Avis de taxe foncière en ligne
The heading is the term used on the official page, not a quotation from the letter itself.
What it is
An email saying the avis de taxe foncière has been posted in the espace particulier on impots.gouv.fr, under «Documents». People who chose the online avis get it this way: no paper avis follows.
What the rules provide
The rules provide for payment by the date on the avis, even when a réclamation has been filed. Late payment carries a 10% surcharge.
Deadline
The date is on the avis. In 2026: 15 October by cheque, transfer or cash (allowed only if the amount is €300 or less), 20 October online. The tax can be contested until 31 December of the year after the year of mise en recouvrement.
Usual steps
- Log in to impots.gouv.fr and open the avis under «Documents».
- Check the property and the amount, find the payment date on the avis.
- Pay online in the espace particulier, or with the flashcode on the avis in the impots.gouv app.
