Property tax in Antony in 2026: a moderate rate, and a rise that does not come from the town

1. A municipal rate of 27,09 %, close to the average of the Hauts-de-Seine

The property tax shown on your notice adds up several lines, but most of it comes from the municipal share. In Antony, it stands at 27,09 %. It is this rate, applied to the cadastral rental value of your property, that determines the bulk of your bill.

Compared with the rest of the department, this level is nothing extreme. The average of the Hauts-de-Seine is around 25 %, with a wide gap between the least taxed municipality (Marnes-la-Coquette, 13,86 %) and the most taxed (Le Plessis-Robinson, 37,06 %). Antony sits in the middle part of this ranking, a little above the average.

2. Why your rate jumped in 2021 without a decision of the town

This is the most widespread misunderstanding. Many owners saw, on their 2021 notice, the municipal property tax rate rise all at once, and concluded that their town hall had decided on an increase. In reality, the mechanism is purely national.

To offset the abolition of the residence tax on main residences, the State transferred to municipalities the share of property tax that previously went to the department. In practice, the former departmental rate was added to the municipal rate to form a new reference rate, higher on paper. This operation was neutral: on its own, it did not increase what you paid, it only changed how the rate is displayed.

The rate of 27,09 % you see today therefore includes this transferred departmental share. To judge the tax policy of the municipality itself, you need to look at the change in the rate voted by the municipal council, excluding the transfer: that is the subject of the following section.

3. How much you pay depending on your profile in Antony

These amounts cover the municipal share only, excluding the household waste collection tax. They illustrate a simple point: with a moderate rate, the bill remains reasonable given property values in Antony, where the average flat price approaches 5 096 €/m².

Four typical profiles in Antony

These orders of magnitude are given for guidance only: only the cadastral rental value shown on your notice allows an exact calculation. They assume a municipal share of 27,09 % applied to bases representative of each type of property.

5. A municipal rate held: the line of the municipality

This is the official position of the municipality, and it is consistent with the mechanism described above. A stable municipal rate does not mean a stable bill: property tax is the product of a rate, voted locally, and a base, the cadastral rental value, revalued every year by the State.

This revaluation follows the harmonised index of consumer prices. It has been strong in recent years: +7,1 % in 2023, +3,9 % in 2024, +1,7 % in 2025, then +0,8 % in 2026 according to INSEE, the French statistics institute. Applied to your base, this rise accumulates year after year, regardless of the municipal decision.

6. Antony after the municipal elections of March 2026

The March 2026 vote confirmed the outgoing majority. The list led by Jean-Yves Sénant won in the first round with just over 50 % of the votes, ahead of three other lists. A first-round victory gives the municipality clear continuity in its policy directions, including tax policy.

For an owner, what is at stake is not the 2026 rate, already known, but how it changes over the term now beginning. A municipal rate held until now does not prejudge the choices to come: they will depend on the state of municipal finances, the level of State grants and the investment choices of the re-elected team.

7. What effect on the value of your property?

Three effects are worth keeping in mind:

1. A limited weight for a main residence. For a household buying to live in the property, property tax remains marginal compared with the purchase price and the cost of the mortgage. A family flat of around 450 000 € bears a municipal share of around 1 380 € a year: real, but rarely decisive.

2. A yield criterion for the investor. A landlord reasons in terms of net yield: property tax eats into that yield, but the moderate rate of Antony works in their favour compared with more heavily taxed neighbouring municipalities.

3. Attractiveness driven by location. Antony benefits from its transport links (RER B, Orlyval, the scheduled arrival of line 18), the proximity of the Parc de Sceaux and a sought-after residential setting on the doorstep of Paris. It is this advantage, more than the level of property tax, that supports demand and prices.
