You are British, you own a house or flat in France, and the 2026 taxe fonciere bill has just landed in your online tax account or your letterbox. Since Brexit, that bill can feel harder to read: you pay in euros from a British bank account, the explanatory notes are in French, and you are no longer sure whether the old European rules still protect you. This guide is written for you. It explains, entirely in English, how the 2026 French property tax on built properties works, who must pay it after Brexit, how the amount is calculated, what relief a British owner can still claim, and how to challenge an incorrect assessment before the deadline expires.
The taxe fonciere sur les proprietes baties, literally the land tax on built properties, is the annual local property tax paid by the owner of any house, flat, garage or commercial building in France. It is different from the taxe d’habitation on second homes, which is the occupancy tax that now survives only on second homes and furnished premises that are not your main residence. Many British owners receive both bills in the autumn and confuse them. This article deals only with the taxe fonciere for 2026, including the payment deadlines of 15 and 20 October 2026 announced by the tax administration, and the complaint deadline of 31 December 2027. Where a point also matters for the taxe d’habitation on your second home, we signpost our companion analysis so you can read both without mixing the two regimes.
Brexit did not change the taxe fonciere itself. British owners pay under exactly the same code articles as French owners. What Brexit changed is your daily context: you may now be non-resident for French income tax while remaining liable to French local taxes on your French house, you may struggle to use the online complaint portal without a French mobile number, and you may miss paper notices sent to a French address you visit only in summer. The law, however, shows no leniency for a missed deadline because you were in the United Kingdom when the bill arrived. That is why the second half of this guide is deliberately practical: what to check line by line on the 2026 notice, which supporting documents to gather now, and how to file a formal complaint, called a reclamation, that preserves your right to go to the administrative court if the administration says no.
I. How your 2026 taxe fonciere bill is worked out and who must pay it after Brexit
Before you can decide whether your 2026 bill is wrong, you need to understand what the administration actually taxed. The taxe fonciere is not a wealth tax, not a capital gains tax and not a charge for local services consumed. It is a tax on ownership itself, assessed once a year by reference to the situation on 1 January, and calculated from a notional rental value that often has little to do with the rent your house could achieve on the market in 2026. British readers who think in terms of council tax bands should set that reflex aside: there are no bands, there is a cadastral value per property, multiplied by rates voted each year by the local councils.
A. How the cadastral rental value and the 50 percent allowance produce your 2026 bill
The starting point is article 1380 of the French General Tax Code, the Code general des impots, which states that:
“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.” (article 1380 of the General Tax Code)
In plain English: the tax is assessed every year on built properties situated in France, except those expressly exempted by the Code. Your cottage in the Dordogne, your flat in Paris and your villa on the Riviera are all within the scope. The fact that you are British, resident in London, Manchester or Edinburgh, changes nothing at this stage. If the building stands in France, it is taxable in France.
The taxable base is then defined by article 1388 of the General Tax Code, which provides that:
“La taxe foncière sur les propriétés bâties est établie d’après la valeur locative cadastrale de ces propriétés déterminée conformément aux principes définis par les articles 1494 à 1508 et 1516 à 1518 B et sous déduction de 50 % de son montant en considération des frais de gestion, d’assurances, d’amortissement, d’entretien et de réparation.” (article 1388 of the General Tax Code)
Three ideas in that single sentence explain most of the surprises on British owners’ bills, so each deserves a clear explanation.
First, the valeur locative cadastrale, the cadastral rental value, is the notional annual rent the administration attributes to your property. For houses built before 1970, and for many older village houses owned by British buyers, that value still derives from the general revision of 1970, updated each year by national coefficients. For newer buildings it derives from the declared surface, comfort elements and comparison with reference premises, called locaux de reference, in the same commune. In both cases the figure can look archaic: a stone farmhouse modernised to a high standard may carry a modest cadastral value because its classification was never revised, while a small new-build with air conditioning and a swimming pool may carry a surprisingly high one. The Conseil d’Etat, the highest administrative court, polices this exercise closely. In decision no. 421173 of 13 February 2020, it recalled the wording of article 1498 then in force:
“La valeur locative de tous les biens autres que les locaux visés au I de l’article 1496 et que les établissements industriels visés à l’article 1499 est déterminée au moyen de l’une des méthodes indiquées ci-après” (decision no. 421173 of 13 February 2020)
and held that, where the value is set by comparison, the comparison terms used:
“doivent être constitués par des immeubles précisément identifiés, situés par priorité sur le territoire de la commune, et dont la valeur locative a été déterminée au moyen de l’une des deux méthodes qu’elles prévoient.” (decision no. 421173 of 13 February 2020)
For you as a British owner, the practical lesson is concrete. If your 2026 bill has jumped because the cadastral value looks inflated, your complaint must attack the comparison: ask the tax office, the service des impots des particuliers, to disclose the reference premises used for your house, check whether they are genuinely comparable and situated in your commune, and point to identified comparable houses with lower values. A general statement that the rent is too high never succeeds. Identified local comparables sometimes do.
The current version of article 1498 of the General Tax Code now organises the same logic for residential premises through classification into sub-groups and tariff categories, but the principle is unchanged: the administration must reason from observable local rental evidence, not from an abstract market view. Keep photographs, the surface breakdown on your deed, the diagnostic reports and any evidence that part of the building is derelict or uninhabitable. Those documents become decisive if you challenge the base.
Second, the 50 percent deduction, called the abattement forfaitaire de 50 %, is automatic. The administration halves the cadastral value to allow for management, insurance, depreciation, maintenance and repair costs. You do not need to claim it and you cannot claim your actual expenses instead. British owners who have spent large sums on a new roof or a septic tank sometimes argue that their real costs exceed 50 percent. That argument is legally irrelevant to the taxe fonciere. Real renovation costs matter for income tax and capital gains, not here.
Third, the halved base is multiplied by the taux d’imposition, the tax rates voted by the commune, the intercommunal body and, for some additional levies, other public bodies. Added to that product are the flat management fees, the frais de gestion, and, very often, the taxe d’enlevement des ordures menageres, the household waste collection tax, known as TEOM, plus the levy for the management of aquatic environments and flood prevention, known as GEMAPI. That is why two identical houses a few streets apart, on either side of a municipal boundary, can bear very different bills. When British buyers compare notes on expatriate forums, they often compare headline totals without realising the rates differ by commune. Always compare the base and each rate line by line, not only the final sum.
For 2026, the administration has confirmed the timetable British owners must diarise. Notices went online from 27 August 2026 for taxpayers who do not pay monthly, and from 19 September 2026 for monthly payers, with paper notices posted between 24 August and 21 September 2026, or between 21 September and 9 October 2026 for monthly payers, as explained on the official impots.gouv.fr page on when you receive your notice. The payment deadline is 15 October 2026 if you pay by cheque, cash within limits or other non-online means, and 20 October 2026 at midnight if you pay online through impots.gouv.fr or the smartphone application. The Service Public news item updated on 8 September 2026 confirms the online deadline of 20 October 2026 at midnight and the availability of notices in your online Documents tab. If your notice arrives late, the payment deadline moves accordingly, but never assume an extension: read the date printed on your own notice and pay on time even if you intend to complain, because a complaint does not suspend collection unless you expressly request and obtain a stay.
British-specific friction deserves a paragraph. After Brexit, many British owners lost easy access to a French bank account or changed banks, and direct debits fail. Others never activated online access to impots.gouv.fr because the activation letter went to the French house while they were in Britain. Neither excuses late payment penalties, the majoration de 10 %, or late interest. If your online account is blocked, pay by another accepted means before the deadline and sort out access afterwards. Keep proof of every payment from the United Kingdom, including transfer confirmations showing value dates, in case a payment made on time is credited late.
B. Who is liable on 1 January and what happens on sale, usufruct or letting after Brexit
The second threshold question is who the debtor is. Article 1400 of the General Tax Code answers it in terms that surprise many British sellers and buyers:
“Sous réserve des dispositions des articles 1403 et 1404 , toute propriété, bâtie ou non bâtie, doit être imposée au nom du propriétaire actuel.” (Article 1400 of the General Tax Code)
And article 1415 of the General Tax Code fixes the relevant date:
“La taxe foncière sur les propriétés bâties, la taxe foncière sur les propriétés non bâties et la taxe d’habitation sur les résidences secondaires sont établies pour l’année entière d’après les faits existants au 1er janvier de l’année de l’imposition.” (article 1415 of the General Tax Code)
In other words, the person who owns the property on 1 January 2026 owes the whole 2026 bill, even if they sell on 2 January, even if they move back to Britain in February, and even if the house sits empty for the rest of the year. There is no pro rata by month of ownership as far as the Treasury is concerned. British conveyancers sometimes tell sellers that the buyer will reimburse a share. That is true between the parties, under a private apportionment clause, called a prorata, in the sale deed, the acte de vente, usually adjusted by the notaire, the French conveyancing notary. But it does not bind the tax office. If the notaire did not collect the buyer’s share at completion, the seller remains liable to the State for the full amount and must recover the share from the buyer under civil law.
If you sold your French house in 2025 and still receive a 2026 bill, act quickly rather than ignoring it. The most common cause is a delay in registering the transfer in the cadastral records, especially when the sale completed in December. Write to the tax office of the property with a copy of the deed showing the date of transfer and the cadastral references, and ask for the record to be corrected. If you bought in late 2025, the mirror applies: check that the bill is in your name, because an assessment still addressed to the seller does not make you exempt, and unpaid tax can lead to enforcement against the property.
Usufruit, the civil-law right to use a property and take its income for life or for a fixed term, which British families encounter when a parent gifts the bare ownership to children while keeping the use, follows its own rule under the same article 1400: where a building is subject to usufruct, the tax is assessed in the name of the usufruitier, the holder of the right, not the nu-proprietaire, the bare owner. British parents who made a donation-partage, a gift partition before a notary, and kept the usufruct sometimes assume the children now pay. They do not. The parent in usufruct pays the taxe fonciere, while the children will pay it only when the usufruct ends. Our companion analysis on gifts of a French house to children explains the wider gift and inheritance picture; for the annual bill, remember this single line: usufruct pays.
Letting the house changes nothing as against the State either. A British owner who lets a Dordogne house on a long-term lease or through seasonal furnished lettings remains the taxpayer. Any clause making the tenant reimburse the tax is a private matter and, for residential leases under the French Housing Act, the recoverable element is limited and contested. Do not deduct the taxe fonciere from the rent without legal advice. Similarly, vacancy does not suspend the tax. An empty second home still bears the full taxe fonciere, and in some communes it also bears the surcharged taxe d’habitation on second homes and the vacancy tax, which are separate assessments with their own challenge routes described in our guide for British owners facing a French second-home tax bill.
New buildings and extensions follow article 1383 of the General Tax Code, which states:
“Les constructions nouvelles, reconstructions et additions de construction à usage d’habitation sont exonérées de la taxe foncière sur les propriétés bâties durant les deux années qui suivent celle de leur achèvement.” (article 1383 of the General Tax Code)
New residential buildings, rebuilds and extensions for housing are therefore exempt for the two years after the year of completion. British owners who built a pool house, converted a barn or added an extension sometimes discover a supplementary assessment, called a cotisation supplementaire, a year later, when the tax office catches up with the change. Conversely, some continue to enjoy the exemption because the commune limited it by vote to 40 to 90 percent of the base for its share, which the same article allows. If your new-build exemption looks wrong, check the completion declaration, the declaration d’achevement, you or your builder filed, and the deliberation of your commune. Late declaration can cost you the exemption, which is why builders’ paperwork should be kept with the deeds, not left in a drawer in Britain.
Finally, ownership through a French property company, the societe civile immobiliere or SCI that many British families use to hold a French house, does not shift the annual bill away from France. The SCI as owner is the taxpayer, and the managers must pay from company funds and reflect the charge in the accounts and the annual 2072 return. If the SCI lets the house, the rent is company income; if it lends it free to the family, other tax consequences arise, but the taxe fonciere remains due in full. Our detailed guide on the British family SCI for a French house covers the holding, tax and succession logic; the message for this article is narrower: do not assume that interposing a company defers or divides the 2026 bill.
II. How to pay less or challenge your 2026 taxe fonciere bill after Brexit
Knowing how the bill is built and who owes it lets you move to the question British owners actually ask in September and October: can I pay less, and if the bill is wrong, how do I fight it from across the Channel before it is too late. The honest answer has two halves. Genuine exemptions and reliefs exist but are narrow, residence-based and income-tested, so most British second-home owners will not qualify. Challenges to errors, by contrast, succeed regularly when they are precise, documented and filed on time. This part maps both routes in the order you should work through them: first check whether you qualify for an exemption, then, if not, check whether the bill itself is wrong and complain in the form the law requires.
A. Which exemptions and reliefs a British owner can still claim for the 2026 bill
Start with a Brexit clarification that causes constant confusion. British citizens are now third-country nationals for European Union law purposes, but the taxe fonciere exemptions do not depend on nationality. They depend on age, disability benefits, income, occupation of the dwelling as your main home, and the nature of the building. A British passport neither grants nor removes them. What matters is whether you satisfy the French statutory conditions on 1 January 2026, with French-taxable income evidence where thresholds apply.
The two most invoked age and benefit exemptions are codified at articles 1390 and 1391. Article 1390 of the General Tax Code provides that:
“Les titulaires de l’allocation de solidarité aux personnes âgées mentionnée à l’article L. 815-1 du code de la sécurité sociale ou de l’allocation supplémentaire d’invalidité mentionnée à l’article L. 815-24 du même code sont exonérés de la taxe foncière sur les propriétés bâties dont ils sont passibles à raison de leur habitation principale.” (Article 1390 of the General Tax Code)
Holders of the French old-age solidarity allowance or the supplementary disability allowance are therefore exempt on their main home. A British pensioner receiving only the United Kingdom State Pension does not hold those French allowances and cannot invoke this article by equivalence. Only a British resident affiliated to the French social security system who actually receives one of the named French benefits qualifies.
Article 1391 of the General Tax Code helps a slightly wider group:
“Les redevables âgés de plus de soixante-quinze ans au 1er janvier de l’année de l’imposition sont exonérés de la taxe foncière sur les propriétés bâties pour l’immeuble habité par eux, lorsque le montant des revenus de l’année précédente n’excède pas la limite prévue à l’article 1417” (Article 1391 of the General Tax Code)
Taxpayers over seventy-five on 1 January are exempt on the dwelling they live in, provided the previous year’s income does not exceed the ceiling set by reference to article 1417. Three conditions must coincide: age over seventy-five, occupation of the property as your home, and modest income under the statutory ceiling. A seventy-eight-year-old British owner who lives in France year-round in the taxed house and whose worldwide income declared in France stays below the ceiling can qualify exactly like a French neighbour. A seventy-eight-year-old who keeps the French house as a holiday home while living in Kent cannot, because the taxed house is not the dwelling lived in as the main home. Second homes are structurally excluded from these two reliefs.
Younger British residents sometimes ask about the income-capped reliefs for those aged sixty-five to seventy-five, the disabled, or households of modest means. Those mechanisms exist but each turns on the revenu fiscal de reference, the French reference tax income, and on continuous occupation conditions that are verified from your French income tax return. If you arrived in France during 2025 and filed your first French return in 2026, check that the income figure the local tax office holds for you is complete and correct, because a missing or overstated reference income is a frequent cause of a refused relief that a documented complaint can repair. If you remain tax-resident in the United Kingdom and file no French income return, the administration has no reference income on which to grant an income-tested relief, and your request will almost certainly fail. In that configuration, do not waste the complaint deadline on a relief you cannot evidence; concentrate on checking the base, the rates and the identity of the taxpayer.
Two further reliefs deserve a short, honest mention. The two-year exemption for new residential buildings under article 1383, quoted above, helps British owners who completed a house or a genuine extension in 2024 or 2025 and correctly declared completion. Agricultural, forestry and certain rural buildings benefit from permanent exemptions and abatements of their own, which matter if your French smallholding includes barns and outbuildings classified as rural dependencies rather than housing. The classification on the cadastral matrix, not the estate agent’s description, decides. If a barn converted into a gite now appears as housing, it is taxed as housing.
What about paying in instalments or obtaining a grace period because sterling transfers are difficult. Monthly payment, the prelevement mensuel, and payment at the due date by direct debit, the prelevement a l’echeance, are open to British owners with a SEPA-compatible account, including many United Kingdom accounts, but mandates should be set up well before October. If you face genuine hardship, a request for a payment delay, a demande de delai de paiement, or for a discretionary rebate of penalties, a remise gracieuse des majorations, can be addressed to the local finance office with bank statements, proof of the sterling transfer costs and a realistic payment plan. Those are discretionary favours, not rights, and they never extend the complaint deadline. Always file the complaint and ask for payment facilities in parallel, in separate letters, so that kindness cannot swallow rights.
A final warning for British owners who also rent out the house. Short-term furnished letting profits, declarable in France under the micro-BIC or actual profit regimes, can push your reference income above the relief ceilings and can affect the classification of outbuildings. Run the letting and relief questions together with your accountant before you claim. A relief granted on an incomplete income picture can be withdrawn with penalties, while a well-documented rental file strengthens a challenge to an overstated cadastral value because it evidences the real rental level.
B. How to challenge an incorrect 2026 bill and what deadline applies from Britain
If no exemption fits, or alongside an exemption claim, examine the bill for the four errors that account for most successful complaints: wrong taxpayer after a sale or death, wrong base after unrecorded demolition, extension or subdivision, wrong rate or additional levy that your commune never voted, and double counting of a dependency. Then complain in the only form that counts. French tax litigation is built on a mandatory prior complaint to the administration before any judge can be seised. Article R*190-1 of the Tax Procedure Book, the Livre des procedures fiscales, states the rule without ambiguity:
“Le contribuable qui désire contester tout ou partie d’un impôt qui le concerne doit d’abord adresser une réclamation au service territorial, selon le cas, de la direction générale des finances publiques ou de la direction générale des douanes et droits indirects dont dépend le lieu de l’imposition.” (Article R*190-1 of the Tax Procedure Book)
A letter to your Member of Parliament, a post on a forum, a telephone call to the national helpline or an email to the wrong office does not satisfy that requirement. The complaint must reach the territorial department that manages the place of taxation, in practice the service des impots des particuliers of the property, or be filed through the secure messaging of your online account on impots.gouv.fr, which routes it correctly and generates a receipt. From Britain, the online route is strongly preferable because it avoids postal delays and creates timestamped proof.
The deadline is strict and Brexit-blind. Article R*196-2 of the Tax Procedure Book provides:
“Pour être recevables, les réclamations relatives aux impôts directs locaux et aux taxes annexes doivent être présentées à l’administration des impôts au plus tard le 31 décembre de l’année suivant celle, selon le cas : a) De la mise en recouvrement du rôle, de la notification d’un avis de mise en recouvrement ou de l’émission d’un titre de perception” (Article R*196-2 of the Tax Procedure Book)
For the 2026 taxe fonciere, that means 31 December 2027. The Service Public article on how to challenge your assessment, updated on 8 September 2026, states the same practical conclusion in plain terms: if you spot an error, you have until 31 December 2027 to complain. Do not confuse that outer limit with a reason to wait. Evidence fades, builders disappear, estate agents delete listings, and a complaint filed in October 2026 while the 2026 roles are fresh carries more weight than one filed fifteen months later. If you pay monthly, the same outer date applies, counted from the collection of the role, not from your last monthly debit.
Your complaint letter, in French with an English translation kept for your file, should contain six elements: your name, address in France and in Britain, and French tax number, the numero fiscal; the cadastral references and address of the property; the tax year and the assessment number, the numero d’avis; a clear statement of what you seek, total discharge, called degrevement, or reduction, called reduction; the legal and factual grounds in numbered paragraphs; and a numbered bundle of supporting documents. Typical bundles include the sale deed or probate documents proving ownership on 1 January, the completion or demolition declarations, dated photographs, the diagnostic surface measurements, the leases or attestations showing vacancy or ruin, the commune’s rate deliberations if you dispute a levy, and, for cadastral value disputes, the identified local comparables with their own cadastral extracts where obtainable. Keep every page, because the judge will later see only what the administration saw, plus what you add at the court stage within the rules.
After you file, the administration has six months to answer, and silence for six months counts as an implied rejection that you can take to court. If the administration rejects expressly, you have two months from receipt of the rejection to seise the administrative court, the tribunal administratif of the property. That two-month court deadline is recalled word for word in Conseil d’Etat decision no. 450377 of 22 November 2021, which quotes the procedural article as follows:
“L’action doit être introduite devant le tribunal compétent dans le délai de deux mois à partir du jour de la réception de l’avis par lequel l’administration notifie au contribuable la décision prise sur sa réclamation, que cette notification soit faite avant ou après l’expiration du délai de six mois prévu à l’article R. 198-10” (Conseil d’Etat decision no. 450377 of 22 November 2021)
The same decision annulled a dismissal that had miscalculated that period during the health emergency, a reminder that judges count deadlines to the day. For a British claimant, two practical consequences follow. First, give the court a French address for service, an address in France where you can actually receive mail, or appoint a French representative, because court notices sent to a British address can arrive after the response window has closed. Second, never file the court claim before you have filed the prior complaint and received a rejection or waited six months: the court will declare a direct claim inadmissible, however strong the merits.
Three Brexit-flavoured scenarios illustrate the method. First, you exchanged contracts in November 2025, completed in December 2025, yet the 2026 bill arrives in your name as seller, or in the seller’s name if you are the buyer. File a correction request with the deed, ask for the cadastral record to be aligned, and, out of caution, file a protective complaint within the same letter citing articles 1400 and 1415. Second, your bill includes a new extension that was never built, or omits a demolition. File with the planning permissions, the completion certificates and photographs, and invite the administration to inspect. Third, your cadastral value looks indefensible next to neighbours’ bills. Ask for disclosure of your reference premises, propose identified better comparables in the commune with reasons, and invoke the Conseil d’Etat case law on comparison terms set out in part I. In each case, pay the 2026 bill by 15 or 20 October 2026 unless a formal stay is granted, then pursue the complaint to recovery, because late payment penalties accrue while you argue.
British owners sometimes ask whether they can complain in English or from the United Kingdom courts. The complaint and any court application must be in French and before the French administrative court of the property. The United Kingdom guidance on living in France usefully reminds British residents of the practical need to register, access healthcare and regularise their administrative life in France, but it does not create any tax remedy. Only the French procedure described here can discharge or reduce the French bill. If the amount justifies counsel, instruct early, before the December 2027 guillotine, so that the factual bundle can be built while witnesses and documents are available.
Conclusion
The 2026 taxe fonciere rewards the methodical owner and punishes the passive one. The tax falls on whoever owned on 1 January 2026, on a halved cadastral value multiplied by local rates plus waste and flood levies, with payment due on 15 October 2026, or 20 October 2026 online, and complaints admissible until 31 December 2027. Most British second-home owners will not qualify for the age and benefit exemptions of articles 1390 and 1391, which require occupation as a main home and modest French reference income, but many can correct a wrong taxpayer designation, a wrong base, or a wrong levy when they complain precisely, with identified comparables and complete deeds. The two Conseil d’Etat decisions examined here show judges doing exactly that work: checking that comparison terms are identified and local in decision no. 421173, and counting the two-month court deadline to the day in decision no. 450377. File the prior complaint to the right office, in French, with numbered exhibits, pay on time, and keep a French service address. Done in that order, a challenge from Britain is not a handicap. It is simply a file that the administration and, if needed, the court can decide on the documents.
