Overview
- About 7.5 million dwellings are targeted for an automatic reassessment that counts amenities such as indoor bathrooms, toilets, running water and heating for the first time since the 1970s.
- Bercy estimates the change would yield roughly €460 million in additional revenue for local authorities.
- Facing backlash from across the political spectrum and property groups, the minister announced a short stakeholder consultation to consider adjustments to the calculation.
- Property tax burdens have already climbed sharply over the past decade, averaging +37.3% nationwide from 2014 to 2024, with far higher increases in cities such as Paris, Strasbourg and Limoges.
- Recent jumps stem from record majoration of cadastral values and the annual lawful revaluation (1.7% in 2025), while private analysis flags mid-sized and suburban towns like Massy, Vénissieux and Castelnau-le-Lez as relatively resilient for investors.
