• Execute corporate and holding-structure projects, including legal-entity rationalization, financing, withholding-tax and treaty optimization, and repatriation.
• Lead tax workstreams related to M&A and post-merger integration, from due diligence and structuring through integration into the Group’s operating and tax model.
• Drive tax planning initiatives, including ETR and cash-tax optimization, tax attributes, incentives, and scenario modeling.
• Manage tax audits and controversy matters, while supporting APA, MAP, rulings, valuation, and restructuring documentation where required.
• Explore opportunities related to investment incentives, subsidies, grants, and VAT optimization.
• Embed AI- and data-enabled ways of working within Group Tax and manage external advisors with a strong focus on value, quality, and knowledge transfer.
