• Increased tax compliance in income tax, VAT, and transfer pricing by creating compliance guidelines based on current tax regulations and delivering training to involved teams.
• Promoted cross-department collaboration by establishing regular tax meetings and project groups.
• Prepared detailed pro/con analyses of the tax impact of business decisions, incorporating different stakeholder perspectives to enable informed decision-making.

• Conducted interviews and data collection, leading to a significant increase in transparency for tax management.
• Creating the risk control matrix also enabled quick identification of risks and corresponding measures to minimize them.

• This ensured compliance with internal and external quality requirements while also meeting the demands of efficient project management.
