Property tax in Montpellier in 2026: the metropolitan share that pushes your bill up

1. A new metropolitan share on your property tax

Until 2025, the metropolitan authority of Montpellier levied an almost symbolic property tax share : a rate of 0,167 % on built property, which came to a few euros a year on the notice. The vote of 28 April 2026 changes the scale entirely : the rate is raised to 5,8 %, a multiplication by close to thirty-five.

The resolution concerns owners in the 31 municipalities that make up Montpellier Méditerranée Métropole, and not only the central city. Brought forward by the president of the metropolitan authority and mayor of Montpellier Michaël Delafosse, the measure aims, according to the executive, to keep the budget in balance and to fund public services against a background of falling State grants.

2. Why the bill climbs when the City has not moved

The distinction between the municipality and the metropolitan authority is at the heart of the Montpellier controversy of 2026. During the March 2026 municipal election campaign, Michaël Delafosse committed not to raise the property tax. The share voted by the City of Montpellier has indeed not moved. But the increase comes through another level : the metropolitan authority, whose council he chairs.

For the owner, this institutional subtlety changes nothing in the outcome : it is the same notice, and the total climbs. The new metropolitan share is added to the unchanged municipal share and to the other lines, including the national revaluation of the bases (+0,8 % in 2026).

3. How much the new share will cost you

The exact amount depends on the cadastral rental value of your home, which varies with its floor area, its comfort and its location. The orders of magnitude below, expressed as the annual extra cost linked to the metropolitan share alone, are anchored on real districts of Montpellier and on an average price of 3 434 €/m² across the municipality (DVF data, Immover single source, updated June 2026).

These values are indicative orders of magnitude, isolating the new metropolitan share. The real extra cost depends on the cadastral rental value specific to your property, which appears on your notice and which no generic calculation replaces.

5. How your property tax is worked out

The mechanism rests on three elements. First the cadastral rental value, which is the theoretical annual rent the property would produce. Then a 50 % allowance applied to that value to obtain the taxable base. Finally the rates voted by the authorities (municipality, metropolitan authority), applied to that base.

Two levers therefore make the amount vary : the rates, decided locally by each authority, and the base, revalued nationally every year (+0,8 % in 2026). In Montpellier, the municipality has not raised its rate ; it is the creation of a metropolitan share at 5,8 % that explains the rise in your 2026 notice.

6. An increase voted just after the municipal elections

The timing fuels the controversy. The campaign promise covered the municipal share, which has not risen ; the increase, for its part, took the form of a metropolitan share voted shortly after the election. Several mayors of municipalities in the metropolitan area voted against, among them Julien Miro, mayor of Castelnau-le-Lez, who had himself promised to cut the property tax by 20 % over the term.

The metropolitan executive justifies the measure by the need to fund public services against a background of reduced State grants to local authorities. The debate on the boundary between a municipal commitment and a metropolitan decision, when the same elected official chairs both, remains lively in Montpellier.

7. What impact on the value of your property?

Montpellier is one of the few large metropolitan areas whose property market did not correct after 2021 : prices there remain on an upward path, supported by one of the strongest rates of population growth in France and by the appeal of the way of life. This momentum sustains demand for housing, and therefore prices, whatever the level of property tax.

For an owner considering selling, the new metropolitan share is not a trigger. The value of a property in Montpellier depends first on its location, its floor area, its condition and its energy rating. A property tax increase can at most be a secondary argument in the negotiation, with an investor buyer comparing net yields between several cities.

If you want to place the value of your property within this market, the simplest route remains to start from the actual transactions of your district. That is the method we use to value a property in Montpellier.
