Owning a home in France after Brexit creates two separate questions that are often placed in the same tax file: what is payable because you own the property, and what is payable because you have its use as a home. The first question usually concerns taxe foncière, the annual French property tax on built property. The second may concern taxe d’habitation sur les résidences secondaires, or tax on a furnished second home, and the occupancy declaration held in the French tax administration’s “Biens immobiliers” service.
A British owner can therefore receive a bill that looks wrong for several different reasons: the wrong person is shown as having the property’s use on 1 January, a former tenant or occupier has not been removed, a holiday home is recorded as a main residence, a genuinely uninhabitable property is treated as available, or the taxable property description is no longer accurate. Brexit does not itself create an exemption from French local taxes, and the UK–France tax treaty does not turn a French local property charge into a UK-only liability. The remedy depends on identifying the tax, the relevant date and the precise error before sending a claim.
This guide is for a British owner dealing with a French home, not for the purchase process. It explains the distinction between the charges, how to correct an occupancy record, how to assemble proof and how to challenge the notice without losing the option of asking for payment to be deferred.
I. What French property tax does a UK owner actually owe after Brexit?
A. Which tax follows the property, the owner and the 1 January position?
The starting point is taxe foncière sur les propriétés bâties, usually shortened to taxe foncière. 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 charge is established each year on built properties situated in France, subject to statutory exemptions. The relevant official text is Article 1380 of the CGI.
This is a French local property tax. It is not a tax reserved for French nationals, French residents or people who bought the home through a particular structure. A British citizen living in the United Kingdom can still be liable as owner of a French house or apartment. The practical questions are the ownership position, the property’s taxable characteristics and any statutory relief. The fact that a British owner pays UK tax, files a UK return or visits France only occasionally does not, by itself, cancel taxe foncière.
The decisive annual rule is Article 1415 of the CGI: “sont établies pour l’année entière d’après les faits existants au 1er janvier de l’année de l’imposition”. The official provision is Article 1415 of the CGI. The meaning is important when a property changes hands, a tenancy ends, an owner moves to another country or an apartment becomes unusable. The administration looks at the legal and factual position on 1 January for that tax year; a later change may affect a later year or a specific relief, but does not automatically rewrite the whole annual charge.
For taxe foncière, the taxpayer is normally the person with the ownership right on the relevant date. Usufruct, bare ownership, a company holding the property and a change completed around the New Year can produce different results. This is why a bank transfer, a notary completion date or an estate document may matter more than a general statement that the property “belongs to the family”. A British executor should also separate the deceased’s liability from the administration of the estate and confirm which person or entity appeared in the French tax record.
The amount is not calculated simply from the purchase price. The legal assessment uses the property’s cadastral rental value, known in French as valeur locative cadastrale, and local rates. Article 1495 provides that each property or portion is assessed according to its consistency, use, location and condition. Read the wording in Article 1495 of the CGI. A new extension, a conversion of a garage, a change from residential to another use, a missing dependency or an incorrect area can therefore be a valuation issue even when the taxpayer’s identity is correct.
Article 1517 also requires the administration to take account of certain changes in consistency, use, physical condition or the surrounding environment. Its official wording is available at Article 1517 of the CGI. A taxpayer challenging a notice should say whether the dispute concerns the person liable, the property description, the cadastral basis, an exemption or a calculation. “The bill is too high” is a weak claim; “the 2026 notice treats a demolished independent outbuilding as part of the taxable dwelling, although the outbuilding was removed before 1 January 2026” identifies an issue the tax office can investigate.
The Conseil d’État has repeatedly required care with these factual elements. In its decision of 19 July 2016, no. 373090, it explained that works can alter the taxable basis through the mechanism in Article 1517 and referred to the owner’s notification duties under Article 1406. The decision is available on Légifrance, CE, 19 July 2016, no. 373090. In another decision, CE, 27 March 2015, no. 374460, the court dealt with the method used for the surface area and the annual facts relevant to local taxation; see Légifrance, CE, 27 March 2015, no. 374460. These decisions do not mean that every measurement disagreement wins. They show why the evidence must target the taxable characteristic actually used.
A limited vacancy relief exists, but it is frequently misunderstood by British owners of second homes. Under Article 1389 of the CGI, a taxpayer may seek a reduction of taxe foncière when a house normally intended for letting is vacant. The text requires, among other conditions, a vacancy lasting at least three months and a cause independent of the taxpayer. See Article 1389 of the CGI. A furnished holiday home that the owner simply leaves unused is not automatically a property “normally intended for letting”. Evidence of a genuine letting business, the dates of availability, advertising, a tenancy ending without the owner’s choice and the period of vacancy may all be relevant.
B. Why the occupancy declaration can trigger the wrong bill without changing ownership?
The second charge is different. Article 1407 of the CGI concerns the tax on furnished premises used as a residence other than a main residence. It says that the tax is due for “tous les locaux meublés conformément à leur destination d’habitation autre qu’à titre principal”. Read Article 1407 of the CGI. In everyday English, this is often the tax on a furnished second home, although the legal analysis depends on the facts and on the premises’ status.
Article 1408 adds a rule about use: “La taxe est établie au nom des personnes qui ont, à quelque titre que ce soit, la disposition ou la jouissance des locaux imposables.” The official section, including the current wording and its application, is at Article 1408 of the CGI. A person who has the right to use the premises can therefore matter even where another person owns the building. This is why a former tenant, an usufructuary, an occupier with a right of use or a family arrangement can change the analysis of taxe d’habitation without changing the land register or the ownership deed.
The French tax administration’s “Gérer mes biens immobiliers” service asks owners to declare the nature of occupation. The legal foundation is Article 1418 of the CGI, which says that owners of residential premises must declare information about “la nature de l’occupation de ces locaux”. Consult Article 1418 of the CGI. The record can distinguish a main residence, a secondary residence, rented accommodation, free accommodation and a vacant property, and it can ask for the identity of the occupier or tenant and the reasons for vacancy.
This declaration is not a second ownership deed and it is not a substitute for a complaint against a taxe foncière notice. Correcting it may prevent a future second-home or vacancy-related assessment, but it does not automatically recalculate the cadastral basis used for taxe foncière. If both records are wrong, make two linked but distinct requests: one to correct the occupancy information and one to challenge the tax notice on the legal ground that applies to that notice.
The current timetable also matters. For changes in the previous reporting period, the administration’s 2026 instructions required owners to update the information by 30 June 2026, or before 1 July. A British owner who missed that date should still correct the record as soon as possible; a late correction is better evidence of the true position than leaving an inaccurate declaration in place. It does not, however, make a claim automatically successful. Explain the date of the change and ask the office to state which tax years and taxes have been affected.
There is a further legal transition to handle carefully. The wording of Article 1418 has been amended for later local-tax administration, including more detailed information about the characteristics of the premises and vacancy. Do not use a new 2027 rule to assert that a 2026 tax notice was unlawful. Identify the tax year on the notice, the version of the law applicable to that year and the factual information held at 1 January.
Recent case law illustrates the importance of evidence rather than labels. In CE, 17 April 2026, no. 504694, the Conseil d’État considered who had effective enjoyment of premises and criticised a decision that failed to address the absence of returned keys and the steps taken by the person who claimed not to occupy the property. The official decision is Légifrance, CE, 17 April 2026, no. 504694. The lesson for a British owner is practical: a statement that “nobody lived there” should be supported by the end of the lease, key-return evidence, utility readings, insurance, photographs and correspondence about access.
In CE, 7 July 2026, no. 506653, the court stated that the address shown on an income-tax return is one possible piece of evidence but cannot automatically be presumed to be the taxpayer’s main residence for housing-tax purposes. Read the exact decision at Légifrance, CE, 7 July 2026, no. 506653. That is especially useful for a British taxpayer whose UK correspondence address, French mailing address and actual use of a French home do not tell the same story.
The UK–France Double Taxation Convention is relevant to income, pensions, gains and residence questions, but it should not be presented as a blanket exemption from French local property taxation. The UK government’s treaty text is available at GOV.UK, the UK–France Double Taxation Convention. A British owner should first identify the French local tax and then test its statutory rules; treaty language about another category of income does not answer an Article 1380 or Article 1407 dispute.
II. How can a British owner correct the declaration and challenge the bill?
A. What evidence and online steps should be used before the complaint deadline?
Begin with a one-page chronology. Write down who owned the property on 1 January of the tax year, who had the right to occupy it, whether it was furnished, whether it was rented or available for rent, when any tenant left, when keys were returned, what works affected the building and when each document was created. Then separate the documents into three files: ownership and legal rights; occupation and actual use; property condition and valuation. This prevents an occupancy argument from being buried in a long narrative about the purchase.
For an incorrect occupancy declaration, obtain a screenshot or PDF of the entry in “Biens immobiliers”, including the address, declared status, tenant or occupier details and date shown. Save the original before editing it. Explain precisely what must change: “secondary residence” to “vacant”, “former tenant” to “no occupier”, “tenant A” to “tenant B”, or a wrong date of occupation. If the system allows an online correction, make the correction and keep the confirmation. If the system does not allow it, send a message through the secure tax account and attach a concise statement.
The evidence should match the disputed proposition. If the issue is that the property was a main residence, use proof of habitual occupation: utility consumption, insurance, local registrations, correspondence, school or work records where relevant, and a chronology of travel. If the issue is that the property was a genuine secondary home, show where the owner’s main home was and how the French premises were used. If the issue is an ended tenancy, use the lease, notice, inventory, key-return record and utility readings. If the issue is vacancy caused by serious damage, use contractor reports, photographs, insurance correspondence and dates showing why the property could not be occupied.
For taxe foncière, request the notice and the underlying explanation instead of assuming the occupancy record is the source of the amount. Ask for the relevant cadastral description and the elements used to calculate the basis. Article 1406 requires notification of a new construction or a change in consistency or use within 90 days. The official text is Article 1406 of the CGI. If the dispute concerns an extension, a converted room, a demolished structure or a change of use, say when the event occurred and whether a declaration was made.
A useful evidence table looks like this:
| Problem | Evidence to attach | Request to make |
|---|---|---|
| Wrong person shown as occupier | Lease, termination, key return, identity and dates | Correct the occupancy record and cancel the assessment against the wrong user |
| French home recorded as a main residence | Main-home evidence, utility use, insurance and residence chronology | Reclassify the premises and review any second-home charge |
| Uninhabitable or genuinely vacant dwelling | Expert or contractor report, photographs, insurance and vacancy dates | Review the local tax and, where conditions are met, request the relevant relief |
| Wrong surface or property description | Plans, completion documents, photographs and measurements | Correct the cadastral characteristics and recalculate the basis |
| Ownership wrong on 1 January | Notarial deed, estate document, usufruct or bare-ownership instrument | Identify the legally liable taxpayer for the relevant year |
Keep the submission readable. Put the tax year, notice number, property address and requested result at the top. Then state the facts in date order, identify the legal ground, list the attachments and ask for a written decision. Use English explanations for the British reader’s own file, but submit the operative request in French or with a reliable French translation if the tax office requires it. Explain French terms at first use: réclamation means a formal tax claim, dégrèvement means a reduction or cancellation of an assessment, and sursis de paiement means a request to defer the disputed payment.
The formal complaint rules require more than a casual message. Article R*197-3 of the Book of Tax Procedures requires the claim to identify the tax, state the grounds and conclusion and include a copy of the notice. See the official text at Article R*197-3 of the LPF. A secure message can start the dialogue, but where the assessment is disputed, label the message clearly as a réclamation contentieuse and retain proof of sending.
The normal local-tax claim deadline is not simply “three months after the bill”. Article R*196-2 of the LPF sets the applicable time rules and the current official text is at Article R*196-2 of the LPF. For many local taxes, the claim can be made by 31 December of the year following the year in which the assessment was issued. Thus a 2026 taxe foncière or 2026 second-home tax will commonly require action no later than 31 December 2027, subject to the specific event and notice rules. A 2025 taxe foncière notice is generally within the 31 December 2026 period. Check the notice and the tax office’s guidance rather than waiting for the last week.
Service-Public confirms the practical distinction: a complaint about taxe foncière does not, by itself, suspend payment, while the taxpayer may ask for a payment suspension. Its 2026 guidance on disputing a property-tax notice is available at Service-Public, challenging a taxe foncière notice. If the taxpayer does nothing while the bill remains payable, late-payment consequences can arise even where the claim is later examined.
B. How do you request a reduction, payment suspension and judicial review?
Ask for the result in layers. First request correction of the factual record. Secondly request the dégrèvement or recalculation for the affected tax year. Thirdly, if immediate payment would create difficulty and the basis or amount is disputed, make an express request for sursis de paiement. Do not phrase it as “I refuse to pay”. State the amount disputed, the amount accepted if any, the legal ground and the evidence supplied.
Article L277 of the LPF provides the statutory route for a taxpayer who disputes the basis or amount of tax and asks to defer payment. The text states that the taxpayer may expressly request a suspension of payment and explains the consequences for enforceability while the dispute is pending. Read Article L277 of the LPF. The administration may require guarantees above the statutory threshold. A British owner should therefore seek written confirmation of the amount covered and whether a guarantee is requested.
Send the claim to the service named on the notice, normally through the secure messaging system for an online taxpayer or by the indicated postal route. A separate property can have a different tax office from the owner’s UK address. Keep the electronic acknowledgement, postal proof, the full notice, every attachment and a copy of the exact message. If the administration asks for further information, answer the question asked and repeat the remedy sought. A second, clearer submission should not contradict the first chronology.
The administration must examine the claim. Article R*198-10 of the LPF provides for a decision within six months, with a possible additional period in the conditions set by the text, and requires reasons for a rejection. Consult Article R*198-10 of the LPF. If there is no answer, silence is not a reliable reason to assume that the bill disappeared. Monitor the account and the payment position, and obtain advice about the next procedural step.
A refusal should be analysed, not merely answered with more documents. Common reasons include: the evidence concerns a different year; the wrong tax was challenged; the taxpayer did not prove that the premises were unavailable; the requested vacancy relief applies only to a property normally intended for letting; the person who filed the claim was not the liable taxpayer; or the complaint did not meet the formal requirements. Identify which reason appears in the decision and answer that reason with the missing document or the correct legal argument.
The Conseil d’État decision of 11 December 2009, no. 309240, is a useful reminder that a valuation comparison must account for differences between properties and cannot be replaced by a generic complaint that a neighbour pays less. The official decision is at Légifrance, CE, 11 December 2009, no. 309240. Ask for the valuation elements, explain the material difference and provide objective evidence. A lower bill for a nearby property is a lead for investigation, not proof of unlawful assessment.
If the dispute concerns use of the premises, CE, 17 April 2026, no. 504694, can help frame the evidence: access, keys, an effective right of enjoyment and the conduct of the parties can be more probative than a label on a form. If it concerns the owner’s main residence, CE, 7 July 2026, no. 506653, supports a factual approach rather than an automatic assumption based on the address in an income-tax return. Neither case creates a general exemption for British owners; each shows how the court tests the relevant facts.
A court challenge should be considered only after identifying the administrative decision and the competent route. The court will generally expect the claimant to show the notice, the formal complaint, the response or the expiry of the relevant period, the legal ground and the evidence. A file containing only a tax-account screenshot will rarely answer a dispute about ownership, a lease, a valuation or the condition of the building. Organise exhibits chronologically and refer to each exhibit in the written argument.
There are practical mistakes to avoid. Do not edit the occupancy declaration and assume the old tax notice has been cancelled. Do not use a UK council-tax record as if it were a French cadastral record. Do not attach an estate document without explaining the date on which ownership or usufruct changed. Do not claim vacancy relief for a private holiday property without evidence that the statutory letting conditions are met. Do not send a late complaint without explaining the legal event that may extend or reopen the time limit. Do not omit the request for payment suspension when the immediate payment risk is the reason for acting.
Finally, treat the UK side as context rather than a substitute for the French procedure. GOV.UK’s guidance for people living in France warns that assets and income held outside France may require French reporting, but a UK filing does not correct a French local-tax record. The relevant guidance is GOV.UK, living in France. A British owner who also rents the property, receives a pension or sells it will need separate advice on those issues. The local-tax claim should remain focused on the tax year, the premises and the precise correction sought.
Conclusion
For a British owner, a wrong French property-tax bill is usually solved by separating three questions: who was legally liable on 1 January, who had the property’s use and what physical or cadastral facts determined the basis. Taxe foncière follows the built property and the statutory ownership rules; second-home tax follows the legal and factual use of furnished premises; the occupancy declaration is an administrative record that may affect the latter but does not replace a formal challenge to the former. For the related calculation and challenge issues, see our guide to challenging French capital-gains tax on a second home.
Preserve the original declaration, correct the record with a dated chronology, file a formal réclamation with the notice and targeted evidence, and request a dégrèvement or recalculation for the correct tax year. If payment is disputed, ask expressly for sursis de paiement rather than assuming the complaint suspends collection. A focused file based on the 1 January position, the actual use, the property’s condition and the statutory deadline gives the French tax office—and, if necessary, the court—a clear issue to decide.
