Ian Shirley

Director, Tax Resolutions
I am a Director of Crowe’s Tax Resolution team. I represent individuals, partnerships, companies and trusts based in the UK and overseas who are under investigation or enquiry by HMRC, or who would benefit from making a voluntary disclosure to the UK tax authorities. I have extensive experience in handling cases of suspected serious tax fraud (Code of Practice 9 and the Contractual Disclosure Facility) and assisting clients with voluntary disclosures through both domestic and offshore disclosure facilities.

Being the subject of an HMRC investigation can be an extremely stressful experience. I have significant expertise in guiding clients through this challenging process, helping them manage the pressure and achieve the best possible outcome. 

What I Do

  • Disclosures under Code of Practice 8 & 9 (the Contractual Disclosure Facility)
  • Disclosures of suspected or actual serious tax fraud, dealt with civilly by HMRC
  • Voluntary disclosures to HMRC for individuals, companies and trusts
  • HMRC Penalty negotiations and suspension applications
  • Advise on HMRC’s powers
  • Deliver seminars to accountants and professional bodies on subjects relating to tax investigations
 

My Clients

  • Individuals
  • Partnerships
  • Companies and their Directors
  • UK and overseas Trustees
  • Overseas corporate services providers
