A parent passes away, and three heirs find themselves co-owners of an apartment without having asked for it. The first income tax return that follows immediately raises a concrete issue: who declares what, on which form, and for what share? The declaration of a property in joint ownership follows specific tax rules, and errors in the distribution among co-owners can trigger follow-ups from the administration.
Property tax in joint ownership: one notice, several debtors
Contrary to what many co-owners assume upon receiving the mail, the property tax is not individualized by co-owner. The notice is issued in the name of all co-owners when there are two or three. Beyond that, it is issued in the name of the person holding the largest share, followed by the mention “and others” or “and co-owners,” according to data published by Service-Public.fr.
Each co-owner must then contribute according to their rights. There is no tax solidarity among them in this regard: if one does not pay their share, the administration cannot demand the total from another. Thus, there is a single notice but an obligation for internal distribution, which requires a minimum of organization among the parties.
To find all the steps to follow on Foncier.net, the dedicated sheet details the forms and deadlines applicable at each stage of the declaration.
Severance and joint ownership: do not confuse the two regimes
When a property is held by a usufructuary and one or more bare owners, the property tax is established in the name of the usufructuary. They are normally the one liable for it. This distinction is important in inheritances with reserved usufruct, common when a surviving spouse retains enjoyment of the property.
Families regularly confuse their situation: joint ownership among heirs and severance do not follow the same tax rules. Checking the title of ownership or the notarial certificate allows one to understand the framework before filling out anything.
Rental income in joint ownership: declare your share either under the real regime or the micro regime
When the jointly owned property is rented unfurnished, each co-owner declares their share of the rental income on their own income tax return. The choice of tax regime (micro-property or real) is made individually, but the eligibility conditions must be met for each co-owner.
Under the micro-property regime, a flat-rate deduction on the rents received is available. Under the real regime, actual expenses (work, loan interest, insurance, property tax) are deducted. The decision depends on the amount of deductible expenses compared to rental income.
Common pitfalls on form 2044
Form 2044 (declaration of rental income under the real regime) must only mention the portion of rents and expenses corresponding to the co-owner’s share. One does not declare the total income of the property and then divide it: each co-owner fills out their own line with their own share.
The most frequent errors:
- Declaring the total rents received while only holding a fraction of the property, which artificially inflates the taxable income
- Forgetting to report deductible expenses in proportion to their share, particularly the works voted on in the co-owners’ assembly
- Not keeping proof of distribution among co-owners, complicating any subsequent verification by the administration
Declaration of occupation and “Manage my properties” space
Since the establishment of the “Manage my properties” space on impots.gouv.fr, each owner must declare the occupation of their properties. In joint ownership, this obligation concerns each co-owner for their share.
A practical point to know: an error regarding the characteristics of the property or the persistence of a sold property does not block the declaration of occupation. The administration provides a separate reporting or correction procedure. Responses vary on this point according to departments, but the platform generally allows reporting the anomaly without preventing the validation of the form.
When one co-owner occupies the property and others do not
If one of the co-owners lives in the property while the others do not, the declaration of occupation differs for each. The occupant declares the property as their primary residence. The others declare it as a property not personally occupied.
This configuration has a direct impact on any exemptions or increases in housing tax on secondary residences, depending on the municipality. It is advisable to check the cadastral situation of the property before validating the declaration.
Joint ownership and IFI: the discount as a tax lever
For assets subject to the Wealth Tax on Real Estate, a property held in joint ownership may be subject to a discount. The logic is simple: a property in joint ownership is less liquid than a property held in full ownership, as its sale requires the agreement of the co-owners or a judicial decision.
Each co-owner declares the value of their share in their taxable wealth for the IFI, applying a discount if necessary to account for this lower liquidity. The rate of this discount is not rigidly set by law, allowing for some discretion, but also posing a risk of reassessment if the reduction seems excessive to the administration.
- Evaluate the market value of the property as a whole before applying the pro-rata of the share
- Apply a discount consistent with current case law, documenting the reason retained
- Keep a written record of the evaluation method used, especially in case of an audit
The tax management of a property in joint ownership is based on a constant principle: each co-owner is responsible for their own declaration, for their own share. No mechanism allows one to declare for others. Checking the exact nature of the holding (joint ownership, severance, or a combination of both) remains the first reflex to have before any entry on tax platforms.
