International Social Security Services
Navigate cross-border social security obligations with confidence.
International assignments and cross-border working arrangements can create complex contribution, registration and coverage requirements for companies and employees. EMS provides coordinated guidance to help determine the applicable social security position and manage the relevant obligations throughout the mobility lifecycle.
Discuss your social security requirementsOne working arrangement can create obligations across several systems
The country where an employee lives, the place where work is performed, the employing entity and the expected duration of an assignment may all affect social security obligations. Bilateral or multilateral agreements can change the outcome, but their application depends on the facts and the jurisdictions involved. Early review helps companies plan contributions, documentation and payroll treatment with greater certainty.
What the service can include
Support is adapted to the countries involved, the working arrangement and applicable agreements. It may include:
Social security position assessment
Review the employee, employer, work locations and assignment terms to identify the potentially applicable system.
Agreement and eligibility review
Consider relevant bilateral or multilateral coordination rules and the conditions attached to them.
Certificates of coverage
Support eligible applications and related documentation where a certificate or equivalent evidence is available.
Registrations and deregistrations
Coordinate applicable employer or employee social security formalities in the relevant jurisdiction.
Contribution guidance
Explain applicable contribution considerations and coordinate required information with payroll or local specialists.
Multi-country working patterns
Assess arrangements involving work in more than one jurisdiction, subject to the rules that apply.
Ongoing monitoring
Review relevant changes in location, duration, employer or assignment structure that may affect the position.
