Social Security

International mobility has a direct impact on employees’ social security. The question of where a person is covered by social security determines where contributions are paid and which social security benefits apply.

When employees are assigned to work abroad, this is not always clear-cut. European regulations and international agreements require that the responsible country be determined on a case-by-case basis. This affects both the employee and the employer and calls for a careful and well-founded approach.

Nassau advises organizations on social security matters related to international employment. We assist in determining the applicable legislation and ensure that it is properly implemented and administered in practice.

Our support includes, among other things:

• Application of European social security rules and conventions

• Assistance with A1 declarations and evidence

• Assessment of international social security statuses

• Support for secondments and temporary assignments

• coordination between payroll, tax, and global mobility

This approach provides organizations with clarity and helps prevent risks. We’re happy to work with you to quickly and practically assess your situation.
