But as soon as the project enters its concrete phase, one question often comes up: what is the tax cost of a swimming pool? Whether it's a shell pooltraditional pools or above-ground poolsthe taxation can vary according to a number of criteria.
Do I have to declare my pool? When do I do it? How much will swimming pool taxes taxes? Here's a complete guide to help you anticipate the pool tax costsavoid mistakes and declare your pool with peace of mind.
Does a swimming pool have to be declared to the tax authorities?
A question of pool type and ground fixing
The main criterion for determining whether a swimming pool should be declared is whether it is anchored to the ground and its permanent nature. A permanently installed swimming pool, whether in the ground or on a slab, is considered to be a built outbuilding and is therefore included in calculation of local taxes.
This applies to all in-ground pools and the majority of shell poolseven if delivered as a single unit. On the other hand above-ground pools are often exempt, provided they can be removed without damage.
Prior declaration or building permit: what steps to take?
In France, the majority of swimming pools are subject to a prior declaration declaration. If the pool exceeds 10 m² and cannot be dismantled, the declaration becomes compulsory. In certain cases, notably for large pools or when masonry work is masonry work are planned, a building permit is required.
Once the pool has been installed, you must inform thetax authorities within 90 days aftercompletion of the work. This deadline is a condition for access to a possible temporary exemption from property tax.
Taxes after pool installation
Development tax: an immediate contribution
One of the first taxes you'll have to pay is the development tax. This is payable only once, in the year following the declaration of your pool. It applies to all pools with a surface area greater than 10 m², whether covered or not.
Visit tax calculation is based on a simple formula:
Taxable area (in m²) × flat-rate value (233 €/m² in 2025) × (municipal rate + departmental rate)
Each commune and department sets its own rates. Thus, the amount of the tax from one region to another. In Île-de-Francefor example, the flat-rate value is slightly higher (262 €/m² in 2025).
A concrete example:
- For a 30 m² swimming pool located in a commune where the municipal rate is 3% and the departmental rate is 1.5%:
- 30 × 233 = 6 990 €
- 6 990 × 4,5 % = 314,55 €
- You will therefore pay approximately 315 € from development taxin two instalments.
Property tax: a recurring local tax
A swimming pool adds value to your property, which has a direct impact on your property tax. It increases the cadastral rental value of your property, which is the basis used by the property tax office to assess your local taxes.
The more your home increases in value, the more you'll pay. Visit amount of pool taxes will vary according to :
- The basin size,
- The type of pool (in-ground, shell, above-ground),
- Le place of residence (some communes apply higher rates than others).
The good news is that some municipalities offer temporary exemption for two yearsif the pool is declared within 90 days following completion of the work.
Council tax: special cases to be aware of
The taxe d'habitation has been abolished for principal residences, but remains applicable to secondary residences. In this case, as with property tax, the presence of a swimming pool increases the cadastral rental valueand therefore the amount of tax tax payable.
Be careful if you own a vacation home with a swimming pool: the tax bill could rise.
Can these taxes be reduced or avoided?
Adapting your project to optimize taxation
To limit the the cost of pool taxesIt's possible to take action right from the design phase. Here are a few suggestions:
- Choosing a shell pool from less than 10 m² in size (or mini-pools): in this case, no declaration, no development taxand no increase in property tax.
- Plan for an uncovered pool, as some pool shelters can be considered taxable structures.
