Property tax in Rennes in 2026: 47,7 %, one of the highest rates

1. A rate among the highest of the large cities

The property tax shown on your notice adds up several lines. In Rennes, the bulk of it lies in the municipal share, set at 45,66 %. That is the one voted by the city council, and the one that determines most of your liability. To it is added a modest inter-municipal share paid to Rennes Métropole, of the order of 1,73 %, also stable from one year to the next.

Set against other large cities, that level is high. Where Toulon stays below 40 % for its municipal share, Rennes exceeds 45 %, and its overall rate approaches 48 %. For an owner, that means that at a comparable rental value, the bill in Rennes is appreciably heavier than in a city with a low rate.

2. How your property tax is calculated in Rennes

The calculation rests on a mechanism that is simple in appearance. It starts from the cadastral rental value of your property, meant to represent a theoretical annual rent. A flat allowance of 50 % is applied to it to obtain the taxable base, then that base is multiplied by the sum of the rates voted (municipality, inter-municipal authority).

Two levers therefore move your liability: the rate, decided locally, and the base, revalued nationally. In Rennes, the first has been stable for several years. It is therefore the second, the revaluation of the bases, that almost single-handedly explains the rise in your notice from one year to the next.

3. How much you pay depending on your property

The exact amount depends on the rental value of your home, and therefore on its floor area, its address and its condition. Here are indicative orders of magnitude for the municipal share alone, for profiles representative of the districts of Rennes.

These estimates cover the municipal share, excluding the household waste collection tax. They should be read against a dynamic market in Rennes, with an average apartment price of around 3 755 €/m² in 2026 according to DVF data and the Immover single source. Unlike cities with low rates, in Rennes the weight of local taxation is added to an already high purchase price.

5. Why your notice climbs when the rate is stable

This is the most frequent misunderstanding. A stable rate does not mean a stable liability. The property tax is the product of a rate (voted locally) and of a base (the cadastral rental value, revalued every year by the State).

That revaluation follows the harmonised index of consumer prices. Over recent years it has been particularly strong: +7,1 % in 2023, +3,9 % in 2024, +1,7 % in 2025. For 2026, it falls back to +0,8 % according to INSEE, the French national statistics institute. Applied to your base, that increase adds up year after year, regardless of the stability of the municipal rate.

6. A high rate, the counterpart of a metropolitan area in high demand

In Rennes, the high rate is not an accident: it reflects a sustained level of services and investment, in a city whose population and employment are growing. A second metro line brought into service, a dense transport network, public facilities: that offer has a cost, funded in part by local taxation.

The political context is one of continuity. Nathalie Appéré (Parti socialiste), mayor since 2014 and president of Rennes Métropole, was re-elected on 22 March 2026 for a third term, with 43,78 % of the vote in the second round, ahead of Charles Compagnon (Horizons) and Marie Mesmeur (La France insoumise). That continuity makes an abrupt swing in the rate, in either direction, unlikely.

For an owner, the issue is therefore not a surprise rise in the rate, which is already known and stable, but the fact that this rate starts from a high level. The bill will keep rising at the pace of the bases, on a rate base that remains one of the heaviest of the large cities.

7. Second homes: the surcharge of 60 %

The residence tax has disappeared for main homes, but it remains due on second homes. In municipalities classified as under housing pressure, the law allows a surcharge of between 5 % and 60 %. Rennes applies the ceiling of 60 %, like Paris, Lyon, Bordeaux, Nice or Marseille.

In practice, the owner of a pied-à-terre in Rennes pays two local taxes: the property tax, at the city's high rate, and the residence tax on second homes, surcharged by 60 %. That combination is meant to discourage the holding back of homes in a market where demand for main residences is strong.

8. What impact on the value of your property?

Three effects are worth keeping in mind.

1. A relative brake for investors. With an overall rate close to 48 %, the property tax eats into the net rental yield more than elsewhere. On a property bought at around 3 755 €/m², it has to enter the profitability calculation from the outset, or the yield will be overestimated.

2. A secondary factor for a main home. For a buyer moving in, the property tax remains marginal compared with the purchase price and the cost of the loan. An apartment of 85 m² in the Thabor, at around 365 000 € at district prices, carries a municipal share of the order of 1 520 € a year: real, but rarely decisive.

3. An appeal that absorbs the cost. A student city, a hub of service and technology employment, well connected to Paris, Rennes keeps solid demand that supports prices despite the taxation.
