Every autumn the same envelopes land in British letterboxes, whether the house stands in the Dordogne, in Normandy or on the Côte d’Azur: the French property tax bills for the year, payable in full even though you live in Kent and spend only the summer in France. Brexit changed your residence permit, your health cover and your driving licence, but it changed nothing about these bills. French local property taxes are blind to nationality and to Brexit; they attach to the house, not to the passport, and a British owner of a French second home pays them on exactly the same basis as a French neighbour. What surprises British owners is not that the bills exist but how many of them there are, how each one is computed, and how fast a surcharge voted by the local council can inflate them. This article walks through the four yearly taxes a British second-home owner can face: the taxe foncière (land and buildings tax) every owner pays, the taxe d’habitation sur les résidences secondaires (second-home residence tax) with its surcharge of up to sixty per cent in tense areas, the tax on vacant homes for houses left empty, and the impôt sur la fortune immobilière (tax on real-estate wealth) for the largest estates. It then sets out the three remedies that challenge any of these bills: the formal claim to the tax office, the appeal to the administrative court, and the request for mercy when payment itself is the problem.

I. The two bills that find every British owner: taxe foncière and taxe d’habitation on second homes

A. Which property is caught, who is named on the bill, and why 1 January decides everything

The taxe foncière sur les propriétés bâties is the unavoidable yearly charge on built property. Article 1380 of the General Tax Code (code général des impôts), in force on Légifrance, 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.” Any house, flat or outbuilding standing in France is therefore caught unless a statute expressly exempts it, and the exemptions that matter, for new buildings or for disabled owners, are narrow and conditional. The person named on the bill is the owner as recorded at the land registry on 1 January of the tax year, and a sale completed in March does not move that year’s bill to the buyer: the seller remains liable for the whole year, subject only to a private apportionment clause in the sale deed, the prorata negotiated before the notaire (the French conveyancing solicitor who authenticates every sale). British buyers should therefore check the preliminary contract for that clause, because without it the January seller pays for twelve months of someone else’s ownership.

The second bill, the taxe d’habitation sur les résidences secondaires, falls on furnished homes kept for your own use rather than as a main home. Article 1407 of the same code, in force on Légifrance, provides: “I. – 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.” Your Dordogne farmhouse, furnished and lived in each summer, is the textbook case, while a bare ruin with no furniture or a unit used exclusively as professional premises escapes it. Since the abolition of the tax on main homes, this second-home version is the only taxe d’habitation left, which is why British owners hear French neighbours say the tax has disappeared while their own bill keeps arriving: the neighbour’s main home is exempt and your holiday home is not. The administration’s English-language guide, the service-public.fr page on housing tax on second homes, and the finance ministry’s explanatory page on how the second-home tax works both confirm the scope, the declaration of occupancy owners must file, and the calendar of assessment notices.

Both bills turn on a single photograph taken on 1 January, and the supreme administrative court, the Conseil d’État, enforces that rule with visible strictness. In CE, 8th chamber, 23/12/2024, No 492174, owners of three classified holiday gîtes in Brittany had beaten the bill before the Rennes court by showing the gîtes were let almost continuously through online platforms. The Conseil d’État annulled that discharge and restated the law: “I. La taxe est établie au nom des personnes qui ont, à quelque titre que ce soit, la disposition ou la jouissance des locaux imposables (…)”, and “La taxe foncière sur les propriétés bâties, la taxe foncière sur les propriétés non bâties et la taxe d’habitation sont établies pour l’année entière d’après les faits existants au 1er janvier de l’année de l’imposition”. From those texts it drew the working rule every British owner who lets out a gîte should memorise: “Il résulte de ces dispositions qu’est en principe redevable de la taxe d’habitation le locataire d’un local imposable au 1er janvier de l’année d’imposition. Toutefois, par dérogation à ce principe, lorsqu’un logement meublé fait l’objet de locations saisonnières ou de courte durée, le propriétaire du bien est redevable de la taxe d’habitation dès lors qu’au 1er janvier de l’année de l’imposition, il peut être regardé comme entendant en conserver la disposition ou la jouissance une partie de l’année.” Because the owners remained free all year to accept or refuse each booking as it came, they had kept disposal of the gîtes, and the bills stood. If you let your second home on a platform between your own stays, assume you owe the tax, and organise your challenge, if any, around the narrow question of whether on 1 January you had truly given up every personal use for the whole year. Readers who go further and let the house full-time will find the rental-side rules, registration, change-of-use permission and income tax, in our companion guide to renting out a French second home after Brexit.

B. How each bill is computed, and why the surcharge can add sixty per cent in tense zones

Neither bill is a flat fee; each is the product of an administrative rental value and a rate voted locally, which is why two identical houses ten kilometres apart can pay visibly different amounts. The starting point is the valeur locative cadastrale, the notional yearly rent the land registry attributes to the dwelling from its size, comfort and location, revalued each year by a national coefficient. The commune, the intercommunal body and, for the taxe foncière, the department each vote a percentage rate applied to that base, after a fifty per cent reduction for the foncière to reflect notional charges. British owners should therefore read a sudden jump in either bill in two steps: first check whether the cadastral base moved, then check whether the local council voted a higher rate. A wrong base, a demolished extension still on the plan, a swimming pool recorded twice, or a dwelling classed in the wrong comfort category, is challenged as an error of assessment through the remedies set out in the second part; a higher rate, however painful, is a lawful political choice and cannot be challenged on its amount, only on the legality of the vote itself.

The shock most British owners actually feel comes from the second-home surcharge, the majoration that tense-zone communes may pile on top of the taxe d’habitation. Article 1407 ter of the General Tax Code, in force on Légifrance, provides: “Dans les communes mentionnées au B du I de l’article 1406 bis, le conseil municipal peut, par une délibération prise dans les conditions prévues à l’article 1639 A bis, 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.” The communes entitled to vote it are those where housing demand structurally exceeds supply, essentially the Paris region, the Atlantic and Mediterranean coasts, the ski resorts and the large cities, and each year more councils join the list as the housing crisis spreads. Paris itself votes the surcharge, which matters for British owners of a pied-à-terre in the capital: the Paris bill already reflects some of the highest rates in France before any majoration, and the Île-de-France communes around it follow the same movement. Before buying, check the commune’s current deliberation, because the surcharge applies for the whole year on the 1 January situation and no personal circumstance, British residence included, exempts you from it. The only structural reliefs are narrow statutory cases, such as a second home kept for professional reasons near the workplace or an invalidity-linked situation, each with its own formal claim to file; the default position for a holiday home is the full rate plus the full surcharge.

Two practical consequences follow for the way British owners hold and use their houses. First, the declaration of occupancy, which the tax office now requires every owner to file online, designates each property as main home, second home or vacant, and that single click routes the file towards exemption, standard taxation or the vacancy track examined below. A wrongly ticked box generates the wrong bill automatically, so verify the status of every French property in your online account each January rather than discovering the error on the autumn assessment. Second, keeping a house permanently available for your own holidays has a yearly price that must enter the purchase arithmetic alongside the notaire’s fees and the agency commission: foncière plus habitation plus surcharge, repeated every year whether you visit or not. When that arithmetic turns negative, the exit route is the sale, whose own capital-gains bill for a UK-resident seller is mapped in our guide to selling a French holiday home as a UK resident after Brexit; the yearly taxes in this article and that sale-side tax together make up the full fiscal cost of the French second home.

II. The two taxes that catch only some owners, and how to challenge any of these bills

A. Empty homes and large fortunes: the vacant-home tax and the IFI for British owners

A house left continuously empty can attract a third bill on top of the first two, and the statute aims precisely at owners who keep homes off the market. The taxe annuelle sur les logements vacants, the yearly tax on vacant dwellings, is defined by Article 232 of the General Tax Code, in force on Légifrance: “I. – La taxe annuelle sur les logements vacants est applicable : 1° Dans les communes appartenant à une zone d’urbanisation continue de plus de cinquante mille habitants où il existe un déséquilibre marqué entre l’offre et la demande de logements entraînant des difficultés sérieuses d’accès au logement sur l’ensemble du parc résidentiel existant”. In those zones a dwelling vacant for more than a year, then two, is taxed at rising rates, and the vacancy is assessed in law, not in feeling: a house you visit two weeks a year is occupied, not vacant, while a flat left shuttered for eighteen months with the utilities cut is vacant even if you intended to renovate it. Outside those tense zones, communes may vote a local equivalent instead. Article 1407 bis of the same code, in force on Légifrance, states: “Les communes autres que celles visées à l’article 232 peuvent, par une délibération prise dans les conditions prévues à l’article 1639 A bis , assujettir à la taxe d’habitation sur les résidences secondaires, pour la part communale et celle revenant aux établissements publics de coopération intercommunale sans fiscalité propre, les logements vacants depuis plus de deux années au 1er janvier de l’année d’imposition.” The two systems therefore divide the country between them: the State vacancy tax in tense urban zones, the voted local vacancy charge everywhere else. A British owner renovating slowly should keep dated proof of genuine occupation or of works making the dwelling uninhabitable, because vacancy lasting years without evidence is taxed first and discussed later.

The fourth tax touches only the largest estates but does so regardless of residence, and British owners of fine Paris flats or Riviera villas meet it head-on. Article 964 of the General Tax Code, in force on Légifrance, opens: “Il est institué un impôt annuel sur les actifs immobiliers désigné sous le nom d’impôt sur la fortune immobilière.” It continues: “Sont soumises à cet impôt, lorsque la valeur de leurs actifs mentionnés à l’article 965 est supérieure à 1 300 000 €”. Above that threshold the rules split by residence. A British owner who lives in Britain is caught only on French assets: “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”. A British owner who has moved to France is caught on worldwide property, with one valuable bridge for newcomers: “les personnes physiques mentionnées au premier alinéa du présent 1° qui n’ont pas été fiscalement domiciliées en France au cours des cinq années civiles précédant celle au cours de laquelle elles ont leur domicile fiscal en France ne sont imposables qu’à raison des actifs mentionnés au 2°”, a five-year shelter for foreign property that runs until 31 December of the fifth year after settling in France. The base itself is net value at New Year: Article 965 of the same code, in force on Légifrance, states: “L’assiette de l’impôt sur la fortune immobilière est constituée par la valeur nette au 1er janvier de l’année”. Net means debts linked to the assets, such as the remaining mortgage on the Paris flat, reduce the base, while shares in property companies count up to the fraction representing the underlying buildings. Couples, married, pacsed or openly cohabiting, are taxed jointly, and the 1 January photograph governs here too. An owner hovering near the threshold should therefore value carefully, deduct qualifying debt, and file even in doubt, because omission draws penalties while a reasoned valuation merely invites discussion.

B. How to challenge the bill step by step: the claim to the tax office, the judge, and the request for mercy

A wrong local-tax bill is not a bill to pay first and debate later without method; it is a decision to attack through remedies that fit together, each with its own deadline, and missing the first deadline kills the others. French tax procedure is written, formal and unforgiving about time limits, so the order below is also a calendar to open the day the avis d’imposition, the printed tax bill, arrives. The scope of the ordinary remedy is set by Article L190 of the Tax Procedure Book (livre des procédures fiscales), in force on Légifrance: “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.” A wrong cadastral base, a gîte wrongly treated as kept at your disposal, a surcharge applied where no deliberation exists, an IFI valuation that ignores the mortgage: each is an error of base or calculation, or the denial of a statutory right, and each belongs to the tax courts. The first step is always the preliminary claim, the réclamation, sent to the tax office before any judge may be approached. Article R*190-1 of the same book, in force on Légifrance, states: “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.” The deadline is laid down by Article R*196-1, in force on Légifrance: “Pour être recevables, les réclamations relatives aux impôts autres que les impôts directs locaux et les taxes annexes à ces impôts, doivent être présentées à l’administration au plus tard le 31 décembre de la deuxième année suivant celle, selon le cas : a) De la mise en recouvrement du rôle ou de la notification d’un avis de mise en recouvrement”. Local taxes have their own parallel deadline in the same book running to the same 31 December of the second following year, so a 2025 foncière bill is claimable until the end of 2027, and the office must decide within six months, since Article R*198-10 provides that “La direction générale des finances publiques ou la direction générale des douanes et droits indirects, selon le cas, statue sur les réclamations dans le délai de six mois suivant la date de leur présentation”. File through your online account on impots.gouv.fr as well as by registered post from Britain, keep every receipt, and diary both the six-month mark and the December guillotine.

If the office rejects the claim expressly or lets the deadline expire, the second step is the administrative court, and here the clock runs brutally fast. Article R421-1 of the Administrative Justice Code (code de justice administrative), in force on Légifrance, provides: “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.” Two months from the rejection letter, not a day more, to lodge the application with the tribunal administratif of the property’s location, increasingly filed through the Télérecours online system, which a British non-resident can use with an empowered French representative. The application must identify the exact legal flaws: wrong cadastral rental value with a surveyor’s report and comparable assessments, misapplication of the 1 January rule with dated proof of sale, lease or works, absence or illegality of the surcharge deliberation with the council minutes, or IFI overvaluation with bank statements of the remaining loan. Ask the judge to discharge the assessment in principal and surcharges and to order repayment with default interest, and join every exhibit in an ordered, paginated bundle. Remember the standard the courts actually apply, shown by the Brittany gîtes decision above: the judge checks the 1 January photograph, and the taxpayer who kept disposal of the dwelling, even through flexible short lets, loses. Frame the file around that photograph from the first line of the claim, not as an afterthought at the hearing.

When the bill is legally correct but payment itself is the problem, or when only penalties remain in dispute, a third route exists that asks for mercy rather than for law: the demande gracieuse, the request for discretionary relief. Article L247 of the Tax Procedure Book, in force on Légifrance, provides: “L’administration peut accorder sur la demande du contribuable ; 1° Des remises totales ou partielles d’impôts directs régulièrement établis lorsque le contribuable est dans l’impossibilité de payer par suite de gêne ou d’indigence ; 2° Des remises totales ou partielles d’amendes fiscales ou de majorations d’impôts lorsque ces pénalités et, le cas échéant, les impositions auxquelles elles s’ajoutent sont définitives”. A British pensioner whose sterling income collapsed against the euro, or an owner hit by an IFI catch-up bill swollen with late-payment surcharges, writes to the same office setting out income, charges and assets with bank statements, and asks for remission of the penalties first and of the principal if hardship is genuine. Relief is discretionary and never a right, its refusal is reviewed only for manifest error, and it never suspends the ordinary claim deadlines, so it must run alongside the réclamation, never instead of it. Used in that order, claim for what is wrong, court for what the office refuses to correct, mercy for what remains genuinely unpayable, even a heavy second-home tax year ends with every lawful reduction extracted and every deadline kept.

Conclusion

Owning a French second home from Britain after Brexit means accepting a yearly fiscal season that no residence permit and no passport can cancel. The taxe foncière bills the owner recorded on 1 January, the taxe d’habitation bills whoever kept a furnished home at their disposal on the same date, the surcharge of up to sixty per cent rewards the communes where housing is scarcest, the vacancy taxes punish houses left to sleep, and the IFI takes its share above 1.3 million euros of net property, with a five-year bridge for newcomers and French-only exposure for non-residents. Each of these taxes is computed from a base, a rate and a date, and each of those three elements can be checked, which is what makes the system contestable rather than fatal. Check the occupancy declaration every January, photograph the 1 January situation as the administration will, verify the cadastral base and the council’s deliberation behind every jump, value the IFI base net of debt, and file the preliminary claim before 31 December of the second year, the court appeal within two months of any rejection, and the mercy request alongside rather than instead. A second home handled this way stops being a succession of surprises in the autumn post and becomes what it should be: a known yearly price, reduced wherever the law allows, for the house you chose to keep in France.
