Mirror payroll: when is it essential, and how do you implement it?
The international growth of French companies increasingly leads employers to send employees to work abroad. In this context, one concept comes up frequently: Shadow Payroll. Still little known among many SMEs, this arrangement is nonetheless widely used by international groups to comply with the host country's tax and social obligations, without necessarily changing how the employee is paid.
What is Shadow Payroll?
Shadow Payroll, or 'ghost payroll', is a payroll set up in the host country purely for reporting purposes. Unlike a standard payroll, it doesn't result in an additional salary payment to the employee, who generally continues to be paid by their French employer or another group company. The locally produced payslip mainly serves to declare income to local authorities, calculate any social contributions due, determine applicable tax withholding, and comply with the host country's legal obligations.
Why set up a Shadow Payroll?
Some legislation requires employers to locally declare income earned by an employee working in their territory, even if that income is paid from abroad. Shadow Payroll helps comply with local obligations, limit the risk of sanctions, ensure compliance with social and tax declarations, and facilitate checks by local authorities.
When is Shadow Payroll used?
Expatriation (an employee is assigned long-term to another country while continuing to be paid from France), intra-group mobility (a French company seconds an employee to a foreign subsidiary), international executives, and long-term assignments requiring local reporting obligations even without local payroll.
Split Payroll vs Shadow Payroll — what's the difference?
These two concepts are often confused. Split Payroll splits remuneration between several countries or employers. Shadow Payroll, on the other hand, is a declarative payroll that doesn't necessarily change how the salary is paid. In some situations, both arrangements can be used simultaneously.
What are the employer's obligations?
Before setting up a Shadow Payroll, several elements must be analysed: the applicable social security regime, tax obligations, local reporting requirements, applicable international agreements, remuneration terms, and each group company's responsibilities.
Consequences for payroll and taxation
Even without a second salary payment, Shadow Payroll requires significant coordination: reconstructing taxable remuneration, integrating benefits in kind, valuing certain allowances, calculating local contributions, preparing mandatory declarations. International taxation is one of the main challenges: the employee's tax residence, tax treaties, withholding at source, reporting obligations, risks of double taxation.
Most common mistakes
Missing Shadow Payroll where required, poor reconstruction of remuneration, errors in benefits in kind, poor coordination between group companies, missing declarations, insufficient documentation.
Conclusion
Shadow Payroll has become an essential tool of international mobility. Although invisible to the employee, it plays a key role in the compliance of companies operating abroad. Its implementation requires close coordination between stakeholders, good knowledge of local regulations, and anticipation of social and tax consequences.
