French Tax Residence Test: Are You Domiciled Fiscal in France?

Am I French tax resident? The short answer

French tax residence is decided under Article 4 B of the Code général des impôts, which sets out four alternative tests. They are genuinely alternative: meeting any one of the four makes you French tax resident, and it does not matter that you fail the other three.

The test that catches people out is the household limb. It looks at where your foyer — your spouse or partner and dependent children — is based, not at how many days you personally spend in France. Someone who works abroad for most of the year while their family remains in France is generally French resident under this limb regardless of their own travel pattern. The remaining limbs cover your principal place of stay, your principal professional activity, and the centre of your economic interests, each assessed independently.

How Article 4 B decides French tax residence

Article 4 B is structured as four separate routes into French residence rather than a single combined test. Each is assessed on its own terms, and satisfying just one is sufficient.

Because these limbs operate independently, a full assessment has to work through all four rather than stopping at the first one that seems favourable. Someone who is confident they fail the day-count test can still be caught by the household or economic interests limb without realising it.

The household test: why your family's address matters more than your own diary

The foyer limb is assessed on where your household is permanently established, not on your own presence. If your spouse or partner and dependent children habitually live in France, that limb is satisfied on its own, independently of anything else.

This is the provision that most often produces a surprising result. A common pattern is a professional who takes an assignment abroad while their spouse and children remain in France, typically for schooling or continuity. The travelling partner may track their own days carefully and stay well below any threshold that feels significant, yet remain French tax resident throughout because the household itself never left — personal presence simply is not part of the analysis once a French foyer is established.

Only where there is no spouse, partner or dependent child does the household limb fall away, leaving the principal place of stay as the relevant alternative under the same paragraph of Article 4 B.

Principal place of stay, professional activity and economic interests

Where there is no French foyer, the first limb falls back to the lieu de séjour principal — your principal place of stay. This is usually evidenced by spending more than 183 days in France, but the underlying test is comparative: it is satisfied wherever you spend more time in France than in any other single country, which can be established even below that figure.

The professional activity limb looks at where you carry on your principal activity. Where someone has more than one activity, the principal one is whichever takes up most of their working time or, if that is unclear, whichever generates the majority of their income. Passive management of your own investments does not count as a professional activity, so an investor living partly in France is not drawn into this limb through portfolio activity alone.

The economic interests limb is assessed differently again. It looks at where your principal investments and business assets are located and from where you administer your affairs — the location of the interests themselves, rather than where you personally happen to be when managing them. A fourth, narrower limb applies only to French state employees posted overseas and not taxed on their worldwide income by the host country.

What French tax residence means for your income and wealth

Once you are French tax resident under any limb, you are taxable on worldwide income at progressive rates, subject to the quotient familial, France's household-based system for calculating the applicable rate.

A distinction that regularly catches people out is that social charges — prélèvements sociaux — are levied separately from income tax. They apply to investment income at 17.2%, on top of the progressive income tax charge rather than instead of it. Anyone who has modelled their position using only the headline income tax rate is liable to find their actual combined liability materially higher once social charges are added.

French residents holding assets abroad also carry an annual declaration obligation, covering foreign bank accounts, investment accounts and life assurance policies. This is a reporting requirement rather than a tax charge in itself, but it carries fixed penalties per account that apply independently of whether any French tax was actually due. Missing a declaration on an account with no tax consequence at all can still trigger a penalty.

Two further charges apply more narrowly. French residents owning worldwide real estate above 1.3 million euros fall within the impôt sur la fortune immobilière, France's property wealth tax; non-residents remain within its scope on their French property only. Separately, France applies an exit tax to substantial shareholdings on transfer of residence abroad, a provision aimed specifically at residents who might otherwise realise gains free of French tax shortly after leaving.

Domicile fiscal is not the same as UK or Irish domicile

The French term for tax residence under Article 4 B is domicile fiscal, and the wording routinely misleads readers with a UK or Irish background. In both of those jurisdictions, domicile is a distinct and longer-term legal concept, generally tied to origin and long-term intention, and separate from residence.

Domicile fiscal is not that. It is a residence concept, assessed under Article 4 B for each tax year on the criteria set out above, and has no relationship to UK or Irish domicile rules. Being non-domiciled in the UK sense carries no weight in the French analysis, and UK advisers occasionally import assumptions from UK domicile law that simply do not transfer. Where a person is being assessed under both French and UK or Irish rules, the two questions need to be kept entirely separate.

Non-resident taxation in France

Where none of the four limbs is satisfied, you are treated as a non-resident, taxable in France only on French-source income — French rental income, gains on French property, and French employment income.

Non-resident taxation carries its own minimum rates: 20% on income up to a threshold and 30% above it, applied automatically unless you can demonstrate that your worldwide income would attract a lower average French rate. That demonstration is not applied for you — it is a claim that has to be made actively, typically by disclosing your full worldwide income to establish the comparison, and it is easy to overpay by assuming the lower rate applies without making the claim.

Compliance caveat

This page and its accompanying tool address the four limbs of Article 4 B on the facts you supply. They do not assess treaty tie-breakers where another country also claims you as resident, the impatriate regime for inbound employees, the computation of exit tax on substantial shareholdings, the detailed calculation of IFI, or French succession rules. Where two countries both treat you as resident, the applicable tax treaty's tie-breaker provisions decide which claim prevails, and that analysis is best completed before your first French filing rather than in response to an enquiry.

How Global Investments can help

French residence turns on tests that assess your household, your work and your economic interests independently, so a position that looks safe on one measure can still fail on another. Our advisers work with clients across more than 60 countries to review which limbs of Article 4 B apply, model the effect of a planned move before it happens, and coordinate with French tax specialists where a treaty tie-breaker needs to be argued.
