Moving abroad does not make your French social security rights disappear overnight. But keeping them requires active steps, and the rules vary significantly depending on your status, destination, and length of stay. This article sets out what you genuinely keep, what you lose, and what you can rebuild.

Posted worker or expat: a fundamental distinction

Before anything else, your administrative status determines everything. The two situations work very differently.

The posted worker

A posted worker is an employee sent temporarily abroad by their French employer, while remaining attached to the French company. They continue to contribute to the French social security system and retain their rights (health, retirement, unemployment) as if they were in France. The employer pays employer contributions in France.

The maximum posting duration varies depending on the applicable agreement: in principle 24 months within the EU (renewable once under conditions), and according to bilateral conventions for non-EU countries. The A1 form (certificate of applicable legislation) is mandatory: it proves that you remain under French legislation and prevents dual affiliation.

Without a valid A1, the host country can demand local contributions. This is one of the most expensive traps.

The expatriate

An expatriate employee (or a person who leaves on a personal basis) exits the French social security system. Their employment contract is often directly with a foreign company, or they work independently in the host country. They then contribute to the local scheme and build up rights there.

In this case, maintaining French rights requires voluntary steps: joining the Caisse des Français de l’Étranger (CFE) for health insurance and retirement, or contributing to supplementary schemes.

Health insurance: what actually happens

The gradual loss of CPAM entitlements

Your social security rights do not stop on the day you leave, but they fade progressively. The rights maintenance period is set at 6 months after the end of your activity in France (or up to 12 months depending on your contribution history). After that period, you exit the scheme.

In practice, if you leave to work abroad for a local employer, you will need, from the moment you settle, to either join the local scheme or take out voluntary coverage. Waiting until the maintenance period ends without acting means ending up uninsured.

Details on maintained rights and their duration are available on ameli.fr and service-public.fr.

The CFE for health insurance

The CFE allows expatriates to maintain health and maternity coverage modelled on the French general scheme. Contributions are calculated by income bracket. It is a voluntary baseline, not automatic.

Important note: CFE reimbursements are based on French social security rates, which are often well below actual costs abroad. The CFE is designed to work alongside an international supplementary policy. See our dedicated article on expat health insurance for a full breakdown of the options (CFE, private insurance, local system).

Within the European Union

If you work in an EU/EEA country or Switzerland, you are affiliated to the local scheme. EU Regulation 883/2004 coordinates social security systems between member states, allowing in particular the aggregation of insurance periods to access rights. The European Health Insurance Card (EHIC) remains useful for care during temporary stays in other EU countries.

Retirement: vested rights, gaps, solutions

What you keep no matter what

Quarters validated in France before your departure do not disappear. They remain permanently recorded in your retirement account, accessible at info-retraite.fr. You can use them when you draw your French pension, regardless of your country of residence at that point.

The problem lies in the quarters not contributed during expatriation. Every year spent abroad without French contributions is a gap in your career, which may push back your full-rate retirement age or reduce your French pension amount.

Voluntary contributions via CFE retirement

The CFE offers a voluntary retirement contribution. It lets you continue accumulating French pension rights during your expatriation, even if you are no longer employed in France. Contributions are calculated on a declared basis, with a minimum and maximum.

This is particularly relevant if you started your career in France, are leaving between the ages of 30 and 50, and want to draw a full-rate French pension rather than relying solely on a foreign one.

Bilateral retirement conventions

France has signed bilateral social security conventions with around forty non-EU countries, including the United States, Canada, Japan, Australia, Morocco, Tunisia, Brazil, Argentina, South Korea, and others. These conventions generally allow period aggregation: years contributed in both countries are combined to determine whether you meet the threshold to open rights, even if the pension is paid on a pro-rata basis.

The CLEISS (Centre des Liaisons Européennes et Internationales de Sécurité Sociale) is the reference body for finding signatory countries and the terms of each convention. Check their up-to-date list before making any retirement decisions.

Unemployment: a frequently underestimated issue

ARE entitlements when you leave

If you have ARE (Allocation de Retour à l’Emploi) rights at the time of your departure, you do not necessarily lose them. You can suspend your job-seeker registration and preserve your French entitlements to reactivate on return, provided you re-register with France Travail within the prescribed deadlines.

However, if you leave without any open ARE rights, you cannot contribute to French unemployment insurance from abroad (except as a posted worker).

Within the EU: coordination under 883/2004

EU Regulation 883/2004 includes coordination mechanisms for unemployment between member states. If you have worked in several EU/EEA/Swiss countries, employment periods in each country can be aggregated to open rights in your last country of activity. Concretely, if you return to France after working in Ireland or Spain, your Irish or Spanish periods may be counted towards your France Travail entitlements, subject to conditions.

Outside the EU: generally lost

Outside the EU, and except for specific bilateral conventions, there is no unemployment coordination mechanism. If you work in Morocco, Canada, or the UAE, your local years of activity do not feed into your French unemployment rights. On return, you start from scratch for rebuilding ARE entitlements.

EU coordination in detail

EU Regulation 883/2004

This regulation is the cornerstone of social coordination in the EU/EEA and Switzerland. It establishes several fundamental principles: single applicable legislation (you can only be subject to one scheme at a time), equal treatment, aggregation of insurance or employment periods, and portability of certain benefits.

In practice, this means quarters validated in one EU country can be used to open rights in another member state, even if each country pays its share pro rata of the periods completed on its territory.

The A1 form

The A1 form is the official certificate confirming which social legislation applies to a worker. It is issued by the competent body in the country whose legislation you continue to fall under (in France: URSSAF or CPAM depending on the case).

Without an A1, the host country can legitimately subject you to its own social legislation, creating dual affiliation and dual contributions. Obtaining the A1 before departure (or at the earliest opportunity during a posting) is a practical obligation, not merely an administrative one.

The European Health Insurance Card (EHIC)

The EHIC is free and valid for 2 years. It provides access to necessary care during temporary stays in another EU/EEA/Swiss country, under the conditions of the local scheme. It does not replace coverage in your country of residence.

Bilateral conventions outside the EU

France has concluded social security conventions with approximately 40 countries, including the United States, Canada, Japan, Australia, Morocco, Tunisia, Senegal, Brazil, Argentina, South Korea, and others. These conventions generally cover health, retirement, and sometimes workplace accidents, under terms specific to each agreement.

They allow:

  • Avoiding double contributions (the single-legislation principle applies outside the EU via convention)
  • Aggregating periods to open retirement rights
  • Maintaining certain benefits during stays in the other signatory country

The full list of signatory countries and the content of each convention are available at cleiss.fr. If your destination country is not a signatory, you are in principle subject to its local legislation with no coordination with the French scheme.

Family benefits and allowances: what lapses

Family allowances

French family allowances (CAF) are paid to families residing in France. Once you transfer your residence abroad, you are in principle no longer entitled to CAF benefits (family allowances, housing benefit, birth bonus, PAJE childcare allowance, etc.).

Some exceptions exist for expats maintaining CFE affiliation or posted workers, where certain family benefits may be maintained under conditions. The rules are complex and depend on your exact situation. Check with your CAF office before you leave.

Residence-linked benefits

Several French social benefits (RSA, ASS, AAH) are conditional on regular residence in France. Moving abroad automatically triggers the loss of these rights, with a few exceptions for maintained temporary stays.

Summary table: EU vs non-EU

Risk EU/EEA/Switzerland Non-EU (with convention) Non-EU (no convention)
Health Local scheme + EHIC coordination for temporary stays Local scheme; some conventions provide partial portability Local scheme only; French rights lost unless voluntary CFE
Retirement EU period aggregation; pro-rata pension from each country Aggregation per convention; pension paid by each country No aggregation; French rights frozen, local rights separate
Unemployment Aggregation possible; coordination for rights opening No unemployment coordination in general French rights lost if not maintained; no coordination
Family Priority rules between states; no double payment Depends on convention (rare for family allowances) Loss of French CAF benefits

Pitfalls to avoid

Pitfall 1: assuming you keep everything automatically

This is the most common mistake. Vested rights remain vested, but active coverage stops if you do nothing. Health, family, unemployment: all these entitlements require either active maintenance (CFE, convention) or local affiliation. Doing nothing means ending up uncovered.

Pitfall 2: forgetting the A1 form

For posted workers, the A1 is mandatory and must be obtained before departure. An employer who sends an employee abroad without an A1 is exposed to tax adjustments in the host country. A self-employed person working across several EU countries without an A1 may face double contributions. This is not a formality: it is protection.

Pitfall 3: retirement career gaps

Every year of expatriation without contributions is a missing quarter. Over 10 years abroad without voluntary CFE contributions, that is 40 missing quarters — potentially 10 years’ delay to full-rate retirement, or a significant reduction. This calculation is easy to ignore at 35 and difficult to recover at 55.

Pitfall 4: countries without conventions

If you move to a country with no bilateral convention with France, there is no automatic coordination. You contribute to the local scheme and lose French rights not voluntarily maintained. Check the list of conventions on cleiss.fr before making your decision.

Frequently asked questions

Does my French retirement account disappear if I move abroad?

No. Rights already accrued (quarters, points) remain permanently recorded. You can view them at info-retraite.fr and use them when you draw your pension, regardless of where you live. What stops is the accumulation of new French rights if you are no longer contributing.

What happens if I return to France after a long spell abroad?

You re-enter the French general scheme on your return (through employed or self-employed activity). For unemployment, you build entitlements from scratch unless you had preserved ARE rights. For retirement, the years without contributions create a career gap, but rights accrued before departure remain. The CFE retirement option may have filled that gap if you subscribed.

Is the CFE compulsory for expats?

No. The CFE is a voluntary scheme. Nothing obliges you to join. But without it, you lose French health coverage and stop accumulating French pension rights. For those who want to maintain a strong link to the French system, it is often the most appropriate solution.

Can my foreign employer contribute to my French retirement?

Not directly. A foreign employer contributes to its own country’s scheme. To contribute to French retirement, you as an individual must join the CFE retirement scheme voluntarily. Some expatriate contracts include partial employer coverage of this contribution, but that is a contractual negotiation, not a legal obligation.

Social protection abroad is not something to sort out after you have settled. Every month without active coverage is a real risk: illness, an accident, or hospitalisation without insurance can cost tens of thousands of euros. Take the time to review your situation before you leave.
