Infographics. Property tax: where are the biggest increases in Saône-et-Loire and neighboring departments?

Opening the mailbox, or the email inbox, may prove painful for some owners when they deliver the 2025 property tax amount by the end of September.

Already this year, all house and apartment owners will see their property tax increase by at least 1.7%. This corresponds to the national revaluation based on inflation of "cadastral rental values," that is, the theoretical rent generated by the property if it were rented out.

But beyond this increase for all, the local rates which apply to this basic value may have been increased (or reduced) by their municipality and/or their inter-municipality.

Between 2024 and 2025, 86.3% of municipalities have maintained their local direct tax rates for property tax on built properties; but in 4,386 municipalities (12.6% of the 34,797 French municipalities) it is increasing.

This is a municipal rate that has increased for 6.4% of the population, almost exclusively for residents of municipalities with fewer than 3,500 inhabitants: it is higher for 14.4% of residents of municipalities with between 500 and 3,500 inhabitants, compared to approximately 2% of residents of municipalities with between 10,000 and 100,000 inhabitants. The proportion of decreases is marginal (0.1% or 0.2%), as is that of increases of more than 10%.

Discover, municipality by municipality, the increases voted in 2025, and where the rate is the highest.

> Study on the rates voted in 2025 by municipalities and inter-municipalities (Public Finance Department).

• In the Rhône, Vindry-sur-Turdine, Tupin-et-Semons and Chevinay voted for increases of 2 points or more, i.e. +10%, +11.9% and +6.48% compared to 2024. The highest in the department but which nevertheless places them far from Rontalon (39.3%), Belmont-d'Azergues (37.83%) or Vaulx-en-Velin (37.5%) which occupy the departmental podium for the highest municipal rates.

• In the Loire, Lorette, Le Cergne and Saint-Appolinard voted for increases of 2 points or more (respectively 2.97, or +8% compared to 2024, +2.53, or +8.2 and 2 pts or +6.8%). This increase propels Lorette into the top 10 municipalities with the highest municipal rate. Unieux's 44.9% keeps it the department's record holder in terms of municipal rate despite a slight decrease voted. Saint-Étienne, with its significant increase last year (5.83 points; or +15%), remains second on the podium. La Ricamarie occupies ^3rd place but has not voted for an increase between 2024 and 2025.

• In Ain, Cleyzieu voted for a 5.29 point increase (+20.1% compared to 2024) for 2025, (far from the 9.5 point increase in Miribel between 2022 and 2023). Andert-et-Condon shows +4.04, Saint-Maurice-de-Gourdans: +3.32... But the municipalities remain far from the highest rates in Ain: Meillonnas and its 41.67%, Miribel at 39.50%, Bourg-en-Bresse at 39.07%...

• In the Jura, Saint-Claude (57.86%) still leads the podium for the highest municipal rates, ahead of Salins-les-Bains (57.26%). They are joined on the podium by Châtelneuf, which voted for an increase of 1.3 points in 2025. However, this is far from the highest increases in Syam (+4.05 pts, or +10%), Lemuy (3.5, +10%), Etival (2.42, +7%) and Choux (2.03, +5%).

• In Ain, the elected officials of Bouligneux are the only ones to have chosen to lower the municipal rate on built land: -3.58 points in 2025, just like, more modestly, those of Flaxieu (-0.59) and Haut Valromey.

• In the Loire, 5 municipalities have chosen to reduce their rates on built property, notably Neaux which lowered it by 3.41 points, representing a change of -11.6% for owners. Among the municipalities which voted for a more modest reduction, there are also Le Crozet (-0.92%), Saint-Paul-en-Jarez (-0.85), Unieux (-0.64) and Notre-Dame-de-Boisset (-0.53 points). However, Unieux remains at the top of the municipalities with the highest rate (44.9% in 2025)

• In the Rhône, only Oullins-Pierre Bénite and Grigny show a decrease (respectively -2.74 and -1% in 2025 compared to 2024). The second nevertheless remains in the top 20 municipalities with the highest rate.

• In Haute-Loire, 3 municipalities voted to lower rates, including Saint-Préjet-d'Allier with a reduction in its rate (among the highest nonetheless) of 4.22 points. Cronce also opted for a significant reduction of -3.68%; it is more modest in Langeac with 0.92%.

• In the Jura, 3 municipalities have chosen to reduce their built property tax rate, notably Taxenne, which has reduced it by 3 points, representing a change of -9%. Among the municipalities that voted for a more modest reduction are also Hautecour (-1.8%), and Ecrille (-1.75 points).

Urban communities and municipalities also apply a tax rate to built property. Thus, in 2025, 13.1% of the 1,249 municipal groups voted to increase the inter-municipal rate. So much so that the overall rate will increase in 24.5% of French municipalities, although in the vast majority of cases, the increase will be limited to less than two percentage points.

Thus in the Loire, even if their municipality has not raised its rate, taxpayers in the Communauté de communes du Pays entre Loire et Rhône will see their tax increase further: their inter-municipality has voted for an increase of 0.22 points for 2025.

In the Rhône, for owners in the Community of Communes of Vallons du Lyonnais (CCVL), this increase is even 0.64%

In Ain, the Miribel and Plateau Community of Communes voted for a 2% increase in 2025, while in Jura, the highest increase is only 0.14 points for the Grandvallière Community of Communes.
