After selling a French home, a British owner can receive a full taxe foncière bill even though the keys, the benefit of the property and the risk of ownership have passed to the buyer. Taxe foncière is the French property tax charged to the owner or, in some cases, to a usufructuary. The result often looks surprising: the seller may have owned the property for only part of the year, yet the French tax authority does not automatically split the annual assessment between the parties.

Two different questions must be kept separate. First, who is legally liable to the French tax authority for the relevant year? Secondly, does the signed sale deed give the seller a contractual right to obtain a time-apportioned reimbursement from the buyer? Brexit and British nationality do not remove that distinction. The first question is governed mainly by the facts existing on 1 January; the second depends on the wording of the deed and the evidence of payment. This article explains the position for a completed sale of a French home. It does not replace advice on the purchase process, and it does not turn a private reimbursement clause into a tax ruling.

I. Who pays French taxe foncière after a sale?

A. Is the seller still liable if the house was sold during the year?

The starting point is the French tax year, not the date on which the sale completed. The relevant tax is usually the taxe foncière sur les propriétés bâties, commonly abbreviated as TFPB, meaning the property tax on built property. It is assessed against the person who has the legally relevant ownership position at the beginning of the year. A British owner who sells a house in April, June or November should therefore expect the annual bill to remain connected to the position on 1 January, subject to the facts of the transfer and any statutory relief.

Article 1400 of the French General Tax Code states: “toute propriété, bâtie ou non bâtie, doit être imposée au nom du propriétaire actuel”. In English, the property is assessed in the name of the current owner. The provision is not a rule that recalculates the tax every time a property changes hands. It identifies the person in whose name the property is imposed, subject to the statutory exceptions referred to by the article.

Article 1415 of the same Code supplies the annual rule: the local taxes are “établies pour l’année entière d’après les faits existants au 1er janvier”. That short sentence is the reason a sale during the year does not, by itself, create two tax notices or a legally enforceable tax split. If the seller was the taxable owner on 1 January 2026, the seller remains the person the Direction générale des finances publiques (DGFiP, the French public finance administration) will normally pursue for the 2026 assessment.

The practical consequences are straightforward:

• If the sale transferred ownership on 15 April 2026, the seller will normally remain the taxpayer for the whole 2026 taxe foncière. The buyer’s legal liability will normally begin with the position on 1 January 2027, not with the April date.
• If the sale completed on 15 December 2026, the same annual principle still applies. A late-year completion does not automatically generate a twelve-day tax assessment for the seller and a separate assessment for the buyer.
• If the parties signed an agreement to divide the annual amount, that agreement operates between them. It does not instruct the DGFiP to issue a new assessment in the buyer’s name for the buyer’s part.

The precise transfer date still matters for the contract between seller and buyer. The deed may state when ownership, possession, benefits and charges pass. It may also contain a separate clause for taxes. Those contractual dates should not be confused with the tax authority’s 1 January test. A British seller should read the authentic deed, the notary’s completion statement and the tax notice together rather than relying on the date the estate agent advertised the sale or the date the keys were handed over.

The rule is not changed merely because the seller lives in the United Kingdom, is a British citizen, or reports other income under the France–UK double taxation agreement. TFPB is a French local property tax attached to French property. The nationality of the owner does not create an exemption, and Brexit does not convert the charge into a UK council-tax calculation. A non-resident British owner can still be the person named on the French notice.

The tax base also explains why the notice is not normally divided after the sale. Article 1388 of the French General Tax Code says that the tax is “établie d’après la valeur locative cadastrale”, the cadastral rental value, after the statutory allowance. This is a valuation mechanism for the property and its situation; it is not a daily invoice for the period during which each owner occupied the home. A sale can be financially apportioned by contract without changing that underlying annual assessment.

There are, however, situations in which the seller should examine the notice itself rather than simply seeking the buyer’s contribution. The property may have been transferred before 1 January, the notice may concern the wrong address or a duplicated account, the cadastral description may be wrong, or a statutory reduction may have been omitted. An owner who rented the property may also need to examine whether an involuntary and sufficiently long vacancy qualifies for relief. The seller should not tell the buyer that a tax notice is “wrong” merely because it is for the whole year; that is often the normal consequence of Article 1415.

The official Service-Public explanation of taxe foncière confirms the practical rule: the person who owns or holds the relevant right on 1 January is generally liable, and a seller who disposes of the property during the year can ask the buyer for reimbursement only where the private agreement supports it. The same explanation distinguishes the tax debt from a private arrangement. That distinction is the foundation of any sensible response to a 2026 notice.

B. Can the sale deed make the buyer reimburse the seller?

Yes, often it can, but the right comes from the sale deed rather than from Article 1415. French conveyancing deeds frequently contain a prorata temporis clause. This means a time-apportioned share: the seller pays the annual bill to the tax authority, and the buyer reimburses the part corresponding to the period beginning on the contractual transfer date. The calculation is private. The DGFiP remains entitled to seek the whole tax from the legally liable person.

A clear clause can say that the buyer will bear or reimburse the proportion of the annual taxe foncière attributable to the period after completion. It may use a formula based on calendar days, months or the practice agreed in the deed. It may also state that the buyer’s share is calculated from the date of the acte authentique, the formal notarial deed, rather than from the date of an earlier promise. The actual words matter. A reference to “taxes and charges from today” may need to be read with the rest of the deed, while an express promise to reimburse “the prorata of property tax” is much easier to prove.

Article 1103 of the Civil Code provides: “Les contrats légalement formés tiennent lieu de loi à ceux qui les ont faits.” A lawfully formed contract binds the parties as their law. Article 1193 adds: “Les contrats ne peuvent être modifiés ou révoqués que du consentement mutuel des parties, ou pour les causes que la loi autorise.” In practical terms, a buyer who signed a reimbursement clause cannot normally disregard it simply because the tax authority addressed the annual notice to the seller.

The wording must still be identified precisely. Look for the clause in the part of the deed dealing with taxes, charges, adjustments and the date of possession. Record whether it refers to:

• the taxe foncière itself, rather than all “taxes” in an undefined sense;
• the annual amount shown on the tax notice, including or excluding a separate waste-collection charge;
• the date on which the buyer takes ownership, possession or enjoyment;
• a calculation already made in the notary’s completion statement; and
• a mechanism for payment, such as a deduction from completion funds or a later transfer.

The taxe d’enlèvement des ordures ménagères (TEOM, the household-waste collection tax shown with some property-tax notices) deserves particular care. A deed may allocate it by reference to actual occupation or to the same prorata as the taxe foncière, but the clause should be checked rather than assumed. A seller should copy the relevant wording into a calculation letter and identify the exact line items. An unexplained demand for “half the taxes” is weaker than a demand tied to the deed and the official notice.

A decision of the Cour de cassation, Première chambre civile, 22 June 2017, no. 16-14.858, illustrates why the contractual wording matters. The deed in that dispute included the words “il remboursera au vendeur le prorata d’impôts foncier”. The official decision is available on Légifrance, Cour de cassation, no. 16-14.858. The case should not be reduced to a universal rule that every seller automatically recovers a share. Its useful lesson is narrower: where a deed contains an express allocation, the court must examine the clause, the transaction and the parties’ obligations rather than treating the tax notice as the entire contract.

The same distinction appears in a different setting in the decision of the Cour de cassation, Troisième chambre civile, 17 November 2016, no. 15-18.339. The decision refers to “la taxe foncière dont le paiement n’incombe pas légalement au preneur qui n’est pas le propriétaire des lieux”. The official text is at Légifrance, Cour de cassation, no. 15-18.339. A tenant may have to reimburse a landlord under a lease clause, but the tenant is not thereby transformed into the legal owner-taxpayer. The same analytical separation applies after a sale: an internal reimbursement obligation does not rewrite the public tax assessment.

For example, suppose the 2026 notice is €1,440 and the deed says that the buyer reimburses the period from 15 April to 31 December. If the parties use 261 calendar days out of 365, the indicative calculation is €1,440 × 261 ÷ 365, or approximately €1,030. The deed may use a different convention, particularly if it specifies whole months or a particular completion date. The seller should apply the agreed method, retain the arithmetic and avoid rounding until the final figure. The notary’s statement may already contain the answer.

French case law also recognises the importance of the 1 January position when a tax liability is being discussed in another legal context. In a decision of the Cour de cassation, Commercial Chamber, 28 March 2006, no. 03-13.822, the official record refers to the person liable for the tax for a year as the owner on 1 January. It is available at Légifrance, Cour de cassation, no. 03-13.822. That decision is not a substitute for reading the sale deed, but it reinforces the need to keep the public liability date separate from the private payment arrangement.

The notary is useful evidence but is not automatically the party who owes the seller money. At completion, a notary may have retained sums, prepared an adjustment, or recorded the buyer’s share in the statement of account. If the amount was calculated but not transferred, ask for the accounting record and the reason for the missing payment. If the deed contains no reimbursement clause, the notary’s customary practice alone may not create a new obligation for the buyer. If the notary made a professional accounting error, the seller should first make a written complaint and preserve the deed, statement and correspondence. The official Service-Public guidance on a dispute with a notary describes the staged route for a written complaint and, where appropriate, mediation or further proceedings.

The key answer to the title question is therefore conditional. A British owner can recover the buyer’s share if the signed deed, interpreted in context, creates that reimbursement obligation and the seller can prove the amount paid. The seller cannot demand a reimbursement solely because the property was sold mid-year. Nor can the seller ask the DGFiP to collect the buyer’s share as if the buyer had been the taxpayer on 1 January.

II. How can a British owner recover or challenge the amount?

A. When should you challenge the French tax authority?

A challenge to the DGFiP is appropriate when the assessment itself is wrong or a statutory right to relief has been overlooked. It is not the correct route for enforcing a private prorata clause against a buyer. The first task is to decide which of those two disputes exists. There can be both: a seller may have a defective notice and, separately, a contractual claim for the sum that was correctly paid.

The tax procedure is called a réclamation contentieuse, meaning a formal claim asking the tax administration to correct an assessment or grant a statutory reduction. Article L190 of the Book of Tax Procedures places claims seeking correction of the tax base, calculation or statutory entitlement within the contentious tax jurisdiction. The claim should identify the taxpayer, property, tax year, notice number, disputed amount and precise relief sought. A general email saying that the bill is unfair is less useful than a structured claim with documents.

Under Article R*190-1 of the Book of Tax Procedures, the taxpayer “doit d’abord adresser une réclamation au service territorial” responsible for the place of taxation. For a British owner abroad, the relevant service is generally the DGFiP office shown on the notice, often accessible through the secure messaging area of the French tax account or by the written method specified by the administration. Use the contact details on the actual notice. Keep proof of submission, attachments and the date sent.

The usual time limit for a local direct-tax claim is important. Article R*196-2 of the Book of Tax Procedures begins: “Pour être recevables, les réclamations relatives aux impôts directs locaux”. In the ordinary case, a claim relating to an assessment issued for a given year must be made by 31 December of the following year, subject to the rules and exceptions applicable to the notice and the form of error. For a 2026 taxe foncière notice, that ordinarily points to 31 December 2027. Do not wait for the buyer dispute to resolve before checking the administrative deadline, and do not assume that a complaint to the notary suspends it.

Possible administrative grounds include:

• The seller was not the legally relevant owner or right-holder on 1 January, and the deed and land-registration evidence demonstrate a different position.
• The notice relates to the wrong property, a duplicate account, an old address or a property that has been divided, demolished or materially changed.
• The cadastral rental value, classification, surface or other factual input used for the assessment is demonstrably wrong. Article 1388 is the starting point for understanding the cadastral basis.
• A statutory exemption or reduction has been omitted. For example, Article 1389 of the General Tax Code allows a reduction in cases of qualifying vacancy, using the words “dégrèvement de la taxe foncière en cas de vacance”. The vacancy must meet the legal conditions, including being involuntary and lasting for the required period; a property merely used less often is not automatically enough.
• The payment has been duplicated or a previous correction has not been reflected on the notice.

The evidence should be assembled before the claim is filed. Include the tax notice, the signed deed and its annexes, the notary’s completion statement, proof of the transfer date, the cadastral or property account details, photographs or invoices where a physical condition is relevant, and a clear table showing the amount disputed. If the argument concerns a wrong address, include the correspondence that prevented the seller from receiving the notice. If the argument concerns a qualifying vacancy, retain the letting mandate, advertisements, termination evidence, utility records and dates that show the legal period.

Paying the notice and challenging it are not always alternatives. A tax claim normally does not suspend collection. Article L277 of the Book of Tax Procedures permits a taxpayer who expressly requests it in the claim and satisfies the relevant conditions “à différer le paiement de la partie contestée”. This is a sursis de paiement, a deferral of the disputed payment, not an automatic pause. The administration may ask for guarantees above the applicable threshold and may continue to collect sums that are not properly covered. A seller who wants to avoid enforcement should make the request in the correct form rather than simply withholding payment.

The administration may grant a reduction, reject the claim, or remain silent. A refusal should be read with its reasoning and the appeal information. Under Article L199 of the Book of Tax Procedures, a dispute with the tax administration can, in the circumstances covered by the provision, be brought before the tribunal administratif, the administrative court. Article L199 states that the relevant claims “peuvent être portées devant le tribunal administratif”. The court does not decide who owes a private contractual prorata merely because the tax dispute is attached to the same property.

The decision of the Conseil d’État, 8th and 3rd chambers sitting together, 21 October 2020, no. 443327, is a useful procedural reminder. In the situation considered, the Conseil d’État addressed the absence of a response and the point at which a court challenge can be brought; the official decision is at Légifrance, Conseil d’État, no. 443327. It explains that, where the administration has not issued a properly notified express rejection, “aucun délai de recours contentieux ne peut courir” in the circumstances described by the decision. That does not mean that a taxpayer can ignore every procedural time limit. It means that the date and form of the administration’s decision must be checked carefully before calculating the court deadline.

For a British owner, language and distance create practical risks. A secure-message submission should be saved as a PDF or screenshot, French documents should be translated accurately where necessary, and the seller should identify the French tax year rather than refer vaguely to “this year”. The UK tax position should not be used as the main reason to cancel French property tax. If the issue is a French local assessment, the French notice, French code provisions and French administrative procedure are the evidence that matter.

B. When should you claim the prorata from the buyer or notary?

When the notice is correctly addressed to the seller and the dispute concerns the buyer’s agreed share, the claim is contractual. Start with the signed deed, not with a generic internet calculator. Identify the exact clause, the date it uses, the amount on the notice and the amount already paid. Then check whether the notary’s completion statement has already settled the adjustment. The claim should explain why the seller is the legal taxpayer but the buyer is contractually required to reimburse a specified proportion.

Article 1103 of the Civil Code supports enforcement of a clear promise. Article 1193 prevents one party from changing the agreed allocation unilaterally. If the buyer refuses to perform, Article 1217 of the Civil Code lists remedies for non-performance, including “demander réparation des conséquences de l’inexécution”. The available remedy depends on the clause, the proof of breach, the amount and the procedural route. The articles do not guarantee recovery where the deed is silent or ambiguous.

A first demand should be calm and documentary. Attach or quote the relevant clause, identify the tax notice and show the calculation in a small table:

• annual taxe foncière stated on the notice;
• any TEOM or other line included or excluded under the deed;
• contractual start date for the buyer’s share;
• contractual end date, normally 31 December of the tax year;
• number of days or months used and the agreed denominator; and
• amount paid by the seller and amount requested from the buyer.

Send the demand to the address and email specified in the deed or the notary’s file. Give a reasonable deadline for payment and provide bank details through a secure channel. If no payment follows, a French mise en demeure, meaning a formal demand to perform, can put the buyer on notice and preserve a clear record of the dispute. The letter should not say that the DGFiP has decided that the buyer owes the money. It should say that the buyer signed a clause allocating the private cost between the parties.

If the notary’s completion statement records a prorata deduction, ask the notary to explain the entries and the destination of the funds. A request for the accounting record is different from a demand that the notary personally pay the tax. If the buyer’s funds were held and the notary failed to carry out an express instruction, the seller may need to examine the notary’s professional obligations and the evidence of the instruction. Begin with a written complaint and obtain the notary’s response. The Service-Public dispute route linked above can help identify the next stage, but it does not remove the need to establish the buyer’s contractual debt.

If the buyer says, “I was not the owner when the tax was assessed,” that answer confuses public liability and private allocation. It may be correct that the buyer was not the taxpayer under Article 1415. It does not answer a clause promising reimbursement after completion. Conversely, if the deed says nothing about a prorata and the parties did not agree one separately, the seller cannot create that obligation simply by sending a calculation. The seller’s strongest case is usually a signed clause with a defined date and a notice that matches the property.

The court evidence should be organised chronologically: offer or preliminary agreement if relevant to interpretation, authentic deed, completion statement, transfer date, tax notice, proof of payment, calculation, demand and buyer’s response. Keep the original French wording. An English translation can be supplied for the British client, but the French deed controls. If the buyer disputes the arithmetic, show the formula used by the deed and explain any difference between the annual tax, TEOM and other charges. If the buyer disputes the clause, the court will need the whole deed, not an isolated sentence copied into an email.

A seller should also consider whether the proposed recovery is economically sensible. A modest claim may be resolved by the notary or a negotiated payment, while a larger claim may justify a formal letter and proceedings. Do not add unrelated claims about the sale price, defects or agency fees to a simple taxe foncière demand unless they are legally connected. A focused claim makes the contractual issue easier to verify and reduces the risk that a buyer treats the demand as an informal renegotiation of the sale.

The French property-tax dispute should also be kept separate from UK capital-gains reporting. The GOV.UK guidance on selling overseas property explains that a UK tax resident can have UK Capital Gains Tax obligations on an overseas property, while non-residence and temporary non-residence rules can affect the result. The France–UK treaty may coordinate taxing rights and relief, but it does not decide whether a buyer must reimburse a French local tax under a sale deed. Ask separate questions of the French property file and the UK tax return.

Before sending the final demand or filing an administrative claim, use this decision sequence:

1. Read the tax notice and establish the relevant year and property.
2. Check who held the legally relevant ownership position on 1 January.
3. Decide whether the complaint concerns a wrong assessment, a statutory reduction, a private prorata, or more than one of these.
4. Read the signed deed and notary statement for the exact reimbursement wording and transfer date.
5. Pay the tax or make a properly framed sursis de paiement request if a genuine assessment is being challenged.
6. Send a separate, evidenced contractual demand to the buyer or request the notary’s accounting explanation.
7. Diary both the tax-claim deadline and any deadline that may affect a civil recovery, taking advice on the facts rather than assuming that one letter stops every clock.

That sequence prevents two common mistakes. The first is refusing to pay the DGFiP because the buyer has not reimbursed the seller; the buyer’s breach does not automatically cancel the public tax debt. The second is asking the DGFiP to enforce a private deed clause; the tax administration can correct an assessment, but it is not the collection agent for a contractual prorata. The seller should run the two tracks separately, with consistent dates and figures.

For a British owner living outside France, the file should be ready in both languages and should identify a reliable address for notices. Keep the tax account messages, the registered delivery receipt, the deed in full and the notary’s ledger. If the property was held through an estate or a French société civile immobilière (SCI, a civil property-holding company), ownership and contractual wording may require a different analysis. The same 1 January principle remains a starting point, but the person named on the notice and the party who signed the sale deed must be verified rather than assumed.

Conclusion

A British owner who sells a French home during 2026 will normally remain liable to the DGFiP for the full annual taxe foncière if the owner held the relevant position on 1 January. That does not end the analysis. A clear clause in the signed sale deed may require the buyer to reimburse the period after completion, even though the buyer was not the public taxpayer for that year. The correct response is to separate the administrative track from the contractual track: challenge the DGFiP only where the assessment or statutory relief is wrong, and claim the prorata from the buyer or address the notary’s accounting where the deed supports it. Preserve the notice, deed, calculation and proof of payment, and act before the relevant procedural deadlines.
