McDermott Will & Schulte announced that David Jamieson has joined the Firm as a partner in its Tax Practice Group in London. David joins from Baker McKenzie and brings deep experience in complex VAT and indirect tax disputes, adding further strength to the Firm’s growing tax disputes capabilities in London and across EMEA.

David is a highly experienced tax disputes lawyer whose practice focuses on complex VAT and indirect tax controversy matters. He advises multinational corporations, financial institutions and global businesses on high-value disputes, investigations, audits and litigation involving HMRC and other tax authorities. His experience spans the financial services, pharmaceutical, technology and e-commerce sectors.

“We have been looking to grow our tax disputes capabilities in London, and David brings exactly the kind of experience we want to add,” said Tim Shuman, global head of McDermott’s Tax Practice Group. “His deep expertise in VAT will be a real asset to our clients and complements the strength of our tax controversy practice in the US and internationally.”

David’s arrival is the latest step in McDermott’s continued investment in its London office and growing UK tax bench following the arrivals of partner and UK head of tax Alex Jupp and counsel Elizabeth Spencer last year.

“We have been very deliberate about building our London office with leading practitioners who share our ambition and entrepreneurial mindset,” said Aymen Mahmoud, managing partner of the Firm’s London office. “That’s what David brings. He is a highly regarded tax disputes lawyer with deep VAT expertise and a real appetite to grow. He is a natural addition within both our London and global teams and fits nicely into what is one of the pre-eminent tax teams in the world.”

Alex Jupp added “”High-end tax disputes work is a growing area of demand, and David is exactly the calibre of lawyer we want on our team. He strengthens our VAT offering, adds real depth to our disputes bench, and is another example of the quality of talent we’re attracting to London.”

A Solicitor Advocate, David regularly represents clients in tribunal proceedings and appeals. His practice encompasses strategic advice, investigations and litigation involving complex VAT and indirect tax issues, as well as advising on the indirect tax aspects of business operations, supply chains and international transactions.

“What attracted me to McDermott was the ambition of the Firm and the opportunity to be part of what Alex and the wider team are building in London,” said David Jamieson. “There is a real appetite for growth, alongside a collaborative approach that gives people the freedom to develop their practices. I’m looking forward to bringing my VAT and disputes experience to the team and working with colleagues in London and internationally.”
