A global mobility policy is the cornerstone document that defines how an organisation manages employees who work across international borders. It sets out the scope of assignment types covered, eligibility criteria, compensation and benefits principles, tax and social-security treatment, immigration support, relocation assistance, and the administrative process from pre-assignment planning through to repatriation. A well-drafted policy creates consistency, manages employee expectations, and reduces legal and financial risk for the employer.
Modern mobility policies typically distinguish between short-term business travel, short-term assignments, long-term assignments, and permanent transfers, as each category carries different tax, immigration, and employment-law implications. The policy should address whether the company applies tax equalisation or tax protection, how allowances are structured, and which entity bears the cost of mobility.
Regular policy reviews are essential to keep pace with changes in tax treaties, immigration regulations, and social-security rules. The introduction of the 183-day rule scrutiny by tax authorities, the EU Posted Workers Directive revisions, and increased A1 certificate enforcement have all prompted policy updates across organisations operating in Europe. Policies should also reference the obligation to obtain A1 certificates, posting notifications, and work permits before any assignment commences.
