Benchmarks for a municipality and a type of property

Choose a municipality and a type of property: the page shows the rates and tariffs that apply there and the asking prices of listings on this site. No total is computed.

Local taxes

Business property tax (cotisation foncière des entreprises, CFE) is calculated on the rental value of the property used for the business, to which a rate voted by the municipality or intercommunal authority is applied. The overall rate for each municipality of Val-d'Oise and its rate of property tax on buildings are given by the tool above.

Where the rental value is low, CFE is calculated on a minimum base, set by the municipality within a range that depends on turnover. A company is exempt from CFE in the year it is created; the following year its tax base is halved. It is also exempt if its turnover did not exceed €5,000.

The table of rates for every municipality is on the page Local taxes, municipality by municipality.

Development tax

The development tax (taxe d'aménagement) is payable once, on construction or extension work requiring planning permission. It is calculated as: taxable floor area × flat-rate value × rate. In 2026 the flat-rate value is €1,011 per m² in Île-de-France; it is halved for industrial or craft premises and for warehouses.

Three rates are added together: the municipal share, voted by the municipality (1% to 5%, up to 20% in certain areas), the departmental share (2.5% in Val-d'Oise) and the regional share (1% in Île-de-France).

Taxes specific to Île-de-France

The annual tax on offices is payable each year by the owner of offices, retail premises, storage premises or parking areas located in Île-de-France. In Val-d'Oise, municipalities in the Paris urban unit are in zone 3 and the others in zone 4; by way of exception, some municipalities in the urban unit benefit from the zone 4 rate.

The tax on the creation of offices, retail premises and warehouses is payable once, when such premises are built, rebuilt or extended. In Val-d'Oise, Argenteuil is classified in zone 2, municipalities in the Paris urban unit in zone 3 and the others in zone 4.

The mobility payment (versement mobilité) is a contribution paid by employers with at least 11 employees, based on wages and collected by Urssaf. Its rate depends on the municipality: 2.01% in 65 municipalities of Val-d'Oise and 1.60% in the other 118.

Numbers of municipalities: counted in the Urssaf table.

Labour costs

The gross hourly minimum wage (Smic) is €12.31, i.e. €1,867.02 gross per month for a 35-hour week.

In 2024 the average net monthly full-time-equivalent wage in the private sector was €2,644 in Val-d'Oise, compared with €2,733 in France.

The total cost of an employee to the employer depends on pay, social contributions and applicable reductions. Urssaf provides an official simulator that includes the 2026 scales; this page does not redo that calculation.

Business property

There is no official source for business property rents. The figures below are the asking prices of listings published on this site at Oct. 5, 2026: they are neither market rents nor transaction prices.

Method

1. Scope: the 546 listings published on the site, of which 296 were updated less than 24 months ago; the other 250 are excluded.
2. Type: five non-overlapping groups. A listing that mixes non-comparable uses (for example retail and offices) is not counted: 25 listings.
3. Unit: the price is read from the text of the listing, and only if it states its unit (euros per m² per year for a rent, euros per m² for a sale). An amount with no unit, in francs or “on request” is excluded: 52 listings for rents, 26 for sales. For a range, the lower bound is used. A total sale price is converted to a price per m² when the listing has a single floor area; sales of goodwill are excluded.
4. Inconsistent listing: several different prices in the same text, or an entered amount that contradicts the text: 6 listings excluded for rents, 4 for sales.
5. Outlier: within each type, a value more than one and a half times the interquartile range below the first quartile or above the third is excluded: 6 rents, 2 sale prices.
6. Threshold: no figure is published from fewer than 5 listings.

The only official reference available is the sales of industrial, commercial and similar premises recorded by the tax administration. From January 2021 to December 2025 their median price was €2,206 per m² in Val-d'Oise (2,480 sales), compared with €1,473 in France. This category covers very different properties: the median does not describe a specific type of property.

Energy and utilities

This page publishes no tariff for electricity, gas or grid connection: we have not found an official benchmark that applies to every business. For the electricity connection of business premises, Enedis, the distribution grid operator, describes the procedure and takes applications online.
