Receiving a French taxe foncière sur les propriétés bâties (French property tax on built property) is normal for a British owner of a house or flat in France, even when the property is empty and even when repairs have made it difficult to use. It is not, however, a tax bill that must simply be accepted. A wrong owner, an incorrect floor area, an outdated classification, an excessive maintenance coefficient or a qualifying period of involuntary vacancy can all justify a reduction or repayment. The practical difficulty is choosing the correct legal route: a reduction of the cadastral rental value is not the same claim as a vacancy relief under Article 1389 of the French General Tax Code.

For a UK owner, the Brexit context does not create a separate rate or a nationality-based exemption. The French property, its legal owner on the relevant date, its condition and the local rate control the assessment. The fact that you live in Britain, receive a UK pension or pay UK tax does not remove the French charge. It does mean that the evidence, correspondence and deadline often have to be managed across two countries. This article explains how to test the bill, assemble a defensible file and challenge the assessment before the claim expires.

I. Why is French taxe foncière wrong for a UK owner?

A. Which owner, property and valuation rules apply on 1 January?

The first question is not whether the bill looks high compared with a neighbour’s bill. It is whether the French tax authority has applied the right legal facts to your property. Article 1380 of the Code général des impôts (French General Tax Code) establishes the annual tax on built properties located in France, subject to statutory exemptions. The governing text is deliberately territorial: a British passport, a British bank account or a non-French correspondence address does not change the fact that a French building is within the French local-tax system. The official Service-Public TFPB guidance likewise starts from ownership or usufruct of a built property, not from nationality.

In practice, check the person named on the assessment and the legal position on 1 January of the tax year. A full owner, an usufructuary and a person holding a particular long lease do not occupy the same legal position. A sale during the year generally does not lead the tax authority to divide the assessment automatically between buyer and seller. The sale deed may provide a private reimbursement between the parties, but the tax roll still needs to be examined against the person legally liable for the relevant year. If the property is held through a French société civile immobilière (SCI, a civil property-holding company), the company’s liability and the individual shareholder’s position must not be confused. A previous article on French property-tax liability for a UK family SCI is relevant where the dispute concerns the company itself rather than the physical state of the building.

The second question is the tax base. Article 1388 of the General Tax Code provides that built-property tax is based on the property’s valeur locative cadastrale, meaning its cadastral rental value, with a statutory 50 per cent deduction intended to reflect management, insurance, depreciation, maintenance and repair costs. This is not the market value of the house and it is not simply the rent that you could obtain today. It is a fiscal rental value produced by a classification system, a measured or weighted surface, a category, a reference tariff and corrective coefficients. A high purchase price therefore does not prove that the tax is wrong, and a low current market rent does not by itself prove that the tax base must fall.

For a residential house or flat, Article 1496 uses comparison with reference premises in the same commune and category. Article 1495 requires each property or separately usable fraction to be assessed according to its physical composition, use, location and condition at the date of assessment. That is important for a British owner who bought an old farmhouse, a former barn, a maison secondaire or a partly converted building. The authority may have retained a description that no longer matches the actual premises: an annex can have been counted as living space, a room can have been treated as habitable, a floor area can have been entered twice, or a former professional use can have survived in the file after the property became residential.

Ask the centre des impôts fonciers (property tax centre) for the valuation sheet or the detailed information used to calculate the bill. Compare it with the title deed, plans, floor measurements, completion documents, photographs and the actual condition at the relevant time. Article 1406 of the General Tax Code requires owners to notify new construction and changes in composition or use within 90 days of final completion. That obligation should not be mistaken for a waiver of the right to correct an old error. A declaration made after renovation can explain a later increase, while a claim can still challenge an inaccurate historic description or a physical feature that the authority has never corrected.

Finally, separate the tax base from the local rate. The commune, intercommunality and other competent bodies vote rates that may rise even where the cadastral description is unchanged. A British owner who challenges only the percentage printed on the notice is usually attacking the wrong element. The stronger file identifies a factual error in the property record, a legally incorrect coefficient, a qualifying vacancy period or an arithmetic error in the calculation. The official Ministry of the Economy explanation of the calculation confirms the distinction between the cadastral base and the rate voted locally.

B. When does vacancy, damage or uninhabitability justify a reduction?

“The house is empty” is not, on its own, a legal ground for cancelling French property tax. The official impots.gouv.fr explanation of an empty house states that built-property tax remains due whether the premises are occupied or vacant, subject to specific conditions. The owner must therefore identify which of two different arguments applies.

The first is the special vacancy relief in Article 1389 of the General Tax Code. It concerns a house normally intended for letting, or an industrial or commercial building operated by its owner. The vacancy must be independent of the owner’s will, last at least three months and affect the whole building or a part capable of being let or operated separately. If those conditions are met, the relief begins on the first day of the month after the vacancy starts and ends on the last day of the month in which the vacancy ends. It is calculated by complete months, not by a daily pro-rata calculation.

The words “normally intended for letting” matter for a British owner. A furnished second home used by the family for holidays is not automatically a house normally intended for letting merely because it could theoretically be rented. The file should show a genuine letting intention: a mandate with an estate agent, an advert at a realistic rent, correspondence with applicants, a tenancy that ended, insurance for a rental property, or a documented decision to let after works. By contrast, a property kept solely for private use may not qualify for Article 1389 vacancy relief, even if it has been unused for a long period.

The reason for the vacancy must also be outside the owner’s control. A failed rental campaign at a realistic market price, a serious defect in the building, a dispute with a contractor, an order preventing occupation or major works imposed by a structural problem may support the claim. A refusal to rent because the owner prefers to wait for a higher price, a voluntary decision to keep the property empty or a lack of ordinary maintenance will make the condition harder to establish. Evidence should cover the date on which the qualifying situation began and the date on which it ended, not merely the fact that nobody slept in the property.

The Conseil d’État expressed this issue in decision no. 240857 of 9 April 2004. Its official summary describes Article 1389 as a mechanism for relief in the event of vacancy and states that the relief is subject to the condition that the vacancy be independent of the taxpayer’s will: “L’article 1389 du code général des impôts prévoit un mécanisme de dégrèvement de la taxe foncière sur les propriétés bâties en cas de vacance d’une maison normalement destinée à la location ou d’inexploitation d’un immeuble utilisé par le contribuable lui-même à usage commercial ou industriel. Ce dégrèvement est notamment subordonné à la condition que la vacance ou l’inexploitation soit indépendante de la volonté du contribuable.” The decision is available on Légifrance, Conseil d’État no. 240857. For an owner who lives in the UK, this is a reminder that a simple statement saying “I could not find a tenant” is weaker than a dated documentary record of a genuine letting process and an external obstacle.

The second argument is not Article 1389 at all. It is a challenge to the cadastral rental value or to the maintenance coefficient because the premises were incorrectly described or materially deteriorated. Article 324 Q of Annex III to the General Tax Code sets an entretien coefficient ranging from 1.20 for a building needing no repair to 0.80 for a building needing major repairs throughout. It describes a “passable” condition, coefficient 1, as permanent defects caused by age that do not compromise elementary habitability; a “mediocre” condition, coefficient 0.90, involves repairs of some importance, even if localised; and a “bad” condition, coefficient 0.80, involves major repairs throughout the building.

This classification does not mean that every leak, repainting job or cosmetic defect automatically lowers the bill. The relevant question is the condition of the construction and the repairs objectively required, supported by evidence connected to the tax year. In decision no. 418402 of 26 September 2019, the Conseil d’État held that, for the maintenance coefficient at the date of assessment, planned works must be taken into account when their necessity is established and their nature and cost reveal a need for repair: “Pour l’appréciation du coefficient d’entretien d’un immeuble à la date de l’imposition, doivent notamment être pris en compte les travaux envisagés dont la nécessité est attestée, dès lors que leur nature et leur montant révèlent le besoin de réparation de la construction.” The official text is available on Légifrance, Conseil d’État no. 418402.

The same decision also illustrates the danger of asking for a coefficient without proving the correct level of deterioration. Photographs showing some damp marks and a roof estimate may justify a re-examination, but they do not automatically establish the lowest coefficient. The claim should explain the building element affected, the safety or habitability consequence, the date, the technical diagnosis and the repair cost. An expert report is not always essential, but a coherent set of invoices, contractor quotations, insurance reports, municipal notices, photographs with dates and utility records is far more useful than general complaints about an old house.

Decision no. 474931 of 22 December 2025 provides a recent illustration of the distinction between the maintenance categories. The Conseil d’État stated that the “passable” coefficient is 1 rather than 1.10 and that 1.10 corresponds to an “assez bon” condition. Its official wording is: “le coefficient d’entretien applicable à un état passable est de 1, et que le coefficient de 1,10 correspond, selon les mêmes dispositions, à un état ‘assez bon’.” The court ordered the tax bases for several years to be recalculated using coefficient 1. The full decision, number 474931, is published by Légifrance. This is a useful authority where the administration accepts deterioration but places the property in a category that is too favourable to the building.

Do not confuse an uninhabitable property with a property that is merely unattractive or inconvenient. Structural instability, the absence of essential services, serious water damage, unsafe access or a building order may support a strong factual case. A kitchen that needs modernisation, old decoration, a poor view or a temporary lack of furniture normally will not. Nor does the fact that the property is subject to a separate taxe d’habitation or vacant-housing tax automatically remove taxe foncière. Each tax has its own legal conditions. The Service-Public guidance on vacant-housing taxes is useful for identifying that separate regime, but it should not be cited as if it created an automatic taxe foncière exemption.

II. How can a British owner challenge the bill and recover overpaid tax?

A. What evidence, deadline and administrative claim should you prepare?

Begin with a year-by-year schedule. Record the tax year, the date the assessment was put into collection, the amount of the built-property tax, the amount of any TEOM (French household-waste collection tax) included on the notice, the property address, the owner named on the notice and the precise ground of challenge. Do not send one undifferentiated complaint about “too much tax” for several communes or several legal grounds. A good schedule allows the tax office to identify the notice and allows you to calculate the relief requested.

For a valuation or maintenance-coefficient challenge, request the detailed valuation sheet and compare each component with the physical building. Check the weighted floor area, the number and nature of rooms, the annexes, the number of bathrooms and other comfort elements, the use of each area, the category, the reference premises and the maintenance coefficient. Article 1494 of the General Tax Code requires the rental value to be determined for each property or fraction normally intended for a distinct use. Article 1495 requires the property to be assessed by its composition, use, location and condition. Article 1496 explains the reference-premises method for residential premises. These three links should be cited in the claim because they show why a factual mismatch is legally relevant, rather than merely subjective.

Build the evidence in layers:

• identity and standing: title deed, share certificate or usufruct document, the tax notice and, where relevant, the SCI’s registration and authority to act;
• physical description: measured plans, photographs, videos, an architect’s note, a surveyor’s report and a room-by-room description;
• condition: dated photographs, invoices, quotations, insurance correspondence, fire or water reports, local-authority notices, expert reports and proof that repairs were necessary rather than optional;
• vacancy: the letting mandate, advertisements, applicant correspondence, termination notice, contractor timetable, utility readings, insurance record and a chronology proving at least three qualifying months;
• financial calculation: the exact coefficient or months claimed, the fraction of the building concerned, the amount of tax and the period for which a refund or reduction is requested.

For a vacancy claim, Article 1389 and Article R*196-5 of the Livre des procédures fiscales (French Tax Procedure Book) should be linked directly. Article R*196-5 states that the Article 1389 relief must be requested by 31 December of the year following the year in which the vacancy reaches the required minimum duration. The official Article R*196-5 text is especially important where the vacancy crosses two tax years. For example, a qualifying vacancy beginning in November may produce one full month for the first year and further full months for the next year, but the two claims do not necessarily share the same deadline.

For a general error in the local-tax assessment, current Article R*196-2 provides that a claim concerning local direct taxes must normally be submitted by 31 December of the year following the year in which the tax roll was put into collection, the relevant event occurred or the payment was made, depending on the situation. The version in force from 30 July 2026 is available at Article R*196-2 on Légifrance. Do not assume that the date printed on a British bank statement is the legal starting point. Use the date of the French tax roll or the date on which the event supporting a special reduction reached the statutory threshold.

Send a separate complaint for each commune. Article R*197-2 states: “En matière d’impôts directs locaux, une réclamation distincte doit être présentée par commune.” The direct official link is Article R*197-2. Article R*197-3 requires the claim to identify the tax, state the grounds and conclusions and include the notice or an equivalent document. Its official text is at Article R*197-3. A British owner with three French properties should therefore prepare three clearly identified claims, even if the same legal argument applies to each.

A non-resident owner must also plan the procedural address. Article R*197-5 states: “Tout réclamant domicilié hors de France doit faire élection de domicile en France.” The corresponding Légifrance text of Article R*197-5 matters for a British owner who remains resident in the UK. In practical terms, give the administration a reliable French address for the proceedings, or appoint a properly authorised French representative who can receive correspondence and provide the mandate. A French address for service is not the same thing as becoming French tax resident. It is a procedural safeguard designed to make the dispute operable.

The complaint can be submitted through the secure messaging service in the owner’s espace Finances publiques (online French public-finance account) or by a signed letter to the service responsible for the property. The official impots.gouv.fr complaint guidance confirms that a valuation dispute should be directed to the relevant individual tax service or property-tax centre and that a separate complaint is needed for each commune. Keep the submission receipt, the attachments, the notice and every response. A telephone conversation can help identify the right office, but it should not replace a written claim before the deadline.

Paying and challenging are separate decisions. A complaint does not automatically suspend collection. The French administration explains that the taxpayer may request a sursis de paiement, meaning a suspension of payment, at the same time as the claim. The request should identify the contested amount and acknowledge that guarantees may be required in some circumstances. If the claim is accepted after payment, the excess is refunded. If the claim is rejected and no suspension was requested, late-payment consequences may follow. The safest file therefore records both the legal challenge and the payment position rather than assuming that one cancels the other.

For the UK side, keep the French property-tax dispute separate from UK income-tax reporting. HM Revenue & Customs explains in its tax-on-foreign-income overview that overseas property rental income and overseas pensions can have UK reporting consequences, and that residence and double-tax relief may matter where income is taxed in more than one country. French taxe foncière is a local charge on the French property; it is not the same as UK Income Tax on rent or a UK Council Tax bill. A British owner should not argue that UK tax residence cancels French property tax, and should not use a French local-tax claim to resolve a separate UK tax-return issue.

B. What happens after refusal, and how should the dispute be escalated?

The tax authority may accept the claim, ask for missing evidence, make a partial reduction or reject it. A partial answer is not necessarily a failure: it may confirm the property record but refuse vacancy relief, or accept a lower maintenance coefficient but not the one requested. Read the decision ground by ground. Check whether the authority has addressed the year, the property fraction, the vacancy dates, the owner’s intention, the evidence of repairs and the requested calculation. If the answer is silent on a central point, request clarification while preserving the litigation deadline.

Article R*198-1 provides that tax claims are investigated by the tax administration and that cadastral surveyors participate in the investigation of taxe foncière claims. The relevant Article R*198-1 reference explains why technical evidence is valuable: the dispute may be checked against cadastral data and the physical characteristics of the building, not only against the owner’s narrative. Article R*198-3 also provides for the mayor’s opinion when a factual issue concerns taxe foncière; the authority’s internal consultation does not transfer the burden of proving the claim away from the taxpayer.

Article R*198-10 governs the administration’s decision period and motivation. It provides for a six-month period, with a possible additional period of no more than three months when the administration informs the taxpayer in time, and requires a partial or total rejection to be reasoned. The official text is available at Article R*198-10. A British owner should diarise the date of submission, the date of any request for missing documents and the date of the decision. An unexplained delay is not a reason to let the appeal period disappear.

If the administration’s decision does not give full satisfaction, Article L199 of the Tax Procedure Book allows a dispute concerning direct taxes and assimilated taxes to be brought before the administrative court. The official Article L199 text identifies the tribunal administratif as the competent court for this category of tax litigation. The claim is not a new informal email. It must identify the contested decision, the tax years, the property, the legal grounds, the evidence and the precise relief sought. The court will expect the prior administrative claim and the administration’s response to be produced.

The strongest litigation theory usually remains narrow. If the notice contains a wrong surface, prove the correct surface and show how the base changes. If the maintenance coefficient is too high, connect each major defect to the statutory scale and to the relevant year. If Article 1389 vacancy relief is sought, prove the letting purpose, the external cause, the three-month duration, the separately lettable part and the complete months claimed. Do not turn a property-tax case into a general complaint about French bureaucracy, Brexit or the overall cost of owning a house in France. The court decides the legal and factual grounds attached to the assessment.

The case law gives useful limits. In Conseil d’État decision no. 269884 of 25 November 2005, the court held that separate variations in the maintenance and location coefficients could not simply be added to create the required reduction in rental value; its official summary says that variations which, considered independently, do not reduce the rental value by more than one tenth cannot open the right to a relief. See Légifrance, Conseil d’État no. 269884. The lesson is to identify the legal mechanism and its threshold rather than combining every unfavourable feature into one broad percentage argument.

Conversely, CAA Marseille decision no. 00MA00759 of 18 December 2003 accepted a coefficient of 1 where the condition of the property, including necessary terrace-roof repairs, justified it under the statutory table. The official decision records that the condition of the building during the relevant years justified the coefficient under Article 324-Q. It can be read at Légifrance, CAA Marseille no. 00MA00759. This is useful for an owner whose building has serious but not total defects: the claim may be a lower coefficient, not a complete cancellation.

A court case should also address dates. A later quotation for works can be relevant evidence of a pre-existing condition, as decision no. 418402 shows, but the document should explain why the works were necessary at the tax date. A photograph taken after the notice is not worthless, but it must be tied to a chronology. A building survey, insurance report or municipal order that identifies when the defect existed is stronger. Keep original files with metadata where possible, together with certified translations only when the office or court needs them. English documents from a UK contractor should be accompanied by a clear explanation of the address, currency, work description and date.

The same discipline applies to an English-language owner’s correspondence. Use the French identifiers printed on the notice: the tax number, reference, commune, property address and year. State the legal grounds in French where possible, then provide an English explanation for the owner’s own records. Do not attach an unstructured bundle of hundreds of photographs. Create an index, label each photograph, link it to a defect and show the requested legal consequence. A short chronology and a calculation table can save more time than a long personal statement.

Lastly, consider the interaction with a mortgage lender, co-owner, insurer, tenant or SCI. A claim for a lower tax base does not decide who must bear the economic cost between private parties. A sale agreement, lease clause or shareholder arrangement may allocate tax payments differently. The tax office will not necessarily resolve that private allocation. Deal with the public-law assessment first, then preserve any contractual claim separately. Where the building is in a copropriété, distinguish defects in the private lot from defects in common parts and obtain the syndic’s reports, meeting minutes and calls for works. They can prove the condition and the repair timetable, but they do not by themselves establish Article 1389 vacancy relief.

Conclusion

A British owner can challenge French taxe foncière, but the claim must be built around the correct legal route. Ownership and the tax date come first. The cadastral rental value, property description and maintenance coefficient come next. Only then should you ask whether the special Article 1389 relief applies to a qualifying, involuntary vacancy lasting at least three months. An empty second home, a low market rent or the fact that the owner lives in the UK is not enough by itself.

The practical file should contain the notice, valuation sheet, title documents, measured plans, dated photographs, technical reports, repair quotations, letting evidence and a year-by-year calculation. Submit a separate claim for each commune, comply with the 31 December deadlines in Articles R*196-2 and R*196-5, provide a French address for service if you live abroad and ask expressly about payment suspension. If the answer is incomplete or negative, the administrative-court route under Article L199 remains available, subject to its own time limits.
