Global Mobility

International staff assignments are daily practice for global companies. Depending on the purpose of the assignment they can reach from a few months, that an employee spends e. g. in the German subsidiary of a U.S. company supporting a controlling project, up to several years, when for example a CEO position in the Chinese branch is to be filled.

It also happens that the employee is working at the same time for his company at home as well as abroad. In this context complex tax, social security and labor law issues do arise – both for the company and for the individual employee and his family. Starting with the selection of the most suitable candidate for the position abroad, the design of remuneration components, up to the question whether the employee is accompanied by his family for long-term postings abroad; or if assistance is needed, among other things, for obtaining visas, work permits and for health and social security issues. Not to mention the tax office claiming the tax return at home and in the host country.

All these activities and issues cost a lot of your Company‘s and your employee‘s time and energy – which is lacking ultimately for your core business. Mazars takes care of you and your staff in a personal and pragmatical way so that your staff can concentrate on the essentials. This is important to us.
