Welcome to Frank Hirth

The firm was established in 1975, originally as Frank Hirth & Co - a firm of Chartered Accountants, and offered general accounting and tax services with a particular emphasis on US and UK tax compliance.

It quickly became apparent that we were building an in-depth technical knowledge of the interaction between the US and UK tax jurisdictions and we used that knowledge to advise our clients through their complex tax issues.
