About
We are a UK based tax firm providing UK and US personal tax advisory and compliance services.
We provide bespoke, clear and practical solutions to our clients as they navigate the ever-growing complex UK and US personal tax environment.
We do this by providing a high level of client service, working alongside our clients to add clarity to their UK/US tax position, building a long standing trusted relationship.
We offer a fixed fee service to our clients for both advisory and compliance matters, based on the complexity of the work required. We will quote for work upfront for full transparency, avoiding any unexpected bills.
WHY CHOOSE STERLING TAX?
We are UK and US qualified tax experts with over 30 years of combined tax experience. Having worked within the Big 4 and market leaders throughout our respective careers we understand the importance of client relationships, and how these are unique to each and every client and not off the shelf.
We're commited to a personalised, proactive service to our clients, understanding their specific circumstances and goals and a providing bespoke client relationship.
Long standing client relationships are the cornerstone of our business.
As founders, we have both worked together during our careers and have continually noted during that time how important the client is and how it should forever be at the forefront of any consideration. We apply our respective skill set to each client, ensuring that every client is aligned to the most appropriate advisor, although our skill sets are different and complement each other, where we overlap is providing a sterling tax service to our clients.

I am the co-founder of Sterling Tax, having started in tax in 2007 at Frank Hirth PLC working at various firms (including the Big Four) providing tax advice and compliance to high net worth individuals.
During my time I have supported with all manner of UK/US tax considerations with a diverse client base, that being said I specialise in dual residents, expats, Expatriation, inbounds into the UK or the US, sale of property, and review of investment structures for optimisation of tax efficiencies.
I hold relevant qualifications in both the UK and US (ATT and EA, respectively). My personal goal is be a fully trusted tax advisor to my clients offering the highest level of guidance and support, allowing for support in their life and financial goals.
Outside of work, I enjoy being a “nerd”, gaming (both retro and current) as well as spending quality time with my two young children and overly excitable pug. I have been told I enjoy a pint, occasionally.

I am the co-founder of Sterling Tax, with over a decade of experience in international tax advice.
Prior to establishing the firm, I have spent the majority of my career at Big Four accounting firms, where I developed deep expertise in cross-border taxation, compliance, and strategic planning for high-net-worth individuals and their families.
I specialise in the unique tax challenges faced by clients with UK-US ties, including expatriates, dual residents, and individuals with complex international holdings, such as carried interest and co-investment.
I am known for skills in managing intricate financial situations, often involving multi-jurisdictional compliance, tax-efficient structuring, and wealth preservation.
I hold relevant qualifications in both the UK and the US (ATT and EA, respectively). My personal goal is to provide the highest level of personalised service, helping clients successfully navigate the complexities of US-UK taxation and secure their financial future.
Outside of work I enjoy unwinding by catching a football match, exploring the local vibrant restaurant scene, and spending quality time with family and friends.
