Window

Calendar year

Also triggers

Effect

Worldwide income taxed

Basis

CGI Art. 4 B

France treats you as a tax resident if any one of four tests is met — and spending more than 183 days in France in a calendar year is the usual sign of one of them (your main place of stay). But your foyer (household), your main professional activity, or the centre of your economic interests being in France each makes you resident on its own, regardless of day count. Residency creates liability on your worldwide income.

Who it applies to

This matters most if you are:

• A remote worker, digital nomad, or frequent traveler spending long stretches in France.
• Someone whose spouse or children live in France while you work or travel abroad.
• An entrepreneur or investor whose main business, assets, or income sit in France.
• An expat moving to or from France mid-year, unsure which country taxes that year.

It applies to individuals regardless of nationality — French residency is about your home, presence, work, and economic ties, not citizenship or visa status.

The rule — and why it exists

The criteria come from Article 4 B of the Code général des impôts (CGI). You are a French tax resident if any single one of these applies:

• Foyer (household). Your permanent home or family household is in France — typically where your spouse and children habitually live, even if you personally travel for work.
• Main place of stay. France is where you spend the most time. Spending more than 183 days in France is the practical proxy for this test.
• Professional activity. Your principal occupation or business is carried out in France (unless it is only ancillary to activity elsewhere).
• Centre of economic interests. France is where your main investments, assets, or source of income are located or managed.

Why it exists: countries use where you live, where you spend time, where you work, and where your money is as proxies for where your economic life truly sits. The four-pronged test stops people avoiding residency purely by counting days while keeping a home, a job, or their wealth in France.

Counting the days

1. 1Add up every day you are physically present in France during the calendar year (1 January to 31 December).
2. 2Any day you set foot in France generally counts, including partial arrival and departure days.
3. 3The count resets to zero at the start of each new calendar year — it is not a rolling 12-month window.
4. 4More than 183 days is the customary proxy for having your main place of stay in France, one of the four Article 4 B tests.
5. 5Because it is only a proxy, staying under 183 days lowers risk but does not override the foyer, professional-activity, or economic-interest tests.

The 183-day figure is a practical benchmark rather than a hard statutory limit. French authorities and courts look at where you actually spend most of your time, so a stay well above 183 days almost always points to residency, while a stay below it is weighed alongside the other criteria.

Examples

Example 1 — clearly resident by days

You rent an apartment in Paris and spend about 210 days in France across the calendar year, more than in any other country. France is your main place of stay, so you are a French tax resident and France can tax your worldwide income for that year.

Example 2 — resident despite few days

You live mostly abroad and spend only ~70 days in France, but your spouse and children live full-time in your house in Lyon. Your foyer is in France, so you are resident under Article 4 B — the low day count does not save you.

Example 3 — resident through your business

You keep your day count under 183 and have no family home in France, but you run your only active business from an office in Bordeaux. Your main professional activity is in France, which makes you resident on that basis alone.

Exceptions & edge cases

• Double-taxation treaties. If you are resident in two countries, the relevant treaty tie-breaker (permanent home → centre of vital interests → habitual abode → nationality) assigns a single treaty residence and divides taxing rights.
• Split-year on arrival or departure. When you move to or from France mid-year, France generally taxes worldwide income only for the part of the year you are resident, and French-source income for the rest.
• Ancillary professional activity. Work carried out in France that is only secondary to a larger activity abroad does not, by itself, make France your principal professional base.
• Couples assessed together. Because the foyer test turns on the family household, spouses are often assessed together, so one partner's home in France can pull in the other.

Common misconceptions

• "Under 183 days means I'm safe." False — a foyer, your main work, or your economic centre in France makes you resident with any number of days.
• "Only French income is taxed." Residency brings worldwide income into scope, subject to any applicable treaty.
• "The four tests all have to be met." No — meeting any one of foyer, main place of stay, professional activity, or economic interests is enough on its own.
• "Not being a French citizen means the rule doesn't apply." Residency is about presence and ties, not nationality or visa status.
