4th VAT Summit

The fourth VAT Summit will take place at Grant Thornton in Düsseldorf on 25 and 26 February 2026. We are looking forward to much dialogue with you on national and international VAT. 

Here’s how you can stay up-to-date

The subject of VAT is complex. Every year there are changes on the international market. Digital tools in this area are constantly becoming more wide-ranging, regulations are changing, and the field is developing at a fast pace. That’s why imparting knowledge and face-to-face dialogue are still at the forefront of our VAT Summit. We would like to give tax practitioners the chance to dialogue and find out about the current international trends in VAT. Our experts and representatives from the Grant Thornton network will explain current topics in presentations and workshops. There will also be the chance to network. 

Please note that the event will take place in English.
