You have found the apartment. The agent is telling you that there are two other offers on the table. You are ready to sign the offre d’achat next week — and you have no idea that signing it may already bind you to a purchase you haven’t fully investigated, with co-ownership charges you haven’t read and unauthorized works the seller has never disclosed.
This is the scenario I see play out with foreign buyers in Paris more often than I care to count. The French property transaction appears notarised, supervised, safe. It is — on the surface. Beneath it, a series of legal mechanisms operate entirely in the seller’s interest unless you know how to read them. This checklist is what your notaire will probably not volunteer to explain to you.
Can a foreigner buy property in Paris?
Yes, without restriction. France imposes no nationality requirement, no residence condition, and no prior authorisation on foreign nationals purchasing real estate. Whether you hold an EU passport or a non-EU one, whether you are resident in France or buying from abroad, the legal capacity to acquire is identical to that of a French citizen.
One question I hear frequently: does owning property in Paris give you the right to live in France? No. Property ownership confers no immigration status. If you are a non-EU national, you will need the appropriate visa to stay beyond ninety days in any 180-day period, regardless of what you own.
The complications are not about eligibility. They are about process, language, and a transactional structure that concentrates risk in places most foreign buyers never look.
How the French property purchase works: the essential structure
The Paris purchase follows a two-step sequence that has no exact equivalent in common law systems.
The first step is the avant-contrat — either a compromis de vente (bilateral promise) or a promesse unilatérale de vente (seller’s unilateral promise). This is a binding preliminary contract, not a mere letter of intent. Once signed, both parties are in principle committed to complete.
The second step is the acte authentique de vente — the deed of sale executed before a notaire, which constitutes the actual transfer of title. This typically occurs two to three months after the avant-contrat.
Between the two steps, the buyer conducts financing, due diligence is formally completed, and the notaire carries out the title searches. The fatal mistake most foreign buyers make is treating the avant-contrat as provisional when it is, in most respects, final.
The offre d’achat: the trap before the trap
Before the compromis, an estate agent will often ask you to sign an offre d’achat — a written purchase offer at a specified price. Most foreign buyers treat this as a preliminary, non-binding expression of interest. It is not.
Once the seller countersigns and accepts an offre d’achat, both parties are in principle contractually bound. The majority position among French practitioners is that the ten-day right of withdrawal under article L. 271-1 of the Code de la construction et de l’habitation applies to the compromis de vente — not to the offre d’achat. This question has not been definitively settled by the Cour de cassation, and some courts have extended the L. 271-1 protection to accepted purchase offers that are sufficiently detailed to constitute a binding synallagmatic agreement. The prudent approach is to behave as though the offre d’achat is binding the moment the seller accepts it, and to structure your protection through the conditions of the offer itself rather than through any assumed right of withdrawal. If you walk away from an accepted offer without a contractual basis, the seller can theoretically sue for specific performance or damages.
The practical risk is this: you sign an offre d’achat under competitive pressure, without having read the état daté, the procès-verbaux d’AG, or the diagnostics. The seller accepts. You then discover a €40,000 works liability or an illegal mezzanine. Your only legal exits are the suspensive conditions written into the subsequent compromis — and those need to have been drafted intelligently.
The minimum protection: never sign an offre d’achat before your own notaire or lawyer has reviewed the document and confirmed which conditions protect you. Better still, keep the offer expressly conditional on the satisfactory review of all co-ownership documentation.
The compromis de vente: your most exposed moment
The ten-day right of withdrawal
Under article L. 271-1 of the Code de la construction et de l’habitation, an individual buyer purchasing residential property has a ten-day cooling-off period (délai de rétractation) running from the day after notification of the signed compromis. During this window, you may withdraw without penalty and recover any deposit paid.
After day ten, withdrawal is only possible if a suspensive condition (condition suspensive) fails — typically the financing condition — or if the seller is in breach. Otherwise, if the deposit has been characterised as a clause pénale (which is the standard in Parisian compromis), the seller may either bring a claim for specific performance or retain your deposit as a contractual penalty, typically fixed at 10% of the purchase price.
The ten-day period is your last free exit. Use it to have the full documentation package reviewed before it expires, not after.
Compromis vs promesse unilatérale: the difference that costs money
In a compromis de vente, both buyer and seller are bound. In a promesse unilatérale de vente, only the seller is bound; the buyer retains the option to complete or not, in exchange for an option premium (indemnité d’immobilisation) of typically 5–10% of the price.
Paris agents overwhelmingly use the compromis because it suits sellers. If you want the structural protection of the promesse — the ability to walk away from the deal without cause during the option period — you must request it explicitly and early. Few sellers will agree, but the negotiating position is stronger than buyers assume.
The Loi Carrez trap
What it measures — and what it does not
The loi Carrez (Law no. 96-1107 of 18 December 1996) requires that every sale of a co-ownership lot include a certified measurement of the surface privative — the private living area of the property. The measurement excludes any space with ceiling height below 1.80 metres, open balconies, terraces, garages, cellars, and parking spaces, regardless of how the agent’s listing describes them.
The Carrez measurement must appear in the compromis. If the actual surface is more than 5% smaller than the declared figure, you have one year from the date of the acte authentique to bring a price reduction action proportional to the shortfall. You receive no compensation below the 5% threshold.
Where the Carrez trap bites
The measurement is conducted by the seller’s chosen diagnostiqueur. In older Paris apartments — Haussmannien stock, pre-war buildings — you will regularly find mezzanines constructed without permit, converted chambre de bonne floors, or roof-slope areas that are habitually included in estate agent advertising but do not count under Carrez.
A 65 m² apartment advertised may carry a Carrez certificate of 57 m². The difference does not entitle you to withdraw from the sale — only to a price reduction if it exceeds 5%. The agent’s floor plan and the Carrez figure are legally distinct documents. Always verify which number drives the price per square metre in your negotiations.
Works without permit: the hidden liability you inherit
This is the trap that catches the most sophisticated buyers and that almost no guide addresses.
In Paris’s older residential stock, unauthorised works are endemic. Sellers — and their predecessors — have over decades created mezzanines, removed load-bearing partitions, opened new doorways, or transformed chambres de bonne into bathrooms, all without obtaining the required building or planning authorisation from the city.
When you acquire the property, you acquire these violations. You become, in the eyes of the planning authority (Mairie de Paris), the responsible party. You can be required to restore the property to its original state at your own expense. Under French planning law, the limitation period for enforcement of planning violations runs for ten years from the completion of the works — not from the date they come to the attention of the authorities. Once ten years have elapsed since completion, the violation can no longer be sanctioned. The practical difficulty is proving when the works were completed: a seller who cannot produce dated invoices, a building permit, or a déclaration d’achèvement de travaux for significant modifications cannot establish when the ten-year clock started running — which is exactly why the violation remains a liability you will carry until you can prove otherwise.
How to detect them: compare the current layout against the original building permit (permis de construire) or the état descriptif de division (the co-ownership partition document) on file with the notaire. Where recent works were carried out by the seller, ask for the building permits or déclarations préalables de travaux. If they cannot be produced for significant structural modifications, treat the acquisition as carrying undisclosed planning liability. A clause in the compromis requiring the seller to regularise or indemnify is negotiable but often contested.
The copropriété: the financial iceberg
This is where the most serious exposures lie for foreign buyers unfamiliar with the French co-ownership structure.
What you inherit from the seller
When you acquire a lot in a copropriété, you become, on the date of the acte authentique, a co-owner and a member of the syndicat des copropriétaires. The état daté — produced by the syndic at the seller’s request — discloses the seller’s outstanding balance, any sums owed to the syndic, and any works voted by the assemblée générale but not yet invoiced.
Read the état daté carefully. Works voted by the assemblée générale bind all subsequent owners. If the co-owners voted six months ago to replace the building’s heating system at a cost of €900,000 and the works are scheduled for next year, you — as the new owner of a 3% share — will receive an invoice for approximately €27,000 shortly after completing your purchase. The seller is under no obligation to volunteer this unless the état daté makes it visible.
The procès-verbaux d’assemblée générale
The loi ALUR of 2014 requires that the last three years of general meeting minutes (procès-verbaux d’AG) be communicated to the buyer with the avant-contrat. These minutes contain the building’s entire institutional memory: contested works, ongoing disputes, failed votes on deferred maintenance, litigation between the syndic and third parties.
The counter-intuitive move most buyers miss: you are legally entitled to receive the procès-verbaux only at the compromis stage. But nothing prevents you from requesting them before making any offer — as a condition of entering into negotiations. A seller who refuses to share three years of meeting minutes before signature is telling you something. A well-advised buyer makes this request systematically and uses the response as a filter, not a formality.
The règlement de copropriété: use restrictions matter
The règlement de copropriété defines the permitted uses of the private lots and common areas in the building. For foreign buyers who intend to operate a short-term rental, run a home office, or undertake significant modifications, this document is critical. Many Paris co-ownership rules contain a clause bourgeoise restricting use to residential purposes only, which can prohibit both professional activity and tourist rentals. Violation of these rules is enforceable by the syndic and the courts.
Ask for the règlement de copropriété before signing the offre d’achat, not after.
The carnet d’entretien
Every co-ownership building must maintain a carnet d’entretien — a maintenance log recording past works, ongoing contracts, and the technical condition of common parts. Ask for it explicitly. It will tell you whether the building has a history of deferred maintenance and whether the syndic is managing the property actively or reactively.
Sitting tenants: the problem no one mentions
A Paris apartment advertised and contracted for sale as libre (vacant) can contain a sitting tenant you will inherit.
This happens most frequently in two scenarios. First, the apartment has an attached chambre de bonne — a small room on a separate floor — which the seller’s own notaire has overlooked as part of the lot and which is occupied by a tenant under a separate lease. Second, the seller has been negotiating with a tenant to vacate and the negotiation collapses between the offre d’achat and the acte authentique.
French tenant protection law makes eviction extraordinarily slow — eighteen months to two years in contentious cases, through a process that includes mandatory conciliation, the winter moratorium (trêve hivernale, from November 1 to March 31 during which physical evictions cannot be carried out), and ultimately enforcement by bailiff, which itself requires prior notification to the prefect before any forcible removal can proceed. Acquiring an apartment with a sitting tenant you did not bargain for is a material alteration of the transaction.
Protection: the compromis must contain a representation that the property will be delivered vacant, with a suspensive condition (or at minimum a right to withdraw and recover the full deposit) if the property is not vacant on the closing date. Confirm occupancy status independently before signing.
État des risques and the diagnostic package
The état des risques et pollutions
The état des risques et pollutions (ERP) is a mandatory document, valid for six months, that declares whether the property lies within a zone exposed to natural hazards (flooding, earthquakes, ground movement), technological hazards, mining hazards, radon, or soil pollution. It must be appended to the compromis.
For Paris specifically, the relevant risks include flood exposure. Properties in arrondissements bordering the Seine — and in parts of the city historically affected by the Seine floods — may carry flood exposure that directly affects insurability and resale value. The ERP tells you the zone. It does not tell you the cost of the risk. Ask your insurer for a quote before signing the compromis, not after.
The mandatory diagnostic package
French law requires a bundle of technical diagnostics (dossier de diagnostic technique, DDT) appended to the compromis and acte authentique. For an apartment in Paris, this typically includes:
Amiante (asbestos): mandatory for buildings with a building permit pre-dating July 1, 1997. Presence of asbestos in non-degraded condition does not prevent sale but must be managed.
Plomb (lead paint): mandatory for buildings pre-dating January 1, 1949. Elevated lead levels require disclosure and carry renovation obligations for rental properties.
Électricité and gaz: mandatory if the installation is more than fifteen years old. These are information diagnostics — they flag non-compliant installations but do not legally compel works before sale.
DPE (energy performance): classifies the property from A (most efficient) to G (least). Under the loi Climat et Résilience (22 août 2021), G-rated properties have been prohibited for new long-term residential leases (and renewals) since January 1, 2025. F-rated properties face the same prohibition from January 1, 2028, and E-rated properties from January 1, 2034. A G- or F-rated apartment you intend to rent long-term is an investment that requires factoring renovation costs into the acquisition price before you sign anything.
The critical limitation of all diagnostics is one most buyers misunderstand: these documents describe the condition at the date of the inspection. They are not guarantees. The electricity diagnostic may flag non-conformities without specifying what a full rewire will cost. The asbestos report may state « matériaux contenant de l’amiante présents — aucune dégradation observée » — which simply means the problem is deferred, not absent.
The droit de préemption: when Paris can buy instead of you
The City of Paris holds a droit de préemption urbain (DPU) across its entire territory. Every sale is notified to the city hall via a Déclaration d’Intention d’Aliéner (DIA) filed by the notaire. The city has two months to exercise its pre-emption right and substitute itself as buyer, at the agreed price.
In practice, the city rarely exercises its DPU on individual apartments. But the two-month waiting period is built into every Paris transaction and affects your closing timeline.
In certain zones, Paris has implemented a droit de préemption urbain renforcé (DPUR). In these areas, the standard exceptions — which normally exempt standard co-ownership lots — do not apply, and the city can pre-empt individual apartment transactions. The DPUR zones are mapped in the bioclimatic PLU adopted in 2024. Your notaire will file the DIA and identify whether the property is in an enhanced zone. If it is, factor in the possibility of the city exercising its priority right as a theoretical — if remote — closing risk.
The ABF constraint: monuments historiques and what they mean for works
Almost every Paris apartment sits within 500 metres of a listed historic monument. This means that any exterior works — facade restoration, window replacement, installation of air conditioning units, rooftop modifications — require approval from the Architecte des Bâtiments de France (ABF). The ABF can impose material requirements (paint colours, window materials, window division) that significantly affect the cost and timeline of any renovation.
This constraint also applies to interior structural works that affect the facade or roof. Buyers who intend to carry out significant renovation should verify the ABF constraints applicable to their specific property before signing. An architect familiar with Paris heritage regulations can assess this rapidly from the address.
Short-term rental: what Loi Le Meur means for foreign buyers
Many foreign buyers purchase Paris apartments intending to use them as pied-à-terre for part of the year and offset costs via short-term rental platforms. The regulatory landscape changed significantly with the loi Le Meur of November 2024. This is not background information. It is a condition that directly affects the business case for your purchase.
The 90-day cap for primary residences
If the apartment is your primary residence — defined as the place where you live for at least eight months per year — you can rent it short-term for a maximum of 90 days per year (down from 120 before January 2025). All short-term rentals must be registered with Paris city hall and display the registration number in every listing.
Secondary residences: effectively restricted
If the apartment is not your primary residence — which is almost always the case for a non-resident foreign buyer — renting it short-term requires a changement d’usage authorization from the City of Paris, which in most central arrondissements also requires a compensation mechanism (converting equivalent commercial space to residential use). In practice, this authorization is extremely difficult to obtain and expensive when it is possible at all. Foreign buyers who plan to use a Paris apartment primarily as an investment rental should consider this a near-prohibition in central Paris.
The co-ownership veto under Loi Le Meur
The loi Le Meur introduced a mechanism allowing co-ownership associations to vote, by a two-thirds majority of co-owners present or represented at the assemblée générale, to prohibit or restrict tourist rentals in the building — even retroactively against lots that were already operating as STR. If your building’s règlement de copropriété was previously silent on the matter, a subsequent two-thirds AG vote can bar you from operating a short-term rental you thought was permitted when you bought.
Before purchasing any apartment you intend to rent short-term, verify: (1) whether the règlement de copropriété already prohibits it; (2) the composition and sentiment of the AG — a building with active retirees and primary residents is a building that will vote against tourist rentals at the next opportunity.
The DPE constraint on short-term rentals
The loi Le Meur introduced energy performance requirements for furnished tourist rentals, with a calendar that is distinct from — and in some respects more restrictive than — the long-term rental rules. The rules are structured in two layers that it is important not to confuse.
For any short-term rental that requires an authorisation de changement d’usage — which, in Paris, means virtually all secondary residence STR — the property must already present a DPE rated A to E to obtain that authorisation. In practical terms: F- and G-rated properties are already ineligible for new changement d’usage authorisations since November 21, 2024. This affects most foreign buyers who are non-residents, since their Paris apartment will almost always be classified as a secondary residence.
For STR that do not require a changement d’usage (primarily the short-term rental of a genuine primary residence), the general national requirement is that all STR must be rated A to D from January 1, 2034.
The practical consequence for a non-resident foreign buyer: if you intend to operate a short-term tourist rental and the property is not your primary residence, and the DPE is F or G, you are already barred from obtaining the necessary authorisation under the loi Le Meur. Do not assume a transitional grace period exists for this category of use.
The notaire: what they are, what they do, and whose side they are on
What the notaire is — and why this role has no equivalent in common law systems
In many common law countries — the United Kingdom, Australia, Singapore — a real estate transaction is handled by a solicitor or conveyancer who represents one party and owes that party a duty of care. In the United States, practice varies significantly by state: some states require an attorney at closing, others do not, and many transactions are handled through escrow agents and title insurance companies with no lawyer present at all.
France operates on an entirely different model inherited from Roman law and codified under the Napoleonic system. The notaire is not a private lawyer. They are a public officer appointed by the Ministry of Justice, exercising a state delegated function: the authentication of legal acts. When a notaire signs a deed, it becomes an acte authentique — a public document that carries the force of law, is enforceable without further court proceedings, and is registered in the national land registry.
This function does not exist in common law systems. The nearest equivalent would be if the Land Registry itself were present at every closing and had to certify that the transaction was legally valid. The notaire is that presence.
By law, every property transfer in France must pass through a notaire. There is no exception. The notaire is mandatory regardless of whether the parties are French or foreign, resident or non-resident, paying cash or borrowing.
What the notaire actually does
The notaire’s job in a property transaction covers three main categories.
Title verification. Before closing, the notaire searches the title history of the property — typically going back thirty years, in line with the main acquisitive prescription period under French civil law — verifies that the seller has capacity to sell, and confirms that no lien, mortgage, or encumbrance (hypothèque, privilège de prêteur de deniers, inscription de sûreté) will survive the transfer unsatisfied. Outstanding charges are paid from the sale proceeds before disbursement to the seller.
Document collection and compliance. The notaire assembles the mandatory documentation package: urban planning searches, pre-emption right declarations, co-ownership documents, diagnostics, and the tax information that French law requires to be verified before title transfer.
Authentication and registration. At closing, the notaire reads the deed to the parties, certifies that it was signed in their presence, collects the sale price and the frais de notaire, and then registers the transfer with the service de la publicité foncière (SPF), the French land registration authority. Under French law, ownership transfers to the buyer at the moment the acte authentique is signed — not at registration. Registration makes the transfer opposable to third parties: until it is published with the SPF, the buyer’s title cannot be enforced against a subsequent buyer or creditor. In practice, the notaire undertakes registration immediately after closing, so the gap is a matter of administrative timing rather than legal exposure.
The frais de notaire — commonly called « notaire fees » — are not primarily the notaire’s remuneration. They consist overwhelmingly of transfer taxes and registration duties (the total rate varies by département but runs to approximately 5 to 6% of the purchase price for existing residential properties in most of metropolitan France), plus the notaire’s own regulated emoluments and administrative disbursements. The total frais de notaire for an existing property are commonly cited as approximately 7 to 8% of the purchase price.
Whose side are they on?
This is the question no one in the French transaction ecosystem wants to answer clearly, so I will.
The notaire’s obligation runs to the legality of the transaction — not to your interests. Their professional duty is to ensure that the deed is valid and correctly executed. It is not their function to identify whether the deal is commercially advantageous for you, to negotiate on your behalf, to flag risks that the documentation technically discloses but that you might miss, or to advise you on whether the price you are paying reflects the true condition of the asset.
In the standard Paris transaction, the notaire is chosen by — and has an ongoing professional relationship with — the seller or the estate agency. They will explain the process. They will answer your questions if you ask them. They will not, as a rule, proactively flag that the co-ownership has €48,000 in unpaid charges if the état daté technically discloses it buried in line 7 of a four-page document.
What most foreign buyers never discover: you have the absolute right to appoint your own notaire (notaire de l’acquéreur) at zero additional cost to you. The notarial fees — which in France are regulated and paid by the buyer — are split between the two notaires. The total cost is identical whether one or two notaires are involved. The seller’s notaire manages the file; your notaire reviews it in your interest.
In a transaction conducted in a language you do not fully command, on a legal system you did not grow up with, appointing your own notaire is not a luxury. It is the minimum due diligence. The fact that estate agents systematically omit to mention this option is not an accident.
The notaire is also distinct from an avocat (lawyer admitted to the bar). If you need someone to negotiate clauses in your favour, to advise you on whether particular suspensive conditions are adequate, to review the règlement de copropriété for legal risk, or to assist you after closing in a dispute — that is the function of an avocat, not a notaire. Both can be involved in the same transaction. For a foreign buyer navigating a complex Parisian purchase, having both is the standard of care, not an excess.
French inheritance law: the trap that strikes after death
This is a risk that no competitor guide addresses and that can have devastating consequences for foreign buyers who purchase Paris property without professional advice on the succession structure.
French law applies the principle of the réserve héréditaire — mandatory inheritance shares for children — to immovable property located in France. This means that, absent specific planning, your Paris apartment will be distributed on your death in accordance with French succession law, which reserves a fixed portion of the estate for your children and restricts your ability to leave the full property to a surviving spouse or other beneficiary.
EU citizens benefit from EU Regulation 650/2012 (Brussels IV), which allows them to elect the law of their nationality to govern their succession, including French real estate. By making this election in a will or a declaration, an EU citizen can have their French property distributed under, say, English or German law, which may be more flexible.
Non-EU nationals — Americans, British post-Brexit, Australians, Singaporeans — cannot use Brussels IV. Their French real estate will be governed by French succession law regardless of their intentions and regardless of what their home country will says. A married non-EU buyer with children from a prior relationship who intends to leave their Paris apartment entirely to their spouse may find this impossible under French law without specific structuring.
Solutions exist: acquisition through an SCI with appropriate share transfer provisions, contractual regimes under marital agreements, life insurance structures. These must be designed before purchase, not after. Consult a notaire and an avocat specialised in international succession before completing.
The SCI: buying through a company
Some foreign buyers — particularly those acquiring for investment or estate planning purposes — choose to purchase through a société civile immobilière (SCI). The SCI is a French civil law company whose purpose, as defined in its statuts, typically encompasses the holding, management, and if applicable rental of real estate. Its shares can be transferred by gift or bequest more easily than direct real estate ownership, which can reduce inheritance tax exposure and facilitate succession planning.
The SCI is not a panacea. It adds administrative costs (annual accounts, registered agent), has specific tax treatment implications for rental income (depending on whether the SCI is subject to income tax or corporate tax), and requires careful drafting of its statuts. For non-EU buyers concerned about the inheritance law issue described above, the SCI may be part of the solution — but only as part of a comprehensive structure designed by an avocat and a notaire working together.
Do not create an SCI based on an internet search. The choice of tax regime and the drafting of the bylaws have permanent consequences.
Specific traps for foreign buyers
Power of attorney
If you cannot attend the signing of the acte authentique in person, you must grant a procuration authentique — a notarised power of attorney. If this document is executed abroad, it requires apostille under the Hague Convention or legalisation, depending on your country. The process takes time. A non-apostilled, non-translated POA will be refused by the notaire on the day of signing, and you will have missed your completion date.
Plan the POA well in advance — the process can take several weeks once you factor in notarisation, apostille or legalisation, translation, and courier time. If you are in a country that is not party to the Hague Convention, the legalisation chain is longer still. Do not leave this until the closing date has been set.
French tax identification number
You will need a French tax identification number (numéro fiscal) to complete the purchase. For non-residents, this is obtained from the Direction des impôts des non-résidents (DINR). The process is not instantaneous. Apply early.
Anti-money laundering compliance
French notaires are mandated anti-money-laundering reporting entities. Any foreign national transferring significant funds from a non-EU bank account should expect to provide detailed source-of-funds documentation: bank statements typically covering twelve months, proof of the origin of the funds (employment income, proceeds from a prior sale, inheritance), and a written explanation if the source is complex. The notaire may refuse to proceed without satisfactory documentation. Prepare this file before you find the apartment, not on the eve of the compromis.
American buyers and FATCA
The Foreign Account Tax Compliance Act imposes additional compliance requirements on foreign financial institutions dealing with US persons. Many French banks have historically declined to extend mortgages to US citizens because of the compliance burden. If you are an American buyer, verify your financing options before you begin your search — not after you have committed to a price.
American buyers must also declare their French real estate for US tax purposes and, if they own shares in an SCI, treat that as a foreign corporation or partnership for US tax reporting. The reporting requirements are not trivial and require a tax advisor experienced in US-French matters.
Non-resident taxation
Owning French property as a non-resident exposes you to French taxation on:
Rental income: taxed in France at a minimum rate of 20% on the income tax component (rising to the standard progressive rates above approximately €29,000), subject to applicable tax treaties. EU/EEA residents who can demonstrate they are covered by another EU/EEA social protection scheme benefit from a reduced social charge rate of 7.5% instead of the standard 17.2%. Non-EU residents generally owe the full 17.2% social charges, which, combined with the 20% minimum income tax, produces a combined floor rate of approximately 37%.
Capital gains on sale: taxed in France at 19% plus social charges of 17.2%, with progressive abatement based on years of ownership. Full exemption from capital gains tax is reached after twenty-two years of ownership; full exemption from social charges after thirty years.
Fiscal representative on resale: if you are a non-EU, non-EEA resident and the transfer price exceeds €150,000, you are required to appoint a French fiscal representative (représentant fiscal accrédité) approved by the tax authorities. Note that the threshold is the sale price, not the gain — the obligation applies even if you sell at a loss. This person assumes joint and several liability for your French capital gains tax. Their appointment has a cost — typically a percentage of the transaction — and must be arranged well in advance of signing the acte de vente on your exit.
IFI (impôt sur la fortune immobilière): if your French real estate holdings exceed €1.3 million in net value, you are subject to IFI as a non-resident on your French assets only. The tax is progressive, beginning at 0.5% and reaching 1.5% for portfolios above €10 million.
Taxe foncière: the annual property tax, payable by the owner on January 1 of each year. At completion, the notaire will typically propose a proratisation — the seller reimburses the buyer for the fraction of the year following the transfer date. This is market practice, not a legal obligation, but is standard. Ask the seller for the last two taxe foncière notices to estimate the annual amount.
Taxe d’habitation sur les résidences secondaires: if the property is your secondary residence (which it almost always will be for a non-resident foreigner), you will pay this annual tax. For primary residences, this tax was abolished in 2023; for secondary residences, it remains in force and in some Paris zones includes a surcharge for housing shortage areas (zone tendue), which Paris is.
Taxe sur les logements vacants: if the property is left empty for more than one year and is not a primary residence, you may be subject to the vacant property tax. Paris, as a zone tendue, applies this tax at significant rates (17% in the first year, rising to 34% thereafter). If you intend to leave the property entirely empty for extended periods, this tax applies.
Your home country may have a tax treaty with France that mitigates double taxation. The treaty determines which country has primary taxing rights and whether a credit mechanism applies. This analysis should be done before purchase, not after.

A final word on what looks safe but isn’t
The French notarised transaction gives foreign buyers a false sense of security. The presence of a public officer, the formal document bundle, the regulated fees — these create an appearance of protection that does not extend to the content of what you are agreeing to.
The diagnostics are true on the day they are done. The état daté is accurate as of its date. The procès-verbaux are complete but not interpreted for you. The notaire’s role is to authenticate, not to advise.
The asymmetry of information in a Paris apartment purchase systematically favours the seller. Correcting it requires requesting documents early, reading them carefully, appointing independent legal counsel, and treating the ten-day withdrawal period as what it actually is: your last negotiating position, not an administrative formality.
