Overview
- Tax files will be updated automatically to include standard amenities that translate into extra taxable surface (for example, water +4 m², bathtub +5 m², WC or lavabo +3 m² each, electricity +2 m², heating +2 m² per heated room).
- About 7.4 million dwellings are targeted—roughly 25% of houses and 15% of apartments—with an average €63 increase and an estimated €466 million in additional revenue for local authorities.
- The change will appear on 2026 property tax rolls, with bills due in October; owners will receive initial contacts early in 2026 and broader information in June, with significant variations notified individually.
- Owners who lack the listed equipment can contest the new assessments and seek tax relief, and the most dilapidated housing categories are excluded from the operation.
- Following sharp political criticism, the government has promised a progress update in the coming months while maintaining that the move improves efficiency and tax equity.
