Welcome

Frank Hirth is a leading specialist taxation and accounting practice.
The primary focus of the firm is advising on all matters relating to the interaction between UK and US taxation and the effects that has on individuals, corporations, partnerships and trusts.


We are dedicated to providing first class professional advice and compliance services to our clients based on technical excellence and integrity.


The business was founded in 1975 as a firm of Chartered Accountants and incorporated as a PLC in 2000. Since then it has developed into one of the most respected practices in the field of international taxation and is recognised as a leader in the specialist area of US and UK expatriate taxation. 2008 marked another milestone in the firm’s history with the opening of an office in New York, Frank Hirth LLC. This significant development will now enable us to provide a more comprehensive range of services to our clients based in the US.


Our core client base is made up of high profile international individuals and businesses with US, UK and European connections who require cross-border taxation and accounting advice. We also assist them in meeting their US and UK compliance requirements and where appropriate, in other jurisdictions through our extensive network.
