Verified 28 February 2024 - Legal and Administrative Information Directorate (Prime Minister), Ministry of city planning

A company or individual who plans to carry out work affecting the basement must pay a preventive archeology charge (or royalty for certain works). The amount of the tax and the formalities to be carried out vary depending on the nature of the work.

General case

The Preventive Archeology Tax applies to all works which the following 3 conditions :

  • The works constitute a construction, reconstruction, extension or improvement operation of building
  • The work is subject to a system of declaration or prior authorization (e.g. building permit or development permit)
  • The work has a impact on the subsoil, regardless of depth.

Please note

Work which does not affect the subsoil is subject only to the development tax.

The Preventive Archeology Tax is not due for the following work:

  • Buildings and fittings assigned to a public or public utility. For example, buildings intended to receive an assistance, charitable, health, educational or cultural, scientific or sporting assignment. Provided that the construction remains in the same use for a minimum period of 5 years.
  • Premises for dwellings and accommodation financed with a assisted integration rental loan (WOUND)
  • Agricultural premises. Floor areas of production greenhouses, premises for holding crops, housing animals, storing and maintaining agricultural equipment, premises for the production and storage of products for agricultural use, premises for processing and packaging farm products, in leisure riding centers, building areas for equestrian activities, etc.
  • Buildings assigned to horse riding (in equestrian recreation centers)
  • Facilities provided by a plan for the prevention of foreseeable natural risks, a technological risk prevention plan or a mining risk prevention plan
  • Buildings destroyed or demolished for less than 10 years, reconstructed identically
  • Constructions of which the area is less than or equal to 5 m²
  • Installations for laying and operating underwater information cables
  • Ancillary surfaces, for parking, arranged above or below the buildings or integrated into the building, in a vertical plane.

Please note

The preventive archeology tax is not due when the The work does not affect the basement (e.g. elevation of an existing building, land use without foundation or earthworks).

When the application forcity planning authorization, the elements justifying the exemption must be attached to the file.

The amount of the preventive archeology fee is calculated by multiplying the following 3 elements :

  • Taxable area
  • Lump-sum value
  • Rate

The calculation formula is therefore as follows: Taxable area x Lump-sum value x Rate.

Taxable area

The taxable area is the sum of the floor area for each level (floor surfaces) closed and covered, under a ceiling height of more than 1,80 meters and including foundations. This area is calculated from the inner surface of the facades. It therefore does not take account of the hoppers.

Example :

A building that is open to the outside with one less facade partition (e.g. pergola or arbor) is not included in the taxable area. The same goes for an open-air facility such as a terrace. On the other hand, a covered and enclosed veranda with foundations is taxable.

Lump-sum value

The taxable area is multiplied by one standard value per square meter, updated annually.

General case

The standard value (in m²) is fixed at €914.

Île-de-France

The standard value (in m²) is fixed at €1,036.

One abatement of 50% shall be applied to the flat-rate value for the following premises:

  • Premises for use of main dwelling for the first 100 m²
  • Residential and accommodation premises benefiting from an assisted loan from the State (excluding WOUND: titleContent, since they are already exempt from tax)
  • Premises for industrial or craft use
  • Warehouses and sheds not open to the public which are commercially operated
  • Covered parking lots that are commercially operated.

In addition, a specific standard value applies to certain developments.
