You live in Kent, let a cottage in the Dordogne, and open your French tax notice to find income tax charged at a flat 20 per cent from the first euro, while your French neighbours pay under a progressive scale that starts at zero. Many British owners assume it is a Brexit penalty or a calculation error. It is neither. Since before Brexit, France has applied a minimum rate (taux minimum) to the French-source income of persons who are not French tax-resident, and British non-residents fall squarely inside it. The good news is that the same statute offers an escape route: the average rate (taux moyen), which caps your French tax at the rate you would have paid if all your worldwide income had been taxable in France, with any excess refunded.<\/p>\n
This guide is written for a British reader who remains resident in the United Kingdom for tax purposes but receives French-source income: holiday-let rents, a French salary for cross-border work, a French pension paid for past activity in France, or capital gains on a French property. A non-resident (non-r\u00e9sident) is a person whose usual home, family life and economic centre remain outside France. Every French term below is explained when it first appears. The property purchase process itself and company creation sit outside this guide. What follows explains why the 20 per cent appears, how the average rate is calculated box by box, which documents prove your worldwide income, and how to challenge a refusal and fix the position for next year. All amounts use the 2025 assessment rules applied to 2024 income, the latest published bands at the time of writing.<\/p>\n
The starting point is never the rate. It is residence, because residence decides whether France taxes your worldwide income under the progressive scale or only your French-source income under the non-resident regime. France treats a person as tax-resident where any one of four connections exists: the foyer<\/em> (family home) is in France, the principal place of abode is in France, a professional activity is carried on in France, or the centre of economic interests is in France. These tests appear in Articles 4 A and 4 B of the Code g\u00e9n\u00e9ral des imp\u00f4ts<\/a> (French General Tax Code). Only one needs to be met. A British couple who keep a flat in Manchester but live eleven months a year in the Charente, work remotely from France and organise family life there will normally be French tax-resident even if they keep British passports and bank accounts. Where both countries claim residence, Article 4 of the France\u2013United Kingdom double tax treaty of 19 June 2008 decides through a tie-breaker: permanent home first, then centre of vital interests, then habitual abode, then nationality, then mutual agreement between the administrations. The full English treaty text is published by the British government in the France tax treaty documents<\/a>, and the French publication was made by decree, referenced on L\u00e9gifrance, the official French legal database<\/a>.<\/p>\n If your usual place of residence remains in Britain, the French tax office states the position plainly: “You are a non-resident for tax purposes if your usual place of residence is outside France. The tax obligations of non-residents differ according to whether they receive income from French sources or not.” That sentence comes from the official English-language page How to determine whether or not you are a resident of France for tax purposes<\/a>, held by the French tax administration. Non-residence does not mean exemption. It means France taxes only the income connected with France, listed in Article 164 A of the Code g\u00e9n\u00e9ral des imp\u00f4ts<\/a>, which covers income from French immovable property, business profits earned through a French establishment, wages for activity physically performed in France, pensions paid for past French activity, and gains on French property. Each category is then allocated between France and the United Kingdom by the treaty: Article 6 keeps immovable-property income taxable where the property sits, so Dordogne rents are taxable in France; Article 13 keeps gains on French immovable property taxable in France; Article 14 allows France to tax salaries for work physically done in France; Article 18 allocates most private pensions to the residence country but leaves pensions paid for past French employment or French government service taxable in France under specific paragraphs. Our general residence-treaty analysis in where UK retirement income is taxed after Brexit and how to declare it<\/a> and our residence-challenge method in how to challenge a French tax residence assessment as a UK resident<\/a> set out the classification steps in detail, and our rental-income guide in UK rental income in France after Brexit: tax forms, deadlines and social charges<\/a> covers the declaration of the rents themselves.<\/p>\n Salaries and pensions need a separate warning because a deduction at source (retenue \u00e0 la source) may already have been taken before the final assessment. Wages, pensions and annuities paid to non-residents fall under Article 182 A of the Code g\u00e9n\u00e9ral des imp\u00f4ts<\/a>, which imposes a withholding computed under its own bands, credited against the final income-tax liability calculated under Article 197 A. A British consultant who spends three months on a French site and is paid by a French establishment, or a retiree whose supplementary pension relates to a French career, can therefore see two lines on the French paperwork: the withholding already levied and the final tax after the return is processed. The withholding is not the final tax. It is an advance, and the average-rate claim described in Part II operates on the final liability, not on the withholding bands. Keep every payslip, pension statement and withholding certificate, because the Service des imp\u00f4ts des particuliers non-r\u00e9sidents (SIPNR), the dedicated non-resident tax office at Noisy-le-Grand, will ask for them when it checks the claim. The SIPNR’s English-language contact and claims routes are set out on the non-resident tax office contact page<\/a>.<\/p>\n Once France has isolated the French-source net taxable income of a non-resident, it computes the tax in two stages. First it applies the ordinary progressive scale to that French income alone, exactly as it would for a resident. Then it compares the resulting effective rate with the statutory minimum rate (taux minimum) in Article 197 A of the Code g\u00e9n\u00e9ral des imp\u00f4ts<\/a> and charges whichever is higher. The administration summarises the rule as follows: “The minimum tax rate is 20% for the portion of net taxable income below \u20ac29,579 and 30% for the portion exceeding this limit (for 2025, based on 2024 income).” That sentence is quoted from the official page Understanding your tax notice as a non-resident<\/a>. In plain terms, if the progressive scale on your French income alone produces an average burden of, say, 9 per cent, the office lifts it to 20 per cent. If the scale already produces 34 per cent because the French income is large, the minimum changes nothing. The mechanism therefore bites hardest on modest French incomes: a British owner with \u20ac12,000 of net rental profit from one g\u00eete pays roughly \u20ac2,400 under the minimum, while a French resident with the same \u20ac12,000 of total income and the standard personal allowance structure would pay far less. The 30 per cent slice above \u20ac29,579 mirrors the top of the resident scale and rarely changes the outcome for mid-range cases, but it matters for substantial French rents or large French salaries.<\/p>\n Two refinements soften the picture and must be checked before any average-rate claim. The first is the reduction for low tax (d\u00e9cote), a statutory rebate that wipes out or trims small liabilities, governed by Article 197 B of the Code g\u00e9n\u00e9ral des imp\u00f4ts<\/a>. The administration describes its non-resident use in these terms: “If 60% or more of your income is from French sources, you can ask for your French tax to be capped, as with the d\u00e9cote: 0% up to \u20ac3,444, 20% from \u20ac3,444 to \u20ac8,636, 12% from \u20ac8,636 to \u20ac20,329.” Those figures are the 2025 limits quoted on the same official notice page. A British landlord whose French rents represent almost all household income and whose liability is small should therefore verify whether the d\u00e9cote already removed the charge before building an average-rate file. The second refinement is the European Union Schumacker line of cases, named after the Court of Justice decision in case C-279\/93, which requires the source country to grant the personal and family advantages of a resident where the non-resident earns almost all taxable income there but cannot be taxed on worldwide income at home. France transposed that logic into its non-resident rules: “As a non-resident, you can benefit from the ‘Schumacker’ rule if you receive most of your income from France but your tax domicile is in another European Union Member State or in a State that has signed a non-discrimination clause with France.” Because the United Kingdom left the European Union, British claimants now rely on the treaty’s non-discrimination article, Article 24 of the 2008 treaty, rather than automatic Union membership, and must show that France is where the bulk of the taxable capacity sits. In practice the Schumacker route helps the British owner whose French rents are 75 or 80 per cent of household income and who can evidence that the United Kingdom cannot take personal circumstances into account; it helps far less where the French income is a small holiday-let surplus beside a full British salary, and that is precisely where the average-rate claim becomes the better tool.<\/p>\n A worked illustration makes the minimum concrete. Take Susan, 58, employed full-time in Leeds on \u00a338,000, who nets \u20ac10,000 of furnished-holiday profit from a Bergerac studio after the micro-BIC allowance or actual expenses. Taxed as a resident on \u20ac10,000 alone, the progressive scale would produce a low single-digit effective rate. As a non-resident, the office first computes that scale figure, then applies the 20 per cent minimum to the \u20ac10,000, yielding about \u20ac2,000 before social charges and before any withholding credit. The outcome feels disproportionate because it is: the minimum deliberately ignores the British salary that would, in a resident calculation, have pushed the marginal slice higher but also opened personal allowances and family-quotient effects. The average-rate mechanism in Part II corrects this by reintroducing the worldwide picture. Keep the assessment notice (avis d’imposition) with its detailed calculation insert, because the line showing the minimum-rate uplift is the exhibit that justifies the claim. Where the notice instead shows a d\u00e9cote already applied or a Schumacker benefit granted, the file must say so openly; asking for the same relief twice slows every subsequent step.<\/p>\n The average rate (taux moyen) is not a separate allowance. It is a ceiling: your French tax on French-source income cannot exceed the tax that the progressive scale would have produced if your worldwide income had all been taxable in France. The administration puts the procedure in one sentence: “To benefit from this average rate, you must report your worldwide income in box 8TM of tax return no. 2042 and complete form no. 2041 TM.” That instruction appears on the same official Understanding your tax notice<\/a> page. Form 2042 is the main French income-tax return (d\u00e9claration d’ensemble des revenus); box 8TM (case 8TM) is the worldwide-income box reserved for non-residents; form 2041 TM is the computation schedule where the worldwide total is broken down by category and the effective rate is derived. Every figure entered there must be net taxable income under French rules, not gross British receipts, which means converting sterling at the annual average rate published by the Bank of France or the rate accepted by the SIPNR, deducting French-recognised expenses, and classifying each item as the French schedule would: salaries, pensions, rental profits, investment income. A British P60 total cannot simply be copied across; it must be restated as French net taxable salary after the standard 10 per cent professional deduction or actual expenses, and British rental accounts must be restated under the French furnished or unfurnished rental categories with the same allowances claimed on the French side.<\/p>\n The arithmetic then runs in four steps that should be replicated on a covering schedule so the inspector can follow the claim without reconstructing it. First, total the French-source net taxable income, say \u20ac10,000 of rental profit. Second, total the worldwide net taxable income, say \u20ac10,000 of French profit plus \u20ac42,000 of restated British salary, giving \u20ac52,000. Third, apply the resident progressive scale with the correct family quotient (quotient familial), the mechanism that divides taxable income into shares (parts) according to household composition, to the \u20ac52,000 and divide the resulting tax by \u20ac52,000 to obtain the effective average rate, for example 14.6 per cent. Fourth, apply that 14.6 per cent to the \u20ac10,000 of French income, yielding \u20ac1,460, and compare it with the \u20ac2,000 charged under the 20 per cent minimum. The difference, \u20ac540, is the refund or reduction due. The family-quotient rules that drive the third step sit in Articles 193 to 197 of the Code g\u00e9n\u00e9ral des imp\u00f4ts<\/a>, and the personal-charge provisions that adjust the result, such as maintenance payments or disability uplifts, sit in the same chapter; a British household that omits a second part for a married couple or a half-part for a disabled child understates its own claim by inflating the effective rate. Where the worldwide total is modest, the average rate can fall to single digits and the refund becomes substantial; where the worldwide total is large, the average rate can exceed 20 per cent, in which case the claim changes nothing and should not be made, because it invites scrutiny for no gain.<\/p>\n Evidence decides the outcome more often than arithmetic. The SIPNR cannot verify British income from French databases, so it asks for the British documents that reconcile to the 8TM total: the P60 or final payslips, the P11D benefits statement, the self-assessment tax calculation (SA302) with the corresponding tax-year overview, pension P60s, bank statements showing rents received where British property income is included in the worldwide total, and the French return with its rental schedule. Each sterling figure should show the conversion rate used and the resulting euro amount, and the covering letter should map every 8TM line to its supporting exhibit. Returns by non-residents are filed to the SIPNR, and the administration confirms that “The SIPNR is able to process your requests and complaints (claims, average rate applications, treaty applications, etc.)”, with filing routes and deadlines on the non-resident portal<\/a> and the general return-filing guidance in English on service-public.fr: filing an income-tax return<\/a>. File within the published non-resident deadline shown in your online account (espace particulier) on impots.gouv.fr<\/a>, keep the acknowledgement of receipt, and tick 8TM every year: the option is annual, and a refund obtained for one year does not carry forward automatically. Common rejections trace to three errors that are easy to avoid: entering gross British pay without the French deductions, omitting a spouse’s British income from the worldwide total while claiming two shares, and forgetting form 2041 TM altogether so the office has a worldwide figure it cannot audit. A file that shows net figures, both spouses, every exhibit and the four-step calculation is normally processed without a uterine round of questions; a bare 8TM figure with no schedule is routinely set aside.<\/p>\n A refusal rarely arrives as a single word. It arrives as a notice that ignores the 8TM figure, a proposed adjustment (proposition de rectification) questioning the worldwide total, or a silent renewal of the 20 per cent minimum the following year. Each has a defined remedy, and the remedies run in a fixed order. Where the assessment has already issued, the first step is a formal claim (r\u00e9clamation contentieuse), the written request that asks the office to discharge or reduce the tax, filed with the SIPNR with the calculation schedule, the exhibits and the legal basis. Time limits for claims sit in the Livre des proc\u00e9dures fiscales<\/a> (French Tax Procedure Book), principally Articles R*196-1 and R190-1, which set the standard deadline at 31 December of the second year following the year of assessment, with service and calculation rules in the surrounding articles; the acknowledgement-of-receipt date governs. The claim should identify the assessment, state the worldwide total and the effective rate claimed, list the exhibits by number, cite Article 197 A of the Code g\u00e9n\u00e9ral des imp\u00f4ts<\/a> for the average-rate ceiling, and quantify the refund with interest for late payment (int\u00e9r\u00eats moratoires) where the statute allows. Where the office instead opens an audit exchange before assessing, reply within the stated period with the same reconciliation, and never let a request for British documents go unanswered: an unanswered request becomes a deemed rejection that is far harder to unwind on appeal. Keep every exchange inside the online messaging thread so the procedural record is complete.<\/p>\n If the SIPNR maintains the minimum, the dispute moves to the administrative court (tribunal administratif), the first-instance judge for tax cases, under the procedure in the Code de justice administrative<\/a> (Code of Administrative Justice), with the standard two-month appeal period running from the express rejection or from the implied rejection after six months without reply. The pleading should frame the average rate as a ceiling, not a favour: show the worldwide total, the scale computation with the correct number of shares, the effective rate, and the capped French liability, then show that the treaty supports the outcome. Two treaty arguments recur for British claimants. First, Article 24 on non-discrimination provides that nationals of one contracting state shall not be subjected in the other to taxation that is more burdensome than that imposed on nationals in the same circumstances; a minimum rate that systematically taxes modest French incomes of British non-residents more heavily than the same incomes of French residents invites that comparison, subject to the objective-difference defences the administration will raise. Second, the Schumacker comparison described in Part I supports cases where France holds most of the taxable capacity and the United Kingdom cannot reflect personal circumstances, which strengthens the claim for the d\u00e9cote or family-quotient effects alongside the average rate. Neither argument excuses a defective worldwide figure. Courts routinely uphold the minimum where the taxpayer declared worldwide income late, partially, or in gross terms the judge cannot reconcile, and annul or reduce where the schedule is coherent and evidenced. Ask for discharge of the excess, a penalty rebate where penalties were added to a good-faith filing error, and costs; join the withholding certificates under Article 182 A of the Code g\u00e9n\u00e9ral des imp\u00f4ts<\/a> so the court credits them against the capped liability rather than the uncapped minimum.<\/p>\n Parallel practical steps protect the household while the dispute runs. First, fix next year’s file at the same time as the claim: tick 8TM again, attach form 2041 TM, and align the provisional payments (acomptes) with the capped figure so the following notice does not repeat the overcharge. Second, coordinate the British side: French rental profits remain declarable in the United Kingdom with a foreign tax credit for the French tax actually and finally paid, which means any French refund must be reported to HMRC so the credit is recalculated; guidance on foreign income and double-tax relief is published by the British government in the foreign tax credit relief computation rules<\/a> and the France treaty documents<\/a>. Third, calendar the late-return penalties explained in our late-return penalty guide<\/a>, because a worldwide figure filed after the deadline weakens both the claim and any penalty appeal. A compact pre-filing checklist prevents most failures: residence position confirmed in writing; French income classified under Article 164 A of the Code g\u00e9n\u00e9ral des imp\u00f4ts<\/a>; withholding certificates collected; worldwide income restated net in euros with the conversion rate shown; both spouses included; 8TM ticked with form 2041 TM attached; effective-rate schedule appended; SIPNR acknowledgement saved; next-year acomptes adjusted. Households that run that list each spring turn the average rate from an annual gamble into a routine.<\/p>\n We offer a telephone consultation within 48 hours with a lawyer from the firm.<\/p>\n We can review your French assessment, recalculate your average rate from your British documents, and prepare the 8TM file or the claim for you.<\/p>\n 06 46 60 58 22<\/a> \u2014 Ma\u00eetre Reda Kohen<\/p>\n Contact the firm through the French website<\/a>.<\/p>\n The 20 per cent minimum is not a Brexit surcharge and it is not negotiable in the abstract. It is the statutory starting point of Article 197 A of the Code g\u00e9n\u00e9ral des imp\u00f4ts<\/a> for every non-resident, British or otherwise, applied after the progressive scale has been computed on French-source income alone. The statute then offers two correctives that fit different households: the d\u00e9cote and Schumacker route where France holds most of the income, and the average rate wherever a worldwide picture produces a lower effective burden. For the typical British owner with a French holiday let beside a full British salary, the average rate is the remedy that matters, because it reintroduces the salary the minimum deliberately ignores and caps the French charge at the worldwide effective rate. The price of that remedy is rigour: net restated figures, both spouses, converted euros, box 8TM with form 2041 TM, and a schedule the SIPNR can verify without asking twice.<\/p>\n Start this week by pulling last year’s avis with its calculation insert, restating the British income net in euros, and running the four-step comparison before the next deadline. If the minimum exceeds the average-rate liability, file the 8TM schedule or the formal claim under the Livre des proc\u00e9dures fiscales<\/a> without waiting, align next-year payments, and notify HMRC of any refund so the foreign tax credit stays correct.

A minimum-rate notice answered with a complete average-rate file is a recoverable overpayment.
