France 183-day rule: what digital nomads and expats get wrong

France is the world's most visited country. It also has one of the most misunderstood tax residency tests. The belief that "under 183 days means you are safe" is wrong. French domestic tax law contains no standalone 183-day threshold. What it contains is three independent triggers. Any one of them can make you a French tax resident before you reach 183 days.

The three triggers in Article 4B CGI

French tax residency is governed by Article 4B of the Code Général des Impôts (CGI). You are a French tax resident if you meet ANY ONE of three criteria.

Criterion 1: foyer or principal place of stay. This criterion has two sub-tests. If your spouse or dependent children live permanently in France, France is your "foyer" (habitual household). That alone makes you a French tax resident regardless of how many days you personally spend in France. No day count required.

If you have no family foyer in France, the fallback is "lieu de séjour principal" (principal place of stay). France is your principal place of stay if you spend more days in France than in any other single country. This is a relative test, not an absolute one.

Criterion 2: professional activity. If you carry out salaried or self-employed professional activity in France, and that activity is not merely ancillary to a main activity abroad, you are a French tax resident. Senior executives of French-registered companies with annual turnover above €250 million are presumed to work mainly in France unless they can prove otherwise.

Criterion 3: center of economic interests. If your principal investments, main business operations, or the bulk of your income are located in France, you are a French tax resident. This catches property investors with significant French rental income.

The 183-day myth

There is no autonomous 183-day rule in French domestic law.

The "lieu de séjour principal" test works by comparison. If you spent 150 days in France, 120 days in the United States, and 95 days in the United Kingdom last year, France is your principal place of stay. Not because 150 exceeds any fixed threshold. Because 150 exceeds your time in any other single country.

That means you can be a French tax resident while spending fewer than 183 days in France.

The 183-day figure appears in certain bilateral double tax treaties (DTAs) as a proxy at the "habitual abode" step of the tie-breaker cascade. That is a different context. The number in a DTA does not import a day threshold into domestic French law.

What unlimited tax liability means

Once you are a French tax resident under any one of those three criteria, France taxes your worldwide income. Employment income, self-employment income, foreign rental income, dividends, interest, capital gains, and pensions.

Non-residents pay tax only on French-source income. A minimum 20% withholding rate applies, or your actual marginal rate if that is higher.

2025 income tax bands (for 2025 income, filed in 2026):

• 0% up to approximately €11,497
• 11%: approximately €11,497 to €29,315
• 30%: approximately €29,315 to €83,823
• 41%: approximately €83,823 to €180,294
• 45%: above €180,294

French residents also pay social charges (CSG, CRDS) at 17.2% on investment income. A flat tax (PFU) of 30% combines both income tax and social charges on investment income. You can elect the progressive scale instead if it produces a lower rate.

For HNW residents with real estate holdings above €1.3 million, the IFI wealth tax applies. That calculation needs a specialist.

Two systems running at the same time: Schengen and tax

For non-EU nationals entering France on short-stay visa-free access, the Schengen 90/180 rule is the binding constraint before any tax analysis applies.

You can spend at most 90 days across all 29 Schengen countries in any rolling 180-day window. You cannot legally spend 183 days in France without a long-stay visa or a French residence permit. The immigration cap stops you before the tax threshold becomes relevant.

Since April 10, 2026, the Entry/Exit System (EES) records every non-EU short-stay crossing at all Schengen borders digitally. France, including Paris CDG and the Eurostar Channel Tunnel crossing, is an EES border. Your French entry and exit dates are now logged automatically.

For EU nationals and non-EU nationals with long-stay visas or residence permits, there is no Schengen short-stay cap. For them, Article 4B is the relevant constraint.

Schengen immigration law and French tax law run simultaneously. They are completely independent systems. Staying legally under 90 Schengen days tells you nothing about your French tax residency status.

The 2025 treaty override: a new protection

The French Finance Law for 2025 (loi n° 2024-1744 du 30 décembre 2024) amended Article 4B in a meaningful way. Since January 1, 2025: if a bilateral DTA allocates sole tax residence to the other contracting state, France cannot treat you as a French tax resident even if you meet one or more Article 4B criteria.

If you are a UK or US resident and your DTA with France assigns sole residence to your home country under the tie-breaker cascade, French unlimited tax liability does not apply. You remain liable only on French-source income as a non-resident.

This makes getting the DTA tie-breaker right more consequential than it was before 2025.

Year of departure: how the tax year splits

If you leave France partway through the year, France applies split-year treatment.

From January 1 to your departure date, you file Form 2042 as a French tax resident reporting worldwide income. From your departure date to December 31 of the same year, you file Form 2042-NR for French-source income only, at the minimum 20% non-resident rate.

The French tax authority can challenge your claimed departure date if your ties to France continued after you left. Clear documentation of lease termination, address changes, and asset transfers matters here.

Exit tax: the long-term resident trap

If you were a French tax resident for at least 6 of the last 10 years and you leave, France may apply an exit tax on unrealized gains.

The asset thresholds: securities valued above €800,000 at departure, OR a shareholding above 50% in a company. If you hit either trigger, the gain is treated as if you sold everything the day you left. No actual sale is required.

For departures within the EU or EEA, deferral is automatic. For departures elsewhere, deferral requires guarantees. The maximum deferral period is 15 years. You file Form 2074-ETD in your departure year and Form 2074-ETS annually while deferral is active.

The 2025 Finance Law also extended the French tax authority's audit window for false domiciliation from 3 years to 10 years.

UK non-dom context: what changed in 2025

The UK domicile reform came into effect on April 6, 2025. UK IHT moved from domicile-based to residence-based: long-term UK residence is now defined as 10 years in any 20-year period, with the full model applying from April 6, 2026.

For UK HNW nomads who previously used non-dom status alongside careful France exposure management, the planning picture shifted. The UK and French systems are now both residence-based, which reduces the structural divergence that previously created planning opportunities.

The France-UK DTA remains in force. The tie-breaker cascade still applies: permanent home, then centre of vital interests, then habitual abode, then nationality.

Before your next France stay: four questions

1. Is your family household permanently based in France? If yes, you may already be a French tax resident under the foyer test.
2. Are you spending more days in France than in any other single country? If yes, France may be your principal place of stay.
3. Do you carry out professional activity or hold significant investments in France? Either alone can trigger residency.
4. Does a DTA between your home country and France apply, and does it allocate sole residence to your home country?

If you answered yes to any of the first three, or you are unsure about the fourth, talk to a French tax advisor before your next stay.

FAQ

Does spending under 183 days in France mean I am not a French tax resident? Not necessarily. French domestic law uses a relative presence test: France is your principal place of stay if you spend more days there than in any other single country. You can be a French tax resident with fewer than 183 days in France. The foyer and professional activity triggers operate entirely independently of any day count.

What is Article 4B CGI? Article 4B of the Code Général des Impôts is the domestic French statute that defines tax residency. It has three independent criteria: foyer or principal place of stay, professional activity in France, and center of economic interests in France. Meeting any one criterion establishes unlimited French tax liability on worldwide income.

I have a double tax treaty with France. Does it protect me? Since January 1, 2025, yes. If the DTA allocates sole tax residence to your home country under the tie-breaker, French domestic criteria no longer establish French residency. The tie-breaker still requires analysis in order: permanent home, centre of vital interests, habitual abode, nationality.

Does the Schengen 90-day rule affect my French tax residency? No. The Schengen 90/180 rule is immigration law. French tax law operates independently. For non-EU nationals on short-stay access, the Schengen cap prevents a 183-day France stay from being legally possible without a visa, so the immigration constraint binds before the tax question arises.

How does France's exit tax work if I leave? If you were a French tax resident for at least 6 of the last 10 years and hold securities above €800,000 or more than 50% of a company, France applies exit tax on unrealized gains at departure. Deferral is automatic for moves within the EU or EEA. Outside the EU/EEA, deferral requires bank guarantees or pledges.
