In Nantes, the property tax has risen by about 39 % since 2015, nearly twice as fast as inflation, while property prices have been falling. The path under Johanna Rolland, how the rate works, the amounts by profile and a calculator for the rise.
Illustration : Property tax in Nantes in 2026: ten years of rises on a falling market.
In Nantes, the property tax has seen no single hammer blow, but a long, steady climb. Since Johanna Rolland became mayor in 2014, the notice received by Nantes owners has risen almost every year, under the combined effect of rate increases voted locally and the national revaluation of the bases. The result: a liability that has grown about twice as fast as inflation, even as property prices in Nantes have been falling since 2021. Here is the path, the mechanism, and what it means profile by profile.
In Nantes, the property tax has risen continuously since 2014. For a typical 63 m² apartment, the liability went from about 882 € in 2015 to 1 226 € in 2024, close to +39 % under Johanna Rolland's terms of office. Source: property tax notices compiled locally.
Unlike Lyon, which raised its rate in one go in 2023, or Toulouse, which froze its own, Nantes stands out for a steady rise, year after year. That climb combines two movements: rate increases decided locally and the national revaluation of the cadastral bases, applied everywhere in France.
Johanna Rolland, elected mayor of Nantes in 2014 in the continuity of Jean-Marc Ayrault, has stood by this funding of public services through local taxation. The total amount collected by the town from the property tax on built property rose by about 58 % between 2013 and 2023, with, for example, a rise of the order of 6,7 % from 2022 to 2023 alone.
The amounts quoted are orders of magnitude drawn from notices for a given type of home. The amount of your own property tax depends on the cadastral rental value of your property, which appears on your notice and varies from one home to another.
Between 2015 and 2024, the Nantes property tax rose by about 39 %, while cumulative inflation reached about 19,7 % over the same period. The tax therefore climbed nearly twice as fast as the cost of living, that is of the order of 170 € more than a simple indexation on inflation for a bill of 1 226 €.
The gap with inflation is the central argument of the critics of Nantes tax policy. Had the property tax only followed the rise in consumer prices between 2015 and 2024, the 882 € liability of 2015 would have reached about 1 056 € in 2024. It actually stands at around 1 226 €, close to 170 € more.
That gap reflects a political choice: funding the town's public services and investment through taxation on owners, rather than through debt or lower spending. It is a direction the municipal majority stands by, but one that weighs directly on the budgets of owner households.
Comparing the property tax with inflation is the right reflex, but two causes must be told apart. The national revaluation of the bases follows inflation by construction (it is indexed on the price index). The gap beyond inflation therefore comes above all from rate rises voted locally. In Nantes it is that local component which explains why the bill has outrun simple indexation.
The municipal rate of property tax on built property in Nantes comes out at around 46 % in 2026, to which an inter-municipal share of about 6,4 % is added. That high level is partly due to the 2021 reform: the former departmental share was transferred to the municipalities, whose rate mechanically grew. Source: local tax data for 2026.
A municipal rate close to 46 % may come as a surprise. It is explained first by a national mechanism: in 2021, as part of the abolition of the residence tax on main homes, the departmental share of the property tax was transferred to the municipalities. The municipal rate displayed today therefore adds together the town's former share and the department's former share.
That reform did not, on its own, increase owners' liability: it merged two lines into one. But it makes the rate misleading to read if it is compared with figures from before 2021. What really weighs on the Nantes bill is the change in that rate since then, to which the national revaluation of the bases is added (+0,8 % in 2026).
The exact rates voted for 2026 appear on your property tax notice and in the data published by the DGFiP, the French public finances directorate. Should they differ from the orders of magnitude quoted here, the official notice prevails.
In Nantes, the annual property tax runs, as an order of magnitude, from a few hundred euros for a studio to more than 2 000 € for a family house. Those amounts have risen by about 39 % since 2015, under the effect of rate rises and the revaluation of the bases.
The orders of magnitude below apply to an annual property tax liability, all shares combined. They are anchored on real districts of Nantes and on an average price of 3 471 €/m² across the municipality (DVF data, the French notarised sales database, sole source Immover, updated June 2026). The last column isolates what the rise since 2015 has added to the bill.
| Typical profile | Annual property tax (order of magnitude) | Cumulative rise since 2015 |
|---|---|---|
| 25 m² studio, Chantenay | ~ 520 € | ~ 146 € |
| 63 m² 3-room flat, Saint-Donatien | ~ 1 226 € | ~ 344 € |
| 90 m² apartment, town centre | ~ 1 650 € | ~ 463 € |
| 110 m² house, Hauts-Pavés | ~ 2 050 € | ~ 575 € |
These figures are indicative orders of magnitude. The exact amount of your property tax depends on the cadastral rental value specific to your home, which appears on your notice and which no generic calculation can replace.
Enter the amount of your current property tax. The calculator estimates what you would have paid at the 2015 level and puts a figure on the part of your liability that comes from the cumulative rise since then (about +39 % over the period, rates and bases combined).
A Nantes particularity: the property tax has kept rising while property prices were falling. The average price went from about 3 900 €/m² in 2021 to 3 471 €/m² in 2026, about -11 % over five years. For the owner, that is a squeeze: a rising tax burden, a falling property value.
After a decade of surging prices driven by the city's appeal and its fast link to Paris, the Nantes market corrected as loan rates rose: the average price per m² fell by about 11 % between 2021 and 2026, and by about a further 1,2 % over the last twelve months (DVF data, sole source Immover).
That double dynamic deserves to be set out clearly for an owner. The property tax, which depends on the rates voted and on the cadastral rental value, does not follow the market price: it can climb when prices fall. The subject is a sensitive one for owners who see their annual charge rise while the resale value of their property slips.
The level of the property tax plays at the margin on the price per m² in Nantes. The value of a property depends first on its location, its floor area, its condition and its energy rating. But on a market already in decline, a high tax burden can become a bargaining argument for the buyer.
Nantes remains an attractive metropolitan area, and the price correction since 2021 does not call that underlying appeal into question. The property tax is not a buyer's first criterion: they look first at the district, the floor area, the condition and the energy rating of the home.
That said, in a market where the buyer has regained the upper hand, the amount of the property tax enters the calculation of the cost of holding a property. An investor buyer, comparing net yields between several cities, factors that charge in. It is one bargaining argument among others, alongside the energy rating and the condition of the property.
If you want to place the value of your property in this shifting market, the simplest approach remains to start from the actual transactions in your district. That is the method we use to value a property in Nantes.
For a typical 63 m² apartment, the Nantes property tax went from about 882 € in 2015 to 1 226 € in 2024, close to +39 % under Johanna Rolland's terms of office. Over the same period, inflation ran at about 19,7 %: the tax therefore climbed nearly twice as fast as the cost of living. The total amount collected by the town from tax on built property rose by about 58 % between 2013 and 2023.
The municipal rate of the property tax on built property in Nantes comes out at around 46 % in 2026, to which an inter-municipal share of about 6,4 % is added. That high level is partly due to the 2021 reform: the former departmental share of the property tax was transferred to the municipalities, whose displayed rate mechanically grew. The exact rates appear on your notice and in the data of the DGFiP, the French public finances directorate.
Because on top of the national revaluation of the bases, which follows inflation by construction, come the rate rises voted locally. In Nantes it is that local component which explains why the bill has outrun simple indexation on prices. Between 2015 and 2024, the tax rose by about 39 % against 19,7 % of inflation, that is of the order of 170 € more than indexation for a bill of 1 226 €.
In 2021, as part of the abolition of the residence tax on main homes, the departmental share of the property tax was transferred to the municipalities. The municipal rate displayed today therefore adds together the town's former share and the department's former share. That reform did not, on its own, increase the liability: it merged two lines into one, which makes comparison with figures from before 2021 misleading.
As orders of magnitude, all shares combined: about 520 € for a studio in Chantenay, 1 226 € for a 3-room flat in Saint-Donatien, 1 650 € for an apartment in the town centre, 2 050 € for a house in Hauts-Pavés. On those amounts, the rise since 2015 has added of the order of 150 to 575 €. The exact amount depends on the cadastral rental value specific to your home, which appears on your notice.
The 2026 property tax notice is sent by the DGFiP, the French public finances directorate, between the end of August and the beginning of October 2026, and made available on impots.gouv.fr. The payment deadline is generally set at 15 October for taxpayers paying by monthly instalments and 20 October for direct payment.
The direct impact is limited, but the context matters. The average price in Nantes fell by about 11 % between 2021 and 2026, to 3 471 €/m². On a market already in decline, a high tax burden can become a bargaining argument for the buyer, above all an investor comparing net yields between several cities. The value of a property nonetheless depends first on its location, its floor area, its condition and its energy rating.
If you believe your property tax is wrong, for example because the taxable base does not match your home, you can file a claim through your personal account on impots.gouv.fr, in the Réclamations section, or with the tax office covering your property. The appeal period runs until 31 December of the year following that in which the notice was issued.
