The French exit tax explained: who pays, how much, and why it is usually never paid

The French "exit tax" sounds frightening, a tax simply for leaving France. In reality, it is almost always deferred, and most often never actually paid. But it must be reported correctly at departure, and a handful of situations make it bite. Here is exactly how it works, who it concerns, what it covers, and how the deferral and cancellation mechanisms turn it, in most cases, into a formality.

This guide covers: what the exit tax is, who is concerned, what falls in its base and what is excluded, the payment deferral, when the tax is cancelled, when it really becomes due, the special case of apport-cession gains, the reporting obligations, the difference between leaving for the EU or a third country, and tax treaties. With a worked example and a checklist, so you know exactly where you stand before you leave.

What the exit tax is

The exit tax (article 167 bis of the French tax code) taxes the unrealised capital gains on certain securities you hold when you transfer your tax domicile out of France. The idea: France wishes to tax the gain that built up while you were a French resident, even though you have not actually sold the securities yet.

Crucially, it is a tax on latent gains, gains on paper, not yet realised. That is why the law pairs it with a deferral and a cancellation mechanism: in most cases, you do not pay at departure, and you never pay at all if you keep your securities long enough.

Understanding the exit tax means understanding this logic of "tax now in principle, but deferred and usually cancelled in practice". For the great majority of people who leave France, it is a reporting obligation rather than a real cost, provided the deferral is secured and the annual formalities are respected over the years that follow.

Who is concerned

The exit tax concerns individuals who were French tax residents for at least six of the ten years preceding their departure, and who hold securities above certain thresholds. It does not apply to short-term residents, nor to those whose securities holdings fall below the thresholds, broadly €800,000 in value, or a 50% stake in a company. Below those thresholds, the ordinary exit tax does not bite, though the apport-cession rule can still apply regardless of size.

The thresholds: your securities must represent an overall value of at least €800,000, or a holding of at least 50% of a company’s profits. Below these, ordinary departures are not caught, with one important exception, the apport-cession gains under a prior deferral, covered further down, which are caught on departure whatever the size of your holdings.

So the typical person concerned is a long-term French resident leaving with a substantial securities portfolio or a significant company stake. Confirming whether you cross the thresholds, and whether any apport-cession gain is involved, is the first step of any exit-tax analysis, and the point where many departures are wrongly assumed to be outside the regime.

What is in the base

The base of the exit tax is the unrealised gain on your securities, shares, company stakes and similar holdings, measured at the date of departure: the difference between their value then and their acquisition cost. On this latent gain, the tax combines income tax (the flat rate or the progressive scale) and social levies.

The rate is therefore comparable to what you would pay on a real disposal: broadly the flat tax of 30% (12.8% income tax plus 17.2% social levies), or the progressive scale if more favourable. The difference is that here, nothing has actually been sold: the gain is purely on paper, which is precisely why the deferral and cancellation mechanisms exist.

This is the figure that is computed and "frozen" at departure, then placed under deferral. It represents the potential tax, the amount that would become due only later, and only if the cancellation conditions are ultimately not met.

What is excluded

Two important categories fall outside the exit tax base. Real estate, directly held property, is not concerned: you can leave France owning French or foreign property without the exit tax touching it. And cryptocurrencies held directly are likewise outside its scope.

This is decisive for many profiles. A crypto investor, in particular, can leave France with a fully-loaded wallet without any exit tax on the latent gains, one reason expatriation to a low-tax country is so effective for digital assets, where the exit tax simply does not apply.

Knowing what is excluded reframes the exit tax: it is a tax on substantial securities holdings, not a general toll on wealth. Real estate and directly held cryptocurrencies simply are not in its field, which is why a portfolio weighted toward real estate or directly held crypto can fall largely outside the exit tax, an asset-allocation point worth knowing before a move.

The payment deferral (sursis)

The heart of the mechanism is the payment deferral. If you move to a country of the EU or the EEA (with an appropriate administrative-assistance arrangement), the deferral is automatic: you report the gain, but pay nothing at departure. For a move to a third country, the deferral is generally available on request, sometimes subject to providing guarantees.

The deferral means the computed tax is suspended, not collected. It hangs over the securities, waiting to see whether you will sell them or hold them through the cancellation period. In the meantime, you owe nothing in cash at the moment of departure: the tax is computed and reported, but its payment is suspended, which is what makes a clean departure manageable even with a large latent gain on the books.

This is why leaving France with securities rarely costs anything immediately: the deferral, automatic or granted, postpones the tax. The only practical effort, for a third country, may be arranging the required guarantees. See the non-resident guide →

Deferral: automatic or on request

The deferral does not work the same way everywhere. When you move to a State of the EU or EEA (with an appropriate administrative-assistance arrangement), the deferral is generally automatic: you do not have to provide guarantees, and the tax simply sits in suspense.

When you move to a third country, the deferral must usually be requested, and it may be conditioned on providing guarantees to the Treasury, a security covering the deferred tax. There are limited exceptions, but as a rule the third-country route is more demanding and needs to be arranged before departure.

This distinction is one of the most important practical points of the whole regime: the same unrealised gain, the same taxpayer, but a markedly heavier formality depending on the destination. Knowing which regime applies to your move, and preparing the request and any guarantee in advance, is essential. See the Dubai guide →

When the tax is cancelled

The deferral can turn into outright cancellation (dégrèvement). If you keep your securities beyond a defined holding period after your departure, the exit tax on those still-held securities is cancelled, you never pay it. The required holding period depends on the size of the portfolio: the larger the holding, the longer you must keep the securities for the cancellation to apply. Smaller positions reach cancellation sooner than very large ones.

In other words, for someone who leaves and simply holds their securities for long enough, the exit tax evaporates. The latent gain is never actually taxed by France, even though the gain was computed and reported back at the time of departure.

This is the reason the exit tax is, in most cases, "never paid": deferred at departure, then cancelled once the holding period passes. It is the patient holder, not the quick seller, whom the mechanism rewards, a logic worth keeping in mind when planning any post-departure disposal.

Death and gifts during the deferral

What happens to the deferred exit tax if circumstances change while it is suspended? On the taxpayer’s death, the deferred exit tax is, in principle, cancelled: it is not transmitted as a charge to the heirs. The latent gain that justified the tax disappears with the original holder.

A gift of the securities can also cancel the deferred tax, though specific anti-abuse conditions apply, particularly for moves to third countries, to prevent the regime being used purely to escape the charge. The treatment of a gift therefore depends on the circumstances and the destination.

These mechanisms matter for estate and gift planning: a holder under exit-tax deferral should factor in how death or a gift interacts with the suspended tax, rather than treating the exit tax as a fixed future liability. It is a suspended, conditional charge, and several events can extinguish it.

When it actually becomes due

The exit tax becomes genuinely payable in one main case: if you sell the securities before the cancellation period elapses. Selling early ends the deferral and crystallises the tax on the latent gain that had been frozen at departure.

Certain other events can also bring the deferred tax to charge. The practical lesson is that the timing of any disposal, relative to your departure and the holding period, is what determines whether the exit tax stays a formality or becomes a real cost.

Planning the sale of post-departure securities around the cancellation period is therefore central. Hold long enough, and the tax disappears; sell too soon, and it falls due on the frozen gain.

A worked example

Thomas leaves France for Portugal (an EU country) holding a securities portfolio worth €1,200,000, on which the latent gain is €700,000. At departure, the exit tax on that gain is computed, roughly €210,000 at the flat rate, but the deferral is automatic: he pays nothing.

He simply reports the gain, requests nothing special (the EU deferral being automatic), and follows up annually. He keeps his portfolio beyond the cancellation period; the exit tax is then cancelled in full. Had he sold a year after leaving, the same €210,000 would have fallen due. The difference between a formality and a real cost came down to timing, and to handling the reporting correctly.

Apport-cession gains (150-0 B ter)

One important exception to the thresholds: a gain placed in deferral under the apport-cession regime (article 150-0 B ter) enters the exit tax regardless of its amount, without benefiting from the €800,000 or 50% thresholds that apply to other securities.

This matters greatly for company founders and directors who have contributed their shares to a holding company before a sale. If they then leave France, the deferred apport-cession gain is within the exit tax even if it is below the general thresholds.

Anyone who has carried out an apport-cession and is contemplating departure should therefore obtain a dedicated analysis: the interaction of the two deferrals, apport-cession and exit tax, is technical and unforgiving of improvisation, and can turn a well-built structure into an unexpected charge if mishandled.

Reporting obligations

Even when nothing is paid, the exit tax carries reporting obligations. You declare the latent gains and request the deferral on the dedicated form in the year of departure, and you then provide an annual follow-up for as long as the deferral runs, until the tax is cancelled or paid.

These formalities are not optional: missing them can jeopardise the deferral and the eventual cancellation. The exit tax is "free" only if the paperwork is handled correctly, year after year, until the holding period closes the matter.

For most people, then, the real work of the exit tax is administrative rather than financial: report the gain at departure, follow up each year, and let the cancellation mechanism quietly do the rest over the holding period. See your situation →

The annual follow-up

The exit tax is not a one-off form at departure. While the tax is deferred, the taxpayer generally has an annual follow-up obligation: a yearly declaration confirming that the securities are still held and that the conditions of the deferral remain met. Missing it can jeopardise the deferral.

This ongoing reporting is the counterpart of the suspension: the administration keeps track of the deferred gain year after year, until the tax is either cancelled (after the holding period, or on death) or triggered (on a disposal). The obligation runs for as long as the deferral lasts.

For the taxpayer, the practical lesson is that leaving France with an exit-tax position creates a multi-year administrative commitment, not just a single departure formality. Keeping up with the annual declarations is what preserves the deferral and, ultimately, the cancellation. See the leaving-France guide →

Leaving for the EU vs a third country

The destination shapes the experience. A move within the EU or EEA brings the automatic deferral, with the lightest formalities. A move to a third country generally still allows the deferral, but it may have to be requested and backed by guarantees, and the follow-up is more demanding.

This does not make a third-country move disadvantageous, many of the most attractive destinations are outside the EU, but it does mean the exit-tax formalities require more anticipation. The guarantees, in particular, can take time to arrange and should be anticipated well before the move.

Factoring the destination into the exit-tax planning is therefore part of preparing the departure. The substance of the relief is similar; the procedure differs in formality and in the guarantees required, and that difference is worth anticipating well before the move rather than discovering it at departure.

Tax treaties

The tax treaty between France and your destination interacts with the exit tax, notably to prevent the same gain from being taxed twice if you eventually sell as a resident of the other country. Treaties allocate the right to tax capital gains and provide relief mechanisms.

The precise interaction depends on the treaty, which should be read for your specific destination. It is what ensures that the French exit tax and the other country’s taxation of the eventual sale do not overlap into double taxation.

As always in cross-border matters, the applicable treaty is the reference, not a general rule of thumb. Reading it for your specific destination is the way to understand how your eventual disposal will be taxed, and to avoid any double charge between France and your new country of residence on the same gain.

Common mistakes

1. Believing you must pay at departure. The tax is almost always deferred at departure, and usually cancelled in the end, so few people who leave France actually end up paying it in cash, despite the regime’s fearsome reputation.

2. Forgetting the reporting at departure and the annual follow-up, which secure the deferral.

3. Selling securities too soon and crystallising a tax that would otherwise have been cancelled.

4. Overlooking apport-cession gains, which are in scope regardless of the thresholds.

5. Assuming real estate or direct crypto is caught, they are not.

6. Underestimating third-country formalities, including guarantees.

Your checklist

If you are leaving France with securities:

1. Check the thresholds (€800,000 of securities or a 50% stake; any amount for apport-cession gains).
2. Identify what is in the base (securities) and what is excluded (real estate, direct crypto).
3. Secure the deferral (automatic for the EU/EEA; on request, with guarantees, for third countries).
4. Plan your holding period so the tax is cancelled rather than triggered.
5. File the departure return and the annual follow-up.
6. Analyse any apport-cession gain separately.
7. Read the treaty of your destination for the eventual sale.
