Sale of the main residence: time frame for sale, outbuildings and cases where the exemption is retained or lost

Capital gains on the sale of your primary residence are exempt from tax, provided the property remains your primary residence on the day of the sale. If you have moved before selling, the French tax authorities (BOFiP) do not specify a maximum time limit. However, they state: "In a normal economic climate, a period of one year is generally considered the maximum." During the sale, the property must not be rented out or occupied free of charge by relatives or third parties, and the asking price is one of the factors considered in relation to prices on the local market. Outbuildings sold at the same time are exempt under the same conditions.

This page focuses on the time limit, the asking price, outbuildings, and whether the property retains or loses its status as a primary residence. It does not detail the calculation of taxable capital gains or other exemptions; see the page on capital gains tax for residents. It does not address non-residents, successive residences, or the exact starting point of the one-year period.

The principle: a complete exemption

According to service-public.gouv.fr (verified on 15/04/2026), you are "fully exempt" if you realize a capital gain on the sale of your primary residence. According to economie.gouv.fr (page written on 06/07/2026), the exemption covers income tax and social security contributions for the primary residence and its outbuildings.

The BOFiP (BOI-RFPI-PVI-10-40-10, version of 27/06/2023) specifies that the exemption is general in nature: the reasons for the sale, the type of property, and the amount of the capital gain are irrelevant. The condition applies to the property itself, not to the price.

Main residence: usual and effective

The BOFiP (Official Bulletin of Public Finances) defines principal residence as the owner's usual and effective residence, where they typically reside for the majority of the year. Temporary use is insufficient. In case of doubt, the BOFiP places the burden of proof on the taxpayer: "When doubt remains, the taxpayer is required to prove the actual residence by any means."«

The day of the transfer: the basic rule

The property must be the seller's primary residence on the date of the sale (BOFiP, § 180). The BOFiP excludes the following types of housing:

• given away for rent; ;
• occupied free of charge by members of the owner's family or by third parties; ;
• which have become vacant.

The exemption is also denied when occupancy at the time of sale is purely for convenience. For a property vacated and then put up for sale, the time limit described below sets the framework for assessment.

Regarding ascendants and descendants, the BOFiP (Official Bulletin of Public Finances) states: "The exemption cannot, in principle, apply to buildings occupied by the owner's ascendants or descendants." It provides an exception for two apartments located in the same building, the acquisition of which was necessitated by the number of dependents of the taxpayer: they are considered as forming a single dwelling unit.

The time it takes to sell after the move

The scenario in question: you have vacated the property, put it up for sale, and the sale has not yet been completed. The BOFiP (§ 190) sets out the following rules.

The impots.gouv.fr page "exempt capital gains" (modified on 28/09/2022) uses the same reasoning: exemption remains possible if the property was occupied until it was put up for sale and if the sale takes place within a normal period, in principle one year.

The BOFiP consulted does not specify a tolerated price difference or a starting point for the deadline. These two points are verified on a case-by-case basis.

Cases where the status of primary residence is retained

The BOFiP allows for several situations where the exemption applies despite a departure before the sale.

• A disaster. A building does not lose its status as a principal residence if the owner has had to leave it due to a disaster that renders occupancy impossible. The property must have been their principal residence on the day of the disaster; the owner must have had the property rebuilt without delay and completed the transfer of ownership as soon as the work was finished (§ 195).
• A buyer who already occupies the property. The BOFiP (Official Bulletin of Public Finances) states: "It is accepted that the exemption applies when the property is occupied by the future purchaser," with whom a preliminary sales agreement has been signed. The occupancy agreement must be linked to the sale, and the sale must be concluded within a reasonable timeframe after the preliminary agreement (§ 200).
• The departure of one member of the couple. If the ex-spouse occupied the dwelling until it was put up for sale, and the sale takes place within a normal period, the exemption is allowed, without any period imposed between the separation and the sale (§ 260 and § 270).

Outbuildings: cellar, garage, parking, maid's room

Immediate and necessary outbuildings sold at the same time as the main residence are exempt. Service-public.gouv.fr lists cellars, garages, parking spaces, and courtyards. The 2022 impots.gouv.fr website lists cellars, garages, and maid's rooms.

Sale of primary residence: numerical example (fictitious profile)

Situation. Thomas left his house, which was his primary residence. He immediately put it up for sale, without renting it out, at a price in line with market rates in his town, and kept proof of his efforts (advertisements, mandates). The sale was finalized 14 months after his departure. The gross capital gain was €80,000 (based on a hypothetical scenario; no fixed fees or other charges). He had owned the property for 15 years. The garage, located 600 meters away, was sold the same day.

Issue. The 14-month period exceeds the one-year benchmark. What are the financial implications if the exemption is not granted?

Strategy. The BOFiP (French Official Tax Bulletin) states that no maximum timeframe can be set in advance and that one year is generally the maximum period in a normal economic context. The assessment is made on a case-by-case basis: local market, asking price, absence of a rental agreement, and due diligence. Thomas documents these elements before the sale.

Result. If the exemption is granted, the capital gain is not taxed. If it were not granted, the approximate tax liability would be as follows, at rates of 19% and 17.2%, with allowances of 6% (income tax) and 1.65% (social security contributions) per year from the sixth to the fifteenth:

The income tax base remains below €50,000: the additional tax does not apply in this example.

This profile is fictitious. The amounts are hypothetical and unrelated to any actual case. The figure of €17,569.60 reflects the stakes: it does not indicate that the exemption would be denied in this particular case, which is assessed on a case-by-case basis. The calculation does not include sales costs.

Selling your main residence: what changes depending on your situation

• The time between your departure and the sale, and what happened in between: rental, occupancy by a relative, vacancy.
• The asking price, compared to prices on the local market.
• Your steps to put your property up for sale : advertisements, agencies, mandates.
• Your list of dependencies and their distance from the main residence.
• The sales dates of each outbuilding in relation to that of the residence.

The rule depends on your situation. No results are guaranteed.
