Owning a French second home does not stop being a French tax matter because the owner lives in Britain, has no French salary or spends only a few weeks a year in the property. The taxe foncière, meaning the French annual property tax on built property, is normally charged because the property is in France and because the taxpayer holds the relevant ownership right on 1 January. Brexit has not removed that local tax. It has, however, made the practical file more cross-border: the owner may need to obtain French cadastral documents, communicate with a French tax office from the United Kingdom and separate the tax itself from the tax on occupation, rental income and refuse collection.

A vacant or damaged house is not automatically exempt. A genuine claim may exist where a property normally intended to be let has remained vacant for at least three months for reasons outside the owner’s control. A different claim may concern a wrong surface, category, annex or physical description used to calculate the valeur locative cadastrale, the cadastral rental value used as the tax base. This article sets out the distinction, the evidence a UK owner should gather, the statutory deadline and the route for challenging the bill. It also explains why an ordinary holiday home, a renovation project chosen by the owner and a property that is simply unused do not necessarily produce the same result.

I. Why a UK owner may receive taxe foncière and when the bill can be challenged

A. Does a British owner pay French property tax on a second home?

The starting point is the location of the built property, not the nationality or tax residence of its owner. Article 1380 of the French General Tax Code states: “La taxe foncière est établie annuellement sur les propriétés bâties sises en France”. In English, the rule establishes the tax annually on built properties situated in France, subject to statutory exemptions. A British owner of a house in Normandy, Brittany, the Dordogne or any other French département therefore begins with a liability even if the owner is resident in the United Kingdom and the house is furnished only for personal visits.

The date rule is equally important. Article 1415 of the French General Tax Code provides that the relevant local taxes are established for the whole year according to the facts existing on 1 January. The practical consequence is that a sale completed in March normally does not transfer the public-law liability for that year to the buyer. A private sale agreement may apportion the economic cost between the parties, but that private adjustment is not the same thing as changing the tax debtor shown by the French administration. The same date can matter where a house became unusable after 1 January: the chronology must be proved rather than assumed.

The British Government’s Living in France guidance is useful for the post-Brexit residence context, but it does not turn a French property into a UK tax jurisdiction. A residence permit, a visit visa, settled status in Britain or the absence of a French residence permit does not itself cancel a local tax attached to French land and buildings. The France–UK tax treaty may matter for income, pensions, gains or the allocation of taxing rights on particular receipts. It should not be used as a general answer to a French local-property-tax notice. A UK owner should therefore analyse the taxe foncière on its own legal basis before considering any separate UK reporting.

Several charges can appear on the same notice and should not be merged. The taxe foncière sur les propriétés bâties is the property tax on the building. The taxe d’habitation sur les résidences secondaires is a different charge connected with furnished occupation of a second home. The taxe d’enlèvement des ordures ménagères, usually called TEOM, is the household-waste collection charge often shown with local taxes. A recent article on taxe d’habitation for UK owners of a French second home addresses the occupation tax separately. A successful challenge to the property-tax base does not necessarily erase every other line on the notice.

For a non-resident owner, the first practical document is the complete avis de taxe foncière, not merely the amount copied into a spreadsheet. Keep the notice showing the property reference, commune, tax year, payment date, account details and any separate TEOM line. The address used by the tax authority should also be checked. A notice sent to an old UK address, a French agent or a previous owner can create a communication problem, but failure to receive the notice is not normally a substitute for challenging the underlying assessment. The owner should update contact details through the French tax account or contact the service named on the notice.

B. Which error or vacancy situation creates a real legal route?

There are three different legal routes, and a claim is stronger when it identifies the correct one. The first concerns liability: the wrong person may be shown as owner, an usufruct may have been omitted, the property may have been transferred before the relevant date or a duplicate assessment may exist. The second concerns the tax base: the administration may have used the wrong surface, category, annex, equipment or physical characteristics. The third concerns a statutory relief for vacancy. The third route is narrow and should not be presented as a general “uninhabitable house exemption”.

Article 1389 of the French General Tax Code permits a dégrèvement, meaning a reduction or cancellation of tax for the qualifying period, in the case of “vacance d’une maison normalement destinée à la location”. The same provision requires three conditions: the vacancy must be independent of the taxpayer’s will, must last at least three months and must affect the whole property or a part capable of separate letting. The relief runs from the first day of the month after the vacancy begins to the last day of the month in which it ends. The rule is therefore concerned with a house normally offered for rent, not every second home that happens to be empty.

This distinction matters to a British couple who bought a house for weekends and then decided not to use it while the roof was being repaired. If the property was never intended to be let and the works were a voluntary improvement project, Article 1389 may not provide the desired relief. The same physical condition may be legally different where the house was genuinely offered to tenants, a serious event made occupation or letting impossible, and the owner can show that the vacancy was not chosen or prolonged by inaction. The evidence must demonstrate both the intended use and the owner’s efforts to prevent or end the vacancy.

Nor does the word “uninhabitable” resolve the question by itself. A municipal safety order, an expert report showing that water, electricity or structural safety is absent, or a building insurer’s report can be powerful evidence. But a tax office will still ask whether the house was normally intended for rental, whether the relevant part is separately lettable and whether the owner took reasonable steps. A property left empty because its owner prefers not to advertise it is not the same as a rental property that cannot lawfully or safely be occupied.

The second route is a calculation challenge. Article 1496 of the French General Tax Code says that the rental value of residential premises is determined by comparison with reference premises in the same commune and that the weighted surface is adjusted for the nature of the different parts, their situation, importance, condition and equipment. That is why a wrong garage, loft, pool, veranda, outbuilding or declared living area can affect the assessment. A UK owner should not assume that the amount is fixed by the purchase price. The purchase price and the cadastral rental value are different concepts.

Article 1517 of the French General Tax Code requires annual recording of new constructions, changes in consistency or use, and changes in physical or environmental characteristics. If a tax bill suddenly increases after a renovation, the issue may be a legitimate update, an incorrect declaration or a misread cadastral record. The correct request is to obtain the underlying evaluation details and compare them with the actual building. A UK owner should identify each disputed line instead of asking for a vague cancellation.

Where the property or a part has been placed in the wrong valuation regime, Article 1498 of the French General Tax Code provides the rules for built properties other than residential premises covered by Article 1496 and certain special categories. That provision can become relevant for a mixed-use building, an independent commercial unit or an annex that the administration has not treated as an ordinary dwelling. The classification should be checked before a British owner relies on a residential calculation. The claim should say whether the dispute concerns a home, a separate annex or a non-residential part.

In short, an empty holiday home is usually a liability question, an incorrectly described property is a valuation question and a rental house empty for reasons outside the owner’s control may be a vacancy-relief question. Those routes can overlap, but they do not require the same documents. The first stage of a good file is to label the route accurately.

II. How to build and file a winning claim from the UK

A. What evidence and calculations should accompany a réclamation?

A réclamation is a formal tax claim asking the administration to correct or reduce an assessment. It is more useful than an informal telephone conversation because it fixes the dispute, the tax year and the relief requested. A UK owner should create a chronology with four dates: the date of ownership on 1 January, the date the property became vacant or unusable, the date the three-month minimum was reached and the date the problem ended or was still continuing when the claim was filed. If the argument is a wrong valuation, add the date of the relevant works, declaration or change in use.

For a vacancy claim under Article 1389, the evidence should address intention, independence and duration. Useful documents may include:

• the title deed or land-register extract showing ownership and the nature of the right held;
• the complete tax notice and the French property reference;
• a letting mandate with a French estate agent, dated advertisements, viewing records, tenant enquiries and proof that the asking rent was adjusted where the market required it;
• an expert report, insurer’s report, municipal order, contractor’s report, dated photographs or utility records showing why the house could not safely or lawfully be let;
• quotes, invoices, planning correspondence, requests to a builder or insurer and evidence of steps taken to make the property usable again;
• proof that the owner did not occupy the property personally during the period relied upon, where personal use is relevant to the explanation; and
• a month-by-month calculation showing the relief requested, the undisputed balance and any TEOM or other charge that is not included in the request.

The chronology should be realistic. A single email to an agent after the property has already been empty for a year will not necessarily prove active marketing throughout that year. Conversely, the decision of the Conseil d’État in 5 June 2020, no. 423066, is helpful because it explains that the involuntary character of the vacancy is assessed by looking at the circumstances and the steps taken by the owner. The court stated that “le caractère involontaire de la vacance s’appréciant eu égard aux circonstances” and the owner’s démarches. It also held that putting a property up for sale did not automatically destroy the claim when the owner was still genuinely seeking tenants. For a UK owner, the lesson is to preserve rental adverts and agency instructions even if a sale is later considered.

A more difficult recent example appears in the Conseil d’État decision of 28 July 2025, no. 499919. The property had serious defects and required works. The court upheld the refusal because the owner had not shown sufficient steps to seek tenants or to end the vacancy in the circumstances examined. The decision records that the taxpayer bore the proof issue and that the tribunal had not committed an error of law. The short passage “la preuve, qui lui incombait” is a useful warning: photographs of damage are important, but they should be accompanied by evidence of the steps taken and the intended rental use.

For a calculation challenge, request the fiche d’évaluation, meaning the tax office’s property-evaluation sheet, and compare it with the actual property. Check the weighted surface, room category, number and type of annexes, heating, sanitary equipment, garage, cellar, loft, veranda, swimming pool and any other feature included. Ask whether a physical change has been recorded under Article 1517 and whether the property has been placed under the correct residential or non-residential method. An English-language explanation can be attached, but the core request should identify the French property reference and the exact box, surface or feature disputed. If the tax office requests a certified French translation of a UK report or deed, obtain one rather than sending an unexplained scan.

Calculate the requested relief conservatively. If the property qualified for vacancy relief from 15 February, Article 1389 does not normally produce a full-year cancellation: the statutory period begins on the first day of the following month and ends in the month in which the vacancy ceases. If the property became uninhabitable on 1 January but was not normally intended to be let, the date alone does not create the relief. If only a separately lettable annex was vacant, explain why it is capable of separate letting. If the notice includes TEOM, identify whether the request covers it; do not assume that a property-tax reduction removes every waste-collection charge.

A tax calculation can also be wrong without any vacancy. The tax base may include a surface that does not exist, an annex removed years earlier, or equipment never installed. The Service-Public guidance on challenging local taxes explains that a taxpayer may use the secure messaging service on impots.gouv.fr and can ask the tax office for the details used to establish the cadastral rental value. That official route is particularly useful for a UK owner who cannot attend the local office in person.

B. Which deadline, channel and court apply?

The deadline must be calculated before the substance of the file is polished. Article 1389 expressly sends the claimant to Article R*196-5 of the French Tax Procedure Book for a vacancy claim. The official text of Article R*196-5 uses the rule that the relief must be requested no later than 31 December of the year following the year in which the vacancy or non-operation reached the required minimum period. The Conseil d’État reproduced the same rule in 26 July 2018, no. 409385, together with the general local-tax claim rule in Article R*196-2. The decision quotes: “Les dégrèvements de taxe foncière prévus par l’article 1389 du code général des impôts” and applies the statutory deadline to the dispute.

That 2018 decision also shows why a dated claim matters. After a major flood had made the installations unusable for the remainder of the year, the Conseil d’État accepted a tax discharge for the qualifying period and recorded a sum of 14,823 euros. Its reasoning states that “la totalité des installations de la centrale hydroélectrique a été rendue inexploitable durant le reste de l’année pour un motif indépendant de la volonté de son propriétaire”. The case concerned an industrial installation, not a British holiday home, so it is not a ready-made entitlement for a residential owner. It does show how the court analyses an external event, the duration and the amount of relief rather than treating a damaged property as automatically exempt.

Submit the claim through the secure messaging service in the owner’s French tax account where possible. The official impots.gouv.fr explanation for an empty or vacant house confirms the Article 1389 route and the 31 December deadline. Select the tax year and the option relating to an error in the calculation or the property-tax assessment. Upload the notice, the evidence and a short calculation. If the online account cannot be used, send a signed written claim to the service identified on the notice, retain proof of dispatch and ask for an acknowledgement. A British owner should keep the original files, the upload receipt and the exact message submitted.

The claim should state four things in its first page: the taxpayer’s full name and address, the French property reference, the tax year and the precise outcome requested. Then identify the legal basis, the dates and the supporting documents. For example, a claim may ask for a partial dégrèvement under Article 1389 for the months after the three-month period, or a correction of the cadastral rental value under the provisions governing the valuation method. It should not simply say that the owner is British, that Brexit caused the problem or that the house was not used. Nationality and non-use are context; the legal ground is vacancy, valuation, liability or another identified exemption.

If payment is difficult while a genuine claim is being examined, Article L. 277 of the French Tax Procedure Book provides a mechanism for deferring the contested part when the taxpayer expressly requests it in the claim and states the amount or bases of the reduction sought. The official text says: “Le contribuable qui conteste le bien-fondé ou le montant des impositions mises à sa charge est autorisé” to defer the contested payment under the statutory conditions. This is not an automatic suspension. The request must be explicit, the uncontested amount should be separated and guarantees may be required for a claim above the regulatory threshold. Until the tax office confirms the position, the owner should not assume that a complaint alone prevents collection measures.

A refusal should be read carefully. The administration may reject the claim because the house was a personal second home rather than a rental property, because the vacancy was considered voluntary, because the three-month period was not reached, because only part of the building was affected without separate letting capacity, because the evidence was insufficient or because the deadline had passed. Each reason requires a different response. A valuation refusal calls for the evaluation sheet and a technical comparison. A vacancy refusal calls for letting evidence and the owner’s steps. A time-bar objection calls for the submission date and the statutory calculation. Repeating the same general explanation is rarely enough.

Local-tax litigation belongs to the administrative courts. The Conseil d’État decision in 2 December 2019, no. 426847, illustrates the procedural setting and explains that a dispute over a commercial part of a property may require a different valuation method from residential premises. It records a challenge to a refusal of relief for vacancy or non-operation and annulled the first-instance judgment on a procedural ground. The decision is not a British-owner exemption, but it confirms why the nature and use of each part of a mixed property must be described accurately. A first-instance challenge is normally brought before the competent tribunal administratif, with the precise court and time limit checked from the administration’s decision and the applicable tax procedure.

The remote file should therefore be assembled as if a French judge may read it months later: numbered exhibits, a one-page chronology, the disputed amount, the exact tax year, the official notice, proof of rental intention, technical evidence, proof of action and proof of timely submission. If the property is held through an SCI, the French civil property company, the company’s ownership and authority to act must be checked separately; this article does not replace advice on company formation or the purchase process. If the UK owner also receives rent, pension income or other foreign income, the property-tax claim should be kept separate from the income-tax return. The existing guide on a first French tax return after moving from the UK can be used for that broader tax-residence context.

Conclusion

A UK owner should not challenge a French taxe foncière by relying only on the fact that the property is empty, damaged or used as a holiday home. First identify whether the issue is ownership on 1 January, an incorrect cadastral valuation or a genuine vacancy of a house normally intended to be let. Then build the file around the statutory test: an involuntary vacancy, at least three months, the whole property or a separately lettable part, and evidence of the owner’s efforts. For a wrong bill, obtain the evaluation details and compare every surface, category and feature with the building.

File the formal réclamation before the applicable deadline, use the tax office named on the notice or secure messaging, separate the property tax from TEOM and other local charges, and request payment suspension expressly if Article L. 277 is relied upon. The decisions in nos. 423066, 499919 and 409385 show that the result turns on dates, intended use, evidence and reasonable steps. A cross-border owner who presents those points clearly has a far stronger case than one who submits a general complaint about Brexit or non-occupation.
