Overview

• Franceinfo’s new map shows the taxe foncière rose 37.3% on average from 2014 to 2024, helping raise €53.6 billion in 2024 according to DGFIP data.
• The steepest jumps appear in Mayotte, with an average increase of about 285% and an eightfold surge in Pamandzi tied to cadastral and implementation issues.
• In mainland France, Paris recorded an 88% rise over the decade following a 2022 municipal rate hike, while parts of Yvelines also saw sharp climbs, including +139% in Achères.
• The tax is owed by the owner as of January 1, with sales commonly splitting the cost pro rata temporis, and 2025 base valuations were revalued by 1.7%.
• Exemptions and remedies remain available, including relief for certain low‑income seniors and disabled beneficiaries, two‑year exemptions for new builds or major improvements, potential local incentives for energy works, and the right to request an evaluation sheet and file a motivated claim; the separate household‑waste levy is not covered by these rules.
