The 10 checkpoints for securing the payroll of an employee on international assignment.
Sending an employee abroad isn't just about organising their departure. From day one of the assignment, the company must ensure compliant management of payroll, social contributions, tax obligations and administrative formalities. A single mistake can quickly have serious consequences: double contributions, social or tax reassessment, back-pay, penalties, or disputes with the employee.
- Determine the right status. Is the employee seconded, expatriate, locally hired, or on intra-group mobility? This choice determines all of the company's social and tax obligations.
- Check international agreements. Applicable European regulations, bilateral social security agreements, international tax treaties, local reporting obligations.
- Organise social protection. Applicable social security scheme, health cover, retirement, provident schemes — the goal is to ensure continuous protection throughout the assignment.
- Structure remuneration. The expatriation package must be clearly defined: base salary, expatriation allowances, housing allowances, school fees, company cars, travel, benefits in kind.
- Choose the payroll setup. French payroll, local payroll, Split Payroll or Shadow Payroll — the choice depends on the country, length of assignment, group organisation and local obligations.
- Anticipate tax obligations. Tax residence, withholding at source, tax treaties, reporting obligations, risks of double taxation.
- Check payslips. When several countries are involved in remuneration, regular checks of salaries, contributions, benefits in kind, tax withholding and currency conversions become essential.
- Maintain oversight throughout the assignment. Extension, change of role, change in remuneration, relocation — each change can affect payroll.
- Prepare the return to France. Reintegration into French schemes, contribution corrections, payroll organisation, administrative formalities, updating of social files.
- Get expert support. International mobility draws on labour law, social security, taxation, payroll, HR and international agreements — it's rarely possible to master all these areas alone.
Most common mistakes
A wrong choice between secondment and expatriation, contributions paid in the wrong country, tax residence errors, poor management of Split Payroll, missing Shadow Payroll where required, incomplete documentation, lack of follow-up during the assignment.
Conclusion
Securing the payroll of an expatriate employee isn't just about producing a payslip. It's a comprehensive approach combining payroll, social protection, taxation, administrative obligations and HR management.
