Choosing the right size pool can help you enjoy the pleasures of swimming without adding to your tax bill. So, what size pool is ideal for avoiding tax? Follow the guide, we'll explain everything!

Tax regulations for swimming pools in France

Definition of a taxable swimming pool

So let's get serious: what makes a swimming pool taxable or not? The rule is simple but daunting: in France, a swimming pool is taxable if it is considered a "construction". This means that it must be permanently fixed to the ground. In other words, if you can dismantle it without damaging it, it is not taxable.

Taxability criteria

In-ground pools These are generally taxable because they are fixed and permanent.
Above-ground pools The good news is that these pools often escape tax, especially if they can be dismantled.

Distinction between swimming pools

The in-ground or semi-in-ground pools are considered to be permanent structures and are therefore taxable.
The removable above-ground pools (think of swimming pools in kit form that are dismantled in winter) are not generally subject to property tax.

Basically, if your pool is in-ground, get ready to see your property tax go up. But if you opt for an above-ground pool that you put away in the autumn, you can dive in without any tax worries. Make the right choice so you can enjoy your summer without your local council adding to your bill!

Tax and legal standards

Let's get down to business boring serious matters: the tax and legal regulations governing swimming pools. Don't panic, I'll explain it all simply and clearly so that you're up to speed before you start.

Current legislation

In France, building a swimming pool is subject to certain regulations. If your pool is more than 10 m² but less than 100 m², you need to obtain a preliminary works declaration. If it exceeds 100 m², you will need planning permission.


Role of the land registry

  • Le land registerIt's a bit like the Big Brother of swimming pools. All in-ground swimming pools must be declared to the land registry. This register enables the tax authorities to know exactly which properties need to be taxed.
  • Mandatory declaration If you are installing a swimming pool, you have 90 days after completion of the work to declare it to the tax authorities. This can be done by filling in a specific form, Cerfa no. 6704 IL.

These standards may seem a bit daunting, but they are essential to avoid unpleasant surprises. It's best to be in order from the outset to avoid fines or unexpected property tax increases. Before you put your toes in the water, make sure you know these rules and follow all the administrative steps.

Different pool sizes and their tax impact

Pools under 10 m² in size

If you're looking to install a swimming pool without worrying about tax, the ideal solution is to opt for a mini-pool of less than 10 m². These little marvels let you enjoy the pleasures of swimming without adding to your property tax. Here's why these pools are an excellent choice:

Tax exemption: swimming pools of less than 10 m² are not subject to property tax. You read that right, zero additional tax! Perfect for small budgets or small gardens.

Mini pools are quick and easy to install, and often require no planning permission. It's a smart choice that lets you swim without worrying about paying more tax. So why not consider this practical and economical option?

Swimming pools from 10 to 100 m²

When it comes to swimming pools between 10 and 100 m², we're talking about the big boys. These pools offer plenty of space for swimming and relaxing, but beware: they are subject to taxation. Here's what you need to know to avoid tax surprises.

  • Taxation and calculation of property tax

Pools of this size must be declared and will be included in the calculation of property tax. This tax is based on the cadastral rental value, which is then multiplied by the tax rates voted by the local authorities.

How does it work? For example, if the rental value of your swimming pool is €1,500, and the local tax rate is 20 %, your annual property tax will be €300.

  • Some simulations

25 m² rectangular swimming pool If you install a beautiful 25 m² rectangular swimming pool in your garden. It's an excellent compromise between space and cost. If the rental value is estimated at €2,000 with a tax rate of 25 %, you will pay €500 a year in tax.


50 m² family pool For a larger pool, say 50 m², the tax impact will be more significant. If the rental value is €4,000 and the tax rate is 20 %, you can expect to pay €800 a year.

Pools over 100 m² in size For those who dream big, swimming pools over 100 m² are the ultimate in luxury and comfort. But beware, these large pools come with a considerable tax impact. Here's what you need to know before plunging into such a project:

  • Swimming pools larger than 100 m² are subject to property tax and can also significantly increase the cadastral rental value of your property, leading to a substantial increase in your local taxes.
  • How does this work? For example, a large 120 m² swimming pool might have a rental value of €8,000. With a tax rate of 25 %, you would end up paying €2,000 a year in tax.

These examples show that the size of your pool has a direct impact on your tax bill. It's a good idea to plan ahead and understand these tax implications before embarking on the installation of a pool of this size. By choosing wisely, you can enjoy a beautiful pool while keeping your finances under control.

Strategies for optimising the size of your pool

Choosing the type of pool

Now let's talk strategy! If you want to avoid paying extra tax while enjoying a swimming pool, the choice of pool type is crucial. Here are a few options and tips to help you make the best decision.

Advantages of above-ground pools

Above-ground pools have a major tax advantage: they are generally tax-free, especially if they can be dismantled. You can install them easily and dismantle them at the end of the season, so you don't have to pay property tax.

Optimising space

Do you dream of a swimming pool but don't want to blow your budget on tax? Don't worry, there are tricks you can use to make the most of your space and choose the right pool without bleeding your wallet. Here are a few clever tips for maximising your space while remaining tax-efficient.

Tips for maximising the use of space
  • Form and design Choose a pool shape that blends in well with your garden. Rectangular or L-shaped pools can make efficient use of the space available without exceeding tax thresholds.
  • Intelligent installation Place your pool near the corners or edges of your garden to maximise usable space. Avoid central areas to save space for other activities or landscaping.
  • Accessories and fittings : uses modular decking and landscaping to optimise the space around the pool. Narrow coping stones and integrated storage solutions can work wonders.

These tips will help you enjoy a beautiful pool without blowing your tax budget. Optimising space is the key to reconciling aquatic pleasure with tax savings. Think carefully about the layout of your garden and make the smartest choices 😉

Practical advice for future pool owners

Administrative steps to follow

Before you set about installing your dream pool, there are a few administrative steps you should not overlook. Following these steps will enable you to avoid future problems with the local authorities and enjoy your pool with peace of mind. Here are the key steps to follow:

  • Declaration of work

If your swimming pool is between 10 and 100 m² in size, you will need to submit a preliminary works declaration. It's as simple as filling in Cerfa form 1370307 and handing it in at the town hall. You don't need planning permission, but it is a compulsory formality. Planning permission is required for swimming pools larger than 100 m². You'll need to fill in Cerfa form no. 1340607 and provide detailed plans. Don't forget to allow time for the application to be processed, as it can take several months.

  • Interaction with the tax authorities

Once your pool is finished, you have 90 days to declare it to the tax authorities. To do this, you need to fill in Cerfa form n°6704 IL, which updates the cadastral rental value of your property. This declaration is essential for your pool to be registered and to avoid penalties.

I advise you to keep a copy of all documents and exchanges with the authorities. This may prove useful in the event of a dispute or future audit.

  • Compliance with local regulations

Find out about local planning regulations. Some communes impose specific rules on distances from neighbours, the height of fences and the installation of safety devices (barriers, alarms).

Tip A phone call to the town hall or a visit to the town planning department can save you time and avoid costly mistakes.

A square project requires a little effort, but it will allow you to enjoy your new swimming pool with complete peace of mind!
