Development tax: how much in 2024?
Publié le 08 février 2024 - Directorate for Legal and Administrative Information (Prime Minister)
Do you want to build a garden shed, a house extension or a swimming pool? Do you know that the owner has to pay a development tax for this work? Service-Public.fr reminds you of how it is calculated and the amounts applicable in 2024.
The development tax is a local tax levied by the municipality and the department and, only in Île-de-France, by the region. It is mainly used to finance the public facilities (networks, roads) needed for future construction and development.
It is not an annual tax, it is due only when certain construction works are carried out.
Which operations are involved?
The development tax applies to all development, building, reconstruction and expansion operations of buildings or installations, which require a city planning authorization (building or development permit, prior declaration).
It applies as soon as a surface bounded by walls and covered shall be created, provided that the area exceeds 5 mths2 and the height of the ceiling is greater than or equal to 1.80 m.
What rate is applied for this tax?
The value of the project is calculated either per unit (tent site, parking space, wind turbine...) or per m² of surface area (swimming pool, photovoltaic panel...). The percentages (rates) for the municipalities, departments and regions are applied to this value.
The development tax is the sum of these results.
- The annual rate of municipal share may vary from 1 % to 5 %. It can go up to 20% in some sectors.
- The annual rate of departmental share is the same for the entire department. It shall be limited to a maximum of 2,5 %.
- The regional share rate set by the Regional Council of Île-de-France may differ from one department to another within the limit of 1%.
Calculation and amount of development tax
In order to calculate the amount of the development tax, the taxable area of the created construction by the annual value per m2, and then multiply that result by rate voted by the local authority concerned by the tax.
Values per m2 are updated on 1er January of each year according to the latest construction cost index published by the National Institute of Statistics and Economic Studies (INSEE).
At 1er January 2024, the latest construction cost index published by INSEE is that of 3e quarter 2023, the 2106 index (index of 3e quarter 2022: 2037).
For 2024, the values applied in the calculation of the development tax are:
- the annual value per m2 is €914 (excluding Île-de-France) and €1,036 for municipalities in Île-de-France;
- the standard value of swimming pools shall be €258 per m2 ;
- the standard value of outdoor parking spaces shall be €3,000 per location (up to € 6 000 per location, subject to the decision of the local authority).
Please note
other developments are subject to a specific flat-rate assessment: tents, caravans, mobile homes, light recreational dwellings, wind turbines of more than 12 m, photovoltaic panels on the ground.
Solar thermal panels and parking areas for 2 wheels are not taxed. Similarly, a pergola, an arbor or a terrace are not taxable because they are not closed and covered.
Report and pay development tax
You must report the elements necessary to calculate the tax at the same time as your property return, within 90 days of the completion of the work.
Go for this in your secure space on the tax website, tab “Real estate”. Use the accommodation declaration form.
If the amount of your development tax is more than €1,500, you can pay it in 2 installments: you will receive two payment documents to be paid within 90 days and then 9 months after the completion of the work.
Please note
some buildings qualify for a rebate or exemptions. Find all the information on the sheet of Service-Public.fr Development tax (TA).
Warning
the manner in which the development tax is declared and paid varies if your application for city planning authorization has been filed before or after 1er september 2022.
