Property tax in Agen in 2026: a municipal rate in the order of 60,85 %, almost half of it inherited from the 2021 transfer of the departmental share, and a change of municipal majority in March 2026. Calculation, amounts by profile, simulator and impact on value.
Illustration : Property tax in Agen in 2026: the end of eighteen years of stability.
In Agen, the property tax tells a political story. For eighteen years, the administration of Jean Dionis du Séjour made it a marker: never raising the municipal rate, year after year, to the point of turning it into a campaign argument. That chapter closed in March 2026 with the election of Laurent Bruneau, leading a coalition of the left. The new council inherits a headline rate among the highest in France, largely a mechanical legacy of the transfer of the departmental share that took place in 2021. Yet the notice that Agen owners receive rises every year. Here is what you actually pay in Agen, why the municipal rate is so high without the town really having "raised" it, and what the new team can, or cannot, change.
The municipal rate of property tax on built property in Agen is in the order of 60,85 % (Source: DGFiP, 2023 financial year), one of the highest levels in France. But almost half of that rate corresponds to the former departmental share, transferred to municipalities in 2021 at no extra cost to the owner: the town itself has not raised its own component.
The property tax shown on your notice adds up several lines. In Agen, most of it comes from the municipal share, in the order of 60,85 %. That is the share the town votes, and the one that weighs most in your bill. On top of it comes a marginal inter-municipal share (around 1 %) paid to the Agglomération d'Agen, and small lines for aquatic environment management (GEMAPI) and the special facilities tax.
That municipal rate is among the highest in France, but the figure has to be read correctly. Until 2020, the share voted by the town was around 33 % (33,52 % in 2014, stable over the period). In 2021, the State abolished the residence tax on main homes and, to compensate, transferred to municipalities the share of the property tax that previously went to the department. In Agen, that departmental share, in the order of 27 points, was simply added to the municipal line. The headline total jumped, but the amount paid by the owner did not change as a result of that transfer.
The rate alone is not enough to compare two towns. A rate of 60 % applied to a modest rental value can produce a lower bill than a rate of 40 % on a high base. The bill depends on the product of rate × base, and the base, in Agen as elsewhere, dates for the most part from the 1970s.
The property tax is the product of a rate voted locally and a base, the cadastral rental value, set by the State then revalued each year. In Agen, the municipal rate has barely moved in its municipal component: it is the revaluation of the base that makes your notice vary from one year to the next.
The calculation starts from the cadastral rental value of your property, meant to represent a theoretical annual rent. A flat-rate allowance of 50 % is applied to obtain the taxable base, then that base is multiplied by the sum of the rates voted (municipality, inter-municipal authority, ancillary taxes).
Two levers move your bill: the rate, decided locally, and the base, revalued nationally. In Agen, the municipal component of the rate has been stable for a long time: the rise in your notice therefore comes almost entirely from the revaluation of the bases. To that is added, on a separate line, the household waste collection tax, calculated on the same base.
In Agen, the municipal share of the property tax most often falls between 500 € for a studio in the centre and 1 600 € for a family house, depending on the rental value of the property. Recent or renovated homes in Le Gravier and the residential districts carry the highest bills, with the household waste collection tax on top.
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 Agen districts. The prices per square metre quoted come from DVF data, the French database of notarised property sales, processed by Immover (2026).
| Property profile | District | Indicative price per m² | Municipal share of the property tax 2026 (order of magnitude) |
|---|---|---|---|
| 25 m² studio | Town centre (prefecture) | 1 960 €/m² | ~ 520 € |
| 65 m² 3-room flat | Le Gravier / banks of the Garonne | 1 730 €/m² | ~ 960 € |
| Renovated 80 m² apartment | Rodrigues | 1 210 €/m² | ~ 1 200 € |
| 105 m² house | Montanou | 1 830 €/m² | ~ 1 550 € |
These estimates cover the municipal share, excluding the household waste collection tax. They should be set against an Agen market with an average price of 1 751 €/m² for an apartment in 2026, a level that remains affordable for a prefecture town, and that is rising: the average apartment price went from around 1 530 €/m² in 2021 to nearly 1 790 €/m² in 2025 (DVF).
Enter the amount of the municipal share of your 2026 property tax (the first line of your notice). The simulator estimates the part that corresponds to the strictly municipal component (the one the council votes) and the part inherited from the 2021 transfer of the former departmental share, on which the town has no historical room for manoeuvre.
Because a stable rate does not mean a stable bill. The revaluation of cadastral rental values, decided nationally, applies everywhere: +0,8 % for 2026, after +1,7 % in 2025, +3,9 % in 2024 and +7,1 % in 2023 (INSEE). That is what pushes up the Agen notice, without the town having touched its component of the rate.
This is the most common misunderstanding. The property tax is the product of a rate, voted locally, and a base, the cadastral rental value, revalued each year by the State in line with inflation.
In recent years, that revaluation has been strong: +7,1 % in 2023, +3,9 % in 2024, +1,7 % in 2025, and +0,8 % for 2026 according to INSEE, that is around +18 % in total since 2020. Applied to your base, that increase compounds year after year, whatever rate the municipality votes. In Agen, where the municipal component of the rate has stayed stable, it is the main cause of the increase in the municipal share of your notice.
That mechanism explains the Agen paradox: an administration that long claimed not to raise taxes, and owners who nonetheless saw their notice rise. Both statements are accurate. The town held its line on the rate; the State revalued the base. The final amount adds the two together.
At the municipal elections of March 2026, Laurent Bruneau, leading a coalition of the left, was elected mayor of Agen with 39,05 % of the vote in the second round, ending eighteen years in office for Jean Dionis du Séjour. The new team inherits a municipal rate already among the highest in France: the room to raise it is narrow, and the room to cut it remains constrained by the funding of public services.
For eighteen years, stable taxation was a signature of the Dionis du Séjour administration, which had made it a repeated commitment of its terms: not raising municipal rates. On 22 March 2026, that continuity broke: Laurent Bruneau, candidate of the coalition of the left, won the second round with 39,05 % of the vote, ahead of the outgoing mayor (32,26 %). In the first round, on 15 March, Bruneau had already come first (34,50 % against 32,26 %).
For owners, the open question is one of trajectory. A municipal rate in the order of 60 % leaves little room for an increase without immediate political fallout; a cut, conversely, would run into the funding of municipal services and the weight of the departmental share absorbed since 2021, which the town controls only partly. The new team's first budget, voted in the spring, will set the tone.
A high property tax rate weighs at the margin on value, above all for buyers who watch annual running costs. In Agen, that effect remains secondary next to an affordable market heading upwards. The location, the condition and the energy rating of the property remain the first factors of value.
Three effects are worth keeping in mind.
1. A point of attention for the buyer. A buyer comparing Agen with a neighbouring municipality factors in the annual cost of ownership: a high property tax weighs in the equation, without being decisive next to the purchase price and the location.
2. A secondary factor at the scale of a budget. For a household buying its main home, the property tax remains marginal next to the purchase price and the cost of the loan. A 105 m² house in Montanou, at around 195 000 € at the area's average price, carries a municipal share in the order of 1 550 € a year: real, but rarely decisive.
3. A market that is rising. The average apartment price in Agen has gained close to 17 % in five years, driven by its status as a prefecture town, affordable prices and the appeal of the south-west of France.

The municipal rate of property tax on built property in Agen is in the order of 60,85 % (Source: DGFiP, the French public finances directorate, 2023 financial year, the latest detailed rate published), one of the highest in France for a prefecture town of this size. The inter-municipal share paid to the Agglomération d'Agen remains marginal, at around 1 %. Read that figure with care: almost half of the municipal rate corresponds to the former departmental share, transferred to municipalities in 2021 at no extra cost to the owner.
The headline municipal rate, around 60,85 %, is high because since 2021 it adds together the strictly municipal component (about 33,5 points, stable for a long time) and the former departmental share (about 27 points), transferred to municipalities to offset the abolition of the residence tax on main homes. The town has therefore not 'doubled' its rate: the 2021 transfer was neutral for the taxpayer. Nor does a high rate mechanically translate into a high bill: everything depends on the cadastral rental value of your property, which for the most part dates from the 1970s.
The strictly municipal component of the rate has not been raised for many years: the administration of Jean Dionis du Séjour had made stable municipal rates a commitment of its term. The rise in the headline municipal rate in 2021 comes solely from the transfer of the former departmental share, decided at national level. The increase in notices, for its part, is explained by the national revaluation of cadastral bases.
Laurent Bruneau, leading a coalition of the left, was elected mayor of Agen in the second round of the municipal elections, on 22 March 2026, with 39,05 % of the vote, ahead of the outgoing mayor Jean Dionis du Séjour (32,26 %). That election ends eighteen years in office for Jean Dionis du Séjour, in post since 2008. The new team's first budget, voted in the spring, will set out its tax policy.
Because cadastral rental values are revalued every year at national level, independently of the town's decisions. That revaluation follows the harmonised index of consumer prices: +7,1 % in 2023, +3,9 % in 2024, +1,7 % in 2025 and +0,8 % in 2026 according to INSEE, the French national statistics institute, that is around +18 % in total since 2020. In Agen, where the municipal component of the rate has stayed stable, it is the main cause of the rise in the municipal share of your notice.
It all depends on the cadastral rental value of the property. As an order of magnitude, on the municipal share alone, allow around 520 € for a studio in the town centre, around 960 € for a 3-room flat by the Garonne and in the order of 1 200 € for a renovated 80 m² apartment in Rodrigues. These amounts do not include the household waste collection tax. The average apartment price in Agen stands at 1 751 €/m² in 2026 (DVF, the French database of notarised property sales).
Only at the margin. A high cost of ownership can weigh on the decision of a buyer who watches annual running costs, but it remains secondary next to an affordable market that is heading upwards: the average apartment price has gained close to 17 % in five years in Agen. The location, the condition and the energy rating of the property remain the first determinants of its value.
