Taxe foncière 2026: when your avis arrives and the date you actually have to pay

Taxe foncière is the annual property tax, and it is charged to whoever owned the property on 1 January of that year. If you rent, you will never receive one in your own name. If you own, this is the bill that lands every autumn, and 2026 is running to its usual calendar with two different payment deadlines depending on how you pay.

When the avis appears

• Online, if you pay in one go: from 27 August 2026 in your espace on impots.gouv.fr.
• Online, if you pay monthly (mensualisation): from 19 September 2026.
• On paper, if you pay in one go: posted between 24 August and 21 September 2026.
• On paper, if you pay monthly: posted between 21 September and 9 October 2026.

Those are ranges, not a single national post day, which is why a neighbour can be holding their avis while yours has not moved. If you have opted for the dématérialisation of your documents, no paper is sent at all and the avis exists only in your espace.

The two deadlines

There is no single date, and the later one is the reward for paying online.

• Paying by any non-online method: 15 October 2026.
• Paying online, by internet, smartphone or tablet: 20 October 2026 at midnight.

Above €300 you have no choice

Dematerialised payment is compulsory for any personal tax above €300. Over that amount, paying by cheque, by card at a counter, in cash or by bank transfer is not authorised. What remains is paying online, setting up a prélèvement à l'échéance, or moving to monthly instalments. Most taxe foncière bills on a whole property clear €300 comfortably, so for most owners this is the rule that applies.

The check worth doing before you pay

Open “Gérer mes biens immobiliers” in your espace and confirm that every property listed under your name is described correctly and that the occupation status is right. The same database drives the taxe foncière and the taxe d'habitation on second homes, and a property you sold, a flat recorded as vacant that is actually let, or an address that was never updated after a move all produce bills that look official and are simply wrong. Correcting the record is how you stop it repeating next year.

If the amount is a problem

Ask before the deadline rather than after it. A délai de paiement requested through the secure messaging in your espace particulier is treated very differently from a payment that simply fails, and the trésor public grants staged payments routinely. If you would rather never face a single autumn bill again, switching to mensualisation spreads next year's taxe foncière over monthly instalments instead.

An avis de taxe foncière runs to several pages of cadastral references, base d'imposition tables and local authority rates, with the two numbers that matter, the amount and the date, printed somewhere in the middle. Upload yours to Mes Papiers and we will tell you in English what you owe, by when, and which of the two deadlines is yours.
