Proskauer adds new talent to tax practice. Published on 08/10/2026 The new partner will enhance its private funds tax capabilities. International law firm Proskauer Rose has welcomed tax partner Julio Castro to its London office, where he will advise asset managers and fund sponsors, including private equity, credit and secondaries managers, on a broad range of US tax matters. Prior to joining the firm, Castro worked at global accounting firm KPMG for over a decade, where he advised private investment fund sponsors on the tax aspects of the full lifecycle of funds. Castro has experience guiding clients on GP stake sales, structuring carried-interest arrangements, the tax aspects of cross-border M&A and designing related holding and financing structures. He has also advised Latin American clients on international tax matters in the US, including US fundraising, IPOs, expansions and restructurings. Proskauer's Chairman Tim Mungovan said: "Client demand for sophisticated, cross-border tax advice continues to grow. Julio brings deep experience advising clients on complex fund formations and strategic transactions, helping clients navigate the tax considerations that are critical to achieving their objectives. He will be a great addition to our team." Co-head of Proskauer's private funds group Nigel van Zyl added: "We have continued to invest strategically in our global Private Funds platform so we can work alongside our clients as their needs evolve. As fundraising strategies become more bespoke and GP-led transaction activity increases, demand for seamless U.S. tax advice in Europe has never been greater. Julio adds depth to an already market-leading team and further differentiates our ability to deliver integrated solutions to sponsors and investors around the world." Castro concluded: "Proskauer has an outstanding reputation for advising many of the world's leading private capital sponsors on their most complex and innovative matters. As clients continue to operate in an increasingly dynamic environment, I am eager to help them address their US tax and transactional needs, and to contribute to the continued growth of the practice globally."
