Astrid Pieron has more than 30 years of tax experience, which includes 25-plus years of focus on international taxation. Her practice covers the fiscal aspects of financial functions within multinational groups, tax optimization of mergers and acquisitions, structuring of financial products and investment funds, and general assistance to private equity deals. Astrid has had a primary geographic emphasis on Brussels and Luxembourg throughout her career, and together with Mayer Brown’s Paris office (which won the 2006 Private Equity Award) she is advising on most of the significant private equity transactions that directly or indirectly are connected to the Benelux countries.
In addition to her transactional work, Astrid has substantial background in tax controversy matters, including assistance with tax litigation and negotiation of rulings with the tax authorities in Belgium and Luxembourg. Her experience in transfer pricing controversy includes examination, appeals and advance pricing agreements. She also counsels on the transactional aspects of transfer pricing, such as structuring European transfer pricing policy for US manufacturing groups operating in Europe. Astrid’s related work involves advising on the conversion to commissionaire structures as well as on the fiscal optimization of financial vehicles within multinational enterprises (such as captive insurance companies, treasury centers, and investment funds).
Before joining and subsequently becoming a partner in Mayer Brown’s Brussels office in 2007, Astrid practiced in Brussels and Luxembourg with two of the world’s leading tax and accounting firms: Deloitte (2002 to 2006) and Arthur Andersen (1981 to 2002). Reflecting her multinational practice, she is fluent in French, Dutch, and English.
