Property tax in Aix-en-Provence in 2026: a rate frozen since 2021, a bill that keeps rising

1. A municipal rate of 32,69 %, frozen since 2021

The property tax shown on your notice adds up several lines. In Aix-en-Provence, the bulk lies in the municipal share, set at 32,69 %, to which an inter-municipal share of 2,59 % is added. It is the municipal share that the city council votes each year, and it determines most of your bill.

One particularity explains the current level of the rate. In 2021, the abolition of the taxe d'habitation (residence tax, now abolished on main homes) triggered the transfer of the departmental share of the property tax to the municipalities. The departmental rate was added to the municipal rate to form a new reference rate, without your bill changing as a result. Since this transfer, Aix-en-Provence has chosen not to alter its rate again.

2. How your property tax is calculated in Aix

Your bill is calculated by multiplying the cadastral rental value of your property, reduced by a 50 % allowance, by the voted rates. The rental value is an administrative estimate of the theoretical annual rent your home would produce. It is the parameter that moves each year, even when the rate does not move.

This revaluation of the bases is national : it applies everywhere, in the same way, regardless of the municipality's decisions. It follows the harmonised index of consumer prices recorded in November of the previous year. Over recent years it has been especially strong : +7,1 % in 2023, +3,9 % in 2024, +1,7 % in 2025, and +0,8 % in 2026 according to INSEE.

3. How much you pay by profile

The property tax is not calculated on the price at which you would sell your property, but on its cadastral rental value. Two homes of comparable size can therefore carry different bills depending on their administrative classification. Here are four typical profiles anchored on real districts of Aix, as orders of magnitude on the municipal share alone.

These orders of magnitude cover the municipal share alone, excluding the household waste collection tax (TEOM) and the inter-municipal share. They should be weighed against an Aix market among the most expensive in France outside the capital and the Côte d'Azur, with an average price of around 5 038 €/m². Our page price per m² in Aix-en-Provence details these levels district by district.

5. Why a moderate rate does not make a small property tax

Compared with other cities in the Journal, Aix sits in a low range : 32,69 %, against 43,44 % in Tours or markedly higher levels in Marseille, in the same metropolitan area. A moderate rate might suggest light taxation. That is not quite the case.

Two mechanisms explain it. First, the cadastral rental value of a sought-after Aix property stays high, which inflates the base even at a contained rate. Second, the perceived weight of the tax often relates to the value of the property : at an average of 5 038 €/m², Aix real estate is expensive to acquire, and the property tax adds to an already high cost of use. The moderation of the rate is real, but it does not make the bill disappear.

6. Stability renewed at the ballot box, a metropolitan area under supervision

The political timeline sheds light on the choice to freeze. Mayor since 2021, after the resignation of her mother Maryse Joissains-Masini, Sophie Joissains held a stable municipal rate over the whole term. Her re-election in March 2026, with the 'Passionnément Aixois' list, was won on a pledge of fiscal stability reaffirmed during the campaign.

But municipal taxation is not decided in isolation. Aix belongs to the Aix-Marseille-Provence metropolitan area, whose finances have been placed under watch. For 2026, the prefect of Bouches-du-Rhône settled a metropolitan budget with no tax rise, at the cost of savings spread across the municipalities. Aix is expected to lose in the order of 1,3 million euros in grants, which weighs on the city's room for manoeuvre, even at a frozen rate.

7. What impact on the value of your property?

Three effects are worth keeping in mind.

1. A secondary factor for a main home. For a buyer coming to live in Aix, the property tax stays marginal against the purchase price and the cost of credit. An 85 m² flat in the heart of the Mazarin district, at more than 400 000 € at the average Aix price, carries a municipal share of around 1 550 € a year : real, but rarely decisive in the decision.

2. A point of vigilance for investors. On an expensive market, rental yield is already tight ; the property tax eats into part of it. For a landlord, it is a parameter to factor into the calculation, even if the Aix rate stays more contained than that of neighbouring cities.

3. Appeal driven by the city, not by taxation. Aix benefits from its heritage, its university, its economic role in the metropolitan area and a durably sought-after market. It is this foundation, more than a level of property tax taken as a given of the city, that supports demand and the value of properties.
