The Institute for Austrian and International Tax Law, WU is organizing the conference "Turnover Taxes (including VAT/GST, Digital Service Taxes) in the Light of Treaty Law" in cooperation with the Doctoral Program for International Business Taxation.

Turnover-based taxes such as VAT/GST and digital service taxes have the potential to give rise to cross-border disputes such as double taxation. The conference aims to facilitate a comparative analysis of how such taxes are addressed under existing treaty frameworks, including double tax conventions based on the OECD/UN Model, bilateral or multilateral agreements that are specifically designed to regulate VAT/GST and other turnover-based taxes, as well as non-tax agreements, covering both substantive issues and procedural aspects such as exchange of information and non-discrimination.

The conference will be preceded by a doctoral seminar on the conference topic and a welcome dinner on July 2, 2026. The working sessions will be held all day on July 3 and 4, 2026 and the conference will end on Saturday, July 4, 2026 after dinner.

Doctorate Workshop

As part of our conference we are looking for PhD candidates researching on the topic of artificial intelligence and taxation to present their current work. This provides an excellent opportunity to receive feedback on your research as our research and teaching associates will comment on and give feedback on the presentations. This will be followed by a discussion with the professors, researchers and other experts who are attending the adjoining conference.
