Missing a French taxe foncière deadline can be alarming when you live in Britain, use a UK bank account or only visit your French property for part of the year. Taxe foncière is the annual French local property tax charged on French property, principally according to the ownership position on 1 January. Brexit does not remove it, and a French tax notice is not treated like a UK council-tax bill: the French notice, the statutory dates and the payment route control what happens next.

A late payment can produce a 10% majoration, meaning a statutory surcharge. That does not mean every disputed bill should simply be paid without checking it. The practical question is whether the principal tax is correct, whether you were properly informed, whether a payment was actually made or rejected, and whether the problem is legal error, financial hardship or an exceptional event. Each situation has a different remedy.

The safest first response is to secure the notice and proof of the payment position, pay any amount that is not genuinely disputed if you can, and choose the correct French procedure: a réclamation contentieuse (a formal tax claim), a remise gracieuse (a discretionary request for relief), or a sursis de paiement (a request to defer the disputed payment). If a mise en demeure de payer or a bank seizure follows, the recovery deadlines become urgent. This guide sets out the legal sequence for a British owner and the evidence that should accompany each step.

I. What happens when a British owner misses the French taxe foncière payment deadline?

A. Who owes it, what date controls, and when does the 10% surcharge arise?

The starting point is the property, not the passport. Article 1380 of the French Code général des impôts (CGI, the General Tax Code) states that the tax is established annually on built properties situated in France, subject to statutory exemptions. The official wording begins: La taxe foncière est établie annuellement sur les propriétés bâties sises en France. The rule therefore concerns the French building even when the owner is resident in the United Kingdom, has a UK pension, pays UK taxes or occupies the property only as a holiday home. The official text of CGI article 1380 is the correct reference for that basic charge.

Article 1400 of the CGI addresses the name under which the assessment is made. Its first paragraph provides that, subject to specific provisions, every built or non-built property must be assessed in the name of the current owner: toute propriété, bâtie ou non bâtie, doit être imposée au nom du propriétaire actuel. This is why a notice can remain payable even when the owner has moved back to England, changed tax residence, appointed a French property manager or stopped using the property. The current Légifrance version of CGI article 1400 should be checked if the ownership record or an exemption is in dispute.

The decisive annual date is normally 1 January. Article 1415 of the CGI provides that the property taxes are established for the whole year according to the facts existing on 1 January of the assessment year. The official formula is d’après les faits existants au 1er janvier de l’année de l’imposition. That rule answers many practical questions: a change in occupation during the year does not automatically cancel the year’s assessment; a later change of address does not move liability to the United Kingdom; and a disagreement about who owned the property on 1 January is a substantive issue to put into a tax claim, supported by the relevant deed or land-register evidence. See CGI article 1415 on Légifrance.

The notice is called an avis d’imposition, meaning the tax assessment notice. It identifies the property, the amount, the date of mise en recouvrement (the date on which the amount is formally placed for collection) and the payment deadline. Article L. 253 of the Livre des procédures fiscales (LPF, the Book of Tax Procedures) requires the notice to mention those dates. The official LPF article L. 253 is useful when a notice is incomplete or the date on it does not match the administration’s later recovery assertion.

For 2026, the official government timetable says that non-monthly property-tax notices become available from 27 August and monthly-payment notices from 19 September. The stated deadline is 15 October for payment by methods other than online payment when the amount is below €300, and 20 October for online payment. An amount of €300 or more generally has to be paid online. These dates are a practical calendar for 2026, not a substitute for the date printed on your own notice. The government’s official 2026 taxe foncière timetable should be consulted if the notice arrives late or you use monthly direct debit.

An online payment may have a short statutory or administrative extension compared with a paper payment. The tax authority explains that, for an online payment, the bank debit can occur later than the date on which the payment instruction is entered. That is different from ignoring the notice: retain the confirmation screen, transaction reference and bank statement. If a UK card or transfer fails, take a screenshot of the refusal and use the French tax account or the payment instructions on the notice immediately. A foreign bank account does not itself create a defence to the tax.

The surcharge is dealt with by article 1730 of the CGI. Its first paragraph provides, in substance, that delay in paying the listed taxes, including property taxes, gives rise to a 10% surcharge. The statute says: Donne lieu à l’application d’une majoration de 10 % tout retard dans le paiement. The official text of CGI article 1730 must be read with its timing provisions. It refers to amounts in a tax roll or recovery notice that have not been paid within the statutory period following the date of collection or notification, and it contains a rule preventing the surcharge being applied before 15 September for current-year assessments. It also provides a limited postponement of certain surcharge dates for taxpayers using online payment.

That wording matters because the printed deadline, the date of formal collection, the date of notification and the method of payment can all be relevant. A British owner should not assume that the 10% is lawful simply because the tax office has added it, but should also not assume that the surcharge disappears merely because the notice was confusing. The question is evidence-based: what was issued, when was it made available or sent, how was it notified, what was paid, and what statutory ground is being relied upon?

The Conseil d’État, France’s highest administrative court, has addressed notice problems. In its decision of 5 January 1994, no. 99616, concerning a taxpayer who said the notice had not been received, it stated that l’impôt n’est exigible qu’à compter de la date où le contribuable a été informé. The decision is available at Conseil d’État, 5 January 1994, no. 99616. That authority does not make every postal difficulty decisive. It shows why the administration must be able to establish information about the assessment before relying on an enforceable debt, while the taxpayer must show what happened to the notice and what steps were taken after discovering the debt.

Brexit and the UK–France double-tax treaty must be kept in their proper place. The treaty may allocate taxing rights over particular income or capital items and can prevent the same income being taxed twice. It is not a general exemption from a French local property charge. The British government’s guidance on living in France directs residents to the French tax authority for their French obligations, while the official UK–France double-taxation convention deals with the taxes and income categories covered by that instrument. A treaty argument may be relevant to a separate UK pension, rental-income or capital-gain question; it does not, without a specific legal provision, cancel the taxe foncière attached to a French property.

There is also a difference between liability and affordability. Liability asks whether the correct person, property and year have been assessed. Affordability asks whether a person who owes the tax can pay it on time. The first question normally leads to a formal tax claim. The second may justify a payment arrangement or a request for discretionary relief. Treating financial hardship as if it were an error in the assessment can produce a badly framed application and leave the surcharge unresolved.

B. What should you pay, preserve and check before arguing?

Begin with a one-page chronology. Write down the tax year, the date you first saw the notice, the date printed as the payment deadline, the date you attempted payment, the account or card used, the result returned by the bank, and every later message from the Direction générale des finances publiques (DGFiP, the French public-finance administration). Include whether the notice was sent to an old French address, a UK address, a property manager or a secure online mailbox. Keep the envelope, PDF metadata, portal messages and bank records. A short chronology is often more persuasive than a long explanation of Brexit.

Then separate four questions that are often mixed together:

• Is the assessment correct? Check the property address, the owner on 1 January, the tax year, the taxable basis and any exemption or relief claimed.
• Was the principal paid? Match the notice amount against the bank debit, online receipt or direct-debit record. A payment made to the wrong reference may require tracing rather than a new payment.
• Was the delay excusable? Identify a documented bank outage, serious medical event, force majeure or an administrative failure, rather than relying only on the fact that the owner was abroad.
• Is the dispute about collection? A seizure, demand for payment or calculation of the remaining debt is a recovery issue with its own rules. It is not automatically a second opportunity to reopen the tax assessment.

If the principal is correct and you can pay it, paying the undisputed amount promptly can reduce the risk of further collection action. State in writing what the payment covers and retain the proof. Payment does not necessarily waive a properly framed claim about an unlawful surcharge, but the wording and procedural route should be checked before sending a payment that is intended to be contested. If you cannot pay at once, request an instalment arrangement and a remission at the same time, while explaining that the request is not an admission that an incorrectly calculated principal is due.

If the amount or owner is wrong, do not rely on a telephone call alone. A phone adviser may correct an administrative detail, but a formal claim creates a dated record and identifies the relief sought. Article L. 190 of the LPF defines the réclamation contentieuse route for claims seeking correction of an assessment or calculation error, or the benefit of a legal or regulatory right. The statute describes these claims as relating to la réparation d’erreurs commises dans l’assiette ou le calcul des impositions. Read LPF article L. 190 on Légifrance before drafting the grounds.

If the problem is that the notice went to an obsolete address, compare the address in the notice with the address held in your French tax account and the address that you had formally reported. An address error may support a notice or notification argument, but it does not automatically erase the underlying tax. The separate article on challenging French tax on a British owner’s second home is a useful internal starting point for the wider property-tax and cross-border tax context; this article focuses on the missed-payment and recovery problem.

For a UK bank problem, preserve the exact rejection code and the bank’s time stamp. “The transfer did not go through” is weaker than a record showing that the bank blocked a euro payment, imposed a verification hold, closed the account, or refused a beneficiary. Add correspondence showing when you tried to resolve the block. If the bank held the funds but the French tax account was not credited, obtain the payment trace and ask the DGFiP to reconcile it against the tax reference. A bank problem can support a factual explanation and, in an exceptional case, a force-majeure argument; it does not create an automatic exemption.

Check whether your French tax account has another notice or a message about monthly payment. Owners who previously used monthly direct debit sometimes assume that a new year will be collected automatically after a bank change. Confirm the mandate, the account actually debited and whether a payment was rejected. A property manager’s silence is not the same as proof that tax was paid. Ask for the payment confirmation rather than accepting a general statement that “the taxes are handled”.

Finally, do not delay simply because you are waiting for a British tax adviser to explain the treaty. A treaty analysis can be important for income, pensions and gains, but the immediate French property-tax deadline continues to run. If an assessment is correct, focus on payment or hardship relief. If it is incorrect, formulate the legal error and request a payment suspension for the disputed part. If a recovery act arrives, move to the recovery procedure without waiting for informal correspondence to finish.

II. How can you remove or challenge the surcharge and prevent recovery action?

A. When should you file a tax claim, request a payment suspension or ask for remission?

The remedy should match the complaint. A British owner generally has three routes, which can be used in a coordinated way but should not be confused.

Problem	French route	What to ask for
The tax, owner, taxable basis, year, exemption or surcharge is legally or factually wrong.	Réclamation contentieuse	Correction, discharge or refund, with the legal ground and calculation.
The assessment is being challenged and payment of the disputed part would cause harm.	Sursis de paiement	Defer only the identified disputed amount and related penalties, expressly requested in the claim.
The tax is properly established but payment or the penalty creates genuine hardship.	Remise gracieuse	Full or partial discretionary relief, an instalment plan or a transaction, with evidence.

Formal tax claim. The contentious claim is the route for an error in the assessment or calculation, a missing legal entitlement or an unlawful penalty. Article L. 190 LPF is the anchor. The claim should identify the taxpayer, the property, the year, the notice number, the amount contested and the exact outcome requested. If only the 10% surcharge is challenged, say so; if the principal is also disputed, give the separate figures. Attach a copy of the notice, proof of ownership or status on 1 January, payment records, correspondence and a calculation showing the requested reduction.

The normal deadline for local direct taxes is important. Article R.* 196-2 LPF provides that claims concerning local direct taxes and related taxes must generally reach the tax administration by 31 December of the year following the relevant year of collection, notification, event or payment, depending on the applicable trigger. The current Légifrance section for LPF article R.* 196-2 should be checked against the notice and the facts. For a 2026 assessment, the ordinary notice-based deadline will often fall on 31 December 2027, but a different trigger or special rule can change the calculation. Do not wait until that outer date if collection is already underway.

Payment suspension. Article L. 277 LPF permits a taxpayer who contests the basis or amount of tax to defer the disputed part when the claim expressly asks for it and states the amount or bases of the claimed discharge. The official wording includes à différer le paiement de la partie contestée de ces impositions. See LPF article L. 277. This is not an automatic freeze merely because a claim has been uploaded. The request must be explicit, quantified and attached to a claim that actually contests the assessment. The administration may require guarantees under the applicable rules, particularly for a substantial amount.

A suspension request should therefore say which amount is undisputed and which amount is deferred. If the correct principal is €2,000 and only a €200 surcharge is challenged, do not write as though the entire notice is contested. If you cannot pay even the undisputed amount, explain that separate difficulty in the remission request and ask for an instalment arrangement. A suspension of the disputed amount and a remission of a penalty pursue different legal objectives.

Discretionary remission. Article L. 247 LPF allows the administration, on the taxpayer’s request, to grant full or partial remission of regularly established direct taxes where the taxpayer cannot pay because of hardship or indigence. It also addresses penalties and surcharges when they are final, and a transaction where they are not final. The statute begins: L’administration peut accorder sur la demande du contribuable. The official text of LPF article L. 247 makes clear that this is a discretionary power, not an automatic entitlement.

Article R.* 247-1 LPF directs a remission request to the territorial tax service connected with the place of assessment and requires enough information to identify the tax, generally with the assessment notice or a copy. The official wording of LPF article R.* 247-1 should be followed even when the owner lives in the UK. The French tax authority’s remission guidance explains that the request should be made to the relevant service, through the available secure channel, with evidence of the circumstances and ability to pay. It also warns that a remission request does not suspend the payment obligation.

The evidence should be specific. For financial hardship, provide income, pension, savings, essential expenditure, exceptional bills, exchange-rate impact and other debts, with sensitive material limited to what the administration needs. For a medical event, provide a proportionate certificate or record of the period that prevented action. For a bank failure, provide the payment attempt, rejection and complaint trail. For force majeure, explain why the event was external, unavoidable and directly connected to the missed payment; simply being outside France is not enough.

The Conseil d’État decision of 7 May 2025, no. 495329, is relevant to the last point. In Conseil d’État, 7 May 2025, no. 495329, the court accepted that a taxpayer may rely on un cas de force majeure when seeking discharge of the obligation to pay the 10% surcharge, but the facts still have to satisfy that demanding standard. The decision did not turn every foreign-account restriction into force majeure. Use it to frame an evidence-based argument, not as a promise that a UK banking difficulty will succeed.

A refusal of remission is also not an ordinary appeal on the whole tax calculation. In its decision of 18 April 2023, no. 461482, the Conseil d’État held that a refusal of a remission request can be brought before the administrative judge by an action for annulment, but only on limited grounds such as lack of jurisdiction, error of law, error of fact, manifest error of assessment or misuse of power. The principle is set out in Conseil d’État, 18 April 2023, no. 461482. The decision is a warning to put the strongest evidence before the DGFiP at the first stage rather than assuming a court will simply substitute a different view of hardship.

The remission application should be short enough to be read and detailed enough to be verified. A useful order is: identification; tax year and notice number; amount of principal and surcharge; chronology; why the assessment is correct or incorrect; why payment failed; financial or exceptional evidence; precise request; and a list of attachments. Use the French labels in the subject line, but explain the request in clear English if that is the language in which you can accurately set out the facts. A French translation of key documents can be added where the service needs it.

Do not ask the remission service to decide a title dispute, an ownership-on-1-January dispute or a calculation error as though it were a favour. Put those grounds in the contentious claim. Conversely, do not present an inability to pay as proof that the tax basis is wrong. The administration can consider both, but the requests should identify which power is being invoked.

B. What if you receive a formal notice, SATD or refusal?

Once the debt enters recovery, the vocabulary changes. A mise en demeure de payer is a formal demand to pay. A saisie administrative à tiers détenteur (SATD) is an administrative third-party seizure, commonly served on a bank or another person holding funds. It is not the same as a fresh tax assessment. The response must address the act received, the date of notification, the amount still due and the specific recovery complaint.

LPF article L. 257-0 A provides for a formal demand before the first enforcement act that generates recovery costs, subject to the statutory conditions. When the demand communicates tax sanctions, the text provides a period of 30 days before enforcement can be started in the circumstances described by the article. Read the official LPF article L. 257-0 A against the document actually received. A phone call from a collector does not replace an analysis of the written act.

At this stage, separate the merits of the tax from recovery. Article L. 281 LPF limits a recovery challenge: it cannot generally reopen the legal basis of the debt and can concern the formal regularity of the enforcement act, the obligation to pay, the amount after payments and the enforceability of the sum. The statute states that recovery challenges ne peuvent pas remettre en cause le bien-fondé de la créance. The Légifrance section for LPF article L. 281 is the starting point.

If the complaint concerns a SATD, missing credit for a payment, an amount already paid, lack of enforceability or a defect in the act, LPF article R.* 281-1 requires a written request supported by useful evidence to the competent service head. The official section containing LPF article R.* 281-1 sets out that route. Attach the notice, the demand, the SATD, bank statements, payment traces and any correspondence. Do not send only a general statement that the tax is unfair.

The deadline for a recovery challenge is short. Article R.* 281-3-1 LPF requires the request, on pain of inadmissibility, to be made within two months of notification of the relevant enforcement act. The official text of LPF article R.* 281-3-1 states the two-month rule. The Conseil d’État applied the importance of that time limit in its decision of 9 June 2021, no. 429919, involving property taxes and a bank seizure: the court referred to the requirement that the challenge be made dans un délai de deux mois. See Conseil d’État, 9 June 2021, no. 429919.

The service head must normally decide within two months of the request and acknowledge receipt. That is the rule stated by LPF article R.* 281-4, available in the official Légifrance text of LPF article R.* 281-4. If the response is adverse or there is no response within the applicable period, a further court route may be available, subject to the precise act and jurisdiction. Keep proof of the date on which the administration received the request; an online submission receipt is safer than an untracked email.

Jurisdiction is not a technical detail to leave until the end. A challenge to the merits of a direct tax generally belongs before the administrative court through the tax-claim route. A challenge to the formal regularity of an enforcement act may fall within the jurisdiction of the enforcement judge. In its decision of 4 February 2013, no. 336402, the Conseil d’État drew that distinction in a case involving property taxes, a surcharge and a third-party seizure. The decision is available at Conseil d’État, 4 February 2013, no. 336402. Sending a merits dispute to the wrong court can waste the short recovery period.

Prescription arguments are fact-sensitive. In its decision of 19 September 2014, no. 365934, the Conseil d’État considered older property-tax claims and concluded on the facts that le délai de recouvrement était expiré. The decision appears at Conseil d’État, 19 September 2014, no. 365934. A British owner should not copy an old limitation argument from a different notice. Establish the date of the assessment, every demand, every enforcement act and every payment before asserting that collection has expired.

The legal character of the 10% surcharge also matters. The Conseil d’État decision of 16 April 2010, no. 313456, available at Conseil d’État, 16 April 2010, no. 313456, confirms that the statutory surcharge provisions are applied according to their legal scope. If the administration has added 10% to an amount that is not covered by article 1730, or has treated a non-tax charge as a property-tax arrear, identify that precise error. A generic request to “cancel the fine” is less effective than showing the notice, calculation and statutory provision side by side.

If a remission request is refused, the DGFiP’s guidance may direct you to the conciliateur fiscal départemental, the departmental tax conciliator. That can be useful for reviewing a service failure or asking for a fresh administrative look, but conciliation does not suspend payment or court deadlines. Continue to protect the contentious-claim and recovery deadlines while using the conciliator. Do not withdraw a formal claim merely because a conciliator agrees to review the file.

Use the following recovery checklist as soon as a formal act arrives:

1. Record the exact date and method of notification, including the date a bank received a SATD.
2. Download the complete notice and every attachment from the French tax account; preserve the original files.
3. Calculate the principal, 10% surcharge, recovery fees, payments credited and balance separately.
4. Decide whether the complaint is about assessment merits, payment suspension, remission, recovery amount, enforceability or the form of the act.
5. File the appropriate written request with all evidence before the two-month recovery deadline where it applies.
6. Tell the bank or payment intermediary that the tax debt is being reviewed, but do not assume that a bank complaint stops the DGFiP process.
7. Obtain an acknowledgement and diary the administration’s two-month response period.

A short English chronology can accompany a French-labelled request. For example, the subject can identify “Réclamation contentieuse and request for sursis de paiement — taxe foncière [year] — notice [number]”. The body should then state the property, the 1 January ownership position, the amount disputed, the payment attempt, the reason for the delay and the relief sought. If the owner also seeks a remise gracieuse, create a separate heading in the same submission or a separate attachment so that the discretionary request is not mistaken for the legal claim.

There are practical signs that professional review is warranted: a seizure of a UK or French bank account; a notice issued to an owner who transferred the property before 1 January; a notice that cannot be connected to the property; a payment made but not credited; a refusal that ignores decisive evidence; several years of accumulated notices; or a dispute involving a trust, company or SCI. An SCI is a French civil property-holding company, and its tax treatment can change the analysis; a personal owner should not assume that an SCI article answers an individual assessment. Likewise, a property-tax dispute should not be redirected into the purchase process, which is a separate legal question.

For a British owner, the strongest file usually contains four folders: ownership and property records; tax notices and portal messages; payments and bank evidence; and hardship or exceptional-event evidence. Name each document with the year and date. Add a one-page calculation. This makes it easier to show the DGFiP exactly what should be corrected, what has been paid, what remains disputed and why the 10% surcharge should be removed or, at minimum, considered for discretionary relief.

Conclusion

A missed French taxe foncière deadline is manageable when the response is divided into the right legal questions. First establish whether the tax is correctly assessed against the person who owned the French property on 1 January. Next establish the notification, payment and surcharge chronology. If the assessment is wrong, file a documented réclamation contentieuse; if the disputed amount must be deferred, expressly request a sursis de paiement; if the debt is correct but genuinely unaffordable or the delay followed an exceptional event, seek a remise gracieuse with evidence. A formal demand or SATD triggers a separate, short recovery timetable. Brexit, UK residence and a foreign bank account explain the context, but they do not replace the French procedure. Acting early, quantifying the dispute and preserving every payment and notice record gives a British owner the best chance of containing the surcharge and stopping an avoidable escalation.
