You own a stone cottage in the Dordogne, a seaside flat in Brittany or a village house in the Luberon. You live in Manchester, Edinburgh or Bristol, you spend school holidays and long weekends in France, and every autumn a set of pale envelopes — or messages in your online tax account — arrives from the French tax administration. Since Brexit, British owners often open these bills with a knot in the stomach: does a second home in France now cost more in local tax, has the old taxe d’habitation (a local residence tax, explained below) really disappeared, and what happens if the French property is valuable enough to trigger a wealth tax as well? This guide answers those questions in one place, for a British reader, in plain English with every French term explained.
The short answer is that three separate taxes can apply to the same French second home, each with its own liable person, its own calculation and its own challenge route. The taxe foncière (the annual local property tax paid by the owner of a built property) is payable every year by the owner. The taxe d’habitation sur les résidences secondaires (the surviving form of the old residence tax, now payable only on furnished second homes and not on main homes) is payable on furnished accommodation kept at your disposal. And the impôt sur la fortune immobilière, known as IFI (the annual French tax on net property wealth above a statutory threshold), can apply to British residents and non-residents alike where French property forms part of a large enough property portfolio. Each bill can be checked and, where it is wrong, challenged from the United Kingdom without travelling to France, provided you use the correct procedure and keep evidence from the start.
I. What you pay each year on a French second home — and who is liable for each bill
A. How taxe foncière and the second-home taxe d’habitation actually work for British owners
The taxe foncière sur les propriétés bâties (the annual tax on built property, covering houses, flats, gîtes and most outbuildings) is the most predictable of the three bills. The Code général des impôts (the French general tax code) 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 Code général des impôts). In ordinary language, every built property in France generates a taxe foncière bill each year unless a specific statutory exemption applies, and Brexit changed nothing in that principle: a British owner pays on exactly the same basis as a French owner of the same house.
The amount is driven by the valeur locative cadastrale (the cadastral rental value, a notional annual rent recorded for the property by the land registry and revalued nationally each year), multiplied by tax rates voted locally by the commune (the municipal council), the intercommunal body and, historically, the département (the county-level authority). Two identical houses in different villages can therefore produce very different bills, and a British buyer comparing a cottage in the Lot with a flat in Annecy should compare the local rates before exchanging contracts, because the rates follow the property, not the nationality of the owner. The bill, called an avis d’imposition (the formal tax assessment notice), arrives in the autumn in the online account on impots.gouv.fr (the official website of the French tax administration) or by post where no online account has been opened, and it names the owner recorded at the land registry.
The second bill surprises many British owners, because the taxe d’habitation (the old residence tax once paid by every occupier) was abolished for main homes but kept for second homes. The current text is explicit: “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” (Article 1407 of the Code général des impôts). Any furnished dwelling kept as somewhere other than a main home falls in principle within the tax, including a British-owned holiday cottage that stands empty for part of the year. Unfurnished, uninhabitable shells are a different analysis, but a normally furnished second home occupied for holidays is squarely within the charge.
Liability follows occupation rather than ownership, but for a second home the two normally coincide. The statute provides that “La taxe est établie au nom des personnes qui ont, à quelque titre que ce soit, la disposition ou la jouissance des locaux imposables” (Article 1408 of the Code général des impôts). The person who has the use or enjoyment of the premises is billed. Where a British family keeps its own furnished cottage at its own disposal, that family is the liable occupier. Where the same cottage is let year-round to a long-term tenant, the tenant becomes the occupier for this tax while the owner remains liable for the taxe foncière, so the two bills point at two different people. Short holiday lets sit between those poles and are examined in detail in Part II, because the decided cases turn on that exact distinction.
Both taxes are assessed on a single snapshot date. The code states that “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 Code général des impôts). A sale completed in March does not split the year’s bill: whoever owned or occupied on 1 January bears the whole year, subject only to any private price adjustment agreed with the buyer in the notarial deed of sale. British sellers and buyers should therefore check the 1 January position before completion and record any apportionment in writing, because the tax administration will pursue the person liable on that date.
On top of the base, many tourist communes vote a majoration (a statutory surcharge, currently capable of raising the second-home taxe d’habitation by a significant percentage) on second homes in areas with housing pressure. The surcharge does not apply everywhere; it depends on a published list of eligible communes and a local vote. A British owner with a flat in Paris, Lyon, Bordeaux, Biarritz or a ski resort should expect the surcharged figure and check the commune’s deliberation, while an owner in a quiet rural village with no housing shortage normally pays the un-surcharged amount. The distinction is purely geographic and has nothing to do with Brexit or nationality, but British owners concentrated in pressure zones feel it more often.
For the United Kingdom side of the picture, these French local taxes do not reduce a British tax bill. The France–United Kingdom double tax convention (the bilateral treaty allocating taxing rights between the two states) covers income tax and, for wealth, the IFI mechanism discussed below; it does not give a credit against United Kingdom tax for French taxe foncière or taxe d’habitation, which remain a final local cost of owning the French home. Guidance on residence and on reporting foreign property is published by HM Revenue and Customs on gov.uk, and the practical presentation of each French bill, with payment references and online payment, is described on service-public.fr. Budget for both French bills as a standing annual charge, distinct from income tax on any rental receipts.
B. When IFI, the French tax on property wealth, catches a British-owned French home
The third possible bill is national rather than local. The statute creates it in one sentence: “Il est institué un impôt annuel sur les actifs immobiliers désigné sous le nom d’impôt sur la fortune immobilière.” (Article 964 of the Code général des impôts). The IFI replaced the old ISF (the former wealth tax on all assets) and taxes only property wealth. The same article sets the entry threshold and the two categories of taxpayer. Persons domiciled in France for tax purposes (those whose tax home is in France under the statutory residence tests) are within the tax where the value of their property assets wherever situated exceeds 1,300,000 euros; persons without a French tax domicile are within the tax on their French property assets above the same threshold. A British owner living in Leeds with a single French cottage worth 400,000 euros is therefore outside IFI on that ground alone, while a British owner with a Paris flat worth 1,600,000 euros, or with several French properties whose combined French value crosses the line, must examine the charge carefully.
The base of the tax is defined as follows: “L’assiette de l’impôt sur la fortune immobilière est constituée par la valeur nette au 1er janvier de l’année” (Article 965 of the Code général des impôts). The net value of the property assets on 1 January counts, after deducting debts that satisfy the statutory conditions, and shares in property-rich companies count in proportion to the underlying French buildings. A British family holding a Provençal villa through an English company or a société civile immobilière, known as a SCI (a French non-trading property company commonly used by families to hold a shared house), does not escape the tax by interposing the company: the shares are taxed by reference to the French bricks behind them, subject to the detailed exclusions for small holdings in operating businesses set out in the same article.
Valuation follows inheritance-tax rules, with one well-known relief: “La valeur des actifs mentionnés à l’article 965 est déterminée suivant les règles en vigueur en matière de droits de mutation par décès.” (Article 973 of the Code général des impôts). The same article grants a 30 per cent reduction on the market value of a dwelling occupied as the owner’s main home. A British owner whose French house is a second home cannot claim that 30 per cent reduction on it, which is a frequent source of disappointment at the first IFI return: the reduction attaches to the main home only, and a holiday cottage is valued at its full market value. Debts are deductible only within strict limits, and loans taken out from the owner or from a controlled company to buy the taxable asset are disregarded in the situations listed in that article, so intra-family financing structures need careful review before the return is filed.
Split ownership needs equal care. French law frequently divides ownership into usufruit (a life interest or right of use and fruits, typically held by a surviving spouse or a parent) and nue-propriété (the bare ownership, typically held by children who will take full ownership when the life interest ends). The tax code provides that “Les actifs mentionnés à l’article 965 grevés d’un usufruit, d’un droit d’habitation ou d’un droit d’usage accordé à titre personnel sont compris dans le patrimoine de l’usufruitier ou du titulaire du droit pour leur valeur en pleine propriété.” (Article 968 of the Code général des impôts). The life tenant is therefore taxed on the full value, except in the closed list of cases — legal surviving-spouse life interests and similar situations — where taxation is split between the life tenant and the bare owner in statutory proportions. A British couple who reorganised ownership after a death should check which branch of the article applies before anyone files.
New arrivals from the United Kingdom benefit from a time-limited softening. Persons who have not been fiscally domiciled in France during the five calendar years before establishing their French tax domicile are taxable only on French assets, and not worldwide property, until 31 December of the fifth year following establishment, under the same Article 964 of the Code général des impôts. A family moving from Kent to Lyon with a retained London house therefore counts only French property for IFI during those first years, which often removes the charge entirely at arrival. After the period expires, worldwide property returns into the base, and the London house must be valued alongside the French home.
The IFI also has a plafonnement (a statutory cap linking total French taxes to a percentage of income), whose detailed mechanics have generated litigation. In a 2018 ruling on a priority constitutional question about the cap, the Conseil d’État (the supreme court for administrative matters, including tax) examined the first paragraph of section II of Article 979 of the tax code, concerning the computation of the cap where capital gains are taken into account without regard to holding-period allowances (Conseil d’État, 12 October 2018, No 422618). The lesson for British owners is practical rather than theoretical: where income is modest relative to property wealth — a retired household with a valuable Paris flat and a small pension, for example — the cap computation should be checked line by line with an adviser, because the statutory formula does not simply mirror the income-tax calculation and the administrative commentary on it has itself been challenged.
Finally, the treaty position on IFI differs from the position on local taxes. The France–United Kingdom convention allocates the right to tax property wealth and provides relief against double taxation, so tax paid in one state on the same property capital is taken into account under the treaty method rather than paid twice in full. Keep the French IFI assessment, the valuation evidence and the United Kingdom return together: the credit mechanism works only where each figure is documented, and the two administrations do not exchange valuations automatically.
II. Paying the right amount — and challenging a wrong French property tax bill from the United Kingdom
A. Getting the bill right: the 1 January snapshot, short lets, cadastral value and who pays
Most successful challenges start from the 1 January rule quoted above. Because both local taxes are assessed on the position at 1 January (Article 1415 of the Code général des impôts), the first question is always factual: who owned the property on that date, who had its use, and was it furnished? A British owner who sold in February but receives the autumn bill for the full year is usually liable in law, with any sharing to be settled privately against the buyer under the sale deed. Conversely, a British buyer who completed in December and finds the seller was billed should check the deed’s apportionment clause before paying the seller anything, because the administration’s claim runs against the 1 January owner or occupier, not against whoever holds the property when the bill is printed.
Short holiday letting is the most litigated corner of the second-home tax. The Conseil d’État has held that the tenant of any taxable dwelling on 1 January is normally liable, but that where a furnished dwelling is put to seasonal or short-term letting, the owner remains liable where, on 1 January, the owner can be regarded as intending to keep use or enjoyment of it for part of the year: “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.” (Conseil d’État, 23 December 2024, No 492174). In that case, owners of three classified tourism gîtes (furnished holiday cottages registered as tourist accommodation) in Brittany, marketed for short stays including through online platforms, had been discharged by the lower tribunal, but the Conseil d’État quashed the discharge for error of law: the very freedom to accept or refuse short-stay bookings through the year showed, in the court’s reasoning, that the owners had intended from the start of the year to keep use of the cottages, with the court stating that such circumstances “sont à l’inverse de nature à établir, ainsi qu’il est dit au point 2, qu’ils ont entendu dès le début de l’année conserver la disposition ou la jouissance de leurs biens”.
The practical consequence for a British owner who lets a cottage on a holiday platform is direct. Occasional short letting does not move the taxe d’habitation onto the succession of weekly guests; the owner who controls the calendar stays liable. What the owner should instead verify is whether the dwelling was genuinely and continuously offered for letting in a way that leaves no personal use, whether a long winter let transferred occupation to a single tenant present on 1 January, and whether the cadastral description still matches reality. Screenshots of the letting calendar, the management contract with a local agency, utility consumption records and the dates of personal stays form the evidence bundle that decides these cases. Assertions without documents do not move the administration.
Cadastral value errors are the second great source of overpayment. The valeur locative cadastrale can be out of date after works: a ruin rebuilt, an attic converted, a swimming pool added, or conversely a building deteriorated or partly demolished. Owners should compare the description on the assessment (number of rooms, floor area bands, comfort elements, outbuildings) with the actual property and with the notarial measurement from the purchase. Where the description is wrong, a claim supported by the sale deed, the diagnosticeur’s floor plans (the surveyor’s measurement reports annexed to most French sales), dated photographs and, where useful, a short statement from the local builder, carries far more weight than a general complaint that the bill feels high. Neighbour comparisons help only where the neighbouring property is genuinely comparable in the cadastral sense, not merely similar in market price.
Exemptions and reliefs form the third check. New builds, certain energy-renovation works, properties of elderly or disabled occupiers for their main home, and specific rural or urban-policy zones can reduce or remove taxe foncière, but most of these reliefs attach to the main home or to narrow statutory categories and do not help a British-owned second home. Do not assume a relief: read the eligibility conditions on the assessment notice and on the official pages, and claim expressly where the conditions are met, because several reliefs require an application before a stated filing date rather than applying automatically. An unclaimed relief is not an administration error.
For IFI, the equivalent pre-filing checks are valuation, debt and household composition. Value each French property at its likely sale price on 1 January with comparable sales from local notaires (public officers who record French conveyancing and publish price statistics), deduct only qualifying loans, identify who holds any usufruit and whether the case falls inside the split-taxation list in Article 968 of the Code général des impôts, and confirm whether the household is within the new-arrival period in Article 964 of the Code général des impôts. Married couples, civil partners under a pacte civil de solidarité known as PACS (the French registered civil partnership), and cohabiting partners are taxed jointly for IFI, so the children’s minor property administered by the parents also enters the household base. File on the correct return — the special IFI return above the threshold or the income-tax return with the IFI annex — because filing in the wrong place generates penalties before the substance is even examined.
B. How to challenge a taxe foncière, taxe d’habitation or IFI assessment without travelling to France
French tax procedure requires a prior complaint to the administration before any court action. The regulation 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” (Article R*190-1 of the Livre des procédures fiscales). The Livre des procédures fiscales (the French procedural code for tax disputes) therefore imposes a mandatory first step: a written réclamation (a formal administrative complaint seeking discharge or reduction) addressed to the tax office of the place of taxation, setting out the tax, the year, the amount disputed and the grounds with supporting documents. A British owner can do this entirely from the United Kingdom through the secure messaging system of the online account on impots.gouv.fr, which is the recommended channel because it timestamps the complaint and links it to the assessment; a recorded-delivery letter to the centre des finances publiques (the local public finance office) shown on the bill is the alternative where no online account exists.
The complaint must identify the error precisely: wrong person taxed, dwelling unfurnished or uninhabitable on 1 January, tenant in place on 1 January, wrong cadastral description, relief wrongly refused, surcharge applied in an ineligible commune, IFI valuation excessive, qualifying debt wrongly added back, or household wrongly aggregated. Attach the evidence in the same sending: sale deed extracts, letting calendar and agency contract, tenant’s lease and 1 January occupation proof, photographs, measurement reports, loan agreements with amortisation tables, marriage or partnership documents, and proof of the date of establishment of French tax domicile for the new-arrival rule. The administration decides on the complaint, in whole or in part, and that decision opens the route to the court.
Jurisdiction then splits according to the tax. The code provides that “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.” (Article L199 of the Livre des procédures fiscales). Taxe foncière and taxe d’habitation are direct local taxes, so an unsatisfactory reply is taken to the tribunal administratif (the first-instance administrative court) for the area where the property lies. The same article continues: “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 disputes therefore go to the tribunal judiciaire (the civil court), not the administrative court, and sending the claim to the wrong court loses time. Check the appeal notice attached to the administration’s reply, which names the competent court, and follow it.
Time limits in tax litigation are strict and run from events such as assessment, collection or payment; the code organises them through provisions including Article L190 of the Livre des procédures fiscales, which governs the admissibility framework for complaints and related actions. Because the applicable starting point varies with the tax, the document and the procedural history, British owners should read the time-limit notice printed on each assessment and each reply, diary it immediately, and file early rather than testing the boundary. The decided cases contain no general indulgence for non-residents, for language difficulties or for Brexit-related confusion: a late complaint fails regardless of its merits. Where the deadline stated on the notice is unclear, filing the online complaint promptly and asking the office to confirm receipt preserves the position while the substance is assembled.
Payment while disputing deserves a clear decision. A réclamation does not automatically suspend collection, and enforcement can continue during examination unless a sursis de paiement (a formal request to defer payment pending the outcome, granted on conditions including, where required, security) is requested and observed. Owners who can pay without hardship often pay and pursue reimbursement, which avoids late-payment surcharges if the claim fails; owners who seek deferral must request it expressly in the complaint and comply strictly with its conditions. Either way, keep paying or formally deferring the undisputed part: disputing the surcharge does not justify withholding the base.
Evidence from the United Kingdom needs no translation where it is in English and self-explanatory (bank statements, platform calendars), but key cover letters should be in French or bilingual, short, and numbered to the exhibits. Give each exhibit a number, refer to it in the letter, and keep a complete copy of everything sent with proof of sending. Where valuation is the issue, a French agent’s appraisal is useful but a notaire’s comparable-sales extract carries more weight; where occupation on 1 January is the issue, contemporaneous records beat reconstructions written for the dispute. And where the same point affects several years, file a separate complaint for each assessment year rather than assuming one letter covers all years.
Finally, keep the two countries’ files consistent. An IFI valuation argued in Paris should match the value declared for the same property in the United Kingdom where relevant, a letting position argued for taxe d’habitation should match the rental income declared in France, and the treaty relief claimed in London should rest on the same figures as the French assessment. Inconsistency between the two files is the fastest way to turn a winnable valuation dispute into a credibility problem on both sides of the Channel.
Conclusion
A British second home in France carries three possible annual tax layers: the owner’s taxe foncière on the building, the occupier’s taxe d’habitation where a furnished dwelling is kept as somewhere other than a main home, and the household’s IFI where net French — and, for French residents outside the new-arrival period, worldwide — property wealth crosses 1,300,000 euros. Each layer turns on a small number of verifiable facts: the 1 January position for the local taxes, the cadastral description and the commune’s surcharge vote, and the 1 January valuation, qualifying debt and household aggregation for IFI. The Conseil d’État’s 2024 gîtes ruling shows how strictly the courts read the 1 January intention test for short lets, and the IFI articles show how narrowly the valuation and split-ownership reliefs are drawn. Check those facts against the assessment every autumn, complain first to the tax office through the correct channel with numbered evidence, and take an unsatisfactory reply to the correct court — the administrative court for the two local taxes, the civil court for IFI. Done methodically from the United Kingdom, that discipline converts an anxious pile of French bills into a controlled annual routine.
