Building a swimming poolis a decision that many individuals dream of. Comfort, increased property value, family time… the advantages are numerous. But as soon as the project enters its concrete phase, one question often arises:what is the cost of taxes for a swimming pool?Whether it's ashell pool, a traditional pool, orabove-ground pools, thetaxationcan vary depending on several criteria.
Do you need to declare your swimming pool? When? What will be thecost of pool taxesto expect? Here is a complete guide to help you anticipate thecost of pool taxes, avoid mistakes, and declare your pool with complete 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 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 pool shellseven 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 preliminary 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 thethe tax authorities within 90 days afterdate of completion. 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 will have to pay is thedevelopment tax. It is due only once, the year following the declaration of your swimming pool. It applies to all swimming pools with a surface area greater than 10 m², whether covered or not.
Thetax calculationis 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 tax due from one region to another. In Ile-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 € for 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 assessed rental value of your property, which is the basis used by the property tax office to assess your local taxes.
The more your home is worth, the more you will pay. The amount of pool taxes will therefore vary according to:
- The size of the pool,
- Thetype of pool(in-ground, shell, above-ground),
- Theplace of residence(some municipalities apply higher rates than others).
Good news however: some municipalities offer atemporary exemption of two years, if the swimming pool is declared within90 daysof the completion of the works.
Council tax: special cases to be aware of
Theresidence taxhas been abolished for primary residences, but remains applicable tosecondary residences. In this case, as with property tax, the presence of a swimming pool increases therental cadastral value, and therefore theamount of the taxto be paid.
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 thecost of pool taxes, it is possible to act from the design phase. Here are some ideas:
- Choosing ashell poolunder10 m²(or mini-pools) : in this case, no declaration, nodevelopment tax, nor increase in property tax.
- Plan for an uncovered pool, as some pool shelters can be considered taxable structures.
