Operating in over 150 countries, VAT monitoring is a pivotal measure to prevent fines and legal issues. To improve the existing monitoring workflow, this thesis investigates three questions: What are the potential VAT risks that should be addressed in the workflow? Have all the relevant stakeholders been identified, and have their responsibilities in the process been adequately defined? Is the workflow designed in a manner that offers clear and comprehensive guidance, ensuring that the sequence of steps is logical and complete?

To answer these three questions, the findings of a literature review and four semi-structured interviews with internal VAT experts are used. Data was collected in the fields of VAT risks and risk management approaches, BPMN requirements, and included a systematic analysis of stakeholders and their responsibilities, and process optimization measures.

These insights built the basis for the design of the improved workflow including a documentation of process-relevant VAT risks, process stakeholders and their responsibilities, and recommendations for the improvement of non-value adding steps. This improved workflow has the potential to support effective monitoring and handling of errors in the VAT management of this company. To achieve this ambition, several steps are recommended, such as the discussion of the new workflow with process participants, a correction of the modelling language, clarification of communication channels between the shared service centre and the internal local tax department, a discussion of the distinction between roles and risks of the global and local tax teams, and continuous training and process review.
