From a cottage in Kent you now own a stone house in the Dordogne, a flat in Paris or a villa near Nice, and every autumn the same envelopes arrive from the French tax office. The amounts look unfamiliar, the labels are in French, and since Brexit friends keep telling you that the rules have changed for Britons. The core of French local property taxation has not changed with Brexit: if you own bricks and mortar in France you pay the same annual taxes as a French owner of the same property. What Brexit did change is your residence status, your reporting route and the way you challenge a mistake from abroad. This guide explains, in English with every French term defined, the three bills that matter for British owners after Brexit: the taxe fonciere (annual land and buildings tax paid by the owner), the taxe d’habitation sur les residences secondaires (council-type tax now kept only on second homes and furnished premises, with a possible local surcharge), and the impot sur la fortune immobiliere known as IFI (annual wealth tax on net property assets above 1.3 million euros). It then sets out how to check your assessment, how to file the compulsory prior complaint called a reclamation contentieuse, and how to take the case to the right court if the tax office says no. The law is stated as it stood on 26 September 2026, with the exact wording of the statutes quoted throughout.
I. What You Pay Each Year on Your French House: Taxe Fonciere, Second-Home Taxe d’Habitation and IFI
A. Taxe Fonciere and Taxe d’Habitation on Second Homes: Who Pays and How the 5% to 60% Surcharge Works
The taxe fonciere sur les proprietes baties is the owner tax. Article 1380 of the General Tax Code states: “La taxe foncière est établie annuellement sur les propriétés bâties sises en France à l’exception de celles qui en sont expressément exonérées par les dispositions du présent code.” In plain terms, every built property in France is caught each year unless a specific exemption applies. New builds, properties owned by certain public bodies and a few rural or energy-renovation cases can be exempt, but an ordinary second home owned by a British individual is not. The bill is issued in the name of the person who owns the property on 1 January of the tax year, even if you sell during the year. Notaries adjust this between buyer and seller in the completion accounts, but against the tax office the 1 January owner remains liable. The base is the valeur locative cadastrale (the notional rental value recorded by the land registry, reduced by a 50% allowance for built property), multiplied by the rates voted by the commune, the intercommunal body and, in the past, the department. That is why two identical houses a few miles apart can produce very different bills: local rates dominate the result.
British buyers are often surprised by how little room there is to argue the rate itself. Councils vote their rates each spring within national ceilings, and the rate is lawful even if it rises sharply, provided the vote and the publication formalities were regular. Your realistic lines of challenge on taxe fonciere are therefore factual: wrong property description, wrong floor area, a garage or outbuilding that no longer exists, a new build exemption that was never applied, a demolition or conversion the land registry never recorded, or a personal exemption you qualify for but were never granted. Keep your purchase deed (acte authentique), the seller’s diagnostics, planning permissions and any demolition certificates, because the tax office reasons from its cadastral file, not from what you see on site. If the cadastral entry is wrong, you must get both the assessment corrected and the cadastral record updated, otherwise the same error returns every year.
The second annual bill is the taxe d’habitation sur les residences secondaires. Since the abolition of this tax on main homes, completed for most households by 2023, only second homes and certain furnished premises remain liable. Article 1407 of the General Tax Code states: “La taxe d’habitation sur les résidences secondaires est due pour tous les locaux meublés conformément à leur destination d’habitation autre qu’à titre principal, y compris lorsqu’ils sont imposables à la cotisation foncière des entreprises.” The exclusions that follow cover hostels for people in difficulty, pupil and student housing and tourist accommodation defined by the Tourism Code, not an ordinary British-owned holiday flat. The liable person is the occupier, not necessarily the owner. Article 1408 of the General Tax Code states: “La taxe est établie au nom des personnes qui ont, à quelque titre que ce soit, la disposition ou la jouissance des locaux imposables.” If you keep the keys and can stay there whenever you wish, you have disposition even if you spend only three weeks a year in France. If you let the property year-round on an unfurnished long lease, the tenant becomes the occupier for this tax, though in practice most British second homes are kept furnished for the owner’s use and remain taxable on the owner. A company structure does not remove the charge: companies holding dwellings under time-share allocation are expressly made liable for the tax on the units allocated to their members.
The painful part for second-home owners is the local surcharge called majoration de la taxe d’habitation sur les residences secondaires. In designated tight-housing zones, the municipal council can vote an uplift. Article 1407 ter of the General Tax Code states that the council may act “majorer d’un pourcentage compris entre 5 % et 60 % la part lui revenant de la cotisation de taxe d’habitation sur les résidences secondaires due au titre des logements meublés.” Paris, much of the Paris region, the Basque coast, the French Riviera, Bordeaux, Lyon, Annecy and many Alpine and coastal resorts have voted the upper end of that range, so a British-owned flat in Paris or Biarritz can carry a 60% uplift on the communal share. The statute then provides three cases for relief from that uplift on claim, within the time limit and forms of the Tax Procedures Book: people forced for work to live away from their main home and keeping a flat near work, people who previously lived in the flat as their main home before moving durably into a care institution covered by Article 1414 B, and people who for a reason beyond their will cannot turn the dwelling into their main home. The wording matters because the tax office applies it narrowly: owning a second home because you love France, or because you work in London and holiday in France, is not a cause beyond your will. A compulsory professional transfer, a building declared unfit for year-round living, or a long hospital stay documented by evidence, can be. Each relief must be claimed; none is automatic, and the cost of relief granted is borne by the commune, which explains why town halls check claims carefully.
Practical consequences follow directly. First, tell the tax office how each property is occupied through the online gerer mes biens immobiliers declaration on impots.gouv.fr: main home, second home, vacant, let furnished, let unfurnished, occupied free of charge. Fines apply for missing or wrong occupancy declarations, and the declaration feeds both taxe d’habitation and the annual rent-control and vacancy taxes. Second, if you divide your time between Britain and France, keep evidence of where your main home really is: council tax bills, UK electoral roll, GP registration, children’s schooling, energy consumption in France. The tax office cross-checks electricity use, and a flat declared as a main home but consuming almost no power invites reclassification as a second home with back tax. Third, if you buy through a societe civile immobiliere (SCI, the French non-trading property company often used by British families), remember that the SCI does not shield the dwelling from these taxes; it changes who is assessed and how income is taxed, not whether local property taxes are due. The purchase process itself, including notaire fees and registration duty, belongs to conveyancing and is outside this guide; here you own the person and the annual bill.
Official guidance helps you map the bill before you dispute it. The service-public.fr pages on taxe fonciere and taxe d’habitation sur les residences secondaires set out who is liable, the 1 January rule and the surcharge zones in plain French, while the impots.gouv.fr notices attached to each avis d’imposition (assessment notice) show the cadastral base, the rates applied and the reference to the deliberation that voted the surcharge. On the British side, the gov.uk guidance on living in France and on tax if you leave the United Kingdom confirms that owning property abroad does not by itself keep you UK-resident, and that you must still report worldwide circumstances to HM Revenue and Customs. None of those pages decides your French liability; only the statute and your assessment do. But they tell you which box on the assessment to read first, which is where most successful challenges start.
B. IFI Wealth Tax for Britons After Brexit: the 1.3 Million Euro Threshold, Non-Residents and Valuation
The third tax catches fewer people but at higher stakes. The impot sur la fortune immobiliere (IFI) replaced the former wealth tax on all assets in 2018 and taxes only net property wealth. Article 964 of the General Tax Code states: “Il est institué un impôt annuel sur les actifs immobiliers désigné sous le nom d’impôt sur la fortune immobilière.” Liability starts only “lorsque la valeur de leurs actifs mentionnés à l’article 965 est supérieure à 1 300 000 €”. The threshold is assessed on the household (foyer fiscal) on 1 January each year: married couples are taxed jointly, as are civil partners under a pacte civil de solidarite (PACS, the French registered partnership) and couples in established cohabitation, unless one of the narrow exceptions in Article 6 applies. Adult children living separately form their own household; minor children form part of yours.
Brexit did not create a special IFI rule for Britons, and that is precisely the point to grasp. The statute divides the world into French tax residents and non-residents. French residents are taxed on worldwide qualifying property; newcomers who were not French-resident during the previous five calendar years benefit for five years from an inbound relief taxing only French property. Article 964 then deals with non-residents in these terms: “Les personnes physiques n’ayant pas leur domicile fiscal en France, à raison des biens et droits immobiliers mentionnés au 1° de l’article 965 situés en France” — the article then extends the charge to shares or units representing such French property, in proportion to the underlying French assets A British tax resident living in London and owning a house in Provence above the threshold is therefore within IFI on the French property and on shares representing French property, but not on a flat in Manchester. A British tax resident living in France is within IFI on French and British property together, subject to the France-United Kingdom double tax arrangements and to ordinary valuation and debt rules. Domicile for tax (domicile fiscal) follows French domestic criteria and the treaty tie-breaker where both States claim you; it is not decided by your passport, your visa or your Withdrawal Agreement residence card.
What counts is defined by Article 965: direct holdings in buildings and land, rights in rem such as usufruct, and shares or units in companies and bodies to the extent they represent French or worldwide taxable property, with listed exemptions for business property, woodland under management commitments and certain rental businesses. Debts are deductible only under tight conditions introduced to curb artificial leveraging, notably loans taken out to buy the taxable asset or to fund qualifying works, with annual amortisation tracked year by year. Bare ownership, usufruct splits after a gift, and outstanding balances on an English mortgage secured on the French house all raise valuation questions that must be documented with the loan offer, the annual statement and the exchange rate used on 1 January. Keep valuations consistent across IFI, gift and succession files: a house declared at 900,000 euros for IFI and at 1,400,000 euros for a later sale invites a reassessment.
Valuation follows death-duty rules with one major relief for the main home. Article 973 of the General Tax Code provides: “un abattement de 30 % est effectué sur la valeur vénale réelle de l’immeuble lorsque celui-ci est occupé à titre de résidence principale par son propriétaire.” Only one property per household can benefit, and only the dwelling actually occupied as the main home on 1 January. A British-owned second home never qualifies, even if it is your most valuable asset. Listed securities are taken at the last known price or the average of the last thirty prices before 1 January. For shares in property companies, the statute excludes certain related-party debts from the valuation and caps the taxable value by reference to the underlying property, which is why SCI balance sheets must be restated for IFI rather than copied from the company accounts. If your net taxable property hovers around 1.3 million euros, commission an independent valuation every two to three years and keep comparable sales: the tax office values pragmatically from notarial databases, and a reasoned valuer report settles more files than lengthy legal argument.
Two boundary points deserve emphasis because British owners often misunderstand them. First, trusts. An English discretionary trust holding French property does not make the property disappear for IFI; French law imposes specific declaratory duties on trustees and treats the settlor and deemed settlors as liable in defined cases, with heavy fines for non-declaration. If a trustee tells you that a trust is invisible in France, seek French advice before the next IFI deadline. Second, rental activity. Letting a French property furnished or unfurnished does not exempt it from IFI, though genuine professional letting businesses can qualify for business-property relief under strict conditions of activity, registration and personal involvement. A holiday home let a few weeks a year on a platform is not a professional letting business. Report the asset, value it properly, deduct only qualifying debt, and challenge the valuation if needed rather than omitting the asset.
II. Checking Your Bill and Challenging It: the Reclamation, the Court and the Costs
A. Reading Your Avis d’Imposition, Fixing Cadastral Errors and Filing the Reclamation Within the Deadline
Every successful challenge starts with the avis d’imposition (the assessment notice) and the underlying tax roll (role). For taxe fonciere the notice shows the cadastral rental value, the allowance, the rates for each collecting body, any exemption or relief, and the total. For taxe d’habitation sur les residences secondaires it shows the occupier’s name, the dwelling’s occupancy code, the base, the communal and intercommunal rates, and any voted surcharge with its percentage. For IFI it shows the declared base, the household composition and the scale. Download the detailed calculation (decompte) from your impots.gouv.fr personal account and compare it line by line with your deed, your floor plans and your occupancy declaration. The most common winnable errors are prosaic: a surface area carried over from before renovation, a swimming pool recorded twice, a dependance that was demolished, a property recorded as vacant when let, or a second home coded as occupied by a tenant who left two years ago. Photographs with dates, builder invoices, demolition receipts, leases, meter readings and the land registry extract (releve de propriete) carry more weight than general complaints about high rates.
French tax disputes are first administrative, then judicial. You must file a prior complaint called a reclamation contentieuse before you can go to court for money. Article L190 of the Tax Procedures Book states: “Les réclamations relatives aux impôts, contributions, droits, taxes, redevances, soultes et pénalités de toute nature, établis ou recouvrés par les agents de l’administration, relèvent de la juridiction contentieuse lorsqu’elles tendent à obtenir soit la réparation d’erreurs commises dans l’assiette ou le calcul des impositions, soit le bénéfice d’un droit résultant d’une disposition législative ou réglementaire.” In other words, if you seek discharge or reduction for a wrong base, a wrong calculation or a statutory right such as an exemption or a surcharge relief, you are in adversarial tax litigation and the prior complaint is the gateway. File online from your impots.gouv.fr messaging service (reclamer function) or by signed letter to the tax centre shown on the notice (centre des finances publiques, service des impots des particuliers). Identify the tax, the year, the reference of the notice, the amount disputed, the legal basis and the evidence, and ask expressly for discharge or reduction (decharge ou reduction) plus statutory late-payment interest on repayment. Keep proof of filing and the acknowledgment; from Britain, use the online route so the timestamp is indisputable.
Time limits are strict and run against owners abroad exactly as against owners in France. Local taxes must generally be claimed by 31 December of the year following the year the roll was issued, with longer extensions only where the statute expressly provides them, for example after a reassessment or a court decision revealing a higher-law incompatibility. The surcharge relief under Article 1407 ter must be sought “sur reclamation presentee dans le delai prevu” in the Tax Procedures Book and in the prescribed forms, which in practice means within the same complaint window and with the supporting evidence for work-related separation, care-home transfer or outside cause. Do not wait for the enforcement stage: the avis de mise en recouvrement and reminders do not reopen the assessment deadline. Paying first does not weaken your claim; on the contrary, paying avoids the 10% surcharge for late payment and penalty interest while the complaint is examined, and repayment with interest follows if you win. If cash flow is tight, apply separately for a stay of payment (sursis de paiement) with guarantees where required, but never treat a stay application as a substitute for the complaint itself.
The tax office has, in principle, six months to answer a contentious complaint on local taxes and IFI, after which silence counts as an implied refusal that you may take to court. Express refusals arrive as reasoned decisions citing the articles applied. Read the refusal closely: it tells you which court the administration thinks is competent, restates the facts it accepts, and often discloses the cadastral or valuation evidence it relied on. If the refusal corrects part of the error but not all, you may accept the partial relief and litigate only the remainder; the court will decide only what remains in dispute. If the office asks for more documents, reply within the time it sets and keep copies, because the court will later ask what you disclosed during the prior stage. From London, Manchester or Edinburgh, appoint a French correspondent or representative with an explicit mandate to receive mail, because notices sent to a French address you rarely visit are still deemed notified, and court deadlines will not wait for your next trip.
B. Taking the Refusal to the Right Judge, Claiming Interest and Organising Your Proof From Britain
The competent court depends on the tax. Article L199 of the Tax Procedures Book draws the line in two sentences. First: “En matière d’impôts directs et de taxes sur le chiffre d’affaires ou de taxes assimilées, les décisions rendues par l’administration sur les réclamations contentieuses et qui ne donnent pas entière satisfaction aux intéressés peuvent être portées devant le tribunal administratif.” Taxe fonciere and taxe d’habitation are direct local taxes, so the tribunal administratif (administrative court) of the place of assessment hears them. Second: “En matière de droits d’enregistrement, d’impôt sur la fortune immobilière, de taxe de publicité foncière, de droits de timbre, de contributions indirectes et de taxes assimilées à ces droits, taxes ou contributions, le tribunal compétent est le tribunal judiciaire.” IFI therefore goes to the tribunal judiciaire (ordinary civil court), not the administrative court. Filing in the wrong court wastes months and can forfeit the deadline, so check the refusal letter, the impots.gouv.fr help pages and, if in doubt, file protectively in the court indicated while asking the registry to transfer if needed. For owners in Paris and the Paris region, the competent administrative court is normally the tribunal administratif de Paris for Paris assessments, or Versailles, Melun, Bobigny or Cergy-Pontoise for the inner and outer suburbs according to the situs of the property; IFI cases go to the judicial court of the tax office that issued the notice, with representation by counsel required in most civil proceedings.
Once before the court, the deadline is short. Article R421-1 of the Administrative Justice Code states: “La juridiction ne peut être saisie que par voie de recours formé contre une décision, et ce, dans les deux mois à partir de la notification ou de la publication de la décision attaquée.” The same two-month logic governs most tax appeals after an express refusal, and an implied refusal after six months of silence opens its own window that you should not let drift. The application must identify the decision challenged, state the facts, set out the legal pleas (moyens) with the exact articles relied on, quantify the relief sought and attach the assessment, the complaint, the refusal and the evidence bundle. Before the administrative court you may in many tax cases represent yourself, but from Britain that is rarely wise: procedure is written, French-language, and conducted through the Telerecours platform, with strict rules on copies, service and reply deadlines. Before the judicial court for IFI, representation by an avocat (advocate, the regulated legal profession entitled to plead) is normally required. Budget for an expert valuation where IFI or a cadastral base is at stake; courts give decisive weight to reasoned comparable-based reports over bare assertions of overvaluation.
Remedies go beyond the principal. If the court discharges or reduces the tax, it orders repayment of the undue amount with statutory moratory interest from the date of payment, and the administration must re-liquidate the assessment. If only the surcharge is at stake, the court can discharge the uplift while leaving the base tax intact, which is why your claim should separate the base, the rates and the surcharge in distinct heads. Costs (frais irrepetibles) may be awarded against the losing administration where your claim was well-founded and documented, though they rarely cover the full legal bill. Conversely, a wholly unfounded claim can attract a costs order against you. Interest for late payment charged during the dispute falls with the principal where you win; where you lose, it stands, which is another reason to pay the disputed bill early or secure a formal stay rather than simply ignoring reminders. Enforcement by seizure (saisie) or by aعه third-party notice (avis à tiers détenteur) while the complaint or appeal is pending can itself be challenged where a stay was granted or where formalities were breached, but the assessment dispute and the enforcement dispute run on separate tracks with separate judges.
Organisation from Britain decides more cases than fine legal theory. Centralise each property in a yearly file: deed, floor area, cadastral extract, occupancy declaration, energy bills, lease or absence of lease, council deliberation on the surcharge if published, assessment notice, complaint with acknowledgment, refusal, court application with stamps. Translate only what the court needs: the court works in French, so your English exhibits should carry short French captions or certified translations for decisive pages, while statutes are cited in French with your English explanation alongside. Where the dispute turns on occupation — second home versus main home, vacant versus let, professional versus private use — contemporaneous evidence wins: dated meter readings, insurance schedules distinguishing second-home cover, travel records, and correspondence showing who held the keys. Where it turns on value — cadastral base or IFI — method wins: comparable sales within the same micro-market and year, adjustments for condition and outlook, and a valuer who explains the method rather than merely stating a figure. Courts in high-pressure zones see surcharge cases every month; a file that isolates the exact legal question, quantifies each head of claim and proves each fact in dated order stands out immediately.
Finally, keep the treaty and residence layer in its proper place. The France-United Kingdom double tax treaty allocates taxing rights over income and over estates; it does not govern taxe fonciere or taxe d’habitation, which remain purely domestic local taxes on French situs property, and it touches IFI-type wealth taxes only through non-discrimination and information-exchange mechanics rather than a general exemption. Do not plead the treaty against a local property tax bill; plead the domestic articles above, the cadastral facts and the procedural deadlines. Use the treaty where it belongs: to settle whether you are French-resident for IFI scope, to claim a foreign tax credit on British rental income that funds the French bills, or to coordinate succession planning for the house itself. That discipline — domestic property tax law for the annual bills, treaty law for residence and income allocation — is what separates a focused, winnable file from a sprawling letter that the tax office and the court both set aside.
Conclusion
Owning a French house from Britain after Brexit means living with three French taxes assessed under French rules: an owner-based taxe fonciere on every built property, a second-home taxe d’habitation with a voted uplift of 5% to 60% in tight zones, and an IFI wealth tax once net property exceeds 1,300,000 euros on 1 January. None depends on your passport; all depend on the cadastral record, the occupancy declared, the value proved and the deadline met. Check each avis d’imposition against the deed and the facts, correct the occupancy declaration, file a reasoned reclamation contentieuse within the statutory window, then take an unsatisfactory answer to the tribunal administratif for the two local taxes or to the tribunal judiciaire for IFI within two months, with interest and costs claimed alongside the principal. Handled that way, from an organised yearly file managed online from the United Kingdom, most errors — wrong area, wrong occupier, wrong surcharge, wrong valuation — can be corrected without drama. Left unopened until enforcement, the same bills become surcharges, seizures and missed deadlines that no court can reopen.
