Iain Younger

Spear’s Review

Iain Younger advises HNW individuals across a diverse range of generations, industries, backgrounds, and wealth levels. He told Spear's: ‘What binds them together is the complexity of the US and/or UK “foreign tax” exposure. It’s in those complex situations that we add value.’

He joined Frank Hirth’s audit team in 2000 and has built the trust and estates service within its private client offering during his 20-year career at the firm. He joined the board of directors in 2016, and personally covers numerous areas of US and UK taxation for individuals and families, offering specialist advice relating to FATCA reporting. A 19-year mentorship under late chairman Paul Hocking provided him with invaluable experience of the private client space.

Adviser Profile

Although Iain Younger’s private client background within US & UK international tax matters covers a wide range of issues, his area of specialist expertise revolves around Trust, Estate & Succession planning matters. 

Iain Younger provides his clients with ‘proactive, practical tax planning opportunities founded on a clear understanding of their goals for themselves and their families’, identifying potential pitfalls while creating efficient solutions. 

The US international market has continued to become increasingly complex, which is heightened when a client also has UK exposure. Navigating two of the most complex tax systems can limit the planning available, but certainly does not mean nothing can be done. It is essential to understand the parameters for each client and work with them to build and influence a strategy that meets their goals. Where the US and another jurisdiction is involved, avoidance of double taxation is the minimum that any planning is looking to achieve. We then build the planning from there, again alongside empathy towards the client’s wider objectives. 

Post-pandemic, it appears that tax in many cases is not the main driver behind considerations for wealth structuring but must always be recognised as one of the contributing factors that must be considered and understood. As a part of EY, more so than ever, our clients span such a wide breadth of industries, personalities and motivations, which can lead to interesting challenges being presented to us.  It is those challenges that we relish, and finding the right answer for the client, whatever that may be, is the goal that we strive for. 

Younger joined Frank Hirth’s audit team in 2000, and has built the trust and estates service within its private client offering during his 20-year plus career at the firm. He gained invaluable experience following his appointment to the board of directors in 2016, which allowed him to contribute to not only his practice area but to the firm. 

The continued success of Frank Hirth is built upon the strong foundations of teamwork, experience and technical excellence. This is now embodied within EY’s US/UK Cross Border team, and we are now able to set our bar and ambitions even higher. The team remains at the core of what we do, and the continued development his colleagues provide huge satisfaction and pride. 

Younger is a qualified Chartered Tax Adviser, a US Enrolled Agent and a member of STEP, and a trustee of NPT-Transatlantic, dealing with effective charitable giving for US/UK connected individuals and families. He is a proud trustee of the National Philanthropic Transatlantic, exposing him to the wider philanthropic landscape, which proves useful when advising clients with charitable interests.
