Specialist expertise

Joe specialises in helping clients to resolve tax disputes and guiding them through HMRC investigations, enquiries and disclosures. His clients include individuals, partnerships and owner-managed businesses.
Joe is highly experienced in dealing with all types of HMRC enquiry. He helps clients to minimise unnecessary tax, interest and penalties and, in the most severe cases, avoid criminal investigation. He also advises individuals suspected of tax fraud who are being investigated by HMRC under Code of Practice 9 (COP9).

As Joe is an ex-HMRC investigator, he has extensive knowledge of its inspection powers, assessing time limits and penalty procedures. Joe is also highly skilled in identifying HMRC’s concerns and restricting enquiries to those isolated issues.
