and the precise relief requested. If the problem is a refused treaty credit, show the treaty article, the income classification, the French amount, the UK tax-base evidence and the arithmetic. If the problem is an amount that was never received, show the bank records, employer or pension statements and the reason the original figure was included.<\/p>\n The general deadline is important. Article R*196-1 of the Book of Tax Procedures<\/a>, in its version in force from 30 July 2026, provides that claims for taxes other than local direct taxes must normally reach the administration by 31 December of the second year following the relevant assessment, assessment notice, payment or event. That is a general rule, not a substitute for checking a special deadline. The date on the notice, the date of payment, a later correction, a withholding mechanism and the nature of the tax can change the analysis. Treat the shortest plausible deadline as the working deadline until the file is reviewed.<\/p>\n A claim does not necessarily stop collection. The French tax administration\u2019s international taxpayer guidance<\/a> explains the correction and claim routes and warns that a claim does not, by itself, suspend payment. If you dispute a sum that would cause immediate difficulty, expressly ask about a sursis de paiement<\/em>, meaning a suspension of payment, identify the undisputed amount and explain the security or payment position requested. Do not simply stop paying without a written procedural basis; collection action can create a second dispute.<\/p>\n A discretionary request is different. Under Article L.247 of the Book of Tax Procedures<\/a>, the administration may grant a total or partial remission of tax penalties when the penalties, and where relevant the tax to which they are added, are final. The provision also permits a transaction reducing non-final penalties in the conditions stated by the text. The official wording refers to \u201cDes remises totales ou partielles d’amendes fiscales ou de majorations d’imp\u00f4ts\u201d. A goodwill request can therefore be appropriate where the tax is accepted, the late filing resulted from a documented exceptional difficulty and the taxpayer has acted transparently. It is not a substitute for a legal claim where the assessment or treaty calculation is wrong.<\/p>\n Use both routes where necessary, but keep their purposes separate. For example, a letter may ask for cancellation of a surcharge because the return was in fact filed before the deadline, make a formal claim against an incorrect foreign-income calculation, and, in the alternative, request a discretionary remission of any penalty that remains. State which part is the principal legal claim and which part is the alternative request. This prevents the administration from treating a challenge to the tax as a mere request for leniency.<\/p>\n A useful heading for the formal letter is \u201cR\u00e9clamation contentieuse \u2013 imp\u00f4t sur le revenu \u2013 ann\u00e9e [year] \u2013 Form 2047 and France\u2013UK treaty\u201d. The body can remain in English if the recipient can process it, but a clear French subject line and the French form names make routing easier. Include:<\/p>\n Do not bury the correction in a long narrative about Brexit. The administration needs to see what was omitted, why it was omitted, what was filed in the UK, what France should assess, what credit or exemption is claimed and what amount remains payable. A precise schedule often resolves an error more quickly than a general assertion that the treaty prevents double taxation.<\/p>\n The penalty analysis starts with the notice, not with the percentage printed on the bill. Identify whether the administration has applied the late-declaration rules, an omission or insufficiency penalty, interest for late payment, an account-reporting penalty or more than one measure. Then locate the legal basis, the tax principal on which it was calculated and the dates used. A British resident should request clarification if the notice uses an unexplained abbreviation or combines a late Form 2042 with a late Form 2047.<\/p>\n The current Article 1728 of the General Tax Code<\/a> provides a 10% majoration in the absence of formal notice, or where the return is filed within thirty days after receipt of a formal notice requiring it. It provides 40% where the return is not filed within thirty days after that notice, and 80% in the specific hidden-activity situation described by the text. The operative words include \u201c10 % en l’absence de mise en demeure\u201d. The document received, the date of receipt and the filing date therefore matter. A late foreign-income annex cannot be assessed in the abstract without examining what was late and which notice was served.<\/p>\n Article 1728 also addresses the interaction between a late overall income return and late category declarations. Where several declarations are late and different rates are involved, the text provides for proportional application to the income-tax amount represented by each breach, subject to the rule stated for the higher rate. This is one reason to rebuild the filing history form by form. A calculation that applies the highest percentage to every amount without identifying the legal basis may be challengeable.<\/p>\n Interest is separate from the majoration. Article 1727 of the General Tax Code<\/a> states: \u201cLe taux de l’int\u00e9r\u00eat de retard est de 0,20 % par mois.\u201d The article also fixes the calculation rules, including the normal 1 July starting point for income tax assessed for a year and the point at which interest stops when Article 1728 applies. It provides a possible 50% reduction of late interest for a spontaneous rectifying return made before the administration\u2019s recovery period expires, subject to good faith and payment conditions. That reduction concerns interest; it is not an automatic cancellation of the 10% late-filing majoration.<\/p>\n Check whether the administration is alleging a simple late filing or a deliberate omission. The 40% and 80% rates in Article 1729<\/a> relate to inaccuracies or omissions with additional legal conditions. Explain the factual reason for the mistake: the move occurred mid-year, the UK statement used a different tax year, a pension provider corrected a certificate, a bank changed its reporting format, or the Form 2047 was misunderstood as optional because UK tax had already been paid. A credible explanation is not a defence to every tax due, but it can be material to deliberate characterisation and penalty quantum.<\/p>\n Two Conseil d\u2019\u00c9tat decisions give useful boundaries. In its decision of 8 March 2002, no. 224304, Conseil d\u2019\u00c9tat, 9th and 10th chambers sitting together<\/a>, the court held that the tax judge must review the facts and the characterisation selected by the administration. The decision says that the judge may maintain the rate, substitute a lower rate among those provided by the statute where legally justified, or leave only late interest where the taxpayer did not abstain from filing within the legal period. It also uses the phrase \u201cle juge dispose ainsi d’un pouvoir de pleine juridiction\u201d. The case concerned an earlier version of the text and does not give a free power to invent a rate, but it shows why the notice and filing chronology must be tested.<\/p>\n In its Section decision of 22 April 2005, no. 257254, Conseil d\u2019\u00c9tat, Section du Contentieux<\/a>, the court distinguished the late-return majoration from majorations for insufficiencies, inaccuracies or omissions. It accepted that both rules could apply to different aspects of a late and incomplete declaration, while holding that the combined majorations for the same rights could not exceed 80% under the provisions then considered. The present assessment must be checked against the current version of Articles 1727, 1728 and 1729, but the decision remains a warning against treating every foreign-income omission as one undifferentiated penalty.<\/p>\n For a treaty dispute, include evidence that maps to the specific Article 24 method. The 2020 Conseil d\u2019\u00c9tat opinion no. 435907 is particularly useful where France has granted, or refused, a credit linked to the income\u2019s inclusion in the UK tax base. Provide the UK return, HMRC calculation, tax certificate, payment statement and, if tax was nil, the document showing why the income was nevertheless within the UK tax base. The decision does not eliminate French reporting. It supports a carefully evidenced treaty calculation in the category to which the opinion applies.<\/p>\n If the administration has sent a proposition de rectification<\/em>, meaning a formal proposal to adjust the tax, answer the facts and the law within the stated period. Article L.57 of the Book of Tax Procedures<\/a> states that the proposal must be reasoned so that the taxpayer can make observations or accept it. It also states: \u201cL’administration adresse au contribuable une proposition de rectification qui doit \u00eatre motiv\u00e9e\u201d. Ask for the exact calculation, income category, treaty basis, evidence relied upon and penalty reasoning. Do not answer only that you were unaware of Form 2047; deal with every line.<\/p>\n The file should contain more than the documents that prove payment. Assemble a chronology folder and a calculation folder. The chronology folder should include the UK departure date, French arrival, leases, utility records, family location, work contracts, travel calendar, residence permit, tax-residence certificates, correspondence with both administrations and the date each filing was attempted. The calculation folder should include bank and pension statements, dividend vouchers, rental accounts, exchange-rate calculations, French forms, UK returns, HMRC notices, withholding certificates and a reconciliation between gross income and the amounts entered in each box.<\/p>\n For the account question, add the account-opening and closing evidence, statements showing whether the account was used, joint-holder details and every Form 3916 or 3916-bis already filed. A British resident may have several accounts that look similar but are legally different: current account, savings account, investment account, pension arrangement or insurance wrapper. Mark the status of each one. If an account form was omitted, correct it expressly instead of assuming that a Form 2047 submission will alert the administration to the omission in the desired way.<\/p>\n For the residence question, avoid a retrospective statement drafted only to reduce tax. Use contemporaneous material. A French tenancy agreement, household bills, school records, medical registration, professional activity, days spent in each country and the location of the family can support the factual analysis. A UK home and continuing UK ties should be disclosed and explained rather than hidden. If the treaty tie-breaker is relied upon, identify the permanent homes and centre of personal and economic relations for the relevant year, then explain why the conclusion follows.<\/p>\n For the penalty question, preserve the envelope, registered-mail tracking, secure-message timestamps, online account notices and the date shown on the formal notice. Article 1728 uses receipt of a mise en demeure<\/em>, meaning a formal demand to file, as a trigger for the higher rate. An undated telephone call and a formal notice received on a different date are not the same evidence. If the notice was sent to an old UK address after you had notified France of a French address, document the address history and the administration\u2019s records. That may affect the facts of service, although it does not automatically decide the underlying tax.<\/p>\n A request for remission should also be evidenced. Explain the exceptional event, the steps taken once it ended, the absence of concealment, the current financial effect of the penalty and the payment already made or proposed. Article L.247 distinguishes final penalties, which may be remitted, from non-final penalties that may be addressed by transaction. Ask for relief from the penalty and interest separately, and do not ask the administration to waive principal tax merely because the filing was late unless a separate legal error supports that request.<\/p>\n The France\u2013UK convention offers another route when the two administrations produce a result that is not treaty-compliant. Article 26, headed \u201cMutual agreement procedure\u201d, allows a resident who considers that measures by one or both states result, or will result, in taxation contrary to the convention to submit the case to the competent authority. The treaty states a three-year period from the first notification of the measure, or a six-year period from the end of the relevant fiscal year or assessment period, subject to the text. A mutual-agreement request should be treated as an additional treaty route, not as a reason to let the French domestic claim deadline expire.<\/p>\n The evidence should be assembled before the letter is sent, but filing should not be delayed for months while one document is being requested from a bank. Send the claim with a numbered provisional schedule, identify missing documents and update the administration when they arrive. If a deadline is close, protect the deadline with a clear claim and then complete the evidence. A perfect calculation submitted after the claim period may be less useful than a timely, intelligible claim that preserves the right to argue.<\/p>\n After submission, track four separate outcomes: acceptance of the corrected return, recalculation of the principal tax, cancellation or reduction of the majoration and correction of the treaty credit. A new notice may fix one but not all four. Compare the new notice with your schedule and verify that account-reporting forms have not been left outside the correction. If the answer is silent or rejects the treaty point without addressing the evidence, request the reasons and consider the next procedural step before the deadline.<\/p>\n A British resident in France who has missed a French filing deadline should not respond by sending a single late Form 2047 and hoping the France\u2013UK treaty will do the rest. Establish the residence position for the year, file the main return and the foreign-income schedule, separate income reporting from foreign-account reporting, and classify each UK receipt before applying treaty relief. Keep one euro calculation supported by statements, exchange-rate evidence and the UK filing position.<\/p>\n The penalty then requires its own analysis. Article 1728 addresses late filing, Article 1727 addresses interest, Article 1729 addresses certain inaccuracies and omissions, and Article L.247 offers a discretionary route in the circumstances described by the statute. A formal claim is needed when the tax or treaty credit is wrong; a remission request may be appropriate when the tax is accepted but the penalty is disproportionate to a documented exceptional difficulty. The deadlines under the Book of Tax Procedures and the treaty must be protected separately, and a claim does not automatically suspend collection.<\/p>\n The practical objective is a coherent record that both administrations can understand: when you became resident, what you received, where it was declared, what was taxed, which treaty paragraph applies and what amount remains due. Prompt correction, precise evidence and the correct procedural route give you the strongest basis to reduce an avoidable surcharge or challenge an assessment that does not reflect the law.<\/p>\n Telephone consultation within 48 hours with a lawyer from the firm.<\/p>\n We can review your late French return, Form 2047, treaty evidence and penalty notice within 48 hours.<\/p>\n\n
