You live in New York, Dubai, Singapore or Sydney, and you own a flat in Paris, a house in Provence or a studio on the Côte d’Azur that you let out. Every year the same questions return: which French tax category applies to your rents, what you may deduct, which return to file from abroad, and what to do when the assessment looks wrong. The answers turn on one distinction above all others: an unfurnished letting is taxed as property income, while a furnished letting is taxed as business income, and each path carries its own rates, allowances and traps. This guide, written for owners who are not French tax residents, walks through both paths with the exact French references your file needs.

France taxes the building where it stands, not the owner where he lives. Whether you are American, Gulf-based, Asian or Australian, rent produced by a property on French soil is French-source income taxable in France, usually with relief against double taxation left to your country of residence. A neighbouring English-language guide on this site addresses the specific position of British owners after Brexit; this article covers non-resident owners generally, whatever their country of residence. For an overview of how our real estate team in Paris assists foreign owners, see our practice page.

I. How France taxes rental income when you live abroad

A. French-source income under French category rules, with a minimum rate

The starting rule is simple and strict. Article 164 A of the Code général des impôts (French tax code) provides: « Les revenus de source française des personnes qui n’ont pas leur domicile fiscal en France sont déterminés selon les règles applicables aux revenus de même nature perçus par les personnes qui ont leur domicile fiscal en France. » (Article 164 A of the Code général des impôts). In plain English: your French rents are computed under the same category rules as if you lived in France. An unfurnished flat falls into revenus fonciers (property income); a furnished flat falls into bénéfices industriels et commerciaux (business profits, universally shortened to BIC). The same article continues with the essential restriction: « Toutefois, aucune des charges déductibles du revenu global en application des dispositions du présent code ne peut être déduite. » No deduction from overall income is available to you. Charges attached to the property itself remain deductible within their category, but personal deductions from global income, which residents routinely use, are closed to non-residents.

The second mechanism to understand is the minimum rate. Article 197 A of the same code applies the progressive scale to non-residents but guarantees the Treasury a floor: the tax cannot fall below 20 percent on the part of net taxable income up to the top of the second bracket, and 30 percent above it, with reduced rates of 14.4 and 20 percent for income arising in the overseas departments (Article 197 A of the Code général des impôts). There is, however, a safety valve worth knowing: « toutefois, lorsque le contribuable justifie que le taux de l’impôt français sur l’ensemble de ses revenus de source française ou étrangère serait inférieur à ces minima, ce taux est applicable à ses revenus de source française. » If you can show that the French tax on all your worldwide income would be taxed at a lower average rate, that lower rate applies to your French income instead. Owners whose French rents are their only significant income, or whose worldwide income is modest, should test this option every year rather than accept the 20 percent floor by default. Claiming it means disclosing worldwide income to the French administration with supporting evidence, so prepare foreign tax assessments and income statements before filing.

This architecture has been tested before the highest administrative court. In a 2023 decision on a priority question of constitutionality, the Conseil d’État (Council of State, France’s supreme administrative court) refused to refer to the Conseil constitutionnel (Constitutional Council) a challenge arguing that the minimum-rate system discriminates between non-residents whose worldwide average rate falls below the floor and those whose does not. The court held that the derogation favours less well-off taxpayers and that its limited effect on the tax due creates no marked breach of equality in sharing public burdens (Conseil d’État, 9th-10th chambers combined, 3 February 2023, No. 468904). Practically, decision confirms that the 20 and 30 percent minima, together with the worldwide-rate relief, are settled law: build your file around them instead of hoping a court will sweep them aside.

Income tax is only half the bill. Social levies also apply to French-source property income of non-residents, and the official guidance of the French tax administration, updated in February 2026, gives the current figures: unfurnished rental income bears social levies at 17.2 percent, while furnished rental income bears 18.6 percent on income from 2025 onwards. Owners affiliated to a compulsory social security scheme in the European Economic Area or Switzerland, a category British residents kept after Brexit, are exempt from the CSG and CRDS components but still pay a 7.5 percent solidarity levy, claimed through specific boxes of the return. Check your affiliation position before budgeting: the différence between 17.2 or 18.6 percent and 7.5 percent changes the yield of the investment materially. Double tax treaties generally reserve the taxation of immovable-property income to the country where the building stands, with relief granted in your residence country, but treaty relief never removes the French filing and payment duty itself.

One administrative duty surprises many foreign owners: every owner must declare each property’s occupancy status to the tax authorities each year by 1 July through the “Gérer Mes Biens Immobiliers” section of the online account, stating whether the dwelling is a main or second home and, if you do not live in it, who occupies it and for which period. No change since the last declaration means no new filing. Missing this declaration can trigger a fixed fine per property, so calendar it alongside the income return.

B. Unfurnished lettings: property income, deductible charges and the micro-foncier option

When you let unfurnished, the computation starts from gross receipts and subtracts property charges. Article 28 of the tax code states: « Le revenu net foncier est égal à la différence entre le montant du revenu brut et le total des charges de la propriété. » (Article 28 of the Code général des impôts). Article 29 defines that gross base as the rents actually received plus expenses normally falling on the owner but passed to the tenant by the lease, while tenant service charges that belong to the tenant are ignored (Article 29 of the Code général des impôts). Keep the lease, rent statements and bank credits: they are the raw material of the file, and any review starts from them.

Two regimes then compete, and the choice changes the bill more than any other single decision. The régime micro-foncier (simplified property scheme) applies when annual gross rents do not exceed 15,000 euros: « Par dérogation aux dispositions de l’article 31, lorsque le montant du revenu brut annuel défini aux articles 29 et 30 n’excède pas 15 000 €, le revenu imposable correspondant est fixé à une somme égale au montant de ce revenu brut diminué d’un abattement de 30 %. » (Article 32 of the Code général des impôts). Gross rents of 12,000 euros thus produce taxable income of 8,400 euros, with no expense schedule required. For an owner with modest rents, a managing agent’s fee and no works, the micro-foncier is usually the economical and the safest answer from abroad. Watch its boundaries: the ceiling is assessed across the whole tax household’s property income, and exclusions apply to certain historic, subsidised or company-held properties, so verify eligibility before assuming it.

The régime réel (actual-expenses scheme) taxes rents minus deductible property charges, and it wins whenever real costs comfortably exceed 30 percent of gross rents. Article 31 lists the deductible charges for urban property, including repair and maintenance actually borne by the owner, insurance premiums, co-ownership provisions corresponding to deductible items, unrecovered tenant charges after departure, and improvement works on residential premises, while construction, reconstruction and extension remain excluded (Article 31 of the Code général des impôts). The year of a new boiler, a roof repair or a facade ordered by the copropriété (co-ownership) almost always justifies the régime réel, provided each invoice is genuine, paid and connected to the let building. The most litigated line is the one between deductible improvement and non-deductible reconstruction: rebuilding a ruin or adding floor space belongs to capital, not to deductible charges. Photographs before and after, detailed quotations and any planning permission decide more cases than legal argument, so assemble that evidence while the works are running.

What if charges exceed rents? Article 156 of the tax code allows a deficit in one income category to be set against overall income, with any excess carried forward for up to six years: « L’impôt sur le revenu est établi d’après le montant total du revenu net annuel dont dispose chaque foyer fiscal. » (Article 156 of the Code général des impôts). For a non-resident owner this relief is largely theoretical, because Article 164 A bars deductions from global income, and a property deficit with no other French income in the same category often has nowhere to go. Do not budget a purchase on the assumption that French losses will shelter other income: model the investment on the property’s own economics, and treat any usable deficit as a bonus rather than a plan. If you received no property income at all in the year, the administration asks you to tick box 4BN of return 2042 so the file is closed cleanly.

II. Furnished lettings, authorizations and protecting your position

A. Furnished rent is business income, and short-term letting may need prior authorization

Furnishing the flat changes its tax nature completely. Income from letting furnished accommodation, whether you own it or sub-let it as tenant, falls into the BIC category, and the administration applies social levies at 18.6 percent on income from 2025 (Article 34 of the Code général des impôts). A letting counts as furnished when the dwelling contains all the movable property a tenant needs for normal occupation, under the detailed list set by Decree 2015-981 of 31 July 2015. The practical consequence is immediate: a flat you thought was a simple rental becomes a small business for tax purposes, with BIC filing obligations, and the micro-BIC thresholds now bite early. Article 50-0 of the tax code keeps the micro-BIC scheme but sets the ceiling at only 15,000 euros of turnover for businesses whose main activity is letting meublés de tourisme (furnished tourist accommodation), against 83,600 euros for other businesses (Article 50-0 of the Code général des impôts). A Paris studio grossing 20,000 euros a year in short tourist stays is therefore outside the simplified scheme and must account under the actual BIC régime, with books to support it.

The tax question is inseparable from the town-hall question. In municipalities such as Paris, repeatedly letting a residential furnished flat for short periods to a transient clientèle is a changement d’usage (change of use) requiring prior authorization, and fines follow without it. The Cour de cassation, France’s supreme civil court, has settled the test: « le fait de louer un local meublé destiné à l’habitation de manière répétée pour de courtes durées à une clientèle de passage qui n’y élit pas domicile constitue un changement d’usage soumis à autorisation préalable. » (Court of Cassation, 3rd Civil Chamber, 18 February 2021, No. 19-13.191). In that case two lettings of four and six months within one year to occupants who did not live there were enough to qualify, and the court quashed the appeal judgment that had cleared the American-resident owners. The lesson for a foreign owner is blunt: even a handful of medium-term furnished lets in a single year can trigger the authorization requirement in a regulated city, and the owner’s non-residence is no defence.

The same day, the court rejected a challenge to the whole authorization system brought by a Paris property company. After the Court of Justice of the European Union validated the French scheme as a justified authorization regime protecting affordable long-term housing, the Cour de cassation dismissed the appeal and left the fines standing (Court of Cassation, 3rd Civil Chamber, 18 February 2021, No. 17-26.156). Owners sometimes hope European law will unlock short-term letting; that door is closed. Budget for the authorization procedure, including any compensation requirement in cities that impose one, or restrict yourself to lets that stay within the statutory exceptions: a nine-month minimum student lease, a one-to-ten-month bail mobilité (mobility lease) for tenants in training or temporary posting, or letting your own French main home for up to four months a year.

A further trap caught even careful owners: the tourist classification of the flat does not replace the town-hall authorization. In 2024 the Cour de cassation quashed a Bordeaux appeal judgment that had treated an official meublé de tourisme classification as dispensing the owner from change-of-use authorization, recalling that: « Selon le deuxième, toute personne, qui enfreint les dispositions de l’article L. 631-7 ou qui ne se conforme pas aux conditions ou obligations imposées en application de cet article, est condamnée à une amende civile. » (Court of Cassation, 3rd Civil Chamber, 27 June 2024, No. 23-13.131). Do both procedures in the right order: classification for the tourist label, authorization for the change of use, and registration where the municipality requires it. Fines for unlawful change of use can reach 25,000 euros per property under Article L.651-2 of the construction and housing code, with the proceeds paid to the municipality, so Paris and other strained cities actively pursue cases, including against owners living abroad.

B. Filing, paying and challenging the assessment

File every year even when the French tax seems small. Non-residents declare French rents on the standard income return with the property supplement for unfurnished income or the professional supplement for BIC, and the administration’s current guidance points unfurnished owners to return 2044 and furnished owners to the BIC sections. Owners claiming the EEA or Swiss exemption from CSG and CRDS tick boxes 8SH or 8SI of return 2042 C, and unfurnished owners in the single-exempt-spouse situation also complete box 8RF with the exempt amount, leaving the 7.5 percent solidarity levy to apply on the balance. From the September after filing, instalments for the following year are computed on that basis. Keep foreign proof of social-security affiliation ready: the exemption is checked, not granted on a bare tick.

Pay attention to three recurring filing mistakes. First, declaring gross rents net of the agent’s commission: the commission is a charge to deduct under the régime réel or to ignore under the flat allowances, never a reduction of the declared gross. Second, mixing personal-occupation months into the rental computation without the comparison-rent logic: periods when you or your family occupied the flat produce no rent but do not erase the property’s taxable capacity, and unexplained gaps invite questions. Third, forgetting the worldwide-rate option under Article 197 A: if your overall income is modest, attach the foreign evidence and claim the average rate instead of suffering the 20 percent floor in silence. Each of these points is cheaper to get right at filing time than to repair after assessment.

When the assessment is wrong, act through the réclamation préalable (prior administrative claim) before any court. Address a reasoned claim to the tax office that issued the notice, identifying the tax, the year, the amount disputed and the legal grounds, with every supporting document attached: leases, invoices, proof of payment, foreign assessments for the worldwide-rate claim, affiliation certificates for the social-levy exemption. The administration has six months to answer; silence for six months counts as an implicit rejection that opens the door to the administrative court. If the dispute concerns the 20 or 30 percent minimum, frame the claim around the worldwide average rate with full disclosure rather than around fairness alone, since the Conseil d’État has already upheld the mechanism itself. If it concerns disallowed charges, rebuild the invoice trail charge by charge, because the judge taxes only documented expenses.

Court proceedings follow the usual administrative ladder: tribunal administratif (administrative court) first, then the cour administrative d’appel (administrative court of appeal), with the Conseil d’État as final judge. Deadlines are strict, and the prior claim is in most cases the mandatory gateway, so a late or missing claim loses the case regardless of its merits. For large exposures, consider instructing counsel as soon as the audit proposal or the notice arrives rather than after the claim is rejected: the arguments raised in the claim bind the later litigation, and a claim drafted without the decisive exhibit rarely recovers at trial. Keep all returns, notices, leases and invoices for at least the years the administration may still review, and store them where your heirs or agent can find them if you sell or stop letting.

Conclusion

Non-resident ownership of French rental property rewards method, not optimism. Identify your category on day one: unfurnished means property income with the micro-foncier or the régime réel, furnished means business income with BIC accounting and a much lower simplified threshold for tourist lets. Price the minimum 20 percent income-tax floor and the 17.2 or 18.6 percent social levies, reduced to the 7.5 percent solidarity levy only with proven EEA or Swiss affiliation, and test the worldwide average rate before accepting the floor. In regulated cities, clear the change-of-use authorization before the first short-term guest arrives, because the courts treat repeated short lets as a change of use and the tourist classification as no substitute. File completely, tick the right boxes, keep every invoice, and challenge errors through the prior claim within the deadline. Handled this way, a French rental remains what it should be: a productive asset with a known, bounded tax cost. Our Paris real estate practice reviews foreign owners’ rental files, filings and disputes at each of these stages.
