At the heart of our activities

Tax advice holds no secrets for us. It’s been part of our DNA since the foundation of thg. Even if today we’re able to offer you a large range of services, tax advice remains the starting point of all our activities. In the current context marked by reduced scope for action, quality tax advice is essential.


There are plenty of challenges

Every day you’re confronted with an increasingly digital environment, you need to take into account the increased integration of tax regulations at the European Union level, you see the progressive reduction of your scope for action. Faced with these multiple challenges, classic tax advice is no longer sufficient. The level of competence must be increased, new ideas must be developed, bridges between the disciplines and the people must be established. At thg, we have understood this very well. Our fiduciary has become a consulting office that meets all your needs: from classic tax optimisation to the management of your intangible assets (brands, patents, etc.), to social secretariat services. Pick whatever interests you from this global offer and test our added value.


Think global, act local.

Companies that are active in the same region often share similar problems. This is why we decided to establish a wide and powerful local network. In addition, we have cross-border experience based on more than 35 years of practice. Our employees don’t just speak your language, they know the problems and challenges that your company faces on a daily basis.
