Employees and Executives posted abroad
Taxation of posted employees and expatriates involves complex challenges that require specialist advice. At addwill, we offer end-to-end advisory services on the application of Article 7p exemption (LIRPF) and support with the tax management of internationally mobile staff.
We use powerful tools to implement and monitor the 7p exemption for employees temporarily assigned abroad as part of their work responsibilities.
Our team is led by Jordi Vilardell, partner at addwill’s Tax Department in Brussels, with recognized experience advising employees, companies, and international groups in this field.
