The status of primary residence in France is based on a set of indicators that the tax administration cross-references during each declaration. A property occupied for the majority of the year is not always sufficient to guarantee this status, especially when the taxpayer owns multiple properties or works remotely from another country.
Tax reclassification of nomadic teleworkers: an underestimated risk
Since 2025, the tax administration has intensified its checks on teleworker profiles who spend more than 183 days outside of France while maintaining a declared primary residence in the territory. An updated BOFiP circular regulates these controls, and adjustments for reclassification as a secondary residence are on the rise.

The mechanism is simple: if the taxpayer cannot demonstrate effective and habitual occupation of the declared property, the tax authorities will reclassify the property. The direct consequence is the loss of tax benefits associated with the primary residence, notably the exemption from capital gains in the event of a sale.
To understand the legal foundations of this notion, the definition of primary residence according to Guide Immo details the criteria used by the administration. This framework is the starting point for any serious analysis of one’s situation.

Criteria for occupying the primary residence: beyond the eight-month rule
The commonly cited threshold is that of an occupation of at least eight months per year. This figure appears in tax doctrine and serves as the standard benchmark. The tax administration also considers the taxpayer’s situation as of December 31 of the tax year as the reference date.
This duration can be lowered in three specific cases:
- Health reasons forcing the taxpayer to reside elsewhere (prolonged hospitalization, specific care)
- Professional obligations requiring distance from the declared home (transfer, long-term assignment)
- Force majeure making occupation impossible (disaster, safety work)
The tax authorities do not settle for duration alone. They also examine the center of economic and family interests of the taxpayer. Workplace, children’s schooling, bank accounts, current subscriptions: these elements form a set of converging indicators.
Married or civil partnership couples: a notable exception
In the context of marriage or civil partnership, the administration allows each partner to declare their own primary residence when professional reasons justify two distinct homes. This tolerance is still conditioned on proof of effective occupation of each residence.
Seniors in nursing homes and maintaining the tax status of primary residence
Entering a nursing home presents a concrete problem. When a senior resides there for more than eight months in the year, their former home generally loses its status as a primary residence. Feedback from user associations indicates a trend towards a decrease in maintaining this status for long-term placements.
Judicial appeals on this subject increased by 40% in 2025, according to available data. The stakes are direct: losing the status results in the removal of the 30% deduction on the taxable base of the IFI, and any capital gains upon a potential sale of the property become taxable.
Maintaining the status remains possible when the taxpayer retains enjoyment of the property and can demonstrate an intention to return. However, if the property is rented out during the stay in the nursing home, reclassification as a secondary residence becomes almost automatic.
Seasonal rental of the primary residence: the 90-day limit becomes widespread
The Le Meur law adopted in 2024 allowed municipalities to reduce the maximum duration of seasonal rental of a primary residence to 90 days per year. Paris, Marseille, Nice, and Bordeaux were already applying this restriction. Since then, more than 50 new tourist municipalities have adopted this cap by the end of 2025.
Exceeding this threshold exposes the owner to two distinct risks:
- An administrative fine for non-compliance with local regulations on furnished tourist rentals
- A reclassification of the property as a secondary residence by the tax administration, resulting in the loss of associated exemptions
- The obligation to apply for a change of use of the property with the town hall, a cumbersome process in tight areas
This generalization alters the calculations for owners who relied on short-term rentals to offset their mortgage. The legal framework is tightening, and municipal controls have been equipped with automatic detection platforms.
Primary residence and cross-border workers: a stricter French definition than the European norm
Cross-border workers face an additional difficulty. The French definition imposes a minimum occupation of eight months to qualify a property as a primary residence. Some neighboring countries apply different criteria, leading to situations of double taxation or qualification conflicts.
A cross-border worker who works in Switzerland or Luxembourg but resides in France must prove that their French property is indeed their habitual home. The criterion of the center of economic interests may work against them if most of their income comes from abroad. Bilateral tax treaties provide for resolution mechanisms, but available data do not allow for a conclusion that these procedures are systematically favorable to the taxpayer.
The qualification of primary residence is not limited to a postal address. It involves a set of material proofs that the tax authorities can verify at any time. Property owners affected by professional mobility, placement in a nursing home, or seasonal rental activities should document their situation precisely before each tax deadline.
