Key Takeaways
- A French ski property carries three recurring annual taxes for a non-resident owner: taxe foncière (the ownership tax), taxe d'habitation sur les résidences secondaires (THRS, the second-home occupancy tax), and, above a value threshold, the impôt sur la fortune immobilière (IFI, the real-estate wealth tax).
- Taxe d'habitation was abolished for principal residences only, fully from 1 January 2023. It remains in force for second homes, which is what almost every overseas buyer owns.
- Eligible communes can add a THRS surcharge (majoration) of 5% to 60% on the communal share. In 2025, 1,628 communes applied one and around 657 voted the maximum 60%.
- Cadastral bases rise by a flat +0.8% in 2026 regardless of any local rate vote. The long-promised national revaluation has been deferred again, to around 2031.
- IFI applies only where net French real estate exceeds €1.3 million on 1 January. Once liable, the calculation reaches back to €800,000, and there is no 30% discount on a second home.
- All three taxes use a 1 January snapshot, but the trigger differs: ownership for taxe foncière, use or occupancy for THRS, and net French real-estate value for IFI. French tax is country-specific and changes; confirm your position with a notaire or tax adviser.
The three taxes you pay to hold a French ski home
Owning a French ski property carries three recurring taxes each year, before any rental income, capital gains or succession question arises. One is for owning the bricks: taxe foncière. One is for keeping the property as a second home: taxe d'habitation sur les résidences secondaires (THRS), often surcharged in Alpine resorts. One is a wealth tax that applies once the value is high enough: the impôt sur la fortune immobilière (IFI).
This article covers the annual cost of holding the property. If you are new to the wider tax position on an overseas ski home, our guide to tax basics for overseas ski property owners covers rental income tax, capital gains on sale and double-taxation treaties, which sit outside this article's scope.
Each tax is assessed on your position on 1 January: who owns the property, how it is occupied, and what it is worth. The figures and rules below reflect the position as of 2026 and are intended as orientation, not a substitute for professional advice.
Taxe foncière: the tax for owning the property
Taxe foncière is the annual local tax on whoever owns the property on 1 January of the tax year.1 It is payable whether the property is occupied, vacant or let. The base is the valeur locative cadastrale (VLC, the cadastral rental value), a theoretical annual rent set by the tax authority rather than the market rent.
For built property the net taxable base is the VLC reduced by a flat 50% abatement (abattement forfaitaire), which accounts for theoretical owner costs such as management, insurance and upkeep.1 The final bill is that net base multiplied by the rates voted by the commune and intercommunalité. Because rates are set locally, there is no useful national average bill: the only reliable method is to check the specific commune.
The bill also carries ancillary lines. The taxe d'enlèvement des ordures ménagères (TEOM, the household waste charge) is payable even if you use the flat for only a few weeks each winter, and a landlord letting the property can in most cases recover the TEOM portion from a tenant. The taxe pour la gestion des milieux aquatiques et la prévention des inondations (GEMAPI, a flood-prevention surtax) may also appear as a small additional local line; check the commune notice.
A new build, including an off-plan (vente en l'état futur d'achèvement, VEFA) purchase, can qualify for a two-year exemption from taxe foncière after completion. This is not automatically a full exemption: the commune or intercommunalité can suppress it or reduce it to a partial exemption. Check the exact local policy before relying on it.
Notices are typically issued in early autumn, around September, with an online payment deadline near 20 October. Bills over €300 must be paid electronically, and non-residents can opt for an annual payment or a ten-month direct debit.
The silent annual drift
A stable local rate does not mean a stable bill. Cadastral bases are revalued each year by a flat indexation, set at +0.8% for 2026, following +1.7% in 2025, +3.9% in 2024 and +7.1% in 2023.2 Your bill can therefore rise with no local rate vote at all.
The long-promised national revaluation of cadastral values has been deferred again under the 2026 Finance Act, with first effective application now expected around 2031.3 Today's bases still rest on decades-old reference data, so for now only the modest annual indexation applies.
Taxe d'habitation on second homes (THRS): the tax most buyers think was abolished
Taxe d'habitation sur les résidences secondaires (THRS) is the tax most overseas buyers assume no longer exists. The reform that abolished taxe d'habitation removed it for principal residences only.
Abolished for main homes only
Taxe d'habitation was abolished for principal residences, fully from 1 January 2023. The official position is that the reform does not apply to second homes.4 A non-resident's ski apartment or chalet is a résidence secondaire by default, so THRS applies to almost every overseas buyer.
Liability falls on whoever has use of the furnished second home and its dependencies on 1 January. The base is the same VLC used for taxe foncière, but with one important difference: there is no abatement at all.4 THRS is computed on the full gross VLC, so the same property is taxed on a larger base for THRS than for taxe foncière.
The scope extends to non-adjoining dependencies such as a private parking bay, a garage or a ski locker, even where unheated or unfurnished. A property left genuinely empty and unfurnished is outside THRS, though depending on zoning it may instead face the taxe sur les logements vacants (the tax on vacant dwellings). Notices typically issue in November, with payment due by around 15 December.
The second-home surcharge (majoration): up to 60% extra in Alpine resorts
On top of THRS, eligible communes can vote a surcharge known as the majoration, under Article 1407 ter of the Code général des impôts. The surcharge ranges from 5% to 60% and applies to the communal share of the tax.4 It is available to communes in zones tendues, areas with a marked imbalance between housing supply and demand and a high concentration of second homes.
Adoption is widespread and concentrated in the mountains. In 2025, of 3,690 eligible communes, 1,628 applied a majoration (44.1%, up from 39.5% in 2024), and around 657 of those, roughly 40%, voted the maximum of 60%.5 The national average majoration was 41.4%. Auvergne-Rhône-Alpes, the main French Alps region, had the most communes applying it at 339, ahead of Provence-Alpes-Côte d'Azur at 327.
Eligibility expanded sharply toward mountain and tourist hubs. In the Alps the eligible communes include 127 in Savoie, 108 in Haute-Savoie, 83 in Hautes-Alpes and 60 in Isère.10 Eligibility is the right to vote the surcharge, not the rate itself, so an eligible commune may apply nothing.
The driver is budgetary. After the abolition for main homes reduced municipal income, the surcharge is a restorative tool, and some mayors also use it to push "cold beds" (lits froids, second homes left empty most of the year) back into the local rental market. According to the official DGFiP/DGCL local-finances bulletin, municipal revenue from the surcharge reached €436 million in 2024, up 52% on 2023.9
No official current grid of per-resort rates exists. With around 657 communes already at the 60% maximum and a national average of 41.4%, Alpine resort communes commonly sit at the higher end of the 5% to 60% range, but the rate is set commune by commune and can change each year. The reliable approach is to check the live rate for the exact commune using the official local-tax comparison tool.6
Staying compliant: the occupancy declaration and the €150 fine
Owners of French property, including non-residents, must declare each property's occupancy status, main home, second home, let or vacant, through the "Gérer mes biens immobiliers" (GMBI, "Manage my properties") service on the tax portal. Once filed, the declaration only needs updating when the occupancy status changes.
The €150-per-property fine
For 2026, you must update the GMBI declaration by 1 July 2026 where occupation changed between 2 January 2025 and 1 January 2026.7 Failure to update, or an inaccurate or incomplete declaration, carries a fine of €150 per property, with higher penalties for bad faith or fraud.
THRS has only narrow exemptions, granted on application to the local tax office. They cover cases such as a second lodging required for work, certain cases where the owner has moved into long-term care, a property that is structurally uninhabitable or under renovation exceeding 25% of its value, and certain classified tourist lets in rural revitalisation zones. These are exceptions rather than the norm, and most overseas owners will not qualify; confirm any claim with your tax office.
IFI: the wealth tax that catches higher-value chalets
The impôt sur la fortune immobilière (IFI) is a wealth tax on real estate, which replaced the old impôt de solidarité sur la fortune (ISF) in 2018. It taxes property only: liquid assets, equities, bank deposits and similar holdings are excluded. A non-resident is taxed solely on French-situated real estate, including French property held indirectly through company shares such as a société civile immobilière (SCI, a French property-holding company), to the extent of the underlying French property value.8
The €1.3m threshold and the €800k trap
You are liable only if your net taxable French real estate exceeds €1.3 million on 1 January. At or below that figure, the IFI is nil. Once you cross €1.3 million by even a small margin, the progressive scale applies from €800,000, not only on the amount above €1.3 million.8
There is also no 30% discount on a second home. The 30% valuation reduction applies to a principal residence only, so a non-resident's ski home is assessed at 100% of its open-market value on 1 January.
The 2026 scale is unchanged from 2025 and is marginal, so each band applies only to the portion of value that falls within it.
| Net taxable real-estate assets | Marginal rate |
|---|---|
| Up to €800,000 | 0% |
| €800,001 to €1,300,000 | 0.50% |
| €1,300,001 to €2,570,000 | 0.70% |
| €2,570,001 to €5,000,000 | 1.00% |
| €5,000,001 to €10,000,000 | 1.25% |
| Over €10,000,000 | 1.50% |
A décote smooths the cliff for estates between €1.3 million and €1.4 million. It is calculated as €17,500 minus 1.25% of net taxable wealth, then deducted from the raw liability.8
Take a net taxable estate of €1,350,000. The first €500,000 above the €800,000 entry point is taxed at 0.50% (€2,500), and the remaining €50,000 above €1,300,000 at 0.70% (€350), giving a raw liability of €2,850. The décote is €17,500 minus 1.25% of €1,350,000 (€16,875), which is €625. The net IFI is therefore €2,850 minus €625, or €2,225.
For British buyers, many non-real-estate assets sit outside IFI and do not count toward the €1.3 million threshold. Pensions, wrappers and assurance-vie holdings should be checked with a tax adviser. Valuations are self-assessed, so the position should be confirmed before filing.
Managing the IFI base: debt, mortgages and SCI
Because IFI is charged on net value, debt that genuinely relates to the French property can reduce the base. To be deductible, a debt must exist on 1 January and be directly linked to the property. Deductible items typically include a bank mortgage registered against the French property, outstanding building or maintenance invoices, the taxe foncière itself, and the theoretical IFI liability.
Several common debts are not deductible. These include taxe d'habitation, income taxes and social charges, a mortgage secured on UK or other foreign assets unless it is formally registered against the French property, and family or shareholder loans that lack arm's-length commercial terms. A registered French mortgage can be relevant to the IFI base, but deductibility depends on how the debt is secured and documented; our guide to French mortgages for non-resident buyers covers how these are arranged.
Interest-only (in fine) loans face a specific restriction. For IFI, the deductible amount is amortised straight-line over the term, so on a €1 million ten-year in fine loan the full €1 million is deductible in year one, around €600,000 in year five, and nil in year ten, even though no capital has been repaid. A large-estate cap also applies: where gross taxable real estate exceeds €5 million and total debt exceeds 60% of that value, the portion of debt above 60% is deductible at only 50%.
Holding through an SCI affects the IFI position too. An SCI may affect valuation, but any discount should be adviser-led, evidenced and reviewed before completion, and a shareholder loan from the buyer or family to the SCI (a compte courant d'associé) is not deductible for IFI. The succession and forced-heirship uses of an SCI sit outside this article; our guide to inheritance tax and succession planning for ski property buyers covers those, and given the rule-bound nature of deductibility the structure should be reviewed with a notaire or tax adviser before completion.
The non-resident's tax year: key dates
The three taxes follow a predictable annual rhythm, all anchored to a 1 January snapshot, though the trigger differs: ownership for taxe foncière, use or occupancy for THRS, and net French real-estate value for IFI. The pattern below reflects the typical calendar; confirm the exact dates each year.
Ownership, occupancy and value are fixed on this date for all three taxes. Your position on 1 January determines what you owe for the year.
If liable, file Form 2042-IFI. Where you have no French income return, add Form 2042-IFI-COV and tick box 9GN. The 2026 online deadline is staggered by département of residence, from 21 May to 4 June 2026; non-residents without a French fiscal address generally file by the latest date, 4 June 2026.
Update the GMBI declaration only if occupancy status changed in the previous year. The €150-per-property fine applies for failure to update or for an inaccurate declaration.
The IFI notice is typically issued in August, with payment due around 15 September. Amounts over €300 must be paid online.
The taxe foncière notice typically arrives around September, with an online payment deadline near 20 October.
The THRS notice typically issues in November, with payment due by around 15 December.
Frequently Asked Questions
Wasn't taxe d'habitation abolished?
It was abolished for principal residences only, fully from 1 January 2023. It remains in force for second homes, which is what almost every overseas ski buyer owns, so THRS still applies.
Do I pay THRS if I only use the flat a few weeks a year?
Yes. Liability depends on having use of the furnished second home on 1 January, not on the number of nights you spend there. Even ancillary spaces such as a ski locker or parking bay fall within scope.
My commune said rates were stable, so why did my bill rise?
Cadastral bases are revalued each year independently of any local rate vote, by +0.8% for 2026. Add-on lines such as TEOM and GEMAPI also sit on the same notice, so the total can rise even when the headline rate does not.
Is my ski apartment caught by IFI?
Only if your net French real estate exceeds €1.3 million on 1 January. Once you are over that threshold, the calculation runs from €800,000, and there is no 30% second-home discount. Confirm your valuation with a tax adviser.
Do I get the 30% main-home discount on IFI?
No. The 30% valuation reduction applies to a principal residence only. A non-resident's ski home is a second home, so it is assessed at 100% of its open-market value.
What is the €150 fine?
It is the penalty for failing to update the GMBI occupancy declaration when status changes, or for filing an inaccurate or incomplete one. The fine is €150 per property, with higher penalties for bad faith or fraud.
