Retirement abroad confronts every future retiree with a fiscal and administrative puzzle whose pieces change depending on the country of residence, the type of pension received, and the applicable bilateral agreements. Rather than providing a general overview, this article measures the concrete differences between staying in France and leaving, based on the rules applicable since the Social Security Financing Law for 2026.
Social contributions on French pensions: resident vs. non-resident
The tax status directly determines what is deducted from a French retirement pension. Since the LFSS 2026, the distinction is clear.
| Deduction | Tax resident in France | Non-tax resident |
|---|---|---|
| CSG | Applicable (variable rate depending on income) | Exempt |
| CRDS | Applicable | Exempt |
| CASA | Applicable | Exempt |
| Health insurance contribution (CotAM) | Not applicable | May apply depending on the situation |
The exemption from CSG, CRDS, and CASA for non-residents no longer depends on an income threshold. It is based solely on the non-tax resident status. This change simplifies the calculation, but it does not eliminate all burdens.
The CotAM remains a often overlooked item. An expatriate retiree who retains rights to French health insurance may have this contribution deducted from their basic pensions (CNAV, MSA, public service) and supplementary pensions (Agirc-Arrco, Ircantec). Before preparing for international retirement abroad, it is therefore necessary to model the tax/health coverage couple, not just the income tax rate.
Tax treaty and type of pension: the gap that changes everything
The taxation of a French pension received abroad depends on its origin. Bilateral tax treaties generally distinguish between two categories: public pensions and private pensions. This distinction creates considerable differences from one country to another.
Public pensions and private pensions
A public service pension is most often taxable in France, regardless of the retiree’s country of residence. In contrast, a private pension (general scheme, Agirc-Arrco) is generally taxable in the country of residence, according to the terms of the applicable treaty.
A former civil servant who moves to Portugal does not receive the same tax treatment as a former executive from the private sector. The type of pension determines the country of taxation, not just the retiree’s address.
Countries without a tax treaty
In the absence of a bilateral treaty, the risk of double taxation becomes real. The pension may be taxed in France based on its source and in the country of residence based on the tax domicile. Some retirees choose destinations like Albania or Thailand for the cost of living, without checking beforehand the existence or content of a treaty. The absence of a tax treaty can negate any advantage related to the cost of living.
Certificate of life and pension exportability: what has changed in 2026
A persistent idea is that a French retiree must return to the territory every six months to retain their rights. Several pension funds have confirmed that there is no such obligation. The French retirement pension is a transferable property right, without any condition of physical presence in France.
The other notable change concerns the certificate of life. Since March 2026, this annual formality has been removed for retirees residing in certain countries that have a civil status data exchange system with France. For other destinations, sending the certificate remains mandatory and conditions the continuation of pension payments.
- Check if the country of residence is on the list of countries exempt from the certificate of life, updated by the pension funds.
- Keep complete documentation of the contribution periods in each country crossed during the career.
- Anticipate processing times: a request for the liquidation of rights acquired in several countries can take several months.
Voluntary contribution to the CFE: a calculation to make before departure
Expatriates who are not covered by any local mandatory scheme have the option to voluntarily contribute to the Caisse des Français de l’Étranger (CFE) for retirement and health insurance. This option ensures the continuity of French rights, but its cost varies significantly based on declared income and the chosen bracket.
The common reflex is to contribute at the minimum to limit expenses. Contributing at the minimum to the CFE mechanically reduces the validated quarters and the future amount of the pension. Conversely, contributing on a high basis during a long expatriation can represent a significant investment whose return depends on life expectancy and the tax regime at the time of liquidation.
The decision hinges on three variables:
- The expected duration of expatriation and the number of quarters already acquired in France.
- The existence of a local mandatory scheme in the host country, and the possibility of combining these rights with French rights through a bilateral social security agreement.
- The cost differential between the CFE contribution and an investment in individual retirement savings (Luxembourg life insurance, transferable PER, local capitalization).
Local schemes and totalization of quarters: the trap of fragmented careers
An expatriate who has worked in three or four countries accumulates rights in each scheme, but these rights do not automatically add up. Within the European Union and the European Economic Area, coordination regulations allow for the totalization of insurance periods to open the right to a pension, without merging the amounts.
Each country pays its share, calculated pro-rata based on the periods completed on its territory. Totalization opens the right, but each country calculates its pension separately. A retiree may therefore receive three or four modest pensions rather than a single full pension.
Outside the EU/EEA, everything depends on the existence of a bilateral social security agreement. Without a treaty, the quarters contributed abroad may never be recognized by the CNAV. Fragmented careers between treaty and non-treaty countries produce the most unfavorable discrepancies at the time of liquidation.
The data that conditions all this planning remains the inter-scheme career statement. Requesting it several years before departure, then updating it with each change of country, allows for a precise measurement of the gap between acquired rights and the targeted income level at retirement.
