Liège and its region are one of the most dynamic investment pools of the country. It’s only natural that thg has installed one of its offices there. This was done in 2010. thg Liège has grown rapidly since then, particularly since the takeover of the Phoenyx Tax office in 2011. Today we have a team of 15 employees.


Experience and competence at your service

Our client base is composed mainly of companies, self-employed people and associations. Our employees’ in-depth knowledge of company management is the best guarantee of a quality service that listens to your needs. We can guide you in many domains beyond accounting and tax services, at every stage in the development of your project:


  • Management and/or assistance in the management of your company (management control, budgeting, financial reporting, etc.)
  • Legal missions reserved for certified accountants (mergers, division, dissolutions, transformation of companies)
  • Writing of agreements (leases, spinoff companies, etc.)
  • Advice and submission of grant files to the Walloon region
  • Organisational, accounting and financial audits
  • Company evaluation and valuation


We are particularly attentive to the follow-up of your activities and we eagerly adapt to the technological changes in the field. Digitalisation? Not even scared! Several electronic changes have been implemented; our clients benefit from extended facilities in the management of their activities, while preserving (or even improving) the existing level of quality and security.


A wide network of specialists

All the employees of thg Liège have access to a wide network of active specialists within thg. We are able to respond to all your questions, whether they are about the creation or the acquisition of a company, questions related to commercial law, consolidation, estate planning, EU regulations or requests for aid at a national or European level.


Furthermore, our staff are in regular contact with external partners: banks, lawyers, notaries, ICT specialists or experts in interaction with authorities. All of them at your service.


Quality, prudence & foresight

Each member of our team fully adheres to the values and the philosophy of thg. Quality and reliability as well as prudence and foresight are all part of our DNA. This allows our clients to focus on their core business and in all circumstances, to stay ahead of the events. The quality of our work contributes to the security and prosperity of your activity.
