France Tax Residency: The 183-Day Rule
France does not treat a 183-day count as a standalone domestic tax-residency test. Article 4 B of the Code général des impôts treats you as having a French tax domicile if France is your foyer or place of principal stay, if you carry on your main professional activity there (unless it is ancillary), or if France is the centre of your economic interests. Meeting any one criterion is enough. Tax authorities generally treat more than six months of presence in a year as principal stay, so 183 days is strong evidence on that limb only. A family foyer in France can make you resident while you travel most of the year. Treaties can still assign you to another country after domestic law says yes.
This guide is for remote workers using France as a base, families who leave a partner in Lyon, and people who treat "under 183 days" as a French safe harbour. It is not.
The problem is importing a Spanish-style day rule into article 4 B. Days are a tool for principal stay, and even then they are not absolute.
After this post you can apply the four 4 B ideas, walk a 2026 example, and see what BOFiP actually says about six months.
Key facts
| Fact | Detail |
|---|---|
| Statute | CGI article 4 B |
| Tests | Foyer or principal stay; main professional activity; centre of economic interests |
| 183 days | Usual indicator of principal stay (more than six months), not a separate article |
| One test enough | Any single 4 B criterion can create French tax domicile |
| Consequence | Worldwide income, subject to treaties (CGI 4 A) |

How French tax residency works under article 4 B
The tax administration states that you have your tax domicile in France if one of these is true: you have your foyer there or, failing a foyer, your principal stay; you exercise a professional activity there unless it is ancillary; or you have the centre of your economic interests there. [Source: impots.gouv.fr.]
Foyer. BOFiP describes the foyer as the place where the people concerned normally live, that is their habitual residence, provided it is permanent. It can remain your foyer even if work keeps you elsewhere most of the year, if the family continues to live there. [Source: BOI-IR-CHAMP-10.]
Principal stay. If there is no foyer, principal stay is assessed from actual presence. BOFiP's general rule: people who stay in France more than six months in a given year are treated as having their principal stay there. The same doctrine says six months is not an absolute criterion. The Conseil d'État has found a principal stay where the person spent more time in France than in any other country even without leaning on the six-month line.
Professional activity. Salaried or not, unless you show it is ancillary. Main activity is the one that takes the most actual time, or, if that cannot be applied, the one that produces the largest share of worldwide income. A 2025 change to article 4 B also treats certain directors of large French-headed companies as carrying on their main activity in France unless they prove otherwise.
Centre of economic interests. Where you made your main investments, sit your affairs, administer property, or from which you draw the greater part of your income.
Article 4 B also says that people who meet a domestic criterion are still not treated as French tax residents if a tax treaty does not regard them as residents of France.
Why "the 183-day rule" is the wrong French headline
Nomads like 183 because other countries print it. France prints foyer, stay, work, and money. You can be under 183 days and still be resident through a foyer or an economic centre. You should not plan a French year as "182 days and done." Schengen 90/180 is a different clock. A visiteur visa can make a six-month stay legal and therefore easier to hit. See France visiteur visa explained.
Worked example with 2026 dates
Camille is a Canadian remote designer. Her spouse and child live year-round in a rented flat in Nantes. Camille's 2026 presence in France is 1 February to 15 March and 1 July to 20 August (43 + 51 = 94 days). She spends the rest of the year in Mexico and Canada.
Day count: 94, well under 183, and under six months.
Foyer analysis: the family's habitual home is France. BOFiP's foyer discussion is built for this pattern. Domestic law can still treat Camille as having her tax domicile in France even while she travels. A France-Canada treaty tie-breaker then looks at permanent home and centre of vital interests. That is a treaty question, not a "94 days means safe" question.
Second profile: Sam, single, no French family, no French company. Sam stays in furnished rentals in Paris from 2 January 2026 to 10 July 2026 (190 days) and works only for a US employer. No French foyer. Principal stay is the live issue. More than six months in the year is the BOFiP general rule. Professional activity is not exercised in France as a French job, but presence still supports the stay limb. Sam should not assume non-residence.
Who French residency applies to
It applies to anyone who meets a 4 B test, including EU citizens. Nationality is not the switch. Mixed couples are analysed person by person: one spouse can be resident and the other not. [Source: impots.gouv.fr.] Foreign payroll does not erase a French foyer or principal stay. Non-residents with French-source income sit in a different box, not a hidden 183-day exemption.
Step 1. Locate the foyer before you count days
Ask where you and, if relevant, your spouse or partner and children habitually live. If that answer is France, day counting is secondary.
Step 2. If there is no foyer, measure principal stay
Count 2026 calendar presence. Treat more than six months as the administration's usual line. Also compare time in France with time in any other single country.
Step 3. Test work and economic centre independently
Where do you spend the most working time? Where is the greater part of your income and asset management? Either limb can succeed at low day counts.
Step 4. Only then open the treaty
If France and another country both say resident, read the residence article: permanent home, centre of vital interests, habitual abode, nationality. Do not skip 4 B and jump to the treaty.
How to track French presence without a spreadsheet
France is a poor fit for a single 183-day cell because foyer and economic centre ignore that cell. You still need an accurate day ledger for principal stay and for Schengen if you are a short-stay visitor. Staywise (the visa compliance app for digital nomads) tracks days in France and every other country, including 183-day style thresholds, with 7/3/1-day alerts before stay limits. Passport details stay on your device. Available on iOS.

Common mistakes travelers make
Stopping at 182 days. Foyer and economic centre do not need 183.
Leaving a partner and children in France and calling yourself a nomad. That is the foyer pattern BOFiP describes.
Treating a pied-à-terre as automatically a foyer. A holiday flat you barely use is not the same as the family's habitual home. Facts decide.
Using Schengen 90/180 as a tax plan. Legal presence and tax domicile are different.
Ignoring treaties after a 4 B match. Domestic domicile and treaty residence are stacked, not identical.
Assuming remote work for a foreign company cannot be a French professional activity. Time spent, and income share if needed, still matter.
How France interacts with other tax systems
French tax residents are taxable on French and foreign-source income, subject to conventions. [Source: impots.gouv.fr.] US citizens remain US taxable worldwide. Germany's Wohnsitz test and France's foyer test can both fire if you keep homes in both countries. That is a dual-residence file, not a day-count race. See Germany tax residency: the 183-day rule.
Frequently Asked Questions
Does France have a 183-day tax residency rule?
Not as a free-standing article. Article 4 B uses foyer or principal stay, main professional activity, and centre of economic interests. BOFiP says that, as a general rule, staying more than six months in a year means your principal stay is in France. That is why people quote 183 days. It is an indicator for one limb. You can be resident with fewer days through foyer or economic centre, and six months is not described as an absolute criterion in all cases.
Can I be a French tax resident if I spend fewer than 183 days in France?
Yes. If your foyer is in France, the administration can treat you as domiciled there even when work keeps you abroad most of the year. A centre of economic interests in France can also suffice. Principal stay can sometimes be found from a pattern of presence that is greater than in any other country. Under-183 is not a French non-resident certificate.
What is the foyer for French tax purposes?
BOFiP treats the foyer as the place where you normally live, the habitual residence, if that residence is permanent. For a couple, it is often where the spouse or partner and children live. A second home or occasional rental is not automatically a foyer. The quality of habitual family life matters more than the number of nights you personally slept there in the year.
If a tax treaty says I am not a French resident, does 4 B still matter?
Article 4 B itself says you cannot be treated as having your French tax domicile when, by application of a double-tax convention, you are not regarded as a resident of France. The administration also states that treaty residence prevails over domestic domicile in a conflict. You still start with 4 B, because the treaty tie-breaker runs after two domestic claims. Keep both analyses.
Does a France visiteur visa or remote-work stay decide my tax residence?
No. Those documents decide whether you may stay. Article 4 B decides tax domicile. A long-stay visa can make a six-month presence lawful, which then supports the principal-stay limb. It does not by itself create or erase residency. A visiteur visa with a family still living in France is a foyer fact pattern, not a tourist day count. Count days, locate the foyer, and map economic ties separately.
