Leaving France: the complete tax guide to a clean, optimised departure
Leaving France is not just a move, it is a tax event that, handled well, can be remarkably light, and handled badly, surprisingly costly. From the moment your residence changes, a precise sequence applies: the split year, the exit tax, the purge of latent gains, the French assets you leave behind, and the formalities of departure. This guide walks through the whole departure, step by step and in the right order, so that nothing important is missed along the way.
We cover: how France decides you have left, the split year of departure, what changes when you become a non-resident, the exit tax, purging gains before you go, cryptocurrency, the real estate you leave in France, selling it later, social levies, declaring your departure, French-source income afterwards, treaties, EU vs third-country moves, choosing a destination, bank-account reporting and coming back. With a worked sequence and a checklist, so your departure is planned rather than improvised.
Are you actually leaving?
Everything begins with one question: have you genuinely ceased to be a French tax resident? Under article 4 B of the tax code, you are a resident if any one criterion applies, your home or main place of stay, your main professional activity, or the centre of your economic interests is in France. To leave, all of these must truly move abroad.
A departure that is only partial, keeping your family home, your main job or your economic centre in France, may not end your residence at all. The administration looks at the substance of your life, where you, your family and your economic interests actually are, not at a plane ticket or a foreign address.
Establishing a clean break, and being able to evidence it, is therefore the foundation of leaving France. Everything that follows, the split year, the exit tax, the taxation of your French income, depends on this change of residence being real, deliberate and documented. A break that exists only on paper is the single biggest risk of a departure.
The year of departure: a split year
The year you leave is special. You are treated as a resident for the part of the year before departure, and a non-resident for the part after, split at your date of change. Worldwide income is taxed for the resident period; only French-source income for the non-resident period.
This split makes the timing of income and disposals within that year important. Realising a gain or receiving a bonus just before or just after the change of residence can lead to very different outcomes, since one side of the line is taxed on worldwide income and the other only on French-source income.
Handling the year of departure correctly, the split return, the precise date of change, the sequencing of any income, avoids both double counting and missed opportunities. It is the first technical step of a well-managed departure, and the one that frames every figure on your final resident-year return.
Becoming a non-resident: what changes
Once you are a non-resident, the scope of French tax narrows dramatically: France taxes you only on your French-source income, no longer on your worldwide income. Your foreign salary, your foreign investments and gains realised abroad all fall outside the French net.
In exchange, your French-source income, French rents, French real-estate gains, certain French dividends, salaries for work in France, becomes subject to the specific non-resident rules: the minimum rate of 20/30%, the average-rate option, and particular social-levy rates.
Understanding this shift is the heart of leaving France: from broad worldwide taxation to a narrow French-source base, governed entirely by the non-resident regime and its specific rates. The rest of this guide is about managing that transition cleanly. See the non-resident guide →
The exit tax
If you leave holding a substantial securities portfolio (broadly at least €800,000, or a 50% company stake), the exit tax on unrealised gains may apply. In most cases it is deferred, automatically for a move to the EU/EEA, on request for a third country, and ultimately cancelled if you keep your securities long enough.
Real estate and directly held cryptocurrencies are outside its base. For most people who leave, the exit tax is therefore a reporting obligation rather than a real cost, provided the formalities and any required guarantees are handled correctly at departure.
If you leave with significant holdings, confirming whether the exit tax applies and securing the deferral is an essential step of departure. It is a once-off matter, but not one to overlook. See the exit-tax guide →
The assessment maps your exit tax, the gains to purge and the French assets you leave behind. Plan my departure →
Purging latent gains before you go
One of the most powerful moves is to realise (purge) latent gains at the right moment around your departure. Because a non-resident is generally outside French tax on securities gains realised after leaving, disposals made once you are non-resident can escape French taxation, subject to the exit tax and treaty rules.
Conversely, some gains are better realised while still resident, or deliberately deferred, depending on your destination and its own tax rules. The purge is therefore not a single recipe but a sequencing decision, made in light of both French and foreign taxation.
Getting this sequence right, what to realise before, what to leave until after, is where a departure is genuinely optimised. It rewards planning the move months ahead rather than improvising at the last minute, when the change of residence has already happened and the options have narrowed.
Cryptocurrency before leaving
Cryptocurrency deserves special attention. Directly held crypto is outside the exit tax, and a non-resident is generally outside French tax on crypto gains realised after leaving. For a holder with large unrealised crypto gains, leaving France can therefore be highly efficient.
The key is the same as for securities: the timing of disposals relative to the change of residence, and the rules of the destination country. A move to a country that does not tax crypto gains, made before realising them, can be particularly effective, but only if the change of residence is genuine and the timing is right.
As always, this must be planned in light of both French departure rules and the destination’s regime, rather than assumed. But crypto is one of the assets for which a well-timed departure offers the clearest advantage, precisely because it sits outside the exit tax and outside French tax once you are non-resident.
Real estate left in France
Many people leave France while keeping a property there, often rented out. Rent from that property remains French-source and taxable in France, subject to the minimum rate (with the average-rate option) and to social levies of 17.2% or 7.5% depending on your affiliation.
The choice of regime (micro or actual), the average-rate option and the social-levy rate all continue to apply to your French rents as a non-resident, exactly as for any non-resident landlord. Your French property does not leave the French net simply because you have left the country.
Managing the French rental you leave behind is therefore part of leaving well: the same levers that cut any non-resident’s rental tax, the average-rate option and the reduced social levies, apply equally to you. See the non-resident guide →
Selling French property later
If you later sell the French property as a non-resident, the capital gain is taxable in France at 19% plus social levies, with holding-period allowances that taper the tax to zero after enough years. The social levies can be 7.5% rather than 17.2% for an EEA/Swiss/UK affiliate.
A seller established outside the EEA selling above €150,000 must appoint a fiscal representative, a point that now catches UK residents since Brexit. This is a formality, and a cost of up to around 1% of the price, to anticipate well before signing.
So the property you keep on leaving will, one day, raise its own set of questions, gain, allowances, social levies, representative. Knowing them in advance lets you choose the best moment to sell, often after a holding period that reduces or removes the tax. See the property-sale guide →
Social levies as a non-resident
On your French capital income after leaving, rents, real-estate gains, the social levies are 17.2% in principle, but fall to 7.5% if you are affiliated to a social security scheme in the EEA, Switzerland or the UK. Affiliation, not residence, drives this rate.
This means your destination’s social-security arrangements matter: an affiliate of a European scheme keeps the reduced rate, while an affiliate of a third-country scheme bears the full 17.2%. Where you have overpaid by being charged 17.2% while affiliated in Europe, the CSG-CRDS difference can be reclaimed for the years that are not yet time-barred.
Factoring the social-levy position into your departure, and your choice of destination, is part of the picture. It can make a meaningful difference, year after year, to the tax on the French income and assets you leave behind.
Declaring your departure
Leaving France involves formalities: you inform the tax administration of your change of address abroad, file the split-year return, and your file moves to the non-resident tax office, which handles individuals living abroad. From then on, that office is your interlocutor for French tax.
These steps are not optional housekeeping: they establish your non-resident status with the administration and ensure your French-source income is taxed under the right regime. A clean departure is, in part, a well-declared one.
Handling the declaration properly, the change of address, the split-year return, the transfer to the non-resident office, is what turns a physical move into a recognised change of tax residence. It is the administrative backbone of leaving France, and the step that lets the administration apply the non-resident regime to you rather than continuing to treat you as a resident.
French-source income after leaving
After departure, you continue to declare your French-source income, rents, French salaries for work in France, certain French dividends, French pensions depending on the treaty, to the non-resident tax office, under the non-resident rules. The minimum rate and the average-rate option apply here.
Your foreign income, by contrast, no longer concerns the French administration, except where you declare worldwide income solely to obtain a favourable average rate. The line between French-source (taxed) and foreign (outside the net) becomes the organising principle of your filings.
Keeping this distinction clear, year after year, is what makes life as a French non-resident straightforward: declare the French-source income, apply the right rate, and leave the rest outside the French net. See the non-resident guide →
Tax treaties and your new country
The tax treaty between France and your new country of residence is the master key to your departure. It allocates the right to tax each type of income, sets a single country of residence in case of conflict, and provides the mechanism, credit or exemption, that eliminates double taxation.
In practice, French-source income is taxed in France, and your new country relieves the double charge under the treaty, while taxing your worldwide income under its own rules. Reading the applicable treaty for each category of income is the right reflex, not reasoning in generalities about "how treaties work".
The treaty is what makes two tax systems coherent rather than overlapping. Whenever a French-source income and your new residence meet, it is the document to consult to understand the final outcome.
EU/EEA vs third country
The destination shapes much of the experience. A move within the EU or EEA brings lighter formalities, the automatic exit-tax deferral, reduced social levies for an affiliate of a European scheme, no fiscal representative on a later property sale.
A move to a third country generally offers the same substantive reliefs but with more demanding procedures: the exit-tax deferral on request and possibly with guarantees, the full social-levy rate unless affiliated in Europe, and a fiscal representative for a later non-EEA property sale above the threshold.
None of this makes a third-country move disadvantageous, many of the most attractive destinations are outside the EU, but it does mean the formalities require more anticipation. Knowing which rules apply to your destination is part of planning the departure.
Choosing a destination
Where you go matters as much as the act of leaving. The destination determines your future income-tax environment, the treaty that will govern your French-source income, your social-levy rate, and the exit-tax and representative formalities. A genuinely tax-efficient departure is, in part, a well-chosen one.
Some destinations combine a favourable local regime with a workable treaty and EEA-style social-levy treatment; others offer low local tax but heavier French formalities. The right choice depends on your assets, your income and your plans, including whether you might one day return.
Choosing a destination is therefore not only a lifestyle decision but a tax one, to be made with the full picture in view. It is the point where the whole departure strategy, exit tax, purge, French assets, social levies, treaties, comes together into a single, coherent choice.
Bank accounts and reporting
Leaving France also has a reporting dimension. Foreign bank accounts and the automatic exchange of information between countries (the common reporting standard) mean your financial life abroad is increasingly transparent to tax administrations. Compliance, on both sides, is the safe path.
As a non-resident, your French reporting narrows to your French-source income and assets, while your new country has its own reporting rules for your worldwide situation. Keeping both sets of obligations in order is part of a clean expatriation.
Transparency is now the norm, not the exception. Approaching your departure with correct reporting on both sides avoids problems later and lets you enjoy the genuine, lawful advantages of non-residence without risk. The benefits of leaving are real; they do not require hiding anything.
Coming back later
A departure is often not forever. If you return to France after a genuine period abroad, the impatriate regime may exempt a large part of your income for up to eight years, and it is open to returning French nationals, not only to foreign hires.
This is why a departure should be planned with a possible return in mind: the purge of latent gains on the way out and the impatriate regime on the way back are two sides of the same long-term optimisation. Many returnees overlook the regime and forfeit years of exemption.
Thinking about the return from the moment you leave turns a one-way move into a planned, reversible journey. It is the final piece of leaving France well, and the reason a departure is best designed as a round trip from the very start. See the impatriate-regime guide →
Common mistakes
1. Leaving only partially, keeping home, job or economic centre in France, so residence never ends.
2. Mishandling the split year, mis-timing income around the date of departure.
3. Ignoring the exit tax or failing to secure its deferral.
4. Not purging gains at the right moment relative to departure.
5. Forgetting the French property left behind, its rents and a future sale.
6. Overlooking the impatriate regime on a later return.
Your checklist
To leave France cleanly:
1. Make a genuine break under article 4 B and keep evidence of it.
2. Handle the split year and the timing of income carefully.
3. Check the exit tax and secure its deferral if it applies.
4. Plan the purge of latent gains (securities and crypto) around departure.
5. Manage the French property you keep, rents now, sale later.
6. Declare your departure and move to the non-resident tax office.
7. Read your destination’s treaty and consider a possible return (impatriate).

When am I considered to have left France?
When none of the article 4 B criteria still apply, your home, main activity and economic centre have all genuinely moved abroad. A partial move that keeps one of these in France may not end your French tax residence.
What is the split year of departure?
In the year you leave, you are a resident for the period before departure (taxed on worldwide income) and a non-resident afterwards (taxed only on French-source income). The timing of income around the date of change therefore matters.
Will I pay the exit tax?
Only if you leave with large securities holdings, and even then it is usually deferred and ultimately cancelled if you keep them long enough. Real estate and directly held crypto are outside its base.
What happens to my French property?
Its rents stay taxable in France under the non-resident rules, and a later sale triggers French capital-gains tax with holding-period allowances. A non-EEA seller above €150,000 may need a fiscal representative.
Does my destination matter?
Yes. An EU/EEA move brings lighter formalities (automatic exit-tax deferral, reduced social levies for a European affiliate, no representative on a later sale); a third-country move offers similar reliefs with heavier procedures.
What if I come back to France?
The impatriate regime may exempt much of your income for up to eight years on return, and it is open to returning French nationals. Planning the return from the outset is part of leaving well.
