Tax Investigations | Business Legal Services | Irwin Mitchell

What We Do

Our tax investigations team can help businesses and individuals subject to an investigation by HMRC. We can also advise taxpayers on issues not known to HMRC, to make a voluntary disclosure and bring their tax affairs up-to-date.

We can assist in the following matters:

  • HMRC enquiries
  • Code of Practice 9 investigations (the Contractual Disclosure Facility (CDF), where HMRC suspects tax fraud)
  • Code of Practice 8 investigations (avoidance)
  • Liechtenstein Disclosure Facility, and crown dependency disclosure facilities
  • Other disclosure facilities
  • Residence and domicile investigations
  • Missing Trader Intra-Community (MTIC) fraud investigations (carousel fraud)
  • Other HMRC disputes and investigations
  • Alternative Dispute Resolution
  • Criminal investigations and prosecutions

HMRC are becoming more sophisticated in the use of data to assist their risk-profiling of taxpayers. That means there is a greater chance that HMRC will identify those taxpayers who have not paid the correct amount of tax. The level of penalties for making a mistake with your tax affairs can be severe. That makes an early assessment of your position essential.

Our tax investigations specialists have experience helping a wide range of clients, across all business sectors, including:

  • Individuals (including company directors)
  • SMEs
  • Corporates
  • Offshore Trust Companies
  • Professional advisers requiring specialist advice for their clients
