A primary residence is the property where a taxpayer actually and habitually lives. This tax classification grants full capital gains exemption on resale, the removal of housing tax since 2023, and various advantages tied to subsidised loans. In 2026, the distinction between primary and secondary residence remains a major consideration for any Paris buyer.
Introduction
Buying an apartment in Paris means an investment of anything from 500,000 euros to over 2 million for family properties in the central arrondissements. Whether a property qualifies as a primary residence directly determines its tax treatment on resale. An apartment bought for 800,000 euros and sold for 950,000 euros produces a capital gain of 150,000 euros. If the property is your primary residence, that gain is fully exempt from tax. If it is a secondary residence, the tax can reach 54,000 euros (36.2% of the gain). Understanding the qualification rules is the starting point for any purchasing strategy in Paris.

The tax definition of a primary residence
Under Article 150 U of the French General Tax Code, a primary residence is the property where the taxpayer habitually and actually lives. Three conditions, taken together, define it. The property must be occupied for most of the year. It must be the real place of residence of the taxpayer and their family. And it must be the centre of their professional and personal interests.
This contrasts with a secondary residence, which is any property you own without living in it as your main home. A pied-à-terre in the 5th arrondissement used three days a week for work, while the family lives in Versailles, is a secondary residence.
Qualification is assessed on the day of sale, not at the time of purchase. A property bought as a rental investment and later turned into a primary residence may qualify for the capital gains exemption, provided real occupancy is established by the time of sale.
Criteria used by the tax authorities
In a tax audit, the authorities weigh a body of evidence to verify that a property really is the taxpayer’s primary residence. The criteria most often examined are these.
The address declared on tax notices and the income tax return is the first indicator. Work address and commuting distance come second. Children’s schooling in the property’s catchment area is looked at closely. Water, electricity and gas consumption is analysed to confirm regular occupancy. The address used for bank accounts, car insurance and the electoral roll completes the picture.
A buyer who acquires an apartment in the 16th arrondissement while keeping a house in the suburbs must ensure all of these point to the Paris address to claim primary residence status.
Capital gains exemption: conditions and limits
The capital gains exemption on a primary residence is the main tax advantage attached to this classification. It is total: neither income tax (19%) nor social contributions (17.2%) apply, regardless of the amount of the capital gain.
To qualify, three conditions must be met on the day of sale. The property must be your primary residence when it is put up for sale. It must not have been rented, even in part, between listing and the signing of the final deed. And you must have occupied it genuinely and habitually.
Administrative practice allows a reasonable period between moving out and the actual sale. This is assessed case by case but generally does not exceed 12 months. Beyond that, the authorities may challenge the exemption. If you leave your Paris apartment for a new home before selling the old one, sign the preliminary contract as soon as you can.
By comparison, a secondary residence sold after less than 22 years of ownership is subject to tax ranging from 19 to 36.2%. See our guide on property owner taxes in Paris for a complete overview of the tax landscape.
Housing tax and primary residence in 2026
Since 2023, housing tax on primary residences has been eliminated for all taxpayers. However, housing tax on secondary residences remains in place and has been strengthened in Paris.
In 2026, Paris applies a 60% surcharge on the housing tax for secondary residences, under the Paris Council’s resolution. For a 70 sqm apartment in the 3rd arrondissement with a cadastral rental value of 3,500 euros, the secondary residence housing tax can reach 2,800 to 3,200 euros a year.
This surcharge comes on top of the property tax, which remains due on all properties. Qualifying as a primary residence therefore removes a significant annual expense.
Special cases: expatriates and multiple residences
Expatriates buying in Paris are in a particular position. A non-resident French taxpayer who buys an apartment in Paris cannot classify it as a primary residence for French tax purposes, even if they stay there regularly. The property is treated as a secondary residence, subject to the surcharged housing tax and to capital gains tax.
A partial exemption does exist for non-residents on the first sale of a property in France. It is capped at 150,000 euros in net capital gains and requires the seller to have been tax-resident in France for at least two consecutive years before the sale.
For couples whose workplaces are far apart, primary residence status turns on where the family lives. An executive working in Lyon from Monday to Friday whose family lives in an apartment in the 15th arrondissement can claim the latter as a primary residence.

Primary residence and subsidized mortgage loans
Qualifying as a primary residence opens access to advantageous financing schemes not available for secondary residences or rental investments.
The Interest-Free Loan (PTZ) is reserved for first-time buyers purchasing their primary residence. In 2026, the PTZ has been refocused on new-build properties in high-demand zones (zone A and Abis for Paris) and older properties needing renovation in lower-demand zones. For a new-build purchase in Paris, the PTZ can finance up to 40% of the cost, within a ceiling that depends on household size. For a couple with one child, the maximum PTZ amount in zone Abis can reach around 138,000 euros.
The Prêt Paris Logement is a grant from the City of Paris designed to help Parisian households buy their home. This interest-free loan, which can be combined with the national PTZ, is conditional on buying a primary residence within Paris intra-muros.
Mortgage rates are generally better for primary residence purchases than for rental investments. In 2026, the average spread is 0.15 to 0.30 points, a saving of 10,000 to 25,000 euros in interest on a 500,000 euro mortgage over 20 years.
Borrower insurance is also affected. Coverage conditions and premiums may vary depending on the property’s purpose. For a primary residence, insurance typically covers death, total permanent disability, and temporary incapacity for work. For a rental investment, coverage is often limited to death and disability.
FAQ
How long must you live in a property for it to qualify as a primary residence?
There is no statutory minimum duration. The French tax authorities consider as primary residence the place where you effectively and habitually reside as of January 1 of the tax year. In practice, occupancy of less than 6 months per year is insufficient.
Can you have two primary residences in France?
No. Each taxpayer can have only one primary residence for tax purposes. In case of doubt, the tax authorities use the most habitual place of effective residence, determined by criteria such as professional address, children’s schooling, and energy consumption.
Does the capital gains exemption apply to expatriates selling their former home?
Non-resident French taxpayers benefit from a partial exemption on the first sale of a property in France, capped at 150,000 euros in capital gains. This exemption is subject to conditions, including having been tax-resident in France for at least two years.
