During the workshop, the speakers cover:
Challenges and opportunities of AI
What an AI strategy entails
Why a thoughtful AI strategy is crucial in the current era

This workshop will discuss the legal aspects of using AI within tax services. As AI is increasingly used to support day-to-day operations, it is crucial that tax professionals are aware of the rules surrounding privacy, data protection and security. What is allowed and what is not? Where are the risks? And how do you ensure that your organization is compliant?
During this interactive session, you will get answers to frequently asked questions, such as:
How do I stay within the frameworks of the AVG and AI-Act when using AI?
What documentation and agreements are needed to be compliant?
Do I need to get permission from my clients when I want to use AI?
How do I fulfill my transparency obligation?
What does ISO certification mean in the context of security and AI?
Can I use American providers?
The workshop is specially designed for tax professionals, with plenty of room for questions, practical examples and concrete tools that you can immediately apply within your own organization.

During this interactive workshop, we will discuss how various classical and contemporary philosophers would look at Artificial Intelligence and society and what this means for our own position and taxation.
