Who this guide is for

Section actions
  • You if your property tax has increased sharply for no obvious reason
  • You if the cadastral surface or description of your property is incorrect
  • You if your property is degraded/unsanitary but tax remains full

To be prepared in advance

Section actions
  • Property Tax Notice of the year under appeal
  • Cadastral matricle (section, number) — indicated on the opinion
  • Evidence: cadastral plan, expert reports (diagnostics), degradation photos, repair estimate

Step-by-step procedure

Section actions
  1. 1Check the details on impots.gouv.fr → particular space → « Services » → « Property ». Compare surface, batch number, comfort class with reality.
  2. 2Deadline for challenge: 31 December of the year of receipt of the notice for the contentious claim. For error of material characteristic — no strict time limit, but to be filed before 31 December.
  3. 3Litigation claim (general procedure): send a mail (recommended with AR) or online on impots.gouv.fr to the Property Tax Centre. Indicate number, justification, revision requested. Attach the evidence.
  4. 4Grounds for challenge: area error (range ≥10 %), characteristics (comfort, exposure), cohesion elements (dependencies, swimming pool absent), rental value 2× above the communal average, easements, decline not taken into account (fire, natural disaster).
  5. 5For material errors — ask for a review of the features at the Tax Centre (formality, often free of charge).
  6. 6For excessive rental value — the claim is more complex. There is a need to demonstrate inconsistency with comparable properties in the municipality; the DGFiP can request expertise. Prepare for a refusal at first instance.
  7. 7Recourse in excess of power: for an illegal decision (e.g. illegal taxation of vacant premises) — before the administrative court within 2 months of the response of the DGFiP.
  8. 8DGFiP response generally within 6 months. In case of refusal — mediation DGFiP (Ombudsman of economic and financial ministries), then Administrative Tribunal (3–18 months). Tax lawyer fees: 500–3 000 €.

Common mistakes

Section actions
  • Allow the deadline of 31 December of the year of receipt of the notice to pass — the main reason for rejection.
  • Contest the only communal rates — the rates are fixed by the municipal council, separate recourse (Administrative Court).
  • To believe that any disagreement with the assessment is a reason — material proof of error is required.
  • Do not use the free feature revision option (hardware error) and go straight to litigation.
  • Pay the tax in full during the challenge — payment remains mandatory to avoid penalties; refund after decision.
