DARLENE HART

DARLENE HART - FOUNDER - CEO

I founded USTAXFS in 1986 to provide US individuals living abroad with the specialized tax and investment services they needed. Since then, the firm has experienced significant growth, establishing offices in London, Zurich, and Geneva. Today, USTAXFS stands as the largest boutique tax accounting firm in the UK and Europe, specializing in US tax services for clients across more than 30 countries. I manage the firm’s Swiss offices and bring over 40 years of experience in tax, accounting, finance, retirement, trust, and estate planning. 

My team advises clients on the tax implications of foreign investments in the United States and US investments abroad, offering guidance on matters ranging from pre-immigration planning to foreign pensions and trusts. They also collaborate closely with banks, financial institutions, and trust companies to help them navigate US tax compliance while maintaining relationships with US clients. 

In recent years, the firm has expanded its services into the Middle East, where it has built a strong professional network and advises clients on a wide range of issues, including digital assets, family governance, intergenerational planning, and the establishment of foundations and trusts. 

For support with US tax compliance, cross-border investments, or trust and estate planning, inquiries can be directed to: enquiries.ch@ustaxfs.com.
