A British owner can sometimes obtain a reduction or refund of French taxe foncière when a rental property has remained genuinely and involuntarily vacant. Taxe foncière is the annual French local property tax charged on land and buildings. The relief is called a dégrèvement, meaning a statutory reduction of the assessment or a repayment of tax already paid. Brexit does not remove the claim, and British nationality does not create it. The decisive questions are whether the property was normally intended to be let, whether the vacancy lasted at least three consecutive months, whether it was outside the owner’s control, and whether the whole property or a separately lettable part was affected.

This is not an automatic exemption for every empty French house. A second home kept for personal use, a property held empty while its owner decides whether to sell, and a rental that was marketed only superficially can produce very different results. The evidence must show a real letting project, a credible response to the local market, and a continuous qualifying period. This guide answers the practical search questions that usually arise after a tenant leaves: can a UK owner claim, how many months can be reclaimed, what evidence is persuasive, and by when must the claim be made? It also separates the French local-property-tax issue from UK reporting of rental income or other foreign income.

I. Can a British owner claim French taxe foncière relief when a rental property is vacant?

A. What are the three conditions for an involuntary vacancy in France?

The starting point is that French property tax is attached to the French property, not to the owner’s passport. Article 1380 of the Code général des impôts (CGI), the French General Tax Code, 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.” The official provision is Article 1380 CGI. In plain English, a building situated in France is assessed every year unless a specific statutory exemption applies. A British owner living in London, Manchester, Paris or elsewhere therefore starts from the same French assessment rule.

The annual nature of the assessment is reinforced by Article 1415 CGI: “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.” The current text is available on Article 1415 CGI. The practical consequence is important: an empty property does not disappear from the tax roll merely because no tenant is present on the day an owner opens the bill. The owner must identify and invoke the specific relief for vacancy.

That specific provision is Article 1389 CGI. Its first paragraph sets out both the scope and the time window: “I. – Les contribuables peuvent obtenir le dégrèvement de la taxe foncière 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, à partir du premier jour du mois suivant celui du début de la vacance ou de l’inexploitation jusqu’au dernier jour du mois au cours duquel la vacance ou l’inexploitation a pris fin.” The official text is Article 1389 CGI. For the British owner of a residential rental, the relevant limb is the vacancy of a house normally intended for letting.

The same article imposes a cumulative test: “Le dégrèvement est subordonné à la triple condition que la vacance ou l’inexploitation soit indépendante de la volonté du contribuable, qu’elle ait une durée de trois mois au moins et qu’elle affecte soit la totalité de l’immeuble, soit une partie susceptible de location ou d’exploitation séparée.” Each part matters. “Triple condition” means that satisfying two requirements is not enough. The owner must be able to show all of the following:

• A rental purpose. The house must normally be intended for letting. The claim is not designed for a private holiday home that has never been offered to tenants. The owner should be able to show a prior lease, a mandate with a letting agent, a genuine advertisement, or a consistent history of rental use.
• At least three months. The qualifying vacancy must last for three months or more. The law works by complete months rather than a daily pro rata calculation. A short gap between two tenants will normally fail, even if it creates a noticeable financial loss.
• A sufficiently separate vacant area. The vacancy must concern the whole building or a part that could be rented separately. An unused bedroom inside an occupied house is not automatically a separately lettable unit. A self-contained flat, an independent annexe or a distinct commercial unit may be analysed differently, provided the factual layout supports separate use.
• Independence from the owner’s will. The vacancy must not be the result of the owner’s own commercial choice, an unrealistically demanding tenant selection policy, or a decision to leave the property empty while waiting for a preferred outcome.

The first condition is frequently misunderstood by non-resident owners. “Normally intended to be let” does not require the property to be occupied on every day of every year. It asks what the property is held and prepared for in the relevant legal and economic context. A tenant’s departure, the failure of a replacement tenancy, a sudden local-market contraction, a documented refusal by an insurer or a legal obstacle to letting may all be relevant. None is conclusive in isolation. The file must connect the event to the owner’s efforts to restore a lawful and realistic letting.

The third condition also prevents an owner from claiming a reduction for an incidental area. If a house has two independent flats and one flat cannot be let for the qualifying period, the claim may focus on that separate unit. If the owner simply keeps one room unused in a house occupied by family members, the legal character is less favourable. Floor plans, separate entrances, separate meters, prior leases and the property’s description in the land or letting records can make the difference.

Article 1389 also links the claim procedure to the procedural rules of the Livre des procédures fiscales (LPF), the French Book of Tax Procedures: “II. – Les réclamations présentées en application du I sont introduites dans le délai indiqué à l’article R*. 196-5 du livre des procédures fiscales et dans les formes prévues par ce même livre.” The reference to the claim is in the same Article 1389 CGI. The relief is therefore a formal tax claim, not a request that the tax office silently corrects the bill.

For a British owner, the first practical question should be: “What happened, on what date, and what did I do next?” A tenant giving notice is a clear starting event, but the file should then show the check-out, the condition of the property, the date it was made available, the instructions to an agent, the asking rent, viewings and the steps taken when the first strategy failed. This chronology is more useful than a bare statement that the house was empty.

B. Does a British passport, a seasonal letting or a planned sale prevent the claim?

British nationality does not by itself prevent relief. Article 1389 does not reserve the dégrèvement for French residents, French citizens or owners filing a particular immigration status. The property must be in France and the claim must satisfy the French tax conditions. Brexit may make the evidence and administration more cross-border, but it does not turn the vacancy test into an immigration test. A British owner should, however, keep proof of authority for any agent or representative acting in France, because a foreign address and an English-language file can otherwise make the chronology harder to verify.

A second home is a different starting point from a rental. The owner who visits for a few weeks, closes the shutters and does not seek tenants is generally dealing with a private-use property, not a house “normally intended to be let”. The distinction also matters because the taxe d’habitation on a furnished second home is a separate local tax. Article 1407 CGI begins: “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.” The official text is Article 1407 CGI. A successful vacancy claim for taxe foncière does not automatically cancel every other charge shown on a French tax notice.

Short-term or seasonal letting is not automatically excluded. In its decision of 14 April 2008, no. 289978, the Conseil d’État addressed a property let for short periods. The court stated: “la seule circonstance que leur propriétaire les loue pour de courtes durées ne fait pas obstacle à ce que les locaux litigieux soient regardés comme normalement destinés à la location” in Conseil d’État, 14 April 2008, no. 289978. The point is narrow but useful: the length of individual lettings is not, on its own, decisive. The owner still has to prove that the property was genuinely held out for rental and that the vacancy itself was involuntary.

The decision should not be turned into a blanket rule for holiday homes. A listing that is live only for a few days, a seasonal property that is occupied by its owner during the alleged vacancy, or a business model that intentionally leaves the property empty between selected bookings may all raise doubts. The file should identify the rental model, the normal letting season, the relevant local demand and why the gap went beyond the owner’s planned operating pattern.

A planned sale is also not an automatic bar, but it creates an evidential risk. In its decision of 5 June 2020, no. 423066, the Conseil d’État described the statutory test in these terms: “Ces dispositions subordonnent le dégrèvement de la taxe foncière sur les propriétés bâties à la condition, notamment, que la vacance de l’immeuble normalement destiné à la location soit indépendante de la volonté du propriétaire, le caractère involontaire de la vacance s’appréciant eu égard aux circonstances dans lesquelles cette vacance est intervenue et aux démarches accomplies par le propriétaire, selon les possibilités qui lui étaient offertes, en fait comme en droit, pour la prévenir ou y mettre fin.” The official judgment is Conseil d’État, 5 June 2020, no. 423066.

That judgment is important for an owner who listed the property for sale after a tenant left. A sale mandate does not automatically prove that the vacancy was voluntary. The court’s approach is contextual: what happened, what alternatives were legally and practically available, and what steps did the owner take to prevent or end the vacancy? A British owner may therefore preserve a claim by showing that the property was offered for rent at a realistic price while the sale was considered, or by explaining a documented legal or physical obstacle to a new tenancy. A file containing only a sale listing and no rental effort is much more vulnerable.

The opposite lesson appears in the Conseil d’État decision of 14 June 2017, no. 400351. The court repeated: “Le caractère involontaire de la vacance s’apprécie eu égard aux circonstances dans lesquelles cette vacance est intervenue et aux démarches accomplies par le propriétaire, selon les possibilités qui lui étaient offertes, en fait comme en droit, pour la prévenir ou y mettre fin.” See Conseil d’État, 14 June 2017, no. 400351. In that case, arguments such as a difficult market, limited maintenance and a single agency relationship did not establish an involuntary vacancy. The decision is a warning against treating market difficulty as evidence without contemporaneous proof of active, sensible efforts.

Tenant selection can cause the same problem. In its decision of 1 December 1999, no. 189656, the Conseil d’État held that “lorsque la vacance est la conséquence de la fixation, par le bailleur, de critères de conditions de ressources minimales, elle ne constitue pas une vacance indépendante de la volonté du contribuable”. The official decision is Conseil d’État, 1 December 1999, no. 189656. A British owner may of course carry out lawful solvency checks, but an empty property caused by criteria that are unnecessarily restrictive or disconnected from the local market may be treated as an owner-created vacancy.

Recent case-law should be read with care. In a 29 June 2026 order, no. 513256, the Conseil d’État refused to admit a challenge concerning a claimed involuntary vacancy; the operative ruling states: “Le pourvoi de M. C… n’est pas admis.” The official record is Conseil d’État, 29 June 2026, no. 513256. This is not a new automatic rule and it is not a substitute for analysing the facts. It does show why an owner who relies on the possibility of carrying out works or selling the property should preserve evidence of the concrete obstacles, the options considered and the action actually taken.

The answer to the search question is therefore yes, a British owner can claim, but not simply because the property was empty or the tenant stopped paying. The claim is strongest where the letting purpose is established, the vacancy period is continuous, the property or separate unit was genuinely available to rent, the asking terms were realistic and the owner can produce a dated record of attempts to secure a new tenancy.

II. How do you calculate and claim the French property-tax refund?

A. How much taxe foncière can be reclaimed, and from which month?

Article 1389 does not calculate the relief by the number of vacant days. It identifies a monthly window. The window begins on the first day of the month after the vacancy began and ends on the last day of the month in which the vacancy ended. The vacancy must reach at least three months before the statutory test is met. This means that a chronology built from exact dates is essential, but the final arithmetic is based on complete calendar months.

The practical summary published by the French tax administration confirms that taxe foncière remains due while a house is empty, subject to the statutory vacancy relief, and that the request is made by a claim to the public-finance office responsible for the property. It also explains the complete-month calculation and the treatment of associated charges. The official guidance is available at impots.gouv.fr: tax notice for an unoccupied or vacant house. The general public-service overview also places taxe foncière and second-home taxe d’habitation within French local taxes paid by the person who owns the property: see Service-Public.fr: local taxes.

Suppose a tenant leaves a separately lettable flat on 14 February and the next tenant takes possession on 20 June. If the owner proves that the vacancy was involuntary and that the flat was continuously offered for rent, the potential window under Article 1389 starts on 1 March and ends on 30 June. The qualifying period is therefore four complete months: March, April, May and June. February is not counted because the rule starts in the month following the beginning of the vacancy. The fact that the new tenant arrived on 20 June does not reduce June to twenty days for this calculation.

As a simple illustration, assume the relevant annual taxe foncière shown on the notice is €2,400. Four twelfths would be €800, subject to confirmation of the assessment and the exact dates. That is a calculation illustration, not a promise of recovery. The owner should not divide by 365, count the date of the check-out as a full month, or apply the relief to an unrelated tax. If the property is part of a larger building, the taxable basis and the separately assessed unit must be examined rather than estimated from the rent.

The notice may also include the taxe d’enlèvement des ordures ménagères (TEOM), the French household-waste collection tax. Article 1524 CGI provides: “En cas de vacance d’une durée supérieure à trois mois, il peut être accordé décharge ou réduction de la taxe sur réclamation présentée dans les conditions prévues en pareil cas, en matière de taxe foncière.” The official provision is Article 1524 CGI. The wording calls for a separate analysis of the waste-tax line; the owner should identify it and expressly ask the tax office how the reduction is to be applied instead of assuming that every line is reduced in exactly the same way.

Other items on a notice may have a different legal basis. A second-home taxe d’habitation, a local charge, a late-payment amount or a tax associated with a different property is not automatically covered by Article 1389. A claim should therefore reproduce the notice lines, the cadastral reference and the amount requested for reduction. Precision helps the Centre des finances publiques, the local French public-finance office, match the request to the correct assessment.

The annual assessment rule in Article 1415 also explains why an owner may receive a full bill even though the property was empty for most of the year. The tax office establishes the tax for the year on the facts existing on 1 January, then the taxpayer asks for the statutory vacancy relief afterwards. The two steps are not contradictory. Paying the bill, or arranging payment while the claim is reviewed, does not by itself waive the claim; the owner should keep proof of payment and ask for the relief by the formal route.

For an owner with a building containing several units, the calculation must follow the affected unit. Article 1389 requires the vacant part to be capable of separate letting. If the assessment is issued for the whole building, the owner may need to explain the proportion used, the unit’s independent features and the basis for the requested amount. An architect’s plan, a previous lease identifying the unit and a tax notice with a separate cadastral reference can be more persuasive than a calculation based solely on floor area.

A claim can also cover successive vacancy periods only if the facts support continuity or separate qualifying periods under the rule. A property cannot be described as continuously vacant if the owner used it personally, offered it as a holiday home, granted free occupation or allowed a tenant to occupy it informally. Keep a month-by-month schedule that identifies every occupation, proposed letting, repair, viewing and handover. If the period contains a genuine interruption, disclose it and calculate conservatively.

Finally, a refund calculation should be checked against the actual year and assessment. The amount of local tax can change from year to year, and the relevant notice may concern a different owner, parcel or unit. The best schedule has columns for the tax year, notice reference, annual amount, start of vacancy, end of vacancy, eligible calendar months, requested fraction and supporting document. That schedule turns a general complaint into an auditable claim.

B. What evidence and deadline should a British owner submit to the tax office?

The deadline is strict enough to put in the first line of the owner’s calendar. Article R*196-5 LPF states: “Les dégrèvements de taxe foncière prévus par l’article 1389 du code général des impôts pour vacance d’une maison ou inexploitation d’un immeuble à usage industriel ou commercial, doivent être demandés au plus tard le 31 décembre de l’année suivant celle au cours de laquelle la vacance ou l’inexploitation atteint la durée minimum exigée.” The official text is Article R*196-5 LPF. The relevant year is the year in which the vacancy reaches the required minimum, not necessarily the year in which the owner first notices the bill.

For example, if the three-month threshold is reached during 2025, the claim must be made no later than 31 December 2026 under that provision. The owner should not wait for a final tenant dispute, a sale, or an informal exchange with an agent before protecting the tax deadline. If documents are still being collected, a timely claim can identify the evidence available and explain that supplementary documents will follow, subject to the tax office’s instructions.

The claim is normally directed to the tax office identified on the assessment or through the official channel connected with that assessment. If the property is in more than one commune, the procedural rule matters. Article R*197-2 LPF states: “En matière d’impôts directs locaux, une réclamation distincte doit être présentée par commune.” See Article R*197-2 LPF. An owner with properties in different French communes should prepare separate claims rather than sending one general letter that leaves the local assessments unclear.

Article R*197-3 LPF lists formal elements required for a claim. It states: “Toute réclamation doit à peine d’irrecevabilité : a) Mentionner l’imposition contestée ; b) Contenir l’exposé sommaire des moyens et les conclusions de la partie ; c) Porter la signature manuscrite de son auteur ; à défaut l’administration invite par lettre recommandée avec accusé de réception le contribuable à signer la réclamation dans un délai de trente jours ; d) Etre accompagnée soit de l’avis d’imposition, d’une copie de cet avis ou d’un extrait du rôle, soit de l’avis de mise en recouvrement ou d’une copie de cet avis, soit, dans le cas où l’impôt n’a pas donné lieu à l’établissement d’un rôle ou d’un avis de mise en recouvrement, d’une pièce justifiant le montant de la retenue ou du versement.” The official wording is Article R*197-3 LPF. A British owner should therefore treat the signature, identification of the assessment and attachment of the notice as part of the legal task, not as administrative decoration.

The substantive purpose of the procedure is covered by Article L190 LPF. It describes contentious tax claims as those seeking either correction of errors in the assessment or calculation of tax, or the benefit of a right arising from legislation or regulation: “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.” The source is Article L190 LPF. A vacancy claim relies on the second type: the statutory right created by Article 1389, supported by facts.

Evidence should be organised around the three conditions and the dates. A useful file will normally include:

• The tax record: the full avis d’imposition, meaning the French tax notice, the property address, cadastral references, tax year, payment record and the line-by-line amount for the building or separate unit.
• The prior rental purpose: the former lease, inventory, rent receipts, an agency mandate, earlier advertisements, booking records if the model was seasonal, and documents showing that the relevant part of the property was independently lettable.
• The vacancy event: the tenant’s notice, termination agreement, check-out inventory, key-return record, insurance notification, court document, failed completion or other dated event that explains when the property became vacant.
• The market effort: advertisements with publication dates, the asking rent and revisions, agency correspondence, viewing appointments, applications, refusals, comparable local rents, and records of contact with more than one suitable agent where the first channel produced no result.
• The practical obstacle: contractor quotations, planning or safety documents, insurance correspondence, utility or access evidence, legal notices, photographs and reports if works or a regulatory obstacle made the property temporarily unlettable. The document must explain why the obstacle was outside the owner’s control and what the owner did to resolve it.
• The absence of owner-created vacancy: proof that the owner did not use the property personally during the claimed months, did not impose an unrealistic rent or tenant profile without market justification, and did not withdraw the listing merely because the preferred sale price was not achieved.
• The end of the period: the new lease, signed inventory, move-in record, keys, rent start date, or evidence that the property was lawfully reoccupied or returned to a genuine letting market.

Article 1353 of the Code civil, the French Civil Code, states the general burden-of-proof principle: “Celui qui réclame l’exécution d’une obligation doit la prouver. Réciproquement, celui qui se prétend libéré doit justifier le paiement ou le fait qui a produit l’extinction de son obligation.” The official text is Article 1353 Code civil. Tax procedure has its own rules, but the practical lesson is clear: do not assume the administration will reconstruct the letting history from a one-line statement that the property had no tenant.

English documents can be useful, especially where the tenant, insurer, lender or agent is based in the UK. Add a short French summary beside each important item. Identify the date, sender, recipient, property and legal significance. A tax office may ask for a French translation or additional formality for a particular document; do not describe a translation as universally mandatory or universally unnecessary. The goal is to make the evidence usable, while preserving the original file and its metadata.

The written claim should be concise even if the attachments are extensive. It can follow this order: identify the owner and property; state the tax year and notice number; describe the normal rental purpose; set out the vacancy start and end dates; explain why the vacancy was independent of the owner’s will; identify the separately lettable property or unit; calculate the eligible months and amount; invoke Article 1389 CGI and, where relevant, Article 1524 CGI; list the attachments; and request the reduction or repayment. The owner should sign it in the form required by the procedure and keep proof of sending and delivery.

A refusal should be read against the reason given. The tax office may dispute the rental purpose, the three-month period, the separate nature of the unit, the owner’s efforts, the amount, or the deadline. Those are different disputes and call for different evidence. A reply should not merely repeat that the property was empty. It should answer the precise reason, attach the missing proof and preserve the date of every exchange. If judicial proceedings or another time limit becomes relevant, obtain advice quickly rather than assuming that the administrative correspondence extends every deadline.

The French claim is also separate from the UK tax treatment of any rent. GOV.UK explains that foreign income can include rental income from overseas property and pensions, and that UK residents normally report foreign income under the applicable UK rules, with possible relief where income has been taxed twice. The official starting point is GOV.UK: Tax on foreign income; residence and split-year questions are addressed in GOV.UK: Tax on foreign income if you’re UK resident. A French taxe foncière reduction is a local-property-tax claim. It does not decide whether French rental income, a UK pension, a sale or another item must be declared in France or the UK.

If the property is being sold rather than kept in a genuine letting market, the analysis changes. Our related guide on challenging French capital gains tax on a second home as a British owner addresses that separate tax question. A sale strategy can appear in the vacancy evidence, but it should not be confused with the tax rules that apply when a French property is disposed of.

That separation is particularly important for a British owner who stopped letting the property but continues to receive a French tax notice. The vacancy relief concerns the property-tax assessment. It does not erase the prior rent, change the date on which income was received, or resolve residence under the France–UK tax treaty. Keep the property-tax evidence with the tax notice, but give rental-income and residence questions to the relevant tax adviser or lawyer with the full cross-border facts.

Before sending the claim, run a final quality check. Confirm that the vacancy lasted at least three consecutive months; confirm that the claimed period starts the month after the vacancy began; confirm that the property or part was separately lettable; reconcile the amount with the notice; check the 31 December deadline; prepare a separate claim for each commune where required; sign the claim; attach the notice; and retain a complete copy. These checks are especially valuable when a British owner is coordinating a French agent, a UK accountant and a local representative across different time zones.

Conclusion

A British owner can seek French taxe foncière relief for an involuntarily vacant rental property, but the claim turns on evidence rather than nationality. Article 1389 CGI requires a property normally intended for letting, a vacancy of at least three months, a vacancy independent of the owner’s will and a whole building or separately lettable part. The strongest file shows what happened after the tenant left, how the property was marketed, why the market response did not produce a new tenancy, and how the owner acted to end the vacancy.

Calculate by complete eligible months, not by vacant days. Use the actual tax notice, separate the lines that require their own analysis, and send the formal claim by 31 December of the year after the qualifying minimum was reached. Include the notice, signature, legal grounds, calculation and dated supporting evidence. A sale plan or seasonal model is not automatically fatal, but it makes the chronology and commercial evidence more important. If the administration refuses, address the stated reason and protect any further procedural deadline.

For a cross-border owner, the most efficient first step is to build one dated evidence bundle before writing the claim: lease and check-out documents, advertisements, agent correspondence, rent history, plans, works or insurance records, the tax notice and the month-by-month calculation. That bundle allows the French question to be answered on its own terms while keeping UK income-tax and residence issues separate.
