You can pay the
taxe d'habitation online prior to 20th December for holiday homes. You are now to late if you reside in France (the deadline was 15/20th Oct).
See on your tax (avis d'imposition) the different reference numbers (numéro fiscal, Référence de l'avis, etc) and the web site (click
here for link to the official tax office web site). It is rather straight-forward.
