Verified 31 January 2025 - Directorate for Legal and Administrative Information (Prime Minister)
You have obtained a building permit and you are looking for information on the development tax you have to pay? We bring you the information on its application, its calculation and the steps to be carried out.
General case
For which works is the development tax payable?
The development tax is charged for the following operations:
- Construction, reconstruction and expansion of a building
- Fitting-out or installation (e.g. outdoor parking, swimming pool, wind turbine, campsites)
- Change of destination from exempt premises to taxable premises (e.g. converting agricultural premises into housing).
It is payable following a city planning authorization:
The tax is also payable in case of construction or development without authorization or in breach of the authorization granted.
Who has to pay the development tax?
You have to pay the tax if you are in one of the following situations:
- Beneficiary of the authorization to construct or develop
- Responsible for illegal construction
- Beneficiary of the transfer of an authorization.
Who collects the development tax?
The development tax is composed of a municipal share and a departmental share which are paid to the General Directorate of Public Finance (DGFIP). The tax department then returns it to the municipality and department concerned.
A taxable value is assigned to your project.
Percentages (communal rate, departmental rate) are applied to the defined value. The sum of the results obtained gives the amount of the development tax.
What is the applicable rate?
The annual rate of the municipal share may vary by 1% to 5%. It can reach up to 20% in certain sectors.
The annual rate of the departmental share is the same for the entire department. It is fixed at 2.5% at the most.
Depending on the case, the tax shall be payable at the rate applicable on one of the following dates:
- Issue of the building permit or to arrange
- Issue of the amending permit
- Date of a implied permit to build or develop
- Decision not to oppose a prior declaration
- Minutes recording the completion of constructions carried out without authorization or in breach.
What is the method of calculation according to the nature of the project?
The development tax is calculated differently depending on your project:

Construction project
To calculate the tax on a construction, the following data are taken into account:
- Number of m² of taxable area
- Value per m² fixed for the year (in 2025, it is €930)
- Municipal tax rate (variable per municipality and year)
- Departmental rate (variable by department and year).
The formula is:
(taxable area x flat rate x communal or intercommunal rate) + (taxable area x flat rate x departmental rate)
Example :
You would like to know the development tax to be paid for a construction of a 50 m² area close, covered, under a ceiling height greater than 1 m 80:
You multiply the number of m2 (50) by the value in m2 (€930):
50X €930 = 46,500
You multiply this result by the percentage decided by your municipality (communal rate) and by the percentage decided by your department (departmental rate).
If a communal rate of 3% and departmental rate of 2.5%, one obtains:
€46,500 X 3% = €1,395
€46,500 X 2.5% = €1,162
The sum of these two results gives the amount of the tax: €1,395 +€1,162= €2,557.
The fixed value of each m² of taxable area shall be reviewed annually on the basis ofCCI: titleContent . In 2025, it is €930.
FYI
A pergola, an arbor or a terrace are not taxable, because they are not closed and covered. On the other hand, a garden shed or a closed and covered veranda are taxable.
Development or installation project
The taxable value of your project is calculated as:
- or per unit (tent space, parking space, wind turbine...),
- or per m² of area (swimming pool, photovoltaic panel...).
The percentages (rates) for the municipality and the department are applied to this value.
The sum of these 2 results constitutes the amount of the tax.
Type of fitting-out or installation | Lump-sum value |
|---|---|
Tent pitch, caravan and mobile recreational residence on a campground or natural camping area | €3,000 by location |
Light-weight recreational dwelling | €10,000 by location |
Swimming pool | €262 per m² |
Wind turbine over 12 m | €3,000 by wind turbine |
Ground-mounted photovoltaic panel | €10 per m² of panel area |
Outdoor parking area | From €3,052 to €6,105 by location (as decided by the local authority) |
Example :
You would like to know the fitting-out fee to be paid for the fitting-out of 2 outdoor parking spaces:
If you take, for example, a €3,052 as a flat-rate value per place decided by the municipality
You multiply the number of parking spaces by €3,052 either:
€3,052 X 2 = €6,104
You must then multiply this result by the percentage decided by your municipality (communal rate) and by the percentage decided by your department (departmental rate).
If a communal rate of 3% and departmental rate of 2.5%, one obtains:
€6,104X 3% = €183
€6,104 X 2.5% = €152
The sum of these 2 results gives the amount of the tax: €183 +€152 = €335
Please note
Solar thermal panels, which produce heat, and parking areas for 2 wheels are not taxed.
Certain types of construction and fittings may be the subject of deductions or the following exemptions:
- Abatement of 50%on the flat-rate value

Construction project
To calculate the tax on a construction, the following data are taken into account:
- Number of m² of taxable area
- Value per m² fixed for the year (in 2025, it is €1,054)
- Municipal tax rate (variable per municipality and year)
- Departmental rate (variable by department and year)
- Regional rate (variable by department and by year).
The formula is:
(taxable area x flat-rate x communal or intercommunal rate) + (taxable area x flat-rate x departmental rate) +(taxable area x flat-rate x regional rate)
Example :
You would like to know the development tax to be paid for a construction of a 50 m² area, closed, covered, greater than 1.80 m:
You multiply the number of m² (50) by the value in m2 €1,054 :
50 X €1,054 = €52,700
You multiply this result by the percentage decided by your municipality (communal rate), then by the percentage decided by your department (departmental rate) and finally by the regional percentage (regional rate).
If, for example, a communal rate of 3% , a departmental rate of 2.5% and a regional 1% the result is
€52,700 X 3% (example of a communal rate) = €1,581
€52,700 X 2.5%(example of a departmental rate) = €1,317
€52,700 X 1%(example of a regional rate) = €527
You add up these 3 results to find out the amount of tax: €1,581 +€1,317 + €527 = €3,425
The flat-rate value of each m² of taxable area is reviewed annually on the basis of theCCI: titleContent . In 2025, it is €1,054.
