The French Ministry of the Economy has confirmed reports, initially published by Le Parisien, that an extensive update to property descriptions will affect 7.4 million homes starting in 2026. This initiative is part of a large-scale operation by the tax authority, the DGFiP (Direction Générale des Finances Publiques), to verify and correct land registry data.

Paid by around 32 million property owners, the taxe foncière (property rates) is expected to rise by an average of €63 per affected home, due to this update of the tax base, representing an additional €466 million for local authorities.
