Paid a full French property-tax bill after selling your home and now wondering whether the French tax office owes you money? The answer depends on a distinction that is easy to miss when you are dealing with a notary, a buyer and an administration in another country. Taxe foncière is the annual French property tax. The tax authority normally looks at who owned the property on 1 January, while the sale contract may privately divide the cost between seller and buyer. Those are two different questions.

A British owner may therefore have a valid claim, but not necessarily because the sale took place during the year. A refund from the French tax authority usually requires an error in the person assessed, the property, the calculation or a statutory relief. If the assessment is legally correct but the deed says that the buyer must bear the post-completion share, the route is contractual recovery from the buyer, not a tax refund. This guide explains how to separate those routes, assemble proof and protect the deadline for a formal French claim. It also distinguishes a routine sale from the rare situation in which a court retrospectively cancels or resolves the transfer of ownership.

The focus is the British individual who owns, has owned or has just sold a French property. It does not address the purchase process itself, French company structures or a UK Capital Gains Tax calculation. For the separate UK treatment of a disposal of overseas property, consult the relevant GOV.UK guidance on selling overseas property. The practical question here is narrower: after a French sale, was the taxe foncière correctly charged, and if not, how can the overpayment be recovered?

I. “French taxe foncière after selling: who is liable and can a British owner recover money?”

A. “Does the seller pay the full French property tax after a sale?”

The starting point is not nationality, residence or the date on which the sale proceeds reached your UK bank account. It is the French property-tax rules for the relevant 1 January. The taxe foncière sur les propriétés bâties is the tax on built property, such as a house or flat. Article 1380 of the French General Tax Code, the Code général des impôts or CGI, states that “La taxe foncière est établie annuellement sur les propriétés bâties sises en France”. That is a charge connected with the French property, not with the owner’s British passport.

Article 1400 of the CGI then provides that “toute propriété, bâtie ou non bâtie, doit être imposée au nom du propriétaire actuel”, subject to the provisions dealing with cadastral changes and changes in the tax debtor. Article 1415 adds the crucial annual rule: the taxes are “établies pour l’année entière d’après les faits existants au 1er janvier”. Read together, those provisions explain why the owner on 1 January is usually the person assessed for the whole tax year, even if the property is sold in March, June or November.

Suppose you owned a house in Brittany on 1 January 2026 and completed the sale on 30 September 2026. In the ordinary case, the French tax office will issue the 2026 avis de taxe foncière, meaning the tax notice, in your name. You remain the legal debtor for that assessment. Moving back to Manchester, becoming non-resident in France, or receiving the notice at a British address does not divide the public-law liability into nine months and three months.

The official tax administration explains the same position in its answer to the question of who pays when a property is bought or sold during the year: the owner on 1 January remains liable for the entire year. The impots.gouv.fr sale and purchase guidance also explains that the deed may contain a private arrangement for a proportionate contribution. Service-Public presents the rule in similar terms on its page about taxe foncière on built property.

That private arrangement is often called a prorata temporis clause, meaning a division according to time. It is common for a deed to say that the buyer reimburses the seller for the part of the annual bill corresponding to the period after completion. If the annual bill is €1,800 and completion took place on 30 September, a simple three-month calculation would be €450. That figure is a matter between the parties. It does not mean that the tax office should issue a €450 refund to the seller, and it does not change the identity of the public-law debtor.

This difference matters when a British owner sees a full bill after completion and assumes that the French administration has made a mistake. The bill may be entirely correct. The seller then has two possible tasks: pay the tax to avoid recovery action, and enforce the reimbursement clause against the buyer if the buyer does not pay. A request to the service des impôts des particuliers, or SIP, which is the local individual tax office, cannot usually turn a valid annual assessment into a time-apportioned assessment simply because the deed used a prorata calculation.

The contractual route starts with the exact wording of the acte authentique, the notarised deed of sale. Look for the paragraph dealing with taxes, charges and adjustments at completion. Some clauses use the latest available notice and provide an estimate; others require an adjustment when the current year’s notice is known. Some are drafted as a direct reimbursement obligation, while others merely record the parties’ intention. The distinction can affect whether a formal demand, interest or court proceedings are appropriate.

Do not overlook the difference between the property tax itself and other lines that can appear on the same notice. The taxe d’enlèvement des ordures ménagères, or TEOM, is a household-waste collection tax shown with the property-tax bill but governed by its own rules and contractual practice. A deed may refer to “taxes foncières” generally, or it may exclude particular charges. Compare the notice line by line with the clause instead of applying a percentage to the total automatically.

The calculation of the tax also needs to be understood before alleging an overpayment. Article 1388 of the CGI links the built-property tax to the valeur locative cadastrale, meaning the cadastral rental value, with the statutory allowance used to establish the taxable base. Local rates and additional taxes can then make the amount look very different from a previous year. A rise, even a substantial one, is not by itself evidence that the wrong person or wrong amount was assessed.

A sale before 1 January gives a different factual starting point. If you completed the sale on 20 December 2025 and were no longer the owner on 1 January 2026, the 2026 assessment should normally relate to the new owner, provided the ownership information has been properly transmitted and recorded. If an old owner still receives the notice, the issue is not a routine prorata dispute. It may be a cadastral or registration problem, and the documents must show exactly when the legal transfer occurred and whether it was published in the property records.

The same analysis applies if the property was transferred to a buyer who lives in France, the United Kingdom or another country. A British address can create practical problems with notices, direct debits and correspondence, but it does not create a special post-Brexit apportionment of the tax. Brexit may affect residence, reporting and the administration of a cross-border sale; it does not displace the French 1 January rule for a French property.

B. “When is a French property-tax bill genuinely wrong after completion?”

A genuine tax overpayment is more likely where the person assessed was not the legal debtor, the same property was assessed twice, the notice relates to a property already transferred before 1 January, the cadastral description is wrong, a taxable base contains a demonstrable error, or a statutory exemption or relief was omitted. It is also possible that a payment was duplicated even though the assessment was correct. Each situation needs its own proof and remedy.

The cadastral rules are central where the wrong owner appears on the notice. Article 1402 of the CGI says that “Les mutations cadastrales consécutives aux mutations de propriété sont faites à la diligence des propriétaires intéressés”. A mutation cadastrale is the administrative change to the cadastral record following a change of ownership. The same provision links the change to prior publication of the deed or judicial decision in the fichier immobilier, the French land-registration file.

Article 1403 sets out the risk created by a delay: “Tant que la mutation cadastrale n’a pas été faite, l’ancien propriétaire continue à être imposé au rôle”. The rôle is the official tax roll. This does not mean that a former owner has no remedy, but it means that the administrative record must be corrected through the proper chain of deed, publication and cadastral update. A letter saying that the keys were handed over is not always enough to prove the legal change relevant to the assessment.

Article 1404 deals with the situation in which a property-tax contribution was established in the name of someone other than the legal debtor. Its text provides that “le dégrèvement de cette cotisation est prononcé à condition que les obligations prévues à l’article 1402 aient été respectées”. A dégrèvement is a cancellation or reduction of an assessment, which can lead to repayment when money has already been paid. The condition is important: the tax office may require the ownership formalities to be completed before it corrects the charge.

The Conseil d’État has applied this sequence in a case involving a tax contribution issued to a person other than the legal debtor. In its decision of 19 November 2008, no. 285472, it held that “le dégrèvement ne peut être prononcé qu’après que les propriétaires intéressés ont fait procéder à la mutation cadastrale”. The official decision is available on Légifrance, Conseil d’État, 19 November 2008, no. 285472. The practical lesson is that a British seller should obtain the notarial deed, the publication evidence and the cadastral correction rather than relying only on the date printed on an email from the buyer.

That decision also warns against a common procedural assumption. A correction to the cadastral record does not automatically create a new claim period for every earlier assessment. If the owner’s own delay caused the record to remain unchanged, the administration or court may examine whether the legal deadline has expired. The question is not simply “has the record now been updated?” It is “what event legally supports the claim for this particular year, and was the claim presented within the applicable period?”

A routine sale should also be separated from a judicial cancellation or resolution of the transfer. In its Section decision of 26 July 1991, no. 51086, the Conseil d’État recognised the relevance of a judgment that had, “avec effet rétroactif l’annulation ou la résolution d’un acte portant transfert de propriété”. The official text is Légifrance, Conseil d’État, Section, 26 July 1991, no. 51086.

This is a narrow exception, not a general right to recalculate tax whenever a sale later becomes contentious. A final judicial decision may retrospectively alter the legal position for the relevant year. A disagreement about defects, delayed completion, a failed negotiation or an unpaid contractual reimbursement does not have the same effect. Before relying on the 1991 decision, identify the operative part of the judgment, its final status and the precise date from which the ownership transfer was cancelled or resolved.

There are other possible errors that do not turn on the sale date. A notice may concern a neighbouring parcel, an annex that was demolished, a duplicate account or an incorrect classification. A relief may have been requested but not applied. A rental property may have been vacant or uninhabitable, but the statutory conditions for any relief must be tested separately; the existence of repair work alone does not guarantee a reduction. Our guide to relief for an uninhabitable French rental property addresses that different factual route.

Payment errors are another category. Check whether a French bank direct debit was taken twice, whether a payment made from a UK account was allocated to the correct tax reference, and whether a co-owner or buyer also paid the same notice. A bank statement can prove that money left your account, but it does not alone prove that the assessment was unlawful. The claim must identify the tax notice, the legal error and the amount sought.

Finally, distinguish a wrong amount from a disappointing amount. The tax is based on statutory and local parameters, not on the sale price or the buyer’s occupation of the home. A British owner cannot obtain a refund merely because the property was empty after completion, because the buyer negotiated a lower price, or because the annual notice arrived after the deed. The strength of the claim depends on a concrete legal or factual defect that can be matched to the relevant year and notice.

II. “How can a British owner claim a refund of French taxe foncière?”

A. “What evidence and deadline apply to a French tax claim?”

The formal route is a réclamation contentieuse, meaning a written claim asking the tax administration to reduce, cancel or repay an assessment. Article L190 of the French Tax Procedure Code, the Livre des procédures fiscales or LPF, places claims seeking correction of an assessment error within the contentious tax jurisdiction. Its wording begins: “Les réclamations relatives aux impôts, contributions, droits, taxes, redevances, soultes et pénalités de toute nature”. The claim should not be confused with an informal request for information or a request to a notary to enforce a private clause.

For local direct taxes, including taxe foncière, the time limit must be calculated from the correct event. Article R*196-2 LPF provides that claims must be presented “au plus tard le 31 décembre de l’année suivant celle” of the relevant event, including the assessment being put into collection or the event that gives rise to the claim. The current text, including its treatment of local direct taxes, is available at Légifrance, Article R*196-2 LPF.

In a standard case, the notice and its date of collection will be the first dates to record. In a wrong-owner case, the relevant event may involve the transfer, publication, cadastral correction or another fact relied upon in the claim. Do not assume that the date of completion automatically resets the deadline. Do not wait for a buyer’s reimbursement dispute to be resolved if the tax deadline is approaching. Preserve the tax claim separately, even when a contractual action is also being considered.

Article R*197-2 LPF imposes a geographical filing discipline: “En matière d’impôts directs locaux, une réclamation distincte doit être présentée par commune”. If a British owner sold properties in two French communes, a single narrative letter may not be enough. Prepare a separate claim for each commune and identify each property, notice and tax year. This is particularly important for a portfolio held through personal ownership, where several notices can arrive together but are legally distinct.

The claim should be addressed to the competent SIP or submitted through the secure messaging service in the taxpayer’s French online account where that route is available. Keep proof of submission, including the date, the message content, the files attached and any acknowledgement. A British owner who has lost access to the French account should not simply abandon the claim. The notice, the tax number, the property reference and a clear written request can help the administration identify the file, while a lawyer or authorised representative may assist with the cross-border correspondence.

Article R*197-3 LPF lists formal requirements. It states that “Toute réclamation doit à peine d’irrecevabilité” meet the prescribed conditions. The official provision requires the disputed tax to be identified, a concise statement of the grounds and the relief sought, a signature and supporting tax documentation. The complete text is available at Légifrance, Article R*197-3 LPF. A typed English explanation can be useful, but the claim should still identify the French legal terms and the exact notice in a way the tax office can process.

A practical evidence file should contain the following documents:

• the complete French tax notice, including the tax year, property address, cadastral reference, amount and payment reference;
• the notarised deed showing the date and legal nature of the transfer, together with the relevant tax and charges clause;
• proof of publication or registration and any evidence that the cadastral mutation was requested or completed;
• the completion statement, handover record and correspondence that may establish the factual timeline without confusing it with the legal transfer date;
• bank evidence showing payment, duplicate payment or an unexplained debit, with the relevant transaction clearly identified;
• calculations showing the amount assessed, the amount legally due and the exact reduction or repayment requested;
• documents supporting a relief, correction or change affecting the taxable property, such as official decisions, demolition evidence, technical reports or prior exchanges with the SIP; and
• the buyer’s contact details and the relevant correspondence if a separate prorata reimbursement is also being pursued.

Keep the original French documents and provide an English explanation as a guide, not as a substitute for the official evidence. If the administration requests a French translation, obtain a reliable translation of the material that matters rather than sending a long bundle with no index. A short chronology is often more persuasive than several unlabelled attachments: ownership on 1 January, deed signature, publication, notice date, payment date, discovery of the error, contact with the SIP and submission of the claim.

The claim should state the requested outcome precisely. For example: cancel the 2026 assessment because the claimant was no longer the legal owner on 1 January; reduce the assessment by the amount attributable to an omitted statutory relief; or repay the duplicated payment. If the claim is based on a sale clause, say expressly that the clause is relied on against the buyer and is not presented as a request to alter the tax office’s legal debtor. Precision avoids sending the administration a contractual dispute when the actual request is a statutory tax correction.

Where the issue concerns an annual notice already paid, ask for a dégrèvement and the repayment of the excess. Where the bill remains unpaid, state the contested amount and consider the payment-suspension procedure described below. The two positions should not be mixed: a request for reimbursement from a buyer does not suspend a French tax debt, and a French tax claim does not automatically compel the buyer to perform the deed.

B. “What happens after the claim: payment, response and court appeal?”

Submitting a claim does not normally make the tax disappear while the administration examines it. Service-Public advises taxpayers to pay by the due date even when they are contesting the assessment, unless the proper suspension mechanism is used. This is especially important for a British owner who may assume that a pending email exchange with the SIP protects against collection. Keep a copy of the notice and monitor the French online account or correspondence address for payment reminders.

If there is a serious, quantified dispute, the claimant can expressly request a sursis de paiement, meaning a suspension of payment for the contested part. Article L277 LPF permits the taxpayer who has made the request in the claim and specified the disputed amount “à différer le paiement de la partie contestée de ces impositions et des pénalités y afférentes”. The full rule is available at Légifrance, Article L277 LPF.

The suspension is not an informal pause. The claim must identify the amount or bases of the reduction sought, and guarantees may be required above the statutory threshold. The tax accountant, bank or lawyer handling the matter should check the consequences before relying on it. A request that merely says “I disagree” without a calculation may not give the protection the taxpayer expects. If the disputed amount is modest, paying while preserving the claim may be administratively safer, subject to the facts and the advice received.

The administration has a response framework. Article R*198-10 LPF states that it “statue sur les réclamations dans le délai de six mois suivant la date de leur présentation”. If it needs more time, it must notify the taxpayer before the six-month period ends and specify the additional period, which cannot exceed three months. A rejection in whole or in part must be reasoned. The current official wording is available at Légifrance, Article R*198-10 LPF.

Record the date on which the claim was properly presented, not merely the date on which you drafted it. Save the acknowledgement and calculate the six-month point in a calendar. If the SIP asks for further evidence, answer promptly and keep the exchange in the same file. A request for documents does not justify allowing the original claim deadline to pass, and the absence of an answer does not mean that the taxpayer should stop monitoring the matter.

If the administration grants the claim after payment, the repayment rules may include interest in the situations covered by the LPF. Article L208 provides that “les sommes déjà perçues sont remboursées au contribuable et donnent lieu au paiement d’intérêts moratoires” when the statutory conditions are met. The official text, including the rule on interest running from payment in the relevant cases, is available at Légifrance, Article L208 LPF. Do not calculate interest as if it were automatically due on every negotiated buyer reimbursement: this provision concerns the tax administration’s dégrèvement and the conditions set by tax law.

A refusal or partial refusal should be read carefully. Identify whether the SIP rejected the legal basis, the evidence, the deadline, the amount or only the request for a particular form of relief. Sometimes the administration accepts a correction to the taxpayer but rejects the private prorata claim because that issue belongs between seller and buyer. Sometimes the response says that the notice is correct but leaves open a payment-allocation issue. The next step depends on that reasoning.

Article R*199-1 LPF governs the court route after an administrative decision. It provides that “L’action doit être introduite devant le tribunal compétent dans le délai de deux mois” from receipt of the decision. If no decision is received within six months, the taxpayer may, in the circumstances described by the provision, refer the matter to the competent court after that period. See the official text at Légifrance, Article R*199-1 LPF.

The competent court for an assessment dispute is generally the administrative court with territorial jurisdiction over the tax authority or property, but the filing position should be checked for the specific claim. A British owner should not assume that a county court in England can order the French tax office to cancel a French assessment. The court application should identify the contested notice, the prior claim, the administration’s response or silence, the legal grounds and the precise reduction requested.

That administrative litigation is separate from an action against the buyer. If the tax was correctly established in the seller’s name and the deed contains a binding reimbursement clause, a civil claim may be needed to recover the buyer’s share. The tax court cannot rewrite the deed merely because the seller feels that the economic result is unfair. Conversely, a successful contractual recovery does not prove that the tax assessment was wrong. The parties can have a valid reimbursement dispute even where the French tax office has acted perfectly correctly.

Cross-border evidence makes early organisation worthwhile. The deed may be held by the notary, the notice may be in the French online account, payment may have been made from a UK bank, and the buyer may have moved before the error is discovered. Create one dated file containing the French notice, the deed, the land-registration evidence, the payment trail and all messages. Use the same property description throughout. If the French address has accents or a shortened commune name, copy it exactly from the notice and cadastral record.

Before filing, test the claim against four questions. First, was the claimant the legal debtor on 1 January for the year in dispute? Second, what exact error or statutory right is being relied on? Third, what document proves that error? Fourth, what is the correct deadline and was the claim sent to the right office for the right commune? If any answer is unclear, obtain advice before the deadline rather than sending an expansive but unfocused complaint.

The 2026 notices also create a practical timing issue because many owners receive the bill while living in the United Kingdom or while a sale file is still being closed. The government’s current information on the calculation and payment calendar is available through the French Ministry of the Economy’s property-tax guidance. Treat the publication of a new notice as a prompt to review the year, address, owner, amount and payment status, not as proof that a refund is available.

A letter to the SIP can be short if the evidence is well indexed. State the tax year and notice number, identify the property and commune, explain the legal error in chronological order, cite the relevant CGI or LPF provision, calculate the requested reduction, attach the proof and ask for written confirmation. If the claim is in English, include the French labels from the notice and a French summary of the relief sought where possible. Do not include a speculative list of every tax rule that might apply; an administration can assess a precise claim more easily than a general complaint.

If the administration updates the account but does not repay the money, ask for the accounting status of the dégrèvement and the repayment reference. If the tax was paid by direct debit, check that the refund is not being sent to a closed French bank account. If it was paid from a UK account, provide the requested bank details through a secure channel and retain proof of the message. A payment delay is different from a refusal on the merits, so ask the SIP to distinguish those issues in writing.

The safest practical sequence for a British owner is therefore: preserve the notice and deadline; read the deed’s tax clause; check ownership on 1 January; verify publication and cadastral data; quantify any real assessment error; file a separate claim per commune; expressly request payment suspension if needed; monitor the six-month response period; and keep a separate contractual demand ready if the dispute is with the buyer. That sequence prevents the common mistake of asking the wrong party for the wrong remedy.

Conclusion

A British owner who sells a French property during the year will usually remain the person assessed for the full annual taxe foncière because the French rules look to ownership on 1 January. A prorata clause in the deed can support reimbursement by the buyer, but it does not usually create a tax refund. A refund claim becomes credible when the notice names the wrong legal debtor, applies the wrong property or calculation, omits a statutory relief, records a duplicate payment or must be corrected after a legally effective retrospective cancellation of the transfer.

Start with the notice, the deed, the publication evidence and the payment record. Then choose the route: a formal réclamation to the French tax administration for an assessment error, a contractual demand to the buyer for a valid cost-sharing clause, or both where the facts support separate claims. Protect the deadline under Article R*196-2 LPF, identify the commune and tax year, quantify the requested reduction and keep proof of submission. If the answer is negative, the reasoned decision and the two-month court period under Article R*199-1 LPF become the next milestones.
