Does Owning a Second Home in France Make You a Tax Resident?

For British buyers considering a ski chalet or alpine apartment, one question surfaces repeatedly in every initial consultation: will purchasing property in France automatically render one a French tax resident? The short answer, reassuringly, is that simple ownership of a second home does not, on its own, make you a French tax resident. The longer answer is more nuanced — because French tax residency depends on a set of factual tests that look at where you live, where your economic interests sit, and how many days you spend in France, and a buyer who is not careful about their pattern of use can accidentally tip themselves into French tax residency without intending to.

This guide is written specifically for UK-resident buyers who own, or are planning to buy, a second home in the French Alps and want a clear, practical understanding of the tax residency framework. We’ll cover the four French tax residency tests (the ‘four-corner’ rule published in Article 4B of the Code général des impôts), the widespread but incorrect ‘183-day rule’ that dominates casual discussion, the protective effect of the UK-France double tax treaty, the practical day-counting advice that matters most, and the specific scenarios in which buyers are most at risk of accidentally triggering French tax residency. Everything is current as of April 2026.

A critical preliminary note: this article is general information, not personal tax advice. French tax residency determinations depend on specific facts and should be reviewed with a qualified French tax adviser or an international tax firm familiar with both UK and French rules. Domosno works alongside specialist tax advisers who support our buying clients when complex situations arise — particularly those involving significant time in France, cross-border employment, or the specific case of British pensioners splitting their time between the UK and the French Alps. The Domosno team can make introductions if the question matters to your personal situation.

French tax residency is governed by Article 4B of the Code général des impôts (CGI), which sets out four distinct tests. You are considered a French tax resident for French domestic purposes if any one of the four tests is satisfied — not all four, just one. Understanding this is essential because many buyers assume there is a single rule (usually the incorrect 183-day rule) and miss the fact that French tax residency can be triggered by other factual patterns even when the day count is modest.

Test one: foyer or principal place of residence. Your foyer is where your family home is — the place where you habitually live with your spouse and children. This is the dominant French test and it is based on stability and habituality, not a simple day count. If your spouse and children live permanently in the UK and your French property is used by the whole family for ski holidays, the foyer remains in the UK. If, conversely, you are unmarried and your French property is the only home you actually use habitually, the foyer test could flip you to France even with only moderate French day counts.

Test two: principal place of stay. This is the test that is commonly (and incorrectly) described as the 183-day rule. The French test is actually more subtle: it asks whether you spend more time in France than in any other single country during the calendar year. If you split your year 150 days in France, 140 days in the UK, 75 days in Switzerland and elsewhere, France is your principal place of stay even though you are under 183 days in any one country. Buyers who split their time across multiple countries should therefore plan carefully — 150 days in France can be enough to trigger this test if no other country reaches that count.

Test three: professional activity. If your principal gainful professional activity is carried out in France — as employee, self-employed or as a director of a French company — you are a French tax resident under this test regardless of day count or foyer. For most British second-home buyers this test is not triggered because they continue to work in the UK. It becomes relevant for buyers who take on French consultancy work, become directors of French rental companies, or start businesses in France connected to their property.

Test four: centre of economic interests. This is the test of where your assets and investment income are predominantly located. For a buyer with €2M of UK property and investment assets plus a €600,000 French second home, the centre of economic interests remains in the UK. For a buyer who has sold their UK home, moved substantial savings into a French account, and holds the French property as their only significant asset, the test may look very different. This test is fact-specific and is usually the one that becomes relevant for people who have effectively relocated to France but are trying to avoid formal residency acknowledgement.

The ‘183-day rule’ has entered British expatriate folklore as the definitive test for French tax residency, and it is almost entirely wrong as a statement of French domestic law. The 183-day figure appears in two different places — one relevant, one not — and the conflation of the two has caused endless confusion. First, Article 15 of the UK-France double tax treaty uses 183 days as a test for taxation of short-term employment income: a UK-resident employee working temporarily in France is not subject to French income tax on that employment if they spend fewer than 183 days in France in any twelve-month period and meet other conditions. That is a narrow treaty provision about employment income, not a general residency test.

Second, some other countries (notably some US states and certain other common-law jurisdictions) do use a 183-day test as the primary residency criterion, and expatriate circles have casually translated this into a supposed French rule. France does not use 183 days as its residency test. The French rule is the four-test framework in Article 4B described above, with the ‘principal place of stay’ test looking at comparative days across countries rather than an absolute 183-day threshold.

The practical implication for buyers is that managing to spend fewer than 183 days in France is not, on its own, sufficient protection against French tax residency. A British buyer who spends 150 days in France, 120 days in the UK and the remainder travelling may well find that France is their principal place of stay under test two. Conversely, a buyer who spends 200 days in France but whose family, professional activity and economic interests are firmly in the UK may be able to demonstrate non-residency because the other tests point elsewhere — particularly the foyer test. The framework is not reducible to a single day count.

For Domosno clients who want a safe heuristic rather than a full factual analysis, the conservative guideline is: keep your French days clearly below 120 per calendar year, maintain a strong UK family foyer, and keep your professional activity and economic interests firmly UK-based. This combination puts you comfortably outside French tax residency under all four tests. If you want to spend more than 120 days a year in France, you should take specific personal advice from a cross-border tax specialist rather than relying on general guidance.

The second critical piece of the framework is the UK-France double tax treaty, signed in 2008 and currently in force. Even if the French domestic tests would classify you as a French tax resident, the treaty provides ‘tie-breaker’ rules that allocate residency to one country or the other for treaty purposes — avoiding the worst-case scenario of being treated as a resident of both countries simultaneously and paying full tax to each.

The treaty tie-breakers are applied in sequence. First, permanent home — you are treaty-resident in the country where you have a permanent home available. If you have permanent homes in both the UK and France, you proceed to the second test: centre of vital interests, which looks at where your personal and economic ties are closest. If that is inconclusive, the third test is habitual abode. If still unresolved, the fourth test is nationality. If all four are inconclusive, the two tax authorities negotiate a mutual-agreement resolution.

For most British buyers the treaty tie-breakers resolve in favour of UK residency because the first test — permanent home — treats a second home used for holiday purposes differently from a primary residence used habitually by the family. The French Conseil d’État and the UK tribunals have both confirmed that a property that is effectively a holiday home, not a principal residence, does not on its own constitute a ‘permanent home’ for treaty purposes. This is the core legal reason why owning a second home in France does not, on its own, make you a French tax resident for treaty purposes.

Even as a full UK tax resident, owning a French second home exposes you to several specific French taxes that need to be understood and planned for. First, taxe foncière — the annual property ownership tax levied by the local commune. Rates vary but expect €500–€2,500 per year for a typical ski apartment, with higher figures for larger chalets. The tax is payable by the owner regardless of residency status.

Second, taxe d’habitation sur les résidences secondaires. The main residence taxe d’habitation has been abolished for French primary residences, but second homes remain subject to it, and in high-demand ‘zones tendues’ (which includes most French ski resorts), communes can apply a surcharge of up to 60%. Expect a further €500–€2,500+ per year depending on the property and the commune. This tax has drawn significant press attention in the UK because of the surcharge mechanism, and buyers should model it explicitly in their ownership cost base.

Third, rental income tax, if you rent the property. Rental income generated in France is taxed in France first under the furnished rental (BIC / LMNP) regime, which offers substantial deductions for depreciation, mortgage interest, management fees and running costs and is typically more favourable than UK letting income tax treatment. The UK-France treaty credits French tax paid against the corresponding UK liability, so you do not pay double tax — but you do need to file returns in both jurisdictions. Our buying process guide explains the rental tax mechanics and our French mortgage calculator models post-tax yield expectations.

French inheritance tax (droits de succession) is a separate issue from income tax residency and applies to French-situs assets regardless of the owner’s residency. If you own a French property, French inheritance tax can apply to that property on your death even if you are and remain a UK tax resident. This is one of the most misunderstood aspects of French second-home ownership and deserves specific attention.

The headline French inheritance tax rules for a direct lineal descendant (child inheriting from parent) include a €100,000 allowance per beneficiary, with tax rates rising from 5% to 45% depending on the amount inherited above the allowance. For a £600,000 ski apartment inherited by a single child, the tax can be in the order of €60,000–€80,000 depending on the exact value and whether debts can be deducted. For inheritances outside the direct line (nieces, nephews, unmarried partners, step-children) the rates are significantly higher and the allowances much smaller.

A range of planning tools exists to mitigate French inheritance tax exposure: holding the property via a Société Civile Immobilière (SCI) in some scenarios, using French-law démembrement (splitting ownership between usufruit and nue-propriété), structuring mortgage debt to reduce the taxable base, and choosing UK law under the EU Succession Regulation via a formal election. These are sophisticated planning areas and should be addressed at the buying stage with specialist advice — retrofitting a structure after the property is acquired is often much more expensive than getting it right at the outset. Domosno’s buying process includes a standard conversation about inheritance planning, and we introduce clients to specialist advisers where the family situation warrants it.

To make the framework concrete, consider five common scenarios. Scenario one: the classic ski-holiday buyer. Couple based in London, two children in UK schools, both working in UK jobs, buying a 2-bed ski apartment used 4–5 weeks per year with the rest of the year let out. UK tax residency is unchanged, French tax residency is not triggered under any of the four tests, and the tax picture is limited to French taxe foncière, taxe d’habitation secondaire, and rental income tax (with treaty credits) on the let weeks.

Scenario two: the part-year pensioner. Retired British couple with grown children, UK state pension plus small private pensions, buying a chalet and spending 5 months per year in France, 6 months in the UK, 1 month visiting children elsewhere. The day count in France (around 150 days) could trigger the principal place of stay test if France is the single largest country. Careful planning matters: maintain a UK foyer, keep UK GP registration, retain UK bank accounts as primary, and consider whether deliberately swinging to French tax residency (which has some pension tax advantages under the treaty) might actually be preferable.

Scenario three: the cross-border consultant. UK-resident consultant who takes on project work with French clients and uses the French property as a base during French work periods. The professional activity test becomes directly relevant. This scenario requires specific professional advice before purchase because accidentally triggering French residency through work pattern can have meaningful tax consequences.

Scenario four: the eventual relocator. British buyer who intends to move to France permanently in 3–5 years and buys now with that in mind, initially using the property for holidays. The initial tax position is the standard UK-resident second-home owner, but the purchase structure should anticipate the eventual move — particularly the choice of whether to buy via SCI, which is a more flexible structure for someone planning to change residency, versus direct ownership, which is simpler for a pure holiday home.

Scenario five: the unmarried partner case. Two unmarried partners jointly buying a French second home while both remaining UK residents. The ownership structure, inheritance tax treatment, and treaty residency position all differ materially from the married-couple equivalent. This is an area where specific structuring advice is particularly valuable, because French inheritance tax treats unmarried partners much more harshly than married couples and the planning opportunities are significant but fact-specific.

Before buying, take specialist advice if your situation is anything other than the simple ski-holiday-buyer scenario. For the standard case, Domosno’s standard buying process includes the key tax and inheritance conversation points built into the client consultation, and we introduce clients to cross-border tax specialists when the situation warrants. The cost of getting the structure right at the outset is typically £1,500–£3,500 in advisory fees; the cost of fixing a wrong structure later can be multiples of that.

After buying, keep good records. Specifically: track your French and UK days carefully (a simple calendar spreadsheet is sufficient), retain utility bills and receipts proving UK habitual residence, keep your French bank account separate from your UK arrangements, and file both French rental returns (if applicable) and UK self-assessment returns accurately. If you become a UK HMRC statutory resident because of your day count or other factors, flag the French ownership in your UK return via the Foreign pages, and declare the rental income and the foreign property assets as required.

If circumstances change — you retire, you start spending more time in France, you take on French work, you marry a French national — revisit the tax position with a specialist. French residency is a sliding scale of factual exposure, not a binary switch, and many British buyers find that a conversation with a cross-border specialist every 3–5 years identifies planning opportunities (or risks) that would otherwise be missed. The Domosno team maintains relationships with several respected UK-France tax specialists and can make introductions at any point in the ownership journey.
