Property tax in Courbevoie in 2026: one of the eleven towns that raised their rate

1. What is the property tax rate in Courbevoie in 2026?

The structure of a Courbevoie notice is one of the lightest in the Île-de-France region, and that is already information in itself. Almost all of what you pay on the "built property" line goes to the municipality: the territorial public body levies no share on that base, and the household waste collection tax stays very low.

As everywhere in the Île-de-France region, regional special equipment taxes of a few tenths of a point are added, and appear at the bottom of your notice. They do not change the order of magnitude: in Courbevoie, the line that counts remains, by far, the municipal share.

The contrast with the household waste collection tax is worth noting. At 1,88 %, it is more than twice as low as the average of the Hauts-de-Seine (4,37 %). On a tax base of 4 000 €, the gap with that average represents around 100 € a year.

2. Why Courbevoie is one of the eleven towns that raised their rate

2026 is a year of almost general tax stability. In municipalities with more than 100 000 inhabitants, rates were massively carried over unchanged; only Montpellier (+10,7 %) and Nice, down 11,2 %, departed from the freeze. In the band of towns with more than 40 000 inhabitants, eleven rises out of 198 municipalities.

Three municipalities of the Hauts-de-Seine appear on that list, and the gap between them is instructive. Montrouge is raising its rate by 25 %, Clamart by 16,9 %, Courbevoie by 2,5 %. The pressure on the local finances of the department is the same; the budget response is not.

The 2026 budget of Courbevoie comes to 346,1 million euros, of which 266,7 million for operations and 79,4 million for investment. It was adopted at the municipal council meeting of 28 April 2026. The rate rise of 2,5 % is expected to bring in around 1,5 million euros of additional revenue, that is less than 0,5 % of the total budget.

The town points to two items to justify the move: around 29 million euros under the equalisation mechanisms, which redistribute revenue from the best-endowed municipalities towards the others, and 35,7 million of state levies weighing on its operating budget, to which a further million of pension contributions is added.

3. A rate raised, and still among the lowest in France

The gap has to be measured to be understood. In the Hauts-de-Seine, municipal rates range from around 13,9 % to 37,1 %: Courbevoie sits in the first sixth of the ranking, three points above the departmental floor.

That position comes down to the economic geography of the area. Courbevoie carries a large part of the La Défense business district, whose offices feed business taxation: the business property contribution, the contribution on added value, the tax on offices. A fabric of that density makes it possible to fund a municipal budget without drawing heavily on households.

The counterpart is called equalisation. A fiscally rich municipality contributes to the national and regional redistribution mechanisms, which the 29 million euros mentioned in the 2026 budget illustrate directly.

4. Simulator: what the 2026 rise costs you

The order of magnitude is quickly set. On a tax base of 4 000 €, the 2026 rise represents around 17 € a year. On the same base, the gap with the average of the Hauts-de-Seine exceeds 350 €. An owner in Courbevoie therefore keeps a tax advantage far greater than the cost of the rise just absorbed.

5. How much do you pay depending on your neighbourhood?

The amounts below are orders of magnitude built from typical profiles anchored on real neighbourhoods of Courbevoie and on the prices per m² drawn from our processing of DVF transactions, the French notarised sales database. They give an idea of the weight of the tax depending on the property, not a personalised calculation.

The spread between neighbourhoods is narrow for a town of this size. Bécon, at the top with 7 099 €/m², and Cœur de Ville, at the bottom with 6 078 €/m², are separated by a little more than 1 000 €/m², a ratio of 1,17. Courbevoie is a homogeneous market, with no neighbourhood left behind.

Measured against the value of the property, property tax in Courbevoie is light. A 3-room flat of 62 m² in Cœur de Ville is worth around 377 000 € and carries in the order of 940 € a year, that is 0,25 % of its value. In a provincial county town with a high municipal rate, the same ratio frequently exceeds 1 %.

6. Second home: the surcharge of 40 %

This is the point that the lightness of the property tax rate can obscure. While Courbevoie asks little of owner-occupiers, it makes full use of the lever open to municipalities in a high-demand area on second homes.

The mechanism is cumulative: a base rate of 14,52 %, then a surcharge of 40 % on the amount obtained. The residence tax on second homes accounted for around 3,65 million euros of municipal revenue in the last published financial year.

For an investor, the practical consequence is clear. In Courbevoie, a home left vacant or occupied a few weeks a year carries an annual cost well above that of a home let all year round, while property tax is identical in both cases. Local taxation there pushes towards letting rather than weighing on ownership.

7. Taxation or market: what really weighs?

This is the most useful perspective for an owner in Courbevoie. The market went from 7 553 €/m² in 2021 to 6 653 €/m² in 2026 (Immover processing, DVF data, the French notarised sales database), with a low point at 6 607 €/m² in 2024 and a stabilisation since. Volume remains solid, with around 915 transactions a year.

On a 3-room flat of 62 m², the fall of 900 €/m² since 2021 represents around 56 000 € of value. The property tax rise voted in 2026 costs, on the same property, less than 20 € a year. The two subjects do not play in the same category.

That does not make taxation negligible for all that. It comes into play at the moment of choice, when a buyer compares Courbevoie with a neighbouring municipality on an equal budget: at comparable property value, the gap in rate with Montrouge or Clamart, which have just raised theirs sharply, is a concrete argument in favour of Courbevoie.

The asking price nevertheless remains the first lever. To set it, a valuation based on the real transactions of your neighbourhood is the best basis. For other tax trajectories in the Paris region, see our analyses of property tax in Levallois-Perret and property tax in Asnières-sur-Seine.
