Global Employer Services

As a result of the ongoing globalisation, internationally operating companies are increasingly seconding employees abroad. In connection with the management of globally active employees, a large number of questions arise in various areas, such as taxation, social security and global remuneration.

Our Global Employer Services (GES) Team supports you in planning and successfully implementing your international secondment programme. So as to respond optimally to your needs and requirements and to offer tailor-made tax services, our team of experts works together with the heads of global mobility programmes as well as with the individual seconded or cross-border employees.

With our access to an international and interdisciplinary network of more than 48,000 people in about 120 countries, we are ideally positioned to assist you in organising and coordinating your mobility programme and, in particular, to ensure that all global tax obligations are met as cost-effectively as possible.

We offer a comprehensive range of mobility services that cover the needs of your company on two levels:

  • Satisfied employees
    We support the seconded employees during their entire international assignment - from the planning of the secondment to the successful reintegration of the employees into your company - in various areas, for example with calculations of the expected and actual tax burden according to the terms of secondment, with the taxation of the income in Germany and abroad, with the preparation of tax returns and much more.
  • Managment of secondment programme
    Our Global Employer Services plan and support your international secondment programme from its inception through to any changes and adjustments that may be required to keep the programme competitive, to take changes in global tax issues and other aspects into account, and to keep the programme aligned with your company’s development and requirements.
