Receiving a French vacant-home tax notice for a house or flat that you own from the United Kingdom can be unsettling, particularly when the property is used only during holidays, is being renovated, or is waiting for a tenant. Brexit does not create a general exemption for a British owner. The decisive questions are different: where the property is located, which tax regime applies, how long it was empty on 1 January, whether it was actually habitable, and what evidence you can produce.

For a 2026 assessment, the notice may concern the taxe annuelle sur les logements vacants (TLV, the annual tax on vacant homes) or the taxe d’habitation sur les logements vacants (THLV, the local tax on vacant homes). A reform enacted in 2026 creates a unified taxe sur la vacance des locaux d’habitation for assessments from 2027. The transition matters: a good argument under the old rules can be framed badly if it is attached to the wrong year or the wrong tax label.

This guide deals with the individual legal and tax position of a British owner living in France or holding a French home after Brexit. It does not address the purchase process, which belongs to the property desk, or the creation of a company. It explains how to identify the charge, build a dated evidence file, calculate the likely exposure, and challenge an assessment without losing a procedural right. The facts of the property and the wording of the notice should still be reviewed before a formal claim is sent.

I. Why can France charge a UK owner, and which vacant-home tax applies?

A. How TLV and THLV work for the 2026 tax year

The first point is territorial. French vacant-home taxes attach to the dwelling, not to the passport of the owner. A British national, a French national, and a company can therefore face different consequences according to the address and legal capacity in which the property is held, but British nationality by itself is not a defence. The person liable under the former TLV rule can include the owner, an usufructuary (a person entitled to use the property and receive its benefits), a construction or rehabilitation leaseholder, or an emphyteutic leaseholder. The formal wording is found in Article 232 of the French General Tax Code (the Code général des impôts, or CGI).

Under the version applicable up to 1 January 2027, Article 232 places TLV in communes, meaning French municipalities, where the housing market is considered materially unbalanced. The list is set by regulation. The legal trigger is not simply “I did not sleep there”. The text states: “La taxe est due pour chaque logement vacant depuis au moins une année, au 1er janvier de l’année d’imposition”. In English, the home must have been vacant for at least one year as at 1 January of the tax year. That reference date is often more important than the date on which the notice arrives.

The same article states that the tax is paid by the relevant holder of the property right. It is not a charge reserved for landlords who deliberately keep a rental unit off the market. A second home left empty between visits can be examined under the statutory conditions even where the owner pays French property tax, keeps insurance in force, and visits several times a year. A few weekends, a fortnight in August, or a caretaker’s occasional inspection will not automatically prove that the home ceased to be vacant for the legal period.

TLV should be distinguished from taxe foncière, the ordinary French property tax on built property and land. It should also be distinguished from the former ordinary residence tax, and from tax residence under the France–UK treaty. A person can be non-resident for French income-tax purposes yet still be liable for a French tax attached to a French building. Conversely, becoming French tax resident does not by itself make every French property a main residence or remove the vacancy analysis.

The charge is based on the property’s valeur locative, or cadastral rental value: a statutory rental-value figure used for local tax calculations, not necessarily the rent that an estate agent would obtain today. Article 1409 of the CGI describes the rental-value basis used for dwellings and their appurtenances. Under the former Article 232 regime, the statutory rate is 17% for the first year of imposition and 34% from the second year. The notice can therefore be materially higher when the administration treats the vacancy as continuous.

THLV follows a different geographical route. In a commune outside the TLV area, the commune can, subject to the required deliberation, impose the tax on a home vacant for more than two years at 1 January. The former Article 1407 bis of the CGI says that communes other than those covered by Article 232 may subject the dwelling to the residence-tax regime for secondary homes when the vacancy exceeds two years. The article expressly links the meaning of vacancy to the relevant paragraphs of Article 232. It is therefore not enough to read “THLV” and assume that the administration has applied a simple local council charge without the statutory vacancy test.

For a British owner, the practical distinction can be summarised as follows:

Question	TLV for the 2026 regime	THLV for the 2026 regime
Where?	Commune included in the national vacant-home area.	Commune outside that area which adopted the required local deliberation.
Vacancy period	At least one year at 1 January.	More than two years at 1 January.
Who is charged?	The owner or other statutory holder with the property at the start of the vacancy period.	The person liable under the local residence-tax rules.
What is the base?	The statutory cadastral rental value.	The statutory residence-tax base, subject to the local rules.

The table is a starting point, not a substitute for reading the notice. A French tax notice can contain a spelling variant of the address, a tax year that differs from the year of receipt, or an ownership record that has not followed a sale, inheritance, usufruct arrangement, or change of address. Check the tax type, year, commune, cadastral references, and named liable person before arguing about the reason for vacancy.

There is also a UK-side issue, but it is not a shortcut around the French assessment. The official GOV.UK guidance for people living in France explains that UK nationals may have continuing UK tax obligations and should consider the France–UK double-taxation agreement. That treaty can allocate or relieve certain forms of income taxation. It does not turn a French building into a UK building and does not, by itself, cancel a French vacant-home tax. Keep the French property file and the UK income or residence file separate so that a treaty argument is not used where the real issue is factual vacancy.

B. When is a property legally vacant, and what changes in 2027?

Vacancy is assessed by reference to the condition and use of the property, not just the owner’s intention. A property that is available for normal and durable occupation can be treated differently from a building that is not habitable, a home subject to a genuinely external obstacle, or a property whose use is supported by evidence even though it is not the owner’s main residence. The decisive evidence must usually relate to the relevant 1 January and the preceding reference period.

The former Article 232 regime includes an important safeguard. Its sixth paragraph says: “La taxe n’est pas due en cas de vacance indépendante de la volonté du contribuable”. This means that vacancy independent of the taxpayer’s will is not taxed. The sentence does not create a general exemption for every difficult or inconvenient situation. The owner must show why the property could not reasonably be occupied or put into the relevant use, and why the circumstance was not simply a choice to leave it empty.

The Conseil d’État applied that reasoning in decision no. 290366, 18 January 2008, available on Légifrance. The court described the relevant homes as those “pouvant être mis, sur simple décision du propriétaire, sur le marché immobilier locatif dans des conditions normales et durables d’habitation”. In English, the question is whether the property could be placed on the rental market by a straightforward owner decision in normal, durable living conditions. A British owner should therefore avoid relying only on an estate agent’s statement that the home was “not attractive”. The file should show the legal or physical obstacle that made ordinary letting impossible or objectively unreasonable.

Building works can be decisive, but the description must be precise. A property is not automatically outside the tax because it is being modernised, redecorated, or improved for a future sale. The evidence should identify the works required for safe and normal habitation: for example, unfinished water, electricity, sanitation, heating, structural, or access systems. Dated photographs should be matched to itemised quotations, invoices, planning or insurance documents, and the work schedule. If the home had one usable room but no functioning bathroom or safe electrical installation, say that clearly and explain the impact on the whole dwelling rather than presenting a vague renovation narrative.

In decision no. 499230, 15 July 2025, the Conseil d’État considered a property undergoing substantial renovation. The official decision on Légifrance says that the tax judge may require “tels que des devis portant sur les travaux à réaliser pour rendre le bien habitable”. That short passage means that quotations for the works needed to make the property habitable can be relevant evidence. The same decision records the constitutional limit that a property which could be made habitable only through important works falling necessarily on its holder should not be taxed as a voluntarily vacant habitable home. Luxury improvements, a new kitchen chosen for preference, or a higher-end finish should not be mixed with works required to restore basic habitability.

Decision no. 265562, 13 April 2005, also available on Légifrance, is useful for the broader principle that the administration must examine the cause of the vacancy. It distinguishes a home that cannot be offered because of an external circumstance from a home that is simply held back by its owner. A court order affecting possession, a serious disaster, an administrative safety order, a succession dispute that prevents lawful possession, or a documented inability to regain access may be relevant. Each example is fact-sensitive: a dispute that the owner could have resolved with ordinary steps is weaker than a legal prohibition or a third-party obstruction supported by contemporaneous documents.

Occupation also needs to be approached carefully. Under the future unified regime, a home occupied for more than 90 consecutive days in the relevant period is excluded. That does not mean that any 90 isolated nights will answer the test. Keep evidence of consecutive occupation: a tenancy agreement, check-in and check-out records, utility consumption, insurance declarations, travel records, bank payments, and correspondence with a managing agent. If family members used the home, explain who stayed, when, and under what arrangement. If it was rented for a long period but the owner’s online declaration still said “vacant”, correct the administrative record and attach the supporting document.

The legal landscape changes for assessments from 2027. Article 108 of Law no. 2026-103 of 19 February 2026 repeals the former TLV and THLV architecture and introduces the unified tax on vacant residential premises. The new Article 1406 bis of the CGI provides a one-year threshold in a commune with a marked housing imbalance and a two-year threshold elsewhere. It also excludes, among other cases, a home occupied for more than 90 consecutive days and a vacancy independent of the taxpayer’s will.

The new article keeps a 17% first-year rate and a 34% rate from the second year in the more pressured communes, while permitting higher local rates within statutory ceilings. Outside those communes, a local authority can institute the tax and set a rate within the new ceiling. This is why a 2027 notice should not simply be challenged by copying a 2026 letter. The municipality, threshold, local deliberation, statutory base, and period counted must be checked under the new article.

The reform also makes the occupation declaration more important. Article 1418 of the CGI, as amended for 2027, requires owners to declare the nature of occupation and related information before 1 July each year when a change has occurred. It says that “En cas de vacance du local, le motif de celle-ci est précisé”: where the premises are vacant, the reason for the vacancy must be specified. For 2027 assessments, the text also provides that the duration of vacancy before 1 January 2027 is taken into account. A British owner should therefore preserve evidence now, rather than waiting for the first unified notice.

In practical terms, separate three questions. First, was the property vacant for the statutory period? Secondly, was it capable of normal habitation or letting? Thirdly, if it was empty, was that the result of a voluntary decision or an external, documented obstacle? The answer to one question does not automatically answer the other two. A property can be empty but uninhabitable; it can be habitable but subject to a court order; or it can be available but used by family for a period that must be proved. Your claim should follow that sequence.

II. How can a British owner challenge the bill and prove an exemption?

A. Which documents and calculations should you file?

Begin with a one-page chronology. State the property address, cadastral reference if shown, ownership or usufruct position, dates of purchase or inheritance, the period of occupation, the date any tenant left, the start of works, and the date the property was first capable of normal use. Add the tax year and the date on the notice. A chronology prevents a common error: sending a document from 2025 to prove the condition on 1 January 2023, or relying on a quotation issued after the tax period without explaining why it describes an earlier defect.

Next, classify the evidence according to the ground you are relying on. Do not send a random bundle of photographs and assume that the tax office will construct the legal argument for you. The French tax administration’s current official guidance on a disputed TLV or THLV specifically refers to a lease, works quotations, and documents showing that the home was occupied or vacant on 1 January. Those examples are not exhaustive, but they show the type of factual proof expected.

If the home was occupied, file the tenancy agreement or written occupation arrangement, rent or service-charge payments, check-in and check-out evidence, utility bills or meter records, insurance correspondence, and the managing agent’s statement. A British owner who stayed in the property should identify the dates of consecutive use and retain travel or booking records where they help. Do not present a council-tax bill from the UK as proof that the French home was occupied. It proves a different fact in a different country.

If the home was uninhabitable, the strongest file normally combines several layers:

• dated photographs showing the condition on or close to the relevant 1 January;
• an independent report from an architect, surveyor, building professional, insurer, or public authority where available;
• itemised quotations identifying the defective systems and the work necessary to make the dwelling usable;
• invoices, payment records, permits, contractor correspondence, and a work timetable; and
• a short explanation linking each defect to ordinary habitation, rather than to a preferred luxury finish.

The distinction matters under decision no. 499230. A quote for replacing a non-functioning electrical installation or installing essential sanitation addresses habitability. A quote for a swimming pool, a premium kitchen, or an extension may show expenditure but not that the home could not be occupied or let in a normal condition. If the works were phased, identify which phase affected the legal use of the entire home and which phase was merely an improvement.

If the argument is that the market prevented a normal letting, document the steps taken rather than making a general statement that “nobody wanted the property”. Include a letting mandate, advertisements, dates of publication, proposed rent, viewing records, written refusals, evidence of a serious defect, and any independent rental assessment. Decision no. 290366 focuses on whether the home could be put on the rental market by a straightforward owner decision in normal and durable conditions. A price deliberately set far above comparable properties may weaken the argument. A documented safety problem, legal restriction, or market inability supported by professional evidence is different.

If the vacancy followed a succession or dispute, show the legal obstacle. A death certificate alone does not prove that a property could not be occupied or let. Add the will or notarial correspondence where relevant, the identity of the persons entitled to act, any court or insurance correspondence, an inventory, a possession dispute, or an order restricting access. If several heirs had to agree and the property could not lawfully be let without that agreement, explain what steps were taken and why the delay was not simply passive inaction.

Then check the calculation. Under the former TLV structure, the base is the cadastral rental value under Article 1409, not the purchase price and not necessarily the market rent. For illustration only, if the relevant statutory base were €8,000, a 17% first-year rate would produce €1,360 before any applicable additions, while a 34% second-year rate would produce €2,720. That example does not predict the amount on your notice. The notice, local rules, year, and property record control. For the 2027 regime, check the new Article 1406 bis rate and whether the commune has adopted a permitted local increase.

Verify the person named on the notice. A British owner may hold the property jointly, through a usufruct and bare-ownership split, after a death, or through a transfer that has not yet been fully reflected in the land and tax records. If the notice names a former owner, attach the deed or completion evidence and ask the tax office to correct the liable person. If the home was sold during the relevant period, do not assume that the sale date alone resolves a vacancy charge: the statutory holder and the period of vacancy must be reconstructed.

Update the property occupation declaration as well. For the 2027 regime, Article 1418 requires information about the type of occupation, dates, occupants, and, when there is vacancy, its reason. Use the “Biens immobiliers” section of the French tax account where available. A correction is not a substitute for a formal claim, but an unchanged record can make an otherwise strong evidence file look inconsistent. Keep a screenshot or confirmation of the update and note the date on the chronology.

For a related issue, where a French property is genuinely uninhabitable and the question concerns relief connected with ordinary taxe foncière, you can also review this guide to French property-tax relief for an uninhabitable rental property. It is not the same tax as TLV or THLV. The link is useful because a single building can generate several distinct French tax questions, each with its own legal test and time limit.

Keep a parallel UK file without allowing it to obscure the French issue. The GOV.UK guidance on UK income while living abroad explains that UK income can remain taxable in the UK and that the country of residence may also tax it, with treaty relief considered where applicable. That may matter for rent, pension income, or a later disposal. It does not prove that a French home was occupied and it does not replace evidence about French dates. Use it to coordinate advice, not to answer the vacancy question.

B. What is the deadline, and what happens after a refusal?

A challenge should begin with a formal French tax claim, called a réclamation. The service normally involved is the service des impôts des particuliers (SIP), the local personal-tax office. The official route is the secure messaging service in the owner’s French tax account: select a claim or contestation and identify the vacant-home tax. A paper letter can also be sent to the competent office shown in the notice. Use the address for the property or assessment, not an office selected merely because it is near your home in the United Kingdom.

The legal precondition is important. Article R*190-1 of the French Tax Procedures Book states: “Le contribuable qui désire contester tout ou partie d’un impôt qui le concerne doit d’abord adresser une réclamation au service territorial”. In English, the taxpayer who wants to dispute all or part of a tax must first submit a claim to the competent territorial service. A court application made before that administrative step can be rejected even when the underlying factual argument might have been serious.

Write the claim so that the tax office can identify the exact assessment. Give the taxpayer reference, tax year, property address, notice number, amount disputed, and the result requested: full discharge, partial discharge, correction of the liable person, or correction of the vacancy period. Then state the factual ground in one sentence, followed by the chronology and evidence. For example, the property was not habitable on 1 January because the electricity and sanitation systems were incomplete; the attached report, photographs, quotations, and contractor records establish that condition; and the vacancy was therefore not a voluntary choice to withhold a habitable home from the market.

Attach a numbered schedule. Each item should have a date and a short explanation of what it proves. If a document is in English, identify it in English and add a concise French description where that will help the tax office. Do not alter an original invoice, quotation, certificate, or tenancy record. If a translation is needed, preserve the original and identify who translated it. The point is traceability: the office should be able to move from the assertion in the claim to the page, date, and property concerned.

Respect the ordinary claim period. Article R*196-2 of the Tax Procedures Book, in the version in force from 30 July 2026, provides that claims concerning local direct taxes and related taxes must be filed by 31 December of the year following the relevant event, including the year in which the tax roll was put into collection or the notice was issued. Its wording begins: “Pour être recevables, les réclamations relatives aux impôts directs locaux et aux taxes annexes doivent être présentées à l’administration des impôts au plus tard le 31 décembre de l’année suivant”. As an example, a notice put into collection in 2026 would ordinarily lead to a 31 December 2027 deadline under that provision. Check the exact nature of the charge and any special rule before relying on the example.

Do not wait until the deadline to assemble the file. Send the claim through the secure channel, save the transmission receipt, download the message and attachments, and keep the notice. If using post, use a method that proves delivery and retain the complete copy. The administration may ask for additional evidence. Reply within the requested period and preserve a record of what was sent.

A claim does not automatically stop payment. The current guidance from impots.gouv.fr expressly warns that a claim does not suspend the tax and says that the taxpayer can request a sursis de paiement, meaning a deferral or suspension request, at the same time. State the amount contested and make the request expressly; do not assume that merely writing “I dispute this” has the same effect. The administration’s guidance also warns that if the claim is rejected and the tax remains unpaid, a 10% late-payment increase may apply. Obtain advice on the financial risk before refusing payment.

The response may grant a full discharge, a partial reduction, a correction, or a refusal. Read the reasoning rather than treating “refused” as the end of the case. A refusal based on an alleged lack of evidence may be answered with a focused supplement. A refusal based on the wrong year, wrong taxpayer, or wrong legal regime requires a different response. If the office says that the property was habitable, identify the document or observation on which that conclusion rests and answer it directly.

Decision no. 513256, 29 June 2026, is a recent warning about procedure. The Conseil d’État held that TLV under Article 232 was not a local tax for the jurisdictional rule at issue and noted that a claim for a 2017 assessment was manifestly inadmissible because the taxpayer had not first made the administrative claim required by Article R*190-1. The official text is on Légifrance. The decision records that the tax “ne saurait être regardé comme un impôt local” and, separately, that the required prior claim had not been made. The lesson is narrow but practical: identify the legal route for the tax you actually received, and prove that the prior claim was filed before asking a court to intervene.

If the tax office maintains its position, the next step depends on the notice, the year, the tax classification, and the relief sought. A judicial review is not a second opportunity to submit an unstructured bundle. The court will examine the administrative record, the legal test, the evidence, and the admissibility of the proceedings. A French administrative-tax lawyer can assess whether the refusal should be challenged, whether a new claim is possible for another year, and whether a payment-suspension request is appropriate. The fact that the owner lives in Britain does not prevent a French claim, but it makes reliable service addresses, powers of attorney, and a complete digital file especially valuable.

The 2027 transition should be handled separately from an old notice. Confirm whether the notice concerns 2026 under Article 232 or Article 1407 bis, or an assessment from 2027 under Article 1406 bis. For 2027, check the municipality’s classification, local deliberation, the one-year or two-year period, the 90-day occupation exclusion, and the reason recorded in the occupation declaration. The law takes account of vacancy before 1 January 2027, so a file created after the reform begins cannot safely ignore the earlier condition of the dwelling.

A concise claim normally follows this order:

1. identify the notice, property, tax year, taxpayer, and amount;
2. state whether you seek full or partial discharge and the legal ground;
3. give the dated chronology ending on the relevant 1 January;
4. match each factual statement to an indexed document;
5. request correction of the property occupation record where necessary;
6. request a payment deferral or suspension if payment is disputed; and
7. ask for a written decision and keep proof of delivery.

This format helps prevent the most damaging practical error: a British owner may have a persuasive story about renovation, a tenant leaving, or a succession, but the story is not connected to the statutory date or the formal remedy. A strong file answers the tax office’s questions in the order in which the law asks them: which tax, which property, which period, which condition, which cause, which evidence, and which remedy.

Conclusion

A French vacant-home tax is not cancelled merely because the owner is British, lives in the United Kingdom, pays UK council tax, or uses the property as a holiday home. For a 2026 assessment, establish whether the notice concerns TLV or THLV, verify the commune and the vacancy period, and examine whether the dwelling was habitable and voluntarily left empty. For 2027, prepare for the unified regime under Article 1406 bis and preserve evidence of the property’s condition before 1 January 2027.

The most useful response is early, dated, and specific. A tenancy record proves occupation; photographs and itemised quotations can address habitability; court or administrative documents can explain an external obstacle; and a market file must demonstrate more than a disappointing letting result. Submit the réclamation to the competent tax office before the applicable deadline, request a sursis de paiement if appropriate, and keep proof that the prior administrative step was completed.
