# 2026 French Property Tax and Legal Changes: What Non\u2011Resident Owners Need to Know<\/p>\n
More French property law changed in the eighteen months to mid\u20112026 than in the previous decade. The 2026 Finance Act (*Loi de finances pour 2026*), enacted on 19 February 2026, introduced a package of fiscal measures that touches every non\u2011resident owner, from the second\u2011home declaration deadline to new rental investment schemes. At the same time, several landmark rulings by the Cour de cassation have reshaped the boundaries of seller liability, builder warranty and co\u2011ownership enforcement.<\/p>\n
This article maps the most significant tax and legal developments that foreign owners \u2014 whether British, American, Australian or other non\u2011EU nationals \u2014 need to factor into their French property decisions in the second half of 2026.<\/p>\n
## I. The 2026 Finance Act: Key Tax Changes for Non\u2011Resident Property Owners<\/p>\n
### A. Social Charges, Wealth Tax and the Property Declaration Requirement<\/p>\n
**Social charges on furnished rental income rise to 18.6%.** The Social Security Financing Act for 2026 (*LFSS 2026*, law no. 2025\u20111403 of 30 December 2025) increased the CSG component on *revenus du patrimoine* from 9.2% to 10.6%. The headline rate for non\u2011resident landlords receiving furnished rental income (*location meubl\u00e9e non professionnelle*, or LMNP) therefore moved from 17.2% to **18.6%**, effective on 2025 income declared in 2026. Unfurnished rental income (*revenus fonciers*) and capital gains on property sales remain at the older **17.2%** rate. For an owner generating \u20ac10,000 of net furnished rental profit, the increase represents approximately **\u20ac140 per year** in additional social charges, recurring annually.<\/p>\n
**The *Imp\u00f4t sur la Fortune Immobili\u00e8re* (IFI) \u2014 French wealth tax on real estate \u2014 remains unchanged.** A parliamentary proposal to broaden the tax into a “tax on unproductive wealth” that would have captured yachts, art and digital assets alongside real estate was withdrawn during the budget debate. The threshold stays at **\u20ac1.3 million** of net real estate value. Non\u2011residents continue to be liable for IFI only on their French\u2011situs property (not their worldwide holdings), which preserves a meaningful structural advantage for those whose main residence and investment properties lie outside France.<\/p>\n
**The *G\u00e9rer mes biens immobiliers* (GMBI) declaration: the 1 July 2026 deadline.** All property owners \u2014 resident or not \u2014 must confirm or update the occupancy status of each French property via the *biens immobiliers* section of their personal space on impots.gouv.fr. The deadline is **1 July 2026**. Owners who do not yet have a *num\u00e9ro fiscal* (French tax number) should apply for one well before that date. The declaration is **not annual for everyone**: it is required only if the occupancy status of a property changed between 2 January 2025 and 1 January 2026, if you failed to update it last year, or if you have never declared that property. Failure to file attracts a **\u20ac150 fine per property**. The information feeds directly into the calculation of *taxe d’habitation* on second homes and the vacant\u2011housing tax.<\/p>\n
**Taxe fonci\u00e8re: modest base increase for 2026.** The annual nationwide revaluation coefficient applied to cadastral rental values is **+0.8%** for 2026, confirmed by INSEE on 28 November 2025 \u2014 a sharp drop from +1.7% in 2025 and +3.9% in 2024. This figure is the floor. Each *commune* may still vote its own rate on top. Separately, a DGFiP verification campaign is updating “comfort elements” (running water, heating, bathrooms) missing from cadastral records that sometimes date to the 1970s, affecting an estimated 7.4 million dwellings at an average of roughly \u20ac63 per dwelling. The broader cadastral\u2011value reform has been postponed by three years: the new values will now feed into the 2031 tax bases rather than 2028, determined as of 1 January 2028.<\/p>\n
### B. Vacant Housing Taxes, Capital Gains and the New Jeanbrun Investment Regime<\/p>\n
**A unified vacant\u2011housing tax from 2027.** Starting in 2027, the current dual system \u2014 the annual tax on vacant dwellings (*taxe annuelle sur les logements vacants*, TLV) and the council tax on vacant dwellings (*taxe d’habitation sur les logements vacants*, THLV) \u2014 is replaced by a single **taxe sur les locaux d’habitation vacants**. The new tax is payable on dwellings vacant on 1 January of the tax year, provided they have been unoccupied for at least **one year** in a *zone tendue* (a municipality with a significant housing supply\/demand imbalance) or **two years** outside such zones.<\/p>\n
The rates are steep. For vacant dwellings in a *zone tendue*, the tax rate is **17% to 30%** in the first year of taxation and **34% to 60%** from the second year onwards, all levied on the property’s cadastral rental value. Outside *zone tendue*, the tax is optional for municipalities, with a maximum rate of 50%. A foreign owner with a Paris pied\u2011\u00e0\u2011terre that remains empty for a calendar year should expect a significant bill arising from this regime, and should seek to either occupy the property, let it, or sell it before the 2027 entry\u2011into\u2011force.<\/p>\n
**Capital gains: the *amortissement* recapture for furnished\u2011letting sellers.** One of the most consequential changes for investors selling furnished property was introduced by the 2025 Finance Act (article 84, confirmed by *R\u00e9ponse Mette*, QE no. 10097, JOAN 24 March 2026). For sales completed on or after **15 February 2025**, depreciation (*amortissement*) previously deducted while renting the property under the *r\u00e9gime r\u00e9el* is now **subtracted from the acquisition price** when calculating the taxable capital gain. Depreciation taken before 2025 is also caught.<\/p>\n
The gain remains taxed under the private capital\u2011gains regime: **19% income tax + 17.2% social charges = 36.2%** before allowances. If an owner deducted \u20ac80,000 of depreciation over the holding period, the taxable gain rises by that same \u20ac80,000, adding approximately **\u20ac29,000** in tax \u2014 though the holding\u2011period taper survives: full income\u2011tax exemption at 22 years and full social\u2011charge exemption at 30 years.<\/p>\n
**New *statut du bailleur priv\u00e9* (dispositif Jeanbrun): an amortisation break for unfurnished rentals.** The feared abolition of LMNP amortisation did not occur. Instead, the 2026 Finance Act created a new “private landlord” status available for acquisitions (or building permits obtained) between 21 February 2026 and 31 December 2028. An eligible landlord may amortise up to **80% of the property’s value** against rental income over a minimum commitment period of 9 years, with annual amortisation rates of 3.5% to 5.5% for new\u2011build and 3% to 4% for renovated properties, capped at **\u20ac8,000 per year per property** (raised to \u20ac10,000 for social\u2011rental and \u20ac12,000 for very\u2011social\u2011rental use, with a limit of two properties per taxpayer). The property must be rented unfurnished as a primary residence, with the rent capped at approximately 15% below market rates and the lease commencing within 12 months of completion or acquisition. Non\u2011residents qualify, provided they have French\u2011source rental income against which to apply the deduction.<\/p>\n
**Transfer duties (DMTO): departmental rate now up to 5%.** Under the 2025 Finance Act, *d\u00e9partements* may raise their share of transfer duty from 4.50% to a maximum of 5.00% for deeds signed between 1 April 2025 and 31 March 2028. As of 2026, **88 of 101 d\u00e9partements** apply the 5.00% rate, pushing the global notaire\u2011fee percentage on existing property (*ancien*) from approximately 5.81% to 6.32%. On a \u20ac400,000 resale purchase, the extra 0.5\u2011point adds approximately \u20ac2,000. First\u2011time buyers who have not owned a principal residence in the preceding two years are exempt from the surcharge. New\u2011build purchases (VEFA<\/a>) are unaffected.<\/p>\n ## II. Protecting Your French Property: Recent Case Law Shaping the Legal Landscape<\/p>\n ### A. Hidden Defects, Seller Disclosure and the Right to Cancel a Sale<\/p>\n The French Civil Code provides one of the most powerful remedies available to a purchaser: the guarantee against hidden defects (*garantie des vices cach\u00e9s<\/a>*). Article 1641 states:<\/p>\n > \u00ab Le vendeur est tenu de la garantie \u00e0 raison des d\u00e9fauts cach\u00e9s de la chose vendue qui la rendent impropre \u00e0 l’usage auquel on la destine, ou qui diminuent tellement cet usage que l’acheteur ne l’aurait pas acquise, ou n’en aurait donn\u00e9 qu’un moindre prix, s’il les avait connus. \u00bb<\/p>\n In practical terms: the seller must warrant the property against hidden defects that make it unfit for its intended use, or that would have caused the buyer either not to purchase it or to pay a lower price.<\/p>\n Article 1642 sets an important boundary: \u00ab Le vendeur n’est pas tenu des vices apparents et dont l’acheteur a pu se convaincre lui\u2011m\u00eame. \u00bb The seller is not liable for defects that were visible and that the buyer could have discovered through a reasonable inspection. A foreign buyer who visits a property twice before signing and notices nothing unusual about the wall coverings does not necessarily lose the protection of Article 1641: the Cour de cassation has made it clear that the question is whether the buyer could have perceived not just the symptom (wrinkled wallpaper) but the underlying structural defect.<\/p>\n A decision of the Third Civil Chamber on **21 December 2023 (Cass. 3e civ., 21 Dec 2023, no. 22\u201121.518<\/a>)** illustrates these dynamics. The buyer of a house discovered fissures and cracks after removing wallpaper that had concealed them. The sale contract contained a clause excluding the seller’s warranty for hidden defects \u2014 a common provision in French property transactions between private individuals. The Court of Appeal had enforced that clause because the seller, a non\u2011professional who had inherited the property only six months before signing the sale mandate and had never lived there, was held not to have known of the structural disorder. The Cour de cassation upheld that finding on the *vices cach\u00e9s* claim. However, it quashed the same judgment for a different reason: the Court of Appeal had failed to consider whether the simple mention of a “grenier” (attic) in the sale deed implied that the attic was usable \u2014 and whether the seller’s delivery obligation under Article 1602 of the Civil Code had therefore been breached, since that article provides that **any obscure or ambiguous clause is interpreted against the seller**.<\/p>\n The practical lesson is twofold: a seller who is genuinely unaware of a hidden defect may escape liability under a valid exclusion clause, but the obligation to deliver conforming property is broader and does not depend on the seller’s knowledge.<\/p>\n An action under the *vices cach\u00e9s* regime must be brought within a strict time limit. Article 1648 of the Civil Code provides:<\/p>\n > \u00ab L’action r\u00e9sultant des vices r\u00e9dhibitoires doit \u00eatre intent\u00e9e par l’acqu\u00e9reur dans un d\u00e9lai de deux ans \u00e0 compter de la d\u00e9couverte du vice. \u00bb<\/p>\n The two\u2011year window runs from the date the buyer discovered the defect, not the date of sale. A buyer who notices structural issues in the third year of ownership may still be within time. This rule is critical for foreign owners who visit irregularly and may not observe a defect until a later stay.<\/p>\n ### B. Builder Liability, Energy Performance and Co\u2011Ownership Disputes<\/p>\n **The *garantie d\u00e9cennale<\/a>*: a major shift in the scope of builder liability.** The ten\u2011year builder warranty under Article 1792 of the Civil Code holds any *constructeur* strictly liable to the owner for damage that compromises the solidity of the work or renders it unfit for its purpose. The scope of that warranty was significantly recalibrated by the Cour de cassation in a decision published in the Bulletin and the Annual Report: **Cass. 3e civ., 21 Mar 2024, no. 22\u201118.694<\/a>**.<\/p>\n The Court explained that since 2017 it had extended the *garantie d\u00e9cennale* to cover an element of equipment \u2014 even one merely added to an existing building \u2014 if the disorder affecting the equipment rendered the entire work unfit for its purpose. The 2024 ruling **reversed that line of authority**. The Court held that an element of equipment installed by replacement or addition to an existing building does **not** constitute an *ouvrage* (a “work”) and therefore falls **neither under the *garantie d\u00e9cennale* nor the *garantie biennale de bon fonctionnement***, whatever the gravity of the resulting damage. Instead, such a claim is governed by the ordinary law of contractual liability, which is not subject to the compulsory builder’s insurance regime.<\/p>\n The reasoning was candid: despite the earlier extension, the intended protection had not materialised because installers of such equipment do not subscribe to compulsory builder’s insurance, and the owners had access to other insurance cover anyway. For a foreign buyer acquiring a renovated French property, this ruling means that a defective retrofit \u2014 a fireplace insert, a heat pump, photovoltaic panels bolted onto a barn roof \u2014 cannot be pursued under the *garantie d\u00e9cennale* against the installer. The installer may still be sued under the ordinary law of contract and tort, but the automatic ten\u2011year cover and the *assurance dommages\u2011ouvrage* that normally accompanies it will be unavailable.<\/p>\n **The *garantie d\u00e9cennale* and energy performance: a high threshold for liability.** A separate ruling shows that the *garantie d\u00e9cennale* is not automatically engaged by poor thermal insulation. In **Cass. 3e civ., 23 Oct 2025, no. 23\u201118.771<\/a>**, the seller of a house he had partly built was sued by the buyers over inadequate insulation that made certain rooms unusable in winter “without incurring significant energy costs.” The Court of Appeal had found the seller liable under the *garantie d\u00e9cennale* on the basis of the *impropri\u00e9t\u00e9 \u00e0 destination* (unfitness for purpose). The Cour de cassation quashed that finding, holding that under Article L. 111\u201113\u20111 of the Construction and Housing Code, **unfitness for purpose based on energy performance requires proof that the defects lead to energy overconsumption allowing use of the building only at an exorbitant cost**. The lower court had failed to make that finding. An owner seeking to recover the cost of reinsulating a French holiday home from the original builder should be aware that the legal threshold is higher than it may appear: not every cold room or high heating bill triggers the ten\u2011year warranty.<\/p>\n **Co\u2011ownership charges: the syndicat’s power to recover arrears from absent owners.** Two recent decisions confirm the robust tools available to a *syndicat des copropri\u00e9taires* (co\u2011ownership association) when a lot owner \u2014 including a foreign non\u2011resident \u2014 falls behind on charges. On **16 April 2026 (Cass. 3e civ., 16 Apr 2026, no. 24\u201121.820<\/a>)**, the Cour de cassation validated a judgment ordering a copropri\u00e9taire to pay **\u20ac1,275** in outstanding charges plus **\u20ac300** in damages to the syndicat. On **9 July 2026 (Cass. 3e civ., 9 Jul 2026, no. 24\u201121.792<\/a>)**, published in the Bulletin, the Court confirmed that a *syndicat* acting through its provisional administrator could recover unpaid charges through legal proceedings, even when the governance of the co\u2011ownership itself was in difficulty. The amounts at stake in these cases \u2014 from a few thousand to nearly \u20ac40,000 in some related judgments \u2014 show that the French courts treat co\u2011ownership debt as a serious and enforceable obligation. A foreign owner who returns to a locked apartment or a court summons after a year away will find the French legal system unforgiving on this point.<\/p>\n
