Local taxation: AI and satellite imagery strengthen controls on tax bases

The modernization of tax auditing undertaken by the French tax authorities is gathering pace.

In particular, these tools can be used to cross-reference cadastral, declaratory and visual data to detect areas that have been omitted, undervalued or assigned to an inappropriate category.

These include truck parking lots, traffic areas, outdoor storage areas and certain commercial surfaces benefiting from reduced weightings.

Areas targeted by controls

  • Parking spaces and truck parks
  • Traffic areas and lanes
  • Outdoor storage areas
  • Outdoor retail space with reduced weightings

Far from theoretical
