Expatriate, detached employee and impatriate are often used interchangeably. For employers, they create very different consequences: employment contract, social security, A1 certificate, withholding tax, tax residence, shadow payroll and total employer cost.
Executive Summary#
Detachment usually covers a temporary assignment with possible continued French social security coverage under conditions. Expatriation points to a longer move outside France, with country-by-country social and tax analysis. Impatriation concerns arrival in France and may, under conditions, benefit from the French impatriate tax regime.
Decision Matrix#
| Leadership situation | Working option | Control point |
|---|---|---|
| Temporary assignment in EU/EEA/Switzerland | Detachment | A1, duration, employer link and work country |
| Long-term move outside France | Expatriation | Tax residence, local contract and social protection |
| Recruitment from abroad into France | Impatriation | Article 155 B, allowance and reference remuneration |
| Employee works in several countries | Multi-state activity analysis | Social security rules and tax treaties |
Control Points to Document#
- Residence country, work country, duration and presence pattern.
- Legal employer, subordination link and intra-group recharge.
- Social security: A1, bilateral agreement or local affiliation.
- Tax: residence, treaty, withholding and annual filing.
- Payroll: French payslip, local payroll, benefits and possible tax equalisation.
Operational Example#
Illustration: a French employee sent to Germany for 18 months by a French employer may fall under detachment if EU conditions are met. The same person hired directly by a German subsidiary on an indefinite basis requires expatriation or local contract analysis.
Our Chartered Accountant's View#
We start from real payroll facts: who pays, where work is performed, who bears cost, which social regime applies and which tax filing follows. International HR policies fail when contract, payroll and tax tell different stories.
The Underestimated Risk#
The underestimated risk is improvised status. A contract calling someone detached while payroll is local, no A1 exists and presence is long-term can expose the employer to local contributions, penalties and unmanaged double taxation.
What Leadership Must Decide#
- Qualify mobility before departure or arrival.
- Request certificates or advice before first payroll.
- Choose policy for housing, school, tax and social protection support.
- Inform the employee about personal filing obligations.
- Update intra-group agreements and recharges.
2026 Watchpoints#
- The French impatriate page was updated on 8 April 2026.
- EU detachment requires employer formalities and duration monitoring.
- Tax residence cannot be chosen by contract clause.
- Cross-border telework may change social security analysis.

Frequently asked questions
What is the difference between expatriate and detached employee?+
A detached employee usually remains linked to the original employer for a temporary assignment with possible continued home social security. An expatriate is closer to a long-term move or local contract.
Is the French impatriate regime automatic?+
No. It requires specific conditions, including prior non-French tax residence and relocation to France for the role.
Who determines tax residence?+
Facts and tax treaties, not the employment contract. Home, days, main activity and economic interests must be reviewed.
Does an A1 certificate settle income tax?+
No. A1 concerns social security. Income tax requires a separate analysis of residence, work location and treaty rules.
When should mobility be reviewed?+
At offer or assignment letter stage. Later regularisation may be possible but costs more and creates uncertainty.
