French Capital Gains Tax for Non-Residents in 2026: Rates, Taper Relief, the Loi de Finances 2026 Changes and How to Minimise the Bill When You Sell

If you own a ski apartment or chalet in France and you don’t live there full-time, the rules that govern what happens when you sell are not the same as the rules for French tax residents — and the framework changed meaningfully on 1 January 2026. The Loi de Finances 2026, passed by the French parliament on 20 December 2025, made three specific changes to the non-resident capital gains regime: the social charges rate was raised from 17.2% to 18.6%, the CSG component was increased from 9.2% to 10.6% for income taxed under Article 244 bis A, and the income-tax side of the taper relief was accelerated so that full exemption on income tax is reached after 17 years of ownership instead of 22. Those changes affect every British, Irish and American owner of a French Alpine property who is planning to sell in 2026 or beyond.

This guide walks through the 2026 framework in practical detail. We cover the base rate and headline combined rate for a non-resident seller, the UK and EEA solidarity-levy carve-out that cuts social charges to 7.5%, the abattement (taper relief) schedules for both the income tax and the social charges side, the list of allowable expenses you can add to your acquisition cost to reduce the taxable gain, the principal exemptions (including the €150,000 one-off exemption for former residents and the primary-residence rule) and the mechanics of the fiscal representative that France still requires for higher-value sales. It is written for an ordinary British or Irish owner selling a French Alps apartment or chalet, not for a tax professional, and we have cross-checked every number against the impots.gouv.fr 2026 guidance and the 2026 Bulletin Officiel des Finances Publiques.

The short version is this: for a British owner selling a typical €550,000 Alpine apartment bought in 2013 for €400,000, the headline 2026 capital gains tax bill is roughly €40,000 — substantially less than the €50,000+ most owners fear, because of the UK solidarity-levy carve-out, the taper relief on the income tax portion and the accelerated 17-year taper. Get the structure right, keep the paperwork clean, and the tax on a 12-year Alpine hold is usually very manageable. Get it wrong and the bill can be nearly double.

The headline combined rate for a non-resident selling French real estate in 2026 is 37.6%, made up of 19% plus-value income tax and 18.6% social charges. The income tax element is applied under Article 244 bis A of the CGI (Code Général des Impôts) and is a flat 19% on the net taxable gain — it is not progressive and does not depend on the seller’s other income. The 18.6% social charges are applied on the same net taxable gain and are new as of 1 January 2026: before the Loi de Finances 2026 the rate was 17.2%.

On top of the 37.6% headline rate, sellers whose net taxable gain exceeds €50,000 pay a supplementary surtax (surtaxe sur les plus-values immobilières élevées) that rises from 2% to 6% in steps — reaching the top 6% rate when the net gain exceeds €260,000. The surtax is computed on the same taxable base as the main tax, and it applies to non-residents and residents alike. For most British owners of a mid-market Alpine apartment the surtax is either nil or in the 2–3% band.

The tax is not deducted by the buyer or the notary in the way a UK seller might expect from stamp duty. Instead, the French notaire handling the sale is required to compute, deduct and remit the tax directly to the French Treasury on the day of completion, so what arrives in your bank account is the net-of-tax proceeds. This is non-negotiable and it is the notaire’s legal responsibility. You should see the exact calculation set out in the notaire’s completion statement (décompte) — ask for it in advance if it matters to the post-sale cash planning.

A critical point: the base for the tax is the taxable gain, not the headline profit. The taxable gain is the sale price, minus the acquisition cost, minus allowable acquisition expenses (7.5% flat OR actuals), minus allowable improvement works (15% flat OR actuals if the property has been held more than 5 years), minus the taper relief (abattement pour durée de détention). We work through each of those in the next two sections, because that is where the real planning lives.

If you are affiliated to the UK social security system (or any EEA state or Switzerland) and you are not simultaneously covered by a French social security regime, you benefit from a carve-out on the social charges element. The carve-out was introduced after the 2015 Ruyter judgement at the Court of Justice of the European Union and survived Brexit via specific French legislation in 2019. Under the carve-out, a British seller of French property pays only the 7.5% solidarity levy component of the social charges, not the full 18.6%. The carve-out is automatic but it has to be claimed on the correct line of the notaire’s Cerfa 2048-IMM form on the day of completion.

The effect is substantial. On a €150,000 net taxable gain, the social charges at the full 18.6% are €27,900. At the reduced 7.5% carve-out rate they are €11,250 — a saving of €16,650. Combined with the 19% income tax (€28,500), the total tax burden on the €150,000 gain is €39,750 for a UK seller under the carve-out, versus €56,400 for a seller who is not entitled to the carve-out. This is the single most valuable thing a British owner of a French property needs to know about the 2026 tax framework.

To claim the carve-out you need to supply proof of UK social-security affiliation, typically in the form of a certificate from HMRC or a recent NHS letter, along with a completed Form 2048-IMM filed by the notaire. Some French notaires are unfamiliar with the carve-out for British sellers — it is worth mentioning it explicitly at the first meeting and providing the HMRC certificate up front. Our Domosno buying process guide covers this for every British buyer at the purchase stage so that the paperwork is already in place when the eventual sale happens.

A small caveat: the carve-out applies only to individuals, not to French companies (SCI soumise à l’IS) holding property. And it does not apply to French nationals living in the UK who are still covered by a French social-security regime. The overwhelming majority of British owners of Alpine properties qualify, but it is worth checking with a cross-border tax adviser in the specific case of dual-national owners or retired civil servants with residual French regime coverage.

Taper relief (abattement pour durée de détention) is the single most important tax planning lever for long-term holders of French property, and the Loi de Finances 2026 made a major change here. Until 31 December 2025 the taper on the income tax side reduced the taxable gain by 6% per year from year 6 to year 21, and 4% in year 22, reaching full exemption after 22 years. From 1 January 2026 the schedule has been accelerated: the taper is now 8% per year from year 6 to year 16, and 4% in year 17, reaching full exemption after 17 years.

The social charges taper is unchanged. It still reduces the taxable base by 1.65% per year from year 6 to year 21, by 1.60% in year 22, and by 9% per year from year 23 to year 30 — reaching full exemption after 30 years of ownership. This asymmetry between the 17-year income tax exemption and the 30-year social charges exemption is the main reason that very long holds (20-year and above) can still carry a meaningful tax bill on the social-charges side even after the income tax has been fully tapered away.

The practical impact for a British owner selling in 2026 with 12 years of ownership is meaningful: on the income tax side, the gain is reduced by 8% × 7 years = 56%, so a €150,000 gross gain is taxed on €66,000 at 19%, giving a €12,540 income tax bill instead of the €28,500 it would have been on the full gain. On the social charges side, the gain is reduced by 1.65% × 7 years = 11.55%, so the €150,000 gain is taxed on €132,675 at 7.5% (UK carve-out), giving a €9,950 charge. Total tax: €22,490 on a €150,000 gain — about 15% effective rate.

The taper clock starts at the date of the authentic deed of purchase (acte authentique), not the date of the preliminary contract (compromis or VEFA reservation). For new-build VEFA purchases, the acte authentique is typically signed 24–30 months after the reservation contract, so the effective taper clock is meaningfully shorter than buyers expect. Planning long holds on VEFA purchases is easier if you track the acte date from the start — our French Alps new-build guide explains the chronology.

The second major planning lever is what you can add to the acquisition cost to reduce the taxable gain. French tax law allows four categories: acquisition expenses (notaire fees, agency fees, registration duty), improvement works (travaux), the cost of new equipment installed during ownership that has a useful life longer than one year (extensions, new kitchens, new heating systems), and, in very specific cases, architect and engineering fees associated with those works.

On acquisition expenses you can choose between a flat 7.5% of the purchase price OR actuals. Most buyers should take the flat 7.5% because real notaire fees on a French Alpine resale are typically 7–8% of the price and you would need to produce every single invoice to beat the flat — which, on a property bought 12 or 15 years ago, is rarely possible. The 7.5% flat is automatic and needs no documentation. Take it.

On improvement works the rule is different. If you’ve held the property for more than five years you can choose between a flat 15% of the purchase price OR actual receipted works. The 15% flat is generous and suits owners who haven’t spent much on the property; actual works is the better choice if you have spent more than 15% of the purchase price on works and you have the French TVA invoices (factures) to prove it. Critically, works must have been carried out by a VAT-registered French contractor — DIY and unreceipted cash jobs do not qualify, nor do works that were already included in a VEFA new-build price.

The most common planning mistake is buyers who spend €40,000 or €50,000 on a major kitchen-and-bathroom refit during ownership and then fail to keep the French TVA invoices. Without the factures the tax authorities will reject the actual-works claim and the seller is forced to fall back on the 15% flat — often a smaller figure. Every owner of a French Alpine property should keep every French-contractor invoice in a dedicated folder from the day they take possession. This single discipline often saves €5,000–€15,000 on the eventual sale tax bill.

There are a small number of full or partial exemptions that can dramatically reduce or eliminate the tax bill for specific sellers. The most important for British owners is the exemption for former French residents under Article 150 U-II-2° of the CGI: if you were tax-resident in France for at least two consecutive years at some point before the sale, if you have kept free disposal (libre disposition) of the property since the end of your French residency, and if the sale takes place before 31 December of the tenth year following the end of your French residency, you are entitled to an exemption on the first €150,000 of net taxable gain.

The €150,000 is a person-specific exemption — a couple can claim up to €300,000 combined if both spouses meet the residency test independently. For most ex-pat British owners who lived in France for a working spell before returning to the UK, this exemption is the single biggest tax saving available. It is worth checking the dates carefully because the 10-year post-residency window is hard — day 3,651 is too late. Our French tax advice section covers the interaction with the UK-France double tax treaty.

The primary residence exemption (Article 150 U-II-1°) is in principle available to non-residents, but in practice it requires that the property sold was the seller’s principal residence at the date of the sale — which almost by definition excludes a ski apartment held by a British owner. It can apply in rare cases where the owner has lived full-time at the French property for the final months before the sale, but the French tax authorities look hard at the supporting evidence (utility bills, tax declarations, healthcare registration) and the exemption is routinely refused for convenience claims.

Finally, there is an exemption for sellers whose sale proceeds are used within 24 months to buy or build a French primary residence (Article 150 U-II-1° bis). This is useful for British sellers who are retiring to France and buying a mainland property with the proceeds of an Alpine holiday home. The exemption requires that the seller has not owned a French primary residence at any point in the preceding four years, which is typically easy to satisfy for a pure holiday-home owner. Budget for a year of planning around this exemption if it matches your situation.

Until 2021, every non-EU seller of a French property above €150,000 was required to appoint a French fiscal representative (représentant fiscal) to guarantee the tax payment. The post-Brexit clarification of 2021 extended the exemption from the fiscal representative requirement to EEA countries and confirmed that UK residents were no longer automatically caught. As of April 2026, UK residents are not routinely required to appoint a fiscal representative for sales of French residential property. This is a significant cost saving — fiscal representatives typically charge 0.5–1.0% of the sale price, so on a €550,000 Alpine apartment the saving is €2,750–€5,500.

There is a narrow exception. If the sale price exceeds €150,000 AND the seller is a non-EEA non-resident (US, Canada, Australia, etc.), a fiscal representative is still required. The list of accredited French representatives is published on the impots.gouv.fr site and the notaire handling the sale will usually recommend one. The fee is negotiable for straightforward sales and we recommend getting two or three quotes.

Even when a fiscal representative is not legally required, some French notaires still recommend appointing one on complex sales — for example where the property is held by an SCI, where the acquisition history involves a divorce or inheritance, or where the seller is domiciled in a non-treaty jurisdiction. The cost/benefit of the representative is a judgement call and we suggest asking the notaire to set out the specific risks of not appointing one before taking a decision.

For the overwhelming majority of British owners selling an Alpine ski apartment in 2026, no fiscal representative is needed. The notaire computes the tax, deducts it at completion, files the tax return on the seller’s behalf, and remits the funds to the Treasury. The whole process is handled in one appointment at the notaire’s office. You will walk out with the net proceeds and a copy of the completed 2048-IMM form — keep the latter for your own tax records in case HMRC asks about the foreign gain.

Scenario 1: A British couple bought a €380,000 apartment in Morzine in April 2014, sell it in April 2026 for €540,000. Held 12 years. Gross gain €160,000. Acquisition expenses (7.5% flat): €28,500. Notional works (15% flat, 12 years held): €57,000. Net taxable gain before taper: €74,500. Income tax taper (8% × 7 = 56%): tax base €32,780, income tax at 19% = €6,228. Social charges taper (1.65% × 7 = 11.55%): tax base €65,895, UK carve-out at 7.5% = €4,942. Total tax: €11,170. Effective rate on gross gain: 7%.

Scenario 2: A British owner bought a €600,000 chalet in Les Gets in June 2020 for €600,000, adds €80,000 of receipted TVA works in 2022, sells in June 2026 for €850,000. Held 6 years. Gross gain €250,000 minus €80,000 receipted works = €170,000 taxable before further reliefs. Acquisition expenses (7.5% flat): €45,000. Net taxable gain before taper: €125,000. No taper yet (first taper year is year 6 with 8%): tax base €115,000. Income tax at 19% = €21,850. Social charges UK carve-out at 7.5% = €8,625. Total tax: €30,475. Effective rate on gross gain: 12.2%.

Scenario 3: A British retired couple, both former French residents from 2008–2012, bought a €450,000 Val d’Isère apartment in 2018, sell in 2026 for €620,000. They are still within the 10-year post-residency window (2012+10 = 2022 — actually just out of it). Because the 10-year window expired in 2022, the €150,000 former-resident exemption is no longer available. Standard calculation: gross gain €170,000, acquisition expenses €33,750, taxable before taper €136,250. 8-year hold = 24% income-tax taper, 4.95% social-charges taper: income tax on €103,550 at 19% = €19,675; social charges on €129,506 at 7.5% = €9,713. Total: €29,388. Lesson: if you are a former French resident, TIME the sale to land before the 10-year window closes.

These three worked examples show the range. The effective rate on a 6-to-12 year hold ranges from roughly 7% to 14% of the gross gain, depending on the works receipted, the UK carve-out, the taper schedule and any exemption claimed. This is dramatically less than the 37.6% headline rate that spooks most sellers, and it’s the reason that a properly planned French Alpine sale is usually not the tax disaster people fear. Our French Alps property for sale team works the numbers with every owner we list.
