In France, owning a second home exposes one to a layering of taxes that the primary residence has not been subject to since 2023. The housing tax remains, with an increase in tight zones, capital gains tax upon resale, and wealth tax for the highest assets: the annual tax bill often exceeds several thousand euros for a property of average value. Understanding each layer of this taxation allows for anticipating the real costs before acquiring or during the ownership of the property.
Single tax on vacant housing in 2027: an unknown tax risk
Articles dedicated to taxes on second homes focus on existing taxes. However, an upcoming change deserves the attention of property owners: a single tax on vacant housing will come into effect in 2027.

This system replaces the coexistence of several local and national mechanisms with a unified framework. In tight zones, it will automatically apply after at least one year of vacancy as of January 1 of the tax year.
- The rate will reach 17% of the cadastral rental value in the first year, then 34% in subsequent years.
- Municipalities may go up to 30% in the first year and 60% thereafter, under certain conditions.
- Second homes left empty or very sparsely furnished will be directly affected, as the tax authorities could reclassify the property as vacant housing.
For owners who occupy their property only a few weeks a year without sufficiently furnishing it, the line between second home and vacant housing becomes a concrete tax issue. The risk of reclassification could generate a heavier tax burden than the housing tax on the second home itself.

Before investing in a second property, it is useful to know everything about the taxation of second homes to assess the impact of these regulatory changes on the overall holding budget.
Housing tax and increase in tight zones: the real amounts
Since 2023, only second homes are subject to the housing tax. The amount depends on the cadastral rental value of the property, multiplied by the rates voted by the municipality and the intermunicipality.
The 2024 finance law has expanded the scope of the increase to more than 3,700 municipalities classified as tight zones. In these areas, local authorities can vote for a surcharge of up to 60% of the base amount. For a property with a housing tax of 1,500 euros, the increase can thus add up to an additional 900 euros.
Some situations grant a reduction or exemption. People forced to reside in a different municipality from that of their property for professional reasons may, under certain conditions, obtain a relief. The available data do not allow for an exhaustive list of exemption cases, as they vary according to municipal deliberations.
Occupation declaration: an obligation not to be neglected
Each owner must make an occupation declaration to the tax authorities before July 1 in case of a change in situation. Failure to declare or an erroneous declaration exposes one to a flat fine. The tax authorities use this declaration to determine whether the property falls under the housing tax on second homes, the tax on vacant housing, or neither.
Capital gains tax upon resale: the schedule of deductions
The resale of a second home triggers taxation on the capital gain at a global rate of 36.2% (combined income tax and social contributions). Unlike the primary residence, there is no automatic exemption.
The deduction mechanism operates on two parallel schedules. For income tax, total exemption occurs after 22 years of ownership. For social contributions, one must wait 30 years. Between the sixth and twenty-second year, a progressive deduction reduces the taxable base each year.
A point often underestimated: the acquisition price retained by the tax authorities can be increased by actual acquisition costs (or a flat rate of 7.5%) and the cost of works carried out (or a flat rate of 15% after five years of ownership). These increases mechanically reduce the taxable capital gain. Keeping invoices for works throughout the entire duration of ownership is a precaution that can represent several thousand euros in tax savings at the time of sale.
IFI and second home: the absence of deduction that changes the game
Taxpayers whose net real estate assets exceed 1.3 million euros are liable for the real estate wealth tax. The primary residence benefits from a 30% deduction on its market value for the calculation of the IFI. The second home, on the other hand, is included at its full value.
This difference in treatment weighs heavily in the final calculation. A secondary property valued at 400,000 euros will be counted for 400,000 euros, whereas a primary residence of the same value would only count for 280,000 euros. For assets close to the threshold, owning a second home can be enough to trigger liability for the IFI.
Arbitration between holding and selling
The accumulation of the increased housing tax, property tax, IFI, and latent taxation on capital gains creates an annual holding cost that sometimes exceeds the potential rental yield of the property. Field reports vary on this point: some owners prefer to keep a family property despite negative profitability, while others choose to sell after 22 years to benefit from the capital gains exemption for income tax.
The taxation of second homes functions as a layering where each layer (housing tax, property tax, IFI, capital gains) obeys its own rules of calculation and deduction. The introduction of the single tax on vacant housing in 2027 adds an additional variable for under-occupied properties. Before any acquisition or decision to retain, a precise estimate incorporating all these levies remains the only reliable method to assess the real cost of ownership.
